    Welcome to Android Central! Try booting into Safe Mode, which temporarily disables all 3rd party apps. https://support.google.com/nexus/answer/2852139?hl=en

    If the problem disappears in Safe Mode, then something you installed is causing the problem. You may have to uninstall apps one by one until the problem disappears. If the problem persists in Safe Mode, then it's more likely to be a hardware or firmware problem.

    The same thing happened to me yesterday while I was using the Periscope app. Other weirdness happened too. After it finally finished optimizing my apps and finished booting I couldn't get into the Play store for about 10 minutes because it said that I wasn't signed in even though G+ and Gmail and Chrome all knew I was. Also my phone lost all of its WiFi passwords.
