This is a common problem with all android phones. But some users have reported that the battery life became poor after installing this 4.4.2 version. It can be controlled by regulating the usage of apps. Some apps need to be deleted. Also you can fix it by doing Factory Reset.
Performance lagging is the other Samsung Galaxy S4 Bugs Since 4.4.2 Upgrade. Performances got delayed as a result of this upgraded version. Though Factory Reset will remove all the data but still this is the only option to recover the Galaxy S4 performances.

Haphazard contact list
Messy contact list is another Samsung Galaxy S4 Bugs Since 4.4.2 Upgrade that most of the users are complaining about. This bug can be fixed in two ways.
