Hello, I changed my Samsung Galaxy S3 for this smartphone. Product quality, battery with great autonomy. A very good quality screen, real 5-inch format from the much finer edge than on my old S3. Ditto for the sound, audio quality on this smartphone. For the photo, a very good camera with flash and any similar functions has my old Galaxy S3 with more significant, 4G! the materials that make up this smartphone are noble, brushed aluminum non-slip plastic for the hull. The software allows a use and a simple and functional grip of this smartphone. only downside, it lacks some functions that I had on my Galaxy S3, so it is not obvious to use the controls on the back of this smartphone to turn off the smartphone and raise or lower the volume, but it is only a matter of habit, now the grip is incredibly easy. I admit that I was rather reluctant to buy an LG smartphone, I took the time to make my purchase, but I am delighted with my choice. I recommend this smartphone that have nothing to envy the competition. Great product!
