Well that square camera icon isn't setting off my ocd at all
Lol, I see what you mean.
Took a few pics whilst out for a walk this morning, all auto - non HDR, very little options for the camera so it's essentially just point and shoot. Coming from a note 8, or any other premium phone for that matter and you'll notice how slow the focus and capture is, not sure if this is a hardware limit or software would fix this , but at present it's going to be useless for fast moving objects etc.
Might try a 3rd party camera or the Pixel apk, see if there's an improvement.
Anyway few snaps , Images are okay, bit soft for my liking but decent enough for a daily camera.
