I am using this device from last one month. it surprised me because it does not have the basic sensors. it doesnot have the autobrightness sensor that means you have to adjust the brightness time to time which is quite disguisting. it doesn’t have the amoled display just the simple tft display. speaker is not on the front but on the side which is quite akward. it has the memory of 16gb which means you have to buy a memory card along with this device. it lags with multitasking. Moving to the camera, it overexposes the images in the automode. it is very difficult to take microshots with this device as I already said it doesnot have the basic sensors like laser autofocusing system. the fingerprint sensor is not so fast I would say 70% working perfomance of the fingerprint sensor. it doest have good battery backup that means you have to charge your phone everyday. it doesnot have the backlighting button which is quite basic.the gaming performance is quite horrible, it lags severly. the most disgusting part about this device is the lack of basic sensors.
