Hey guys I am using the canvas mega 4g(q417). This phone having 3gb DDR3 ram which makes phone faster. In smartphone the most usual problem is the hang the phone due to 3 gb ram I do not saw this phone in hang. The camera is also good and the pictures taken by it 3.5 mb approximately. The speaker of the phone is on the bottom of the phone which makes it more smarter. The battery performance is quit low. The screen is extraordinary. The phone having two sim slots and supporting LTE 4G network but do not support the VOLTE. The phone is also not supporting otg cable. This phone having infrared sensors on the top which used to control tv ac & infrared appliances. The low weight and slim body is also remarkable. I gave this phone3. 5* out of 5
