Everything was okay with my LG G2, this phone is awesome, but one day screen started to play with itself, literally. I'm guarded with 2 years warranty and of course I went to service center. Problem was found - screen is bad. Screen was replaced with new one, but after I took it I noticed strange vertical lines. In the dark room everything was at "easy" level, in the not dark room "normal", and outside "extreme". I tok some shots with my Lumia 720, but in real life everything is 20 times worse. You can see photos below and I recommend to zoom in - then you will see the lines better.
Of course, I went back to service center. Service guy had another broken G2 and we compared both: yeah, mine with new screen has vertical lines, another broken G2 not. So we decided to sent phone to repair center again. Repair center response: all G2 looks the same, as mine. Of course I came back angry to service center for my phone and little guy told me maybe it's new LG screens for G2, better screens (wow, with vertical lines, way to go LG). And lines is in any case: phone is turned off or not.
I went where I bought phone - to my carrier. Nice lady took brand new G2 from box, we compared phones and yeah, factory G2 not have vertical lines once again. I have even four theory's! 1. I have defected screen. 2. I have defected screen and service center guys are idiots. 3. Service center guys thinks I'm an idiot. 4. Only factory G2 (not repaired) not have vertical lines.
Any suggestions G2 owners? Thank you.
