Colorfull Vertical Line

[JM]

Good Evening Guys..

I'm experiencing a vertical colorfull lines, when I unlock my phone.. But it happens rarely, it's just a split second.. lines from top to bottom, is it because of the software update 254? Like the backlight problem we're facing right now?

I suggest checking Developer options, as you may have accedentally set it up.

Menu > Settings > Developer Options > Untick everything.

let me know if this helps.
