I don't answer calls I don't recognize .Just started receiving these kind of calls & text messages after downloading apps from Google Play. It is from the developers somehow, when you give them permissions on your phone to download their free apps. I am uninstalling ALL GOOGLE PLAY APPS. If you want spam & scam calls & texts to stop you must UNINSTALL ALL GOOGLE APPS , maybe if lots of people do this, the developers will stop selling our info to telemarketers, scammers & spammers.
I don't have an Android or Google Play but this number called me this morning at April 22, 2013. 10:27am. I didn't answer because I didn't recognize the number but my number is on the Do Not Call registry and this number should NOT be calling!
Cheap scumbags call, let it ring twice, and then hang up just when I'm about to push "Accept". Dunno what possible purpose this can serve but to annoy the #$@%! out of the callee???
