Delayed exposure

I got the advise to try Open camera. To start with it worked very well but now, suddenly, there is a very long delayel from pushing the button until the picture is actually taken. I´ve tried to reinstall the app but it didn´t help. In addition to this the phone crashed yesterday while trying to open Open camera and listening to web radio simultaneously (which of course should be possible). Had to take out the battery to reboot the system(?). Greatful for some advise.
