We have already posted about the Oneplus development team pushing the official Android 4.0 Nougat for the OnePlus 3 and the OnePlus 3T. Due to some bugs in the official OOS 4.0, the development team has now rolled out Oxygen OS 4.0.1 onePlus 3T. As the two flagship devices need to be released with the same Android OTA version, the manufacturer has now released the update for OnePlus 3 as well. However, not all regions may receive the OTA update at the same time. The Android 7.0 Nougat firmware will now show Oxygen OS 4.0.1 for OnePlus 3/3T.

Apart from the Oxygen OS 4.0.1 version, the new OTA update brings minor, but critical, bug fixes like the network issue, battery drainage issue, and some stability fixes. One of the major fixes is for the proximity sensor. The OTA update file weighs only around 36 MB for OnePlus 3 and 38 MB for the OnePlus 3T. Currently not much is know about the update as it is a minor bug fix update, but it may possess the January security patch level as well – that Google released this month.

The Open Beta 10 for OP 3 and Beta 1 for OP 3T, on the contrary, are quite stable as per our experience. Moreover, OnePlus is looking forward to releasing the Android 7.1.1 Nougat with the next Beta update and most likely will be named Open Beta 11 for OnePlus 3 and Open Beta 2 for 3T.

Update: OTA update zip and Full ROM zip for Oxygen SO 4.0.1 now available for OnePlus 3 and 3T. Download now.
