OnePlus has rolled out another small but significant update to OxygenOS 4.0 for their OnePlus 3 and 3T. The update bumps the build up to 4.0.3 and contains a number of bug fixes and patches. Two of the items addressed in the release have to do with Wi-Fi, with IPv6 now supported and an improved Wi-Fi Switcher. This feature will switch your connection over to data if your Wi-Fi signal is consistently poor.
The camera app has also been updated, increasing stability in the app according to the release notes.
