The thing is that I'm fed up of some stock adware apps on my Micromax phone and want to disable them for good. So, as per this answer, I used adb shell to disable the app, but I'm getting the following error:
shell@Q4260:/ $ pm hide com.micromax.trendingapps
Error: java.lang.SecurityException: Neither user 2000 nor current process has android.permission.MANAGE_USERS.
1|shell@Q4260:/ $
The error message indicates that I need android.permission.MANAGE_USERS to achieve that. So I even tried granting that permission to the shell app, but no use!
shell@Q4260:/ $ pm grant com.android.shell android.permission.MANAGE_USERS
Operation not allowed: java.lang.SecurityException: Package com.android.shell has not requested permission android.permission.MANAGE_USERS
1|shell@Q4260:/ $
Is there any other way to get myself that permission?
Finally, the smart-phone is Micromax Q4260 running Marshmallow if that matters. This could probably be solved by rooting, but I don't have any intention of rooting as it could be risky on this little known model.
