I just got this phone and i find the vibrate from hitting a key VERY loud. In my old phone (Samsung Note 4), to change the vibrate intensity, the process was: Settings> Sound> Vibrate Intensity; Then choose from 0-10.
On the Huawei Y6 2, there seems to be nothing of the sort.
(Note: I understand i can just disable the vibration feature, but I've become used to feeling a vibration when hitting certain keys and i like that vibration to be a bit more elegant than it is now (Its actually kind of irritating))
