Disable the Google OTA updates completely My android device is rooted and I would like to disable the Google OTA updates completely.

I did following steps:


Installed Disable Services and allowed it for root access.
Opened Disable Services
Under System Apps, selected Google Services Framework
I found SystemUpdateService is already unchecked.
I checked it and again unchecked it, then I restarted the android device.


However I see the notification for System Update. For its temporary resolution, I unchecked the notification of Google Play Services.

Please help me to disable the Google OTA updates completely

Sometimes it's put in 

settings > about phone > software updates > turn to manual updates only
