I've got a strange problem on the Arnova 7f G3. I have an old version of the Amazon app store installed which works fine (version 4.0.634.0_463400000) as I can't install the google app store. If I try and install any newer version of the Amazon app store then it doesn't work, none of the icons or buttons within the app store work, I tap them and nothing happens. I've tried reinstalling the app and also doing a factory reset of the tablet, but nothing works. The Android version I have is 4.0.3. I'm not sure what the problem is, maybe a result of having a cheap tablet? It's not a major problem, but one day I probably won't be able to use the current app store version that I have installed, at the moment I get messages every time I open the store asking me to update to a new version. Any ideas folks?
