I have bought an Xperia XZ2 Compact in October 2018. The cell phone is showing me following issues related to display:
1) Pink vertical lines appear on screen when battery is less than 20%. 2) Half Screen Flickering: The bottom half of the screen is repeatedly flickering in home screen as well as while using apps. Sometimes it also turn dark at the bottom side of screen. The issue has become even worse still last 2 days. 3) Screen goes black while in call: The screen goes blank during call and then blinks/flickers sometimes.
I have already tried troubleshooting by following means: - Test feature in Support app for checking touchscreen as well as display. - Factory reset - software repair with Xperia Companion.
Unfortunately none of the measures helped and the problem still persists. It is annoying that a mere 4 months old cell phone is having such issues.
