How to disable DRParser Mode to use mobile data I have an Samsung A310F with Android 7.
I switched off "mobile data using" but every time when i turn on the phone or restart it, the "DRParser Mode"(System application) use my mobile data.

How to block, disable or remove this app?

Thanks for help

There are two apps that you can use to disable unnecessary packages (and in this case DRParser Mode) .

These are Package Disabler and Adhell. Both apps list out all the apps and services installed on the device and let you disable or enable them with a single tap. Most importantly it’s completely reversible and no root is required.


  Adhell is a Free, Open Source Ad Blocker with Package Disabler for
  Samsung Devices, while Adhell is free while Package Disabler costs a
  little over $1.
