There is already a software update from Verizon for new LG Spectrum owners. This one is designed to address a Netflix playback problem on the 720p HD phone. Obviously, this was a pretty big deal, so they decided to nip it in the bud immediately. As soon as any users get the new LG flagship, you should look to get the OTA patch. It will upgrade you to version VS920ZV4 and is a 10MB download.
