First of all I would like to appreciate samsung team for improving fingerprint sensor, now fingerprint sensor is very fast and accurate.
But on another side Samsung also said with this update also improve battery life which is not true, after August Update charging time have increased by 20-30 mins i.e now phone getting charged slow. And coming to battery life very poor backup.
Before update 1hr:40min 100%
After August Update 2hr:10-20min 100%
Samsung now you should really work on this and should decrease charging time and increase battery life.
