[Q] Help Freaking Out

Have a major problem with my screen when turning phone on or rebooting the screen looks fine. But when I get to the actual home screen it's looks crazy with vertical lines on it like a white noise effect but when I shut the screen off and then turn it back on it's gone. It's freaking me the hell out what could be causing it? Is there something wrong with my phone? Is there a setting somewhere that's out of whack? Any advice would be greatly appreciated.

sounds like a hardware issue, which ROM are you using?

Try reflashing.

I had this problem right after I flashed a kernel. Try wiping your dalvik and cache and rebooting, thats what fixxed it for me.

I have this same problem, and it only happens with certain kernels. I think it's an Epson thing. My last phone was a Novatech and had no issues and my current one is an Epson. Sometimes it's that crazy vertical line garbage, others times it's horrible tearing. It only happens after a reboot and ALWAYS goes away after turning the screen off and on. I stopped caring about it a while ago because it always goes away.

Thanks guys I rest easy now I was worried I was going to have to deal with sprint.
_MetalHead_ You the man.

No prob man. With my last phone I was very limited with which ROMs and kernels I could run. It wouldnt run any AOSP ROM and most if not all HAVS kernels were a no-go. My current one will run anything I want it to run, and runs MUCH smoother and snappier than my last phone. So, I deal with the weird screen thing and I get a phone that blows the socks off my last one. It's a fair trade off IMHO.

Ya I got worried as I'm still at noob status with this whole rooting thing and thought I fried my phone. I tried searching the forums but couldn't find the issue anywhere I had talked to sprint and they told me that it was a hardware issue. Glad that its nothing to worry about. I'm loving the boosted speed that I get from my phone.

Are you running a custom ROM/kernel or are you still stock?

Running cm6.1
Sent from my PC36100 using Tapatalk

Yeah, definitely don't worry about it then. If that's the only issue you're having then let it go, it's not a big issue at all
Have you tried MIUI yet?

No not yet.
Sent from my PC36100 using Tapatalk

Well if you are a fan of AOSP then I recommend at least trying it. I thought I was going to hate it but tried it on a whim and have never looked back.

This is a fairly common issue with cm6.1 rc1.
There's a thread in the cm forums where multiple people are getting the same thing. I would post the link, but apparently I'm too new here.

New GN froze had to pull battery...No big deal?

Hi everyone,
New GN,
ITLF41
19250UGKL1
yakjuux
4.01
I've only unlocked it, haven't done anything else.
I was only replying to a text message and in the middle of text, GN froze and the screen went black with a white line across top of screen.
Seemed to occur while the auto-rotate function was trying to rotate screen.
I also noticed the auto rotate on my GN does not work well at all. Sometimes it does, sometimes it will not no matter how long I wait.
Nothing worked, had to pull battery.
Seems fine after replacing battery.
I wouldn't be concerned but for the fact that I was not using 3rd party apps or a different rom. The force 2d option is off.
Is maybe something funky with the GN auto-rotate feature in 4.01?

Yes, versions 4.0.2 and 4.0.3 fix a LOT of little issues with the GN. They really should've released the phone with one of those 2 versions rather than 4.0.1.
I don't think you should be too worried about battery pulls unless they happen more often than you like.

Just like a computer...rebooting or pulling the battery at least once a week is recommended!

You really shouldn't be forcefully pulling the battery every week, that's terrible advice!

I'm a Network Admin for a large School Board. I know its strange I know nothing about smart Phones but I do know much about Wireless/Routers/switches and Computers.
If your rebooting computers once a week something is amiss....lol
I have servers and clients that have uptimes of 1 year+ before an update requires me to down a server or re-image a client.
In my case, if what had happened to my NEW GN happened on one of my OES2 Linux servers, Id be scrambling until the issue was found and fixed and i'd be none to happy.
But alas, a server is not a cell phone.
I hope it was a just a freak isolated incident.

You guys...I wasn't saying that u HAD to...if u HAVE to, then there's problems....but if u do it just because, it'll get rid of the little things, like the bug he has

LMAO...agreed!

I work for tmobile, at&t and Verizon! I've dealt with dumb little bugs that people have....pulling the battery is the first thing I tell them to do and 99% of the time, it fixes their bug! So why not just save yourself the time and be one step ahead of the phone!?

One very simple reason: If you pull the battery in a bad moment, e.g. right when the hardware is writing something to the Flash memory, you might (soft-) brick your phone and lose all the data on it.

Well because,
If I have to keep pulling the battery (which is NOT occurring thankfully so far) then I would say something is wrong and its not just a software bug. I would call it a blue screen of death in computer terms.
That could be anything from a hardware fault (Memory/CPU/IO sub system..etc) That would for me, mean taking it back.
A hard reset may temporarily fix the issue. But it doesn't solve the underlying problems.
I'm hoping the error was a one off. If it never occurs again, then we're good to go.
If it does, its goin back.

Same thing happened to me, the weird thing is it happened right after I completely reset the phone...

Yea its strange...
In my case the Auto rotate feature seems to be the common theme for funkyness.
Sometimes its quick, less than a second, sometimes it doesn't move at all.....
Then, a hard lock.
I realize that 4.02 and .03 fix some bugs but I have the Canadian ver. and google is not gonna update OTA for my NG.
I'm not ready for the whole, flash to "google's" stock rom yet. I just learned to unlock it...lol. If it locks again i'll try that. If it don't i'll leave well enough alone.
Oh by the way, to the Admins, sorry for not posting in the Q&A section. I though i was in the Q&A, my mistake.
Please by all means move the thread.

Actually, I have to replace cmos batteries all the time.
Usually they are good for 4 or 5 years but sometimes not.
Some people don't know what "Hit F1 to continue" means and I get calls all the time.
So yes, its quite common to have to pull a bad battery when dealing with 2,000+ PC's ...

Because I use a otterbox with my Galaxy Nexus and it's not very pleasent to keep taking my phone out of it's hard shell case and putting it back in?
Pulling the battery is always a last resort. If the phone is frozen, that is fine to pull the battery or you can hold power on the phone and it'll turn off by itself (not sure if this is in the GN but it was in Galaxy S1).
@test4echo: That's not the experience of a daily person. Not everyone deals with 2,000+ people on computers.

You are correct. Its not a common everyday thing for most.
I was just suggesting a legit reason for why anyone would need to pull a computer battery.
On another note, i agree with you that having an otterbox case makes it even more of a pain to have to pull the battery.
I just had another freeze up while trying to get back to the main page using the launcher.
Im getting worried now. I've had this phone for 2 weeks and it was great until today....
I think I'm gonna bring it back to virgin just to be safe before my 30 days is up.
If its just software then the new one will do it as well but at at least I'll know thats what it is and either wait for samsung updates or update manually.

Again....nowhere in my response did I say u HAVE to pull the battery every week....I simply said its best if u do, nobody is gonna force u to! But when u do get a bug...pull that battery, and if it keeps happening, send it for warranty...simple

Screen inaccessible once engaged in call. WTF?

Usually I can hit the power button to bring the screen back but sometimes it won't happen, like just now I hit the call button then realized I didn't want to talk, so I hit the power button and nothing happens and I can hear the phone ringing and i'm left I
With the only option to huff the phone at the wall in frustration(come on, you know a cell phone has given you that impulse before) and then the person answers and I gotta tell them in my rage, "look I really didn't want to talk to you but my phone decided otherwise, so sorry bye". Someone please help before I destroy my phone then bomb T-Mobile HQ or Samsung, whoever is responsible. Thanks in advance

are you rooted are you using a costume rom? you need to give a bit more info here, if you want help. Next post try saying Im rooted using XXX rom, have flashed before and all was well and have cmw installed or any variation above that might apply, at this point I think you are stock which I would seek warrenty.

Oh sorry, maybe I should put that info in my sig or something. I've got bombardier, not sure which version but it's old since I never kept up on updates. So maybe I should be posting this in that sub forum? I wasn't sure if it was a ROM issue. Mind you this issue isn't consistent, and sometimes it seems to just take too long, like this case after the person picked up the phone, before bring the screen back, and that the system is lagging maybe(?). I don't know but it happens enough.

That rom isn't being developed anymore, it's been long forgotten and the dev got a new device. Have you ever wiped cache/dalvik cache? fix permissions?

Not regularly. Perhaps I'll give that a shot and if no luck maybe it's time to find a new ROM. Thanks
Sent from my SGH-T989 using Tapatalk 2

Try megamix?
If you are looking for a new rom, I would recommend you looking a megamix, it's has the ICS port too.

Oh cool, thanks. Didn't know ICS was ported already

Touch screen issues return or software fix

May have to take my G back. A lot of touch screen issues where touches aren't being interpreted correctly... It is also very difficult to scroll up and down fluidly without selecting something... Honestly starting to get a little frustrated with the issue... Not cool at ALL.. Hoping this is not a bug. I actually have to push about 2-3x harder on this touch screen then any of my other phones.. If I just flick my finger to scroll through a page 1/2 the time my finger selects something instead of scrolling. That is also why I have been having so many keyboard issues. May do a hard reset tomorrow. And wait for some of you guys to get your in the next few weeks before returning mine.

I notice this happens while plugged in. I think it's a mix software/hardware issue.
When plugged into the wall with the default cable it goes retarded.
I tried again with my Nexus 7 cable/charger and it was fine.
Retarded again when plugged into my laptop.
The phone is ****ing beautiful, but **** like this makes me want to return it and I've only had it for 4 hours.
EDIT: This phone is the biggest pile of garbage I've ever touched in my life. It's locked up like apple and you can't even debloat it without it crapping out.
I'm returning it tomorrow morning.
On a side note, it's the sexiest phone frame i've ever touched.

My touch screen is fine but the stock browser likes to lock up on occasion. I am not sure how much I actually love this phone.
Sent from my LG-E970 using Tapatalk 2

In Korea, it's known issue between OG users.
Cause of unstable voltage or no grounding(earthing) in your house.
OG uses 1.2A charger, it's too sensative.
Using ferrite core cable may reduce touch issue.
Someone uses Blackberry's charger. but not sure in other country

No issues with mine. Phones are not built equally. And I don't care that's its all locked up. I don't do any of that stuff anyway. People should know what they buy. I new it was going to be locked up before I bought it. You can never go wrong with a nexus device if that stuff is important to you. I just get tired of people complaining about phones that are locked up. There are more people out there that will buy this phone that have never herd of rooting or a locked downloader. I know two people that never herd of that stuff but love and buy android phones. Now granted that I'm saying this in the xda forums so it kinda pointless.

Can you freeze it? I was planning on doing that but idk if it will lock it up also. Iv always just done that because some ota updates don't work if you don't have all the stock apps.

interesting about the grounding... kind of like a gfi popping.... hmmm. my house has no ground wires and has never been upgraded in the past 80 years so that is possible phenomenon ... phone does feel a bit cooler and my quadrant scores are also tick lower too after the firmware patch
Sent from my LG-E970 using xda premium

My EVO 4G had the same exact problem when I tried to use my multi charger (car charger but could plug into the wall socket). It worked fine with the stock charger. Probably like they said, something about the grounding or just the charger is a piece of crap.

mine works perfectly, and I just dont get the people backing on this UI....very functional

I returned my Optimus G.
I wasn't able to replicate the problem in-store, so I guess it is an issue with my wiring at home.

This thread is funny because I noticed the same thing when I was looking at the Optimus G. Except this one happened on the one that was in the store. I was trying to pick between the Samsung Galaxy S3 or the LG Optimus G. I kept going back and forth not being able to make up my mind, but noticed the LG Optimus G had a very weird touch screen. It kept randomly selecting things when I tried to swipe from one side to another. I tried turning it sideways and noticed it didnt do it then so I was hoping there was something wrong with the floor model. I went ahead and got the LG Optimus G and I can easily say I am extremely happy I did. The phone has been great so far with zero problems and its already rooted which is terrific. I am having some problems removing the bloated ATT software but that is honestly the last thing on my list right now.

I wouldn't remove att bloat yet. Freeze it at most. There has been issues caused by removing it.

I have the touch screen issue on both my lg charger and my old Samsung charger. Its very annoying. Not sure if it's worth returning the phone over because I love everything else about it but I would like to see if there is a way to fix the issue.

Noticed the bug few times too.
Not really a trouble, feels like it stops recognizing the gestures on the screen, cause simple touch actions still working good.
Pushing the sleep button fixing it.
By the way didnt happen to me last 3-4 days.

yep, i've noticed the same thing. a restart fixed the issue for now though. but yes, it was also while being plugged into the AC charger.

FYI, same issue happens with the nexus 4.
If its plugged into a usb port, the touch screen becomes unresponsive.

[Q] Screen is unresponsive with finger

I was running the tweeked rom on my Note 2 and was loving it, was running great for a few days...
Today the screen froze when I went to unlock and check a missed call. I am unable to get any response from my finger, nothing... The S pen does work though.
T-mobile tech knew nothing about how to fix it. I tried a different rom and still the same.
Any suggestions? Calibration? Anything? Thanks so much.

As it exists across roms, it regrettably sounds like a hardware issue. Have you tried flashing a stock odin? Likely won't help but it might be worth a shot.

Thanks for the reply. I am afraid that is a pretty big problem too, related to hardware. 10 minutes before the finger freeze I was just realizing how much I loved the phone with the Tweaked Rom and totally set-up.
Anyways, it's going back to T-mobile. I used Odin to flash to stock and used Triangle Way to reset the flasher... Now I am scared to root it and run a rom on the new one, but I know it was just a freak incident...
Just sucks, I hate getting a refurb replacement... I don't know what dirty, grungy, smelly pocket it's been in for a couple months, uh...

I had an issue on my first note 2 where the top right and left of the screen couldnt register the s pen, had to send the phone back. I flashed jedi as soon as i got the second one and been happy ever since.
Moral of the story, DONT WORRY AND FLASH AWAY. ur right, it was a freak accident and it wont happen again.
