Jio phone button system is very confusion because many button in hardware hence user disturb use button system and many problem control system of phone. If back to home and back to previous page very difficult not sure button used in back and not sure ok button. And display quality low quality and all of given but WhatsApp not given why? Because WhatsApp very important all personal life now always chatting all people doing WhatsApp. And hotstar video quality low. My suggestion jio phone mobile in button system easily and minimum button all control display and feature.
