In view of the failure of my small C power button. I've repaired it a few times on and off, but it's not good.

A few days ago, I wondered why he couldn't be good, but I still like to do it myself. So I disassembled the phone again (note that the warranty of the mobile phone is instantly gone), this is the third time to disassemble!

After disassembling it, I thought, what should I do this time, just put some paper under the switch part to try, so I found A4 paper, folded it in three layers, and cut it to the right size. It was padded under the elastic sheet, on top of the plastic structure, and I tried it after installing it. Okay, is it just like that, I was happy in my heart.

Quickly tighten the screws, repeat 15 more times, and it's really good. It's as sensitive as it was when you bought it.

I used it for 5 days before I came to write it down. Those with strong hands-on ability can solve it on their own. Of course, I can't guarantee 100% whether there is an i effect or not, but I can say that my own is completely solved.

If the phone's touch screen is out of order, or if it's not sensitive, you can try the following methods:

To ensure that the touch screen is operated correctly, the finger touches the button or icon accurately when clicking, and the finger remains in contact with the screen when swiping.

1. In order to prevent the application icon from accidentally touching the top when clicking the virtual button, a small touch blind area is set at the top of the virtual button. At the same time, there is also a touch blind zone in the middle of the three navigation bars. In addition, in order to prevent the application from being launched by mistake, when you click the icon on the desktop to open the application, you need to click to the middle of the application icon to launch the application.

This is a native Android design, in order to avoid accidental touches, sometimes it does not respond to navigation bar actions. It is recommended not to click too fast continuously when operating the virtual buttons.

It is recommended to dry your fingers in time, clean the screen regularly, and keep the screen clean and dry.

5. Check if the glove mode is on. Glove mode will increase the sensitivity of the touch screen, if you don't need to use it, it is recommended to turn it off.

6. You can check whether the screen film is thicker. It is recommended to replace the film with a thickness of no more than millimeters.

7. Some third-party software, such as "one-key lock screen", will conflict with the lock screen that comes with the system, resulting in the phenomenon of screen jumping, such as jumping to the lock screen interface, camera interface, etc. It is recommended to uninstall third-party software such as "one-click lock screen".

8. It is recommended to restart the phone. Too much software running on the phone will cause the touch screen to become unresponsive.
