Today redmi Note 4 is the best selling phone in India but it has also some limitations. If you are a camera lover then this phone is not for you. It has 13 megapixel rear camera and 8 megapixel front camera. The camera quality is not good either it contain 13 megapixel. As you can see the heating problem in redmi Note 4 which is not negligible. There is also one problem with sim card and MicroSD card either you can insert both SIM cards over 1 Micro SD card and sim card.
