[Q] Erratic and unresponsive touch intput!

All of a sudden, the screen is unresponsive and responds erratic to my input. It just happened, the phone was fine while using it the whole day. No water, no drop, nothing appears wrong with the screen.
I turn it on and it works like it should...but after a couple of minutes, it starts getting crazy.
I left it on the shelf for 3 hours and now it wont hardly recognize my fingers. If I swipe left, it pulls down the notification meny. If I try to pull down the notification meny, nothing happens...what gives?
There is no water damage in or on the screen and there shouldn't be, because I'm careful with that (now). I don't drop it at all almost and never from any hight. Its only normal use and I've taken care of this better than any phone I've had.

Have you tried a reset? Even though I doubt its software related, I'm thinking the screen has cropped out on you.

Wipe a few caches, see what happens

Did backups and a factory reset.
In vanilla, the phone seemed to work as normal. It was faster than before that's for sure. BUT, it was impossible to pull the notification bar down. Everything else works and no apparent problems arose.
BUT, then I installed ADW.Launcher again and the phone flippet out. Same problems as before, unresponsive and erratic touch behaviour. Strange....
Changing to Sense stopped this, but still can't pull down the notification bar with a swipe down. I can open it with pressing "Menu" button first though.
Seems somethings wrong with the upper part of the touch screen and ADW somehow tries to use this and the touch function stalls.
I don't really thing I can send it in as a warranty, because it has 3-4 bumps in it and they will use this as an excuse not to open it. Shame...

Unroot and try for warranty methinks. Otherwise, I can't be of much more help

screen non responsive after wake up

​Had my vega for just 3 days, i left it on charge on the first night and when i tried to use it the morning after the touch screen was more or less completely dead, only a 1" stripdown the left side in landscape mode was responding to touch so i couldn't even unlock it without using the wake then press the back button method - even then the screen was non responsive.
I did a reboot hoping this would solve it but no change, anyway after leaving it off for half an hour and rebooting the screen started to work again and I had no further issues that day.
that night i let it go to sleep again and had the same issue again this morning, the screen was non responsive after a prolonged( 6hour ) sleep
this time i decided to see if it was software so put it into nvboot mode and flashed the modaco rom, - after getting the new rom up and running the screen was still lazy, serious dead spots in terms of touch, i let it go to sleep for a few hours in the afternoon and tonight the touch is not working again.
I bought it online from dixons, and tbh the box appeared to have already been opened when i got it.
I'm starting to think its a faulty unit with a serious hardware fault - has anyone else experienced the same - did you find a fix?

Have you tried running the screen calibration tool, i think it is included in the modaco rom. I have not had anything as serious as you seem to have (only a slight dead spot in the bottom left corner of the screen, which the tool fixed) might be worth a go, if you have not tried it, before getting a exchange.

thanks Ganjaman, cant get the darn thing past the accept terms and conditions screen after a fresh install of stock rom because i cant press the accept button because its in a non responsive part of the touch screen.
dont think i have any option but to return it

Bad luck! Hope you can get a exchange in-store.

Have flashed the new 1.09 rom and it seems to have fixed the screen issue.
What was interesting. Was that if I warmed the tablet up slightly near a heater the screen would slowly start working again. Ganjaman, will your 1.08 update add market to 1.09

I am going to remake it for v1.09 shortly, i need to remove flash change the build.prop and i am going to add usb switcher. Glad you sorted it.

"Jerky" / not accurate screen (video inside)

Anyone has this problem? When I put my finger on the touchscreen, screen moves up and down like crazy. It gets worse when I move my finger to the side of the screen.
I tried different roms, different kernels, nothing fix this.
Only when using the touchsentivity app and changing the value to any value and clicking apply makes this behaviour disappear for a moment.... after locking the phone and awake it, same thing happens again.
It drives me crazy because I always put my finger on the screen when reading something.. or in some apps or games when I need my finger stay on the screen it gets annoying. .

This isn't normal. If you can't solve this problem with a factory reset, get your phone exchanged or repaired.

That's what my HD2 used to do. Couldn't type anything on it to save my life. Think I'm gonna have to check my SG2 now I've seen your vid.

Thats probably because the custom kernel your using has a different value for it and the app is setting up 5, try it with a stock kernel and perform a factory reset and see if the issue still occurs w/o changing the TSP value.

I got the same problem. I do that sometimes too.. scrolling up and read while holding my finger down, it just jitters or something.
You're not the only one, but not sure how widespread this problem is or if it is normal or not..

Mine is also jerking when holding the finger out at the edge lol, looks retarded

Interesting...so if I disable the touchscreen fix the problem goes away. If I reinstall it, no matter what the settings are, I get the jittering effect at the very corner of the screen.

Yep I got same problem, when reading and holding down on the screen it does the same.
On Litening Rom 1.5 cant remember if it happened on stock rom though

I get this too, my SGS did it as well.

I tried this multiple times on the edge and it does not jitter at least on the phone that I have.

Mine did this when it was plugged into the mains (using a non-samsung) charger. Does not do it when plugged in via USB or on battery.
Is yours plugged in?

So some have it, some not?
I always had this thing, since KE1.. now on KG5. Stock kernel, custom kernel, rooted or not rooted doesn't matter.
Also, it has nothing to do with the touchsentivity app. The app even fixes it temporary when applying a new value, but it re-appears when locking-awaking the phone. (I tried to enable the service option on the app, so it will apply the value everytime I awake the phone, but this does not work)
I just tried it when plugged in in the changer, it seems to do the opposite... when plugged in I don't have this effect anymore. Once plugged out it starts again.
I also have SGS1.. this does not happen.

So how has this worked out for you? I have this too but just a little bit less. It also stops for me when plugged in. I wen't back to the store with it but saw that the shop model had the problem too so I decided to not return it. How about you?

I checked and it appers that i have i too. Didnt notice it till now.
It is occuring only on the left side when holding my finger.

I did not notice it too...and yes, mine is "Jerky" too...

Mine is fine, so looks faulty to me.

weird left side
I have to say this happens to me too but only when at the VERY edge of the screen,on the left.
There is something very weird about the left side of the phone.
1. the touch issue
2. the yellow tint
3. the glass is more raised than the right side(check it out) its like there is less bezel showing on the lower left part of the phone than the right side. I've checked 3 s2s and they all had it.

I have this all over the screen but not as bad as on the left side. Could someone install note everything and make a paint note with the smallest brush. Then try to make some straight lines (without the phone being connected to the a/c). Draw them really slowly from the left to the right. Mine usually jumps 1 pixel up and/or down and is a bit wavy (which isn't normal for touchscreen phones cause I tried the same thing on my friend's optimus 2x and the lines where as straight as could be). Maybe if you guys make a screenshot (home button+lock button) we could compare them and see if there is really a problem with specific phones or with the Galaxy line in general.

This was something I noticed when I first got the phone, if I kept my finger on while browsing, it would "shake" and be extremely annoying. Same thing happens when you hold an application in the left corner of the screen.
If my phone is charging, the problem is gone! It's smooth, and doesn't "shake".
Soon as the charger is removed problem is back
Going to return this tomorrow and see if they'll exchange it.

Just another 'my phone is red, yellow screen thread'. Does it affect your day to day usage? If it does,i too is concerned.if not, then what's the point in looking for non measure issues? This issue was up like 4 months ago and now, back. Y'all just return your phones and close annoying threads.

screen/backlight issue, tripped knox phone, what to do?

I'll preface by saying I am an IT professional for work so this is no noob request.
So, this all started with my capacitive buttons acting up. I have CWM (tripped knox), SlimROM. What was happening was when my capactive buttons were lit and then would dim... whenever I'd press ANYWHERE on the screen (with the capactive buttons dimmed), it would press the back button for me. Made no sense to me, sounds weird I know. Never got around to trying to flash a new rom or anything, just ended up permanently having the buttons dimmed.
Fast forward a few days... in my car in the cupholder, spilled energy drink where my phone was sitting in cup holding. Probably only an inch high or so with my phone upside down (home button to the sky), so the charging port side was safe. That day is when it went south. I'd hit the power button on, screen would come on. Power button off and on again, screen would not go on (but capactive buttons WILL light up, and digitizer works and you can hear the audio). Off and on again, maybe came on. Intermittent. Put in rice for 36 hours. Same thing. Note that when the screen IS on it is perfectly fine and usable (the capacitive button problem is gone now too....). I set the display to turn off after 30 minutes of inactivity. It's been on for like 10 right now and hasn't flickered or nothing. It's just if I turn the phone off, and back on, chances are it will not come back on (but capacitive buttons always light and touch screen and audio still works). It seems to only come on when it's been left for a while. Like if I turned it off now, and went off/on/off/on/off/on it would probably stay black until i left for 10 minutes and then might fire on.
My Note 3 model is SM-N900W8 (Canadian TELUS). Behind the battery there is a speck of a circle that is pink looking. Unsure if this is a Liquid Damage Indicator. Another CLEAR liquid indicator on the top left when case is off is clearly white, the LDI on the battery is white. Had a hard time finding image that shows the LDI's. Anyway, KNOX is tripped. As far as I've researched I cannot change this. I do have a CWM image of the stock Samsung firmware. But, there is no point in going through warranty at this point (phone IS under warranty though) unless I can revert KNOX, and confirm the LDI's are all white......
I am thinking this would be a relatively easy hardware fix though. Everything seems to work perfectly fine if the screen IS on. It's just the screen getting on being finicky.....
Any suggestions?
Currently getting all data off, and then will try flashing another firmware etc. but this really seems like a hardware issue.....
Thanks for any advice!

So how did it go?
I would just bring it to repair, it's better to lose a hundred canadian (send to repair or fix yourself) than to bear with a broken phone that doesn't sleep properly.

Test the proximity sensor and ambient light sensor.... If you have any "pocket mode" or active display features active in your rom try disabling those... Sounds like your warranty is definitely void but you could take it to a local independent shop if samsung wants too much to fix it.
Good luck!

Since I cannot stand when I research an issue, finally find someone with the same question and turns out there was never a resolution response, I am going to say that much to my shock, reflashing to my stock Samsung TouchWiz nandroid fixed the issue. I then clean flashed the latest SlimROM and all is well. I had dirty flashed to the latest (stable) SlimROM 4.4.4 and it worked fine for weeks which is why I had little to no faith a reflash would fix. Especially since the screen would be blacked out during the boot screens. That is baffling to me. A custom ROM/kernel should have no effect prior to the ROM booting should it? I guess I am wrong on that? Regardless, happy I did not have to work around the KNOX being triipped....

That's so strange, but congratulations on fixing it.
You should have a boot animation with any ROM you flash, just remember to check your MD5's to the developer's MD5's after you download.

[Q] momentarily unresponsive touch screen

Hi guys
I have moved from iPhone to a note 4 and loving it!
I was just wondering if anyone has found the touch screen occasionally doesn't respond to their touch and you have to touch it again. On the iPhone it only ever missed a touch if my finger was in the wrong place, but it never happened on the keyboard. Every so often maybe 5/6 times a day I touch a key on the keyboard and nothing happens, when I try again it's fine. I can't reproduce it, because when I tap anywhere on the keyboard something gets pressed. I was just wondering if this was normal?
Hope you are enjoying your phones!!

Anyone?

It's most likely cause your palm is on the phone. One of the downsides of a slim bezel on a big phone. Also keep in mind if your spen is on the screen, your fingers won't work. A case might help.

I thought about another part of my hand touching the screen, however with half my hand layed across my keyboard I can still type with the other hand. Thanks for the response

I Pele tried factory resetting today and not installed any apps, but it is still happening

I rang Samsung this morning and they advised I return I to the store and get an exchange. Luckily my local store got its first batch of note 4s in this morning and they swapped it out. I restored it all firmware updates put on it and now works fine! The only thing I haven't installed is a Google play system update thing. I was wondering if that was the cause x

Similar issues
I've had similar issues (in fact, that's what brought me here in the first place). Initially, I was able to tap on the screen in the text box and then continue typing (I use Swype). However, now my messaging app (default Messages) just freezes up, forcing me to close the app, clear the memory, and relaunch the app before continuing.
Were you using the default app and/or Swype when you had issues? I'm going to try to factory reset my phone to see if it helps.
It's taken a couple of weeks for this problem to develop, so please keep us posted if this problem arises again on your new phone!
Edit: Also want to point out that when I text, I use one hand to hold the phone and only a finger to swipe my text. As such, only the one finger touches the screen.

unable to use touch screen. only hard key were working >>Note4
Hi everyone,
today i just had the same problem with the touch screen. no response at all .. after i tried and took out the spen .. and surprise it worked with the pen.
tried again with fingers still nothing worked, so i used the pen to reboot the note4.
hope my experience helps.
cheers,

Same thing happened to me last night. The touchscreen became unresponsive while using chrome. The phone was a little warm but not bad. I didn't try the pen, sounds like a good idea. I am not certain it was a touch screen issue with mine. Almost more of a processor issue. I got the phone to lock. After pressing the menu or lock button to wake the screen it would take 5-10 seconds to wake. Then I could swipe my unlock pattern. It would not show any lines. I would wait, the screen would turn black after timing out in about 5s. The about 5s after I could hear the speaker make the unlock sound. I ended up doing a battery pull and that fixed the issue. Anyone else have something similar?
Should I try and replace it?

Observe to see if it happens when you're using other apps too. Chrome has been notorious for causing all sorts of problems, like reboots, freezes, etc on some devices.
Also it may be worth installing Chrome Samsung Support Library.

Got the same problem after 2 months of normal usage... I initially though I had installed a third party application which was causing the system freeze but this was not the problem.
- tried factory resetting and not installed any apps, but it is still happening
- When this happens if I take out the spen .... surprise it work. The pen allows me to do anything... But the touch screen does not work with fingers...
- I used the pen to reboot the note4... Still the same problem after reboot... I ended up doing a battery pull and that fixed the issue for.... a couple of minutes... Then the problem came back....
The only solution remaining was to return the phone.... They gave me a Note3 while my Note4 is being repaired...
That's a shame for a product of that price!
:crying:

Same thing is happening with my 2 months old note4 since two weeks ago. An horizontal line 1.5cm in width about 1/3 from the bottom of the screen, became unresponsive. At reboot it works sometimes then it becomes unresponsive again. It looks like in the image I attached, the difference is that the area is horizontal, not vertical. I'm taking my note4 to the store today for warranty, hopefully they will replace it. I haven't abused the device in any way, I have a screen protector since its first day.. I really hope this isn't a serious problem that affects many users.
Just like some of you mentioned above, the pen has no issues on any area of the screen.
Cheers!

same thing happen to my note4 today. the only difference is that yours was fixed for a couple of minutes after removing the battery. my note4 wasn't fixed after that. Only S-pen works, touch screen with fingers wont work. you mentioned you're note4 is getting repaired, did they tell you what may have happened to it so that i'll get an idea of the cause..

Never purchase a device without a return / DOA policy. Not worth the hassle. If it hasn't been 30 days, you should call your credit card company or Paypal and place the amount on dispute, wait, you purchased from another market, please tell you didn't pay by cash.

I have this problem after I flash CWM recovery, before this was flashed with twrp recovery, I reflash stock rom with odin, I flash many times CWM and TWRP and I still have the problem, my warranty it's void now but I think to go at Samsung store to see if they solve my problem. This problem look like a driver for touch corrupted, if somebody find it out how to fix or have any ideea please weritte here, thanks you

I've started to have this problem as well, lower part of the left side of the screen sometimes registers touch instead of scrolling! Very annoying, tried to update recovery, tried tapping screen, doesn't help. The worst thing is I cannot reproduce the issue at will... It seems pretty random.

Unfortunately, if the phone is on Verizon, the dialing codes will be disabled.

Potential fix.
Please excuse the necropost But I came here looking for a solution from google and others may too. I found a way to solve this issue/s.
There appear to be two issues affecting this.
1. Overloading the processor.
2. Static.
If your touch input is lagging or doesn't register at all but then suddenly does a few moments later, its likely a type 1. problem. I fixed this by disabling resource intensive features such as s voice. This also improved battery life and overall performance considerably.
If touch simply doesn't work at all, but s pen works fine then the problem is more likely type 2. That being static buildup in your person. Simply touch something that can ground you and it should fix the issue. A metal tap should work. Be wary, you might even get a little zap as you discharge
