Oneplus has released OxygenOS 3.5.4 community build for OnePlus 3. Based on Android 6.0.1 Marshmallow, the new build comes with various optimizations and improvements in several key areas of the OS, besides general bug fixes. Though the OxygenOS 3.5.4 update comes with a few new additions, the main goal of this community build is to improve the performance and frequency of updates.

If you have joined OxygenOS Beta program and running on the previous community build (OxygenOS 3.5.3), you will receive the OTA (over the air) update for the new update. Other OnePlus 3 owners who want to try out new features of the community build can download the full firmware and flash it manually via ADB.



What is new in OxygenOS 3.5.4 update:

– Added new App Lock feature

– Fixed key guard crashes when enabling SIM card lock in multiple languages

– Optimized accent colors in default themes

– Optimized translations for certain languages

– Improved the quality of expanded screenshots

– Increased system stability

– General bug fixes

New owners of OnePlus 3, who would like to install this community build, keep in mind that the ROM is a community build and testing version, so it is not ready to be used as a daily driver. Also note that, though you will receive future community OTA update for this ROM, you will not get official OTAs after flashing the community build. To get official OTA update, you need to clean install the stock OxygenOS.
