Why can't my Lumia 640 back out after taking a picture?

Lumia 640 can't back out after taking picture

I'm finding that when I take a picture with the Lumia Camera, I cannot back out to other screens. I can go to the Lock Screen and reopen, but the picture is still there. There are no back arrows or anything that indicate a way to move out. The only way to get out is by restarting. Love the camera, otherwise.

Re: Lumia 640 can't back out after taking picture

Do you see a "processing" message on the screen? If yes then that's normal. The "lag" may be due to the picture not being able to store on the file system and/or the microSD card. Have you enabled the option to save images directly to the SD card?
