iPhone XR only vibrates occasionally
My iPhone XR is turned to vibrate mode but my vibration only works at the moment occasionally or sporadically.
sometimes my notifications will vibrate and then other times it will go hours without them vibrating at all.
its really frustrating as I like my phone to vibrate but my phone seems to be only doing this every so often?
has anyone else had similar troubles and if so did you find a solution?
I've tried turning my iPhone off and on several times but to no avail.
many thanks
iPhone XR, iOS 13
