Tablet keeps turning on after I turn it off? - Nexus 7 Q&A, Help & Troubleshooting

Every time I turn off my tablet, the next time I go to use it, it's already on.
Anyone have any suggestions? Is this something that other people are experiencing?
Thanks!

Never experienced that
I don't know, My first N7 is faulty but not that bad, maybe your tablet is reading your mind and it turns on when your thinking about using it?

How are you turning it off? Tapping the power button only turns off display.

It's clearly haunted.
Or an app is waking it up to sync / find location / steal and transmit your data.
Have you tried running Avast ? Locking all the running apps ?

Don't think an app can turn it on after its been shut down..

So how does the alarm clock work :laugh:
And he hasn't said he's shut it down, he said he's switched it off.

quite strange..
I don't believe apps can turn it on when it's off..so if you turn your N7 off, your alarm is disabled. at least, I'm pretty sure of that.
And, so you watch it turn off all the way? And later on it's on?
Is it plugged in to the charger?
Have you ever watched it for a little while [while you were doing something else, just glancing at it once in a while] to see if it just randomly turns on?

I'm pretty sure that I turn my N7 off at night and the alarm wakes me up in the morning.

really? but how does that work?
that means the clock app must be able to control the rtc hardware, and tell it to power up at a certain time... I didn't know they'd done that on the N7...

OK, what if you temporary disable the calendar alerts? does it still happen?

Calendar -> Settings -> General Settings -> uncheck Notifications
It's a shot in the dark but who knows..
Or I suppose if you like you could disable calendar sync in Accounts & Sync, and then erase Calendar's data.

Midnight Wake Up

Have anyone noticed that the phone wakes up at midnight?
The backlight goes on even if the phone was in stand by....?
What is a Vampire-Phone?

yes i have seen this on my phone. it would drain my battery when i wake up in the morning, (I didn't set the power settings to let it go to sleep).
I cannot say if it is fixed because right now I have the power settings to put it to sleep in 1 minute if nothing's happening, I have also hard resetted my phone since then. but I blieve it was some third party application I installed before.

Alarm won't automatically switch phone on when it's time?

Hi all,
Do you all have any app to recommend for this? I'm a bit dulled by this fact that the alarm won't switch the.phone on when it's off.
Sent from my GT-I9000 using XDA App
This is a feature that android does not support and I dont think any app could over ride it due to the way the operating system is built.I do miss this feature from my symbian phones
When the phone is off, Android is no longer running. The phone itself probably supports a wake from deep standby, but it would be Galaxy S specific, and not something supported by the Android SDK.
are there any other solutions to this? Well, if not, I guess I have to buy a digital alarm clock.
Is there any feature I could let my phone know I am going to sleep, pls don't alert me until the alarm wakes?

I would just turn of the notification sounds in the pulldown menu so that you are not disturbed in your sleep by emails. I have sync on (All google services), let wifi on and loose just 2% in a night on my battery power.
Do you have any task killers running?
If so make sure you exclude the 'Clock' App from the list otherwise the Alarm will not go off.
Basically you need the clock application running all the time to monitor not just the time but when the alarm is due to wake the phone from idle.

A500 keeps waking up and staying on until the battery dies

This started happening a couple of weeks ago. I was using Honey Villain 1.1 and the 3.4 Kernel. Pretty much every time I'd go to use my tablet after leaving it for a while it would be dead. I'd check battery history and it would should that it had woken up and the screen was on for hours right up until the battery died.
I tried full wipe with Taboonay, Thor's kernel, the latest HoneyVillain 1.2. Every time I think it has fixed it but after a day or so it happens again. I'm out of ideas. I barely installed any apps the latest full wipe and it still happened. Is it possible the hardware has gone bad and is causing this? Should I take it back? Is there a log I can look at to see what is causing it to wake up and not go back to sleep?
Thanks.
Are you linked to a Picassa account?

Nope. I only had a handful of apps installed.
Root Explorer
Set CPU
Titanium Backup
Google Reader
EzyPDF Reader
AdFree
That's about it
This was happening before I started using Set CPU so we can rule that out.

OP- if you're not, be sure to disable picassa in sync. That damn thing will mess with you unless you disable it.

How do you disable Picasa? I just found out its been running for a long time in the background on mine event though I was sure is disabled it.

Under settings/sync/ click on the google sync to see the services within that are set to sync. You can disable it separately there.
the indicator light in the power button sometimes keep on for a long time, sometimes go off very soon... do not know why
mine does this too, i noticed it only tries to eake up about once. when you push the sleep button watch it for amsecond, when it turns back on, push sleep again and it should be fine. at least in my case it does.

The problem is mine is usually in my bag when it wakes up. By the time I realise it has happened the battery is dead.

[Q] Can't get Daydream to work?

This has been driving me crazy and I must be doing SOMETHING wrong because I can't get it to work on my Nexus 4 either.
I select Daydream and have it set to either or when plugged in, but the Daydream scene will not start, no matter which one I select.
In fact, here's what happens. I plug my Nexus 4 or Nexus 7 in set the Daydream to Clock (or any other), and the screen will just stay on. It will refuse to sleep until I press the power button, but it will sleep (screen off) if I turn Daydream off.
So I assume something is blocking Daydream from working? They are both running stock 4.2.1, bootloader unlocked and rooted. The Nexus 7 just had a data reset done and I even had reloaded the official images just yesterday.
I've also changed the sleep time to something different (currently set at 2 minutes) and it still doesn't do it.
Anyone know what might be causing the problem? Does anyone else have this issue?
Yeah, I got this as well. Daydream never starts unless I start it. Never comes on when charging.
Check developer options if "Stay Awake" is enbaled there.
Just a wild guess....

He said it goes to sleep if DayDream is not active.
Good guess though

Well, was worth a shot.... :silly:
So safe to assume then that Google botched this? No one else can confirm that it works?
isent it supposed to stay awake so you can see the option you selected...?
daydream works perfect for me. I can only use it though while charging. I haven't figured out how to get it in a dock mode without a dock

Have you tried all the choices (clock, colors, etc)? When I first tried daydream, I had to cycle through them before one would work, once I got that one to work they all started to work.

I wouldn't know about that, because I was playing around with them a lot when I found this feature, but it works since I set one (I use slideshow or that other pictures one).
You need to wait a little (= screen timeout), and then it starts.
I am confirming it.
So weird. I plugged in my Nexus 4 into my PC..and boom. All of a sudden it starts working. Randomly. Same with Nexus 7. WTF. How weird...
I wonder if it had anything to do with the December bug...considering it's December 1st now..
Stay Awake
You have to make sure "Stay Awake" under 'USB Debugging' ins UNCHECKED (third one down)
When I press the power button to lock my Nexus 7 the daydream wont come on, only when it goes to sleep after inactivity. Total bs... is that normal?

Wear24 - Stay awake when charging not working

I would have asked Verizon, but I need a Verizon number to contact customer support.
I enabled the developer options on my smartwatch and toggled on the option to stay awake when charging, but the screen still turns off. It even turns off if ambient mode is enabled. I suspect it has something to do with dock mode overriding those settings. Is anyone else having this problem or found a solution?
Thanks!
Edit:
I found you can disable the charging app from settings. This prevents dock mode from starting, but doesn't keep the screen on. I found that enabling stay awake while charging in developer options keeps apps open but turns off the back-light. If you look very closely, you can see whatever is open faintly. Disabling it will go to ambient mode, but still switch off the screen.
I finally wrote a quick app to do what I want.

My screen still turns off with the app set to stay awake while charging. I have tried with the dev options enabled and disabled for stay awake while charging. Do I also need to enable debugging as well?

No. Mine works without debugging on or the stay awake while charging option. It also works fine with always on screen setting on or off. I'm assuming you are using the Wear24. If your watch was running Oreo it might be more aggressive about stopping the app, but I wrote a case for that.
Is the notification displaying? If you dismiss that Android Wear may stop the background process.
For me I'm unable to disable it it's on all the time while charging enabled or disabled

Looks like it is working correctly. I restarted the watch and it is now staying visible while on the charger. Thanks!!
