I've used the stock one, Franco, lean, and ak dummy. They all have the same problem. I feel like I shouldn't have to restart every day, should I?
[Samsung Galaxy Nexus] madphone:
try greenify to prevent unwanted apps running in the background. it really helps when it comes to multitasking and battery life: https://play.google.com/store/apps/...biflipde&utm_medium=website&utm_campaign=blog

what kernels do is mostly placebo i think. They are only good for added functionality like OTG or screen calibration, not for performance.
[Samsung Galaxy Nexus] Deejayadhd:
i had issues like that when i first flashed a 4.2 rom, tried a few and all were terrible and had reboots. finnally had the idea to wipe sd storage along with everything else and all 4.2 roms i have used since have been like butter. i always flash ak kernel.
[Samsung Galaxy Nexus] devarshi:
I just found greenify the other day. It seems to be helping, but I had a SOD this morning.

Why would sd storage make a difference? I'd hate to wipe it, but I'll try if I have to.
[Samsung Galaxy Nexus] Liskrig:
What is the CPU temperature when you notice the most lag? The nexus has thermal throttling to save our phones from melting in our hands. It could be the culprit... Or at least a part of it.
[Samsung Galaxy Nexus] grognaz:
so finally some other people get this problem... having this issie for quite some time now as soon as i use something else than pure stock.

after a reboot it runs really smooth but the cpu usage for everything is always extremly high on custom roms/kernels and locks up the device if some io operations happen.

on pure stock it never locked up.

since i have no knowledge about finding the culprint i can only hope that some dev will get that issue and travk it down.

it sucks to run stock....
[Samsung Galaxy Nexus] grognaz:
mmcqd appears pretty high on cpu list when it gets to the lockup... anyone has more infos on that one?
[Samsung Galaxy Nexus] LarsAussems:
Thanks for your answers, it could maybe be related to aokp itself. Aokp build 3 and a few nightly builds have a memory leak issue and bad ram behavior.

[Samsung Galaxy Nexus] sl4y3r88:
Ever since I changed from 4.1.1 yakyjxw to 4.2.2 Takju ive been having random lag which requires me to reboot to fix. So annoying..I Just want to have stock 4.2.2 and everything to run smooth like 4.1.1!!
[Samsung Galaxy Nexus] grognaz:
im on sourcery and also have the problem, was on cna and also had the problem and on aokp as well. actually it was the reason i left aokp but every rom is the same.

the only rom i never had it was pure stock. and as soon as i used a custom kernel the problem returned.
[Samsung Galaxy Nexus] grognaz:
and back to stock.... couldnt stand the bad performance i get from all the custom roms i tried:banghead:

i would like to get to the root of this lag problem because i hate stock lock but this lag is even worse than not having all the freedom:what:

Issues with some specific build

When I used Cyagenmod 10 - specific builds I faced this issue. Later they fixed it.

FYI. Currently I am using the PAC version 19.9.0 ( Android 4.2.1) for my LG Optimus one P500 phone. It is giving some great look and feel. Smooth operations. Still Battery draining and 'no FM radio' support is the major minus in this build.

[G Tablet Q&A, Help & Troubleshooting] a fraking toaster:
so my sister gave me a free g-tab and said if i can fix it i can have it( i guess it was her old bf's or something).anyway it wont turn on and will not respond to anything, although the charging light does turn on when the charger is plugged in.i have tried the reset button and the volume/power combo and nothing happens.i manage to get my pc to recognize the tablet by shorting out the k1 connectors next to the reset button but screen doesn't turn on.i also installed the drivers and attempted to nvflash but got stuck when it says waiting for bootloader to initialize.im not sure if the screen is supposed to be on at this point or not.
[G Tablet Q&A, Help & Troubleshooting] rajeevvp:
Does the screen brighten at all (it may still remain black) when the tablet is switched on? If it does not, then open the tablet up and check all the cables going into the LCD panel. Try unplugging and replugging all the cables at both ends. Make sure you ground yourself before doing this.
[G Tablet Q&A, Help & Troubleshooting] a fraking toaster:

[G Tablet Q&A, Help & Troubleshooting] a fraking toaster:
all cables seam to be inplace and no broken wires or anything that i can see..could it possibly be a dead screen?or maybe somthing with the apx boot were it doesnt turn on the screen or something along those lines.
[G Tablet Q&A, Help & Troubleshooting] rajeevvp:
A visual inspection might not be enough. Unplug and replug all the cables going into the LCD screen at both ends. Do this for all the other detachable cables too.

If it's not the cables, then possibly yes. If you can get into recovery (even blindly), then we might be able to make out something from the kernel messages.
[G Tablet Q&A, Help & Troubleshooting] a fraking toaster:
ok so took out the screen cable and seams to be in good condition.also kept it oiut for a min or 2.still no backlight or anything.how would i go abouts geting into recovery blindly?
[G Tablet Q&A, Help & Troubleshooting] rajeevvp:
Does the LCD screen display the backlight (pure white) if you disconnect the LCD data cable completely and then power the tablet on?

How many cables go into the LCD? 1 or 2?
[G Tablet Q&A, Help & Troubleshooting] a fraking toaster:
im not sure i just disconected the main cable with a bunch of wires coming out.i didnt see any other cables running into the lcd.i dont think the screen would be broken.from what i heard it worked find and then he had to push the reset button and then it worked fine for a while and died out again.so im hoping its a softwear issue and not the screen.
[G Tablet Q&A, Help & Troubleshooting] rajeevvp:
The way to determine this is to unplug the cables to the LCD screen and power the tablet on.

See this thread. The usual result of a disconnected LCD cable (it can be at either end) is a pure white screen. This implies that there must be 2 cables going into the LCD screen. One to power the LED backlighting, and another to carry the video data. If only the video data cable is disconnected, then what you will see is only the backlight--a pure white screen.

However, if there were only one cable (combined backlight power and video data) to the LCD panel, then a disconnection of that cable will cause the screen to go completely dead. It wouldn't result in only the backlight being on.

So, dismantle the tablet as much as you can and see how many cables go into the LCD panel. If there is a backlight power cable and it is disconnected/loose, then the screen will be dark even if the software is all working. Let's eliminate this possibility first.

It's getting late here, so I'll check this thread tomorrow.
[G Tablet Q&A, Help & Troubleshooting] a fraking toaster:
just checked.no other cables running to the lcd screen.thanks for the help.ill be here when u wake up ROFL
[G Tablet Q&A, Help & Troubleshooting] rajeevvp:
It might not be a "cable" as such. But, there must be something else to supply power for the backlight. See this post, this one, and this, where the user says that their (normally visible) cable to the LCD was disconnected. And, the disconnect resulted in a white backlit screen not a completely black screen like yours.

Does your screen show the backlit white screen if the tablet is powered on with the visible cable disconnected?
[G Tablet Q&A, Help & Troubleshooting] a fraking toaster:
no it doesnt turn on with the cable unplugged....i will take the whole thing apart make sure there isnt another cable running into the screen.

just checked.theres no other cables running to the lcd.the cable is secured tightly on both ends.
[G Tablet Q&A, Help & Troubleshooting] a fraking toaster:
upon further investigation into the lcd i manage to peel off the tape that was covering the lcd inverter....i had an experience once with my laptop when the screen was all black and did nothing but the system itself was fine.all i had to do was unplug the lcd inverter and plug it back in and it reset itself.im hoping this will work too,

update...unplugging the inverter and plugging it in did nothing.still a black screen.im thinking its a not the screen thats broken but something wrong with the software that is making it not turn on.
[G Tablet Q&A, Help & Troubleshooting] rajeevvp:
That doesn't make sense. That one visible cable cannot be supplying both power and video data to the LCD panel.
[G Tablet Q&A, Help & Troubleshooting] a fraking toaster:
there is 24 small wires within the cable....it includes the red and black power cables and verious other colored cables.
[G Tablet Q&A, Help & Troubleshooting] rajeevvp:
What's this LCD inverter? Can you post a pic?

Hmm. I don't know what to make of this. If that single visible cable is also supplying power, then how do you explain the fact that the backlight is on when this power cable is disconnected?

Still, use a continuity tester, or a multimeter, and check that all the individual wires are intact.

There are 3 independent software systems running on the gtablet: 1) the bootloader, 2) the recovery system, and 3) the ROM. Booting into any of these 3 will cause the display to brighten a bit--the backlight turning on. You mentioned that Windows detected the tablet in APX mode and prompted for drivers. This make me think that this is very probably a display HW issue. Plus, the fact that you see a black screen when others see a white screen when the visible cable going into the LCD is disconnected.
[G Tablet Q&A, Help & Troubleshooting] a fraking toaster:
i had an issue with nvflash were it would say its waiting for the bootloader to initialize and would not go any further.i dont know if that helps or not.maybe the bootloader itself is corrupt in such a way that it wont even turn the screen on?

and the issues that other people had with the white screen is that there cables may have been partially in the connection port and not all the way in securely.
[G Tablet Q&A, Help & Troubleshooting] rajeevvp:
Yeah, I have that in mind, and it is a possibility. But, I have to balance it against the fact that the bootloader managed to run far enough to initialize the USB HW. Otherwise your PC wouldn't have recognized the tablet. And the display HW is usually initialized before the USB HW by most firmware code.

But, let's check the HW first. If that's gone, then SW problems don't matter. Did you check the continuity on the wires?

BTW, is your usb cable OK. nvflash can fail to work if the cable is bad or the USB port is bad. Try using a different cable, and a different USB port on your PC. A screenshot of the nvflash command you ran will also help.

At least one person says that his cable was completely off.
[G Tablet Q&A, Help & Troubleshooting] a fraking toaster:
i just tried a diffrent usb port and got the same thing.i have abother cable but it is fairly dirty and rusted out so i dont think it will be better then the one i am using now.

here is a copy of what comes up when i run nvflash

[G Tablet Q&A, Help & Troubleshooting] rajeevvp:
Right. This is what I meant when I said that the SW was mostly OK (though it now does begin to look like there might be a SW problem too). If no firmware was running on the gTab, then you wouldn't get this far. If it got as far as this in APX mode, then the screen should've brightened a bit then gone dark. In actuality, you should've see the boot bitmap (the 3 VS birds) flash briefly, then the screen going dark. And, even if that bitmap got erased somehow, then the screen would've brightened a bit when a "blank" bitmap was displayed prior to entering APX mode.

As for the "waiting for bootloader to initialize" bit, which nvflash package (nvflash program and NAND partition images) are you using here?
[G Tablet Q&A, Help & Troubleshooting] a fraking toaster:
im not 100% sure what package im using.i followed the instructions from http://xdaforums.com/showthread.php?t=861950

i just did a continuity test on the wires and everything looks ok.im going to try a voltage test to see if the screen is getting any power when in apx mode.i am starting to think it is in fact a hw issue and not sw issue.i hope i dont have to buy a new screen,they are REALLY expencive.
[G Tablet Q&A, Help & Troubleshooting] rajeevvp:
Those files are OK.

You have a display problem for sure. Check the continuity on the wires and show the LCD panel to a HW guy.

EDIT: Post a pic of this "LCD inverter" you mentioned. And, feel free to update this thread anytime if you find out anything more about the LCD panel. Esp. how it's connected to the tablet motherboard. Based on the user comments in that other thread, I still feel that the LED backlighting on the LCD panel should have a separate power source.

As for me, I wish you luck; and I'm going to hit the sack now. Cheers!
[G Tablet Q&A, Help & Troubleshooting] a fraking toaster:
i wonder if it is the lcd backlight inverter.the continuity of the wires are ok.only thing i can think of that can cause it not to turn on is the backlight power inverter.i will do some tests on i and take a picture for you.i am also oing to see if anyone is selling a bricked gtab that i can use parts from.

AK Kernel 4.2.2

I've had a ton of success with AK kernels. Morfic and LeanKernel too, but lately the AK ones seem the best for me. I run a custom ROM tho, and I've seen that a lot of folks really like Morfic on stock 4.2.2.

If you're on VZW or Sprint, you may have to flash the GPU binaries to be able to install a true 4.2.2 kernel, otherwise you're phone wont boot and you'll have to reflash a 4.2.1 kernel to get back up and running.

Here is a mod that *should* disable wireless charging in the latest verizon update...

***I do not have a charger to test, but this is the same change I did in 1.15 for ViperDNA and it was successful...please make a backup before flashing! You may need to have services signature checking disabled to use this, ask your rom developer to do so***

changes systemui.apk

disables wireless charging popup/notification

works on stock deodex or odex

****this will overwrite any other mods you have installed for systemui***

Download

***Feel free to include this in your rom/project, just properly credit, thanks!

For 2.04 Verizon 2/15 OTA

For Developers Only!

how to apply this mod to your SystemUI project:

navigate to:

search for:

.method private final showWirelessChargingStatusForVzW

wholesale replace the method with this:

.method private final showWirelessChargingStatusForVzW(Landroid/content/Intent;)V
.locals 1

const/4 v0, 0x0

return v0
.end method

worked on 1.15 in viperDNA, no guarantees it works correctly in 2.04...some feedback would be helpful :angel:

(these seem like overly simplistic code changes in changing a 600 line method to the above, but should work fine...yes there are other ways to do it)
[HTC Droid DNA] MustafaHadaKing:

[HTC Droid DNA] nitsuj17:
tell me what the logcat says from the fc, because i pushed the systemui over viperDNA on 1.15 and it doesnt force close

its possible you may need signature checking disabled in services.jar (it is in viper)

I tried disabling signature checking in the services.jar but didn't seem to help. So that means one of two things 1.) I screwed up the services.jar 2.) thats not the problem. Thanks for your help. I'd be happy to post the modified services.jar if you think it would help.

any chance someone wants to look at my services.jar and see if I edited it correctly? If not I understand..
