I am using this device. It has 1gb ram and doesn't work like that. The vibration of the phone has damaged in the 2nd year only resulting in opening the device.
I am not even able to use apps like whatsapp as it hangs as if the ram was 256mb. Internal space is 8gb out of which available space is around 2gb which is automatically occupied by cashe and other app data so memory card should be higher than 8gb.
