Welcome to Android Central! Are you rooted or unrooted? Stock or custom ROM? Any recent drops, trauma, moisture exposure? Does a reboot help? Ultimately, you may have to try a factory reset--but it might be a hardware failure, in which case you should contact Google if you bought it from Google Play: http://forums.androidcentral.com/go...placement-program-damaged-nexus-5-phones.html
