After latest iOS Update, home and lock buttons playing up?

This is happening to both me and my girlfriend.

When the device is locked, it'll reboot itself because when I go to unlock the device it says I need to enter passcode because touch ID is disabled after reboot.

Not only that but my lock and home button have become unresponsive at times and require more than one or two clicks before they actually perform any action.

Is anybody else experiencing problems like this after the latest update? My phone isn't old (around 4-5 months old) and my girlfriends is just a year old.
