Sensitivity for Game Controls are different on certain devices

Hello,

I am nearly finished with my mobile app and while testing the game on multiple devices (Android) I have come across the following issues:

Nexus 4 phone - everything works as intended, all controls function properly

Nexus 7 tablet - controls are extremely sensitive and make the game unplayable.

The main control is the accelerometer (tilt), but I added a joystick hoping it would be a better option for devices that were too sensitive for the accelerometer use. Unfortunately, it seems neither is a good option for a device like the Nexus 7 tablet.

It would make sense that not all devices are created equal, but does that mean I need to write some type of script to first recognize the device being used and adjust for sensitivity?

Thanks for any help offered!
