Power/lock button doesn't always work - Nexus 6 Q&A, Help & Troubleshooting

Hi everyone, my Nexus 6 has been behaving weirdly from a week or so, I had the same problem months ago but it stopped happening and now it's back again: sometimes the power/lock button stops working. Like right now I'm typing this and I can't lock the phone by pressing the button but I've to wait 1 minute so it locks automatically, I can't keep reproduce the problem it just happens randomly. Another thing I noticed is that once it locks automatically it starts working again.
I'm on chroma rom, lean kernel and flashed viper4android and xposed.

Any way to troubleshoot this when it happens again? Are there any logs which could tell what the problem is when it happens again?

I think the first thing to do would be to diagnose whether it is a hardware or software issue. If you are willing, you could try flashing back to pure stock and see if it still happens. Then you will know whether it is a hardware or software problem.

Happened to me several times on an older version of Chroma. Two versions ago I think. I haven't had it happen since updating to the latest version.

I guess it's a software issue as you're using custom ROM. I'll recommend you to flash stock firmware and see if the issue continues or not. If continues then ask for a replacement

It stopped happening by flashing the latest Chroma build.

Nevermind it still happens from time to time.. I really don't know what is causing this
Which logs could give me an int?

I have this same problem with mine. I thought maybe it was the case... And removing it seemed to help but it would still do it without the case. Its very rare. My gut instinct tells me its software. If it were hardware I think it would be more pronounced.
I will continue to monitor and update this thread.

Which rom are you on? I tried switching kernel by using Franco's but the bug still happened

My own stock based ROM. I think its a firmware flaw.
Only happens rarely.

I had gotten rid of it for a while with a fresh install of chroma but I had to restore the phone to stock and then reinstalled the largest version of Chroma and its back with a vengeance. Seems every time I wake my phone from deep sleep there is a couple second delay before the power button turns the phone on.

Disabling ambient display altogether seems to have fixed my issue.

You could try MeanPop too, he actually designed the ROM so it doesn't deep sleep just turns down the CPU max frequency and some other stuff.

Check the ribbon connection
Check the ribbon connection from the power and volume buttons.
I had the same issue, but with the volume down button. Tried cleaning the button connection, etc, no success. Then I noticed when I had the back off that the power and volume up buttons would stop working when I wiggled the ribbon. On closer inspection of the TINY ribbon latch, I discovered that the top of the latch was loose, and one of the microscopic metal connection prongs was missing. Pressing the ribbon down on the bottom metal prong from the top with tweezers resulted in a perfectly functioning button. So I carefully bent the prong on the far right slightly to the left to cover the spot where the prong was missing, covered it with thermal putty tape, and reattached the back. So far, so good.
You don't have to remove any screws to do this, but make sure you heat the back cover with a heat gun or blow dryer before trying to remove the back, or you'll likely rip the top of this ribbon latch clean off, because it is in contact with the adhesive on the back cover.

@MZO that's might be the solution. At first, my volume key down wasn't working properly and after dropping it, the power also isn't working. Ribbon cable design is awkward and I am sure it's loose.

Kaiser... Dropped...

OK, so I tried taking my Kaiser out of my pocket and it slipped sending the phone, the back cover and the battery in three different directions. I put it back together but it wouldn't switch on. The green light would blink when pressing the power button but nothing more than that.
I checked everything again including the battery contacts which seemed OK, but the contact pins UNDER the battery seemed a bit flat so I repositioned them. I tried again with fingers crossed and thankfully it came back to life.
Everything seems to be working fine except one little thing I noticed. When I bring the phone out of power saving mode, the clock does not update automatically. It just displays the time the screen went black. One touch with the stylus anywhere on the screen will update the clock. To me this seems like a software problem so I am thinking of reflashing but since this issue started after the fall I am also afraid of an underlying hardware problem that could cause unexpected behavior during the flashing process.
Any suggestions or ideas?

i have a similar problem every once in a while that it takes a few seconds to update. best way to answer your question is to flash the stock rom, if it still does it then its hardware.

[Solved]: Volume key breaking; ? Potential keyboard fix ???

[Update]
Okay, this is bizarre, but I think I have solved the volume key problem. First, I discovered that the volume key problem was oddly related to the USB port. When I put pressure on that port, the volume key would start working again. But I explored further, and it's actually very slight *downward* pressure on the USB port that solves the problem.
So I then just wedged a piece of thin somewhat hard plastic (sliver from a plastic folder) along the top ridge of the USB port, and the volume key now works perfectly.
I think this might also be related to keyboard problems (keys not responsive), because now my keyboard also works perfectly. Can people please test (downward pressure on USB port) and report back?
[Original post]
Hi all - I need help and would appreciate some advice:
My volume key is starting to become unresponsive. At first I thought it was a ROM problem, but it continues with several different ROMs. And if I press the buttons VERY hard, they work.
I presume this is the same basic issue that occurs with the keyboard, but I have it in the volume key.
I am off the warranty. Anyone have ideas/ tricks for how to fix this? I might try a bit of WD-40 for the hell of it.
I have already mapped other keys to control the volume, but I still can't zoom with the camera.
Thanks for any advice.
i too am experiencing the same problem, however i found a solution, pressure on the battery solved this for me....
what i did was put layers of tape on the battery and under the cover...
i guess the hardware becomes worn out after a while, and i dont mean the housing, because i have a brand new housing, i think it lies on the motherboard or the keypad board
this also solves the keyboard letters that never worked too like
m, i and t
HOLY COW, you are right! How did you ever figure that out???!!! So bizarre!
I pressed on the battery and it started working again. Still somewhat unresponsive but definitely better. I'll try your tape trick now.
Spike, a 1000 thank yous! I can't believe there is a fairly simple fix.
lol i figured that out when certain keys on the keyboard wont work, out of anger i tried to put pressure on the bottom slide by squeezing it with a little more pressure on the top and bottom, then the keys worked, weird huh??
anyway, the volume key happened to give trouble too and the pressure fixed it... so, i have some tape on my battery until i can get some spongy sticky tape to replace it
glad it worked for you
Yeah, I had noticed some odd things like when I applied pressure laterally across the top, then pressed the volume key, it would be more responsive.
Unfortunately putting pressure on the battery only worked temporarily, and the tape trick did not work. Perhaps my problem is farther along. But I really appreciate the hint. I'll keep messing with it (till I break it )
For what it's worth:
I can solve this problem by putting the charger into the mini-USB and pushing it in hard while having my finger on the other side just below the volume button. After this the volume button works normally for a while. That's the only consistent fix so far.
So, one thing I can conclude is that it's not the volume button itself, but some connection inside???
I've had my Xperia for a year and 4 months. I'm surprised others aren't reporting this. Anyone else with volume button problems?
I too have this problem, but must be a software problem for me. When I press the volume down button and power on at the same time while the phone is off I do get in the red/blue/green screen.
I have send my phone for repair for two times now because of this problem. When I get it back, the volume buttons are working for two days.
I also have problems with the the following keys: Sym, au, shift, @, Z, X and the blue button. But when I press time for like a 100 times they start working again... grazy

It's tricky sorting out whether it's a hardware or software issue, because it comes and goes. But I am convinced that mine is a hardware issue.
Try the trick I mentioned above. I also just pressed down on the whole keyboard hard in different places. It's been working for 6 hours straight!
[I also wonder if the SE repair people cause the volume button issue. I send mine in for repair 2 or 3 times, including for the same keyboard problem you mention]
See the first post for what I think is the solution to this problem
doesnt work for me... what does is the pressure on the main board
i too have the same issue. pushing down on the usb port seemed to have fixed my volume keys better than adding tape under the battery cover.
sigh.. i don't know how much longer this device is gonna last me..
You need to massage your XPERIA every now and then to smoothen the electricty flow throughout the circuit board. Think of it as a human, hmm... just kidding lol
I've had the same issue and I would like to thank all of you for your valuable inputs.
Alright, fellas, here is what it is. Having the USB port on the opposite side of the keys, means slight pressure nudges the board towards the silicone membrane that is on the inside of the hardened metallized shell that forms the volume key itself. The way it is folded inside means that over time it will mould itself to the housing, hence partial usability problem.
A word of warning: nudging the USB port will dislodge the port itself off the main PCB and then you will have a much bigger problem than partially working volume key.
Tape under the battery cover is a gimmick.

Thanks for the explanation! Although without a diagram it's a bit hard for me to follow. What's the basic problem? The connection to the volume key gets dislodged?
When I nudge the USB port downwards, it's literally about half a millimeter, so it's hard for me to imagine that that could brick the USB port; then again, I know nothing about the internals.
I've had the "permanent nudge" going for a couple months without problems, but I will report back if something worsens.
the presssure trick really worked for the keyboard and volume
i have the same problem guys nd didnt resolve by the methods u told ... plz help me for this
i have the same problem, y buy a new case housing but the problem of the volume key isnt solved changing the housing...i will try some things in the next days..
Another problem that i have is that my usb port doesnt recognize when its plugging in the computer,so i dont have active sync or mass storage,only usb charging...any ideas??thanks in advance!

[Q] Milestone power buttons does not work while phone is on

I can turn on the milestone with the power button but when the OS has booted up it becomes unresponsive, if i keep pressing it it sometimes goes to the power off menu but besides from that it does not work
also i can no longer boot into the bootloader but recovery still works, the last rom i installed was the cronos rom with the included kernel, i used this rom for most of the day and it was fine untill i got home
hopefully someone can help
so...no one has any idea what i can do?
Hi silvacrest, I know this is a very old post (in Internet years), but have you (or somebody else) by any chance found a fix for the problem you described? My Milestone running CM7.2RC1 just started to present those same symptoms.
Thanks!
I have the same problem, started an hour ago, i don't know why, someone please help!
Try taking the battery, SD, and SIM out and using a can of compressed air (NOT an air compressor machine, those pull tons of moisture out of the air and can cause serious damage to your phone) on every nook and cranny of the device. Around and in the headphone port, around the power button, everywhere inside the battery compartment, etc. You'd be amazed at what problems dust can cause.
Thank you for the advice, I'll try that and keep you updated!

Don't recommend this.
You will break the button for good and you'll need to open your phone, well if think you already need to do that.
The milestone button is composed of a thin foil glued to a metallic case, the glue gets old and the adherence with time will decrease and the foil will get dislocated from it's location. This is why your buttons won't work anymore.
If you use compressed air will probably break the button. I have fixed mine by putting a little thin foil of duct tape after I put the foil button in place.
Good luck.
There are more than enough videos out there that shows how to open the milestone.
Hi i2gh0st, in my case, the milestone now sometimes acts as if the power button was pressed, long or short press, waking up the device, displaying the menu or even boot when the phone is off.
You think this behavior could correspond to the foil problem you described?
I don't think so, the button should not work at all, unless it got stuck on press mode. Anything is possible its a ****y button if you look at it from an engineering way.
When I assembled my phone last time I noticed the volume up didn't work, so I opened it again and I found the foil glued to another place instead of its location. So everything started to make sense why buttons break down.
Sorry if I don't really make myself understood, I'm not that good at technical English.
Oky, can't find any relevant video or picture to show you, so I'll open my phone again in week-end after my exam and make a video or some pictures. Just wait a little

X1 closes on any hit or shake

Well, I have a problem which makes the X1 practically unusable. Everytime I hit it with less or more power, or when I move the slider a bit faster, and even when I press on the slider in the opposite direction when closed (like from right to left) it turns off... I got it apart and cleaned every part of it, but there is no improvement.
I can't mention a certain moment in the past from where it started. All I can say is that I have dropped it twice and broke the plastic parts, but the problem appeared some months after, so this may not be the main cause. Also I took it apart once (before it started to turn off suddenly) because the screws that were supposed to keep the slider on it's place went out.
I used it for almost 2 years, but I don't have enough money for a new device (nor a second-hand one like HD2), so if you can even suppose what's the problem, please tell me.
Later Edit: Another thing I noticed after pressing each part of the X1 is that the problem is somewhere in the upper part (near the camera... I noticed it when I tried to pull the stylus and when I pressed the volume buttons...
I'll take the inside out again, now that I know in which side is the problem. I'm on my backup phone right now, so I have nothing to lose... I still think is something wrong with the battery contacts or somewhere near those, so I will check again... I'll tell you if I find something.
Looks like a flex cable problem.

I checked the flex cable, but nothing is wrong with it... It may not be well fixed on the mainboard, and it totally shuts down, not only screen/buttons problems...

Flash Led Just Blinking

Android 5.1
Build Su 4tl-44
Camera app version 5.0.21.2
Flash led on my recently bought Droid Turbo stopped working.
It was OK for 5 days. At one night I tried to switch on the flash light to use it as a torch. At first it turned on and blinked three times then went off.
Then I tried again to switch on but the right led just blinked once and turned off. Left led do not have any response.
I switched on the camera and take a picture. Led behaviour was same (right led just blinked once for a short time then switch off while left had no response).
Then I changed the 'Flash' settings in camera from Auto to On and again tried to take a shot but the Led behaviour remains the same.
Any help in this regards would be appreciated...
After googling i found a solution that suggested that draining the battery completely and fully charge after that will solve the problem.
However, i tried this method twice but it did not solve the problem.
Moreover, i tried some typical things like uninstalling the updated camera app to factory.
Factory resetting the phone and clearing the cache from recovery.
But none of the tricks solved the problem...
Now Fingers crossed....
Solved
I had the same problem. It was strictly mechanical.
I removed back panel and clear from dust and it solves it. I recommend to replace 2 sided tape too. MOTO XT1254
Two taped

The tape actually MUST be replaced because as you said, the flash is a piece connected to the back casing of the phone. If it's not securely connected the insides of the phone, the points that touch the flash board won't be touching consistently and you'll wind up having to take it apart again. You've got to go the extra mile and buy GOOD 2 sided tape as well.. The cheap stuff turns loose as soon as the temperature gets to high or to low. To many people bring their phones in because their fix stopped working.
While pressing both flash LEDs firmly turn on the torch
