I have divided my review into pros and cons, so that it becomes easy for you to decide if you want to but it or not .here are my some of the good things and some bad things about the phone,
PROS
Display - the display on this phone is great although it is only five inch 720p .the brightness and the contrasts are simply awesome .
Battery - this device has removable 2750mAh battery .with moderate usage it can last you a full working day with 15-20 percent juice left, not bad at all .
Sound - the phone features two back firing dolby atmos stereo speakers, and the bass and clarity of the speakers are better than some of the flagship phones which costs more than 20k.if you are a music lover go for it .
Build -it is not a full metal unibody design but it dose features a metal back with top and bottom made out of plastic for the antennas and cell reception is amazing .no call drops.
Hardware It runs on android 5.1.1 lollypop .You get a full android experience as it comes with stock google launcher with no useless bloatwares. Powered by octacore qualcomm 415 chipset clocked at 1.4Ghz .
Ram - 2 Gb ram is available
Internal storage 16Gb.can be expanded to 32Gb via a microSd card .
It supports dual micro sim dual 4G standby 4GLte
CONS
Camera Though Lenovo claims the camera is 13mp but in reality camera is not even 2 or 5Mp, photos come out just horrible,
Front facing camera is 5mp which works like a vga camera so Don’t but this phone if camera is your top priority.
It does not connects with my Logitech x50 external wireless speakers .
Here are few of the better alternatives to this phone
Xiaomi redmi 2,
redmi 2 prime .
coolpad note 3 lite,
coolpad mega 2.5d
Note- there is also a newer version of lenovo vibe k5 , and the only difference is the processor it features a qualcomm 616 chip .
