I AM USING THE MODEL FOR MANY DAYS. SO FAR SO GOOD, THE PHONE IS BIT SLOW AND THE CAMERA IS ALSO NOT SO GOOD. BUT IT SUPPORT EVERY APPLICATION AND ACCORDING TO THE PRICE RANGE THE PRODUCT IS VERY GOOD. THE WIFI CONNECTIVITY IS ALSO VERY GOOD, EXTERNAL MEMORY CAN BE USE UPTO 8GB, THE SOUND QUALITY IS ALSO VERY GOOD, THIS IS MY SECOND SMART PHONE AND I REALLY LIKE THE PHONE. THE LOOK OF THE PHONE IS ALSO VERY GOOD, THE GORILLA GLASS IS ALSO VERY STRONG.
