If you’re still on the Samsung Galaxy S3, and want the best that Android has to offer, then it’s no longer going to do you any favors. It has reached its dead-end, so toss it out and get a new device. Don’t even use it as a backup phone.
Because when Android 7.0 Nougat arrives, Android 6.0 Marshmallow will be old news along with the handset models that aren’t able to receive any newer versions.
This applies for official over-the-air (OTA) updates as well as flashing any custom ROMs.
Despite how popular the Galaxy S3 still, and how a lot of its users have tried to keep its software up-to-date, chances are there’s no way the next Android version could be supported by a four-year old device.
Heck, even Marshmallow was initially believed to be one step too far for the old 4.8-inch flagship, before indie developers managed to get it working with the 2015 update. Would the same happen for Nougat? We certainly don’t think so.
