I have spent the last 2 hours in a major panic because I lost my iPhone X. So, I called it from my Land Line. LOL Every damn device from phones to iPads starts ringing because I have T-Mobile Digits set up (awesome stuff, btw). So my whole house is ringing and this does me no good. Then I remembered something about registering my phone with iCloud. I went to the iCloud site there was "Find My Phone'. Cool. It found EVERY device I own, and it said the phone is indeed in my house somewhere. Luckily, instead of just dialing the phone so you can find it, it sets off a Sonar like Beacon on the device you are looking for. I set it off, and I heard it !!! Hot damn, now we're getting somewhere I slowly worked my way to it, and finally found it. It was under the Bed. Apparently I knocked it off the nightstand in my sleep, and it hit the leg which tossed it up under the bed. Whew!!! This is a classy feature.
