I have one "generic" Android tablet, and often when I come to install and app, Google Play says it's incompatible with my device. It happens even on popular apps such as Twitter, Instagram, Evernote, Foursquare and even Google Maps!
I know it works, because if I copy the APK from my Motorola phone onto this tablet and install it manually, it runs fine (at least Instagram and Twitter do).
I'm not trying to make Instagram work on my tablet. I'm trying to find a way to install the apps from the Play Store.
How and where does Google Play performs a compatibility check on my device? I suspect said check is failing somehow. I want to be able to install apps that will work on my device and stop Google Play preventing me.
