I have reason to believe it might be  Spyware...loaded onto cell phone remotely,  By some scumbag who wants to know  every move  being  made by you... while invading your privacy to the hilt! Texts, emails, photos, apps, contacts, location, etc....if this is the case

Carrie -- That's just ridiculous ^

Got a call on my office phone -- they left no message........but have called a few times in the past couple days and somehow I'm not at my desk when the call comes or I would've answered it -- thanks for the previous comments..........this will keep on ringing!

i've been receiving calls from this number also. same thing, he/she hungs up as soon as i answer it.

Always calling my fone everyday it's annoying'
