Hi dear UBports Community!

I am flicker sensitive, which means I experience significant discomfort from visually imperceivable flickers. This makes modern life very difficult with more and more technology using flicker in different ways.

Some background details:

The typical common cause of discomfort people with my accessibility condition have is the increasing use of PWM based dimming, which currently almost all OLED screens use. And transistor-stack based frame refresh brightness dips which currently to my knowledge all OLED panels have.

Unfortunately there is also a less well know pixel flicker completely software based called "temporal dither".

Its use is generally there to emulate a panel being able to use more color steps than it is natively capable of showing. Pixels switch between colors to show more sub shading of colors.

Unfortunately this also can cause discomfort to someone sensitive to flicker.

Flicker sensitivity is a recognized issue in neurology, particularly in connection with migraine, headaches, and for being able to cause seizures in severe cases.
Flicker-related accessibility issues unfortunately still receive very little visibility.

The issue:

I bought the Fairphone 4 with LCD screen and unfortunately it does use temporal dither on default. In the past I was able to disable that within Ubuntu Touch, but I seem not to be able to reproduce my success.

On Fairphone 4 running Ubuntu Touch, the Qualcomm SDE/DSPP pipeline enables temporal dithering by default. The dithering blocks are visible internally (dither_1, dither_2 in recovery registers), but there is currently no exposed runtime control (sysfs/debugfs/DRM property) I can see to disable them, nor documented panel DT options I can find.

I reset my phone and I cannot find anymore what I did to disable it. Does someone know what I might have done in the past and can point me in the right direction, or know if those options were removed in recent builds?

My knowledge is very incomplete so please have some patience with me.

If a developer active in Ubuntu Touch development reads this: I would be happy to support work that improves accessibility in this area (for example via a bounty or donation).

Hello UT friends,

New to Waydroid and a bit stuck. When I try to run "waydroid init", I get an error stating that "init needs root access".

What I've done so far. From Open Store, installed Waydroid Helper, clicked install. Seemed to go well. I see the Waydroid icon as an installed app. However, when I click Waydroid app, the phone shows what seems to be the startup screen (Ubports ... 5 dots... it blinks through 2 times). I have to key in my phone unlock code. (seems that trying to start Waydroid looks like it reboots or restarts phone?).

However, no Waydroid. From Terminal, when I type "waydroid init" I get an error saying that "init requires root access". I tried the commands from the main Waydroid thread, but still not working.

I've uninstalled from Waydroid helper and tried to reinstall, but same issues, same error. Any thoughts? Any insights or suggestions would be greatly appreciated!

(Running OnePlus Nord N10 5g, Ubuntu Touch 24.04.2.x)

Cheers, Leroy

I generally change the DNS server for the wifi connection using the nmcli command. I have now also tried this for the mobile internet connection. Unfortunately, the result is that I can no longer establish a mobile internet connection at all. Even a supposed reset with nmcli doesn't work. In the settings, an "L" for cellular data is displayed under "SIM 1", but this "L" is missing in the taskbar.

I reinstalled the operating system with the Ubports installer, but unfortunately without success.

Does anyone have any idea how to reset mobile internet settings? Thanks!

Hi there
I am having some issues finding a proper remote desktop tool for Ubuntu Touch (20.4), does anyone have some advice for me? I want to use the phone as a "client" for a network project in school, remoting into it and showing that it still gets a DHCP address, and can access the internet when plugged into a L2 switch.

Hi, I'm having trouble getting my dock to work how i want it. I want to charge my phone through the dock and use peripherals and pass ethernet. I found some sysfs files for power and data roles and tried to set them but they say resource is busy. Basically it either works in power sink/data device OR power source/data host mode. I'd like it to work as power sink/data host mode but have no idea how to do it. Anyone have any pointers? This dock works fine on my other stock android phone. The phone in question is oneplus 5t(dumpling). Running 24.04-1.1.

Hello everyone.

These days Whatsapp seems to have made a major update of its "Whatsapp Web".

This has positive and negative implications:

*Positive: calls are now available in Whatsapp web (you may need to join beta to have it)
*Negative: Whatsweb seems broken, it takes a lot of CPU and crashes, it seems inherent to Chromium 87 we'll see if it gets corrected.

In the meantime I have published an application that allows to use Whatsapp web in a newer web engine through an Electron application. This will hopefully allow to enable calls.

https://open-store.io/app/whatslectron.pparent

Here are the current features:

• Audio calls, but audio quality may vary ( you currently need to enable "Beta" in whatsapp web to have calls )
• Sending and receiving text messages
• Notifications when keeping the app open
• Import / Export attachments via ContentHub
• Sending and Receiving audio messages
• Open URL externally via URLdispatcher

As this is early version there will probably be some small bugs. (Always try to restart or retry in case of a bug ). The application should benefit a lot from upgrade to Mir2.x when it happens.

Do not hesitate to post some feedback.

I received finally a broadcast alert in my UT phone. This is the first time one is shown in my phone, and there have been several in the last weeks.

I'm in Barcelona, Spain, and my phone provider is Orange.

This is a FP 5, and the version I'm using is a daily:

24.04.2x (2026-01-29/3)

In this topic Ubuntu Touch users can receive technical support for UT Translator app, instead of filling the application page with misinformation and bug reports. So, if you experience technical issues while using this app, want something changed or have questions about this app, feel free to ask here.

Questions that have been asked in a way

How do I install languages?
You can open the installer menu by pressing the gear icon on top right corner of the application

Where Bulgarian, Czech, German, Spanish, Estonian, Persian, French, Icelandic, Italian, Dutch, Polish, Portuguese, Russian, Ukrainian?
All these languages are supported by this application and can be installed by choosing "Install basic language models (600 MB)" entry in the installer menu

I have a OnePlus N10 Nord 5G running 24.04. It's working pretty well, but I can't seem to get MMS working. I can't send pictures to my son (gotta share the home made sourdough bread pictures and photos of birds at the feeder!).

This is what Mint Mobile site says to use:
APN Settings

Name – Mint
APN – Wholesale
Proxy – (leave blank)
Port – (leave blank)
Username – (leave blank) 
Password – (leave blank)
Server – (leave blank)
MMSC – http://wholesale.mmsmvno.com/mms/wapenc
Multimedia Message Proxy – (leave blank)
Multimedia Message Port – 8080
MCC – (do not change default values)
MNC – (do not change default values)
Authentication Type – (leave blank)
APN Type – default,supl,mms,ia
APN Protocol – IPv4/IPv6
APN Roaming Protocol – IPv4/IPv6
MVNO type: GID
MVNO value: 756D

I don't see an option in the GUI for a lot of these settings, but I did set Name to Mint, APN to Wholesale, MMSC to http://wholesale.mmsmvno.com/mms/wapenc. I left proxy and proxy port blank.

When I do this, my phone takes forever to start up and I have to force a boot (hitting sound up/sound down/power at the same time and holding for 10 to 20 seconds).

Anyway, sending pictures is not working, and a simple boot fails.

Bom dia. Eu sou do Brazil. Gostaria de saber se é possível instalar o Ubuntu no tablet Samsung A7 lite. Sem precisar de uma máquina virtual. Vocês são os melhores. Sucesso sempre.
