Extra button on Nexus 7 - Nexus 7 General

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

Pressing it reduces screen separation.

Dead after 3 hrs

Was excited opened the box today and played with the nexus 7 for about 3 hrs. Installed some apps and download a movie. Then the screen went black and never came back. It was charging at the time. Tried holding the power button for 10 seconds and nothing. Called Google they said hold all three buttons, that did nothing. Guess I'm taking it back to game stop. Going to have to wait for another to come in. Anyone else have this issue out any ideas

There was another similar occurrence earlier today. Think it was from UK maybe? Most likely you'll need to call Google for RMA.
Which firmware were you running?
Google said return it to game stop. Gs said they would take it back. It was running the latest update. Bc it ran an update after I opened it

Yup, I had exactly the same problem. Screen froze, flickered and then died completely. Btw, if you press the bezel around the screen is the left hand edge in portrait spongier/less robust than the rest of the device?

Hmm. Don't want to be "that guy" but... You only mention taking it out and playing.
Did you actually try plugging it in?
Edit: Woops, missed it on my phone. If it was charging, I'd advise you to get in touch with google. Try volume up + power for 10 seconds too though, just to be sure.

I hope mine is not faulty, it is on its way.
Similar things have happened on my Lumia 900. It has helped me to plug it in and out over and over and then try the button reset.

After getting an RA from ebuyer, I now have it working again after a number of hours on charge and doing much as txaggies07 quote suggests. I think there may have been a problem that the charge wasn't going through properly yesterday, even though I plugged it in and it registered on the icon top right. Once the screen died there was no response with the usual charging icon even after disconnect and reconnect (I even tried a different mains socket!) However, since I got it to boot again I have had 2 random reboots without doing anything taxing on it.
It is kinda flaky behaviour, but maybe it is worth a shot aklbeach? At least until Monday !

How were you charging? If by computer USB port that's probably why

Mains socket, as stated.

Yea I tried holding the power button for ten seconds and holding all 3 buttons like Google recommended. I already returned it to game stop. Now just waiting on another. It was plugged in to the wall charger. It was showing that it was charging and I tried plugging it in again the next day and still didn't do anything.

I had a similar experience. Played with mine for about 6 hours.
Testing things, trying things out, downloading apps, etc.
Put it to sleep and was preparing for bed myself. After a few minutes
I decided to download one more app. Tried to wake it up, but it was dead!
Tried all sorts of things: long press, pressing several of the buttons, tried
to connect it to PC to see if it would be recognized -- no go
I then plugged it into the wall to charge it overnight to see if that would work (no charging icon showed up)
The next day, still dead.
Called Google Play and they are sending me a new one.
I would say pull the battery for a minute and then plug it back in a try again but i think that might void the warranty. Seriously my G2 does that when its in my pocket sometimes and pressing the power button does nothing until a pull the battery. I'm about 68% sure that pulling the battery will get it to boot again.
Honestly though any electronic device with a sealed battery should come with on of those paperclip hard reset buttons, unfortunately logic fails some time.

No worries, not a waste. I had to check myself when it died. And when it wouldn't charge (did I turn it on at the wall? Maybe the socket is broken? Has there been a power cut? Am I imagining this?) Weird thing was it came back to life after much fiddling. I now think there may have been a stray piece of plastic or similar covering a pin and blocking the feed.

Button Number 4

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 guess so, Is it possible to add functionality, like a dedicated camera key :silly:

[Q] Does this thing have "auto-wake"?

I got my Nexus 7 three days ago. It seems like sometimes when it's charging and I pick it up, the screen turns itself on. But I can't seem to purposely reproduce this behavior and I'm wondering if maybe I'm just hitting the power button without realizing it. Likewise, once or twice it seems to have put itself into sleep when I set it down. Can anybody confirm this behavior?
Mine has done this with me as well. There was one guy who posted that it had happened to him, but it was to do with a magnetic case. I've not got round to getting a case for mine yet, and there have been times where I've picked it up, 100% sure i haven't hit the power button, and the screen has come on....

This has happened with me too, turns out it was coming on when I left it charging on top of a speaker... Sometimes the screen wasn't coming on at all even if I pressed the power button numerous times.

Funny...come to think of it, the auto-off happened when I set it on my iPad, which is in a magnetic case.
P.S. - Am I allowed to say "iPad" in this forum?

Well when my n7 was switching itself on, it was sitting on a pillow on my bed, nowhere near any magnets. And when it happened I manually switched the screen off, put it back down again, and was able to repeat it again and again. So unless my pillows are magnetic...

That's actually a very good idea, something along those lines, I'd need to bore her with a subject that won't immediately let her know that I'm taking the p155, but having just got my n7, I could maybe just start talking to her all the time about it and nothing else lol

My be your bed company is "magnetic"? kidding!
I got twice this effect when at bed. And I found it perfect to wake the device in the dark because the start button is not so easy to get and very often is opposite to your available finger!
I had that before, but not since I upgraded to 4.2 I think.
It's a really cool feature, I hope Google add it.
I had this happen a few times as well. Try putting your device to sleep and wiggling the USB cable where it plugs into the N7. If you plug the charger in while the screen is off, the screen will turn on. I know mine doesn't have a real solid connection and if I pick it up while it's charging, it will sometimes cause the cable to lose its connection for a second or so and then move back into position, causing the N7 to essentially think you're plugging the charger in. You might see if that's what's happening with yours as well. I figured I was the only one and it wasn't a big deal so I've just been careful about picking it up while charging or transferring data.

When it happened to me there was no cable plugged in, and I was able to switch the screen back off, put it down again, and pick it up and make the screen come on again. Definitely never pressed any buttons or had it near any magnets.
I think it was before I had upgraded though. Some people say this would actually be a nice feature, and until you remember that everywhere you take your n7 away from home its gonna be switching on and of all the time in your pocket/car etc it would be....

I fully agree, but this feature will and must only be for in "home" use. So not active when lock screen is enabled.
When I'm at home is the main time that I do need the screen lock lol, if I'm out it's usually in my pocket.. The auto screen on would be a good feature at home though, I'm just not sure how it could be implemented.
Oh, wait, I just thought of something It's entirely possible right now. I could use my nice new app called Tasker, and set it up to tell the screen to come on when it feels movement. What's more, if I want it to only happen at home, I can tell it to only work when GPS says I'm home, or simpler, tell it to only do it when I'm connected to my home WiFi network. Tasker is a cool app.

HELP urgent ! power button issue

i cant use power button anymore its not working..it started earlier with izs v1 and v1.1 that sometimes it wakes up screen sometimes not then after i suffered with it i flashed many other roms but the problem was there still..so i tried remapping Power to Gkey and i did but sometimes it works and some more times it just doesnt and i keep pressing on it for 5 minz to make it work
i cant use phone anymore..any help? i just want any way to wakeup the screen easily ..i dont care for buttons
I had the same problem with my OB an year ago. Power button doesnt wake up the screen and refuses to work. For me though it turned out that the whole strip joining the earphone jack, the power button and the earpiece had to be changed. Check for the above mentioned points and claim the damage under warranty and let them do the rest if that is the case. Dont let em buttons rot further. Phone might eventually cost even more to repair.

I got the same problem a couple of months ago. If yours is still under warranty bring to repair immediately! When my power button got broken, the whole motherboard of the phone was changed. I'm no specialist in fixing stuff but without warranty fixing it might be quite pricey.
See if it works if you squeeze the phone by the USB port . if so open it up and put something in there so there's a constant pressure in that area. Assuming you aren't getting it repaired

I opened up the phone and put a piece of folded paper basically above the Sim card and beside the camera. You could try just taking the back off and put it in the same place. If just taking the back off isn't enough just open it up

Screen capture issues

Hiy folks.. Picked up the Flex a week or so ago and have a very hard time getting a screen capture using the vol down and power button. I think it has worked one time out of 50 or so. Anyone else have issued trying to capture screen with this method? Thanks.
Works fine on mine. It's a little tricky but once you get the hang of it it's no problem
Sent from my LG-D950 using XDA Premium 4 mobile app
It's tricky, but there's an easy way to do it. Just take a quick memo of the screen. You can just use the pop up semi circle or the toggle. Super easy and works eveytime

Had trouble the first few times, but got the hang of it. I posted my latest screenshot.
G Flex ftw!
I've been using gravity box's advanced reboot menu option in xposed installer to get a screenshot menu option when I long press the power key. I hate how tricky the factory way is. If the developers of this phone concentrated more on these user friendly features instead of bootloaders and patching Loki and depriving us from the full potential of our phones then maybe this thread would never have been started . And for that matter there would have been several happy customers not having an issue with the screenshot nor disgruntled customer pissed because they wanna create a dictatorship over how we use our phones. That I've paid ,as I'm sure many of you had, nearly $700 for. Sorry that rant just slipped out. Lmao
