I have a Doogee F3 Pro running Lolipop 5.1. Haven't rooted, just stock Android SAS supplied by Doogee. Can't access TV anywhere due to unauthorised Mods error/msg. Bit lame because I haven't modified it. Anyway round this?
Try turning the power off for the device and turn it back on after 20 seconds. Might as well get the simple fixes out of the way. You should check in settings to see if the device thinks its rooted. About device I think.
Is the message ‘The operating system on your device has been modified in an unauthorized way …’?
'Unauthorised Modifications Detected' error message comes up. Have done the obvious power cycle and looked for superuser apps on phone, nothing I can find. Guessing the stock Android 5.1 on my phone is a slightly modified one that Doogee put on their devices. Disappointing that TV anywhere app is so sensitive!
