Samsung is rolling out OTA updates to Galaxy Note 5 and S6 Edge Plus with build numbers N920TUVU2COJ5 and G928TUVU2COJ5, respectively.
As per the official changelog, the update brings support for Gear VR to both the devices along with security patches and various bug fixes and improvements.
In case you don’t know, Samsung Gear VR is a virtual reality device by Samsung, in which you can put your Samsung device and see videos, movies, etc. in a fully immersive theatre like experience. The COJ5 update brings support for Gear VR to T-Mobile Note 5 and S6 Edge Plus, but to take benefit of it, you need to purchase the Samsung Gear VR separately.
The updates are already on the roll as we speak. If you haven’t received the OTA update notification yet on your T-Mobile Note 5 or S6 Edge Plus, go to Settings > About phone > Software updates section and manually check for the update.
For the rooted users, we wouldn’t yet recommend to install the OTA update to either of the devices. Chances are good that the OJ5 OTA update will break root on your T-Mobile Note 5 and S6 Edge Plus.
If you care about root access, we’d recommend you to wait for the folks over at xda to confirm if the newer builds are easily rootable with the previous rooting methods (custom kernels), or a new custom kernel will be required for the latest build. If a new custom kernel with SELinux set to Permissive is indeed required, then it’ll be better for you to wait for the developers to build one before install the OJ5 OTA update.
