I bought redmi 4 on January 2018 at Rs 8300.It does not worth its cost at all. From the first day I am suffering from its hitting issue. It takes time about 2.30hr to be fully charged. But after that the phone becomes too hot to touch. The battery claims to be 4100mAh, but it doesnt run 2days. I cant call anyone more than 15min as it becomes hot. I also heard about its bursting news. So I am really scared to use it now.
The phone is not as fast as compared to other 3gb RAM phones.
But its camera is very good. Picture quality is awesome. Sound quality is quite good. The dual space feature of this phone is special but after activating it phone gets slow.
The phone contains two slots for SIM but if you want to use memory card you have to replace ur card to the 2nd SIM. Its very bad feature for Rs8000 phone.
I suggest you to look for other phone if you dont want hitting issues in your phone.
