Just in case anyone might find this useful, I've put together the instructions I found whilst trying to do this.

Finally I can take photos without accidentally bringing up the Menu or closing the Camera App!

First time I've ever posted here, so be kind!

This works in CM11 M6 on Samsung Galaxy S4 (jflte) i9505 - I have not tested with other versions or on other devices.

Make copies of the files you will modify prior to doing this. I'm not responsible for any bricking or faults!

Give File Manager Root Access.

Open the File Manager App, then tap the Menu button (capacitative or onscreen), and tap Settings.

Go to General Settings, scroll down to and tap Access Mode

Switch to either "Prompt User Mode" or "Root Access Mode"

Then...


To add Soft Keys:

Open the build.prop file in ./system/

Add the following line to the end:

qemu.hw.mainkeys=0

Close, saving changes


To disable Capacitative Keys:

Open the sec_touchkey.kl file in ./system/usr/keylayout/

Put a # symbol before the both the following lines:

key 139 MENU VIRTUAL
key 158 BACK VIRTUAL

Close, saving changes


To turn off the Capacitative Key lights:

Go to Settings, Buttons, Backlight

Remove the tick from "Illuminate Buttons"


Reboot and enjoy!

I've got a Verizon Galaxy S4 on rooted Hyperdrive ROM RLS20 (4.4.2). I tried adding the mainkeys line, but after restarting, every couple seconds, it complained the UI had closed. Removing the line and rebooting caused the errors to cease.

I had tried out a ROM called KitPop, which had working soft keys, but it didn't work for some other things I needed. Suggestions on what to do, to enable the soft keys?

This method is not working on Lenovo Vibe X3 (X3a40). Can you help please?

qemu.hw.mainkeys=0
if this doesn't work for you,
try this one :
same thing do this at the end of your build prop.

"ro.show.navigationbar=yes"

(without the quotes)
save changes, before you close.
Reboot.
to disable, just type "no" in stead of yes.
(without the quotes, again.)

hope it works.

or try this :
https://apk-dl.com/[root]-soft-buttons/net.alviano.android.softbuttons
install as apk. this will enable and disable your virtual keys, no build prop editing, this app will do it for you. always reboot after each time you use this app.
hope that helps.
