How to change hardware button behavior

HellandB

I would like to change the bahvior of the buttons next to the finger print sensor. I know you position will be swapped if you change the navigation bar settings: Settings > Navigation Bar > Choose Navigation Type.

But I would like the "menu" button to be "Recent running tasks", like the software menu is.

I tried using the app Button Remapper (No root), but wasn't able to find out how to change this button. I could only get it to work for the volume buttons etc.

Remapper is good, works fine for me, even with SW buttons. I mean just play with settings it is what u looking for ;)

Thank you for the replies, i tried following the post, but I am not able to change the menu button to be recent running taks. If you where able to do this with Remapper or Switch Access, please provide a step by step. As mentioned earlier I am able to change it for volume button, also able to change Home button behavoior with Nova launcher..,

Hello,

what are the keycodes for the two hardware button. One has 139 - that is Function Key "F9". What is the code for the second one ?

Kind regards

@Klarseher
The Menu button has keykode"Keycode_menu", the shortcut button on the side has keycode "277", I am not able to assign the back button thus not sure what the code is.

I did some more testing found out that Switch Access is working for the menu button if  Navigation bar layout setting (settings >  Smart Assistance (heading) > Navigation Bar) is set to the second top option (Recent running tasks, home, back). But if changed to the top button (back, home, recent running tasks) the Switch Access settings stop work for the menu button.

\n\n@HellandB:

I commented out code 158 and code 139 in three files in keylayout folder.

As a result, both hardware keys beside home button are disabled !!! A first step ..

1. master@HAL-9000 c:\Users\master\AppData\Local\Android\sdk\platform-tools
   
2. > adb shell
   
3. shell@UMI Plus E:/ $ su -
   
4. root@UMI Plus E:/ # cd /system/usr/keylayout
   
5. root@UMI Plus E:/system/usr/keylayout # mount -o remount,rw /system
   
6. root@UMI Plus E:/system/usr/keylayout # vi Generic.kl
   
7. root@UMI Plus E:/system/usr/keylayout # vi mtk-kpd.kl
   
8. root@UMI Plus E:/system/usr/keylayout # vi qwerty.kl
   
9. root@UMI Plus E:/system/usr/keylayout # egrep '#.*(139|158)' *
   
10. Generic.kl:# key 139   MENU
    
11. Generic.kl:# key 158   BACK
    
12. mtk-kpd.kl:# key 158   BACK
    
13. mtk-kpd.kl:# key 139   MENU
    
14. qwerty.kl:# key 158   BACK
    
15. qwerty.kl:# key 139   MENU
    
16. root@UMI Plus E:/system/usr/keylayout #

Copy the Code

It also goes without root.

It must be one of the two red-rimmed navigation bar settings selected in my screenshot.

The other two cause a key remap which apparently can not be mapped another time.

I have a UMI PLus & also want to reconfigure the hardware buttons back to the stock android, Left = back, right = recent apps. I have tried both methods, using apps (remapper etc) & also via Accessibility but they remain as shipped.

Why has Umi done this, seems like a bizarre move to change the recent app button to Menu settings???
