I searched through a lot of topics and comments but I couldn’t find the exact problem I have.
My screen stays black when I press the power button, but when I put pressure on the edges (with my thumbs) the screen appears. Only I can not use it. It doesn’t react. I used to be able to use it (after I did that thing) but not anymore. Then the screen fades out.
Also sometimes the power button just works for no apparent reason and the touch screen works too. But that doesn’t happen very often now.
Shutting the screen off works all the time.
Once I brought my phone to a repair service. They cleaned it and it worked for two days. Then I had the same problems again.
Do you have any ideas?
