I am using this phone since 5 months but till now I got no issue like hanging heating. The apps and high ended games runs very smooth. After updating to latest MIUI9 its works great day by day. The camera is not like the other brand phones its only average but performance wise it is great phone. The battery backup is also awesome with heavy usage all day like 4g net and games its gives around 10-11 hours of battery life. One bad thing of this phone is its hybird slot but still it is a great phone.
