Wait until dark, shine a flashlight around and look for reflection off the glass. Or use a metal detector...

Note to self: put a piece of retroreflective tape on my phone.

(I already have a roll of DOT stuff for bicycles, required on the front and rear forks if riding at night)

I did that with my dji drone, figured that when I eventually crash it and it ends up in some dense foliage, I could just go back at night and look for it with my torch looking for shiny 3M reflective tape.

It was dark already. We did a lot of grass-searching with flashlights - but the phone was on top of the ATV, in a tough-to-spot location (by the handlebar or something, between some cables).
