Micromax canvas 4 plus a315 is a really lite and a quite slim phone. The design is similar to that of iPhone 6 and is good! The 13 MP back camera is good but could have been better since the phones coming up now have better cameras which are cheaper than this one.
Front camera is also quite appreciable. Front camera works amazing with Youcam Perfect and clicks some amazing selifes! It has an octa-core and 1 gb ram which is cool and everything works fine with this configuration. The display is not appreciable. High quality photos get blurred after a bit of zooming in. The sound is very low which affects the video and audio recording of the phone.Also the phone's battery backup is not good at all! You have to charge it two times a day to keep it going.
Otherwise almost everything is fine.
