One of the best selling OEM accessories has to be that Circle Case for the LG G4. The case protects your screen but still gives you important information like time, weather, and notifications through the circle cut out on the front. You don't actually need the Circle Case to see the circle clock widget. If you want to just quickly check the time without waking up your device simply place your finger on the middle of the screen, then swipe down, as long as your finger remains on the screen the clock will be displayed. Once you remove your finger the clock goes away. This appears to be working on most models, but has been reported as being disabled on the AT&T variant.
