I can't see any similar problems on the forum, so can anyone help?
Yesterday my Kaiser's power button stopped working. In the middle of the day, not doing anything with it, installing anything or changing any settings. I took it out of my pocket and the screen was on with the power off dialog box showing (I normally keep it on standby in my pocket) The power button wouldn't put it into standby, and holding it wouldn't power it down. Intermittently the power off dialog appears on screen, if I click yes the device restarts (doesn't stay off). Everything else seems to work normally still. Soft resetting works normally. All the other buttons seem to work ok. I've tried a hard reset, but that made no difference.
Anyone else have anything like this?

I'm having the exact same problem right now. The power button definitely seems to be stuck. Can't figure out how to unstick it
About a week ago I had a similar problem.
The power button and the photo button stopped working. I couldn't turn the the device off or set it to standby.
Had to soft reset and after that it was ok again.

Anybody having problems with the power button not working?
It doesn't work at all no matter how hard I push. At times it works without issue, other times I have to use the camera button to wake my phone.
Anyone else with this?
Defective unit.

Did you both ever opened the phone, maybe for repair or the.prevoius owner? Maybe check the "outside" when opening phone (and removing LCD) many times the button flex cable gets damaged or get a small crack so it stop working after some time... The button flex is mounted very easily, maybe just need to get it back right into position and make sure it holds the contacts. The whole flex is just 6euro, repairing easy.. Just follow "ifixit"

I had a problem with the power button on my phone recently. It was off, just like you describe, guys.
But the combination: power button + vol UP, to force a reboot of the phone worked and after booting, the button was working and the problem never occurred again.
So this morning I picked up my Note 4, used it normally to check emails, etc, went to turn off/lock screen and it wouldn't respond at all. I held down the power button and then it brings up the power menu, I restarted a few times and still nothing. Is my power button defective or could some setting have automatically changed the settings?
Go to *#0*# and select Sub-Key. Press every physical button on the Note 4 one by one (Volume Up, Volume Down, Home Button, Power Button On, Power Button Off). If the end result is PASS, then you're Power button is fine. Can also be a sticky / tacky power button, or something you modded in the settings.

Just did the test, every button turned a different color, volume up (gray) volume down (green), menu (brown), home (blue) back (purple) , power (red, is this a fail?) but I didnt get any PASS. Is the power button supposed to have 2 colors, one for on and one for off? I tried holding down the power button but that brings up the power menu.
Also noticed that the screen will not dim or turn off automatically.
Update: I ended up doing a reinstall of the stock fw through Odin and it fixed it. I wonder what caused it and where those settings/issue where stored? I had tried doing a reset from within settings, but as I understand, that doesn't clear ALL the data.
I know how it feels when the diagnostic doesn't yield a pass. Glad to hear that reflashing the stock firmware resolved it though. Could have been something deep in the firmware causing this. Keep us updated if it persists again. The power button has been a culprit of problems in the past for many as well in previous Note devices. The final result should have displayed "PASS" on the display, perhaps you didn't complete the task, that's okay. Sometimes simply clearing the cache instead of factory reset could have resolved the problem as well. Samsung is notorious time to time.

I have a Note 4 too and since a few days I have been noticing this issue. The power button doesn't wake the screen up. I have to fiddle around the button a little bit, press it a bit harder sometimes and then it works.
Also noticed that when this happens, I unlock the phone using the Home button and when I try to use the power button then nothing happens. Keeping the power button pressed doesn't give me the reboot/boot options either until I fiddle with it.
The strange this is, one it starts working, i can use it again and again until I leave the phone aside until sometime and then the power button does nothing until i repeat fiddling it.

Also ran the test : *#0*# and select Sub-Key
All buttons work except the power button but again if I press hard and try to nudge the button a little bit, I saw the colour change to RED. No PASS either.
Do you have any xposed modules installed? I had this happen with either gravitybox or wanam when I tried to tinker with the power menus. *3.
No. Everything is stock and not rooted either.
In my case, a complete wipe to factory fixed the issue for me and never had the issue since then, but it kind of sounds like you may have a hardware issue.
that's what I'm thinking too hw issue. But once it starts to work it works perfectly even pressing the button lightly. If the phone's been idle for a while that's when it starts. But anyway, I'll do the basics, factory reset and then bring it over to the carrier shop. Hate to send it away as its not that long ago i got the phone.
Thanks for all the help/comments.
I just started having the same problem myself. I think I'm going good to buy the right now. For the power button and have it installed.

I am having the exact same problem , did you manage to solve it ?
No. But I've been using the phone less as in on holidays and noticed it hadn't been happening much. If issue still persists I'll bring the phone back to the carrier for a repair/replacement as it's still under warranty.
For the first few days power button worked occasionally now it has stopped working completely.

The working of button changes with temperature. With a little heating with hair dryer the button started working.

I agree with the temperature because when I was in holidays the issue didn't happen and Iwas in a hot country with 35 deg C. Weird, so was my Note 4 built for Middle East?!?
My power button has started working 100% normal from falling the hw test earlier.

I did a full factory reset and it appeared to work but after restoring all my apps and using it for a couple of days it started again. Brought it to the carrier to get it fixed as is still under warranty. They said it was a faulty "electrical component" which they replaced. Got the phone back and I restored all the apps. I have the problem again. I don't trust the carrier to have fixed the issue as it was intermitten in the first place. The button works continuously once it's stays working until I leave it aside for a while. I'll have to bring it back again and wait for a week!
I'll keep you posted.

My note 4 problem is whenever I remove the charger it went out and behave as it wants to start up and as soon as I replaced the charger I can turn it on and it stays on. Someone please help me with this
I'm turning here only because I ran out of ideas to try.
My daughter has a "pure" version and last night at the airport (traveling) she told me that her home button stopped working and notification shade doesn't open past the first card that shows time/date.
I didn't believe it but sure enough, that's the case.
I googled this issue and fond a post where someone suggested to add/remove a user. I did that and the notification shade is back to normal but the home button still does nothing. Anyway, instead of wasting time on this, I wanted to Factory Reset but the freaking Reset button is disabled! Ok, so I did the power button+vol_down combination to get into boot options and when I select the Recovery option, nothing happens! Just a black screen as if it shut off.
Any idea on how to fix this and what could it be? I've never experienced anything like this on any of my Nexuses so I'm kinda pissed at Motorola and will most likely never buy anything but Nexus again.
Thanks
When selecting "recovery" from the bootloader are you using the power button or the volume up button?

Man, that's kinda embarrassing.... LOL
I was using the Power button instead of the Up button. And it's written right there on the screen.
Thank you!
But still kinda strange behavior that I'm trying to fix. Wiping right now and I'm sure I'm all set. Thanks!
Are there multiple users on the phone?
I have the same problem and just started today.
Any thing fix this?
Hello all. I used Lineage OS on my 3T for a while and it worked without issue. After some time I saw that when I needed to restart the phone, I couldn't do it simply as I expected. This was because when I held the power button, I felt the dmall vibration but nothing comes up on screen to allow me to choose if I want to shut down or reboot. The screen just remains the same.
I panicked and assumed the power button was faulty but it works fine in all other areas. In fact if I really long press it, it does shut down the phone (a la a battery pull scenario). And it locks the screen and turns it on as expect too. What could be causing this? I'd really appreciate any help.
