Which version of Android is it designed for?

I tried it on my Oppo Find X9 Pro with Android 16 and it gave me a security error message. Then I tried it on a Realme GT 7 Pro with Android 15 and it was the same as the Oppo. I tried it on a tablet I had at home with Android 14 and it still gives me a security error. I'm thinking of getting an Ayn Thor with Android 13, but I don't know if it will give me the same security problem. That's why I'd like to know which version it's designed for, or if I have to tell Android to ignore the error.
