How to trace your Samsung phone.
My phone was stolen on my birthday at my friend's bday party. Everything happened so fast that I left the party after a few announcements regarding my phone. I got home, explained to my hubby what happened, & committed to getting my phone back.
I am currently typing from my previously stolen phone. I am so grateful for Google technology and Samsung for great security features that can not be easily bypassed.
