R. Dave T. , via OnePlus 7 Pro Mirror Gray , Sep 13, 2020 : I have the T-Mobile version OnePlus 7 Pro model gm 1915 on 10.3.4.GM21AA. I believe TMobile must have two different variants of the OnePlus 7 Pro. Last month about 8/10/20 the OnePlus 7 Pro got an update version 10.0.6.GM31CB with August security patch. It is 9/12/20 and i have still not received this update. I am on the July security patch. I can't find much information on my version of the phone. Do you (OnePlus) or anyone else have any light that you could shed on this situation. I freaking love this phone and appreciate all of your help. Thank you guys. Dave T.
