The Gallery doesn't seem to be working correctly following the Janaury update, both when accessed directly or via an app such as Insta. Gives a black screen, but the seems to be intermitent.
Have also experienced the camera freezing and giving a message to say cannot use the camera when another app is using, which gave me concerns over what was accessing my camera at that time.
Any thoughts please?
Have you tried force stopping and clearing the cache and data on the stock camera app? Have you tried wiping the cache partition on your device?
