OnePlus begins to push Oxygen os 4.0.3 software update for Nougat 7.0 powered Oneplus 3 and 3T smartphones. Currently both handsets are running on Oxygen os 4.0.2 which was released in January. The changelog for this update posted at OnePlus official forums. This firmware update adds new WiFi IPv6 toggle for this device. The download size of this update is 92MB. It also includes enhancements and bug fixes like fixed crashes for line, improved camera app stability, tweaked night photography exposure, updated smart wifi switcher, pre-installed Amazon Prime for India, update APN settings for carriers and enhanced audio recording quality.

If the user suspects WiFi disconnection after updating to newer version try to turn off IPv6 option in wifi configuration. The company now rolling out this software update through OTA.
