If you're genuinely interested in continuing and have some funds AND run PC, AMIDuOS LITE (SPECIFICALLY LITE, Pro doesn't work) can run Unchained. It's got a 30-day trial to double check that things
do in fact work (I checked it out about a month ago and it was still fine), and it's $10 to buy a license after that. If memory vaguely serves, you may have to download the apk via qooapps (
https://apps.qoo-app.com/en/app/3854) as I think it doesn't show up in the google store? (Though they might have been on the PRO version, my trial's out so I cannot double check. :'I )
A fair amount of effort, but fairly worthwhile! Especially if you don't see your grandmother that often.
