[Q] How to reboot Nexus 4 when it freezes?

Simple Question I think:
How to reboot a LG Nexus 4 when it freezes. You can´t pull the Battery out. Is there a Key combination to do so?

You hold down the power button until the device powers off.

OK Thanks. I didn´t thought it´s just simple.

Does this also apply when flashing roms and kernels ? I am thinking about scenarios where you have a boot loop after a bad flash, does holding down the power button still work ? This is the only thing holding me back from buying a Nexus 4.

nipe it doesnt work. i tested that on HOX. the only sollution is to go to fastboot and to choose recovery?

That is a completely different device.

Worked on the Galaxy S2 also this way, you can hold the power button while booting (bootloop) after several seconds it completely shutsdown.

It's different on different devices. On HTC it's holding +vol,-vol and power button together. On others it may differ. But any phone with non removable battery has a hard reset button combibation afaik.

I was under the impression that if you have a small phillips screwdriver nearby you can unscrew the two screws on the bottom of the device to access/pull the battery.

Works fine on HOX.
Holding power button has #1 priority.
Holding power whilst in a bootloop will turn off the device, hold it a little longer and it will reboot.
Holding power + volume down takes you to fastboot.

Same as Gnex/ N7 I guess, hold both the volume buttons and power and you're out of any crap you got yourself in.

On the G2x, holding Vol Up + Power does the trick, HOWEVER, there have been times when my phone has froze and that did not reboot my device and I still had to pull my battery...

Ummm, I wouldn't make that kind of suggestion to the people around here haha. The battery is NOT meant to be removed. Can it be? Yes. Should it be? No. Especially not for a reset. You risk damaging some things or wearing down the spring antennae connectors if you are constantly opening it up just to unhitch the battery. I think it is glued in anyways.
Holding the power button on my GS2 always restarts it even if it is stuck in a bootloop. I assume this phone will work the same way.

From what I been reading they are Torx screws.

Many devices with the non removable battery use this - holding both volume up and down buttons and the power button - for performing a hard reset.

Hard reset should not be an issue for XDA flashers!

Hold down power button for ~10 seconds.

Can someone actually reply here who HAS a Nexus 4 and has actually tried whatever combination it may be to reset... rather than people coming and saying how it is on HTC or Samsung or whatever the hell... noone cares about those... the question is how to do it on the N4 and ONLY the N4 along for what IS the correct method, rather than what they THINK it is...
Thank you

Nexus 4 Power Button

I received my Nexus 4 yesterday, but I see that the power button doesn't always respond to my touch. Sometimes, I have to press it the second or third time to make the phone lock/unlock. I understand that 'how much pressure to apply' is a completely subjective thing, but has any one of you noticed this slight issue with your device?

I've seen other people talking about this, I'm not sure if they have figured anything out.
My theory is it's actually lock screen lag that was introduced with 4.2.1. My Nexus 7 sometimes takes numerous pushes. Have only seen it a couple times on the N4, but it is there

it always happened to me because i was 'holding it wrong'.
seriously.. i think it has a sweet spot. remember how cheap this phone is. i havent had an issue with it since i stuck the bumper on. it is immediate every time i hit the button.

Thanks! The issue has started bugging me a lot now. Cos I always hold the phone in a particular way, and sometimes I keep pushing tens of times and it doesn't come on. I have to deliberately and consciously apply a higher amount of force to make it 'click' and 'turn on'. All the other previous clicks do not seem to do anything. Just wondering if I should send it back, or just buy a bumper. If at the beginning it is like this, I guess after a few months of use it would need even greater force.

install a custom rom and use volume unlock

This has always been a questionable design on Nexus devices. "Here we have a button that is undoubtedly going to be used thousands of times, so let's make it small, and not very positive" .
The button on the Nexus 1 was a joke, S and Galaxy were better because it would have been hard to make them worse. Like its predecessors, the design on the 4 can make it more difficult than it should be to make solid contact on the micro switch that is underneath as the button floats above it.
Unfortunately, like so many other things, I miss the extremely positive button that has always been on iThingies. Do they have a patent on that or what?
If you're having issues when clearly pressing the button straight on, without any angular force, I'd send it back.

i tend to agree. it almost sounds like you are pressing the button in harder and harder. even more so as it pisses you off. so what was fixable with a case probably isnt anymore. rma it and be careful with the next one.
me personally... i think they should have designed the button to be a touch lower. when i hold my phone as normal it rests on the inside of my pinky. when my thumb curls in to push the button in... i am at the very bottom edge or off of the button completely. if i hold it and dont support the bottom everything is fine. and why would i ever want to hold my lifeline to the outside world that way. it is a definite design flaw.

Is there no other way to making screen activation happen through volume control apart from rooting? My nexus one power button is gone and up till now i have not been able to root it because the power button is required to boot into recovery. I don't want this to happen to my new nexus 4

you can try touch control. Needs to be rooted as well and might experience some minor battery drain.

Have you used this without issue on Nexus 4 running 4.2?

I have to agree, the power button is really annoying.

Giving this a try, hope battery drain is better than TC. Proximity sensor wake up working great.

i think im having this problem too.like you said,it has a sweet spot for it to respond.
i have to really press it at the middle,no slightly upper or lower part of the button.not sure if it's manufacturing defect or what,but it bugged me sometimes

Same problem i am facing now
Being the only physical button for power, lock and screenshots the button has become more unresponsive to gentle presses and now requires a great pressure to activate it. Is there any way to fix it before it's too late?

N7 Only displaying battery icon

Hey guys,
Recently got my Nexus 7. I tried turning it on when it came out of the box but it didn't.
So I though I'd charge it for a while. When I plug it in a battery icon pops up for about ten seconds and then the screen goes black again.
I can't turn it on at all. Tried holding the power button for a long time but that didn't work either.
I'd really appreciate it if you guys could help me out rather quickly because I'm on holiday in the US so I've got limited time left to swap it, if nothing else helps.

did you leave it on the charger for several hours? the battery could have been dead.

When I took it out of the box the battery was about half full (according to the charging animation). Now it appears to be full. Left it charging for about 2 hours.
Thanks for the quick reply by the way.

try holding the power button down and the volume down button. see if itll boot into the bootloader. if it does, select start in the bootloader then press the power button to select. maybe itll boot that way.

Not working either. The only thing I've managed to see on my display is the charging animation so far.
Feels like such a disappointment.

have you tried holding down the power button longer than you would expect to hold it down? like 1-2 minutes.

Just held it for 3 straight minutes. Nothing. At one point I thought I saw something on the screen but it was a reflection. Haha.
This doesn't look good does it?

I had a similar issue after a couple months of use with mine. The screen just turned black while I was playing a game and it wouldn't respond to anything. At first I thought it had shorted out or something, and I was considering returning it, but after about an hour of leaving it alone on the charger, it started working again like magic. My friend had the same exact issue. Idk maybe this helps....

you should probably exchange is well you still have a chance. better to be safe than sorry.

If you're feeling froggy, you could check to see if the battery is plugged in. Asus seems to have a QC problem when it comes to connecting the N7 battery.

[Q] green light while charging

hello all
my n4 got wet two days ago. since friday i didn't manage to power it on.
today, after i opened it and put it in a bowl of dry rice (heard it can absorb the fluids) i connected it to the charger and after i pressed the power button for few seconds it the green led light popped, but turned off after few seconds. when i press it for few sec and it turns on and afrterwards turns off.
now it's connected and i managed to keep the green light on for the last 0.5 hour. do i still have a chance to save it and what should i do, or it lost?
i'll mention i don't have an app about the lights and didn't root my phone. i also looked it up in the forum and didn't find a similar problem.
thank you very much for the effort.

You should of placed it in rice has soon has possible.
The green LED means fully charged.
When you mean by turns on do you mean it shows the Google splash screen and if so then when does it come off?

Then it seems that the water damaged some components but somehow the phone does switch on for a bit with a working LED, does the screen light up when switching on?

If I were you I would try rooting the phone and installing Slimbean or another rom that lets you disable the LED light. That could shut it off for good hopefully unless the LED lost all connection to the motherboard and it's only getting power now.

Touchscreen stopped working

So I've had my tf300 for around 2 years and I pulled it out of my bag tonight and the touchscreen has become totally unresponsive. I tried to reboot to TWRP and its still unresponsive and now stuck because I cannot unlock it. Anyone have any ideas what happened/how to fix?

Here is something you can try. Not sure it will work, but might and will sure not hurt.
Find the small reset hole (same side as the volume buttons) and find something small enough to go into.
Press and hold it for a while, again holding for a full minute won't hurt.
Make sure you feel the slight bump when you press the switch, but don't press too hard.
Hope it helps, but no guarantees! Fingers crossed!

I always thought that was a mic hole. Only thing I had that would fit is my nexus 5 sim tray tool but it didn't seem to be long enough cause nothing happened.
