My phone has been working perfectly with JM5 & samset v1.9f with CFlag fix v1.80.
Then the other day I noticed the screen was shaking slightly when I held my finger on the screen, as if it couldn't locate where my finger was correctly. Also it shakes alot more severely while it's charging.
Has anyone heard of this problem before? Could it be a software fault that reflashing firmware will fix, or is it a hardware fault.
Please help!

it's called haptic feedback
it's on by default, you can turn it off from Settings
is that what you mean? or it's something else?
Maybe it's the touch point itself which doesn't register correctly.
Are you using an aftermarket (non-Samsung) charger? I remember reading about someone else having trouble with the touchscreen going bonkers while he was charging the phone on a non-standard charger, which for a capacitive touchscreen might indicate some kind of electrical grounding issue, (edit: or maybe not (link)).
edit: Maybe you can try discharging the screen by wiping it with a soft cloth used for cleaning vinyl records.
I have only ever used the charger that came with the phone, and the usb that came with it to attach it to my laptop.
The problem still exists while it's not charging, it's just alot less severe.
I'm going to have to flash it to stock firmware and hope that fixes it. If not I'll have to send it out to be repaired.
I hate phones sometimes......

I should also add my screen is perfectly responsive, there are no dead zones.
It's as if the touch screen can't tell which part of my finger is touching the screen. For example; If I put my finger flat on the screen rather than the tip of my finger, it shakes alot more.

Thanks for your help, I read the link you posted, very helpful. Maybe the charger was faulty and that damaged my phone overnight?
I tried the charger at someone elses house and the increased screen shaking still occurred. But if I connect it to my laptop by usb, it reacts the same as when it's unplugged.
I will try wiping the screen with a vinyl cloth when I get home. It has got a screen protector on, but I can't imagine that affecting it.

definitely not the screen protector
i have one installed, and i don't experience those screen shakes you described.
I found this interesting thread about someone having very simular issues: http://www.droidforums.net/forum/te...tions/31237-please-help-droid-has-shakes.html
It hasn't helped in solving the problem, but at least I know I'm not alone with this issue.
Edit
After reading the post more carefully, it seems that this persons issue somehow fixed itself.
Perhaps the best thing to do is check if this issue is covered by warranty (so I can send it to be fixed at a later date if problem is still there) & see if mine fixes itself too...

i used to experience this on my HD2 and Milestone, i must say that the galaxy S'es touch sensor is one of the best and have very seldom experienced this problem.

Yes my problem is simular to that, but it's only that bad when it's charging from the mains.
I'm going to flash to stock firmware tonight. If that doesn't sort it I'll take it to a t-mobile shop & see what they suggest.
Apparently I've got 2 years warranty so if it gets worse rather than 'fixing itself' I can always send it to be repaired. I just don't want them to give me a refurbished one, knowing my luck it will be full of dead pixels...

Sounds like something interfering with the contact between your finger and the screen, or faulty hardware. ( Screen protector, wet fingers. )
If you are reproducing increased troubles with charger than it may very well be faulty hardware.
I can also attest to the high quality of the Galaxy S's touch screen, it can track 5 points very accurately.
It's not the screen protector as it was working fine with it before Tuesday, when the problem started.
I'm going to flash the firmware tomorrow when I have time, if that doesn't fix it then it must be hardware. I'll report back.

Intersting...
Ok, I flashed JF3 and the problem was still present.
I went to a local T-Mobile shop & showed them the problem. They basically said the phone still functions correctly, and recommended to stick with it and possibly get it repaired if it gets worse at a later date, which I fully agree with as I could get a refurbished phone in a worse state.
I reinstalled JM5, samset v1.9f, and used the update.zip ext4 instead of Cflag fix. I notice for some reason the problem seems less severe, but that might just be imagining it.
Thanks to everyone who helped.

I'd take it to an official samsung service point. There's no way a phone salesman would have a friggin clue about whether or not that's safe. It might make your battery explode and blow your nuts off if theres some shortcircuit in the phone or something...

I am using a HD2 and I noticed this problem when the phone is plugged in with a laptop. With Wall Charger, it works fine.
open up
i had the same problem with another phone. i tried everything. after that i just turned phone off, get all screws out of the back side. i pressed all connectors and after that put the plastic on it, turn the screws back in and restarted my phone. now i never got the problem anymore
NOTE: if youre not sure about what youre doing, ask somebody who know he can!
Kind Regards,
So for some reason, my screen keeps recognizing clicks that i don't do. In another way, it clicks on itself. I can leave it on the table with the screen on and by itself, it will make a phone call, or open an app or something. It only clicks on stuff that are in the bottom 1/5th of the screen. Its on every rom, not just the midnote 2.0 that i am using.
Anyone have a solution?
Sounds like a display issue. have u recently sat on it or maybe applying pressure to that part of the screen? or it may be cause by magnets on cases etc....not really sure if it can be fixed unless u replace the whole screen entirely...
Same screen issue!
My Galaxy Note just started doing this as well. Mine is on a stock rom, and I've tried a factory reset and it hasn't helped. I'm wondering if there's some sort of screen diagnostics out there that can help identify the issue. The problem is intermittent, but sometimes when it gets going its just click after click after click on the same spot...
Nope I haven't sat on it. Do you think Samsung would fix it under the two year warranty?

After the factory wipe and reset do you check to see what applications are running? Do you have absolutely no other apps that have been installed?
There have been some early warnings of virus being written for android so I have used an antivirus program for last eight weeks and never had a problem - perhaps you have an unwelcome visitor?
Otherwise definitely go for a replacement, especially if the phone is only a few weeks old.
I use an antivirus app that I downloaded from the market a little while ago. I ran a scan with it and there is nothing wrong so I guess that my best bet would be to get a replacement. Will Samsung replace it even though I am in the us?

Just got a droid 3 from Asurion to replace the D2G I cracked this weekend, and I don't want to sound like a whiner, but I'm not too impressed with it. Not liking the unlock button placement/it's hard to push (lawl), and the keyboard isn't as good (except for the number row that's nice), stock is kind of sluggish, and the screen seems kind of pixely and fuzzy in some places. But the biggest issue that I just found is that if i shut the keyboard at any speed slightly above average, the phone restarts completely. Does anyone else have this issue? Could it just be because it's most likely a refurb? Sorry for the complaints haha I'm just a bit disappointed but i'm sure the phone has its good qualities
Sometimes this happens to me as well, but not always. I think its the battery, when you shake the phone you can fell the battery moving + restart

If it is the battery what you can do is take a piece of scotch tape and roll it end to end and stick it between the battery door and battery. As far as the lag wait until CM9/10 is done.

At one point I tried a third party extended battery I found on Amazon and it caused this exact problem (and also restarts at other times). The fit of the battery was kind of loose and when shaken or handled just so, it would restart. Is it a refurbished phone? Refurb or not - check to see if it is a Motorola battery in it. If it is the battery being loose causing it, I'ed request another replacement. You shouldn't have to mess with a phone they just sent you to make it work.

thanks everyone, and yeah i think it's a refurb, sometime it shuts off randomly too. but it is strange because even if i shake the phone it doesn't shut off, only when i close the keyboard too quickly (which is any speed except slow and cautious), so i dont think its the battery being dislodged but who knows. it's def the right battery, but i think i might call asurion because i cant really deal with random power downs
Hi,
The current problem is that my phone signal keeps cycling between full bars and no bars, or is not connected to a service. Checking the phone signal strength, it seems to be hover around -100 db or so.
So I did a search on the closest thing that I could find was this one.
http://forum.xda-developers.com/showthread.php?t=1894486
So what I have done is the following:
1. Had an issue with charging and holding a charge when upgraded to Xperia X ed rom
2. Did some research and figured the easiest option would be to reload the first ROM and check if the issue still exists
3. Reloaded nandroid backup to the original, same issue
4. Cleaned out the USB port using some thick paper, rubbing alcohol, compressed gas and small vacuum, same issue
5. Did some more research, figured that it would be easy enough to replace the USB board, so replaced that (reconnecting the antenna)
6. Turned on phone and used the first custom rom on there, everything seemed to work fine but I didn't check the signal strenght
7. Upgraded to SweetROM v10, only then noticed the signal issue, unscrewed the back and checked the antenna connection, seems solid
8. Tried to use it for a day and it's really bad, most of the time inside, I can't get any signal but outside, I normally get full bars
9. Did some more research, remembered something about modems, changed the modem from XXLT3 to XXLSO, just incase it was that, still the same signal issue
So wondering if anyone can help me with the next steps. I figure I am gonna tinker around with it a little, to see if it is a software thing. I figure what I will do is the following:
1. restore back to nandroid - check the signal issue
2. if still there, maybe try a stock ROM
Maybe take the cover off again and check the antenna cable, could have damaged it pulling it back in the first time, however, it doesn't make sense that signal strength would not change that much but the reported signal would.
Any help would be great.
Anyone with any ideas?
Where did you source the replacement part, is it stock samsung and are you sure it's the same revision?

i have totally in same position. i have damaged usb port, couldn't charge. then buy an 5$ usb bord that same rev with original one. But reception is totally unstable. Especially when driving, reception have (nearly) always zero bar. And inside building reception is half of original part and also unstable. Tried most of what u tried, no luck. i think i have to repair original one(i opened inside the phone, all usb port pins broken from thecorner point. Just have to replace usb port )

So long as you use a stock replacement part and not the eBay alternatives, you'll be fine. These problems occur with the imitation parts.

I was pretty sure it was the same revision but it could be imitation. I suppose will have to take it in and get them to do it. Just it takes them weeks to do this type of stuff.
Not sure where will it take weeks. I got mine did in just under 2hrs.

i went to a few SC and checked if they had the part and one of them had.. so they did it instantly... you will need to do some field work if you want the phone soon..
I can confirm this issue started with my note recently after a ROM flash possibly 2 months ago. I tinkered around just like the OP and I can confirm with a high level of certainty that it isn't a hardware issue. Reverting to stock didn't help much, but using the same ICS modem with which the phone initially came with made the Wi-Fi more stable. However, those spontaneous disconnections are still happening, and with them the phone lags and freezes most of the time. I replaced the USB board with a genuine one from broken screen old note. Everything seems functional apart from the intermittent yet frequent Wi-Fi drop outs. I'd love insight into this matter too.
Added: Wi-Fi just disconnected and reconnected while typing this post by the way.

Nope. That's hardware issue,at least ours are. if i use original board no problem occurs(except no charging couse of broken pins), then if i use new usb board problem occurs about gsm reception that explained above. I think your problem(wifi) and our's(phone signal) isn't same.

@ nokiamodeln91 - thanks for the tip, will be trying that. I have done some asking around and I think that I might have an alternative but will need to test it out this weekend.
@ juliobahar - sorry, my wifi signal is strong and constant. By phone reception I mean carrier signal. I have done a fair bit of research on this since logging this question and 99% of it points to hardware issues. I have gotten some new software to track carrier signal via map location (hope this will be able to give me a little more insight into it's performance) and it just seems to be weak (i.e. either a connection isn't quite touching or it just isn't up to scratch) so that when indoors, it just doesn't have the juice to receive.
@ maktama - yes, it is almost certain that it is a hardware issue.
any further updates on this issue? i damaged my usb port a few weeks back and ordered a replacement from amazon ( http://www.amazon.co.uk/gp/product/B009X6BGDM/ref=oh_details_o02_s00_i00?ie=UTF8&psc=1 )
i replaced it following a guide on youtube and initially everything seemed to be fine. i could charge again, signal SEEMED fine, and even my mhl adapter worked and i could view the phone display on my tv, so i binned the old usb module.
since then though i've noticed some serious problems with my signal. sometimes (though not all the time) my signal strength drops off terribly indoors. even in the car my strength can go from full bars outside the window to 0 bars in the car, especially if i have my charger plugged in. it's very inconsistent though, in some places i've noticed very little change to signal strength. wifi seems fine though and outdoor use appears to be as good as it ever was!
is there any point flashing another modem or even completely reflashing my phone (i'm running a fully stock rom though i am rooted) or is this definitely a hardware issue that can only be resolved with a new board? i'm due a new phone in february anyway but it's a bit of a pain not being able to rely on having a signal even when i know i should have one
There has been lot of similar issues replacing the usb module from sellers other than Samsung service. May be the antenna connection was not made properly. Open it up again and do a thorough check. If all Ok, then you might need a genuine part.

sorry i should have said i did re open the phone and checked all my connections.
any idea where a genuine samsung board can be bought, and is the board revision really as critical as people say? as i said, i stupidly threw my original board away because i thought the new one was working so have no idea what revision my board was.
Genuine part from the Samsung guys. Most of the time it's Rev 1.0. Yes the Rev is important.

Hi.
I have the weirdest issue: My screen flashes when I try to turn it on, but refuses to give me any picture. Here's the weird part: It only happens when the phone is cold (approx under 22c, 72f). Now to be clear, the screen works at any temperature I've attempted to use it in. It just won't START in those "low" temperatures. When it's running it'll keep running with zero problems.
The touch works when I attempt to turn on the screen, regardless of if it actually turns on or not.
I've tried complete factory wipe, and even downgraded the OS via the huawei program on PC. Only difference was that sometimes when it would have flashed it gets stuck on a green glitchy pattern.
I'm fairly proficient in electronics, but I can't think of any reason why it would act this way.
It's clear I'll have to send the phone for repairs, but I'm out of warranty so I'd rather find a fix I can do myself (even if it's complicated, I've got access to microscope and fine soldering equipment), and MOST IMPORTANTLY I want to figure out WHY this is happening.
Tell me if any specific information could help figuring out what is wrong.
Send to service... replace screen in warranty...
my p20 pro also did it... i walk to service, replace screen in warranty within 3hours...

Update
So, interesting update:
I dropped my phone, and it slammed into the floor quite hard. It seemed to have fixed the problem. Now I REALLY want to figure out what was the cause of the problem to start with!

Looks very much like an unstable contact that was "slapped" back by the fall. If you really want to know what was the issue you should open up your phone and tell us all.

How would temperature effect an unstable contact?
I would open my phone but I don't have a heat gun.
Thermal expansion, maybe?
I think mine does the same thing. Only ever notice it outside, where I have to keep trying to open my screen, while it keeps flashing, and when I wake up in the morning and usually have to fully restart my phone to use it.
