I have installed drfone on my pc to try and recover a picture and since then I get this message. I have galaxy 7s edge with Android 7.0. It was not installed on the device itself. I tried to reset to manufacture setting - also didnt work.
What can I do? And should I try and do anything myself or take it to a lab?

Sorry - I have posted this before but only now registered so I can reply to those who answer me...
