@AppLee
I'll try to make myself available to be there on Saturday.

@Ruesaga
I find that these phones work really well with UT. My preferred ROM for the 9 Pro is the joyeuse_global_images_V12.0.1.0.QJZMIXM_20201107.0000.00_10.0_global_eb964f842a
But recommended is 12.0.3

@Ruesaga
I have two Xiaomi Redmi Note 9 Pro.
One for tests (and back up) and one for my daily use. (20.04 several OTA, and actually one on 24.04-1.x Stable and the other under 24.04-2.x)
I have flashed with ubport installer more than 30 times each one.
Starting from the right Android Stock ROM, I never had any problem with any parts of those phones. All is working well.
As UT is talking with Halium (10 in my case) and Halium is talking to previous Android parts left in place during install, the previous Android MUST be the right one. Not near, not another.
Now, I can only refer to my experience...
My FAI device, the mobile network from Orange.

@lolo
If it's global
https://xiaomirom.com/en/download/redmi-10x-4g-note-9-merlin-stable-V12.5.4.0.RJOMIXM/
Choose the Fastboot ROM
But there are specific ROM for models for India, Indonesia, Russia, Turkey, EEA, Global, China.

@lolo
What is the Model of your phone printed at the back?

@mrt10001
Any idea?

@projectmoon
Currently, with my Linux PC, I mainly use it as hardware key for KeePassXC.
I know it has NFC capabilities (YubiKey 5 series), so it could be used in the same context or to unlock the session or memory encryption.
I'm just curious to know if other users of this device use it in any way under UT.

Hello.
Has anyone been able to use a YubiKey on Ubuntu Touch?
How could this be done?

Really good!
Thanks again.

@projectmoon

RTFM...
I wasn't aware of this folder.
Actually, that would be a good idea!

@bgriffis
If your RPI has ssh and shared ssh keys
You could create a cron job that would synchronise the file regularly with a script like this

#!/bin/bash

SERVER="192.168.1.18"
USER="vlad"
REMOTE_FILE="/home/vlad/Documents/KeePass/keepassdb.kdbx"
LOCAL_DEST="/home/phablet/Documents/KeePass/"

echo "rsync in progress..."
rsync -avz -e ssh "$USER@$SERVER:$REMOTE_FILE" "$LOCAL_DEST"

@projectmoon
And it's an extraordinary piece of work and a valuable tool in my everyday life!
Thank you for that!

Hello.
Normally, installing UT requires Android to be installed first.
Do you think this is possible given the state of the phone?

@projectmoon
Hello.
Oh, good news.
Do you have any documentation explaining how it works in detail?
I thought the BT connection could be established directly.
I'll also look into it on my end.
Oh, okay, you need a LoRa device to propagate the signal.
And the BT connection is used to connect to it...
I'm new to these technologies, but it's clearer now.
Do you have any hardware recommendations for these devices to get started (or a link to them)?

@projectmoon
The application launches and works fine, but the Bluetooth connection fails.
The phones exchange verification codes, then Bluetooth switches to speaker mode and stops.

Hello.
Interesting project.
I have install it on my both Xiaomi Redmi Note 9 Pro running 24.04-2.x.
Would you prefer we discuss the tests here or on the repository?

@Moem
The settings are on the right-hand side (the cogwheel).
The paper airplane is a shortcut to WhatsApp and Telegram Messenger.
Perhaps this feature could be hidden in the settings...

@GooglyBear
I have two Xiaomi Redmi Note 9 Pro phones and I transfer files from one to the other.
For the SD card, I used the external storage app in the panel.
ext4 is usable but cannot be formatted via this app.
Without sudo,,you won't access to the waydroid folder (if you use it).

@bunt7
If you want to know whether the installation matters for UT, then the answer is yes.

Each port relies on Halium, which communicates with the low-level "drivers" that the UT installation leaves in place. The interfaces are adapted for a given version of Halium.
So if you install with the wrong version of Android to begin with, it may not install at all, it may install but parts of UT may not be able to talk to the hardware, or it may work completely (but then that's just luck).

@Sentinel
Have you tried disabling location services in UT before using GPS in Waydroid?
Have you tried the GPS test app via Atpoide?
