Have this phone as a private phone bought since I promised the equipment and the value for money. Professionally, I use a Samsung Galaxy S3. Processing, display, speed and functionality are super. The display is an ideal size. The camera is very good. The battery must be charged at night with heavy use as with any other smartphone. What I like about the removable battery and the option of memory expansion. A memory card is included. It is my Samsung S3 barely after but is reliable. My Samsung S3 crashes every morning and every evening from regularly. Update've made on 4.0. From the price-performance ratio of this cell phone is hard to beat. I would buy it again at any time.
