The description of System App Manager
Root is required.
Now even paid apps can be converted to system apps!!!
Lollipop is supported!
New "safe to uninstall" reporting feature!
System app manager, is a small and powerful application.
App manager works as root uninstaller, root manager, system cleaner, bloatware remover.
You can backup your application data, and later restore it (some apps needs the device restart to work after restoring)
Clean application cache and dalvik-cache.
All this in about 500 kb of application size.
If you have problems with some of the functions, please try to update busybox,
if still not work, contact me.
App manager let you manage all applications that are installed on your device.
Move your preferred applications to system, uninstall unwanted system applications and bloatware,
freeze (disable) applications, move applications on the external storage (sd card) and back ( on some devices it will not work)
backup and restore app data etc...
before uninstalling system apps, disable them, test a day or two,
then, if all is normal, proceed with uninstall.
Do not manage system apps that you are unsure of its purpose.
