About Signal UT

[IMPORTANT: Please Read "tips and tricks" section and Do NOT install on Focal (20.04) ]

This application aims at providing a click package of Signal-Desktop tailored for Ubuntu Touch 24.04, with an Interface adapted to the phone screen. This is achieved by applying a minimal set of patches to the Signal-Desktop code itself, and by executing Signal-Desktop in an environment that allows the best integration possible into the Ubuntu Touch system.

⚠This is an alpha build and it currently has some limitations that you can sometimes cope with, with some Tips and Tricks.

------------------------------
-> Tips and tricks:
------------------------------

| - Signal-Destkop can only be used as a secondary client, but you can have your primary client inside Waydroid (with official Signal app or Molly Foss ) on the same phone. Then to link the account do the following with the help of another camera-enabled device ( computer, other smartphone, reflex camera,...) : Open at the same time Signal UT and Signal/Molly on Waydroid on the main device, then take a picture of the Qr-Code of Signal UT with the other device, then switch immediately to Signal or Molly on Waydroid where you have your main account, and scan the picture of the Qr-code on the screen of the other device. Try to do it quite fast as the Qr-Code validity expires after a time that can be quite short. You only need to do this once.

| - During the initial configuration phase the app may not be as stable as it will in day-to-day usage. If something does not work while allowing the microphone or during the following restart of the app (crash, freeze, unable to allow mic), please restart the app and/or reboot the phone and try again. When doing the first account association by scanning the Qr-Code, if you decide to transfer all the messages, the safest is to give it some time ( 10 minutes for example) to sync messages, then to restart the app. The interface may not react properly while the app is syncing messages. After this initial phase the app should be stable and reliable.

| - You can hide the top menus in the app settings, to get a more integrated design as in the screenshot.

| - You will only be able to pin the app icon to the system left menu, while you're on the microphone permission page, or while exporting a file to contentHub and selecting the app.

| - To edit the settings in the left menu, switch to landscape mode and then resize the middle panel to its minimal size

| - Import and export files through contentHub is currently done in a hacky way. It might occasionally fail (including application crash, or application loosing focus) in that case restart the app, and try again.

| - When typing a message you, can expend the textedit area with the little arrow on top of it. It allows to make appear a send button in case you need it.

---------------------------------
-> Known Limitations:
----------------------------------
| - The notifications don't work yet.

| - It is not possible to copy and paste text from other applications

| - The left menu is not yet responsive, and other advanced feature may not display well or work altogether.

| - The application might not be as fluid and reactive as it could be, until we can switch to Wayland.

Very cool that you creat it! Signal is my messanger I liked and used at most. More and more Waydroid get's obsolet.
