What if the mobile phone becomes a white screen?

First of all, the best answer depends on what kind of mobile phone it is. If it is a flip type or a canopy type, it is generally necessary to take a look at the cable. If there is no problem with the cable, brush it and sit down, and then install it to see if it works!

In fact, many times the phenomenon of "white screen" we encounter can be solved by ourselves, that is, the fake "white screen", while the real "white screen" can only be solved by brushing the machine at present. Let's divide the true and false "white screen" into two parts to explore the mystery and announce the solution in detail:

First, the solution to the false "white screen" phenomenon:

If your NG has a system error or a so-called "black screen" problem, you can solve it by the following methods:

1. Try to start the computer (you can skip this step if it can start normally).

A. take out the battery and SIM card. If the program running in the background (such as T9) is not installed on the E disk, the SIM card and MMC card can be taken out at the same time, and the battery can be installed after a period of time.

B. If all the above methods fail, please press and hold the pen key at the lower right of the keyboard, and at the same time press and hold the power-on key to turn on the computer. After the "NOKIA" sign appears on the screen, release the power-on key and enter the safe mode after success (the system will not enter the safe mode when it is running normally).

C. If the above methods still fail, press and hold the pen shape, press and hold the power button at the same time, and then press the middle of the left keyboard navigation key quickly and continuously. After success, you can enter the menu interface of the mobile phone.

2. Format the phone to solve the problem (if there is no system conflict or error prompt on the phone, you can skip this step).

Exit the phone to the standby interface, enter "*#7370#", and the phone will appear "Restore all original settings? The device will be restarted ",press" Yes ",then enter the password" 12345 ",and the mobile phone will be restored to the factory state after restarting.

2. Reasons for the false "white screen" in 2.NG:

1 disk C and NG mobile phone use related issues;

A. When playing games with ng, use another mobile phone to transfer a file of about 900KB to the C drive of NG via Bluetooth, and the mobile phone is "white screen".

B. When the mobile phone formats the MMC card, it is convenient to copy the photos and materials in the card directly to the C drive. Before the copy is finished, the phone prompts an error, and the screen is "blank" after restarting.

C. Automatically turn off the computer after accidentally deleting the unknown file on disk C, and manually press the arrow keys and pen keys before turning on the computer. The screen only flashed a few icons, then turned white, then turned black, and there was no response.

Reason: a.b mentioned in this article is a "white screen" that can't be turned on due to insufficient capacity of NG mobile phone. You can try unplugging the battery for a long time and solve it by the above method. If the phone doesn't work, you have to brush it. The C phenomenon mentioned in this paper can no longer be started, and can only be solved by brushing the machine.

Tip: Keeping a certain space and capacity on the C drive of ng mobile phone is a necessary condition to ensure the normal operation of the system. If you need to install large-capacity files, please choose to install them on MMC card. Please don't delete the files on disk C.

2. Problems related to Q9 and T9 input methods:

A.NG receives a short message while listening to MP3, and directly switches to the Q9 menu to open. Results After the phone is restarted, it prompts an error, but it can be used normally. After a period of time, the mobile phone can't enter the system after restarting again, prompting "the device failed to start and contact the retailer", so it can only be turned off and the battery is pulled out for processing.

B set the downloaded Logo with SeleQ and restart it, but it can't enter the system. When the battery is unplugged and restarted, an APP error message will appear, and the input method of Q9 or T9 cannot be used, and the text is garbled. The same problem will occur after deleting the input method and reinstalling it, and then the screen will be blank.

Reason: The above two columns are fake "white screens", which can be solved by "trying to turn on the phone". After the phone is turned on successfully, it can be formatted to restore the function of the phone.

Tip: Q9 and T9 input methods are not specially designed for NG, so they are not well run-in, but they must be used. Therefore, when Q9 runs in the background, it will definitely conflict with some programs, and the operation of frequent switching is more likely to conflict with other software. Therefore, Q9 should not be turned off and uninstalled at will after opening, so as not to increase the risk of black screen.

3, modify the operator logo caused by white screen related problems:

A. I made a picture on the computer, ready to make a Logo and send it to my mobile phone. After setting it with Sele Q, the phone is blank.

B. Replace the Logo of the system with a well-made Logo that meets the size, and restart the screen with SeleQ.

Reason: Many players report that changing the Logo will leave the phone blank. Some people think it's SeleQ. There will be a black screen when restarting with software, but many people modify the Logo more than once, no problem. In this case, the black screen after restarting after ng is set to offline mode is the same. This problem is usually solved by trying to turn on the phone. If not, it can only be solved by brushing the machine.

Tip: Modify the system files as little as possible or not.

4. Problems related to not closing the application before shutting down.

You are playing a game, just press the hang-up button to quit, let it run in the background, and the phone will restart the white screen in an hour.

Reason: The non-C disk program running in the background has not terminated shutdown or restart, especially the MMC card has poor compatibility, which may lead to system crash or error. This situation can be solved by trying to turn on the machine, if not, you can only brush the machine.

Tip: avoid restarting the phone when the C disk software is not running. Don't set up a program that automatically runs E disk (MMC card) at startup, and try to quit all programs running in the background before shutting down.

5. Problems related to the use of MMC cards:

A. When using SeleQ, plug in the USB cable, the system will report an error immediately, and the screen will be blank after restarting.

B. While playing MP3 with USB and computer (music files are in MMC card), the result is wrong, and the screen is blank after restarting.

C accidentally unplugged the data cable connecting ng to the computer for several times, and pressed the NG menu button, the screen flashed several times and could not be turned on.

Reason: The above three phenomena all occur when NG controls access to MMC cards (different from compatibility problems between NG and MMC cards), such as simultaneous access to MMC cards by systems and applications or simultaneous access to multiple devices (programs). Because of NG's fragile memory card access mechanism, this kind of white screen can't be solved by itself, and it can only be solved by brushing the machine.

Tip: When connecting a computer with a USB cable, try not to use programs in ng (such as SeleQ MP3 player) to access MMC cards.

6. Problems related to hardware damage:

Hardware damage will also exist, that is, when all methods have been tried and there is no effect after brushing, it is a hardware problem. The only solution can only be to replace parts.
