Waiting time for screen on.

I have tried kj4, kka and sheep rom. All have the annoying long wait after pressing power button intil the screen is lit up. Also tried different CPU governors without result. What is the problem here? And can it be solved?
Is it just me, or do others experience this as a prob?

I've got the same rom, but I don't see the problem you described.... try to reinstall the rom.
ps: you should post this under the thread of your rom, without creating a new one

You may have a defective device.

mine is like 2seconds after the bootanimations and stops at samsung logo..fast enough for me

I have the same problem with my note. I just got mine yesterday. No clue as to what's causing it. I updated my firmware to the latest but left the old kernel so i could keep root access. Had the same problem with both the new and the old firmware.

Just to clarify the issue here:
When the phone is on but screen has been off for a while, the time between pushing pwr button and until the screen lights up is about 1 second, it may not sound much but it just enough to make one press the button once again. Not what i am used to on my previous androids from HTC.

Same here. KJ4, stock KKA and sheep KKA. It is annoying indeed...

Probably a user experience thing, you guys who claim to NOT have the issue:
Can you lock the screen and wait for like 10 mins and then on the screen again and time the delay from button press to screen light-up?

Where do you come frome? I mean are u used to Samsung devices or something else?
I am judging this by my 2 previous HTC's whith all kinds of different Roms where I have never seen this.
My thought is that it is on all notes but some people does not see it as a problem but you and me do.

I am having the same issue. Takes 1-2 seconds until the device is fully powered up from standby...

I think I figured out the issue. I disabled weather on the lock screen and now my phone comes straight on. Maybe everyone with the issue can try that and see if it works for them?

Confirmed, getting rid of the weather on the lock screen gets rid of the lag

I'm having the same prob. I'll try removing the weather app and see if that helps.
Great no I cant remember how to remove it. help

nope mine is snap on... did u try turning off display animations? if not try it

This was there even on the s2..

yea, mines also has the same 1-2 sec delay. no weather on lock screen. found it odd, cause i've only had HTC phones so far, and never saw this.

Samsung don't use early_resume in the kernel, that Seems To be more qualcomm Related code.
It's that Code that gives you instant screen resume on the HTC devices et al.
I found this a niggle on the note as well, but have got Used to it,especially compared to amount of work it would take to fix it.

From what I've seen, others with similar problems have returned their Nexus 7 to the store they got it from and exchanged it for a working N7. I would recommend you do the same. If you got yours from the Play store, start an RMA. If you got it from a B&M store, exchange it.
Since you've only had your N7 a week, you shouldn't have any problems exchanging it.

It seems like it's an issue with the touchscreen itself. I have no idea how to verify or solve this issue, though. That's why I would personally exchange the N7 as defective. I would think that since your problem is clearly demonstrable, it would be easy to exchange or RMA.
But there may be a solution around that someone else has heard of. If anyone with greater knowledge of touchscreen issues wants to weigh in on this, please do.

I just started seeing this issue. At first it was only happening within apps. I thought it was issue with maybe stretching the app to a larger screen. But I started seeing it on the home screen.

There was a fix posted here somewhere for a package called surfaceflinger-fix.zip you flash in recovery. Made a huge difference on the touchscreen non responsive issue.

and when you turn off display and turn on again problem will fix

I have also experienced this. I I didn't try turning screen off then on but I rebooted then it was fine again.
I'm more inclined to think that this is a driver bug than a hardware fault

Lockscreen freezes after sleep

Hello!
Just got my Nexus 4 and I am loving it. But my Lockscreen sometimes freezes when I hit the power on button, or it is at least unresponsive. I have to turn off the screen and turn it on again to unlock. This happens everytime the phone has been locked for a while.
Any fix for this issue or should I get my phone replaced? Seems software related

I have the same issue and wants to know the reason.

I have the same problem, and I think i have found a way to replicate the issue.
1. Turn off the screen.
2. Wait around 5 seconds.
3. Put three fingers on the screen at the same time.
4. And immediately without moving the fingers turn on the screen.
At this time the touchscreen doesn't respond or it has some kind of lag and you have to reunlock the screen to make it work again.
Can anyone test this?
Sorry for my english.

I can reproduce using this method. It's very annoying when it happens in the wild though, I was unable to unlock at all the other day, had to power off and on the device. Also wasn't able to answer a call !!!

i have the same issue too. I thought my unit was defective.

So is this a software or hardware issue?

Hi,
I seem to have the same issue. It renders my phone useless. While trying to figure out what exactly is affecting it. I found if i enable under developer option >> input >> show touches the next time this issue happens i can see that the phone screen is constantly being touched (w/o having any finger on screen).
I am also awaiting any solution for this issue.

Let's just hope that this can be corrected with software.

Weird graphics corruption.

Hi. I have had this Nexus 4 for about a month and it has does some strange things with the graphics on the bottom bar of buttons. Please see the screenshots attached. It can happen every few minutes and as soon as I touch the screen it will revert to normal again.
Is this something that is likely to get fixed with an update or a hardware issue?
I can't find anything on the internet referring to the same problem but the sales guy in the local carphone warehouse has a nexus 4 as well and said his does the same :-/
Anybody know what is causing it.
Completely stock BTW oh and as you can see. Pressing the hardware buttons for a screenshot does not fix it. Only touching the screen.
Sent from my Nexus 4 using xda app-developers app

Wow.. thats not normal! I would look into RMA'ing that sucker!

You could try using a toolkit to reflash stock to see if that helps, however you will have to unlock the bootloader, flash stock rom and then relock bootloader, then you just go into settings and do a full reset to hide the developer options then you will be stock. The toolkit I use is this one http://forum.xda-developers.com/showthread.php?t=2015469 and its awesome just follow the on screen prompts.

I'm quite sure that this is a software issue, since hardware issues can't be captured by screenshots obviously. I'd recommend flashing it with whatever you like and do a factory reset. You can restore all apps afterwards ofc (use Titanium Backup for example).
Best regards!

That only means that it isn't an issue with the physical screen. It could still be an issue with the GPU or other hardware, since various hardware is used to create that software image in the first place.
I have seen exactly this sort of picture posted in at least one thread before on here before, though that might be hard to find on a search.
I would also recommend reinstalling the ROM and if it still happens then it must be hardware. I strongly suspect that it is the hardware.

Thanks for all the replies
I have now disabled HW overlays and it does seem to have fixed the issue (or at least made it far better, I have not noticed it since but it has only been an hour)
I will keep in eye on it for a bit and if it lasts cone back and change the title of the thread to solved.
Thanks for all the help guys.

hmmm, and the gpu just decides to screw up down there in a perfectly aligned rectangular shape that happens to resemble the navigationbar? i think thats unlikely.
gimpor, can you play gpu accelerated games? try please.
its probably googles weird 4 layer stuff. thats why disabling hw overlays fixes it. same guy that screwed up the kernel colors that merged it into 4.2.2 btw. : P
gimpor again,
hwoverlay is not permanent, a reboot unchecks it. try this
replace persist.hwc.mdpcomp.enable=true
with debug.mdpcomp.maxlayer=3
in your build.prop
or in the worst case persist.hwc.mdpcomp.enable=false

Its much better but still not fixed. Only done it once in about 8 hours whilst playing a solitaire game. I will try the other suggestions when I have decoded them into English :-/
I have not found any games that don't work yet, bad piggies etc. Seem to work okay. Would they be GPU accelerated?
Once again thanks for the assistance with this, it does get rather annoying when you show someone your phone and it's all garbled.
It still does this though :-/

I haven't found out anything further and it's still doing it but not as bad. It doesn't seem to happen to every stock phone so I'm guessing its hardware related, or at least something in software not playing well with this specific hardware. Mine is a 212 so they may have changed something on the later ones. I got it from Carphone warehouse on the UK as they were the only ones with stock. I had it changed already as the first one I got was DOA. I think it's going to have to go back if I can't get it fixed soon.

Anyone else sometimes experience touches not registering on the touchscreen?

Randomly it seems, when I tap on the touchscreen on my new N7 2013, nothing happens, and I have to repeat the process several times before my touches are registered.
Does anyone else have this problem?

See my thread titled " Another touch issue, with reproducible steps".

Go into developer options and enable "Show touches" and "Pointer location"
If you see your touches registering but the app isn't responding, it is probably a problem with the app. If you see random stuff on the screen, probably a problem with the digitizer or digitizer in combination with the driver/software in this release.

Ive experienced this a few times and it seems to be a software /hardware interface issue with particular custom rom builds ive installed. I know the touchscreen hardware itself was fine when I forced reboot into recovery and the touchscreen worked as normal in custom recovery.

I wouldn't. If you had a Verizon Galaxy Nexus when it came out, you'll remember that it had the same issue with certain points on the screen (lower right hand corner) when using multi-touch applications. The entire screen would either stop seeing input or start going erratic and creating faulty inputs that weren't happening. It isn't a hardware issue, proven by some users experiencing it and some not. The only time I've experienced it is in the Netflix application while trying to choose a show to watch. I re-boot the application and viola, no more issue. Some in this thread even are stating that they only see the problem sometimes after getting the 4.3 update.
In short, it's software and not hardware.

Same issue when not touching with both hands somehow (like if the tablet is flat on a table).
