I am buy xiaomi mi 4s it has 8 gb internal memory and it has very less battery backup it hang ragularly.when the call coming it is become very heat.when ever other company phone never hang.it has very high rate.in market it value is 15000 when ever other phone is available at only 6000 having same feature.it is not available in market it is only available at online shopping. Xiaomi camara is very worst quality. the front camera us 2mp.it does not support many application like fifa 16.it is available in only two to three colour.it design is very worst.so my advice to you that not buy this phone.
