When adjusting certain settings in the options menu, such as the Button Size slider and the Sensitivity slider, they sometimes set back to zero when pressing the back button.

This doesn't always happen, but can sometimes happen a few times in a row making it hard to change settings.

Steps to Reproduce:

• Open the options menu
• Select the controller options
• Adjust the Button Size slider
• Press Back button (top left)
• The slider will be reset to zero (minimum)

I'll upload a short video clip of the bug. If you are trying to reproduce this, you might need to try a few times.

(edit: In the video, when the slider is going back to zero, that's me trying to hit Back)

Still an issue with the sliders in 0.16.0 beta 1 - Android LG Nexus 5
