Android is upgrading- trigger? - Nexus 5 Q&A, Help & Troubleshooting

So im using the nexus 5 for like a year and my power button became problematic, pressing itself sometimes, ordered a new button.
And im going to replace it, untill then, i downloaded third party apps to use the nexus without having to press the power button.
My question for you guys or experts, is what trigger makes my phone sometimes (after pressing the button which makes reboot) to go into the "android is upgrading optimising apps", and if it is a manual trigger with the power button, is it possible to turn it off?
Thanks in advance

[Q] how to track down the app that causes delays in turning the screen on

Hi, my S3 has a problem in that if the screen turns off and I immediately (well, fairly soon) press the home button or side power button to wake it up again.. there is a very long delay... so much that I only use the home button now, because I keep clicking the side button and often by the time the screen wakes up, it will have gone back to sleep because I had pressed the power button again.
So now I use home because home will not turn the screen off, only on.
Anyhow I'm sure it must be due to some app doing some processing when the screen goes off...
my question is, how do I track down the app? I have no idea which one it is
I have no problem to get the screen to turn on immediately, if some time has passed... let's say 30 seconds.. but often you need to turn the screen back on after it has timed out, so it's annoying to have to wait 10 seconds after immediately pressing the button.
btw. I use Cyanogenmod (android 4.3) but I don't think it's the cause because I don't remember this behaviour when I first installed it.
any ideas? thanks

I'm interested as well, I really wish samsung would improve the wake time on their phones. My HTC turned on without delay

[Q] button combination to force a shutdown

I must be searching for the wrong things. What is the button combination to force a shutdown on the Note Pro? Thanks.

Press and hold:
Power only - power off
Power + vol up - recovery
Power + vol dn - download mode.
Is this what you are needing?

Those were what I was expecting. But the power+vol combinations aren't doing anything on mine. It is a Verizon LTE version, but I wouldn't think that would make a difference?
They should work . . . best way IMO is to just do a shutdown from within the OS, then while the tablet's off press and hold a vol/home combo prior to pressing and holding the power button. Once the model number splash screen appears let go of power first while holding the other two . . hold the other two for a second or so and then let go.

Ok, this is really silly, but I don't find any way from the Note Pro's OS to do a power down, other than the popup from holding the power button?
(Sorry, bit of background, this all started from a problem that my power button was only working to wake the tablet, but after that, had no effect whatsoever. After mucho playing, for no apparent reason, finally the popup menu came up, I did a restart, and it's been 100% since than. But it has left me worried how to do a shutdown if the power button isn't working. No pulling the batteries on these things.)

Correct, when booted into android OS a momentary holding of the power button will bring up the power menu one option within which will be to power off. This is typical of many android devices.
Are you sure your power button is operating normally?
I have read elsewhere of a user having issue with his power button not feeling right (less travel than anticipated without much tactile feedback when depressed indicating possible defect).
I would like to add for clarity that there is no force shutdown via hardware button, only force reboot. Holding power down for several seconds will force a full reboot. Holding it down briefly to get the power menu gets the power off option in the menu to fully turn the tablet off. If your tablet reboots after this option is chosen then something is wrong.

No, because after returning to working fine yesterday it is acting up again. Not a hardware problem - if the tablet is off, the button will always work to wake it up. But once again, it is now not being responded to when the tablet is awake - either a quick push, a long push, or in combination with the other buttons.
It seems like this is a software problem, either driver or app, since mechanically the button works every time to wake up the tablet. And, of course, I can't do a shutdown or reboot to see if that clears it, because its not responding to the power button. Can't remap the power button because no root available on the Verizon LTE model. Frustrating.

I would take it back to Verizon. IMO software shouldn't interfere with a long depress forcing a reboot. That function is fundamental. This still sounds to me like a possible hardware issue where a long press is not identified as such (intermittent connection in the button).

But a short press also doesn't work when the tablet is on, but does work when the tablet is off. But then it clears up, and always works properly for awhile.
Unfortunately, unlike phones, taking out the battery isn't an alternative option...
I dunno what to tell you. Without root I don't see how any software you have installed on the tablet would have changed anything, and without the ability to get into download mode I'm not sure there's a way for you to do a factory reset that will fix the issue (if it is indeed a software one). I hope someone else chimes in that can help. My suggestion to take it in to Verizon still stands though.
Good luck!

DIsable reboot by power button 10 secs

Hi,
is it possible to disable the reboot when power button is pressed for 10 seconds?
i rebooted my phone twice accidentally when it was locked because the power button was pressed for 10 seconds in my trousers pocket...
thx for info...
As far as I'm aware that feature is hard coded into all android devices and can't be disabled. Its especially important for devices with non-removable removable batteries since if the device freezes you have no other way to force a reboot. I stand to be corrected though.
I'm assuming you don't keep other items in the same pocket as your phone? But perhaps you may want to look into a cover/case that makes it a little more difficult to press the button in your pocket.
This option plus "volume up + power button" is a one stop thief reset of the phone no matter what tracking app you have. Unless of course rooted. I would rather be able to disable this option as I have more chances having phone stolen than frozen.
On other Android devices I had, you needed to press at least two buttons at once for a reboot, so it would not happen accidentally. With Mate 8, I reboot it with the power button weekly...

Disable Power Button / Rom Suggestion ?

My primary phone has met its maker but my brother has given me an older/busted up Nexus 5 to use as a replacement.
The screen on the phone is broken up pretty good but I put a screen protector on it to stop from it shedding glass or getting any worse.
The biggest issue i'm having is with disabling the power button.
The button itself sticks frequently, and while I can find lots of solutions to waking the phone up, I can't find many solutions for disabling the power button.
The phone is currently unlocked and using TWRP. Just need to figure out how to disable the power button without bricking the phone.
In the same boat with a sticking power button.
I am using the "gravity screen" app to avoid having to use the power button.
I have been able to get through without using the power button for the last 6 months.
key things.
never let the phone power down.
restart the phone once every day . (use twrp restart or tasker for scheduled restart)
hope that helps.
Enjoy the Nexus 5
P.S. : I am close to the 3 year mark on my Nexus 5 after ordering it the day it was launched.

Stop phone from restarting when power button is accidentally pressed for 5 seconds?

I'm having a problem with the power button. It seems that it is a "feature" of the Honor 8 that if you hold down the power button for 5 seconds, the phone will restart without asking if that is really what you want to do. It happens either when I am carrying the phone in my left hand with my fingers wrapped around the buttons on the right side, or when the phone is in my pocket and I am working outside and I squat down and my pocket presses against the power button. Is there a way to disable the phone from restarting without asking? If the screen is unlocked, there is a prompt but after 5 seconds of holding the power button, it restarts anyway.
I think it's a common "safety" feature in practically any Android phone that if you keep power button pressed long enough, it will force reboot the phone. It's been that way in my Samsung, Motorola, Google, Asus, and Honor phones.
