I think you accidently left the phone on your hood or bumber when you drove away... I found it in the middle of the road and the screen is VERY broken.

However it impressively still rings, I've unfortunately been unsuccessful to answer due to the VERY broken screen.
So if this is starting to ring a bell that it might be you... call or text me, texting is better cause of my work, but if you do call cause you are unable to text because you lost your phone, I understand.
And I guess to ensure I'm hopefully getting the phone back to its rightful owner, please be able to provide the series and/or model of the phone and give an accurate description of the phone's case.
