Back in December, the Chinese company has released OxygenOS 4.0, which was based on Android Nougat and it rolled out to both the OnePlus 3 and 3T. The same handsets are now getting the latest OxygenOS 4.0.3 update, which brought many improvements and important bug fixes.
According to the official change-log, OxygenOS 4.0.3 comes with Wi-Fi IPv6 Support toggle, improved stability of the Camera app, optimized exposure when taking night time photos, optimized Smart Wi-Fi Switcher (when it’s turned on and Wi-Fi signal is consistently poor, device will automatically switch to data connection), updated Audio Parameters and improved the quality of audio recordings, updated APN settings for select carriers, Indian users will have Amazon Prime App pre-installed and Line app will no longer crash.
Users have been complaining about Wi-Fi connection issues and the company is still tracking them. If there are serious problems with either the OnePlus 3 or 3T, users are advised to head to Settings > Wi-Fi and tap on Configure Wi-Fi option from the top right corner. After that, they will scroll down to the bottom of the page, where they will check the IP address format. If it’s IPv6 based (multiple lines), then turning off the IPv6 Support toggle should fix the disconnection issues.
OnePlus has another recommendation for users who experience frequent WiFi disconnections caused by switches between Wi-Fi and cellular data sources. The problem should be fixed if the Smart Wi-Fi Switcher is turned off at Settings, then Wi-Fi is disabled and users configure Wi-Fi. If this method doesn’t work, users should describe the problem on OnePlus’ community forums. In addition, customers are able to give their feedback about OnePlus’ user interface in OxygenOS.
OxygenOS 4.0.3 update will roll out in phases, first to a limited number of OnePlus 3 and 3T owners, then it will be available to everyone else in the next two or three days.
