T-Mobile has patiently tested and failed Oneplus's rushed updates. Wisely they prevented buggy deviation being released on their subscribers. They just pushed a update a few ago with the new security updates. They are testing the later 12 updates and have found a dozen new bugs that are unacceptable. So we are still on 11. I hope OnePlus quickly resolves T-Mobile's detected flaws and releases an update for T-Mobile to retest. I appreciate not being saddled with bugs just to have the latest software. T-Mobile takes better care of their customers then most. I also appreciate the continually improving network conditions. The Sprint tower reworks and band adjustments have been improving service here but by bit. Keep it up and soon there will be more of us in Pink.
