A friend of mine asked me for help, she currently uses a Samsung phone with android 5.1.1 and misses settings for virus security and cpu in the main settings UI. The "virus" alert should be something with red/yellow/green indicators, she said. Also there should be some settings concerning the operationg system. The change happened during an upgrade I guess.
I cannot figure out what she is speaking about, I have been using a Galaxy 2 and 4 up to now, currently running with 5.0.1
Do you have any idea what I could search for?
I also like to ask if you know an app (no root) for these security issues!?
