On spec it met sound like this phone great but it is not because miui.I have purchased this device on 20th dec from mi.com.It took 9 days for deliver more than that estimated given to me by mi india.
Miui rom is ram hungry rom, 2gb of ram but still less than 850 ram available on first boot and whenever I reopen app I get reload.For Example I was browsing on chorme then I get whatsapp message after I reply to that message and open chorme from recent tab the webpage gets refreshed.I was on 3g and that cause me lot of data.
This heats a little and doesnt become very hot.Camera, speaker, display, build are good but the software lets the phone down.
My suggest buy other phone than this device like lenovo a7000 plus, yuphori, meziu m2.These device come under the Rs 7500.
