iphone4s blue screen, how to restart

The reasons for iPhone4S automatic restart are as follows:

1.Check whether the installation is abnormal and causes automatic shutdown;

2.Whether the metal removed from the battery is loose or damaged;

3.If you have a battery problem, you need to find an after-sales replacement;

4.Software problems, has there been any incompatible software installed recently that causes automatic shutdown;

5.Hardware problems, this needs to be found after-sales testing to determine the problem.

90% of the problem is with the plugin reinstalling the plugin, deleting the plugin or reinstalling the system.

Restore factory mode and then re-jailbreak, I guess that's all it can be.

Here's how to solve the problem:

1. The first thing to do is to restart your iPhone and press the "Sleep Wake" (also known as the power button) and the Home button at the same time until you see the Apple logo displayed on the screen.

2. Some users solve this problem by selecting "Settings" - "General" - "Reset" - Reset All Settings. The user will need to re-enter the password, change the wallpaper, and reset the Touch ID, but the user's data will not be deleted.

3. Users who encounter iPhone touch screen failure also solve the problem by restoring factory settings, but all the information on the phone will be lost, so users need to back up the important data in the phone in advance. After that, users may need to set up their iPhone like a new phone, and some users say that restoring backed up data from iTunes or iCloud will cause this problem to arise again.

If you have jailbroken, it may be that some software is incompatible, and you may want to think about what software you have installed before.

If you haven't jailbroken then you may have a problem with the machine itself, go to the after-sales inspection machine, they should be able to find the cause of the problem.

I haven't encountered it, so try it after recovery.

1、Generally, it is the problem that an application of the system is incompatible, I just bought it back for 1 month, and there was a black screen 5 times, and finally after the after-sales inspection, the system was restored to normal.

2. If the home button and power button are useless, and the charging only reacts, it means that it is a battery problem.

3. If any buttons are useless, charging is useless, and connecting to the computer is useless, it means that the motherboard is a problem or the screen is aging.

After reading the description of the landlord, it is likely to be problem 1, don't worry, there are thousands of people across the country who have encountered the same problem as you, and it will be solved after the next sale, and by the way, you can sprinkle your anger on the after-sales body.

You should be jailbroken for 4s, but the phone will be unstable after jailbreaking, which is normal.

The standard for checking the iPhone is to connect the phone to the computer to see if iTunes can recognize it, the fake iPhone is all Android kernel, and it can't be connected to iTunes.

3. Find "Documents & Data" in iCloud and open it to enter it.

4. Click the switch on the right to turn off the switch that has been turned on for "Documents & Data".

5. Remember to take a look at the prompts that appear. Then turn it off, and then you can disable the iWork suite in the iCloud sync option.
