Short answer is no.

I suggest, as a first thing to try, is a soft reset.

[RumoredNow]

Soft Reset is holding the Volume Down + Power buttons until the phone vibrates and reboots (about ten seconds). It will not cause you to lose data, but it will reboot with a cleared out system memory and is a good way to clean up any glitchiness.
