The new update is pretty big, weighing in at 640.40 MB, and yet LG doesn't provide detailed information on what it contains.According to the screenshot on the left - sent in by one of our readers - the update improves "phone usability and functionality." As vague as that may sound, it certainly looks like this is an update that you should go ahead and download as soon as possible.The update also includes an Android security patch. Unfortunately, it's not the July patch (released by Google last week), but the patch for June. Well, that's still better than having an older patch, right?If you own an unlocked LG G6 in the US and you've received this update, let us know if you're seeing any performance improvements, will you?
