Hi there, I got some annoying problem with Signal, I believe it is Android related wish someone can shred some light

I am using a CAT S52 phone on Android 10, that's the last version it supported, and I set auto update so that I will get the latest apps always, there are few problem with it as follow.

1. I always get greenish selfie when shoot within the Signal app, and I can't shoot horizontally, those photos are nowhere to be found after shoot, so that I can only attach photos I shoot with the camera app directly.

2.There seems no way to change the default camera app on Signal, it does not follow system default but hard linked to the stock camera app

3. Stickers on phone does not show up on the linux desktop app, there seems no way to upload stickers from phone to desktop.

4. Old and deleted chats on phone always show up on the desktop app, there is no option to delete them, I can only clear those chats on the desktop app manually.

Thanks for looking and comment !
