OnePlus 3T on O2
O2 is the only operator in the UK stocking the OnePlus 3T O2

OnePlus has started rolling out the OxygenOS 3.5.4 update to OnePlus 3T users marking the device's second software update since its release. The update, however, does not bring Android Nougat elements.

The company took to its forum to announce the rollout and talk about the changes brought by the update. Some of these are:

  • Optimisations for T-Mobile users in US
  • Reduction in lag time when battery is below 5%
  • Enhanced Bluetooth Connectivity for Mazda Cars
  • Optimised Battery Saving Mode: Now GPS and Orientation preferences will be restored when Battery Saving Mode is off
  • Flashlight Issue in WhatsApp has been fixed
  • System Stability enhanced
  • Various Bug Fixes

The update mostly brings fixes and bug improvements with no new feature as such. This indicates that this may be the last of the OxygenOS updates to be based on Android Marshmallow.

Earlier this month, OnePlus 3 users experienced some features of Android Nougat on their devices as the company rolled out the first beta version of OxygenOS based on Android Nougat OS. The Chinese smartphone maker which has been criticised for its rather slow pace of update rollouts, started the beta program a few months ago to let users experience new OS features in its testing phase it self.

Although the OnePlus 3T was released only recently, the OnePlus 3 has been the first device to get this update. The company, however, mentioned in November that OnePlus 3T devices will surely receive the update by the end of this year.

OnePlus has is own custom ROM, the OxygenOS, which is based on stock Android experience while incorporating its own tweaks.
