Original review below for comparison. Good hardware still needs good software and in this regard Oneplus have failed with their android 12 roll out. After 3 beta tests the stable release broke some essential features (like mobile signal...) And removed some existing ones (One plus have now withdrawn the update for further work). If you need a new phone get a pixel 6 or an S21 instead.
Old review: Good things (coming from an s20 ultra) -Latest Snapdragon chip -The matte finish on the back is better than shiny glass. -Fingerprint reader is very fast and much more accurate than my last phone. -Oxygen OS is close enough to stock android to use as is (sooo much better than One UI). -Supplied wired charger is superfast! -Camera is pretty good so far. I prefer not having super saturated photos as I did with the s20 ultra. -Comes with a case -Battery life is good, the phone lasts me the day. -Cheaper than a Samsung
-The whole throttling thing -Despite that it can get quite hot under heavy load. -One+ are apparently merging oxygen OS with Colour OS and future updates will be based on that. -Not much clarity on the number of OS updates for the device (Samsung are actually good at this now, how things change). -No SD card slot or headphone jack.
I guess I'm happy enough. I think the days of new phones surprising with design or new features are long gone. This is a good device with a few drawbacks that will nonetheless do very well for most people at a slightly lower pricepoint than its competitors.
