[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.

Power button not working

Just recently my power button stopped working. I pushed the button to use my phone and it did nothing. For about five minutes pressing the power button did nothing. I had to press and hold up and power button to restart. Is working fine now but What I would like to know is why did this happen? How can I prevent something like this occurring?

I've noticed mine has done the same thing a couple of times since I've gotten it. In my case I think the phone hot boots, maybe you have the same case

Same issue but no case and it wasn't hot. I think it might be software related. Waiting a few minutes and holding the button for 30 seconds finally allowed it to boot.

I've experienced this just once with the same result. Power button + volume up resolved it.

I had same issue pre-root and vol up and power fixed the issue. No power button issue since.

hold the power button at the same time as holding volume up button.... hold both for a few seconds might take as long as 8 seconds
will put you in fastboot mode....(if it doesnt go into fastboot that way can hold power button until screen turns off then quickly hold volume up until fastboot comes on)
once in fastboot tap volume down twice (slowly allow a slight pause between presses) then pres the powere button and you will be in recovery

I can't even get my phone to the fastboot screen. Ive held down vol up and power. Vol down and power. All 3. I'm really at a loss. Any ideas before I just get a replacement? Also, my headphone jack has seemed to stop working along with my power button.

Open rear case carefully and see if you can turn it on

Hello,
I am facing the same issue..the power button isnt working.
Hence i cannot restart/unlock /power off my phone.
Is there any alternative?
Please help ASAP.
Thanks!

Press volume buttons and plug in the charger. Phone will start in recovery mode. Select normal and your phone will start.
Once your phone is running, download power to volume button app to unlock the phone using volume button.

I tried holding both the up and down volume simultaneously and inserted the charger, I get only blue battery icon and after the screen blacks off. Pls help.

HTC One M8 stuck in boot loop, won't power off

Hey, so I was messing around with my phone and using TWRP, I deleted the original ROM and then, having forgotten that I'd deleted the ROM, tried to reboot the phone. My phone is now stuck on the HTC splash screen (which at the bottom has the text "This build is for development purposes only...") and won't turn off, despite me holding the power button for probably 1+ minutes. I'm planning to wait until the battery dies, then once I can boot again try to get into TWRP by holding the power button and volume down. Does anyone know if there's a way I can get to TWRP without having to wait until the battery dies (my phone is at full charge), or whether this will not work and I should try something else?
Thanks in advance!

Press and hold power & volume up buttons until the screen turn black then release both buttons and quickly press & hold volume down button only. This will get you to hboot

Question Black screen but still working. How to shutdown phone

Hi,
My Pixel 6 Pro screen went black, but I can still hear and feel that the phone is working. I used the volume up + power button to reboot it and now I touch the phone and I feel it vibrate as it's registering the touches. I also see at the bottom of the screen some white stripes flashing. It seems that the screen is damaged and I need a replacement screen.
Now my issue is that I can't seem to turn it off. As the screen is black, the only way to shut it down would be with hardware keys. But up until now, I haven't been able to figure out a way to turn the phone off.
Does anyone know how I can turn of the phone?
To replace the screen, obviously I need to turn it off first...

Usually long pressing the power button, but it may be different. As long as it gets fixed within a month or so it you can let it discharge until it auto shuts down. If more than a year old replacing the battery when repaired is a good idea anyway...

I tried long pressing the power button with no luck.
I tried volume down + power button for 20 seconds, didn't work either.
I tried volume up + power button for 20 seconds, this I think reboots the phone.

Power button only might take 20 or so seconds.
Otherwise just like it sit until repaired.

Power button + vol up + vol down. Keep holding down once you feel the phone vibrate. Takes you to the bootloader screen

The battery died.. so that's good!
Thanks anyways
