Problem while playing Temple Run 2 on Nexus 7 and Nexus 4

Many people are addicted to playing Temple Run 2 on their Nexus devices. But many times when you want to consume your energy by double tapping on your screen instead of getting the energy the screen size doubles.

Well there is nothing wrong with the game or your device or the OS either. Its one of the modes in the Android which double taps zoom your screen.

Simply go the Settings > Accessibility

Magnification Gesture > Off
