Hello people if you thinking about to buy a mobile phone then I recommended you to buy any model by xiaomi.Because comparison to other brand mi has a bigger battery backup power.Phone Ui very well where other brand run back side. Mi hardware and software uses very well condition. To see mi hardware architecture you will think product price will be high but phone price low comparing hardware structur. I like mi phone very much I used it seen 2 years but no problem occurred yet.
