Have you considered that doing something different is not ignoring anything.
As for intuitive this is relative to what people have used before.
People will have there own personal and group goals for these FOSS projects. Just because they don't align with your vision of what you believe should be done, doesn't give you the right to complain other people are wrong. It contributes nothing to moving forward.

To progress further with the initial flashlight idea, controlling the flash directly appears to work fine in the following way.

#!/usr/bin/env bash

flashOff() {
	printf '%s' "0" > /sys/class/leds/led:torch_0/brightness
	printf '%s' "0" > /sys/class/leds/led:switch_0/brightness
}

flashOn() { # 2 appears to be the minimum brightness value possible
	printf '%s' "2" > /sys/class/leds/led:torch_0/brightness
	printf '%s' "1" > /sys/class/leds/led:switch_0/brightness
}

So with a loop I can have a nice flashing pattern at the minimum brightness.
Just need to find what to hook into so I can have it only running only while there is a green notifications icon.

As for using the screen, I think the green envelope icon, possibly slowly moving along the top edge of the screen (to minimise any burn in); would be a nice option there.

Just a quick post for forum lurkers that updating to 24.04-1.0 stable on Fairphone 5 has gone smoothly for me.
To install use the ubports-installer select stable and leave the wipe data unchecked.
Then do reinstall all apps from the system settings menu.

Issue with Libertine is resolved only thing I have seen an issue with is OSM server not starting for Pure Maps but I haven't tried debugging yet.

@knuddel823 It's recommended to install Fairphone version of Android 13 as per the install instructions.
https://devices.ubuntu-touch.io/device/fp5/release/noble/#installerDownload

All notifications are affected.
The current options are wait for it to be fixed in stable or switch to daily.

Run the installer, it should detect your device and then use the option to reinstall but don't tick the wipe personal data option.

Comparing with flashlight on and off.

Off
/sys/class/led/led:switch_0/brightness = 0
/sys/class/led/led:torch_0/brightness = 0
/sys/class/led/led:torch_3/brightness = 0

On
/sys/class/led/led:switch_0/brightness = 1
/sys/class/led/led:torch_0/brightness = 127
/sys/class/led/led:torch_3/brightness = 127

I'll need to test if changing these will trigger the light, certainly just making switch_0 = 1 doesn't work.
Not sure if this is the correct way to interface with these.

As for monitoring for new messages I'm wondering if dbus-monitor could be used...

@t12392n
I can confirm this too.

@gpatel-fr Apologies if I wasn't clear.
It seems I recall incorrectly, have now found the correct information
You must not relock the bootloader if you downgrade Android version due to anti rollback protection.

I have the occasional issue of the keypad switching between number pad and keypad really fast on boot. I have read that is also related to the fingerprint reader.
I also as I say have the fingerprint working fine for the fingers I used when installing UT initially.
The device was BNOOTB and I flashed A13 from the FP website before installing 20.04 daily which was the only option at the time for FP5.
It would be pretty inconvenient to full wipe at this point without some backup tool as it's my daily drive. I would have to be certain it resolves the issue as it's not that inconvenient my fingers I use generally work even if I can't add new ones and I get the OP's error in the fingerprint menu.

Is it not also true you shouldn't downgrade a A14 to A13 as the bootloader will lock?

This is marked as a known issue and I have seen other posts about it.
I also still experience issues. I can't add new fingers at all but mostly my fingers I did from the installation time work most of the time.

Is there any confirmed solution that can be shared with people that are not on Telegram?

Ah thank you. This seems to have been set to tethering.
I wasn't aware this would also stop file transfers when I've been looking to diagnose why.
Resolved

My FP5 no longer appears in the devices list of my Ubuntu Desktop and seems unable to mount since the weekend.
I can't currently transfer files between them via USB which is pretty annoying.
The device was on Daily I have used the Installer to clear and reinstall Stable. Neither work.
The desktop has been rebooted, and the device shows as Qualcomm FP5 in lsusb when connected.
Anyone else experiencing this?

@slowcyclist
There is a bug report which I found later.
This is supposed to be fixed now, however, it is not for me. Just sits with Server Stopped forever.
I don't see how I can disable and restart the service if you can't get past "Server Stopped" to get to the menus. Seems a clean install of the app would likely fix it, but how?
Is there some way to "purge" click packages; as in, remove all the configuration files when you remove them?
I'm thinking it may just be easier to have a list of packages, find out how to backup my contacts, call history and messages then wipe clean? Is there some information on doing that? Maybe an app or something built into UT to do that would be nice.
