After 2 months of using the Q Explorer 3rd generation a white line would sometimes appear from top to bottom on the screen. At first sporadic, but now never leaves. Anyone have this problem?
Welcome to Android Central! Does the line show up in a screenshot? If not, then it's likely a screen defect. I'd make sure all of your important data is backed up or synced on a regular basis, in case the screen is about to fail.
