Is my phone have any problem? Red line appear on my phone screen. It keep poping up like ads. It appear less than 1 second in 1-2 Minute. I'm using Xpedia Z2. What does it mean? Please help.

Hi,

Does this line appear when you use any specific app or similar? Do you experience the same behaviour if you boot the phone into safe mode?

@Mpapus

if it doesn't on safe mode then it's a third party app if it does then repair the phone with PCC and report back, if possible post a screenshot or video of the issue
