I wonder if could be related to a faulty charging port or cable? I was having connectivity issues with my OP5t, and it seemed like sometimes it was sometimes charging at a lower rate, despite using the Dash charger adapter or whatever. But then it became hard to charge at all, and eventually I had to replace the port (which thankfully wasn't too hard).
Anyway, just a thought. Maybe try another cable for starters?

Yes, as @stanwood said, very, very unlikely that Pixel 3a will ever have VoLTE with Ubuntu Touch. One of the top Ubports wizards has decided it's not worth it, after not getting the help he needed. The only way it would happen is if another very technically skilled person stepped up.

It's still fairly new that VoLTE works with any devices and has been a huge effort and achievement.
I hope you're able to make the switch - it's a fantastic OS. But the best bet generally is to look over the list of supported devices that do what you need and try to buy one of those. Be careful to make sure VoLTE is supported with Xiaomi. I think it's working on Poco X3 and Redmi Note 9 Pro, but not on regular Redmi Note 9 and some others?
We're all hopeful that this list will expand. A lot of other devices work well, only lacking VoLTE.

Sorry to have been so slow getting to this. Have installed 2025-W21 on my old Oneplus 5, which is not my daily driver. I haven't tested too extensively, and I don't have Waydroid to test it, but:

• calls, SMS, MMS, and cellular data are all working as normal. No VoLTE support of course.

• The Notification LED is not working. While I don't use this phone frequently, it definitely worked in the past. Seems to have stopped working as of this update.

• Emojis show up correctly, and seemingly far more than before! Fewer empty boxes. Very nice!

• The only other thing that I've noticed is that if I click to add an image to an SMS message, select Camera, and take a new photo, after taking the photo, in the screen where you can click to retake photo, accept photo, or cancel, the photo shows up as a solid light grey, with only a column on the far right side of the photo visible. But when sent, it sends as normal. This is a new behaviour as of this update.

Thanks a million to all those who worked on this!

@xixired The normal state of affairs until recently has been that 4G data works, but phone calls wouldn't work over 4G. But on a device without VoLTE (4G phone calls) working, I can still leave my mobile settings with 4G enabled, and it automatically switches to 3G when making/receiving a call.
Interesting that 4G data is lost with VoLTE enabled. It seems that it affects several things. SMS/MMS were also affected as I underatand, and took work to function properly.Note thatI have no technical knowledge or coding skills.

My understanding is that the major system wide work on VoLTE is done, but that it remains for device porters to get it working on their devices. This is easier on some devices than others.

Hi!
Has there ever been talk amongst the devs abvout implementing RCS messaging? I hear it touted as an open standard, but I lack technical knowledge. Would it be as hard to work with as MMS was?
I'm forever grateful to have functional MMS over here in Canada where it's a necessity.

Bravo and thanks for all the recent/upcoming achievements! Really amazing progress!

@xixired Very cool to hear about the 24.04 test build!

Voice over LTE has long been a goal for UT as 2G and 3G cell networks around the world get shut down, but it's now working on dev builds and in 24.04 on some devices, I think including Redmi Note 9?

Anyway, I can't go buy a phone to help test or anything, but felt someone should congratulate you on your progress!
I believe the Telegram channel for porters tends to be more active.

Wow! Sounds like this is very far along indeed! Bravo, and thank you for bringing another device this far!

I don't have one, but hopefully somebody out there does and can try this out.

Looks like you're developing it for 20.04. Are you aware of the upcoming migration to 24.04? And of the newfound progress on VoLTE? My broad impression is that Mediatek devices (which I believe the Redmi Note 8 2021 is) are somewhat easier to get this working on?

In any case, way to go! It's great to have more devices, especially for those of us outside Europe for whom Volla and Fairphone are harder and pricier to get ahold of.

Using Oneplus Nord N10, 20.04 OTA 7:
TL;DR - uNav freezes after location is acquired, Morph freezes upon clicking Allow in Permission Request for location, PureMaps will crash after location acquired the first time, then works well upon re-opening.

-uNav freezes reliably with GPS, seemingly after GPS position is acquired. It will freeze with "Waiting for GPS" still visible, but not immediately, I can still shift from light to dark mode for example, until suddenly I can't click anything in the app.

-Morph freezes reliably after enabling location on navigation websites (tried google maps and waze.) Specifically, I select "Your Location", Morph brings up the UT Permission Request to share location, I click Allow, the website says "Waze/GoogleMaps does not have permission to use your location", I repeat the process, and Morph freezes if I click Allow, with Permission Request still visible.

-in PureMaps' Navigation menu if I use Current Position and wait for the wheel to stop scrolling (position acquired), then click to enter a destination, the app will crash, not freeze. It just closes itself. But then if I re-open the app, I can do the same and it doesn't crash and successfully navigates. I've navigated long distances using PureMaps. I think it may have crashed unexpectedly during navigation once or twice, but generally it works for me. I can't recall it ever freezing.

Not sure why my experience is different, but I've spent some time testing and this all seems to happens consistently for me.

@gn-lin This seems to be the place to start.
https://docs.ubports.com/en/latest/porting/introduction/index.html

@gn-lin Welcome to the community!
It's volunteers who port devices, so unless you can port it yourself, which takes some doing, it won't happen for your device.
The easiest way to try out Ubuntu Touch is often to look for an affordable used device that's on the Devices list. But if you want to try your hand at porting, there's documentation available.

Hi @RuaNYC,
Welcome to the forum!
First, in case the NYC in your name means you're from New York City, please note that at present VoLTE doesn't work on this device using UT. Maybe this will change? But at present, if 3G has been sunset in your area, you can't make calls on this device.

Your writeup was good, I'm not sure why it got flagged as spam.
I've only been through that MSM process once, and it just worked for me, so I may not be of a lot of help.
This said, a good place to start is always to make sure you're using a decent quality / newish USB cable.
@MrT10001 mentions also cleaning the USB ports you're using. And make sure you're actually in EDL mode.
He also said that sometimes he's found that either the global or the EU firmware would work where the other didn't.

The gitlab page for this device lists the 10.5.8 T-Mobile as "Unsupported Device/versions/firmware", but the porter has said that you can install and it will work. What's unclear to me is whether you should use the 10.5.8 firmware or install 10.5.7 firmware on your phone even though it would've normally had 10.5.8.
Maybe someone else is more clear on this.

Good luck!

Old post, I know, but if @thedeafenguy or anybody else has bought from that seller, a report might be useful to many of us outside the EU. I've come across that seller before and wondered.

@qnx_guy I have no specific experience with the F(x)etc, but I've had a surprisingly good experience with the Microsoft Miracast V2. It seems to only be available used though, and is expensive.
Mine has latency that seems to be less than 0.5s, which I find quite useable. And yes, the device becomes a touch pad mouse when connected, though you can also connect a BT keyboard and mouse.
But it does seem like most people have a less successful experience than me.

@carl I will note that android updates for Pixel 3a stopped about 3 years ago. That phone might work for you on UT until end of 2026 if you switched networks. But you should do whatever works for you.

@lduboeuf Shoot, my mistake. I tried today, and Contacts hadn't actually imported. I guess it said "Importing Contacts" when I first connected the new device, but then failed. I very seldom connect to my car, so hadn't noticed.

I'd stayed on Xenial for a long time, and this must have been when they worked successfully. Sorry for the false report.

Yes, well summarized @MrT10001. Though I'll note that not all of North America has lost 3G support. Here in Canada (at least while we remain a sovereign nation) 3G is alive on all carriers for now. Sunset dates range between July 2025 and Dec 2026. My impression is that a bunch of nations in the south of NA still have 2G and/or 3G as well.

If it were me though, I'd either go with one of the pricier but clearly supported devices you listed, or try to hold out a bit longer before buying something, to make sure it works well in 24.04 (and that VoLTE starts working, if you'll need it soon).
My guess is that the coming weeks/months might make it all a bit more clear which devices will have a good future with Noble and VoLTE.

Big thank yous @Moem for showing your work on this and @danfro for getting an up to date Cinny app for us all. Really, really appreciated!

EDIT: Turns out I hadn't tested this in a long time, and my whole report below was incorrect. : - /
Worked in Xenial, not in Focal.

~~My car (Subaru) asked if I wanted to import contacts after initial BT connection, and it all just worked. I was kinda shocked by how simply and successfully it went, both with Oneplus 5T and later a Oneplus Nord N10. I've never had android or iOS, this was definitely all through UT.

All functions listed by @PhAndersson also work, as well as voice commands such as "Call Yumi" or whatever. Clearly the voice recognition is a feature of the car's OS.
It also offers to (import/sync, I can't recal) SMS, which I haven't yet tried, but would test if that were useful to anyone.

I have no experience with either of the BT File Transfer apps, but based on timing, they probably were never updated to 20.04 (probably because they weren't working?)

Maybe worth a try going through any menus on your car just in case there's a way to import the way that mine did? But maybe I just got lucky with a car that happens to play well with UT.~~

@carl Although if you're indeed in Canada, 3G is still supported for now. Rogers has said end of 3G is July 31 2025, Telus Dec 31 2025. Bell seemingly will keep it for longer, some say til Dec 31 2026, except in Manitoba.

The Q&A was very, very encouraging on VoLTE overall, but as stated, it's unknown which devices will get it, and it didn't sound like good news for Pixel 3a.

I don't know if Alfred has moved on to other things, but he was really looking for help from people in the USA to test the Pixel 3a, and wasn't getting it. Maybe since it's supported for VoLTE on those networks, you could see about helping him?

@ywilien Thanks for the helpful info. Who knows, maybe a thread like this spurs somebody to create something like that. It does sound like a pain in the neck the way that @readyblue has to do it. Hopefully something easier materializes.
