The much touted, affordable, flagship killer phone OnePlus2 was being bogged down by a "not so refined" Oxygen OS. Thankfully, after a long wait - Android Marshmallow 6.0.1 based OxygenOS 3.0.2 update for OnePlus2 has started to rollout for users now via OTA update in a phased manner.

"This update is packed with new features and enhancements. One thing to note is that this update will clear your stored fingerprints. If you have fingerprint authentication setup, you will need to re-enroll again before use."

Here are some of the highlights of this update:

• 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

To manually check for the OTA update, Just go to Settings > About Phone > System Update
