The touchsreen is not working properly

[flopiflop]

Hey!

This morning, after downloading some app from the play store, the bottom of the touchscreen stopped working.

After some complete reset via the mobile (factory setting) and the computer (with pc companion), it seems like it doesn't work only when the home button appear.

I tried the diagnostic tool (on settings/about phones) and all the screen is working.

Even when the mobile is locked I can access the google now button and the camera button.

So, I fell like it was a virus, even if 3 resetting was made... So I tried antivirus and antimalware like avast and Malwarebytes.

Did anyone have an idea?

My phone is not protected by the warrantly now 😕

Sometimes the home button work properly but only 2 or 3 times.

Sorry I forgot to mention that I already tested the safe mod too ^^'

Is there an official tutorial for that?

Anyway I think I'll try it

Ok it was quite easy to downgrade but it sill doesn't work.

It's really weird, the bottom of the screen work when there is no home button (like in the first tutorial of the mobile) but when this button appear it doesn't work anymore... 😕
