My one plus 8 pro got progressively worse with every software update.
The three most frustrating bugs were the first 5 or so seconds of video recording being laggy and poor, the camera opening very slowly so you'd miss the opportunity to take a picture of whatever it was you were trying to capture quickly, and worst of all, the Bluetooth volume randomly going to 100% and deafening me.
Oh and Google pay kept randomly not working, which was embarrassing.
I was a customer going all the way back to oneplus 2, but after my last two phones, never again.
My oneplus 6pro's camera developed a bug that wouldn't allow anything in focus, and it persisted after sending it back to the factory.
My oneplus Nord developed a memory issue that would constantly save bug reports to system memory anytime you had 5g enabled. It would basically require a complete system wipe after the end of the day. Pretty sure they didn't even open it up when I sent it back for repairs.
The hardware is shit, and the customer service is even worse. I really can't believe they have the gall to charge people flagship prices for such shitty product and service.
I hated the android 12 update so much on my 8 pro, I ended up rolling back to android 11 and using the phone without security updates instead. Got a different phone now, and I won't be going back to OnePlus for a long while
