I have identified a root folder(not rooted) with what appears to be a next os in a fused file system in system storage (access denied) it’s now been found in all my current an old devices. All with different date of breach, all were well protected. Tried everything paid an free nothing ever detects or prevents. Factory reset does not remove vcl debugging has shown some I didn’t know, microdns, services listning to tcp ports I also have one pixel cell never activated no sim with fused files system tho never set up in it’s devolper options found cloud storge app started one service cloud sign in been running 44 hours? Same as others I’ve found all have some same files created at same date time of breach. Mraid mbridge700? Native bridge? Anyway how to remove and if possible prevent.. please advise
