the cover is great .... many functions you can perform in the quick-circle, phone, flashlight, calculator, stopwatch, etc. There are several apps that support the circle, very nice and a real hingugger ... was often asked dananch, when GalaxyS5 the window in the cover does not have as many features LG class, and it is square in S5, round design is suitable and very customizable with the clocks on the phone .... I lollipop ... and also goes since everything very good. am really happy. the cover is well made, does not wear out and also does not break out, frequent open and close is good, display is nice protected, and you do not need an extra cover, can also lose weight well, zbum to change battery, is great for wireless load, it works quite well with the LG charger, I invite at night, because it does not matter the load goes slower .... real recommendation, buy .... !!!!
