OnePlus 3 has been relegated in less than a year to a secondary plane by having presented the OnePlus 3T, an updated version in hardware that stands out for its Snapdragon 821 chip that promises greater efficiency and performance at all levels. The reason for stopping selling the first is because we are dealing with a company that has to take steps very well taken due to its few years of existence.
Now, those users who have the OnePlus 3 will be able to upgrade to Android 7.0 Nougat just as users of Sony's Xperia X Performance are doing, although the latter already has the update officially. This is a "yet to be finished" version of OxygenOS based on Nougat, so it lends itself to being used by those who like the adventure of dealing with different bugs until the final version is found for everyone.
In order to get the update now, it will need to be installed manually When downloading the ZIP file, then follow the instructions that you can find from this same link. The update was announced yesterday from the OnePlus forums.
The beta build includes a new notification design, new design for the settings menu, a multi-window view, ability to replicate directly from notifications, support for custom DPI, added options in the status icon, added shortcuts for third-party applications and has been improved the personalization itself, among other things.
Being a beta, as has been said, you could find some problems with the compilation, such as Android Pay does not work properly and stability and performance were marred by some bugs. Anyway, with the amount of news, surely it will be difficult to resist that open beta of Nougat for that great OnePlus 3 phone.
