Got them replaced both for free in an Apple store, I thought only one was bugging out but their test machine said both were "broke". It was out of warranty since well over a year.
Not the same but for a more pro approach and allowing to stream to a RTSP Server I use LARIX Broadcaster, which is both available on android and iOS and it's just superb to turn an old phone into a camera, ofc you'd need an other software to actually detect movement and such from the RTSP feed. Scrypted can do that (for example)
Wish I could use LibreWolf as a replacement as Firefox, but for now I have one main issue left, some websites don't work correctly.
For example, on this site : https://appdb.to/ if you click on any app, it'll always open the same app (I think the 'first' one) instead of the one clicked, you can try on Firefox and it'll work correctly.
I actually don't know what cause this issue right now.
Thanks to someone here, I found why some links open in a new tab instead of a popup. Just need to set browser.link.open_newwindow.restriction to 2 (like in firefox), instead of 0.
