Bluetooth gamepad problems

[Android Central Question]

Hi guys. I have a strange problem with my new galaxy a70. When I pair my Sony ds4 controller to it, it just doesn't work, in Android or any games. The controller works on my old phone. I've tried changing to avrcp 1.3. Also tried pairing it in safe mode,reset network settings, factory reset. Nothing helped. Another problem with it is when I try to disconnect the controller it takes ages and it makes my wifi stop working too.
