I have a car charger for my Nexus Prime (micro USB charger). It's worked fine since I got it in December of 2012. Now it's no longer charging but it's because there is something wrong with the connection with the phone. I know this because when it's charging the indicator on the charger goes red and when it's not, it goes green. Now it's green all the time and if I move the connection a bit on the phone the light will go red but if I lay it down it goes back to green. I had a similar problem with my old phone (a Blackberry with its own car charger). Is this a known problem or I am just unlucky? By the way, I haven not dropped the charger, the home charger works well as does another USB cable that I use to charge my phone from the laptop. Thanks!
