I recently applied for a repair for my aging Galaxy Note 9's battery, and the service we use that does that decided to replace it with an S23 Ultra, which is actually a mostly very nice handheld. However, it lacks two things that I found crucial with my old Note: an SD card slot and a headphone port. Ultimately it winds up being less than ideal as a media player, at least for local storage. Of course since a lot of my music is on a NAS, it's not a terribly big issue, but I like having at least some local stuff in the event of, say, a network outage while I'm away from home. The headphone port is more of an issue not only because I prefer the sort of $10 earbuds that you can get from, say, Panasonic et al., but they're also the antenna for receiving FM signals, which the Note 9 could do and the S23 Ultra can't.
Enter the small and not that mighty but perfectly functional Mechen H1 media player. It's 3.5", runs Android 6, has an SD card slot, and has a working FM receiver. I don't know much about the CPU other than the fact that it's 4-cores and 1.3 GHz according to the It's my new tinkering device.
One of the advantages of it running android over other media players which don't is that it's actually quite customizable. You wouldn't think it at first, though, as it's one of the rare android devices on the market that has basically no sign of Google anywhere on it, so no play store, no account integration (drive doesn't exist). All that's there is Chrome. But you can still enable developer mode and run adb stuff with it, and that's what I did to get the above programs installed. Because so many Google libraries are missing, trying to install Google Play is not a trivial task, and so I'd rather just push individual apps this way instead.
Yes, putting S4E1 on a media player is pretty silly, but the S23 is a bit too new for it now, and while it mostly runs it fails to play sound. It's also a game that resists most attempts to play it in Bluestacks or ChromeOS w/ Brunch, as it tends to be terribly laggy. It was never a particularly compelling game on mobile but it's a unique experience, and I would still like at least one device that can play it more-or-less as intended. Arguably what I should be using is my LG Enact, but that's an Android 8 device that struggles to do just about anything else, and I would feel silly breaking out an old phone just for one game that I don't even like very much. Having it on an mp3 player isn't much less silly, but at least I can argue it's only there because I had room for it and to test adb install operations (note that if you do this you'll also have to transfer an obb file -- I copied both from the installation previously on my Note 9).
Since it does support Bluetooth, next step is to see if it can support Bluetooth controllers (I have no reason to suspect it wouldn't, at least). USB device support seems limited, and I've tried plugging in some USB drives and it didn't recognize them at all. Again, doesn't matter much as the main peripheral I intend to use with this thing is wired headphones.
