If the game isn't gameplay related, but mostly hardware specific, e.g. it works on one device but not another, then we will need more information from you.

Android

Be sure to collect the device model number and android version number before you start.

Then you will probably want to collect the logcat output or a full ADB bugreport

To send us the logcat output,

• if you use Android 4.0 or earlier, then use the ADB logcat collector or something like Catlog
• if you use Android 4.1 or later,
• if you have root, then you can still use the above
• if you don't, you will need to install the Android Debug Bridge environment and collect the logcat manually. Here's a tutorial to install ADB.More information here
