How to remove apps which doesn't allow uninstall option without rooting smartphone? I'm using Samsung J7Max recently I updated MY AIRTEL app and try to uninstall it app uninstalled but leaves an duplicate MY AIRTEL app which tell me download MY AIRTEL app from playstore. I can't remove it or disable it. Don't know what to do. Here is snapshot of duplicate Airtel app.
From what I understand :


MY AIRTEL is a system application that's installed in the /system
partition
Updates to this app are stored in the /data partition


Without rooting your phone, you only have read access to /system, and read/write access to /data. That's why you can uninstall MY AIRTEL updates (which are in /data), but not the app itself (which is in /system). And since Google Play has a newer version, you'll be prompted to update it again, etc.

Rooting your phone will allow you to gain write access to /system and hence uninstall any system application.
