What the hell is this, mi band is not compatible with mi (redmi note 4) mobile wow it's showing pop up that upgrade your miui version for getting call notification. If company is not giving any update for this mobile that is not my fault. But before last update it was working fine then why the hell are you developer are doing if it's not compatible with your own company mobile. Please fix this asap i have only one mobile that is little bit old but it doesn't mean you guys will do this to us.
