The T-Mobile OnePlus 6T is now getting an update to version A6013_34_190116. The update comes in at 103.6MB and includes the December 2018 Android security patches as well as an unspecified dialer improvement.
T-Mo hasn’t yet updated its OnePlus 6T support page with info on this update, but TmoNews readers Nick and Dodger Brooklyn received the update earlier today. If you haven’t yet gotten the update on your OnePlus 6T, you can check for it manually by going into Settings > System > System update > Check for update.
Once you do update your T-Mobile OnePlus 6T, be sure to let us know!
Thanks, Nick and Dodger Brooklyn!
