I kept my old phone (an AT&T-locked Samsung Galaxy S7) going for 10 years, replacing the battery midway through and using it well into unsupported territory. I like to keep things working as long as I can within reason, and I also know that this phone is destined to become e-waste as soon as I get rid of it.
But with more apps losing support, and electronics prices on the rise, it felt like now was finally the time to upgrade (to a refurbished Pixel 8 Pro). So I got a new phone…
Still, I don’t want my old locked Galaxy S7 phone to go to waste just yet while it’s still roughly working!
So does anyone have any idea of things that I can do to reuse or repurpose my old phone?
I have some ideas in mind myself, but I’m curious what you all think and if anyone has experience with repurposing old phones in interesting or useful ways.
turn it into a webcam with a little web server thing on it so you can look at it and watch it freeze all the time because it actually kind of sucks
When I worked in skilled nursing I had lots of patients who loved to listen to music. Fewer and fewer families had radios or cd players to give them. Perhaps donate it to a skilled nursing facility loaded with Elvis and Neil Diamond mp3s

I put LineageOS on my old phone, put adblockers on it and added a few streaming sites to the home screen and gave it to my parents to use as stream caster to their smart TV. They freaking love it. “How is this free?! We’re cancelling Netflix!”
A lot of streaming sites are getting shut down left and right, sadly.
Pipboy!
A Galaxy S7 is still fairly powerful. It should be able to do everything a phone does. Put LineageOS if you need a more recent android version. Are you on a bootloader permalocked variant?
Dedicated mp3 Player?
Personally I prefer to give mine to charities that help women escape domestic violence households and need help setting up their lives again. Many leave with nothing, including their phones which are usually being tracked by their abuser. Have a look around to find one, or a local homeless shelter. Or, if you’re worried it will become ewaste, send it to a recycling centre - many parts can be stripped out and made into new products.
Use it as a security camera.

Just be aware that Media Monkey has issues. It regularly swaps my track numbers for the play count, and has consistently lowered the volume of my tracks.
I used the volume leveling function, and found out that it was decreasing the volume of all the tracks it had access to. Luckily the originals on the computer were unaffected
Weird, it’s never done anyting like that for me.
I know it gas some volume leveling options, though I’ve never used them, and I’ve used it for what seems like 10 years.
It’s definitely not perfect - getting sync to work can be a challenge.
you could always use it for some tech experiments! there’s lots of examples out there. retro gaming console, home server, run your own AI model (at least better than using big tech!), etc
run your own AI model
What AI model could you run locally on a decade old phone though? Probably nothing too sophisticated. It would have to be like ChatGTP 2 or something which doesn’t do a great job of holding a conversation
I’m more suggesting it as an experiment, not a full force state-of-the-art agent. Could be a great way to learn a new skill
I always just hang on to them in case somebody breaks or loses theirs.
By the way, I’m all out of old phones and my son’s is busted, so if you don’t know anyone who could use it…

I used an old phone with a broken screen as a webcam since covid untill it totally broke recently.
However it needed some stars to align; I had a 3D printer to make a custom holder so it could sit on my monitor unobtrusively. I also luckily had a phone with a built in method to limit the battery charging so it could be plugged in 24/7. I was able to disable all power saving and permission features, so the app could run 24/7 without being killed by android.
I used droidcam, which works with an OBS plugin nowadays. I got it to the point that I just needed to launch OBS and my webcam was on, no touching or fiddling with the phone at all.
Emulator game portable -
install an emulator, load it up with literally every game from atari to gameboy advance , and snap on a phone-attachable controller
