I have had OnePlus since beginning and now have 9 Pro. Also my job for 4 years was to test 5G phones. Trend has been pretty bad since 8. Since then (5G) sw( firmware and Android patch started to have problems and now with Pro 9... this phone has become annoying. One Plus 7 was great phone and it still is, my wife has it. But 9 Pro, stalls, goes black, does not respond to touch, refuses to connect to wifi, looses 4G/5G and overall it needs maintenance almost once per day. Most annoying thing has been loosing keyboard and its not coming back until restart. Sad to say but this is where my journey with OnePlus ends. To much Oppo and too less opensource and Android.
