I chose the Lumia 1020 as a handy standby camera when I haven't got my normal photography kit with me; However since updating to 8.1 (Cyan), and later to 8.1. update 1 (Denim), I've noticed that the camera appears to work up until the point I take a photo, at which point the taken photo remains on the screen, with "saving" and a progress indicator at the top of the screen.
A reboot of the phone sorts this, but I lose the ability for more spontaneous photos, nearly missing a nice sunset a few weeks back. After reboot, the phone is happy to take photos for "a while", but the fault will return.
I can see how this could be down to going into an app that is fiddling with the camera when it doesn't need to, and leaving it mushed, or a fault within the Lumia Camera app; but has anyone else seen this problem, and been able to figure out the cause, or even a faster way of getting the phone back into a position for taking photos?
