Resolved DualShock4 behaves incorrectly on Android and IOS

The problem is that when you press L1/R1, the PlayerInput component changes the device and scheme to Keyboard:/Keyboard6. https://imgur.com/a/uoVsA2h This undoes past gamepad actions and does not register L1/R2 actions.
Input system version 1.3.0
I tested in demo Unity project - Warriors' Example Project https://github.com/UnityTechnologies/InputSystem_Warriors.git
Is there a solution to this problem?

 

I sent a report
case 1404866

 

ok i found the solution.
the reason why this happens is that on android Unity creates a virtual keyboard and mouse (ps4 touchpad), and one of the keyboards reacts to the buttons R1 R2 L1 L2.
the solution is to simply disable these devices

Code (CSharp):

1. private void FixPS4Android()
2.         {
3.             if (Application.platform == RuntimePlatform.Android)
4.             {
5.                 foreach (var item in InputSystem.devices)
6.                 {
7.                     if (item.name.Contains("Keyboard") && item.displayName == "Wireless Controller")
8.                         InputSystem.DisableDevice(item);
9.                     if (item.displayName == "Wireless Controller Touchpad" && item.name.Contains("Mouse"))
10.                         InputSystem.DisableDevice(item);
11.                 }
12.             }
13.         }
