[Q] Disable hardware buttons

DerGreeny · Feb 26, 2014

Hi,
I would like to disable the hardware buttons from my Galaxy Tab 3 7.0 since I already made the softkeys visible by changing the /system/build.prop file.

I found HowTo's for other Samsung devices. All of them proposed a modification of the /system/usr/keylayout/Generic.kl file by deactivating the mappings for the keys 139, 158 and 172 (see this thread). Unfortunately, this isn't working for my Tab 3.

Can someone give my advice in this topic?

Thanks in advance,
Greeny

I added qemu.hw.mainkeys=0 to the end of /system/build.prop. If you are interested in the source I could post a link, even if I'm not sure whether external links are accepted.

I've got mine disabled and all you do is put # in front of the key mappings.

What I want to know is how to switch the back key (which defaults to the right) and the menu key (which defaults to the left). It's a pain to have the back key on the right.

Anyone know how to swap them, I've tried different steps for galaxy devices and nothing's working.

Thanks for your answer, but this isn't working for me. I prepended the 3 lines with a # and rebooted the device. But the three hardware buttons are still working

Do you talk about the mappings in the Generic.kl file? I just opened the other *.kl files and noticed keymappings for the same keys in many other files, like vnc-kbd.kl

Open up sec_touchscreen.kl and place a # in front of key 139 MENU and key 158 BACK.

This will disable the Samsung buttons.

Thank you! The back button is disabled but the center Home button is still working. Any advice for this?

When you added the soft keys did it make the launcher bar at the bottom move up and overlap the page dots for the home pages? I turned them on in gravity box and thats what happened.
Thanks

The soft keys do not overlap the page dots, but they are now really close (see attached screenshot).

Unfortunately they stay at the bottom and overlay the lowest row of icons.

ok good to know, thanks.

I am having some issues with overclocking here on stock ROM so need to consider switching to custom, since as rooted I won't get official update anyway

the major thing with custom is that there is no multi-window available which I heavily use .
