Alright I finally got a good picture of this happening. See the very faint horizontal lines?
This only appears under certain conditions-
Only when I touch the screen and only after I lock/unlock the phone for the first time after a reboot. (It's fine before that first lock/unlock)
Solved! Go to Solution.
I am very sorry to hear of that line on the screen. I can understand the frustration and annoyance with it!
I have two articles that address issues that could be the cause and may help.
1. Pink lines or dead pixels on Galaxy phone or tablet's display This article contains steps for correcting pixel issues and includes steps such as testing the phone in Safe Mode to rule out 3rd-party app issues.
2. Cracked or bleeding screen on Galaxy phone or tablet This article describes when there is actual damage to the screen and provides links for service options. In the U.S., you can also contact customer service at 1-800-726-7864 to create a service ticket for mail-in service.
