I bought a Verizon 7" Android tablet that seemed like it would be OK with TouchDRO. It was cheap on eBay, worked fine (I just use it with WiFi, no cell) and had Bluetooth, but on the Google Play store, it says that the app is not compatible with my device. Has anyone else had this issue? Is there a way around it, or did I just throw out $15 on eBay?
