Hello,
My One Plus 8 pro is stuck on black screen and my not able to boot it again. I tried to hold power button or power+volume down for 10 seconds and nothing happened. I also try charging it, without success. I cannot remove the battery since the phone is sealed.
There is no particular reason for this black screen : there was no impact or water damage, it was working for several months, no recent upgrades (about 1 or 2 months ago).
Do you have any idea what could be the cause of this black screen ? And what can I do about it ?
