With a rooted mobile ,Can I free up some internal storage (ROM) after delete some google apps from system. After deleted that's apps is there any problem to other google apps like play store, google ply games and other apps in my system ? . is there any problem to my phone or system ?
No. Deleting apps from the system does NOT free up usable space. System applications are stored in the /system partition which is not usable space to the user, you will not gain any usable space this way.
