I got this this phone a few weeks back. The specs that this phone offers in the price it's available for is just PERFECT. Metal built feels premium n looks good too. It's does have an ir blaster with which u can control ur tv, ac, etc easily. Snapdragon 650( 6 core processor) the latest processor and maybe this is the first phone having it.
Fingerprint scanner unlocks the phone in less than a second. The huge 4050mAh battery will last you for bit more than a day on daily usage. With light gaming. Gaming is amazingly smooth.! And runs heavy games without heating much like the snapdragon 615. 3g ram helps in multitasking.
The Full HD display is beautiful. Super smooth miui and various customization. Can be used with Google launcher or any launcher as well. It supports 4g, 3g as well as 2g. It has a hybrid sim slot so u have to choose if u want a sd card or a second sim card.
The 16mp camera is very good and the beautify in the front camera works very nicely. If u like to take a lot of selfies. And does support 4k recoding but only via third party camera apps eg: Google camera app
