I don't have an App I must use, but some people do. The Play Integrity API is annoying. Does that happen with AOSP, because if it doesn't couldn't a non-GOS AOSP just be virtualized when needed to get around this? There are old phones with less power, can't 1/8th of the phone CPU and RAM be allocated to mimic such an older phone or tablet?
In a better situation, this wouldn't be needed, but would this be a workaround? I am not good enough at understanding development and hardware to know if this could be done.
