OnePlus has started an incremental roll out of OxygenOS 4.0.2 for the OnePlus 3T device. The news follows the announcement of the software update to OxygenOS 4.0, based on Android 7.0 Nougat, at the very end of 2016. OnePlus, like Google, deliberately stage their software roll outs over a number of days and the main reason for this is that it allows users to test the software and provide initial feedback. If there are widely reported issues, OnePlus could suspend the software update. With the release of OxygenOS, it appears that there were some problems with the device – namely the Wi-Fi radio, which OnePlus explains "might still fluctuate" even with this update – OnePlus forum owners are encouraged to private message the OnePlus staff member advising customers of the issue. Other issues include how the proximity sensor behaved during a call, and an issue associated with downloading from the Google Play Store, both of which have been fixed in the update to OxygenOS 4.0.2. Furthermore, OnePlus have improved overall system stability with the new build of OxygenOS. The software is being released to customers over the world in stages with OnePlus reporting that the rollout will start small. From activity on the OnePlus forum, it appears that the update has been made widely available in Canada so customers eager for the new version have been using a location-changing VPN to tell the OnePlus servers that they are in Canada in order to receive the update.
In common with Android 7.0 Nougat, OnePlus OxygenOS 4.0.2 includes several new features, including improvements to the Notifications system and the ability to directly reply. There's an option to modify the Status Bar Icons. Elsewhere on the device, there are improvements to the Settings screen and within the menu, a number of additions including the ability to switch to a custom DPI setting (a means of changing the look and feel of a device). For connectivity, OnePlus have updated APN settings for an undisclosed number of carriers around the world. The device also includes Google's multi-window view mode and improvements to power management, including the enhanced Doze mode.
OnePlus have promised to improve their software support and the company appear to have worked extremely hard in order to make their self-imposed December 31 deadline for releasing Android Nougat for the OnePlus 3 and OnePlus 3T. Now it seems that there were some issues, but the company has moved quickly to resolve these with a software update. As for the Wi-Fi connectivity difficulties, OnePlus is aware that some customers might still be experiencing the issue and has promised a fix – although it has not yet committed itself to a date.
