Last time, I accidentally pressed the factory settings and broke the touch screen of Huai Limb, and finally I pressed it many times and repaired the touch screen again. Tap the screen a few more times. If it was Huimu's touch screen that had broken Qianmingsen a long time ago, then I had to find a replacement screen for repairing the phone, which was not expensive.

The touch screen** is between 40 yuan and 25 yuan, and the factory settings are restored, which does not affect the normal use of the mobile phone.

There's no way, it's too expensive to repair, just change the phone.

The original is more than 200 points, and the general one is about 150. There's no value in repairing, this machine is not worth much.

My new Tianyu A650 here is only 300 yuan, so it's good for you to buy a new one.

1. You take out the battery first, then put it back, and then turn it on to see if it can be good;

2. Try to restore factory settings: (Turn off the battery first, take it out, and then put it back, don't turn it on.) Turn off your phone – press "Home.""+ Power on button to enter Recovery - Enter Wipe Options - Select Restore Factory Value Wipe Data Factory Res - Restart the phone.

Note: If "fastboot mode" appears during operation, the power button is sure to select fastboot mode.

3. If the boot is still stuck in the boot interface, it may be: (1) the system process is abnormal and cannot be entered; (2) The system data cannot be loaded due to the abnormal data of the motherboard.

Hello, the outer screen you are talking about should be a touch screen.

If it's a touch screen.

That's not expensive Generally 30--40 yuan, in fact, the touch screen itself is not expensive, but the maintenance personnel have to add manual, it is about 30--40 yuan (different from place to place, for reference only).

It is best to replace the touch screen in time after it is cracked, otherwise it will be much more expensive because the crack squeezes the LCD inside, and if the LCD is damaged.

In addition, how can the landlord judge that the touch screen is broken, maybe it's just a matter of calibration.

Mine didn't break, and when I didn't want to calibrate, I just pressed the AFK button, and you should have pressed it too.

The system is damaged, just brush off the machine.

There's no way around it! So is my phone! Later, I had no choice but to buy a new one today!
