For a phone that was supposed to "kill" high-priced flagships, the OnePlus 2 seems to have taken its sweet old time in upgrading to the latest version of Android. Whether that has to do with a smaller development team over at OnePlus, or the idiosyncrasies of the company's custom "Oxygen OS" ROM, we couldn't say. But it appears that the wait is finally over: according to a post on the OnePlus user forum, the Oxygen OS 3.0.2 over-the-air release (based on Marshmallow 6.0.1 code) is heading out today.

This comes after no less than two betas, and after someone on the CyanogenMod team got tired of waiting and released a nightly build for do-it-yourself updaters. The details of the update were posted to the OnePlus forum, and it's mostly the same as it was in the beta: Marshmallow underneath and a few software tweaks that are specific to this phone and some of the partner software.

  • Android 6.0.1 Marshmallow upgrade
  • Enhanced Doze mode for better battery life
  • System wide performance improvements
  • Improved fingerprint sensor performance and recognition
  • New OnePlus Camera UI and AF optimization
  • MaxxAudio and Tuner have been removed. We have integrated with Dirac HD Sound technology for the speaker so you get a great experience without the knobs and dials
  • Shelf UX has been improved. You can now long press to edit a board
  • You can now lock apps in recents so they won't be cleared away. We've also added clear process in addition to clear-all for those of you who want a better control of background processes
  • Network operator selection will now stick to your choice so you don't accidentally roam onto unintended networks
  • Swiftkey update to 6.3.3

A OnePlus staff member says that 100% of current OP2 users should be offered the over-the-air download in 48 hours, so sometime on Tuesday. (That's assuming that you're still running the stock software, of course.) Compared to the leisurely pace of standard manufacturer/carrier rollouts, that's pretty good. Users should note that the update will wipe the phone's fingerprint authentication cache, so they'll have to set up the fingerprint sensor again.
