After lastest update on my device IQOO 9SE today 04/09/2023
My screen was abruptly getting black
After that I started getting green line on my display
Now my screen has turned black and I am getting green lines on my display
Is there any bug in latest update?

Note: touchpad seems to be working as I am able to answer calls by swiping however display is black and is showing nothing

there does not seems to be any customer support number which can guide me through process. 

Can someone help me through what should I be doing as this is my primary device and I need it to be usable as soon as possible
