We just covered a guide on how you can update your Nexus 5 to a preview version of Android L. We also mentioned that due to the preview nature of the ROM, some major bugs and other issues are to be expected. These issues can become annoying when you just want to get something done on your phone. It is expected that many of you may be wishing to get your phone back to where it was prior to flashing the Android L ROM.
