In the process of using the iphone, for iphone LCD screen display or iphone touch screen, some users may encounter a sudden mobile phone touch screen does not respond to this situation.
When this happens, you need to do this:
The first thing you need to do is press the power button and the home button for about 10 seconds until the phone is turned off to restart, then release the two button, waiting for the boot test screen. If the touch is still not after the boot, you can choose to use the PC brush iTunes.
If you still can't solve it, you need to go after the sales test, or change the phone screen.
We can supply the screen for iphone LCD screen display, for samsung LCD screen, for sony LCD display etc. Hope can help you.
