[Samsung Galaxy Star] sukucorp:
All,

I have a rooted GT-S5282 with Android 4.1.2. I keep the phone for backup in case primary phone has a problem. It is also occasionally used for media playback.

I wanted to trim the phone down so that the performance can be improved (both battery and speed). After a detailed research on the "Internets", the following are the apks that can be retained/removed/added. Few of the apks are frozen just in case they are required in future but are safe to remove if you do not need that functionality.
