Touchscreen Jitter Issue - AT&T Samsung Galaxy S II Skyrocket SGH-I727

Ok so i picked up my new skyrocket 2 days ago and I put CWM on it, made a back up and installed the ICS flavor ROM from the development forum. Everything went fine, and i didnt use the phone much yesterday, but today i noticed that i am having annoying touchscreen problems. It basically makes Swype unusable. I have restored back to stock and it was still doing it. I have reinstalled the ICS rom, double flashing it, and it still does it. Is anybody else having issues like this? Its noticable on lists. This video is just an example but it does it in the market, on web pages, etc..

I have never had these problems. Maybe take it back and exchange it.

Update:
I used odin and i reset everything to stock with no CWM and no Root and the issue has stopped as far as i can tell. Maybe i just had a bad download. Ill redownload it again and flash it tonight and see if it persists.

Ok so ive been using stock and it started again. I used an app called Touch Test to see what the screen is seeing. It is a really intermittent issue. There is a "ghost touch" that is happening. near the top of the screen and at the bottom of the screen. A touch in the middle causes it to jump to the top and then back to the bottom causing touches to jump all over the place. It is very intermittent. I didnt buy the phone from ATT so there could be 2 reasons for the this.
A) It was sold to me like this
B) The people at ghost armor put to much liquid on my phone when applying the screen protector and messed up my phone.
I didnt notice any issues before i got it ghost armored, but i only had the phone 2 days before i got it wrapped.
Any ideas on how to recalibrate the screen or any other options i may have?

Found the culprit... Kind of embarrassed it took me this long. Ended up being the wall charger. Its a cheap knock off but it had the same input and output. I was sitting at my desk on the touch test app seeing it spaz out and unplugged it to show my friend what was happening and it stopped. Used the same cable to plug into the pc and no problem. Well that is a relief.

Wow, thanks a lot for this info man! You really saved my life.
I also got a new charger and started experiencing these weird jitters. If it wasn't for this post I would never have figure it out.
My new charger was an Original one from Samsung, but it was obviously made for a different model as the output voltage and current were higher = caused jitters.
I then went back to using my old charger which came with the phone and the issue is gone.
Using Samsung Galaxy S5 NEO (SM-G903F).
Thanks again!!!

Portion of the touch screen is unresponsive sometimes!?

Hey Chaps,
Wondering if anyone has experienced this one before - my transformer is about 2 weeks old and I've just noticed in the last few days a funny 'unresponsiveness' of about 1 inch of the touch screen from the right hand side (this covers the "App, + , and Time " portion of the screen. no matter how many times I tap it just doesn't respond.
Heres the strange part, I flip the tablet 180 and i can close execute "Apps, +, and the Time" features no problems! Switching back also allows this to occur.
I'm totally baffled. At first I thought it may have been some software issue so I've tried the following:
- restart
- factory reset (twice),
- cold reboot
Still no go, I've downloaded a multitouch app and testing shows the same thing!
Cheers in advance for any assistance provided.
p.s firmware is 8.6.5.9 TW
Sent an email to ASUS to see if they will recommend anything.
Uploaded a youtube vid: hxxp://www.youtube.com/watch?v=JWAEAfXN9Jk
excuse the heavy breathing & poor camera skills - i'm sick.
experienced the same thing. i bought my tf to an asus repair center, said there was another one with the same case as mine, making me the second. they said they fixed the first one by upgrading roms. i highly doubt that though, since i tried everything from reflashing stock to rooting to a custom rom.. everytime, there's still a weird unresponsiveness that randomly appears and disappears..
neilbantoc,
I think I nailed it down - I turned it off, and left it off last night. When I started it up this morning, it was all good - I was amazed as I thought it was gone. Then it came back after 5-10 mins after some surfing / games. What struck me that I never really put 2 and 2 together is the back plate of the affected area, it was hot!
I personally think it's an over heating issue and not a software issue. The seller said it was their first TF101 returned and they have sold many - guess we just lucky we got lousy ones?
I got an exchange today and no issues so far! Fingers crossed.
Got the same problem, tried different roms, kernals.etc, will send it back for exchange.
I had a similar thing - Try downloading a drawing app and drawing lines SLOWLY down the screen with a stylus (fingers are too fat).
This may reveal areas of touch screen which don't work at all.
For mine I had a line nearly an inch high level with the speakers running horizontally across the tablet.
If you have this, get an exchange - their repair of mine failed and made it worse, and it took a month, so IMO don't risk a repair.
Guys, I can confirm that the problem has gone away with the replacement. It was definitely a hardware related issue (I still think it's over heating )

Is your phone in warranty?
can you give us some basic information? such like rom & kernel version, wether you rooted and ade using cputuningtools or something like that.
if you are under stock rom(original samsung & all further updates over kies) and u have done nothing unnormally so far i would recommend use the warranty too; )

i have not rooted or changed the stock rom
i only factory reset it when the problem started
i just discovered that when i plug in the charger the touch screen works normally but does not respond to touch when not charging

Here we go, this proves this has nothing to with CM9, this guy is on stock.
Many people are blaming CM9 for this and claiming it caused the problem.
It's a hardware defect.

Agree. :good:
I'll wait for a few weeks or till the phone is usable for the kernel 3.0. :fingers-crossed:
If not then no other option but create a Rs.5000 hole in my pocket. :crying:
Same case with me... Bought the i9003 March 2011.
I'm on DDKP3 and around the same time as the OP, my touchscreen started to act strange... responsive only when charger is plugged in. Tried factory reset, but problem came back after some hours!
If this is a product-wide issue, then I guess sammy should replace it for free, even if it's out of warranty... too busy to go to the nearest service cenrter, will check later.
Till then, please keep me updated how it goes for you.
---------- Post added at 02:31 PM ---------- Previous post was at 02:24 PM ----------
Just wondering, if a reflash of DDKP3 via ODIN or any custom ROM would solve the issue... please suggest.
I guess the sensitivity settings (or something like that) has changed without you knowing. Don't know if it is the same as s2 but in s2, sensitivity of the phone not plugged in the charger and plugged in has different settings. So maybe the settings for it in your case (unplugged) has changed but not on the plugged in settings. It's all in the kernel btw.

Maybe asking a kernel dev if the values changed or what not. If i'm correct then it's a software problem, if not then maybe a hardware problem.

Same problem!!!
It happened last week when my phone surprisingly started showing this problem. After unlocking the phone the screen becomes unresponsive. In my case it is just 1-2 secs after unlocking the phone.
It lasted for a day, I tried flashing different ROMs. I was on XXKPE when it happened. And than suddenly my phone started working fine until yesterday when this thing again happened and the problem still persists (I am still on KPE). I dont know what to do.
I think it can be some software problem as the screen and touch keys do work for some time before becoming unresponsive and even the logcat shows no problems for the touch screen. I am going to try more ROMs now. Will keep you posted.
Possible solution !!!
Friends, I think I found a possible solution for this issue. Though it seems to work for me... I have to keep the phone under observation for some days until I can say it's the final solution.
A similar thread: http://forum.xda-developers.com/showthread.php?t=1695149
The possible cause for the touch screen going unresponsive seems not to be a hardware/software glitch; but environmental issue! And it doesn't depend on the ROM your'e running.
I noticed that most people from India having this issue say that this problem started in June, when the rainy season starts and it gets humid and damp.
In fact my phone showed this issue when it had rained for the last 2 days and it was very damp and humid inside the house.
You can do the following:
1. Take out the back cover, memory card, SIM and battery.
2. Place the backside of the phone near a hot air source (on top of a running CRT TV/monitor, hairdryer, laptop fan vent) for sometime.
3. Reassemble and check if the problem has gone away.
Do not panic if the handset gets a bit hot in the process!
In my case, I left it on the top grille of a CRT TV for a day which ran for 8hrs.
Do let me know if this works for you...

Thanks to agnivo007.
I guess the climate is the only reason. I used his method to heat up my phone a little bit by charging it enough. Than it started working fine. No problems since then. Lets see.

But changing the panel solves the issue..
The kernel won't reset itself if you change the screen.

Touch Screen non-responsive Problem
I had the same issue and when i dismantlement the thing, came across a small batter. could this be the reason? Cos while charging this battery is not used but when running with battery, this small dry typed batter can be in use.
Found Any Solution
Could any 1 find a solution for this matter?
If so pls. update. Mine is still there.
I can't get rid of it.

Screen stopped working.

I'm on a business trip and have brought my Note with me which is in a cover and carried in the notebook slot of a backpack. Once I arrived I noticed the tablet, though on, appeared to be locked up, no response to touch or pen input. Forced a restart and touch stated working until I pulled out the pen and then everything froze again, including touch. Tried this several times with the same result. Did a factory reset thinking something got messed up with the software which is invoked when the pen is pulled but no help. Something has happened but to what I don't know. Was thinking about returning anyway for a 32gb version so now I guess the decision has been made. Still curious as to what happened so I might avoid it in the future....
One more thing. In the notebook compartment I also had my series 7 slate which also was in it's own cover as well. I can't see where that could have been a problem as there was plenty of room in the compartment. I guess having another semi hard object there may have stressed the screen of the note but that doesn't seem likely.

Yep, some of us have had this problem, the exact same problem. I am returning mine to Amazon and receiving a replacement. I don't know if the update has anything to do with it or not, but I am going to keep the update off of it for a while to see if the problem happens to my new one.
I've had the update loaded since the day it came out, what a week ago or so. Wasn't a problem

Same exact thing happened to my 1 week old note. Did the reset and still the touchscreen would not work correctly. Crazy thing with mine I could force a restart just as it came back on the touch screen would work fine until I let the screen turn off then it would not let me unlock. Had to return it.

Nexus S won't power up?

I recently flashed CMRex with Kejar's 4.1.1 gapps and was going about setting up my device. I got everything set up how I like with all the apps I wanted downloaded and running how I wanted them. I then ran the v6 supercharger mod that I had used on my past two roms with no problem whatsoever. After finishing the set up of the script, I rebooted my device and all was well. I went to browse on craigslist's mobile app, then I saw something I wanted to google, so I opened my browser. My browser took an ungodly amount of time to load my homepage(google), and wouldn't respond hardly. I couldn't get the touchscreen to respond. My hardware buttons did respond and I got haptic feedback from them, but no response on the screen. Eventually, after numerously pressing the home button, I got a message saying the browser wasn't responding, selected ok to close it, then back to the non-responsiveness of the touch screen and hardware buttons. And then another eventually later, after another multitude of home button presses, I got to my homescreen but everything was laggy. The most lag I have ever encountered with my device since I obtained it, not to mention that my device was beginning to heat up. So, I decided I would power off the device, remove the battery, let it cool down, and then replace the battery before powering it back up. Well, lo and behold, I did just that, went to power back up my device, and there was no sign of life at all. Tried to get into the bootloader, no response. Tried a normal boot, no response. Tried to plug it into the charger to see if it would charge, no response. Well, my girlfriend told me to leave the battery out for a while and leave it alone for a while before trying it again. So, I played some MW3 for about 45 minutes to an hour, repeated all the above, and still no sign of life. Can anyone help me out? (I don't know if this is supposed to go into the Q&A or here, so I just post here.) I'm so distraught at the possibility of losing my phone, that I'm finding it hard to cope at the moment. Should be thinking of ways to gain some money in order to purchase a new device or is there still hope?
what a long message.do you have any point form here?
i hope you solve the problem .
Do you have access to a separate charger? You can try charging your battery there and see if that works. Did you try connecting it to the computer? Maybe that will show some sign of life. Also, how old is your phone and did you over clock?

I did not overclock, I do believe that my clock speeds were at the kernel default, either 100/1k, or 200/1k. Not sure which, but definitely one of those. The only other charger I would have access to would be my mother's HTC charger, but I will try that and connecting it to the computer as well. Well, I'm not exactly sure on the age of the phone because I purchased it off of craigslist, but it's in great condition. Only had a small scuff on the top left corner, but I know that has nothing to do with the age of the hardware. ): Could it possibly be that my battery decided to die for some reason? I've been having horribly battery life lately. Granted, I had horribly battery life when I got the phone, but it's gotten worse and worse since then.
My Nexus S wouldn't start but gave a flash on the screen when the battery was first inserted. Just got it back from repair and it was a motherboard problem. Was looking at a Huawei G300 as a cheap replacement if the repair wasn't covered by warranty (which it was). Good luck!
Thing about it is, I bought the phone off craigslist so I have no idea if its covered by the warranty still. Should I try calling samsung and find out?

Testing the battery can be done differently, do you have a multimeter? Maybe your neighbours have one, it's a common thing. You can measure whether it has any power left. If you measure low voltage (below let's say 3400 mV), then it could be battery related.

If you've got no warranty, perhaps time to buy a new phone? Bought myself a new Galaxy Nexus.
I would like to get a new galaxy nexus, but I have no money to do so. I'm currently trying to get a job and i m going to save up for a new phone. Im either going to get an s3, a galaxy nexus. Either one of those two or the new nexus if it comes out.

[Q] Need help with blank screen after replacement

Hi all. I'm having an issue with a 727R. I replaced a broken screen and now can't get the screen to stay on. Its a non rooted, factory 2.3.5 phone. When I turn it on, the sghi-727r screen pops up for several seconds and then dissappears, phone vibrates once, notification sounds appear shortly and all touch functions appear to work (by sound and haptic feedback). For all intents and purposes, this phone is on and working perfectly...if you're blind lol. I know the replacement screen works because it works perfectly if I go into download (odin) mode. I've been searching threads and haven't been able to come up with a solution, as most of the other blank screens are from bad flashes. Keep in mind that I am also testing this with the casing removed as it is a repair for a friend (if that makes any difference). Any help or ideas would be greatly appreciated and thanks in advance.
Is the brightness maybe turned ALL the way down? When it finishes booting shine a flashlite on the screen and tell me if u can see text, icons etc...
I'll do that as soon as I get home this afternoon. I could only hope that's all it is, but i'm a little skeptical that I could be so lucky. forgot to mention that I have also odin flashed the stock rom back on just in case of software corruption. I would also think that I would get full boot logo's during the boot sequence, but hey!....its definately worth a shot! I've seen stranger things . Thanks for the quick response.

So you had display for start of boot and d/l mode? If so, then I'll go no farther until I get another replacement screen.:crying:. Come to think of it, when plugged in and off, the charge symbol shows up for a second and its discoloured (almost like its made of vertical lines that are pinks and grays). You may have just saved me a lot of time. I was leaning toward trying to adb error logs in hopes of finding something. Other than that it was going to be a reflow on the gpu since the phone did do a leap of faith from 6 ft up....and lost lol.

I was really hoping for maybe a fault that could be fixed with a flash.....whoa is me....looks like I may be sending screen back and getting another.
