Random Reboots -- Possible Solution

The solution to my random reboot problem was SwiftKey. Here are the steps I went through to find the culprit of my reboots.

1. Performed a factory reset.
2. Started loading basic application (all Google apps) on the device. I did not add any other application for a few days. No random reboots.
3. Added third party essentials one of which was SwiftKey.
4. Had a random reboot overnight. And then subsequent reboots throughout the day (at least 3).
5. Removed a few of the essential apps including SwiftKey.
6. Installed apps one by one and when I reinstalled SwitftKey, reboots started again.
7. Have had SwiftKey uninstalled for a few days now and not a single reboot since.

Just my experience. Thought I'd share it with others having issues with random reboots.
