While the OnePlus 3 and 3T are apparently set to receive their updates to Android 7.0 Nougat before this year is over, the same probably can’t be said for the OnePlus 2. Last year’s flagship from the Chinese upstart may taste Nougat itself, but the day when that happens isn’t today.
Instead, owners of the OnePlus 2 will be getting a new update based on Marshmallow, namely OxygenOS 3.5.5. This has started rolling out incrementally, which means the over-the-air update will reach a small number of phones today, and a broader release will follow in the next few days.
The new software version comes with the December security fixes, VoLTE functionality enabled for some carriers, App Lock, Battery Saving Mode, Gaming Mode, additional options for the Alert Slider, a new design for the volume adjustment bar, Shelf optimizations, increased system stability, and the usual unnamed “general bug fixes”.
This also introduces the new OxygenOS UI to the OnePlus 2, along with an updated UI for the Clock app. Google’s Clock, Calculator, and Messages will be replaced by stock OnePlus apps if you’ve never updated them. If you like Google’s versions better, you can always download them from the Play Store afterwards.
OnePlus notes that many of the phone settings will be reset to default after the update – the device name, ringtones, accent colors, and status bar battery indication.
