So, I thought I'd try installing Trials Frontier as my research turned up some possible controller compatibility. I use DropBox to "sideload". I can download the .apk, and enter the install process, but then it will run for a minute and say "Game not installed" or something to that effect. Any thoughts? Any other games that do this? I'm not new to side-loading, but I'm hardly an expert. Any help would be appreciated. Thanks!
