I purchased this mobile for my wife as a gift in June-2015. Due to its large screen and slim size I went for it. It runs on Android 5.0 and is powered by a 3000mAh non removable battery. It runs on 1.3GHz quad-core MediaTek MT6582M processor and it comes with 1GB of RAM. The phone packs 8GB of internal storage that can be expanded up to 32GB via a microSD card. As far as camera is concerned the back camera is of 8MP and front camera has 2MP. But recently it had problem of Not switching on. The same problem I faced in my Micromax tab also. So request not go with Micromax phones. Its a chinease brand assembled in india.
