What Mobile Operating System Do You Use?

Currently using jailbroken iOS on iPhone 7 while (still!) waiting for my Librem5

Brucehankins i've heard a lot of good things about the palm products but i never breached that gap myself

bja-au What do you find beneficial about jail breaking these days? I haven't done it for years, so wondered if it's still worth it?

Brucehankins I might try that at some point. I am waiting for such a project to mature.

LineageOS for microG

Stock Android for first MotoG from motorola, Android Lollipop...
"It's a phone, not a computer" as I like to say, I don't want phones to be able to do what my computer can, if it calls, has instant message like whatsapp(need for work and low cost calls), bank app, and wifi antenae to browse the web a little, then it's fine.
while, I have to admit, I use it for some e-books, prime user

Unmodified Android on a Samsung phone.

markdj There are a few jailbreak tweaks I use a lot, BioProtect (password/TouchID secure folders/apps), Dark Keyboard (still does a better job than Apple implementation IMHO), DeleteForever (tidy up pics), FiveColumnHomeScreen (as it says), Lockscreen custom text (I use it display how to contact me if phone lost), plus a lot of others. Contact me if you want a complete list with reasons

I'm currently on /e/ OS (Android with microG integrated) and I'm really satisfied with its performance.

Using LineageOS on an Xperia XA2 atm. F-Droid is very impressive. Even then it's a bit uncomfortable that it's a tracking device. Been considering getting a dumb phone that is at home all the time and use my Lineagephone only with wifi and no sim-card.

Could be fun getting another device to try out a Linux mobile OS at some point though.

Yep, I am recycling my trusty Sony Xperia Z5 compact with /e/ OS, it's an unofficial build of the OS but it works and it can be used degooglefied! Hooray!!

I'm using Android 9 (Notorious Samsung Galaxy A8, which bot updated up to Android 10) and i ressurected BlackBerry Playbook with BlackBerry Tablet OS and locked bootloader (no hack, no one chance to change dinosaurs system)

I use eelo os ungoogled Android. My personal nextcloud server is so well integrated !

I wish new solus mobile os my dream

fabiomorales9999 We are a desktop operating system. This includes laptops and normal desktop computers. Not server or mobile. Those platforms have very different requirements and would not be implemented at all like Solus.
