I've had the amazon app store on my galaxy s3 for a while now and for the last 6 or so months it won't let me download any apps it says the app is downloading but then when the screen pops up and askes me to install it I hit install and it won't do anything. Yes I have unkown apps allowed to download on my phone. Anyone else having this problem? If so what can I do to fix this problem I love the amazon app store
