If you have Sprint's version of the LG Optimus G, you may want to head into Settings > About phone and see if the latest OTA is available on your handset. The update – which bumps the device up to build LS970ZV9 – is just a small one that brings a couple of fairly minor enhancements to the device:
- Visual Voicemail update
- Battery improvements
This just started rolling out today, so don't stress if it's not yet available to you. Give it a few days – Sprint says that all users should have the update "within 10 days."
