The circular opening on the front can be used for the Quick-Circle functions. From LG Some apps are already installed, so that you can see for example, missed calls and answered, call time, reset the camera or listen to music without having to open the envelope. There are other apps in the Play Store, such as a flashlight. Unfortunately, you can only 6 apps at the same place for the quick start in the circle. But it is possible as one of the apps to choose a launcher, through which you can then select additional functions.
Opening the envelope can be folded down completely this. The mobile phone is then for my taste a bit bulky in my hand, but can still hold on tight. You can use the camera in the viewer position also covers, as the opening for the Quick-Circle features free leaves the lens. The speaker, however, obscured, so that notes sound more subdued.
Whether, for a Smartphone Cover good 30 - want to spend Euro, everyone must decide for themselves. I think the price but for the quality it was good.
Overall, the Quick Window Case makes a good and quality impression for the LG G3. For people who are looking for such as a cover for outdoor use, offers the best possible protection for your smartphone, the LG CCF 340G.AGEUTB but due to the opening at the front is limited. If you, like me, more emphasis on it that you do not have to open for every look at the clock or for missed calls the lid, it is perfect and offers a completely adequate protection for my needs. Therefore, I forgive this 5 stars.
