It seems ever since the os update I can no longer access my clock functions. Everytime I click on the icon it says unfortunately clock has stopped. I've been dealing with it as is but I'd like to be able to turn off my alarm for work when I'm on vacation. It's a Samsung galaxy s4. I've already tried restartin normally and in safe mode with same issue. Do I have to bite the bullet and reset to factory settings? If so how can I save as much as I can on my phone so I don't have to redownload it?
