Recently, iFixit conducted a detailed disassembly of the OnePlus 9 Pro, and the final repairable score was 4 points (total score of 10 points, the higher the score, the easier it is to repair). From this score, the maintenance of the OnePlus 9 Pro is still relatively difficult.
The use of glue on the rear panel greatly increases the difficulty of disassembly (although this is good for waterproof and dustproof), and a large amount of disassembly is required to replace the screen. element.

A true standout of OnePlus devices in recent years has been the usage of high refresh rate AMOLEDs. This time around, the usage of an LTPO panel knocks things up another notch. The OnePlus 9 Pro can run at 120Hz at FHD+ and QHD+ resolutions, but this newer AMOLED has a proper dynamic refresh rate that can be set as low as 1Hz. This should have battery benefits, but I can’t say I even noticed it in action.
OnePlus also touts a 360Hz touch sampling rate, which again I can’t honestly say made majorly noticeable differences in my daily experience. The OS and 120Hz refresh rate are pretty sublime, and this is among the best displays I have used to date. It could even be the best smartphone display out there if only the Find X3 Pro hadn’t hit the market first.
I quite like curved displays – aesthetically I feel they look sleeker and in terms of usability – and it’s an area I haven’t had too many bad experiences. But having switched between the OnePlus 9 and 9 Pro, and my default Pixel 4a, I think I am starting to lean toward flat displays more predominantly. I’ve found that cradling in my right-hand means I’m obscuring much of the bottom-right of the display.
