Has anyone else had this issue? My phone every now and then randomly vibrates 4 times with no notifications or icons in the top of the screen?
Perhaps try putting the phone in Safe Mode which disables your downloaded apps to see if the issue stops and if it does then one or more of your apps is causing this.
If it continues then it could be some sort of timer / clock / alarm - maybe.
Daily Driver > Samsung Galaxy s²² Ultra 256Gb in Phantom Black.
The advice I offer is my own and does not represent Samsung’s position.
I'm here to help. " This is the way. "
Had a play etc over the last couple of days and it’s something that is connected to using the galaxy watch that I’ve narrowed it down to.
My Samsung s10+ never vibrated uncontrollably until I bought the galaxy active2 watch. I think it's definitely the watch that's caused it, but by switching it on and off again it stopped.
