Tips - use G button as camera button / lock screen (change key binding)

I found it in a chinese forum (bbs.gfan.com/android-2014369-1-1.html)
I'm sure most people found the G button useless, so it would be nice to change that. The following is my experience with it:
The position of the G button make it perfectly useful as lock/unlock button, you can use it to shutdown as well, but cannot use it to switch on the phone, I guess it is electrically hardwired to the power button at the top.
Not too bad for camera, long press it will launch the camera app, but it don't have 2 levels so press it once and it will start auto-focus and take picture immediately, similar to touch and release shutter button in camera app, which mean you can't "dis-engage" a failed focus attempt.
here is the method:
1. make sure you have root and r/w to system partition
2. the file in question is "TWL4030_Keypad.kl", it's in /system/usr/keylayout/
3. before making any changes, copy the file to SDcard as a backup
4. open the file with any text editor, scroll down to 3rd line from the bottom, it should be "key 95 GESTURE"
5. if you want to use it as camera button, change it to "key 95 CAMERA WAKE_DROPPED"
if you want to use it as power/lock button, change it to "key 95 POWER WAKE_DROPPED"
6. save the changes, reboot to see the changes.

Very good.
In fact, I may even use this on nova.

the method is work.
after edit file it create backup file which is name "TWL4030_Keypad.kl.bak"

It works! Great!

worked perfectly thx!

thank u..

notice you need to long press to start the Camera App. (you should feel the phone vibrate)
or just start the camera app, then press the G button to take a picture to see if it works.
It should be a pretty straight forward modification.

Could it be
"key 95 RECOVERY WAKE_DROPPED" ???

wow, very nice

Very nice. Thanks.
To all who could not manage get it to work: You must take care of file attributes after modyfing the file content ( otherwise it won't work ). It must be CHMOD 644.
( I use SD Maid for this )

It doesn't work for me, i am using pays ROM. Can someone upload the file? Thank u!

you need to have your phone "root" AND mount system partition as read and write

Hey my phone is rooted, how do I mount system partition a read and write ? Sorry I'm a noob

if you use ES File Explorer, goto setting, select 2 checkboxs "Root Explorer" and "Mount File System"
if you use root explorer, change directory to /system, then press "Mount R/W" button

Allow or Disallow the Home key from waking up the Phone [Galaxy Note]

PREVENT - ALLOW GALAXY NOTE HOME KEY FROM ACCIDENTALLY WAKE UP DEVICE:
Some people complained about the Home keys of Galaxy Note sometime is touched and turned on accidentally when taking it in-out of the pocket.
After studying some articles on-line for Droid X phone (not same as the Galaxy Note), I digged around in the directory system/usr/ keylayout. Finally, I have found a way to do it. I can disable the HOME key from wake up the phone in off-screen state, but still let it to move from apps drawer to standby screen as usual. And I think it works!!
- Goal: Modify 2 file related to wake up function of the Home key (code 102).
- How to:
+ Using Root Explorer go to the folder: system/usr/keylayout, set permission to Mount R/W;
+ Click to select the 2 files: gpio-key.kl and sec_key.kl to modify them. When the menu appears, select: Text Editor to modify the files.
+ Move to the line: "key 102 HOME WAKE" in the 2 files above and put the cursor on the position of "WAKE" to erase the word "WAKE".
+ Press Menu hard button, select Save Changes, the phone will save the backup file and save the current files.
+ Set permission to Mount R/O for the folder: system/usr/ keylayout.
+ Shut down and then restart, Ahh, it worked!
Note: If you want to use Home key to wake up Galaxy Note again, go to delete two above modified files and rename the two backup files to gpio-key.kl and sec_key.
For people don't want to do it manually, I make the 2 flashable files for Allow and Disallow the Home key for Note and tested for working, at least on my Galaxy Note.
The 2 flashable files to do that is attached below. Copy to SDCard/ExternalCard and flash them in CWM Recovery, then reboot:

works for me. thx.

does somebody know whitch file(s) to edit for this to work in Jelly Bean or Cyanogenmod 10.1.
I'm on asylum 4.2.2.this is a cyanogen 10.1 mod , like slim bean .
It looks like we need to change more/other files for this to work , wile when i canche the here adviced ones , nothing seems to change ,, the volume buttens still behave the same.
/system/usr/keylayout/sec_key.kl is changed to..
key 115 POWER WAKE
key 114 POWER WAKE
key 102 HOME WAKE
key 107 ENDCALL
key 105 DPAD_LEFT
key 106 DPAD_RIGHT
key 103 DPAD_UP
key 108 DPAD_DOWN
key 232 DPAD_CENTER
key 116 POWER WAKE
key 212 CAMERA WAKE
look at line 115 and 114 this would change te volume button function in the power funtion , i suspect , AM I RIGHT ????
in fact this does not change the behavior of the volume buttons at all it still changes te volume , btw i did restart after changing te sec_key.kl file
please advice manny thanks in advance

Just tried, and yes it does work on the s4. We only have the one file though, gpio-key.kl. Same location though. Find the line that says home, and delete the word wake. Save changes and reboot, job done!

Lock gear from launcher shortcut

Alright guys,
Pretty much what I'm after is a launcher shortcut which locks our gear.. The reason for this when using custom launchers the home/power button by default does not lock the device anymore.
It seems that particular feature was hardcoded into the TW launcher.
There are various applications available on the playstore, although I haven't found any which work on the gear as they require additional settings to be enabled in a traditional settings dialog.. which obviously we dont have.
If anyone has any ideas please post ! Or even better if you know of a app in mind which works !

1. Push a Root File Manager or adb to your gear.
2. Navigate to "/system/usr/keylayout", Open/pull the "gpio-keys.kl" file.. Confirm any root permission popup's.
3. Modify "Key 172 HOME" to "Key 172 POWER", Using a text editor.
4. Save/Push changes.
5. Restart gear.
I like to use adb to pull the files I want to modify to my desktop, Modify them, Place them on the SDCARD of the gear and then manually place them using a root file browser to their original locations. Also remember to set permissions, Imitate any other permissions in the same directory.

Can you try editing gpio-keys.kl in /system/usr/keylayout
I think that is the file that tells the os what hardware buttons do
btw this idea got me thinking about enabling mass storage, but I had no luck with the couple of apps I tried. I think kernel needs ums module

Genius. Worked a charm.. I sussed the keylayouts out previously.. I was looking at Generic.kl..
Modified Key 172 to POWER and it works a charm.

don't know sorry. but maybe @deepesh.tickoo (author of this nice how-to http://forum.xda-developers.com/xiaomi-mi-3/general/guide-how-to-enable-screen-nav-bar-t2968850) could help you? maybe you just need to change somehow the /usr/keylayout/atmel-maxtouch.kl file?

It's a kernel feature. So your out of luck.
Also you might want to post in his thread as that rom is not here

Alternative method:-
Install xposed framework.
soft reboot.
download gravity box module.(KitKat version).
Activate it.
soft reboot.
open gravity box,
goto navigation key actions
remap keys.
Done.
on phone now,
will upload ss later.

Xposed and lollipop... No way
