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.
