Phone screen randomly turns on after charging - Nexus 4 Q&A, Help & Troubleshooting

Before I go to sleep, I plug my phone into my charger and hit the sack. After ~1-2 minutes without touching it, my phone's screen lights up mysteriously. It does not unlock or do anything special, the screen just turns on. Not a problem right? Just wait ten 10 seconds and the screen will turn back off? NOPE. That sumofabitch stays on forever and the screen does not go back off until I click the side button to do so.
How can I correct this?

Seems to be a little delay between you plugging your charger in and the phone lighting up to show you have put it on charge. As for the screen not going off. Check your sleep setting it maybe a few minutes.

I could not find the sleep setting?
Are there any other suggestions or inputs?

You have to turn on the Developer options to disable this feature.
To do this:
1. Go to settings -> About Phone
2. Scroll down to the bottom where you see "Build Number"
3. Tap the Build Number button 7 times.
This will activate Developer options in your settings. There is an option in there to disable the screen staying on while charging.

That box is unchecked.
I think another issue that correlates with this is when I unplug my phone. When I remove it from the charger in the morning, my phone will still say "Charging" for an hour or so after I unplugged it and used it.

Are you using stock rom and kernel?

Happens to me when I use a regular car charger, which I think it may be defective (the connector part)

Yeah from the sound of it your connector is loose, so randomly your phone will think it has been disconnected and reconnected to the charger. Changing your USB cable should fix it.

Also try changing daydream settings? If you go into display settings, there is a sleep setting.. What is that set to?

Backlight

Does anyone know if there is a way to make the backlight stay on while charging. And also keep the phone from locking while charging. I think keeping it from locking would allow the alarm clock to actually wake me up, it shuts off when the screen turns off which is quick when its locked
Under power settings > advanced > uncheck both boxes under "On External Power"

The alarm should work when the phone is locked, I use mine this way all week for work just fine.
Ok thanks got the backlight to stay on. But when the alarm is set it only goes off for about five seconds and the sound shuts off and then displays a message

The Snooze/Dismiss message? What do you have set as the alarm? Is it a short tone or something a little longer?
Here's a good tip for using your phone as an alarm clock.
Set your alarm normally.
Go into power mode and uncheck the box to turn off the device after X time when plugged in.
Leave the turn off backlight box checked and set for 2 minutes when plugged in.
Now once you turn the screen on and the phone is plugged in, after 2 minutes the screen will dim way down and stay on all night making it a great alarm clock. I used an automotive cell phone holder to make the perfect cradle for holding it upright and at a perfect viewing angle. After owning a BB Storm, I just couldn't NOT have this capability... you get spoiled.
This works great.

[Q] Wake on screen touch?

Hi Everyone
I am currently in the process of putting a Nexus 7 into my car dash as a headunit/stereo replacement... however, once its in, the buttons will not be accessible... Which leave me with the obvious problem, when the tab goes to sleep... how do I wake it back up? Are there any settings/apps that will allow me to wake the device just by touching the screen?
Any help would be greatly appreciated
You can use a magnetic on correct spot of the screen to wake/sleep.
I stills dont own a N7 so cant tells exactly the spot on screen OR any other way to acomplish that

I have the same problem. The way I currently deal with it is I've set the Nexus 7 screen to stay on when charging, and then to turn off after 15 seconds once it is no longer charging. So turning the car on wakes it up, and turning the car off puts it to sleep after 15 seconds.
The "keep screen on while charging" option is under the Developer menu.

[Q] Screen turns on when battery is fully charged

Hi everyone,
i had the same problem with my S2, but is there any way to keep the screen from turning on when the battery is fully charged? I understand it's a "feature" to make me unplug the charger, but it's really annoying when the screen turns on in the middle of the night. So far i've been placing the phone face down, so it won't wake me up, but that's not really the solution i'm looking for.

It does turn back off in a few seconds (after the screen times out), right?
Honestly not sure how this little light can wake you up
In any case, did you try some of the apps for the older galaxies, like Battery Silencer?
Another suggestion would be to turn on for the night the Blocking Mode in settings , and configure it to suppress notifications.

In developer options you need to turn off "always awake" or the phone "wakes up" when it has charged.
If you can't see developer options in settings / other, tap build number 7 times and it will appear
Thanks for the quick replies.

My sleep isn't very deep unfortunately... Yeah it dows turn back off after a few seconds, but it still wakes me up.
As far as I understood, those silencer apps and the blocking mode only supress the sound of the notification or do they also keep the screen from turning on?

The "always awake" option is already unticked, but the screen still keeps turning on for the timout period

I have that turned off on my phone, and it still wakes up for a few seconds when it's fully charged. Wakes up when I plug in the charger, too. Neither one is a big deal to me, though.

Ahhh .... must be a "design feature" then
I leave my phone in the computer room overnight (don't use it as an alarm) so I've not noticed.

[Q] Stop screen from turning on too often (connect/disconnect charger, headset, etc)

I'm getting fed up of the screen turning itself on for things it really doesn't need to - for example:
connecting the charger cable
disconnecting the charger cable
getting to 100 % charged status
connect headphone cable
If I do want the screen back on at those times, I could just press the Home button. Any suggestions on how to stop this annoying functionality as I can't find an option for it?
Andre
I would like to know this as well. As would everyone else who charges it at night, I imagine. (Preferably without the need to root.. But I doubt that's possible.)
Would like to add "When answering call over headset" to that. It keeps muting itself in my pocket because of that every. single. bloody. time!
I normally have the "don't turn screen off while charging" mode enabled, so I can see it when it's on my desktop stand, and just manually turn the screen off with the power button once I don't need it. But the bleeping thing turns itself back on when charge is at 100%, and so it then stays on unless I'm there to turn it off. So I've have had to disable that mode.
There's a perfectly good LED to show me the charging status, why do I need the whole screen to wake too?
Andre
Any ROMs or kernels out there that anyone could suggest which support disabling the annoying screen-wakes on 100% charge, connect-to-charger, disconnect-from-charger, headset insert, etc.?
Andre
For anyone else looking for the same answer, try Wanam's Xposed module (http://forum.xda-developers.com/xposed/modules/app-wanam-xposed-customize-stock-t2383484) which allows you to disable a number of the more pointless screen-wakes (including 100% charge, and unplugging charger). Hopefully he can fix the remaining ones at some point too.
Requires root of course.

Screen always on

Why is the screen always on ?
The sleep setting of 30 seconds does not seem to work.
I'm on latest FW
My phone started doing this a few days ago. I did a test last night:
I plugged the phone in to charge,
I pushed the power button to turn off the screen and observed it was off.
I got up this morning to a 100% charge with the display on!
Hmm
Mine used to do this as well. I find that if the Ambient Display option > lift to check phone option is active will cause the phone to wake sporadically with little vibrations. I've turned this option off and just have notification wake my screen.
