My Samsung Galaxy Active Tab 2 has Android 5.1.1. and shows 'the latest software is installed' when I check for updates. However, the main app I use is OsmAnd and it no longer 'supports the device' which means I can't download maps etc. Apparently OsmAnd needs Android 6 or later to operate. Has my Active Tab 2 reached the end of it's capabilities or is there something I can do to update it to Android 6?
