Verizon is pushing an update to the LG G4 on its network. The details of the update are scarce as Verizon has yet to post the official changelog, but users in the Android Central forums are reporting some noticeable changes. Depending whether or not you were able to grab the update from October, you may notice a large download of over 400MB, or a smaller one that is around 60MB.
Users are reporting that the phone appears to be running smoother, the typing experience has been improved and notifications are working as intended again. If you have not yet received the update, you can check for it manually by heading into your Settings then About Phone.
