LG G2 Screen Jitters after 4.4.2 update.

Nope not any better, infact it's worse. When it sits screen is ok when you wake it, but after about 5 min it starts jittering randomly. The longer screen is on the worse it gets until it shows sections of video that looks like old analog tv static. Turn screen off for a while and it's cleared up again for a few minutes.

Maybe something is overheating? Do you have a case on your phone? Mine has OtterBox case.

I even tried "playing" with thermal setting in 3845#*803# but did't solve anything :silly:

Don't know, maybe it's time to bring it in...
[G2 Q&A, Help & Troubleshooting] edgarpoe:
Ok I think it got scared that I was sending back for warranty because now it's running fine.
[G2 Q&A, Help & Troubleshooting] edgarpoe:
I've factory wiped phone 3 times, still had problem. Was almost wondering if after the update, the battery stats were out, if low voltage would cause it. But then phone would have died out of nowhere so don't think that's it. Last night I also recalibrated motion sensor but still had jitters.

Must have been just a glitch in the update.

Bell tech told me 4.4.3 is on its way anyways.

It was acting up this morning at 10, then it sat sleeping unplugged for a few hours (screen off) now it seems problem disappeared.
[G2 Q&A, Help & Troubleshooting] benz23:
Yep, i know the 4.4.3 its on the way, did the Bell Thec tell you when? it'll be frustating to wait around 3 weeks or a month with the phone condition like this... :(

BTW, Is your phone still OK? Ive been running mine this morning and got 2-3 hour up until now, jitter free... i will update if the jitters come back...

added :

Or maybe on of the apps is not compatible with the 4.4.2 Update. This morning this are my apps that have an update and maybe it solved the problem

- Chrome

- Air Asia

- Cleanmaster

- FanChants

- Flipboard

- Gmail

- Google+

- IGN

- Intsagram

Maybe some apps matchs with your apps?
[G2 Q&A, Help & Troubleshooting] edgarpoe:
My phone been steady now for around 6hrs I think. Not sure why yet. Wasn't app related that I know of because one off the reset trials I opted to not install any apps at all and still had jitters.

I've been working the modes, touch screen, and playback pretty good tonight and no more glitches. Was last plugged in 7 hrs ago to 100% and it's now at about 50%

Just noticed power save was off so now it's active.

With system, lg bloatware, and downloaded apps they total 197apps.

Tech didn't give any exact eta on 4.4.3, only said it was on it's way.

Just a quick Google search states the rumored release of 4.4.3 ours now pushed till next month instead of next week.

As of now, my D803 is still running jitter free since yesterday afternoon with 4.4.2.

Seems problem might have fixed itself.

:highfive:

Anyone else?

update:

ARG! Seems i spoke too soon. Video jitter just came back.

:p
[G2 Q&A, Help & Troubleshooting] benz23:
Me too, celebrate to soon… after aprox 8 hour no Jitter… then suddenly it came back… just as bad as yesterday :(

Its seems only the two of us having this problem :(

HELP!
[G2 Q&A, Help & Troubleshooting] edgarpoe:
Crazy... today wasn't too bad for mine, only a few recurrences.

Is yours a D803 (Bell Canada) as well?
[G2 Q&A, Help & Troubleshooting] benz23:
Nope, im using unlocked phone, not bound to any provider.

I have some question, when you say you wipe your phone, is your phone OS go back to the 4.3 (Jelly Bean)? or maintain the latest KitKat?
[G2 Q&A, Help & Troubleshooting] edgarpoe:
When you factory reset your phone it retains it's system partition, so Kit Kat stays. What it does is wipe it's data and cache partitions where all your apps, app data, and personal files are stored.

I tried a battery cycle last night. Let it drain dead, then plug it in until it's 100%. Not recommended to do that a lot because life of Li-ion batteries are rated for so many full charge cycles, but it helps reprogram battery's charge circuit.

(Lots of battery info can be found elsewhere in forum and by Google searching)

---------- Post added at 09:27 AM ---------- Previous post was at 09:23 AM ----------

Rare times when you upgrade, battery charge data gets messed up and doesn't charge properly causing instabilities and shorter battery life.

---------- Post added at 09:40 AM ---------- Previous post was at 09:27 AM ----------

Yesterday my battery stats where around 4100mV. Today at 100% after power cycling stats reading 3761mV.

No jitter noticed yet.

---------- Post added at 09:51 AM ---------- Previous post was at 09:40 AM ----------

I'm pretty sure our Battery is only 3.8v, so the way I see it my battery was getting overcharged.

We'll see how it runs today and I'll report back later tonight but so far no more video glitches noticed.

[G2 Q&A, Help & Troubleshooting] edgarpoe:
Well it's been a few days after power cycling my battery and it hasn't jittered at all since. Did it work for you?
[G2 Q&A, Help & Troubleshooting] s1mpd1ddy:
My rooted ATT G2 just started going through these weird jitters today. Knock on doesnt work and when the homescreen is on, ghost touches EVERYWHERE.

What's weirder is that the ghost touches show up in recovery too.
[G2 Q&A, Help & Troubleshooting] edgarpoe:
That sounds more like a hardware issue to me since you see it in recovery as well. Did your phone get dropped or wet lately?

Go into Developer menu and turn on show touches.

If you're running custom Rom is anyone else with the same kernel having the same issues? I remember seeing somewhere about knock code problems but can't remember where.
[G2 Q&A, Help & Troubleshooting] benz23:
After maybe 3 days almost Jitter Free (only a little shake, but if i just dont do anything for a while the screen stabilize), suddenly my phone start Jittering again today, im really confused. is it possible to be a virus? which activated with a specific trigger?
[G2 Q&A, Help & Troubleshooting] edgarpoe:
My phone been running great ever since a few full power cycles. Run it until battery totally does, wait until it's cooled down then let it charge back up with power off until 100%

---------- Post added at 10:06 PM ---------- Previous post was at 10:02 PM ----------

When mine had the video jitter, even factory wiping the phone didn't solve the problem.

---------- Post added at 10:16 PM ---------- Previous post was at 10:06 PM ----------

But then I noticed my battery had over-voltage (4.1v) even at 75% charge so that's when I tried a power cycle. (Even had overheat warning pop up and system shut down)

First battery cycle, phone had slight jitters only a few times. Cycled again and had been great since and battery charges to 3.7v at 100% now (and runs longer and cooler).
[G2 Q&A, Help & Troubleshooting] benz23:
Hmmm, OK I will try the fill charging cycle tonight... despite of that for my case, i found something pretty interesting... i realized 4 days ago, my packet data is expired so I used WiFi as my internet activity, but yesterday i top up my packet data and start to using 3G again... and the Jitter start.

Right now im turn off my mobile data access for almost 5 hours and my phone stabilize since (i cant say no jitter, but almost 90% of the time OK, compared to yesterday lamost 80% of the time Jittering)!! I need to confirm this further... while trying ur full cycle charger tonight.

Wish me luck :fingers-crossed:

Add : This morning i turn my phone on after full cycle charge, my phone is still jittering... I think its time to take it to the service center
[G2 Q&A, Help & Troubleshooting] benz23:
Im taking it in on LG Service Center, the tech guy said its Hardware problem, about some sockets loose or something like that, He fix it for 1 hour and complete, and because im still have the warranty, so its free, no idea how much if the warranty is expired. And i still retain the KitKat OS (4.4.2). but my data is wiped out.

So far 3 hours no jitters... and restoring the data right now. I let you guys know if the jitters comeback.
[G2 Q&A, Help & Troubleshooting] edgarpoe:
Hope that did the trick for you
[G2 Q&A, Help & Troubleshooting] edgarpoe:
ARG! As luck would have it I left my phone in the hot car today and just a moment ago when I woke it up my screen had some jitters.... Maybe it is hardware related caused by overheating. It seems to be ok now that it's out of the heat.... CRAP, I'll probably have to send mine in as well.

---------- Post added at 02:44 PM ---------- Previous post was at 02:39 PM ----------

Battery is reading 4.157v! Ack! That can't be good. 96% bat
[G2 Q&A, Help & Troubleshooting] edgarpoe:
I looked around online and a few places said the G2 battery is supposed to be 3.8v but now mine is charging to 4.3v, can anyone confirm what the voltage is supposed to be?
[G2 Q&A, Help & Troubleshooting] spamcakes:
4.3V is on the high end of the Li-ion chemistry in our phones.

3.8 is the "average" voltage the battery puts out, it is not a constant usually. When a Li-ion battery is fully charged it should never be charged over 4.3V, most people only let it charge to 4.2 for safety, likewise they should never drop below 3.4/3.5V or damage will probably occur.

The phone's internal circuitry takes care of the voltage difference by pulling less amps when fully charged and increasing the amp pull when going under 3.8V to make up for the low voltage.

Source: A lot of experience with Vaping gear that uses similar Li-ion batteries.
[G2 Q&A, Help & Troubleshooting] edgarpoe:
Oh ok, and here I thought the battery was being overcharged and causing video to jitter and scramble around...

---------- Post added at 10:40 AM ---------- Previous post was at 10:36 AM ----------

How's your phone now benz23? Did they say if it was from overheating? Mine seems to be ok now but had a few jumps yesterday after being in the hot car.
[G2 Q&A, Help & Troubleshooting] Sfkn2:
How was the turnaround time? I just sent mine in and am curious.

Sent from my Nexus 4, while driving in my Evo9.
[G2 Q&A, Help & Troubleshooting] edgarpoe:
Contacted bell for a phone service swap. Getting a free loaner sent to me and sending mine out for repair.
[G2 Q&A, Help & Troubleshooting] edgarpoe:
Photos of problems, and more problems....

Attached are screen shot photos of problems.

So I sent mine to Service, came back untouched. Apparently they didn't find anything wrong with it, even though it was acting up as soon as i started it.

I emailed them photos of the problem and they said to send it back and it would be taken care of by a supervisor.

Sent phone back again, and they sent me back a phone with a different IMEI number. I though cool, a new one.....

An hour later, the phone died so i thought maybe I didn't notice the battery had been low?

After plugging it in, instead of getting a momentary "battery charging" screen it showed up a message saying phone was disabled due to it being either too hot or too cold and battery is actually at 75%. Phone tries to turn on but dies shortly after the LG start-up logo.

Even after sitting for a few hours, same results.

Now quite livid over the matter, we contacted Bell about problems and "discussed our feelings" about the issues with our LG G2, including the overpaying of or new plan for less service compared to our old plan. (but i'm sure that's a different subject in the forum somewhere)

They said they would contact the repair depot and we received a refund for this month for the price difference between our old 3 year contract monthly bill compared to our new monthly bill on the two year contract started when we activated the LG G2.

Also they had "loyalty dept" reactivate our old 12Gig data share plan that i had with the 3 year contract, and lowering our monthly bill by $30.

So now we're waiting on a reply about the phone.

LG Customer Support mentioned to us back when the first issues started that if after repairing the phone three times still doesn't solve anything they would then send us a brand new device.

So that's where we sit for now, waiting on the verdict... :mad:

[G2 Q&A, Help & Troubleshooting] deanmalakian:
Fixed it...

Guys... I might have the solution as it worked on my D802 from Malaysia..

I've been facing the same jittering/flickering screen issue for the pass two weeks... I did send it for warranty but turns out to be my screen warranty has expired..

Even the technician said it might be the screen faulty.. But i did not trust him, since i have read few other guys in xda facing the same issue again after changed the screen or filter..

Atleast I saved few hundreds from my pocket..

My Solution:

1. Remove Weather Widget from your Home screen/Lock screen and force stop running Weather services in App Manager.

2. Install an App called "Greenify".

3. Add all pre-installed Apps by LG from your phone to be greenified.

Add into Greenify:

-Quick Translator

-Safety Care

-SmartWorld

-Video Guide

-World Clock Widget

-Dictionary

-Installed Themes.

4. Start hibernating those apps in Greenify.

After a while, my screen just stopped flickering.... Yeayyyy...!!!

Hopefully this solution will work with your phone as well... Finger crossed..

If you guys having problem going through these steps from your phone, try to cast the screen to your TV or use OSP on your PC...

Remove weather widget

Have you all noticed its been caused due to weather widget. After trying lots of things and reading bunch of posts online I read somewhere to disable weather app and tried it, to my surprise the flickering stopped.

So, all the people try out this: remove the weather widget, switch off your phone and restart it after couple of hours. Hope your problem would have been solved like mine.
[G2 Q&A, Help & Troubleshooting] Edward M:
Had the same problem, this fixed mine.

Go to settings >> More Tab >> About device.

Find "Build number" and click 6 times fast on it.

You will then get the message saying: "You are now a developer"

Come back to Home Screen, and then go back to Settings >> More Tab >> Now you will see the "Developer Options"

Now go to Developer options >> Drawing Section or Rendering Section >> Find "Turn off hardware overlays" or "disable hardware overlays" >> This will force the phone to always use GPU for screen compositing

Also turn off 'window animation scale' ' transition animation scale' 'animator duration scale'

Clear as many apps from start up screen as you can, including weather

[G2 Q&A, Help & Troubleshooting] MarshisnotMellow:
OP, this screen jitters, flickering, whitelines etc are common issue in G2 models.

this is caused due to a hardware issue, your software is working fine.

you need to replace the "EMI Filter" of your G2 with a new one.

with some times of use this gets loose or malfunctions, due to which screen starts jittering/flickering. but your display is intact, no need to spend money on getting display replaced, or digitizer replaced or software tweaks etc. just get your EMI filter changed and your display will work fine.
[G2 Q&A, Help & Troubleshooting] OT-Xtreme:
hey, from where to buy them? can't find anywhere please help (also where those are placed in the motherboard exactly?)

if someone could please write a good guide it wil be amazing cause to take it to a lab will cost way to much
[G2 Q&A, Help & Troubleshooting] MarshisnotMellow:
Its located near the charging port, you can access it by removing the lower back panel of your G2.

but keep in mind that its very delicate process, if you aren't well versed in repairing than its better to give it to LG repair centre and tell them exactly what you want to get replaced in your phone. Or you can go to any other trusted technician that will do what you say. Otherwise if you give it to any random technician, they will produce 100 more issues in your hardware except the one that you have and your phone wont fix.

ill give you a link for a post where its written what to sold on the LCD lines. but dont do it if you dont know what you are doing yourself. the connections are really small, so you can actually ruin the the connection eventually leading to no display.

http ://forum.gsmhosting.com/vbb/f494/lg-g2-d802-flicker-solution-need-help-1905072/index2.html

just remove the gap after http of link.

also there are video links / google links for how to do it, you just need to find it, like diamond in coal. (search for " emi filter lg g2"

this is what it looks like after fix : refer to attached image, that long processor you see, the last few connection on both sides, those have to be fixed.

[Sony Xperia L] Olivier:
If it's true that you used the PAC boot.img, then you made a huge mistake: It uses a slightly different ramdisk (e.g. the BOOTCLASSPATH is different) which will prevent most of the other ROMs from booting. If you really want to ZIP-port this ROM, use a boot.img from Vanir or CM (don't know about other ramdisks) and make sure you port from a similar device (display resolution etc must be the same).

Hint: You could just compile this from source.
