Download Oxygen OS 4.0.3 for OnePlus 3 and 3T OTA and Full ROM how to install

Update: OxygenOS 5.0.3 is now available for download for OnePlus 3/3T. The break is over and the OnePlus development team is back to work. The very first thing the development team has deployed is the Oxygen OS 4.0.3 OTA update for the OnePlus 3 and the OnePlus 3T. The new Oxygen OS 4.0.3 is a huge update with some highly demanding bug fixes and stability improvements. OnePlus users were unhappy about the Nougat update and the firmware being too heavy on RAM and battery life. However, that is in the past now and with Oxygen OS 4.0.3, the WiFi has been optimized, increased camera app stability and RAM consumption have been decreased significantly.

The Oxygen OS 4.0.3 also optimizes the exposure while taking photos at night, some Audio parameters improvements, updates APN settings, and the brand new Amazon Prime app pre-installed. It is not known whether the update holds the latest February 2017 or the January 2017 security patch level. This also means the Open Beta 12 is on the way – an update over Open Beta 11. So stay tuned.
