There are literally dozens of bug fixes coming soon to KitKat 4.4.2 users. When the Android KitKat 4.4.3 update is released by Google, (hopefully sometime during the month of April 2014), it’s expected that it will fix certain bugs and address other issues that have plagued users of KitKat 4.4.2 for several months.
To cite just two of the bugs that we've gotten e-mails about, in Android 4.4.2, Skype and other apps continuously try to access the camera. This has caused the battery to drain too quickly, and has resulted in low performance. Another bug has caused strange things to occur once the battery was charged to full, or when a low battery alert at 15% or 25% appeared, forcing the user to reboot his device to get things back to normal.
So be patient everyone. Relief is almost here.
