In fact, the white screen is a protective measure for the mobile phone, because the power suddenly fails, so the mobile phone will be white, maybe your battery has been tossed by you, you must pay attention when charging, don't always play games or play **, because it often leads to no power, even if it is full of electricity, but it is also virtual electricity, it is not long, charging is particular, you must use a standard charger, and it is best to shut down the computer. It takes about 6-9 hours to maintain the battery and prolong the life of the battery. In less than 1 month of use, your phone will basically be back to normal.

The easiest way is to go to the regular store and try it again.

The following is for reference.

The white screen is generally a hardware problem, and there are many LCD problems.

Here's how to find out if it's a software problem.

1. Turn off the phone and turn it back on, listen close to your ears to see if there is a boot of nokia**. If there is, it means that the software is fine.

2. After turning on the machine, press the keyboard close to your ear, if there is a key sound, it means that it is not a software problem.

3. After turning on the phone, dial 112, if you can talk, it is not a software problem.

If the above triers fail, you can only send them after-sales.

It may be that there is a problem with the battery, try to change the battery first, and then flash the machine.

There are usually three reasons for the white screen of a mobile phone: one is the hardware, one is a software defect, and the other is the operation of the camera phone.

First of all, there is a contact point between the upper and lower cover of the mobile phone, which plays the role of connecting, hanging, closing the inner screen and opening the outer screen. The control of the inner and outer screen is a small bulge above the keyboard, when this small bulge is pressed on the corresponding small groove, it means that the phone is closed, the inner screen is extinguished, the outer screen is ignited, and when this small bulge is not pressed on the small groove, it means that the phone box cover is opened, the outer screen is extinguished, and the inner screen is ignited. If the lid is not tight after using it for a period of time, the small bulge cannot be pressed well to the end, and the outer screen is not bright, and when the lid is opened, the groove cannot be completely up, and the inner screen is not lit, and a white screen appears.

Also, the clamshell machine is prone to a white screen, which is mainly caused by the poor contact of the connected cables, and it will be displayed when it is contacted, otherwise it will be a white screen. In this case, you need to open the re-soldering contacts, if it doesn't work, you can only replace the cable, and if you happen to encounter a cable that is not sold separately, you can only replace it in full screen. There are also some reasons why the screen does not display is caused by the motherboard, mainly due to damage to the circuit and power chip, which causes the display to not be able to supply power.

If you can't eliminate the fault after opening and closing it a few times, but after shutting down and turning it on, it can solve the problem, then it can be roughly regarded as a software problem, and you should go to the repair center to test the mobile phone and repair it.

In addition, some camera phones appear white screen phenomenon when taking pictures, then it may be caused by improper adjustment of **degree, that is, consumers adjust the **degree to +2, because ** is too high, then the screen will display white. In this case, it can be solved by lowering the ** degree, and it is not a problem with the quality of the mobile phone.

Smartphones are more likely to have a white screen.

A mobile phone is called a smartphone, and it needs to be seen if it has an independent scalable operating system. Scalability refers to whether it can support the installation and application of third-party software. In other words, a smartphone is a hardware platform that runs on an independent operating system, and the "smart" functions we need are based on this operating system.

Smartphones, like computers, are generally most prone to crashes in two phases. One is when I first bought it, and the other is the few days when I already have a certain understanding of the system of the mobile phone and start DIY and install software. Why?

Because when you first buy it, users don't know about smartphones at all, and there are usually many misoperations, which will naturally crash and restart; Then, after getting familiar with the operating system, users understand that the functions of smartphones rely on massive software to achieve, so they start to install software and games, and at the same time do not pay attention to management, crashes are inevitable.

If there is no computer that does not crash, then there is no smartphone that does not crash; If you use your smartphone as if it were an ordinary phone and don't install any software, then it will never crash, and it's the same for ordinary phones that rarely crash. There is no need for us to give up such a powerful tool as the smartphone because of choking.

Finally, in order to minimize the occurrence of crashes, white screens, or automatic restarts, the author would like to put forward some of the experiences he has summarized in actual use, which can be regarded as the author's suggestions for using smartphones.

1 After buying a smartphone for the first time, you should check out some smartphone forums on the Internet before using it. Generally speaking, these forums will have precautions for the use of related systems and related models, and understanding this knowledge can save you a lot of detours.

2 Do not open several programs at the same time when using a smartphone, generally less than 3 is appropriate, and large programs can only run one at a time. Try to exit the program by relying on the menu to exit in turn, and do not use the AFK key directly. In that case, the program is still running in the background, and if you open a larger program, it will easily freeze.

3 Try not to install software from unknown sources, the first person to eat crabs is not easy to do.

4 Pay attention to the protection of the memory card, the damage of the memory card and the wrong data stored in the card will cause the failure of cyclic boot or failure to boot. If you encounter this kind of failure, you should first try to format the memory card, if not, you can only replace the memory card.

5 Manage the apps on your phone and don't delete files that you think are unnecessary. Some of the crash failures are caused precisely due to the user deleting the system files by mistake.

6 Smartphones, like computers, will become disordered after a long period of use, which will slow down the operation of the whole machine and cause it to crash easily. The solution to this situation on a computer is to reinstall the system, and the smartphone is to hardformat. After hard formatting, all the data on the phone will be erased and the file system will be restored to the factory state, so we need to make a backup of the relevant data before hard formatting.
