So, I have red 64gb model. After 20 days of use I noticed theres horizontal gray line on screen while turning on, appears for a few seconds and then disappears. Had other issues- jumping cursor, washed out colors, icons flickering, so I had repair. First time they performed dfu restore, line was still there while turning on. So after second repair they changed screen. The gray line is still there, never at the same position. Cursor still jumps occasionally and screen flickers from time to time. Anyone else with this problem? Thank you. ps. I took iPhone for third repair, they saying everything is ok.
