weird phone reboot? - Nexus 6P Q&A, Help & Troubleshooting

so last night my phone randomly froze and rebooted into the command page with the little android guy saying no command. So I had to reboot system and all is well. anyone have this happen to them?

That sounds like you booted into recovery mode. Not sure if this can be done with a button combo or not. If you were able to boot fine, it should be nothing to worry about.
I believe once you see "no command" you can hold power button and tap VOL UP then release both buttons and you will see some options, one of them being reboot, which will go back into normal Android.

Yeah it was recovery mode and it did it all by itself which was weird but no its fine and I got the security update seems even smoother if that was possible

This just happened to my phone at the beginning of a phone call! I didn't know what to do, so I just held the power button down a for a few long presses and fortunately it rebooted. Seems OK now, but leaves me a little worried!

[Q] Nexus S 1st day and its froze, cant unlock

Hi guys, having a problem with the nexus s that i have just got today.
Installed an app for getting wallpapers, something like FLickir HD wallpapers or something.
Set a wall paper, then browsed on through others.
Phone soft rebooted, and now the screen and bottom buttons are totally unresponsive. No idea why, and no matter how many times i battery pull etc i cant get it sorted.
Any help would be a great help.
Can you get into recovery mode?
Pull battery. Wait 30 seconds. Put battery back in.
Press and hold volume up button, then press hold power on button.
Phone should enter Fastboot mode.
Use volume keys to highlight the recovery option.
Use power button to select it.
Once the phone starts to reboot you'll quickly see a little box pouring an arrow into an android figure, hold the power button, then press hold the volume up key. Timing (on my phone) is important, you need to be holding the power key first, then get the volume up key while the box and arrow are still there.
If you get to the Android and triangle, you might still be able to do the two buttons to get into recovery, but it doesn't work on my phone; some reports on various blogs say it does, though.
Once in Recovery, you should be able to pick the option to factory wipe/reset the phone. This will wipe the ROM space and reset the phone, but it won't touch the sdcard stuff. You'll have to set up the phone again, but that's not too difficult.
Just trying it now. Didnt realise about the 2nd stage of the power button and volume up. Just rebooting now after the reset.
Seems to have worked with the phone setup.
Will all my apps be gone?

Yes, all apps from the Market will be gone.
So will your wifi settings, user accounts, EVERYTHING, except the sdcard contents.
You're basically putting the non-sdcard part of the phone back into the same state it was in when you took the phone new out of the box.
I'd recommend appbrain.com for your phone to have an easy way to reinstall apps if something like this has to be done in the future.

Ah, so much the better! It should just sync up after logging in with his account.
I thought I had to acknowledge I want that feature when I first set up the phone.
Either way, Appbrain still a neat combo of website discovery and phone installation, I find it very useful.
Ive been using app brain and the apps are being re installd.
However some of them that are in my list on the webpage, are not showing up in the app on my device. Any ideas why?

No, not sure, but if they're on your webpage, just click onto their links for the full app description page, then and cancel install if it's there as an option, and then install again.
this happend to me with two phones
Last night after my phone froze after downloading a wallpaper, after an initial pull of the battery the phone booted but the screen was unresponsive to touch, after I tried a hard reboot, with no success, I took it to best buy today and got a replacement. (Phone 1)
I Did system updated asked by the OS after i turned the phone on. (Downloaded update via wifi, and no sym card was in the phone) After Boot it was unresponsive to touch just like the last one. (Phone 2)
I went to Best Buy again and got a 3rd Nexus S. Have not done the system update and the phone is working well....for now
Any thoughts??????

Issue with power button?

Okay so I just discovered an issue with my power button.
I tried to take a screenshot but it just won't work anymore. Volume down + power just locks the phone.
Holding down just the power button locks the phone too. I don't get the extended power menu (for reboot, silence/vibrate etc)
Any idea what could be wrong? All this just happened randomly.
I'm still on stock, unrooted, 4.3
I don't want to root/flash it, and I'd prefer not to do a factory reset (backing up and restoring data is annoying) unless there's no other option.
you could download a third party app. Did you press them both together and with equal force? Did you try to reboot it?

I can't reboot it (without a third party app) because I don't get the extended power menu.
I'm a little scared to try a third party app in case it switches off the phone but doesn't switch it on. Then, with my power button not working, I'll be stuck with a paperweight.
I tried pressing them with equal force.
Could be a software glitch? Sometime my volume buttons stops working. After reboot the issue goes away. I am using PA rom 4.3.
Are you rooted? Using custom rom or stock? If rooted, download quick boot (reboot) by sirius applications limited from playstore. It let's you reboot your phone without using power button.

FIXED :
I think it was a software issue.
I held down the power button for 25 seconds or so and that rebooted the phone and now everything's fine.
Thanks guys!
For my part, I don't know what starts the issue. But I can't get the extended power menu with plane mode, silence and co AND turn off the phone either.
I have to do a hard reboot as well and it works again after turning on the phone. But after a while, all starts again and the only one solution is hard reboot!
If you have the same issue as I do, it will happen again... Sorry !

Touchscreen just died

I was using my Nexus 7 (2013) this morning surfing some sites, when all of a sudden my touchscreen just up and died. No laggy response, no jittery response, just nothing. I can't even unlock it when I wake it up. I can't power it off (as far as I know), since after I hold the power button down, I can't select Power Off.
I'm rooted running a stock 4.3 as fas as I know. Any ideas of where to begin? Thanks in advance.

I had the same issue when I didnt use it for 4 days. Touch would respond and when the power off dialog came up I couldnt touch it but just hold the power button longer and it will reboot. I held it for about 15 seconds maybe 20 and it will restart
Well, if that previous posters suggestion does not work, or any software-related solution, my first suggestion would be to send it back for a replacement, barring that, it sounds like something could have come loose, if you're the type to try it, you can see how that is addressed with the 2012 version:
Google for "How to Fix Nexus 7 Touch Screen Problems", the video is by Tampatec.
Happened to me too once but i was on a custom rom and kernel. I freaked out when the touch wasn't responding!
I held down to power button to power-off/reboot. It seemed to result in a bootloop and i wasn't exactly patient because i was freaking out a bit!
So, i powered down the device again, booted into recovery (TWRP) and to my relief the touch worked!! I just rebooted back to the system and everything was fine.
This happened to me on stock android 4.3 twice. I believe it is a software issue with the last one or two factory builds of 4.3 for this device. As previously stated, my problem was fixed by holding down the power button for about twenty seconds until it rebooted.

I got it to reboot and that seemed to do the trick *crosses fingers*

Had this issue too a few days ago. I connected it to my PC and rebooted it via adb reboot command.
Occasionally I get this issue after switching the screen on running completely stock 4.3, but I can solve it by holding the power button - not to reboot, but just so the menu comes up. That alone wakes the touchscreen up for me.

No sound on lollipop?

Fixed problem by wiping cache from stock recovery
Anyone else flash factory image and now has no sound what soever? Completely clean factory image flash and no headphone or speaker sound. Only vibrations. Made sure everything was up all the way and tested on YouTube and play music and notification sounds. I saw one other person post they had the issue. So is it anyone who flashed factory image or everyone?

I have sound, but the button works backwards.
I was just coming in to ask the same question - no sound at all on my N10 on 5.0 factory image. Strange. Makes it really useful as an alarm clock, eh?
Fixed it. If you have the issue reboot into stock recovery and wipe cache. Works after that.
No sound on Nexus10 after upgrading to lollipop
I have the same problem as others with no sound from nexus 10 since installing lollipop.
I don't understand how you can do, what has been posted. Please can someone tell/explain how to do it.
PLEASE

I've tried following these instructions several times so far. Each time I get to the point where I'm pressing the power button to enter recovery, the screen goes blank for about a minute, and a "No command" message is displayed, along with a picture of a dead android robot on its back. The only thing I can do at that point is to hold down the power button until it reboots normally. I never see any option to wipe cache. Suggestions?

Mine did exactly same. Sounds worked after boot though..
My N10 with Android 5.0.1 will always cut off audio if I power it on with a headset plugged in. I just unplug the headset then reboot and wait until the desktop is displayed before using the headset. That's never failed yet.

When You see screen with android on his back (and triangle/exclamation mark), just one more step: hold Power button and tap Volume Up once before releasing the Power. A list of items should now appear at the screen. Now, you can wipe the cache partition (~10 minutes to complete).
Nexus 10 no sound

I need help. I wiped out the cache partition following the above instruction but unfortunately, still no sound. The only way I have sound is via my bluetooth speakers. Any idea what I can do next?
I ran into this problem a couple days ago when booting after a recharge, with 5.0.1. No sound coming out of my Nexus 10, no matter what I did. Simply rebooting the tablet fixed it.
Just restart phone
All I had to do was turn my phone off and on. Running Nexus 4 on Lollipop.
Cause of the Sound Issue...
This is what we know based on several trial and error tests. The issue occurs when you have the tablet plugged into a charger and unplug it. Not sure why the issue is caused this way but each time it happens that was the case.
Solution...
After charging your Nexus 10 you will have to reboot the device once to get the sound back. You could go in and clear cache although its generally easier for most people to just restart the device. Have noticed best results when the tablet is on then turned off and back on again as opposed to just turning it on from a dead state.
I know this is annoying and more of a temporary solution but it will get your sound back just the same until Google pushes out an update to fix the underlying issue. It is annoying having to reboot the device each time you put it on the charger but for the time being it works.
Hope this helps.

For me it also kills the front mic but the back one works. The solution of restarting fixes sound and mic for me.
So its not just me. Good.

Reboot With NO Attached Devices
Try rebooting your Nexus 10 with all connections to external devices detached and off. This means NO power supply, NO bluetooth, NO HDMI cable, NO headphones, etc.
You may need to do this a few times. This worked for me when no other remedy worked, and I tried everything.

Phone sometimes restarts into fastboot mode (and other weirdness)

I've been having a weird issue with this phone almost from the very beginning, in that the restart and shut down options in Android almost never work properly. I have seen the following take place:
When I select restart, the phone reboots into fastboot mode. Selecting the "start" option continuously reboots the phone into fastboot. I then have to hold the power button down for ~10 seconds to get it to boot normally.
When I select restart, the phone shuts down but appears to do so incorrectly, as I also have to hold the power button down for ~10 seconds to get it to start up again.
When I select shut down, the phone restarts.
This behavior happened on Nougat, so I tried sideloading the Oreo beta 3 to see if that would help. It didn't. I also did a factory reset after installing the Oreo beta, which didn't help either. I've done nothing to my phone (rooting, unlocking bootloader, etc.) besides sideloading the Oreo beta 3.
Essential support has offered to do a warranty replacement of the phone, but my problem is that I live outside the US and cannot easily send the phone back. Ideally I'd like to figure out the problem as I assume it's a software one, but am not sure what else to do. Essential support thought that the volume buttons could be defective, but in Android they function perfectly (i.e. if there was a problem with phantom presses on them I'd expect the volume to get randomly changed in Android).
The only other option I can see is flashing a full factory image, but since I just did a factory reset after installing Oreo I'd really rather not do this unless there's a high chance of it fixing the problem.
Any suggestions?

That's interesting. My Essential did the restart but shut down thing for the first time today. I'm not rooted and only running the current Oreo 8.0 beta. The only thing I noticed is an update yesterday from the google play store of Essential Services. I wonder if for me they are related.
It's possible but in all likelihood the problem was there before and it just never happened until now. Even on my phone, sometimes it does reboot properly and sometimes it doesn't. I haven't figured out any rhyme or reason as to why it happens. I bet this is a problem that many people haven't noticed because few of us regularly reboot or shut down our phones. For me this has been happening since Nougat, and the Oreo beta didn't change it in any way.
