One Plus 3t is Best Phone.But I updated my one Plus 3t OS to Oreo. Oreo isn’t that stable right now lots of people have are facing battery issues including me and some issues with volume so it is buggy clearing cache memory could be fix.No issue in factory resetting but it would be long process due backing up first and then restoring and preferably updates should not make us do that because that is essentially causing inconvenience.No problems with others suggestions just saying updating the phone should not be like that and I agree that some people don’t know how to use their phone.
New update comes
1 Added support for aptxHD
2 Added Wi-Fi Hotspot device manager
3 soft screen calibration
4 Update andorid security path to December
5 General bug fixes and stability improvement
Finally phone works good.
