I have a Samsung A30 phone which I purchased in July 2019. Since yesterday morning, bright vertical lines occurred at the right corner of my screen. It started with single green line and then progressed to multiple green, white, red and maroon lines (majority are now white) within 4-5 hours. I did not even drop my phone. Phone was in my pocket and I was roaming outside in a moist and wet weather (after rain stopped). At that moment I noticed green line.
I also got my screen replaced 1.5 months ago from a local repair shop instead of Samsung service center. I got the AMOLED screen. The reason for screen replacement was blackout after a fall. Now I have suspicion on that shop.
I did all the software related troubleshooting techniques, still these lines haven't gone away. I did reboot, safe mode and factory reset, still no relief. It is indeed a hardware issue. My power button also stopped responding a week ago. My screen was not properly responding to touches yesterday afternoon.
