If you ask me: Which new brand's smartphone gets regular software updates? The immediate answer from me will be 'OnePlus'. Ever since the OnePlus 3T release, the Chinese vendor is betting big on the software updates department. The OnePlus 3 and 3T users received Oxygen OS 4.0 update based on Android Nougat on January 1, 2017.
After that, OnePlus has updated both the OnePlus 3 and 3T for nearly five times fixing most of the bugs and adding new features. Recently, OnePlus announced the OxygenOS Open Beta 4 for both the OnePlus 3 and 3T users, and the surprise was the addition of new features.
If you look at the changelog closely, OnePlus has added a new feature: Secure Box, which locks your files, photos, and other media files by setting a PIN code or pattern, same as what Samsung is offering with the Samsung KNOX. The company has also introduced Quick Pay to help the people from demonetization. A special DND mode while gaming will help most of the users out there.
All said, the Oxygen OS will soon become a feature rich OS, which was once known for its stockish Android UI.
