Xiaomi hit the market by a huge amount of specs with low price tag in comparison with other phones
And the performance is okay
Eventhough it laks the dual sim operation
Because when using dual sim rathe than one sim and sd card the phone takes more time to detect, sometimes shows no service.
Another problem with the heating issies while playing high graphics games and mkv videos this dude heats up very high.
So it needs more development and corrections
