Hey,
I recently upgraded from a Samsung Galaxy S21 Ultra that I had for approximately 5 years
To a Pixel 10 Pro XL with GrapheneOS.

And I am looking for open-source alternatives to Samsung OS tools, such as:

A full-screen casting ability, such as 'Smart View', which allows you to display a specific app or the entire phone screen

The Google cast mechanism in GrapheneOS doesn't work for me, (I have sandbox Google play) When I press on it, it never finds anything to connect to,
I have 4 * Nokia Box 8010 (Android TV) and 1 Samsung TV on the LAN

I already tried the following apps

https://github.com/jqssun/android-display-mirror
https://github.com/dkrivoruchko/ScreenStream
https://github.com/JoelPasapera/UltraCast
https://codeberg.org/tom79/CastLab

The only app that came close to what I wanted was
https://github.com/ddagunts/ScreenCast

However, there were delays in both HLS and WebRTC screen casting.

Advanced edge panel gestures, such as "One-Hand Operation+", allow you to open apps by sliding for a longer time or in a certain direction.

I found 2 good alternatives
https://github.com/Imtiaz-Official/Smart-Edge
https://github.com/omeryol/AkisGesture

But I was slightly concerned
Enabling a few substantial permissions to use those app
(I understand that due to the nature of the app, you have to enable a lot of permissions for it)

For example the permissions for Smart-Edge:

1, 2, 3, 4, 5, 6, 7

Virustotal scan of the APK
Is it safe to use those kind of apps? would you recommend using a launcher that has these features instead?

And some kind of automation app like the "Samsung Automation" -

I mostly used simple automation in my Samsung phone, with manual triggers (for battery saving)
It opened several apps, and toggle on certain settings

I found 1 alternative app -
https://github.com/SysAdminDoc/OpenTasker
But have not tried it
Is it any good? does it drain the battery?

Any advice / recommendation would be appreciated
