Maybe some peoples reboots are on accident

Yesterday while toggling airplane mode I got a reboot. First yet and it was on gingerbread..i just had another one while accident pressing power for too long..
the phone reboots just holding power even if the screen is off. Maybe just maybe this button is getting pressed for too long I their pockets or just pressing power to toggle airplane mode and its rebooting. Or maybe something with this function bugging out...
Anyone else notice phone reboots just holding power for too long?
Edit:Im almost positive this is what caused my reboots

My phone was on the charger last night only for me wake up and it was off. Full battery when I powered it on.
Doubt its being turned off my accident.

As I said, some people.. Maybe some is legit but others are this issue..
Or like I said, something related to that. Maybe bugging out or something.. Just seems weird that holding power causes a reboot.

A lot of my reboots were spontaneous when I wasn't even touching the phone. Also when it was charging overnight.

Maybe somehow the phone off has a bug thinking the power button is being held in or just that function bugging out when the phone is off...
Dont know just a thought.but I'm positive this rebooted mine.

Definitively not by accident!! And the damn thing reboots by itself every 5mn for a few times while I was watching it doing that while plugged in, then turns off by itself in the middle oh the night, I'm getting another one, and another one until I get a working one with no light bleed. I'll receive my 3rd one in a few days.

Mine just did it again. I didn't have the problem on the stock rom, CM7, EaglesBlood or any other rom aside from the unofficial Gingerbread leak.
The rom itself it very nice considering CM7 has weird issues of its own, but resetting/locking up is a big no-no.
As I said earlier my phone was off this morning after flashing the leaked rom last night. I wiped several times this morning, flashed Eaglesblood, wiped again, and again, flashed the leaked Gingerbread, wiped and wiped again.
Set the phone up but didn't install any apps (testing). Cooked breakfast; fine, watched a TV show; fine, took a shower; fine, got dressed; fine, stepped outside for a second; locked up.
The phone was on because when I pressed the power button the touch panel lit up. The lockscreen showed for a second then went out. Then it was unresponsive. I held the power button down for a few seconds, which turned the phone off, then held it again to turn it back on.
Sucks. Must be the rom. Weird why the stock didn't do it, nor others. Others are claiming theirs are fine.
It is SO weird how these problems aren't across the board and are so random. Everything points to a kernel which wasn't included in the lacked build. Hopefully when the official one comes out, we'll get an updated kernel to go with it.

I think it's the overheating problem. My first phone was very hot and had 3 reboots in 5 days. New one I have has no reboot yet and doesn't get as hot like the other one. PCs get BSOD or freezing when overheating. G2X gets Black Screen of Death and freezing.

This could very well be. especially since a lot of people have reboots when charging and that generally makes the phones temp higher...
Luckily I'm good...

If I had the rebooting problem, I would definitely exchange my device. I haven't had any reboots or freezes though.

U could be right but my phone shuts down a few times right after charging. But then for the rest of the night it won't shut down anymore. Sometimes it shuts down in the middle of the night too, it's very randomly. How do u explain that?

So...How did I brick my N5?

I am not inexperienced when it comes to ROMs, rooting, flashing, etc. Been doing it since my Droid X, X2, Gnex and now n5.
So pretty much I installed purity ROM and franco kernel. I was really tired when I was flashing it last night so as soon as I saw it boot up I let myself fall asleep. The last thing I saw was the setup screen asking me what language to select. I woke up this morning and tried to turn the screen on. nothing. held the power button for 10+ seconds then tried to boot again. Nothing. FYI the phone was fully charged last I saw. I have the heat on so it's kind of warm inside. I left it outside on the patio for about 20 minutes to cool down. Still gets nothing. No response what so ever. No vibration, the backlight of the display doesn't come on....nothing. I tried plugging it in the charger, nothing. The battery icon doesn't show up. The backlight doesn't come on. I left it on the charger for about 20+ minutes. Nothing. Plugging it into my computer does absolutely nothing. It doesn't show ANYTHING connected AT ALL. So no fastboot no adb (cant even get to recovery or bootloader) odin is out too. Literally 100% unresponsive.
Didn't think you could do that to a nexus honestly. Especially after all the hackery I did on the GNex. I didn't even do anything funny. Just flashed Purity + Franco (r14) I was waiting on r15.

Try charging it for a few hours (overnight).
I've seen this happen to a lot of people in the nexus 4 section.

I assume after charging you held the power button for at least 10 seconds?

Doesn't sound like it had anything to do with flashing anything, especially since you saw it go tot he language screen.
You've tried holding the volume keys while turning it on?
I honestly may have just been a faulty battery in the device. ran out of juice fast and now won't charge or power it.
I'd still try more holding power button remedies, etc.
Not sure that Odin would have ever helped you anyways considering this is not a Samsung phone.
Worst case RMA it through Google..

Yes, tried every button combo. True about odin, just making a point that a computer and fastboot/adb/toolkits would not work.

Yep its happened a few times with people with the nexus 4 too. The battery is at a decently high charge and suddenly it acts as if the battery is dead.
I have seen people fix it by charging the phone for a few hours though. Do you get an LED light when its plugged into the wall charger?

Absolutely nothing. Completely 100% unresponsive. I think it's done for.
Edit: Purchased from T-Mobile, not Google directly. I pay for insurance on the device. Stinks, but I think I'm going to have to file an insurance claim

Why do insurance when you can just do warranty claim at the store? Just take it back to them (especially since it hasn't been 30 days yet) and replace the device.

Did you try plugging it into a car charger in your car?
For some reason that sometimes works. I don't know why, maybe higher amperage or something.
You should try it!

This happened with my Nexus 4, All I did was leave it charging and that worked after quite a bit. At the time I re flashed it back to stock, not sure if it helped or not but I never had the issue again.

OP, have you solve your problem? my nexus 5 just dead when I rebooted my phone. now, i does not have any idea to turn it back on again.

[Q] Nexus 5 constantly rebooting at 'Google'

Guys my gf's Nexus 5 shutdown today and just refuses to boot up. It doesn't do anything with any of the keys pressed in any of the combinations that are defined. But once it is plugged in to the charger or USB, the google logo pops up and the phone keeps on rebooting to that logo. If the volume down key is pressed when this is happening, the fastboot mode is visible for a second and the phone keeps rebooting. No action can be done in the fastboot mode due to the quick reboot. I am attaching the video of the problem. Any help guys?

If on battery, then the phone does nothing. If plugged in to charger and the key combination is tried then the phone keeps on doing as shown in the video.

Don't know what's going on.
Try doing that but with the phone connected to a PC that has adb and fastboot installed.

You have a fauilty or a stucked power key.
If it is just stucked then you can unstuck it by abusing the power key or taking the phone apart.
If it is fauilty then you have to claim your warranty.
If you disassemble the phone you will void your warranty

A few days back, she had got the power button fixed because the power button response had become intermittent and the phone was rebooting randomly. She had taken the phone to a LG service center first, but they told her that changing the button or trying to fix it might damage the board and told her to change the board altogether. So we took it to a local repair guy who fixed it and the phone was working fine till yesterday when it shutdown all of a sudden and then the rest is history.
Note: The phone is not under warranty as the phone was bought from Dubai and we stay in India. No international warranty.

Then you have to visit that local repairer guy pay him to replace the power key again or pay LG to replace the mother board.

Yeah the repair guy you dealt with must have fixed the button short-term but in doing so inadvertently caused it to short out. Meaning it needs to go back to a repair shop (better one) and cross your fingers that it didn't short out more important components

Guys please clear my one doubt. If it's the stuck power button, what does it have to do with the phone not doing anything when on battery but decides to go till 'Google' when plugged in?

Did you get it fixed? I have the same issue and I've tried many ways to bring it back to life. My last step will be taking it to the tech support, because I live in Brazil, and I'm pretty sure they will charge me expensively as hell.

Had my Nexus 5 for about a few month now, and have loved it till this morning, it decided to just shut off (full battery too) and i tried to turn it on and it is now just constantly starting up to the "Google" splash screen then shutting off.
Sometimes it gets to the the 4 color circles then shuts off.
I want to enter into recovery mode, but I have no time to click recovery mode as it reboots frequently
One thing i noticed when it did boot up was the power button seems to be extremely sensitive and volatile

I had this same problem.. It constantly rebooted and wouldn't let me get into recovery.. Every time I plugged in the charger it would reboot also. You have to let the battery completely drain.. I gave it a couple weeks.. then tried it again and it worked.

Found a solution
Well same thing started to happening with me yesterday after installing android L's developers' preview in my nexus 5. It worked well for first 4-5 hours but then after terminating a phone call when I put it back to my pocket problem started. I searched many forums for solution then I decided to re-install from image. I connected my phone to My PC (Which had driver installed & fastBoot setup) dramatically my phone started working well. And I detached my phone from PC. So I thought it might solved because after supplying charging. But after 3-4 hours it started again so I directly plugged in to electric socket but it kept on rebooting. Then I turned on my PC and attached my nexus 5 with it. Again it started dramatically.
Still I don't know the exact reason behind it. But good new is my phone is still working since last 16 hours... But I took care of not to launch some apps listed risky for developer's preview. So I thing some incompatible app launch may be a reason... but still its only "may be"

[Q] [Help] Stuck at Google screen

So, today my Nexus 5 crashed while using it normally. It is not the first time, of course, but these specific problem appeared just one time before now. The phone is dead, but just until I connect it to the charger. Then it begins to show the Google screen at the beginning, crashes, and does the same thing again. The time between the crashed variates from 1 to 5 seconds. I also tried to get to the bootloader, it works, but after 1 to 3 seconds it crashes again and goes back to the Google screen, crashing, Google screen, crashing,.... Disconnecting just causes the Nexus to turn off completely, and instantly.
Custom recovery: MultiRom edition of TWRP
OS: CM11S V.1.5
Kernel: big-bum V.28
I googled, but all the people having this problem were able to get into the bootloader without crashing and also their phone turned on without connecting to the charger.
Maybe you guys have an idea what to do?

Might be a faulty power button which got stuck in and is causing reboots. In most cases its this.

This could be right. But why does it only try to boot when it is connected to the charger?

Cause the battery is dead.

It Had about 50% when crashing and I connected it 2 hours to the charger trying to reboot, so this would be very strange.

Strange maybe, but probably the case. All those reboots will drop a battery quick.

But how can I charge it. It starts directly with the booting

Leave it for several hours.... Hopefully it charges faster than it drains.
But it's irrelevant if it's the power button. That needs to be addressed. Trying to flash anything is risky if it's gonna reboot on its own.

Yeah, but how can I check if it's really the power button? And, the worst thing, I can't even ask Google for an exchange because of a crack in the screen.

Go into bootloader mode and see if it reboots. If it does, it's the button. If not... See if its OK a while sitting in that mode. If so, flash stock with fastboot.
That's all I can think to try.
---------- Post added at 05:28 PM ---------- Previous post was at 05:27 PM ----------
Oops, You've done that.
So it's power button.... Or some sort of power short otherwise. But button is the best bet.

Thank you for the help. I will try to fix the button.

SOD - sleep of death

Last few days I've experienced sleep of death. My phone has shut down by itself from standby for 2 times in 3 days. The phone is stock, bootloader locked, running on Oxygen OS 5.1.9. Does anyone have this problem?

First time when I noticed that phone is off I press power button few times and hold it and desktop showed up. Today I was holding power button and the phone booted from the begining.

Well if your looking for help you need to give more details than "it just turns off". What's the battery level? Where you using it? Was it in your pocket? Are you running the latest version of Oxygen OS? Does it happen when it's plugged in? Have you tried to factory reset it?

battery was 80%, phone was on the table, running Oxygen 5.1.9, not happening when plugged in, didnt try factory reset, bootloader is locked, no root.

So... there are some plausible reasons, because your phone doesn't shut off when plugged in:
The battery simply is faulty and you have to send your phone back.
Something runs in the background, and makes you just believe, the phone shut off. Would explain the long holding power button procedure (simply shuts off the phone the hard way and reboots it).
An app is really draining your battery that fast. Bitcoin mining perhaps. Not that good explanation, because you were at 80% you said.
I'd go for #2. Check your apps - maybe there's one, causing this.

I go with uninstalling few apps I suspect causing this behaviour so we'll see what happens next.

Your not alone and this is definitely not so simple as a "faulty battery" .its something in the kernel causing panic and its happening only to certain chipset revisions .we need to open a ticket on oneplus

Got something similar today. 5.1. 9 unlocked and rooted, battery around 70%, same place, time, location etc like almost everyday). During conversations in Messenger and WhatsApp screen went black. I pressed power and I've seen keyboard to input pin with comment that pin have to be inserted after restart (normal behavior after reboot anyway), this reboot took maybe 2 seconds. But screen hasn't responsed for my attempt to input pin. I couldn't do anything). Hard reset (with holding power) solved problem.

If you haven't modified your device (root, twrp, etc) in any way then it's absolutely a reason for a warranty claim.

Device isnt rooted or BL unlocked, all is stock. I will contact Oneplus support service if device goes off by itself again. I've installed latest software update 5.1.11 and all fine for last 2 days, lets hope it will stay like that.
