Install F-Droid and IzzyOnDroid repos and you can use it for whatever you find there. I use mine as an alarm clock, note pad, music player and spare camera around the house. Sometimes a browser (wifi) but it's a bit old. I thought about putting all my recipes in text format and using it as a cookbook as well.

I like having offline apps on my old android phone. Such as the Kiwix app with offline wikipedia, Organic maps app with downloaded maps, Readera app with some epub books.

Load it to the brim with literature pdf's, put in a faraday box incase an nuclear EMP or those monster solar flare things takes out all electrical components. I'm not a doomsday prepper or anything but did this with an old 256gb phone for shits and giggles. It's absolutely insane the amount of text documents 256gb holds lol

When I went on vacation, I left my phone behind and took along an old smartphone with no sim card. I used the smartphone as a camera. It still received a GPS signal and I loaded off-line maps so I could use Google Maps. When I was at the hotel in the evening I checked my email and looked up local information with wifi and played games on it. But work couldn't call me, which was nice.

In case you own a lot of devices with remotes, you might transform it into a universal remote with an USB C IR dongle. Wouldn't be my first choice as you'd still need to recharge it so often but I read of such projects.

Alternatively, you could give it to children for gaming and watching videos. Children are anyway mostly on WiFi and if you equip it with some emulators and ROMs they'll have tons of funny games without all of these toxic in-app purchases, ads and casino mechanisms.

The most common thing I’ve seen are projects where it acts like a screen or control panel on the wall. Something that’s a fixture or art project.

You don’t need it for anything like music or games - your new phone will be more convenient and run those things better anyway.

A friend of mine stuck an old tablet on the wall and connected it via Bluetooth to his keg system. It gave him a permanent status readout on his beer temperature and how much was left in each keg. It just had a power cable plugged in all the time so it didn’t need to be charged.

Bicycle or hiking computer. With osmand and organic maps you can get your position from GPS without a sim card and use the phone for navigation, trip recording, stats etc.

I use a Pixel ~~6a~~ 4a I had laying around as a dedicated Discord device, paired with a bluetooth headset. Now I can chat with the lads while around the house doing chores.

i have bad luck with phones so i go through them faster than most so i always the the $100 androids.

in the past i've used them as ip cameras as part of a homemade security monitoring systems using motion; car dash cams; car backup cameras; homemade lojack; car stereo screens; parallel parking sensor aides; secondary alarm clocks; intermediate android auto proxies; backup alarm clocks; and secondary phones for applications/control that my employers have mandated; system interface screen; bathroom readers; usb drives; wifi extenders; and remote controls.

Donate it. I'm sure there's someplace that will want it as a wifi-cabable minitablet for kids to access the Internet on.

You can try to see how far you can skip it on a lake or pond.

I've had my phone for at least 4 years but it runs well,

What's the exact phone model? I'd be really surprised such a phone wouldn't support LTE, 5G was about to come out 4 years ago. Even the OG pixel should support LTE. Unless your issue is lack of VoLTE support, which sometimes can be remediated with root or custom roms. Although I find the Internet portion to be more useful anyway, as you can just route the calls over regular VoIP and use Signal or Matrix or Discord or whatever.

Unless it's a Samsung, then you're kind of SoL into the fix by modding department, you're stuck with what regular Android apps can do.
