Miatoll devices UT Focal support

Damian1944 · 21 Sept 2023, 19:01

@beyolf Good evening, thank you very much for your work on updating this group of phones to UT 20.04. I'm using Redmi Note 9 Pro and I've been wondering for the last few months if there is any solution to make Miatoll devices live again. I started using Redmi with UT as my first phone a few months ago. And now I'm happy that the process is back on track. Thanks a lot and I will be happy to test the new version of the system

Hey thank you very much! I am glad that i managed to bring it up with the help of the community. If you need assistance with anything you can join the Telegram group and get in touch with us.

there is a know issue with freezes between app switching and there is a temporary solution for that issue I am currently working on more longterm solution.

Good luck and hope you enjoy it.

Update: Guys the freezing problem was fixed today. I made a MR with the fix and soon it will be available for all of you.

have a good day/night.

Update: all of the MR fix requests were accepted, probably with the next OTA update the flashlight fix and the freezes fix will come on your devices.

Please contact me if you find any issues.

Thank you for your support.

I don't own this device but thank you for the work

One question though, you said that app switching issue is not this port specific, does it means that it can occur on other devices ?
What was the issue origin ?

beyolf · 22 Sept 2023, 12:16

@Keneda

It turned out to be kind of port specific, but yes it can occur on other devices with a bit older kernel as miatoll was. The fix is quite easy.

The Xperia port had the same issue as miatoll and it turned out to be the same kernel problem even that both devices use different kernel versions.

https://gitlab.com/ubports/porting/community-ports/android10/xiaomi-redmi-note-9-pro/kernel-xiaomi-sm6250/-/commit/c45ed3b1cdf7d8e485bb4b50dfd1ec9842b4bd64

This is the source of the issue. If in the kernel the

oom_adj
oom_score_adj

Files are with read only permissions 400 the problem will most probably occur. Because lomiri-app-launch spawns SUID helper when it cannot set the scores in this files by it self and the spawn is done by forking so the freezes occured because of the forking.

The problem with lomiri-app-launch is that it spawns a process for each thread to adjust the score which is not very good and in some applications as chrome this is a lot of processes and forks which copy pages and that's slow, but by making lomiri-app-launch able to set the scores by it self then it does not need to spawn SUID helper so no forks no freezes.

Hope I managed to explain it clearly enought.

If you need more information you can contact me in telegram.

Small update: The automatic screen brightness is now fixed and working properly. i made an MR with the fix so it will be available probably in couple of days

Have a great day/night

@beyolf Hello! I will join the Telegram group with pleasure. Is Telegram the most convenient way for you to report potential problems? I've now successfully installed Focal devel and it is running without any problems. Once again many thanks and congratulations for maintaining the miatoll port within 6 days. As I wrote above, everything works very well - there is a visible graphical improvement and the OS runs much faster. In the agenda of things that could be worth considering, from my small experience with UT, are: time indicator on the bottom bar partially hidden by the round corner of the screen and the similar problem on the left side in horizontal view (but it is not a important bug, only esthetical); losing mobile coverage sometimes but without any notification (it is important, but I experienced this problem on Xenial, maybe it is solved on Focal); no MMS messages (medium important, on Xenial too, it had worked well in the beginning and ended later). And finally, I would like to point out that as a user of Ubuntu desktop for 10 years, I was happy to install UT. But I didn't think it would be easy to use the UT phone everyday / as a first phone. But it is possible. I use Redmi Note 9 Pro with Ubuntu Touch as my main phone since 3 months - and it works great.

Hello , I am very happy that you managed to install focal without problems. Hope you enjoy it.

You can report bugs here, in the gitlab or in the telegram group. I personally am most active in telegram , so it's the easiest way to reach me.

Hope you have pleasing experience with UT on miatoll. I am doing my best to improve the port as much as I can.

@beyolf Good evening. Everything is still going great at Focal. I just want to mention three points:

A big advantage - after upgrading to Focal, I had not noticed any problem with losing mobile coverage without notification. This was sometimes a bug with Xenial, as I wrote earlier.
The camera does not work after starting the app. It works if I kill the process and restart the app. This is a consistent issue.
Not important, but you might want to know - with the Polish language in the system, there are a few places where I have English notices: keybord & time and date on the top bar, as well as the notification on the main screen before unlocking.
And another advantage - the system reads the memory correctly. Xenial has doubled it.
I am using the latest r25 build. Have a nice Sunday!

@Damian1944

Thank you very much for the notes.

I am currently investigating an issue , but when I finish I will check the camera problem and try to fix it.

@DPITTI
The stock firmwares are listed in a link in the device info page.

You were never "available" for testing , because testing is a personal choice. Nobody is forcing you to use or test UT. Nobody asked you to test anything , that is your own personal choice. I only updated you when there is something new as you asked me to do. The problems which you face with the UT groups is consequence of your own actions and behavior and i am not responsible for that.

Have a good day.
