I purchased mi4i last yr but it contain many bugs whether it software related and hardware related too
And. Many times my phone show black screen automatically , I also called to the customer care they said your parts not avilable in india you have to wait 4-5 months waht was that means you just buy another phone then I drop mail to mi india they also said you have to wait I personally recommend not to buy xiomi mi 4i because phone as well as services provieded by xiomi are very bad
