Yes, I was in a friend's pool yesterday, so obviously without my phone, and I felt a vibration that felt exactly like Snapchat. I just chalk it up to muscle twitches.

I don't cause I don't use vibration that often

One of the names given on Wikipedia is a "fauxcellarm" which I love.

"Researcher Michelle Drouin found that almost 9 out of 10 undergraduates at her college experienced phantom vibrations" so it's certainly common.

Vibration "ringtones" should be a thing. Less likely to confuse with phantom sensations and other people's phones vibrating.

I thought I was getting these but then realized that my Fingerprint reader was triggering in my pocket and it does a very light vibration on a failed Fingerprint attempt.

Apparently muscle twitches and spasms. Perfectly normal and common. Before phones, we all got them but just ignored them and filtered them out. Phones trained us to monitor for them so we now notice them.

The ridges of the weave in my pants sometimes produces a vibration that is similar frequency and intensity as my phone vibrate. It totally triggers the check the phone reflex even if it happens while my phone is in my hand.

Yes, but additionally I started getting actual random vibrations from my phone with no notifications. After a while I discovered that if I put my phone on a library book, my phone will buzz. I tested it over and over before believing it. Guess it interacts with the electronic tag the library uses for checkouts.

I keep my personal phone in one pocket and my work phone in the other, I frequently feel the vibration in the wrong pocket and end up checking the wrong phone

Yeah. Sometimes I hear the message ding too. Guess I’m lonely.

Not since I turned off sound and vibration in my phone.

Before that, yes.

A long time ago.

These days, I keep both audio and vibration turned off. If somebody needs to reach me they will want to message and then wait until I check.

I started getting those daily a few years ago. It annoyed the crap out of me so I decided to use ringtones instead of vibration. Took a few weeks for the phantoms to get out of my leg.

Assuming I'm understanding what you mean, I did somewhat recently. I don't remember what game it was but it was caused by a game I downloaded from the Google Play Store. The game never gave me notifications as I actually had them disabled, but the game would cause my phone to vibrate randomly for seemingly no reason. As soon as I uninstalled the game, the random vibrations stopped.

30 years ago we called this Beepilepsy. You fail History.
