I have created a ticket to check if I can get a replacement because mine definitely has touch problems.
I have reset to factory settings, and tried with Developer options>show touches and I can see that it is not registering all my touches.
Also tried drawing apps and there are problems even drawing a line
If anyone else has bought the case the turns off/on the screen, can you verify that if you fold the cover back the magnet locks the screen? Because it does that on mine...
