While unlocking the device with pattern lock type in place, there is no vibration feedback while drawing the trajectory. It's working just fine elsewhere.Please fix this bug!! #samsung
It won't.It's currently reserved for Flagship devices and some higher end A series phones due to compatibility issues or rather say unoptimised for lower end segment devices for now.
There is one workaround for this. Just enable My files labs and turnoff toggle titled " enable default viewer . I haven't tried it but i think it will work.
