This is such a simple (but useful) mod I'm surprised it hasn't been posted.

If like me you only use the home button to wake the screen, and don't want the power button waking the screen whilst in your pocket or when you try to adjust the volume. This is for you.

You need to be rooted and need a file manager that supports root (Root Explorer or Root Browser (LITE version works fine)).

On your phone navigate to system/usr/keylayout
open sec_key.kl in text editor (you can make a backup if you want by adding .bak to the end of the file name and saving - Root Explorer will do this automatically)
delete WAKE from either HOME or POWER (not both!)
save and reboot.

is there any setting to disable "back" button? I find the back button annoying when we are using s-memo, as it oftentimes accidentally activated.

Yes, in system/usr/keylayout
sec_touchkey.kl

I now have my back key set as SEARCH and use LaunchKey (paid version) to remap long press search as back. It works quite well, as search does nothing in most note/drawing apps.

market.android.com/details?id=com.beansoft.launchkey&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5iZWFuc29mdC5sYXVuY2hrZXkiXQ

Hopefully someone will figure out or develop a better way.

Thank you for sharing this! Now for the not so bright question: does this mean if I accidentally hit the power button when making a call or playing a game, I won't be able to turn off the screen anymore?

TIA.

I disabled the wake for power button, it works for a sort press, but long press still wakes.

Any tips? I think this will avoid pocket button presses.

thanks

Edit= never mind, I didn't reboot, works now.

found the solution, using buttonremapper I switched the menu and back button so no need to buy launchkey. now if i accidentally press the right button during using s-memo, it will not activate the back function but menu function, so can easily cancel without the apps closing.

Thx for your answer. ES File Explorer (in root mode) only start from the /sdcard/ directory, and doesn't go upper. System's directories are above if I'm right.

Why the hell root explorer tell me that this file (sec_key.kl) is write only protected (why as he is root too, he can't write on the file).
Others in this thread have try this whit rooted G Note XXKKA / CWM without problem, I don't get it... :confused:

Great hint, thank you!

Had some trouble getting the sec_key.kl edited though: Root explorer didn't want to edit / save changes / change permissions / create a new file (even on external_sd!). No idea why. My Note is rooted (obviously) and Superuser reports SU granted when I launch RE.

To finally do it I copied the file to the external_sd using RE, edited it using ES, moved it back to system\usr\keylayout (which strangely enough worked) with RE, adjusted the permissions (wich, again, strangely enough now was possible) with RE, rebooted.

    For sake of keeping this post up to date, in the ultimate bean rom you can do it the way it's described in the start post again. The file name just changed to gpio-keys.kl

    I know this is an old thread but I just tried this in the sec_key.kl file on Android 4.4.2 (kit kat) on Galaxy S3 and it had no effect after reboot. Anyone have directions for kit kat that work? I don't see a gpio-keys.kl file anywhere. Thanks!
