If I could leave NEGATIVE stars i would. Let a "tech savvy" family member talk me into installing it to video chat with my son. Google product, native to Android, what could go wrong? Now everything works on the handset except for the 'phone! Can't make or receive calls. Can't uninstall it, either, 'cause it's a Google product & native to Android. Maddening. Makes me want to use foul language and smash things. Hope it doesn't cost me hundreds of dollars to replace a much enjoyed handset.
