I was playing with the camera on my Z2 and noticed that the dedicated camera shutter button wasn't working. I press the button, it focuses, and the button on the side disappear as if it were about to take the picture, but it just stays that way until I release the button. When I release the button, no picture is taken and it unfocuses and the buttons come back.
My phone is bootloader unlocked, rooted, and I removed some things via Titanium Backup. Did I somehow remove a piece of software needed to use the button correctly?
Any help is appreciated.
