Unless you have the su binary on your device, you will not be able to change anything in /system/app or /system/priv-app
/system is mounted at runtime as a read-only filesystem - you would need to remount this as read-write before uninstalling app (which is just moving / deleting apks), and this can only be done as root
If it is already mounted (for whatever reason) you would still need to have a user that had rw permissions on the folders. /system/app & /system/priv-app are owned by root:root
(user apps are in /data/app, which is owned by system:system)
Is there a decent option to remove or at least freeze shitty vendor apps on a non-rooted phone. Titanium backup used to be my go to but phone needs to be rooted.
