Hi folks,
is there anyone who has enough insight in android's guts to know what we need to do to influence which keys are allowed to wake the phone from standby?
I'd like to remove 'wake from standby' for all hardware buttons except the power button, in order to conserve some battery juice (my phone lives in my trouser pocket and is - probably - constantly being awakened by all of my movements.
So, I'm interested in how the hard/soft keys work.
Any pointers?
thanks,
d.

Tried to turn on my XDA yesteday and the button fell into the device ! This caused not to be able to turn on the screen unless I got a call. I downloaded Vito SystemTools' button maping program which allowed me to make my calendar button (when held down) to turn the screen on and off. The problem is that turning the screen on and off is not doing the same thing as the power button did. I was under the impression that all the power button did was turn the screen on and off to save battery and prevent unintended input. However, now my battery dies in 6-8 hours of use compared to the normal 2 days. Obviously, there is somthing more that the power button does.
What I'd like to know from the developers is if there is a program called by the power button and how I should access it. The button mapper program allows me to map any program I want to (almost) any hardware button (not the volume button). If it's a DLL or somthin I can probably write a wrapper program for it with some pointers.
I'm also in the market for a dummy xda or just another power button if someone has one just to get it to look better. However I like the functionality of holding down the calendar button for 1 second to turn the device on/off and would like to keep that permanently.

The power button is probably hard-wired to some processor wake-up logic. So when you turn the processor off, it's going to be very hard to make it wake up by anything else. You could write something that makes it wake up very very momentarily, say every few seconds, to check for a button-press. But my guess is what you want is a new power button.
damn Well i'm waiting on a dummy phone auction unless anyone over here has one to sell me.
I got exactly the same problem, the only difference is that i managed to get it back and i putted some silicone glue in it. It works and don't ask me how ;-)
Anyway, why don't you just press on the call - hang-up , calendar, volume button to wake the phone up?
Than just change the settings in battery power to make it shut down after 5min or 10min. It should help you reduce your battery life time since the phone gets automaticly in sleep mode after that time.
good luck,

I have my phone set not to wake up without the power button being pressed. I can turn this off but then buttons get pressed in my pocket since I don't like belt clip holders.
Does have anyone similar problem?
I figured out that my backlight goes ON very often while I carry my S740 in the pocket. It's because ANY key can turn on backlight while phone is locked up.
I don't really like this behaviour and would like to set it up somehow so only some key could light up backlight. Best solution for me would be:
Power button: Turn backlight instantly off and lock the keys (I have it set up this way already by AE Button)
Power button again: Turn backlight on and unlock the phone
However, I can't really find any good solution, and I guess it's not even possible.
Any ideas?
Hi,
When doing a long-press on the power button of my Galaxy SII, after a few seconds, it powers off. This happens whether it is locked or not, and without asking for confirmation on the screen.
I'm using a Sena leather case, which presses on the power button. Each time I put it in the case, it powers off, then it restarts, and stays on "enter SIM pin code" screen. I may have discovered a new way to switch to Airplane mode but I'd like to avoid that.
Moreover, there is a distinction between :
- long press (2 seconds) : brings the power menu (Airplane / Reboot / Switch OFF)
- very long press (approx. 8 seconds) : switches the phone OFF
Also, these two keys are active even when the phone is locked.
Here's what I would like to do : disable both the 2 seconds press and the 8-seconds press when the phone is locked
I found some threads about key remapping applications or direct edit of keymap files, but none of them were successful.
Could someone point me out an application / a way to achieve that ? Does someone know if it's ever possible ?
(For now, the only workaround I found is a hardware one : disassemble the phone and sand the power button to reduce its height, so that it stays inside the casing)
Thank you in advance. Kind regards
My old HTC Hero used to do that too, which leads me to believe it is something hard-coded into Android itself. I'd suggest there is nothing much you can do, but wait and see if a dev replies or something.

I don't know if it's possible but if it is it has to be something in the kernel.
The 8 second power off function works the same way as the on on your PC and is used if your phone stops responding so I don't see a way to disable it with an app because it's ment to turn the phone off even if an app freezes your whole phone.
Hi,
If the 8-seconds press is hard-coded, I think precautions should have been taken to avoid unwanted power off each time you put the phone into a leather pouch !
On iPhone f/ex, you have to press both power and home button during several seconds to trigger hard reboot, which makes unwanted action hard to happen unexpectedly.
It's always frustrating to encounter such a basic problems on a $600 phone using the latest state-of-the-art technology, which powers off each time you put it into your pocket ;-)
I hoped some developer has found a way to workaround this. I googled a lot, but I didn't find anything.
So, if the power button features are hard-coded, the only solution may be to hard-remove the entire power button
Problem solved.
I disassembled the phone, I removed the power button, I carefully grinded it to reduce its height, and I put it back into the phone.
(For those who may already owned an iThing, disassembling a Galaxy SII is very easy, it's a matter of seconds with a good old mini-screwdriver; proceed carefully when grinding, because if you reduce the height too much, the buttom may break)
Now my power button height is just below the casing. It's still possible to press on it with a finger, but it does not press by itself when putting the phone into my leather pouch.
Thank you for explaining it I had an issue with my S II and it went to service to solve it, they totally changed the board and was shocked when I found the short press on power button doesn't show the power menu I used to have and it switched off immediately!
I've got to return it to service and your post made me thinking it's a simple issue! It won't take time
Regards,
Hi everyone.
I just wanted to ask if somebody knows a way to wake the phone (display) just with the home button? My display is often turned on by the power button unintentionally because i always cary my phone in my pocket. The home button on the other hand is well protected by the samsung flipcover i'm using. so, if there is a way, than i could save a lot of screen-on-time and therefore battery.
My JY HU has no physical clicky buttons, just touch sensitive buttons. On the rare occasions where Android crashes, it needs to be rebooted which cannot be done without turning off the ignition as the front power button just puts it to sleep.
To get around this, I want to install a physical power switch interrupting the accessories / ignition power feed but I've reached a stumbling block as there are different types. Can anyone advise me which type I need to buy? Do I need an SPST switch or SPDT switch?

You need a SPST. Cut the yellow wire fixed 12V. Keep the switch on for normal operation. Turn off momentarily
for reset.

@CARRisma - if you hide the SPST switch, you will gain the added bonus of being able to disable your head unit when you take your vehicle in for any work or when you need to valet park.
Here's a link to a good switch to hide that I've used on many installs:

Yes, that's exactly what I'm thinking too. I've bought this one:-
