I got my phone back from the police after it was seized in a search warrant. After starting the dev tools on android an app showed up called ADUI, its a brute force scanner with the Cellebrite logo on it, and in the debug options this app is in there as one to use. Also, the recovery partition is not the same one that came with the phone, its the Hong Kong version. From skimming the manual on Cellebrite it mentions clearing any client apps from the phone. It appears like forensics have made a pretty rookie error to me, or is there another explanation?
