Xiaomi redmi 4 is good chinese phone this company of phones all nice last year lounched redmi 3s prime about 8to9month this company became fan of 1to2million customer.so xiomi redmi 4 designed by metal body so attractive 150gm and 8.65mm thicker4100mhbattery.battery backup is nice once u charged u will enjoy approx2days.it is 4g phone but it is major con that is hybrid doul sim means u will use one at time one sim and one memory.
If u use both sim then first sim only work 4g.finger print sensor work good.camera performance is average 13mp f/2.0 front and back 5mp f/2.5.but focusing of camera is fast.and one con in cemera is whenever u on HD mode then its take too much time to take photo.5inch hd display ( 720×1280) and video recording in 720p.it is powered by an octacore qualcomm snapdragon clock at 1.4Ghz.this phone runs on androide6.0.1 marshmallow with MIUI8.2.so its good for gaming just like u can play asphalt8, cut the rope.play smooth.so on an avrg good phone value for money under 10k.
