Phone randomly rings

It's a problem that started a few hours ago, my phone will randomly light up and play my ringtone, but it's not an actual incoming call. For a while it also booted the Car Mode at the same time, but I seem to have disabled that for now. When it's in vibrating mode the screen only lights up, but no vibrating. I can't find anyone with a similar problem. I suppose it should be noted that I did not install any new apps or meddle with any settings.

Appreciate any help I can get.
