Smart phone, a popular term is a simple “1 +1 =” formula, “Pocket PC + phone = smart phones.” Broadly speaking, the smart phone addition to the phone call functions, but also has the most PDA functions, in particular, personal information management, and wireless data communication based on the browser and email functions. Smart phones provide users with enough screen size and bandwidth, which is convenient to carry, but also for software and content service providers to run a big stage, a lot of value-added services can be started on this, such as: stocks, news, weather, traffic, commodities, application downloads, music and picture downloads and so on. Integration of 3C (Computer, Communication, Comsumer) smart phones will become a new direction for the future of mobile development. A smart phone by the necessary number of conditions: 1, with all the features of ordinary mobile phone capable of normal voice, text messaging and other mobile applications. 2, with the capacity of wireless access to the Internet, that need to support GSM, GPRS or CDMA network under the network under the CDMA 1X, wifi, or 3G network. 3, with PDA features, including PIM (personal information management), program notes, tasks, arrangements, multimedia applications, browse the Web. 4, with an open operating system, in this operating system platform, the application can install more programs, so that the functions of smart phone can be unlimited in Kuochong. OS ▼ Symbian OS: Because so popular fashion, the most widely supported further and further away. Symbian currently designed, stable, and there are many vendors support promising. Now it is very strong network applications. 9 keys very comfortable one-hand operation. Little disadvantage. Symbian’s like a combination of Windows and Linux, have a good interface with the kernel and interface separation, low hardware requirements to support the C + +, VB, and J2ME. Representative models: Nokia N95, Nokia E90, Nokia N96, etc.. ▼ WM: is Microsoft for Pocket PC and Smartphone software platforms. Windows Mobile will be familiar with the Windows desktop, extended to the personal device. Microsoft Windows Mobile handheld devices for the launch of the “mobile version of Windows”, use the Windows Mobile operating system devices are mainly mobile phones, PDA, portable music player. Windows Mobile operating system has four kinds, namely, Windows Mobile for PocketPC Edition, Windows Mobile for PocketPC Phone Edition, Windows Mobile for Smartphone Editon, Windows Mobile for Portable Media Centers. The latest version is Windows Mobile 6.5. 2010 Summer Pocket PC and Smartphone combines the two platforms windows phone 7 forthcoming. Advantages: 1, interface similar to desktop Windows, to facilitate people who are familiar with computer operation. 2, pre-installed software, rich built-in Office Word, Excel, Power Point, visit or even editing, built-in Internet Explorer, Media Player. 3, computer synchronization is very convenient, fully compatible with Outlook, Office Word, Excel and so on. 4, a powerful multimedia features, with third-party software can play virtually any popular format for audio and video files. 5, touch operation, can be comparable with the iPhone. 6, extremely rich third-party software, especially dictionaries, satellite navigation software can be run. Disadvantages: 1, of the people who are not familiar with computer operation more complicated. 2, on the hardware requirements higher. 3, slightly larger size, many operations require the use touch pen. ▼ Linux: give you a reason to love it, lack of security, performance is low. Linux is open source, software licensing fees low, application development, the advantages of rich human resources, to facilitate the development of personal and industrial applications. Started too late, there is no solid foundation. Representative models: Motorola A760, Samsung i519. ▼ Palm OS: please look at me, features a single user little. Palm, the hardware requirements of such systems is very low, so prices can be well controlled, very small power consumption. Distinguishing feature is much faster than other systems, operating comfort, stability, if not use bad words (not something familiar). However, relatively few in China to help it to write software for the Chinese people less. Web applications are poor. Representative models: Samsung SGH-i500Treo 600. ▼ Android: it is “Android” transliteration come, so that in China, “Andrews” is a direct representative of the Android mobile operating system. ▼ iOS4: iPhone OS 4 renamed iOS 4, the function of upgrade is mainly reflected in the following aspects: a revolutionary multi-tasking iOS can tell from the side songs, download, while online, send and receive messages. 2, iOS 4 Another important upgrade is to support the archive folder on the process management software, users can drag a few a custom folder name management. 3, iOS4 mail management when there is a unified inbox
Concept phones
Like the concept of mobile phones and concept cars, apparel or fashion is like the popular cell phone just informal, is more conceptual, such as mobile phone watch is the concept of the table cover on the phone, and cube mobile phone, mobile phone or pyramid , is the concept of the pyramid and the cube given to the phone, as well as projection SMS, etc. In fact, little practical function, but conceptualized it. Concept phone with concept cars, is a strong capital and advanced design concept of the company, in order to reflect the current strength of the company, and demonstrates the company on future market direction and specially designed products. Usually not intended to market and profit in the near future, but the main purpose is to attract consumer attention, shape the company’s strong technical strength and excellent image design capabilities.

USIM card
USIM card is the third generation mobile phone cards. Many people think that in the 3G era, most applications can only be achieved by a mobile phone, the card only limited resources to achieve certification function on it. Indeed, 3G applications are very complex, most of the applications are STK card can not be completed alone. USIM card, but not only do simple authentication, the fact that it is gradually moving business platform, as well as the final transition to multi-application platform, on mobile phones, e-purse card, electronic instruments and other applications are no longer difficult. This feature makes USIM card into a different cross-industry cooperation and mutual penetration of media business, such as banks can participate in the telecommunications business, and vice versa. In addition to support multiple applications in addition, USIM cards are still the algorithm in terms of security upgrades, and added the authentication on the network card, this mutual authentication to prevent hackers can attack the card. Meanwhile, USIM card, more powerful phone book up to 500 phone numbers stored, and for each call, the user can choose whether to input other information, such as email, aliases, and other numbers. Despite faltering, but 3G is coming to us step by step. The high cost of 3G licenses may be stagnant for many operators one of the reasons, more importantly, they support 3G applications to wait and see attitude. And the realization of USIM card based multi-application there are many issues to resolve, such as the relevant standard is not perfect, the lack of support for this multi-application mobile phone, more importantly, operators and related businesses or government agencies-ordination will increase great difficulty of this application. In any case, the third generation mobile communication card in this regard has already done the technique, I believe that USIM card based multi-application also will eventually be widely used in the 3G era.

Emergency Maintenance
Portable backup phone every day, while high usage rate, an early case of accident or functional degradation, etc., are relatively higher than any electrical appliances in your house higher. To cope with such as mobile phones do not Shenru water, leading to intermittent auto accidents fell off so often appears disease phones, send for maintenance is the best way of course, but if the phone has some basic first aid, before being sent for repair rescue, reduce losses, save a life mobile phones. Save water in the mobile phone to get wet, accidentally fell into the water was most common, so if you really unfortunate, please do not hesitate to immediately remove the battery to force power to avoid water droplet erosion board. Then sent to repair as soon as possible, is the response. Moreover, the water inside the cell phone hair dryer dryer (only use the heater), water erosion can also reduce the degree of board and also the contingency approach. If you cherish, still continue to use the battery was probably still normal operation, but at most half a month, you will be ignored by the board to save the point of corrosion. Seen prior to the normal operation, in fact, illusory. Use hair dryer drying your phone, remember to set the temperature to a minimum, such as excessive heat may cause deformation of body compound. Phone fell into the toilet, immediately to take it out and remove the battery, put a jar of dry rice and dry. Because rice has a good drying effect. Automatic shutdown of power sufficient to save the phone and in standby mode, but sudden auto-off machine’s condition had a lot of users experience, reasons may be several possibilities: 1. lithium over the role of the protection circuit is sensitive, so a large current to power 2. the battery is already aging 3. handset inadvertent water (part of the phone is not waterproof) 4. the battery contacts the metal bits are dirt, resulting in poor contact power supply 5. the interface between the battery and the phone bit easier to loose. If, after examination, found to be the first two issues, then we must repair to the repair shop. However, if the latter two, the problem only lies in the “metal battery” dirt caused by oxidation, as long as clean with a glue stick to the rubbed situation would be improved. In the battery and the phone pad of paper between the skin or film, you can also solve the battery loose, poor contact caused the problem. Mobile emphasis maintenance so-called “prevention is better than cure”, if the phone each time until the accident and then remedy, may have been too late! Here are five easy to use mobile phones a bad example, are often guilty of all the small problems, if you can do, you can make your phone safe. Avoid one: avoid touching the metal SIM card, destroy or damage any scratch will lead to SIM card can not be read. Ji 2: Avoid the phone outlet on the air-conditioned, because condensation of water vapor in the mobile phone will be invisible to corrosion board. Avoid 3: Charging time enough is enough, usually 8 hours has been sufficient, if the excess charge but will shorten battery life. Avoid 4: bear in mind that cell phone antennas, if not necessary, do not pull out at random or when the same toys to play with, to prevent the reception. Avoid 5: fear of wet cell phone accidents, wear a waterproof bag and waterproof capsule that can protect effect.
Routine maintenance
1, cell phone batteries do not wait until no electric charge. General idea is that we will have a cell phone battery power to recharge is done and all the better is basically true, because we have previously used mostly nickel-hydrogen rechargeable batteries (NiH) batteries, while the so-called nickel-metal hydride battery The memory effect is finished, if tightly, then re-charge will lead to rapid reduction of battery life. Therefore we will use the last drop of power began to charge. But now, mobile phone and IA products generally most of lithium (Li) batteries, and lithium batteries, then there is no memory effect problems. If you run out of power or to wait until then but will then charge the internal lithium battery makes the reaction of chemical substances can not reduce life expectancy. The best way is nothing to charge it at any time to maintain the best full lattice state, so that you can use the battery long long time Oh. This is the message received from the manufacturer that, and obtained through their own testing. 2, when the phone is charging, do not answer the phone! ! Because the phone is charging, the phone calls would be potentially dangerous. India has a 31-year-old office manager at the insurance company of young people, 10 days ago in cell phone charger and then also answer the phone when, after a few seconds a lot of current through the phone, this young man was dropped to the ground, When found, his family, fingers burn with a weak heartbeat and had lost consciousness. The emergency hospital, the doctor announced the death to the hospital. Mobile phone is the most commonly used all the modern inventions. However, we also have to be alert to the risk of death machines. 3.12593 phone number = trap you not to call a friend overseas telephone numbers with 17 951 phone numbers stored in the format of this years? Rather than individual call? Then charges will be from 0.39 (0.4) per minute into 1.3 (0.7) per per minute. I have the 1860 (10086) query over their interpretation is that if stored in the phone number of the years? system will not recognize. So they can not get tariff concessions to each keyboard directly by 12xxx. Shenzhouxing user so? M-Zone subscribers, GSM is the same. If you are a user of China Mobile, China Mobile, when you know you set the following trap, it will no longer be surprised why your telephone bill for as long as the fly away wings. With 12,593 telephone numbers can be offer, but if you advance, “12593 phone number” in the phone’s phone book, use the time out and then dial out of tune, when you use China Mobile does not recognize this preferential dial the 12593 way but in the way of direct dial billing. If you are roaming, billing can be a difference of 7, two times! When I learned that this billing, I really do not know how to express my anger, then hit 10 086 counseling, if not take the initiative to the rule of asking this question, the work number for the 6608 young lady told me it simply does not billing. 4, mobile phone charges parasites somehow useless messages set-up is strongly recommended that everyone look at the bills they have not in the most simple way to unsubscribe from the monthly fee of parasites to steal your phone! 3.15 China Mobile was forced to launch a new business, if you are Chinese mobile phone users, type the number “0000”, send text messages to 10086, an automated response within seconds, a message list, show how customized your phone What SMS, which SMS service provider what is clearly the dark with a monthly fee charged to your mobile phone; type the number “00 000 (0000)”, sending an SMS to 186 201 (10 086), you can unsubscribe from all SMS services. 5, Do not rush to Minato just one minute when we are often called just in time for 1:00 before the end of glad, but in fact not the case, according to a China Mobile’s staff said, in fact, you talk to 0:55 when the operator had a minute, so call time 0:55 ~ 1:00 is count your money in 2 minutes (depending on your cell phone billing accuracy). This knowledge is very important to convey to you, so you phone can be a little longer. Learning a school now! After the rainy day ah!
Mobile Applications
Mobile phone can buy electricity from the purchase of electricity systems in support of Beijing, people (universal or) to get rid of most of the time now to go to the banks line up to buy electricity from the many inconveniences, to easily use their phones to buy “power words”, the whole process only a few minutes, but stay at home to achieve a true “weather” the purchase of electricity. The whole process of purchasing electricity only users with the purchase of electricity function with SIM card platform through the purchase of electricity operators, platform operators and banks, power companies confirmed the transaction, writing cards to complete the purchase of electricity simple steps. After the user remove the SIM card from the phone into the special insert card sets to purchase electricity meter input to complete the whole process of purchasing electricity. The cost of purchasing electricity from the user’s bank account in the bundled payment. This process, users simply use the phone’s STK menus follow the prompts, and through text messages was related to the transactions and confirm the information, and using other mobile services is no different, very easy. mrp download base – the most practical application of mrp mobile games and software download sites. was founded in 2009.

Mobile Phone Battery
A mobile phone battery mobile phone battery, there can be re-activated memory phenomenon. The key here is how to discharge. First of all, must not covet save trouble using wire short the two poles of the battery, this will cause damage to the battery! Some chargers have a discharge function, but this method also has drawbacks. Discharge current than its operating current big cell phone, which also have damage the battery. Besides can not determine whether the call had finished. The best way is to use mobile phone natural discharge, which of course take time. Pumping a weekend cell phone at home when not in use, turn to the phone is in standby mode, and so on and then turn off its own discharge. Usually repeated several times immediately after the turn on they can not, and this time do not think I have discharge is completed, should be placed on a period of time the phone boot. This discharge until the phone is placed repeatedly over an hour, not longer boot, even if the basic end of discharge. Charging new phone activation method and purchased the same way when first charged more than ten hours, and then add charge two to three hours. If you have plenty of time to supplement the charge can be repeated two or three times to do. Second, do not wait until the phone using a very short time to do reduce activation, as would be caused because of lack of time does not fully discharge the battery of memory still left. The use of time after activation will be short. Best use of time when it was shortened to take active measures. Such as the use of new mobile phone time is seven days, when you use the time down to about four days to do on activated. This weekend you can easily finish the activation. Third, sometimes buy a new or re-activate the phone not long after the apparent decline in use of time, then not necessarily memory effect, which may be caused by poor contact. Best to re-activate the phone before the battery and the contacts to do a make clean paint swab: a small cotton swab or toothpick wrapped with paper towel dipped a little paint on alcohol swab on it. Do not go scraping with a hard object, as will add to poor contact. No alcohol can be an alternative high spirits. After use wipe paint on paint on dry paper towel immediately to avoid excess alcohol, open short circuit between the battery poles. Fourth, sometimes the identity of the battery there is no electricity or space is not necessarily a memory effect occurs, it may be the identity function mobile phone battery problems. This usually appears in mobile phone use for some time, determine the solution is simple: When the space charge when not immediately, wait and see whether the phone automatically shuts down very quickly. Of course, no need to check each time, over a period of time to pay attention to what is necessary. Otherwise, the battery will speed up the memory effect. Course, not all mobile phones will appear this situation. 5, mobile phone battery is a weakness, it is the mobile phone in all parts of the shortest life expectancy. Unfortunately, it is difficult to get the battery to replace the original.
Charging Tips
If users want to prolong the battery’s effective use of time, in addition to the quality of the charger should be guaranteed, the right skills is also essential to the charge, because the poor quality of the charger or charging the wrong methods are will affect battery life and cycle life The following is the author sorted out the charging tips: 1. Battery factory, manufacturers have carried out active treatment, and conducted pre-charged batteries have more than electricity, a friend of mine said that in accordance with the adjustment time for charging the battery, the standby is still a serious shortage of batteries assumption indeed genuine battery, then this case adjustment should be extended further 3 to 5 times fully charge and discharge. 2. If you buy a new cell phone battery is a lithium-ion, then 3 to 5 times before the charge commonly known as the adjustment period, more than 14 hours should be sufficient to ensure full activation of lithium-ion activity. Lithium ion batteries have no memory effect, but has a strong inert, should be fully activated in order to ensure the future use to achieve the best performance. 3. Some automated intelligent rapid charger when the lights change direction, said only 90% full. Changing the charger will automatically charge the battery with a slow full. Is best used after the battery is full, otherwise it will reduce the use of time. 4. Before charging, lithium batteries do not need special discharge, discharge improper battery will be damaged. Slow rechargeyour batteries charging as much as possible to reduce the fast charge mode; time should not exceed 24 hours. After three to five times the battery fully charge and discharge cycles of its internal chemicals will be all the “activation” to achieve the best results. 5. Please use the original or the reputation of a good brand of chargers, lithium batteries use lithium battery charger, and follow the instructions will damage the battery or even dangerous. 6. Many users often charged when the phone open, in fact it will hurt the mobile phone life very easily, because in the charging process, the cell phone circuit boards will be fever, at this time if there are external phone, you may create an instant return current, on the phone’s internal parts damage. 7. Battery life depends on the number of repeated charge and discharge, more than it should be avoided when the power is charging the battery, this will shorten battery life. Phone off for more than 7 days, the first cell phone battery is fully discharged, adequate electricity and then use. 8. Mobile phone battery self-discharge exist, not when Ni-MH battery remaining capacity every day by about 1% of discharge, lithium batteries a day by 0.2% to 0.3% discharge. In charging the battery, try to use a dedicated outlet, do not share the charger socket and television sets, home appliances. 9. Although the mobile phone within the network coverage area, but the phone off charge, the phone is not acceptable and make calls. At this point, you can use the phone did not pass transfer function, will be transferred to the side of the fixed-mobile phone to prevent calls lost, this method is not for the cell phone network coverage area or a weak signal is temporarily unable to connect when applicable. Phone 10. Do not expose the battery to heat or cold, like a dog day weather, should not the phone in the car, stood in the scorching sun exposure; or get air-conditioned room, on the air conditioner blowing directly place. When charging, the battery a little heat is normal, but not Jinshou high temperature “suffering.” To avoid this from happening, it is best at room temperature for charging, and do not cover anything on the phone. 11. Nickel-cadmium (N iCd) must ensure that the battery before charging the battery completely discharged, recharge the battery fully charged and must guarantee. 12. If the phone battery to place too long without use, the best maintenance department to apply to cell phones to make a living dealing with, you can own with a direct current constant voltage device, adjust the voltage of 5 ~ 6V, current 500 ~ 600mA reverse battery connection . Note that the liberalization of touch, most can be repeated three times, after such treatment, re-use original charger “adjustment” charge. 13. Charging is not longer, and the absence of protection circuit should be stopped after the battery is fully charged, otherwise the battery overheating due to heat or impact performance. 14. Lithium-ion battery charger must be selected, otherwise it will not reach saturation, affect the performance of play. After charging, should be avoided in the charger more than 12 hours or more, do not be long-term separation of the battery and cell phone to buy mobile phones must come to see.
False failure
There are many primary users, because of the phone features or some settings are not familiar with, 经常 meet all kinds of Gu Zhang, Qishizhexie fault Zhong phone is not really many faults, but the phone Shi Yongzhe or misuse by Cuowurenshi result. Here I will organize a number of false failures are common for the majority of mobile phone users for reference. 1, mobile phone keypad failure. When you hold the phone button on the fingers of a key position, if the corresponding key position on the numbers or symbols on the screen does not appear in the phone, your first reaction may be the phone keypad malfunctioned. It really is the phone’s key bit worse? Before you answer this question, the best should first check your phone settings, whether to start a cell phone keypad lock function. 2, can not activate the phone. If you press the phone power switch, the phone can not start, please check the phone SIM card installed correctly. 3, garbled phone warnings or continuously. WAP mobile phones in use in the process, if you encounter some non-normal conditions, will give some garbled and warning information, if we do not know the origin of these garbled and alert, certainly will see the cell phone problem. An ability to connect to the Internet interconnection WAP mobile phones, downloading ring tones or visit the web resources, mobile phone and computer may be infected with the same mobile phone virus. Once the cell phone infected with the virus, these viruses will be in the phone screen garbled characters, or continue to issue various warnings prompt information, and sometimes automatically activated telephone recording, and recording four transmission, the virus will automatically making a call, delete contents of the file on the phone, and create a huge amount of telephone bills. The above a variety of illegal operations, who just use the phone’s user would certainly think that cell phones have an internal fault. In fact, the failure is due to mobile phone by viruses, you only need a wireless web of mobile phone anti-virus or by phone IC access port or infrared port for virus transmission, we can solve the problem. 4, some features can not be used. The new phone is now emerging, a new phone every hardware or software systems have been changed, if the user did not understand, may be that the phone broke down. For example, now have a new phone with a cell phone screen saver function, this function does not use the phone for the time being, there will be a variety of screen saver images, then if you click a button on any phone, mobile phones will be back to normal. If the user does not know the characteristics of the primary, it appeared that the cell phone display problem too! Also, different mobile phones, has the same function buttons on the location of the phone keys are different, if you are in a location on a mobile phone found at the function, while in another the same position of a mobile phone, did not find the corresponding features to Do not say, “how even this phone features are not ah!” 5, mobile phone can not find the network. At present, most mobile phone users, not into the Unicom network is mobile communications network. Use the results from the practice point of view, the development of mobile communication networks spend more time, more mature and all aspects of technology, the network system stability is also strong, while the China Unicom network only just started, communication technology and equipment is not perfect , and mature, the relative stability of the network is to be narrowly missed. Once the phone to search for less than the corresponding network, the phone will not work, the phenomenon is demonstrated by the external phone connected to a break, often need to repeat to play two or three times; or repeated phone can not get through, neither busy tone, nor shutdown. 6, mobile phones can not call can not be connected. Phone is an electronic device, it will be issued during working electromagnetic waves, electromagnetic waves to pass through this information, once the information in the transmission process, encounter other electromagnetic interference, can not answer the phone can not dial the phone Beginners If you do not know the reason, they would easily mistaken for mobile phones broken. In this case, we should try to keep away from those with strong electromagnetic wave emission source of local, Ling Wai generate electromagnetic interference may be due to the reflection caused by high-rise buildings, so if we encounter the sound off when the phone there should be as far from high-rise buildings. 7, can not send text messages. The use of mobile phones to send short messages, generally what parameters need to be set in advance, otherwise not allowed to send cell phone text messages. Own settings, you can enter information to set the phone interface, the short message service center number is set to +8613800 *** 500 *** on behalf of one mobile telephone area code where the latter three figures, if three of the local telephone area code is , then we top code the user should be removed “0” and fill in the code behind the “0”, for example, I assume that is where the 021 area code, then the region where the author information service center number is +86 XXXXXXXXX, enter the service number after , click OK after the settings can be successful. 8, cell phone signal suddenly disappeared. If the call process, suddenly went into a remote corner of the building or a tightness in strong, or cell phone batteries run out or the cell phone battery and cell phone contact with loose boards, and it is very possible cell phone signal suddenly disappearing phenomenon. 9, cell phones can not be charged. As the charging voltage instability, or the battery into the charger when the position error, or the result of poor contact, etc. can not be properly charged cell phone batteries, mobile phone batteries on the thought that the quality of their own.
Cottage phone
-Name phone jokingly. Is not its technology, products entirely by hand and save documents assembled a small factory making workshop class mobile phone. Its shape is usually associated with some well-known and popular product line is very similar brand and no brand more formal, and even some banner Sunyericcsun, NOKIR, SAMSING this edge ball brand. The mobile phone is often called the cottage, cottage. China Mobile first started cottage marked CECT brand-name mobile phones, actually only fraudulent use of CECT brand or pay some cash to get the right to use CECT. Subsequent emergence of a variety of brands. Work in different ways, no branding, body or back of the common front big BLUETOOTH, TOUCHSCREEN, MP4 and so forth. What dare to print the box, in addition to their real site. In recent years, active in all major TV shopping had never heard of mobile phone brands mostly cottage, a big moneymaker for the TV shopping. The phone features an extremely rich and extremely low prices, great new look, the quality is extremely unreliable. In any case, “cottage mobile phone” can always beat the wisdom of our most frustrating piece of nerve, but also a lack of innovation for some national brands shame. Over the years, the cottage phone number appeared among unmatched in the world of technological innovation, the appearance of innovation, process innovation, a lot of strange technology and design are combined together, these combinations may sometimes be infringing, and had achieved the wide variety of functions. Now, the cottage has become a non-mainstream mobile phone culture, wolves, innovation, the spirit to meet the market’s cottage phones affect more and more people. With the liberalization of national regulators, many cottage manufacturers have “repented”, launched its own brand. Cottage phone now entered a new phase, begun to enter the field of smart phones, but use less cpu, memory less, but the price is quite cheap.
