Proximity sensor not working properly after battery replacement
I'm having a problem with proximity sensor reacting to covering after I've replaced battery. The screen hasn't been replaced, just glued back in with precut adhesive stripes. I've checked sensor with Sensor Test app available on Play Store to check if it actually reacts to anything and apparently it does work when i cover it with mirror-like object but not others like it should.
What could be the problem here?
Edit: if it matters when I started unscrewing midframe screws one of it was very lose and when I screwed them back I've tightened that one tighter.
Questa è una buona domanda?
