My poco m7 pro is showing black screen
It's been around 1.5 years since I bought this phone and out of nowhere one 4-5 black lines appeared on my phone and brightness gradually increased then phone goes black for 2-3 seconds and goes back to normal.
I immediately checked if there were any updates pending, I updated the software and rebooted. It went back to normal state but then next day , it just went black and unresponsive, nothing I was doing worked, even the force restart didn't work, after half an hour it went back to normal, and now this keeps happening 4-5 times a day , its been 3 days, what do I do 🥹?
What's happening? can anybody tell me?
