List of stuff I tested with last tested Status (Copy of: https://catwithcode.moe/Blog/2024.10.07_Ubuntu_Touch_on_Fairphone_5/Ubuntu_Touch_on_Fairphone_5.html) :
Note: I test drove the Fairphone 5 with UbuntuTouch for around 17 days two times. Don't worry I hand a second, fully configured phone on hand just in case (And a Android Phone was ready to swap in). I relyed on some Android apps to work but the main once are covered and waydroid helps with the rest.

NOT TESTED YET | 
ISSUES | 
NOT WORKING
✅ Install
✅ Setup
✅ Working with German SIM-CARD
✅ WiFi (With Network enforced Pi-Hole)
✅ Camera (Photo, Video, with and without Flash, Switching between cameras. Sometimes I need to reboot for it to work.)
✅ LTE [Works but sometimes I need to reboot for it to work]
✅ Alarm and Timer
✅ Stability (Fine)
✅ 5G (Somehow works better, faster and more reliable then on Android)
✅ VoLTE
✅ GPS (Works even inside Waydroid. Enable it in UB then start waydroid and enable it there)
✅ Battery Life - Really good! X11 App's running can consume a good bit more.
✅ Heat (More with Waydroid)
✅ Snap's (Using Snapz0r - Many Apps run! BUT onscreen keyboard dose not work in general for snap on UbuntuTouch! Normal USB-Keyboards do!)
✅ Tap to wake
✅ Performance (Good. Display seems to run at 60hz (not the possible 90hz), but performance-intensive stuff like streaming 1080p@60fps is working great regardless.)
✅ SMS
✅ CALL (2G, 3G, LTE, 5G)
✅ FLASH
✅ Vibration
✅ Screen Brightness (Sensitive but works)
✅ Proximity
✅ Rotation
✅ Fingerprint reader (Needs screen to be on. Seems just the way UbuntuTouch works.)
✅ USB-OTG (I had many issues with USB3.X and newer. BUT it was with the phone not matter what. So it is a FP5 or PC chipset issue, not Ubuntu Touch.)
✅ Keyboard
✅ Mouse
✅* Emergency Broadcast (If your country uses the reference implementation correctly it should work if you ask the forum. For me impossible to test. If at some point I get one and I see it for myself working in Germany I will update this: https://forums.ubports.com/post/83531)
✅ USB-HUB
✅ Sleep (Same time everywehere even on LockScreen (Unlike Android))(Same time everywhere even on Lock-screen (Unlike Android) aka. long Screen On times not recommended.)
✅ AUDIO (Is combined on Ubuntu Touch. So don't forget to make your phone quieter in the evening or you alarm will be at full volume or whatever was used last... .)
⭕ USB-MTP (USB to PC. Works but Copy/Past and file management is very buggy and slow. adb shell/pull/push is way better and WAY faster and 100% reliable)
✅ USB-AUDIO (Even USB to AUX Audio. Dose not work for me on Android for some reason)
❌ USB-VIDEO [BUG: Black Screen, Soft/Hard-Reboot and a broken Dekstop on Phone. Tested with USB-C to HDMI (Probably 3.0) and a Dock (Mostlikly 3.X).
✅ Waydroid
How well dose it work:
It works. It is a stopgap and nothing more. I recommend to use it as little as possible and make the battery settings for apps as aggressive as you are able too. I also removed literally anything not needed. Even the calculator.
NOT Working:
Vibration
Notifications inside Ubuntu Touch
✅ NFC (Tested with Flipper Zero)
✅ Bluetooth
✅ Libertine (Tested with Firefox and Signal-Desktop [AUDIO/MIC WORKS IF YOU INSTALL "pavucontrol".]) [Currently, generally broken for Ubuntu Touch. It actually works but one package (libc6) is outdated or miss-configured and needes to be tricked to install https://forums.ubports.com/topic/11112]
✅ Shutdown/Reboot (Was Bugged in the past. Now it works.)
⭕ Snaps - Work relatively well but without OSK it is kinda hard to use. But else stuff like Signal are the best here because of native Notifications System use incl. Screen-Wake, background usage and even calls (Without microphone)!
In the linked blog entry I have made a very extensive list of things that have been tested, workarounds and mods.
I test-drove Ubuntu Touch two times now and I decided it is not for me.
. Meaning this forum topic has received a good amount of attention in the UT space 
. Whenever something about this topic comes up somewhere, I will probably hear about it here first. :grinning_cat_face_with_smiling_eyes:
