I’ve had the final release for a day now, installed a few Android apps, but weirdly enough I’m mostly using SFOS native ones (even using the native browser instead of Firefox), so that’s cool.
Thanks for this release 
I’ve put my main sim in it so let’s see how it goes.
So far no issues. Had a few Signal calls, but the recipient told me my voice was cutting every now and then 
Only bummer is the camera, which is due to the device itself (mid-range quality), and the lack of any imaging algorithms in SFOS camera apps or HDR.
Though, I tried Android’s Open Camera, selected Camera2 API in the settings, and activated HDR. And that’s much more better when there is variation in lighting but a bit slow to process the 3 pictures it takes, like a few seconds (still no match of high-end phones).
