Interesting idea leveraging a cheap Android. I wonder how difficult it would be to modify an instance of a regular headless browser in order to convince a website you're using an Android browser. Not sure if Androids just come with mobile Chrome these days or if OEM/carrier-developed type stock browsers still get shipped.

Also totally right on the IP reputation point. I saw a post on HN in the last few months of someone describing how they used a cheap mobile data plan + USB LTE modem to proxy their web scraping. I believe you get effectively treated as a residential IP (depends on the complexity of the system - if they're simply blacklisting datacenter IPs then this should work) with the additional benefit of being able to change the IP assigned to the modem easily.
