Slow screen rotation..

Hey guys, on my nexus when im typing anything I turn it to landscape mode for the bigger keyboard and sometimes it takes ages for the screen to follow - sometimes it doesn't do it at all. Anyone else have this prob?

It is slow on purpose.

So that if you are in bed and turn sideways it doesn't just keep switching, and other similar situations.

No guys, I mean REALLY slow, as in 5-10 seconds. Sometimes I have to keep movin it around untill it turns. Today however its really playing up and not turning at all.. haha

I find that actually it's the exact opposite.
When I want it to rotate, I need to wait ages (sometimes tapping the screen while waiting makes it faster).
When I lie in bed, it very often rotates when I don't want it to, and then I wait ages for it to switch back to the previous mode.
That pretty much forces me to disable automatic rotation every time I am in the bed. Whatever they tried to achieve with this, either they failed completely or I am somehow mysteriously missing the point..

Mine has been staying, and being used to the HTC Desire spinning instantly it was a bit strange at first. As regards to the tapping, there are some modes where tapping is what rotates it and it wont until you do.

Same damn concern very annoying

I mean in applications like the stock Browser. I'm not 100% sure, but 99% that it rotates faster if I tap the screen as compared to just waiting.

it's not slow
it's the smooth transition animation (like windows IE)
you will need some 3rd party tweak to disable it

OP is talking about the screen taking awhile to finally rotate when he tilts the phone. He isn't talking about the phone not tilting at all.

Screen Flicker

Has anyone noticed their GN turn on by itself and turn off? I've notice this happening a few times a day and each time I think it's shutting itself off but its not. Nothing is running or the table wasn't nudged in any way. I can only catch a glimpes of the screen turning off before I notice it. There's also nothing moving or any light to reflect off the screen to make me think its a reflection...
Just wondering if anyone else notice this... I hope it's not all in my head.

Could be an app doing this, are you using: Delayed Lock, Unlock with WiFi, any lockscreen replacement app?

never thought about the delayed lock... That seems likes the easiest answer to this.
Thanks!

Yup, if you are using DelayedLock that is most definitely the problem, and one of the reasons I abandoned the app. That and it doesn't play nice with Juice Defender.

[Q] Does anyone else experience unlock screen lag on 4.04?

I updated my GN to 4.04 a few days ago(stock rom), but after the update I frequently experience lag when I swipe to unlock the phone. This issue does not happen every time, but definitely happen very often to me. Kind of annoying.
I tried to reset the phone, change the wallpaper from Live to static, also reflash it as well. But the issue exists anyway.
Is this a typical problem?

It happens to me also on stock 4.04.

I notice a little lag when using the pin lock screen as well, but not all the time.

Me too, I find that if i turn off 3g, the lag would be less. But I am not sure.

Try disabling auto brightness?

I notice it too. I think it has something to do with the screen gradually working it way up to full brightness now instead of just coming on at full brightness like it used to in 4.0.2.

I have the lag as well. I tried wiping everything but it's still there. Very annoying.

Lag for me too using the pattern unlock. I can finish drawing my pattern before the green lines even start connecting the dots. It still unlocks, but it's not smooth like it used to be.

No lag with normal unlock. With pattern I noticed a small lag (not picking up the first "circle" I hit) but it wasn't always there.

I find that this issue happens if I change the light circumstance from dark to light, but if I am in the room and the light circumstance is constant, this issue will not happen.

I also have experienced the lag. As some of you say it looks like it happens when the auto brightness kicks in during the unlock gesture.
I've opened an issue on the android forum if you want to star it and give it more evidence.

I have left my message there, this issue really bothers me.

No lag here. Not on 4.0.4, not on any version before. But then again, I don't use auto brightness since it's just too dark for my liking. Also the screen doesn't 'dim' when switching on when you set the brightness manually.
It's a bug for shure just saying if you want a workaround...

Lag
Experiencing allot of lag at unlock screen.

Lag is due to auto brightness. Turn that off and lag should be gone.

For those of us having issues with lockscreen lag:
From what I can tell, it has to do with "smart flex" that is in the newer kernals. Between that and the custom governors included in most roms, it is causing 4.0.4 to lag until the processor ramps up.
I was seeing lag in stock cyanogen kernel, franco's latest nightly, and the latest nightly lean kernel
The fix:
I disabled smarflex all together, and I have seen zero stutter since. (I am currently using franco, and his app allows you to do this pretty easily from one of the options)
Its too early to tell because it has only been a few hours, but I haven't noticed a hit on the battery.
Hope this helps...
Cheers

I have the same problem as well. How does one disable the smartflex?

Screen off and on without using power button !

hi all
first time poster long time reader
I am so tired of trying **** apps.
Could somebody please tell me what app works with the nexus four to allow me to touch the screen somehow to see a text message etc when it arrives??
for the first time ever I am missing the button in my iPhone that let's me hit it to see what is going on at a glance.
I just want a way to toggle the screen on without hitting the power button on the Nexus 4
Sent from my Nexus 4 using xda app-developers app

The only way to do this is to leave the screen on, which would drain the battery. There's probably an app that would turn the screen off (or dim it), but this would keep your phone awake and drain the battery.
Someone feel free to chime in and correct me if there is such an app.

For the Gnex there's an app called “PGM", I emailed the developer if he had intention to update the app so it works with the Nexus⁴, but sadly he doesn't have the phone yet.

There is an app for that called tap tap app uses proximity sensor to lock and unlock screen.
Not positive is works on 4.2 but worth a shot.

Just wait for PGM to be updated for Nexus 4 support, OP; I can vouch for its greatness. You can enable double tap or slide to unlock gesture to turn the screen on. Once you get used to this, you seriously forget you have a power button.

It appears to work, but needs some calibration. I'm only able to get it working 30% of the time (if even).

you may try Smart Screen On : https://play.google.com/store/apps/details?id=it.android.smartscreenonlite
works on my Galaxy Nexus running 4.2.1

I'm waiting on a kernel that has Sweep2Wake...that would be awesome with this phone.

Wow I cannot believe the responses I got...
Thanks everyone!
I settled on the Smart Screen On.
Works about 75% of the time...I can live with that till something better comes along.
I don't really understand why you cannot make text msgs received light the screen up like it does on an iphone. It was so convenient to just glance at the phone and see it was work texting yet again and mutter under my breath for them to piss off and then go back to playing Xbox without ever having to touch the phone.

Try Light flow for that... I think you can set a custom LED color and the screen to come on with certain notifications.

Yeah I've got Light Flow. You can set the LED colour and the screen to come on with some notifications. There is a 'lite' version which should cover the basics. But if you dont use the stock messenger or use things like Whatapp, you need the paid for version.
I use it and it has great customisation BUT at the moment I can't get it to work 100% of the time. So be warned!
It will be great though once they update it for 4.2.

For now I'm settling for half of the equation; screen off with a double tap. I'm using screen off and lock from Play.
I had PGM on my GN and it works very well, the developer is planning on getting an N4 the last I heard.

I'm currently looking into getting the phone to wake using the volume rocker -- I'm reading that it's inside android.policy.jar and removing two lines that ignore the volume rocker button presses.
Anyone want to give it a go? I'm going to look into it this weekend.

I emailed him too! That is one of the best app out there, in terms of the idea behind it. No real battery drain, but still be able to wake your device from sleep. I died a little after getting that email.
Kinda hope someone would do something like that for N4.
You can use Tasker+Secure Settings (pro version) to use the Google Now shortcut to unlock/lock the device, but there is no waking the device.

I too am waiting for pgm! That would be amazing

Screen flickering issue! (All Galaxy S4's)

If you lower the screen brightness all the way down and open the stock internet to Google, and tap the search bar to pop the keyboard up, you'll see a slight flicker. So far on every display s4 at the store has the same problem. Anyone have an idea if this is software or hardware related?

Huh, I dont have that problem on my phone. Just tested it.

Same here. Tested and experienced no flickering issue.

Are you talking about the smearing issue when the phone is dim all the way and you have white text on black background. Text turns hazy purple when u scroll. If so this is a known issue that's been reported here already.

I've noticed flickering on super white backgrounds. It's hard to see and it's got to be the right lighting and high brightness. IMO if you need to go through a process to see a slight flicker, blobs, etc., it's not really a concern. I'm assuming it's software related.. Same with the text blur.

Go in any app with the keyboard popped up and go into the Sun directly hitting the screen and you will see your screen flickering endlessly no matter what app your in
