On the latter device, the patch comes with a bonus - apparently, Samsung's fixed another bug that would prevent the device from charging beyond around 85%. This annoying issue was reportedly brought about by the Galaxy A3 (2016)'s Nougat update that was released earlier in the summer.You'll be able to do ~15% more of that on your Galaxy A3 (2016) now.
The build number to look out for is A310FXXU3CQI8, and it should be hitting Galaxy A3 (2016) units soon, if it already hasn't.
Galaxy A5 2017 has the same problem, and stopped on 92%. This seems to be the problem in other models as well as A3 and A7. Check it please.
Good update, now charging stops at 90% instead of 85%. Maybe 2 updates later also 100% is possible
I live in Europe and we still have Marshmallow in our phones despite Samsung promises of Nougat update months ago, whelp at least security upate is "only" 3 months old.
