From time to time and when application starts running slowly and crashing, it is good to reset the device.  There are three types of reset:

  • Warm boot /reset  - similar to doing a shutdown > restart in your computer (or the infamous CTRL ALT DELETE in DOS and some Linux platform
  • Cold boot / reset – a cold boot is similar to powering on your computer from a complete shutoff.
  • Hard /Factory reset  - re-image the device to its primal state
