I'm new here so I don't know if this has been posted before,
I opened up my nexus 7 to find the buttons on the right side, (from L to R Power, Vol up, Vol down) but there is also a fourth button labelled "Key 4" does anyone know what this was intended for?
for those who haven't taken it apart, its location is below the volume down on the right side, there is a small circle that stands out from the rest of the design.
Reset.

I have pressed, and held the button, It doesn't do anything that I'm aware of.
And holding down the power key is reset on android...
It's for factory use.

Was wondering what this was, Thanks!
If you look on the nexus 7 guidebook it shows that hole on the designs but doesn't label it.

Today I noticed that the power button does not work because when I can not unlock, but to remove and replace the battery automatically turns on what I'm thinking is that the power button got stuck
any idea?
Going to need alot more info. Where you running stock or custom rom?
Sent from my Captivate using XDA Premium App
im not running a rom, i stay in stock rom.
all started when I received a text message and read the message, when I wanted to block it and not work the power button. I have noticed that sometimes it works with a few strokes with my fingers but it shows me if I turn off the phone. I believe that the power button is stuck
Sounds like a warranty exchange

when I put the battery automatically turns on, but if I keep pressing the 3 buttons combo I can enter recovery mode, but don't works power button in this mode =/
I'd try an clean around the button and if that works
I am not sure thus will do anything but if you can't get your phone running at all you can try to Odin flash stock to see if maybe it clears the problem. If you cab get into recovery then the power button works for something

Try this. Take battery and sim out. Plug USB in. Hold volume up and down. Put battery in.

Inzombie, what exactly did you do? I have been having the same problem for quite some time...I was able to get into download mode using a program I found on the internet, and I flashed back to stock but the power button is still messed up, it doesn't work at all. What exactly did you do
i know this is an old topic but I have the same problem. I got this phone from a friend and now I cant use the power button. I have taken it apart twice now trying to fix it with no luck. I know it isnt the rom. The button is "stuck" but it still clicks. I know it is stuck because it will never turn off. Once battery is in it turns on, and for 3 button recovery, I only need to hold the vol rocker.
I popped the back off my Nexus 7 and noticed there's an extra button hidden in there. It doesn't do anything noticeable but maybe it can he given a use?

its the google in case of emergency button. pushing it will cause your tablet to turn into a IPAD.. Push at your own risk...

I looked at it closer and noticed it is a reset button, it doesn't do anything when pressed and I'm not gonna hold it down to find out if anything happens. I don't know if it's supposed to reboot it or factory reset it.

I'm thinking a hard reset lol
This has been mentioned before. Its a useless button.
It was supposed to have been the hardware reset button but the components on the PCB were not added to allow it to function. If you look at the rear cover adjacent to where that button is, you'll see there was going g to be a small hole. I guess Asus had second thoughts that people might get the mic hole and the reset button hole mixed up and figured it wasn't worth the hassle.
If you really want to enable it, look at the N7 schematics (in another thread here) and add the parts to the board.

I have already pressed it, held it down, does nothing while turned on and off, not sure what it is for.
Boot to CWM, Advances, Key Test, then press

Hey all,
I want to take a screenshots. I've looked it up and pwr + vol- but every time I try the volume just does down and the phone power menu pops up. I tried searching but I only have access to this phone for a while, so I'm sorry if this has been asked.
Thanks in advance

You have to make sure you hit them both at exactly the same time. I had problems with it at first too. Just hit them both at the same time and hold it down for a bit.
You're pressing them wrong!
Press both together

I flashed ElementalX (been a long time since I've OC'd) and now I can't get past the HTC screen. I hold down the power button and it just blinks to no end. This is why I like removable batteries. Do I have to wait until it dies or what?
Try holding down vol down then power let it blink until it reboots

Try holding the phone under a bright light and vol down power

Can't believe that actually worked. Someone on Reddit told me to so I did. I thought that was for people who had problems in a call or something...

try holding down the power button until the home and back button flash 15 times then let go of the power button, then press and hold the power button again and wait for the home and back button to flash again and it should shut the phone off. then you can hold the power and vol. down to boot into recovery. this happened to me and thats what worked for me. hope this helps

My understanding is that sometimes, the light sensor gets tricked into thinking the phone is in a pocket/covered and locks the screen off as a result. Seems a little odd, but then again I've never had this kind of issue with any other device I've owned, and it seems reasonable enough to believe.
Is Elemental a Sense-based kernel though? This issue has mainly been cropping up on AOSP ROMs/kernels (which forced me to revert to a Sense 4.1 ROM. )

wow i can't believe that did it, thank you! thought i was screwed. tried all combinations of holding power/vol+/vol-... whispering pleadingly to it... sure enough holding the #$%^& thing up to a bright light and vol- plus power did the trick. :good:
Hi,
I bought an Nook HD 8GB from ebay. I can turn it on. But the screen is solid blue. I tried to do hard reset but nothing.
Any idea on what is going on?
Thank you

Power and home is not a hard reset. That is supposed to boot you into stock recovery. Try holding the power button alone for like 15 seconds. That will totally power you off.
Hardware issue such as a bad chip or display device.

Had the same problem on my HD+. Hold down the n and the power button for 30 seconds or so and it will ask if you want to perform a factory reset. Hit power button to cancel and it should reboot just fine
