Phone info setup as a device administrator
I have had my phone for a while now, but today was the first time since I got the phone that I looked at the device administrators area (settings / security / device administrators) and I noticed that there was an item called "Phone Info" that was activated by default and after reading about what it is supposed to do, I decided to deactivate it, but I was unable to do so. My questions therfore are:
1.) what is the purpose of this item?
2.) why can I not deactivate it?
3.) is it normal for it to be activated by default?
4.) if is not needed than how do I get rid of it?
In case it helps, my phone is rooted and I am still running the stock 4.1.2 ROM that came with the phone.
A few days ago I tried out the "All In One" 4.3 Stock ROM from Thunder Stick, but it was not working for me to well so I restored my nandroid backup of my original stock ROM so I am not sure If the other ROM has anything to do with it or not or if the setting has always been like that, but as I said before, I just noticed it today and would like to know what it is and how to deactivate it if I can.
Thanks for any and all replies,
