[Q] Volume up + Volume down

Hey lads,
this is probably a very dumb Q, but since I am new to all this android schmuzzle and couldn't find ballocks on that, don't judge me too hard ;]
I've noticed that when u press both VolUp and VolDown ( put pressure kinda in the middle or the rocker ) the phone vibrates once and then after several seconds (seems to vary) it vibrates three times fast. Now what the flick is that? Not that much of a big deal but it gets annoying given that even when the screen is off and the phone is locked doesn't seem to give a damn
thanks

has happened to me too but hard to reproduce. I have no ideas why it happens. Sometimes it occurs when the phone is booting up for me as well.

Put ur finger in the middle of the rocker and press ( not even hard ). It happens every time in my case. even when the phone is locked

I get the same behaviour, sure is strange.

Kinda old thread but I didn't want to start a new one either. I've noticed this too by accident. When you turn off your screen and press both volume buttons at the same time it vibrates once and every other time twice or thrice. If it vibrates only once it will vibrate again a couple of times after about 10 seconds. Has someone found a reason to this already?

Maybe HTC thought "Why not? Let's do this and see how they discuss about it." ^^

These buttons are part of combimation of three finger salute (at least look like that)...if you press voulme up + Down and power button, phone will reboot....so might be vibration is just an indicator to show go ahead and press the power button for restart.......Just a Guess

Pressing Volume Up + Down simultaneously while having USB Debugging turned on creates a bug report in the bugreports folder on your SD card.

I can't get it to reboot by pressing the 3 buttons.

This is correct, there's always a new bugreport after I press the volume buttons. I don't think that it's even necessary to have usb debugging on.
Thanks for the quick answers, but could there be something more to it?

Press the power button first and then press volume up and down..you will get a reboot...

Nope, can't get it to reboot. Perhaps this is rom related?

It shouldn't be, but its really hard to get it if you are trying to press three button, you can try power button and middle vol button......any ways I also tried lot of times before I got my first reboot....

1) Pressing both VOL UP & VOL DOWN at the same time = Vibrations & all processes' states and stacktraces dumped to /data/arn/traces.txt (thanks to alind_)
2) Pressing both VOL UP & VOL DOWN at the same time + POWER BUTTON once = instant reboot
Works for me with CM7 and Stock Sense.

Help

My phone reboots and stays at the Samsung log. How can I get it into recovery? I hold volume buttons and then power release, and its still on the logo.

Wrong Section but,
Hold volume up+the main button on the bottom(the home key) and then press the power button until it vibrates, then just release power.

[Q] how to screenshot?

Just looking for keystroke to screenshot on the lg optimus g. After extensive google searching, reading the manual, and inquiring with my carriers tech support I have come up empty handed. If anyone knows you're assistance is greatly appreciated.

Volume down + power

From the drop down use quickmemo or the volume rocker when pressed it is like doing both at the same time
Sent from my LG-LS970 using xda app-developers app

press the volume down button and the power button at the same time. It was a bit tricky for me at first but after a few attempts it become really easy.

Best way is to hold down the volume rocker. +/- does quick note, from there you can just click save. much easier.

Disable Power Button

HI guys,
My power button is not functioning right, so I want to disable it. I thought that there is a file for the power button mapping in system/usr/keylayout from other device thread, but i can't find power button related file. only soft buttons.
Can someone please help?
Thanks.

I partially solve it. It's only disabled when the OS is booted up, so when the phone is off, I can still use the power button. The file I edited is Generic or something in System/usr/keylayout
But another problem is that long press (10+ sec) reboot is still not disabled so sticking power button issue was still annoying me.
However, I kind of got the power button fixed now after keep hitting the power button a lot hard. But I have a feeling it's gonna be back again soon..
Oh btw, CM12 has screen on with volume button feature and double tap notification bar for screen off. So No problem there.

And Cm12 has home button to wake. Only problem can be it wakes up in your pocket sometimes. If your problem is solved, please add "[SOLVED]" to the beginning of the thread title.

Problem taking screenshot

Hi there
When I press Volume Down + Power Button the phone opens up a power menu, where I can choose to shut down, restart etc.
I want to use the default feature of this key combination to take screenshot, I have checked the settings and couldn't find anything that would help.
Would appreciate your assistance.
Regards

Just click and release both Power and volume down buttons for screenshot. Don't press and hold.

or activate hand swipe or use s-pen. Most often I use s-pen so I can make notes.
