touch screen problem

when i touched the screen using my finger thumb in certain area of touch screen(middle), the start menu automatically drop down
i tried my friend's unit as well, also got this problem. anyone got this problem?

Yes, i have to this problem!

how u gonna solve it? seem like this model got this problem...just it seldom happen or frequently happen

I've the same problem too! But I've send it to HTC care (I'm in HK) to repair two times. First time they change the mother broad but the problem's still there; then I send it back the second time, they change the screen as well.
I've got it back for 3 days and the start up menu didn't pop up itself. Hope it won't happen again.....

I have been experiencing the same problem for some time now.
I've had this device for about 5 months and I have been treating it very nice.
Whenever I touch a certain area of the screen (which I haven't been able to figure out yet), the Start Menu pops out, which is very annoying, to say the last. It especially drives me nuts when trying to compose something using CooTek's TouchPal.
All in all, I do not know whether this is a hardware problem or not. I'm not very sure this is covered by warranty...

same problem here, touch screen changed 2 times by htc

i take to service center, they help me changed the motherboard as well but the problem still there...i think need them to help me change the screen as well...

second changed the lcd touch screen, still got that problem but less already
happen once a day sometimes 2 days once
anyone what the problem?

You could flash stock rom with nexus rom toolkit to discard a software problem but if the problem persists, it sounds like a hardware issue and you should think about ordering a replacement if your N4 is still in warranty.

If back to stock fails too, you might try this mod to increase touchscreen sensitivity, but be careful I think only works on 4.2.2

If the issue is the same while at the recovery I am afraid to tell this is most certainly a hardware issue. You can try and install other kernels and mess around with screen sensitivity but I don't think it will help.

Mine did this after the 4.4.3 OTA update and the phone has been unusable since. A lot of other people are experiencing the same issue as well on the google nexus help forums...no word from Goog.

ya i am also facing same issue ..i am gong to repair this one from local Service center hoping for good results with less Charges

this is weird, I came here to ask for the same exact problem. I also have a part of the touch screen unresponsive, although at the very bottom (navbar unusable, I'm trying to make do with Pie Controls for now, god bless these guys. Highly recommended). Since the problem persists on recovery I though that alone ruled out a software fault, but it seems I'm not alone. I'm trying to understand, did it happen *just* after you guys upgraded or after a while? I'm on 4.4.4 since it came out and my display started acting weird only a couple days ago.
Also, did you receive any warning / strange behaviour before complete unresponsiveness? My screen seemed to registered "phantom presses" at the bottom margin of the display (in developers options I have activated the "show touches" feature), it seemed like I was on a swiping frenzy through the whole margin.

I noticed looking through google's official help forum that users affected by this generally have also experienced some sort of energy dispersion / bad isolation from whether the battery or the charging port, it's not clear. Namely, it seems that while charging from either a wall plug or a laptop / computer ghost touch phenomena and the like are more likely to happen. I can confirm these issues, although I didn't give them that much thought when they showed up.
(Also, it seems the majority of users have problem at the bottom of the screen / "nav bar").

This happens way too often. The wall charging socket at my workplace makes my phone go nuts whenever I connect it there. Touches are misunderstood (typing for instance is a bloody nightmare. Home button or recents button get "pressed" automatically). I've never seen this problem anywhere else. Looks like I'm not the only one. Hm!

Funnily enough, this phantom touches nonsense sometimes happened even when the phone was in my pocket. It would unlock the screen itself (Hellscore kernel allows swipe2wake, so phone would wake itself up) and start registering touches frenetically. The screen would refuse to acknowledge my touches; I was repeatedly forced to hard reboot the phone. This problem magically fixed itself, and reappeared a fortnight later. It turned out to be a digitizer issue; after getting the display replaced, I have no more issues. All is fine except for the mysterious wall charger touches.
Looks like my N4 loves to be touched. Dirty little boy.

Hello everybody,
I'm Maria, I came here looking for a not too much expensive solution to repair my broken glass and my touchscreen but I foud out I have the same problem ; a band in the middle of the screen is unresponsive. But my problem come out after my poor nexus fell to the ground :crying:
Now I wonder if this is closely linked to the impact with the ground or it could be the same as your problem?

Hi guys!
I had the same issue - navigation bar was untochable in any position (vertical & horizontal). Flashing stock & other alternative ROMs did not solve the problem.
So I returned my N4 to my seller. He accepted the warranty issue and replaced during the reparation:
1. Screen. So I have a brand new screen.
2. Mother board. So I have a new IMEI.
So this isue is rare and has hardware reasons.

My dad has the same issue on his phone, only happened the other day
Happens in TWRP as well
i flashed Philz CWM and the nav keys work there, also in purity if you set the nav bar to 52 (stock is 48 i believe) the nav keys SLIGHTLY work
its weird because the nav keys dont work, yet i can swipe up and get google now?

The swipe up is triggered by a point just above the home button. The bar has no work there.
<Insert witty quote here>

I been getting less and less of this after factory reset. One thing i learn is to keep my phone cool and also taking off the case. I figure that the overheating a tight grip on the phone is causing the phone to have these seizure like symptoms. Anyone know a rom i can flash to converse battery and keep my phone from overheating?

LG G2 touch screen issue. LS-980

phone was working fine but from last two week the screen starts moving automatically, Wi-Fi turns on automatically at any time. the install button of Google play doesn't work (seems like touch issue) but when i touch the same spot with camera application, it works fine. i am on stock ROM (4.4.2, kernel 3.4.0, KOT49l ) and tried resetting the phone multiple times but facing the same issue.
please help me resolving this issue.

You are just scaring ppl .. You said that my phone has probblem too .. So just dont scare ppl .. and try to help them..
i had this kind of issue with my other phone, I just downgraded to Jelly Bean and it worked fine ... and did the touch drivers update from the hidden menu 3845*#802# ...

i think you have a dead section along the top of your screen, about half an inch down. Its been fairly common. Its not real noticeable at first , bc that area of the screen isnt used often, but its EXACTLY where the play store install button is, and your knock on will no longer work. you need a new screen. or flip it to landscape whenever (seldomly) you need that area of screen. you can test it by getting LCD tester from the playstore , or by using quickmemo to draw on your screen.

This happened to me exactly, about a month back. It seems to be right across where the 2nd from the top messages are. You can download YAMTT https://play.google.com/store/apps/details?id=com.rn.yamtt&hl=en
I use the PAINT option and move my fingers around the top. It was a solid strip out near the top. Knock On will no longer work, but Knockoff will.

when i touch the same spot with camera application, it works fine.

that could be because the camera button has more "active area" meaning, it will still work if you tap near but not exactly in the same location. the install button on the play store is very very precise. if your knock on does work, then its probably just software. but if your knock on does not work, i recommend testing the hardware with quick memo.... draw lines all the way up and down your screen slowly, and see if there is a break in that area. if its not the screen, unroot, and go all the way back to stock

i don't know how but it has started working automatically form last 10 minutes and google play button is now accessible.
i hope it wont give that error again.
thanks for all good suggestions.

[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,

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!

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

Part of screen not working

For the past few weeks I noticed I couldn't respond to posts unless I removed the keyboard and brought the button to the bottom of the screen.
Then I realised that area of the screen just did not respond to anything, like in contacts I couldn't select letters in that area.
I enabled screen touches and they were showing up but there was no response from the OS.
I did a search and one fix was to clear the cache in recovery, which worked for a few hours maybe.
The next step is factory reset which I'll do if it's a permanent fix, but I'd rather not otherwise if I really just need a new phone.
No root so any backup will not be a full one so I'd rather just start again on a new phone if that's what it takes.
Has anyone had this?
Mine is the international version.

Well, today I mentioned this to work mate as it's been rather annoying so I prepared a screen to show them the issue at the store and now it's been working ever since.
Up until at least yesterday it was still happening. Very confusing as I was going to bite the bullet and backup what I could and try a new phone as it doesn't seem like a widespread problem.

Part of Touch Screen not working
I have the same issue with my S7 Edge too. It's really annoying especially when you are typing a message and can't send it because that particular area of the screen is not responding to touch. Now I have to type in a message and close the keyboard just to bring the send button down and tap on it. The issue gets solved when i restart the device but the problem continues after a few hours of normal use. Does anyone have a solution to this , Please?

Ok, my phone did reboot last night so it will probably come back.
You have exactly the same symptoms as me.

My girlfriend has the AT&T version of this phone and she has had the same exact problem the past few weeks. Like someone above said, it's right where the send button is in the SMS app.
I wonder what this issue could be?

Well, you can blow me over with a feather as mine has been fine now for about three days, since I was about to show them in the store and ask for a new one.
