How to get rid of spying app (rooted) My android phone is installed with spyware (spying app). This can be a breach for my business leaking out passwords.
How to clean wipe android OS and freshly install Android OS again cleanly.
My system is rooted.
Phone Model : Samsung A7 2018.
It's called &quot;flashing the stock ROM&quot;.  Look for the firmware for your particular model (N, FD, etc.) at https://www.sammobile.com/  There are pretty good instructions at https://www.getdroidtips.com/samsung-galaxy-a7-2018-stock-firmware/
(If you still want the phone to be rooted, you'll have to root it again - the stock ROM isn't rooted, it's what you got when you first got the phone.)
