[Q] Screen Blip when Power Off - Nexus 7 (2013) Q&A

Yes, I'm a n00b. I did search to see if I could find this as well and did not.
So, here's the deal, when I press the power button to turn the screen on, it fades in nicely.
When I then press the power button to turn the screen off, the screen appears to compress very quickly down to a white line, then blink off. This also happens when the screen auto-off kicks in.
Here is video of what is happening:
Oh...I can't post a link, cuz I'm a n00b.

Anyone else noticing this or is this unique to my device and I should return it?

Its the CRT effect and we all have this, I know in some custom Roms you could enable and disable this but not sure in stock

Huh...I used to have an Asus Transformer TF300 and don't recall this.
Is this supposed to be a "feature?"

I mean all the new nexus 7's have this, its been around on various Roms for ages, I quite like it lol

[Q] Phone unlocking screen issues

About 33% of the time when I go unlock my phone, the screen simply does not turn on, but I can still press the trackpad and the capacitative buttons. I have to keep pressing the power button for it to eventually turn on (after having the screen brieftly flash for a bit every time I try)
I'm using Cyanogen 7 nightlies, and it has been happening for quite a while. I'm not sure if it's an issue with Cyanogen, or a g2 thing.
Anyone has experiences with this issue or something similar?
Are you overclocking? Screen wake issues have been well documented with 2.3 roms when you have the screen on/off animations turned on. So you have a choice, turn of screen on/off animations, or turn down your overclock.
I recommend having a search of the CM7 nightly thread and reading in to the issue a bit more.

Ah thanks, that worked!

Turned off screen animations.

[Q] Screen Doesn't Wake Up

I'm running CM 7 Stable. When I push my power button to illuminate the screen, it doesn't do anything. The bottom buttons light up and I have to swipe the unseen unlock slider to get the screen to come up. This also happens with incoming calls. Some what intermittent, but 80% of the time I have to swipe the invisible slider. Any suggestions?

[Q] Alternative to Power Button to turn screen on / off

It's been something that has bothered me ever since I bought my Galaxy Nexus. The existence of just one physical button to switch the screen on and off makes me question the lifetime of Power Button.
Does anyone know of any apps, mods, whatever for this? My first thought was to enable the Volume Keys to wake up the screen, I have also read about the proximity sensor but I don't think having the sensor active all the time is a good approach. Another way could be shaking the phone to turn it on.
Taken from a google search .... "There's an app called "No Lock" that will wake the Nexus One using the Volume rocker"
May work on the Galaxy Nexus too maybe but i dont know
Yea, I've seen that app too but it doens't do exactly what I want. Plus it disables entirely the lock screen which is certainly something I do not want. :\
look for smart screen on app, it enables you to turn your device on and off with the proximity sensor

Please read the OP next time :-/
Cm9 has volume rocker wake. It also has a notification toggle that turns off the screen.

Screen off & Lock works fine & cuts the wear & t4ear on the power button in half. I halve it set up as swipe action in Nova launcher.
AOKP had volume rocker wake in the ROM Control too.
Can try this app "Smart screen on"
it uses the proximity sensor to wake the phone..

He said he doesn't want to keep the proximity sensor on.
Have you tried "ShakeOff"? Turn the screen off/on with a shake. I haven't tested it on the GN but it used to work on my old phone.

Volume rocker. You have warranty anyway for a year.
Also, you do realize there's only one way to accelerate in a car right? Are you worried that the pedal won't work everyday so you'll need to find an alternative way to drive?

that's a nice analogy. now consider this:
car's are made to last, let's say, for 10 years.
smartphones and electronics/gadgets in general aren't.
not even going to mention the "years of expertise" behind the mechanics on a car.
thanks - everyone - for the replies I will try those!
I will say the power button on this phone is we made and I'm sure it will last just fine
I've had worse. Like my thunderbolt

AOKP can do what you request.
my power button on my GN stopped functioning after 6 months of use. It requires me to press in very hard to get a response now or none at all. I'm in the process of backing everything up and beginning the warranty process with expansys. Have to say, I considered this to be the best phone I've ever had and this just leaves a bad taste in my mouth.
You could always try PGM Nexus (free). It allows you to unlock your phone by sliding your finger across the screen.

how so? I'm not one to nitpick small flaws, every phone has them. the power button failing is a major issue though. I would've still attributed it to a defective exception if I hadn't see many more people reporting the same thing. I did start using the volume rocker wake in cm9, but probably a bit too late

I have used this for a couple months and it works really great!
Even i worry a lot about the power button thingy. I use PGM nexus free version and it partially does the job. But for screen off i still have to use the power button.
Had a very bad experience with my moto milestone regarding the power button.

Pattern lock screen sometimes not centered?

Sometimes when I use the power button to unlock the screen saver, the pattern lock screen is off center. It's so far off center I can't enter the pattern to unlock the phone. I have to press the power button twice to get a new pattern lock screen that is centered.
I was wondering if anyone else has noticed this with their phone. I've got Executive Assistant running under the lock screen.
happened to me a couple of time so I stopped using pattern unlock screen. Once it got to the point where it stuck there permanently until I rebooted the phone
Happened to me a lot after removing the phone from car dock mode. Usually had to reboot, hasn't happened at all since switching to CM10 nightlies.
happens to my wife and me many times. we just do what you said.
Im guessing its a known issue because it happens to me and a lot of people I know.

Samev here happpen to me last night ivhad a call when I hung up the lock patttern went all the way to the right top side all ibdid was press power button
And thatsb it wnet back

Happens to me too. The fix is simple though:
1) Press the Emergency Call button. It should still be in place
2) When you see the number pad, turn the phone to horizontal view so that the number pad moves.
3) Press "back", the lock pattern will be horizontal for a second and then it'll flip back to its correct place!
I also had this happen many times. I turned off the lock function.
Is this on stock?

Locking device.

Hi there, i want to know if more ppl have this problem. Sometimes when i press the power button the device does not go into locking state, screen turns off but the screen off sound is missing. Also when i press power/home to wake the device it does not display the lockscreen. I thought i had a bad product so i swapped it with warranty and now my 2nd device also has this problem. I think its a fail in the exynos..... switching kernels didnt work either.

The only time I've ever had this issue is if I install the 23 toggles mod and try toggling the lock screen from there. It's never happened on the stock rom.
