I haven't got to the running a node part yet as I'm waiting on a power-and-charge adapter/splitter doodad so I can plug it into charge and a USB3 SSD, but I just wanted to see if my motorola g51 running android 12 could do it.

Yes, install fdroid, install termux, run termux-setup-storage. But I couldn't figure out how to get at the external device, testing with a combo usb-a/c flash drive, and voila, finally got to it after this:

With this and a sleek 1tb nvme ssd enclosure it's just charger, cable, drive cable, drive, phone, all together not much space on a desk and a nice use of one of these annoying pocket sized computers, better than any other that I know of.

I'm thinking the logical thing to do once that's set up is put LND or CLN on it and hook up a control interface to it via a tor hidden service and you pretty much should be able to just plug it in somewhere out of the way and forget about it, until somehow something breaks and you have to restart it or something.

Very interesting to me as this is something I could see an Indra relay running on, any old phone with 2gb of memory and android 6+ should be able to do this, run channels off it, it's got built in battery backup that should keep it running for half a day and you can always chain up a battery bank for longer reliablity in bad power situations. Certainly, with a 20kmwh battery bank in a backpack it would run a couple of days on mobile and wifi networks. Not really terribly useful in this way but very compact for someone like me who might need to travel and privately access the chain data.
