This Smartphone is a bit similar to the Redmi 4 in specification wise, but there are some modifications done i.e the Extra 1 GB RAM which has now become a 4 GB of total RAM in the device and a 64 GB internal and the processor in it a Qualcomm Snapdragon 625 with 2GHz and octa core processor which is my opinion is huge in terms of multi tasking and Hardcore Gaming.
The display provided in it is a 5.5 in which is great the viewing angle is extremely good , it might a problem for those who dont want there Smartphone to a big in size with hey bigger is better.
The Android version in it is a Marshmellow 6.0 and upgradable toh Nougat 7.0, the storage can be extended to 256 GB which is massive, but I think 64 GB is sufficient enough for all your requirement.
The battery is 4100 Mah which is really good, it can last upto 2-3 days with moderate usage and 1 day with Heavy usage. The front camera is 5 MP and Rear is a 13 MP AF( Auto focus) camera and it has a noise cancellation microphone in it which give decent audio quality while recording video.
This Massive Smartphone cost around 12, 999 INR which a very well specified and budged.
