Weird issue.

[OzgurErdogan]

When I want to delete an pic from album or want to start whatsup video call, I can not confirm deletion by selection yes in vertical mode, but in horizontal mode no problem. I have no other issue but this is really annoying. I tried many thing like factory reset, downgrade firmware.. 

What could cause this stupid issue?

@OzgurErdogan 

could you test the phone in >>> safe mode 

[OzgurErdogan]

I tried that. I only can not click yes when deleting a pic from gallery and click start when making a video call in whatsup. Other confirmations are fine :))

That's quite odd

Could you test the touchscreen on both modes?

Settings > About phone > Diagnostics > Test

Oreo

Settings > Support > Tests

No problem att all. All tests are fine.
