dear dont compare Samsung to mi.speed depends on "no of active connections on single tower" for eg if you have wifi connection and you getting speed is 100 mbps on single mobile or laptop .if your family or friends join your wifi your speed will be divided between all wifi users. so check at same time by clearing your phones memory first as some apps are downloading data in the background
you may bhi somewhat right but there is issue in calling network if use this m30s phone at roaming it shows some area sim1 not allowed or in sim status shows more then -90dbm signal strength of both idea and jio sim
No its good. Although it have network infication issue. Mi alyasy show more strong network that is falSe then Samsung. try Download same contents in both handsets with same browser then you will find samsung is much better
