Hi guys I have an android running custom rom on 8.1 . I found this problem when I was downloading files from ANDROID DOWNLOAD MANAGER the speed shown by ADM was very less in comparison to that shown by INTERNET SPEED METER LITE( which I think is good app because of having 10 million downloads) ,to find the culprit who was using data in background I got into SETTINGS
How can android system use so much data of 691 MB(remember its not play services or any useless google apps since I have only pico version of gapps installed)
I run my net on mobile data where I get 1GB per day , if i am getting 641 MB robbed How can I stop it without affecting my Android and is that possible that Cistom rom developers may add some Traffic Bot or Cryptocurrency miner bot to my Android and name as SYSTEM APPS.
