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!

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

[Q] NOVA-could it wake up by pressing G or volume key

Hello,
I am using NOVA V8 and flash the huexxx fix
could I use any script to use the G button or the volume button to wake up my phone?
I tried to read the script and tutorial...but i wonder there is no key 95 which correspond to G button. I tried to make a new script for key 95...but it doesn't work at all.
it doesn;t matter to use G button to wake up, but i really want to use other key besides power key to wake up.
sorry for my poor english

In /system/usr/keylayout edit this file: TWL4030_Keypad.kl (I user root explorer, dont forget to backup!) and change this entry (it is in the bottom for me):
key 95 POWER WAKE_DROPPED
It worked for me.

# Phone will wake up from hitting the volume rocker
ro.config.hwfeature_wakeupkey=1

i sorry to tell you that i don;t know how to do so...
Are there any tutorial to change this value?
Besides, I would like to ask whether we can have 2 or more function on one key, such as G button for both camera and power.
THANKS
Thanks

Check the permissions of the file,maybe it changed, and check the tabs in the file,maybe the spaces cause some type of conflict

[Guide How-to] Replace Recents with Menu

This guide is for the Samsung Tab S 8.4 and should work on all variants.
Keylayout edits:
system/usr/keylayout/Generic.kl
Change key 254 from APP_SWITCH to MENU
key 254 MENU
Then reboot the Tab to take effect.
To regain recent apps I use Nova Launcher, Gestures and Buttons and program my second menu key push to recent apps.
As soon as we have a custom recovery I will have a mod to program long press menu to recent apps.
Thanks tdumham for your help.
Enjoy!!!

confirmed to work with 10.5, had to reboot after edit to take effect.
Thanks!

I noticed with the last firmware update a LONG press on recents will bring up the Menu.

Now that there's twrp is there a zip for this yet?

Sorry for reviving an old thread but this helped me immensely and is a much better solution than the stock behavior but does anyone know what can be changed so that I can put the Recents on the Menu key via a long press? Right now long press brings up Search which I have no use for. With the solution above I can access app options like I want to but bring up recents requires a trip back to the Home screen to take advantage of Nova Launcher's gestures.
Thanks in advance for anyone who can assist or point me to a thread with the answer. The search brought me to this thread to begin with.
