This the best budget phone in India.The sound quality is good But not the best.We can use with ease and somewhat bulky.Design is little bulky by width.I has good camera, Touch screen, user interface is also good.One problem is that the phone heats up very quickly after use of 1 or 1.5 hours. Some times back there was a battery problem bt it was because of the 4G internet which we were using .It has a dual sim and 4G support.thus a very good phone.
