Checking Android devices for Originality


Hi. Is there a way like online originality testing system or application to check if Android phone|tablet|other_device has been 'tampered' with aka installed different firmware in secret with Odin or other app and|or action. I have suspicion that some device(s) could be "infected" but to make sure i need to check if firmware is original etc. and that none other flashing etc. is done in secret to spy or w/e.

Most Android devices nowadays have this built in - they issue a big fat warning (tm) if some inofficial firmware has been flashed.
Whether that is a guarantee against every kind of tampering, or in fact useful at all, I don't know.
But why on earth, and how, would you want to check that over a website?

In what way that warning operate? Even if it is official firmware?

That was not my point. I simply want to check if device(s) are clean..

Short answer: checksums.

And longer answer would be? I am simply curious if it is possible to do something similar to C.S.I. on devices at home on my own to see if tampered or hacked|cracked at some point aka 'infected'. Also maybe there is possibility to see hidden processes..ironically mobile devices have become similar to desktop devices aka in need of some kind of malware protection.

Something about locking/unlocking the bootloader. Your web searches. I'm not in the mood to do them for you, Android sucks.
But that's not a full guarantee that your phone hasn't been tampered with. I think on Linux such software exists, but has to be installed & running before the tampering occurs.
Android works differently though.

No problem. I was not requesting doing. Just asked for info. And if Android which is free and popular sux then what does not sux? Is there even choice? Either outdated buttonphone OS with limited funcionality or iOS or Android or MS..and with C.S.I. i mean doing experimentaltesting to see if other people who had access did not alter their factory behaviour to cause either harm or whatever.
