It does not have LED notification light. Everytime you have to unlock the phone and check if you have received any notifications. Capacitive buttons are not backlit and thus it feels weird to navigate in dark conditions. I have to predict the buttons in darkness for using the phone. There is no backlit for the buttons. Everytime you are in a low light condition you have to predict the buttons back, home, menu. hope that you touched the right button.
USB OTG is not supported. That means you cannot watch any thing from your friend`s pendrive .you are confined to the phone storage. This phone is worthless in terms of usability.
I spoke to Flipkart customer care, they cannot refund it as the phone is not defective. whatever I have listed is out of its specifications. A 4g device which lacks basic usability features which are present in older phones.
