Touch clicking the wrong position

aerius

Hello,

After an upgrade to Android 7.x with SP Flash Tool. The touch has screwed up. When I click the bottom button it clicks to the left instead. When I click of screen button it clicks bottom. So no position I click are translated correctly to the screen. I can click anywhere on the screen but the "phone" clicks elsewhere always.
What can I do to fix this issue? My phone is unusable.

Best regards,

Also you can perform factory reset after OTA update as maybe you have some error during downloading or updating procedure.
Please use SPFT and flash you system.
Here you have SPFT updating procedure

And here you have all available ROMs (the first on the top is latest Android 7.0

If this doesn't help you need flash to latest Android 6.0 and then to 7.0 with preloader unchecked.

Thanks. I flashed Android 6.0 and then the touch started working and then I upgraded with the 7.0 release I've used and it works.
So thanks!
I don't know how I did not think of that.
