Xiaomi mi pad even though it is succesful but it failed many aspects like main disadvantage is that its touch is not all good.the buttons while we use in tablet in landscape the buttons are hard as u have to press the buttons hard.it doesnt support some andriod aaps like google keep.times of india.food panda.paytm etc.wifi reception is much slower.apps cannot be moved from phone to sd card.its also get heated up while surfing or playing games and the major defect is it doesnt have gprs.
