[Q] galaxy nexus power button problem

Ok so iv had my GN for four days now and its developed a problem with the power button.
Sometimes when i try to turn the screen on via the power button it wont respond, at first. It happend last night for the first time, i tried to unlock it and nothing happend, then after trying about 5_6 times it rebooted. Same thing happend this morning.
Has anyone else had this problem?
Does anyone think this could be software or hardware issue?
The phone is completely stock running 4.0.1 on tmoble uk.
Anyones help or opinion would be appreciated.

Try updating to 4.0.2 before you write it off as hardware problem.

Thought about that but it would mean rooting , my fear is that it becomes permenant , then my warrenty would be void , i did have it on face unlock when this was happening i have now changed to slide and as yet ive had no problem , i will post here if the problem is fixed for anyone who is interested

I thought the stock build is 4.0.2?
Have you tried pinging for an update in the settings menu?

Rooting is not permanent. You can remove it by delete the SuperUser apk and binary; that's what root is. Or if you're paranoid, flash a stock image.
Then lock the bootloader. Hooray, your device is stock.

Yeah i do understand that, my fear is while rooted that the problem becomes permanent (at least for me) then while off for repairs they see that its rooted and tell me to get lost!
Iv had a few problems with this phone like locking up while adding widgets to home screen, locking up half way though a phone call, browser hanging all the time and of course the power button all of which resulting in a battery pull.
Id come to expect this kind of behavior over the last year & 1/2 from my hd2 as it wasnt ment to run android in the first place, but this is a google flagship.
Maybe i just got a dud or maybe its the stock 4.0.1 has anyone on custom rom had any of the above problems?

i think the point is that you can unroot it and they cannot tell the difference that it was ever rooted in the first place. and get your warranty fix.

Yes, but his point is if the power button becomes unresponsive while he is attempting to root/unroot the phone then he wont be able to complete the process.
I haven't experienced anything like what you're describing on my Galaxy Nexus, even while I was running 4.0.1. Does the power button only become unresponsive when you're turning the phone on/off? Or does this happen while trying to lock/unlock the phone as well? If it only happens while you're using the face-unlock feature then it could be a software bug and flashing could fix it...
I would call either Samsung or your carrier about it before deciding to root/flash it myself. Perhaps your carrier will just switch it out for another one they have in stock.

I have experienced this problem as well with the power button. I have the GSM version and I haven't received the 4.0.2 update but I did receive the ITL41F update. After about three or four presses of the power button it becomes responsive again. I think you might be getting the resets if you press the power button repeatedly without waiting a few seconds I'm between presses to get it responsive again. I also do not think it is hardware related and may be some kind of software bug. I am waiting patiently for the updates.

yes thats exatly my point, although i really am leaning toward software as tk123456789 pointed out if i wait a few seconds it will come on though only after i got rid of the face unlock, using face unlock it was a lot worse. Im thinking if it were hadware it would either work or not,
BTW this problem is when i unlock the phone and not when turning it on, i dont think i made that clear.

my power button has stopped working....it only works sometimes but it usually acts like im holding it down....if i pull the battery and put it back in, it boots up by itself and i dont even press anything...idk what to do and im freaking out

I wonder if this is becoming a known problem with Samsung devices. Do me a favor and shake your phone a few times. Try it every now and then until it wakes your phone or the power menu pops up. Means the switch is busted and the contact is floating around. This is what was going on with my Captivate and I haven't found a fix, nor do I want to solder on a new power button.

I left it in rice overnight and now everything is working perfectly! Hopefully it stays that way! It may have gotten wet from my XO skin application! Never ever ever again with a wet apply! NEVER!
Edit: its still doing the same thing again...spoke too soon

I got my GSM Unlocked Galaxy Nexus from the Play Store two days ago and am experiencing the same issues with the power button. It worked fine for the first 24 hours.
I'm on the phone with Google right now to get a replacement phone which is nice because they're contacting Samsung on my behalf.
(I'm within the 14-day replacement policy for new devices)

Flash manually the official 4.0.4 IMM76I.. And relock your bootloader after that and try.. Thats it

similar Issue:
I bought a used, rooted Galaxy Nexus. Due to my own (drunken) stupidity not long after my purchase I caused a scratch on the glass covering the display. As I did not want to pay for a out-of-warrenty repair, I left the device as it was.
Some time after, my power button became unresponsive. As it took 3-5 presses to activate the screen I installed the app "PGM Galaxy Nexus" that allows to wake the device with a swipe gesture. Not to long after, the power button stopped responding all together. While researching a permanent solution, my battery died.
In order to be able to use my phone as soon as possible, I brought it to a local (and unfortunately, unauthorized) repair shop. The repair shop tested quicky for any further defects (by plugging the phone into a wall charger - I had done the same at home) and quoted me 50€ for the repair. Some time after, they emailed me that the replacement of the power button did not repair the device. They said however, that the "main power supply IC" is most likely at fault and that a replacement would cost about 120€. As I could not find this chip in the teardown pictures at ifixit, I am not sure if I should invest further trust in the repairshop. In addition and as writen above, charging the device was no problem at all. In fact, I charged the battery that was in my Galaxy Nexus to 100% before bringing it in.
This is where my questions start:
1.: Is a defect of the "main power supply IC" a known defect at all? If there are known defects of the "main power supply IC" are those defects linked to a faulty power button?
2.: Currently, my plan of action is to collect the device and contact Samsung to have it repaired by Samsung itself. Does this mean sending it in? Do they have authorized repair centers like Nokia used to have (NSC) where I could just bring it in?
3.: What might the cost of the repair be? Can it be noticed that the device was opened before? Is root a problem when sending it in for repair?
I would be greatly thankfull for any device and in case I forgot to provide any details, please feel free to ask.

[Q] Broken Power Button - Interesting Issue

So I purchased my GSM Galaxy Nexus in March of this year thru Amazon. From a Samsung seller, Yapper Wireless.
My power button has suddenly stopped working, don't know why as I can't even remember the last time it's been outside of it's Otterbox. There's no moisture or anything, it's just stopped responding. I've been able to set it up in AOKP so my volume buttons wake the device but it's just a pain to live with.
I call Samsung today since they have a Limited 1 Year Warranty on defective Hardware. Apparently per my IMEI number my Galaxy Nexus is an International Galaxy Nexus, and the only place I can get them to fix the power button is by making an International Call to Samsung Europe and sending the phone to Europe???
The Girl was no help, I'm trying to explain that it's just the power button this is a common issue apparently. Nope gotta make an International call and ship it to Europe.
Anyone else have this kind of issue with repairs for the phone and have possible some kind of workaround getting it repaired with Samsung? Like I said I'm living with it for now but it's just a pain.
Thank you

As an update, I called the Samsung Repair Center in Europe from my work phone since we have international calling. They won't take the phone because I'm in the US and there's potential problems returning the device to me. And Samsung in the US won't fix it because the phone is from Europe.
Well played Samsung.

The paid version of PGM app lets you lock and unlock your screen using swipes on your screen. Have you tried that ?

+1. Highly recommended. My power button isn't dead (yet), but I have to press down on it until it feels like it's underneath the housing to get it to respond. Been like that for a while now, but it hasn't got any worse because I have been using that app. Swipe halfway down the screen from right to left to wake, across the bottom from right to left to lock. If the screen times out a simple tap wakes it back up without locking. You can also customize the gestures so you can swipe it wherever you want. It also has very very very little drain on battery, if any at all. I still consistently get 4hrs screen on time with a 4G connection 100% of the charge, GPS, sync & sometimes Bluetooth ON. Stream Pandora for a bit as well as YouTube, Facebook and XDA browsing. That's getting off topic though. This app will take that pain you're suffering right away. Totally worth it, check out the reviews on play store. PGM Nexus

Well for now I've set the timeout on the screen to 15 seconds and use the volume buttons to wake it up. I've worked around it already it's just a pain to have it broken and the manufacturer stonewall me on getting it fixed.
My T-Mobile contract is up for renewal right now, looking at the Nexus 4, but it's LG...

Worse case, power buttons are inexpensive and I don't think too difficult to replace. Good luck.

Head on over to the N4 forum and see how others feel about it to get a better decision as to whether or not you want it. Couldn't help you there, haven't visited those forums once yet. However in the meantime I would still look into PGM Nexus. I had the free version from day 1 since I bought the phone. Power button started to die so I bought the full app. Now I couldn't really care less about returning it or getting it fixed. It just works, and well. Sets upon reboots too so you don't have to wake it with the volume keys and then turn it on. It's great lol. I swear by it. Also pretty cool because I chill with a lot of iPhone users and they all thought it was cool how I turn my phone on and off.
Apple - Innovating new ways to take your money

I purchased the PGM Nexus app, works really well and I like it for what I need it for.
But the power button is apparently now working fine after over 24 hours of not functioning. I've had some mild panic attacks over it and it just started functioning again. I'll keep PGM Nexus though, appreciate it.

Hahaha I think your nexus is messing with you.

I use pgm nexus to turn the screen on and Standby Touch shortcut in my dock to quickly turn the screen off.. I've been using this setup for quite sometime now to save my power button and I really like it.

Correct, to enter download mode it's that three button combo. That stated, there are other things about which you may wish to ask, such as the receipt, date of purchase, reason for selling such a relatively new device (could be that it's beyond the returned item window), etc.
In a word, if you plan on rooting the device and installing recovery, a blown Knox fuse may be of less concern than a bad tablet (ie, hardware failure).

Check to see if it is running a stock or a custom Rom

Home button stopped working...

I walked in the rain very briefly and have an Otterbox on it... What is the best way to determine that it is a hardware problem and what are my options? (I have the phone for nearly a year, I doubt warranty applies).
I am get pretty tired of using software home button. Note - button doesn't work in recovery mode either.

The warranty is for a year. If the Knox bit Is tripped it's said warranty is voided. I've seen many members who have had Hardware issues repaired even with it tripped after flashing back to unrooted stock. Call samsung support... Don't mention you are rooted if that's the case.

On the fence

I am wondering about the lg g4. The phone seems really good. But I have a couple concerns. Did you guys get used to the buttons on the back really quick? They seem really weird to me. Also, I want to buy the h811 model. How easy is this model to root/ROM?

The buttons are great. Very convenient. The phone overall is very good. Root is easy if you know what you're doing. Currently on the 10n software, you have to flash the rooted/patched system partition. Then you can flash TWRP via adb shell.
Edit: for 811, rooted system:

I tested it for the insiders back in may literally four hours after taking it out of the box for found myself pulling my z2 out and trying to tap the back to turn on
Now when I pick up my tablet I keep reaching to the back without thinking
So for me it was easy but my wife doesn't like it but loves tap to sleep/wake and she automates her volumes based on time so she only touches them if it runs out and she has to boot back up
We have the unlockable h815 so can't say about root

Hi, I have had the phone for a few days now and can honestly say the buttons on the back are a great feature. If you hold a phone like I do either with left or right hand and the bottom corner of the phone resting lightly around the fleshy part of your palm, your index finger will automatically go to the buttons and they are very tactile, so without any thought you know the up or down and power button. It has been hit and miss on other phones for me with rockers etc, and during certain operations rockers on the side just get in the way, so buttons on the back for me is an actual improvement and keeps build up of dirt in those places to a minimum.
The phone straight out of the box comes with double tap to wake/sleep functioning, so I mostly use that to turn phone on or off anyway. I also use knock code which again functions when the screen is off. If you've had a phone before rooted and kernal added this function, you'll know just how useful and easy it is, the knock code addition is a very clever way of adding to this feature in my opinion as it doesn't have finger print scanning, which still takes seconds to register so no big deal.
I don't know about root etc for 811 as I have H815, but just having a quick look there are methods on these forums.

I am still using the G2, before that I had the HTC One X. From the first day that I had my G2 I loved the buttons on the back, the double tap to wake is awesome.
I want to get This phone, but not being able to unlock bootloader means no CM / Vanilla, will be getting the H815P.
I have the luck of having the same phone for 20 months before I can upgrade. I can upgrade today, on my way out soon.
I really have fallen for LG, If South Africa had the nexus phones available on contract I would get one.

Unless you get the H815 there is no Roms/Recovery or Bootloader Unlock. Only root is available for other models which was fairly easy to do.
The button placement is the best place ever and I wish all manufacturers would transition to do the same. No more accidentally turn on the phone if you hold it a certain way or grab it from your pocket. Asus is also placing the buttons the same way as LG. Double tap to wake / turn off the screen is the best.
I would definitely opt for the LG v10 if you don't mind the phone size difference. Every reviewer picks the v10 over the G4 for best phone of the year. Especially due to the video recording issue our G4 encounters. Since I don't shoot much video I could care less however.
