After the final update the subject problems I am facing, which is really annoying.
I tried many solutions such as soft reset, hard reset, clear caches, but I can only say that the update caused these problems together..
Information of my phone are attached.
This link shows how you can downgrade your android version. I cannot guarantee that this will work. its worth a try if you really need to use your phone like before.
Thanks, but Samsung shall be responsible of not providing uninspected versions to us. NFC was a crucial tool for me and it was the only reason I bought the phone, and the battery issue is making my life miserable. I would sue Samsung if things are because of the unverified software release and I will make sure to keep the phone software as per the warranty condition.
