Touch screen not responding

Well i think my Polaris has finally given me the finger.
The touch screen no longer responds to finger/stylus presses. If i press randomly for long enough it does register a click, but never in the right spot or consistently.
What do you think it could be?
Ive tried reloading different roms that have worked perfectly before, hard resets, and ive even tried taking it apart and reconnecting the connectors.
It was dropped a few days ago but it was fine, then one day, while doing nothing in particular it decided to stop responding to touch input, the normal buttons work fine.

My XDA Orbit2 (same as Cruise) has the same problemccasional freezing and touch screen decalibration (needs to be recalibrated every 5 min). problem is that this occurs infrequently. therefore i have lost hope that sending in for repair would work.....

i have a same problem..
my polaris's touch screen sometimes not responding to any touch.
i have to connect it to my computer or battery charger, and then it will work again.
can anybody explain to me why??
thanx before

same happened to me last week! well, its on its way to o2 service partner right now... guess it was supposed to brake in about 7months from now.

Hi!
I broke my touchscreen (Tytn2) and replaced it with a touchscreen from ebay for 10 €.
It works, but there are some problems:
1. I have to press very strong onto the screen for a signal!
2. On the edges i have to press very very strong - even stronger then in the middle.
3. the signal itself is on the right position......
4. i have already tried to reset the sensitivity of the touchscreen (and increase/decrease it)
5. i have already aligned the screen several times....
My questions are:
1. is it installed well?? (I had to connect 4 pins on my own.....)
2. if it gets the right signal (but only when I´m pressing very strong), can there be anything wrong with the connectors?
PLEASE HELP ME!
greetings!

Well i was SO close to just giving up and buying a new phone.
I found however, an entire brand new housing for the low low price of $65 AUS. I could of just bought the digitizer for about $30.
When i look at the devices out there...they arent that great...i was going to get a Nokia E72 but realised i would miss the touch input.
So i will suffer along with my touch cruise, checking these forums for updates on the Android progress
ANd ill have a spiffy new case to boot.

My 02 Orbit 2 touch screen has stopped working also - I found that a temporary solution is to hold the top of the screen tightly over the earpiece
It would register touches, enough to Flash back to Original ROM
It Going back to 02 this weekend.

Did google fix the sreen problem after the upgrade?

Hi, Just wonder if you still have the screen problem (register the wrong place when click) after the upgrade.

No. You should check out the humongous thread on google support forums. Googe have now abandned even giving updates on this serious problem.
http://www.google.com/support/forum...8e&hl=en&fid=04134c63c784258e00047fdfe09ae547
p.s. no fix in ere36b either (as im running that now and still experience this problem at random)

I don't understand this issue, I just don't see it on mine at all, no matter what ROM I install ... there has to be something more to this than a simple fault across all handsets ... either select faulty ones or some other factor. Mine just works 100% as expected at all times.
That said I have had no 3G issues either, no matter what radio version I use. Perhaps I am lucky ?

I think its because people are touching the edge of the screen while pressing with the other causing it to register incorrectly

That is not it, there are plenty of videos that show the touchsreen misfiring while just laying on the table. Also, the way I hold my phone I am never touching the glass surface other than with the one finger doing the touching.
With regards to some people not seeing it, this issue is very random. I can go for days without noticing it and then out of the blue it would come back, most annoying when it happens while typing something.
There is another somewhat related issue with the sensor on the n1. If you download an app called multi touch paint and try to draw two parallel lines simultaneously from say top left corner down to bottom right you will see that the lines are not straight at all and full of zigzags. Only way that this sensor recognizes multiple lines properly is if you draw perfectly vertical or horizontal lines.
There is also a discussion on developer groups where game developers are pointing out this very problem of multi toch totally being screwed up where it switches axis causing your touch to register in completely the wrong place. From the comments of the android engineer it makes it seem that the sensor hardware is just like that, cheap and low quality.

I know, I have seen all these videos and attempted to re-create many times to test I have never seen this issue once.
Don't get me wrong I can understand it being a mare of you are having it, but I just dont ever see it.

after trolling the Google thread, it seems to me there are several scenarios everyone is lumping into "screen issues" and it's going to be hard to pin it down to one source
Mine happens (touch registers on the wrong part of the screen) when I am using certain apps (Ringdroid, Browser mostly) - a couple of things clears it up ; press the sleep button, kill all tasks if you have an app for it, or change to landscape mode. For other people it's the soft keys and/or much worse. Since mine clears up with a specific action, I tend to think it is software related.

With mine it used randomly to happen but only in the Launcher (never again since 36B). I couldn't point anywhere but if I selected any app with the trackball and opend ist everything worked fine again, also the keyboard on the launcher worked well. For me it seems that it has something to do with the launcher.

love vs hate - screen sensitivity (mostly hate)

I loved everything about this Phone until today. Today is the day I tried to access ebay from my Phone. Brought up the page in only a few seconds, good start. Pinch to zoom working well, excellent.
username in without too much trouble.
Password.... it took me 20 mins to get this in due to the ****ty sensitivity on the screen. I was almost at the point of throwing it against the wall.
I have the sensitivity fix installed, is there proper solution for this problem or some way to make the screen much more accurate for typing?

calibrate the screen ,it solves allot of issues , if this doesnot fix it change the screen

change the screen, you mean have it replaced?, this is my second phone as they other was the same, are we sure this isnt something we are going to have to live with?

what was the problem?
clicking the password field (I just find you have to be quite zoomed in, in opera it seems to ignore clicks to fields unless the fields have been zoomed in on.)
or typing the password on the keyboard because it has no auto text correction? (I dont really find this a problem to be honest, I use a large number of numbers, letters uppercase and lowercase and symbols and aslong as I dont type it too fast and think about each key I will always type it right first time)

getting into the fields wasnt too bad with zoom. The problem was multiple taps. When I type a key sometimes It also puts on all the keys around it, seems to be a bit random - I havent got sausage fingers either.
It may be worse for me as I had a touch HD before this and the resistive screen was very accurate, may just need more time to acclimatise.

you probably should go into notes and try drawing lines around, if they aren't really straight or if by pressing in one spot you have the cursoir drawing all around your fingertip, then it's probably still something to do with warranty servicing
Me, on the other side, never ever had any problem with sensitivity at all, all the contrary I think that if I had to install the sensitivity patch it would be way more unpleasant to use the phone, I like the sensitivity as it is now

:S hmm that sounds a bit weird, I don't really have much of a problem with key accuracy.
are you typing your password too fast? might help if you slow it down, instead of retyping it ten times, take 5 times longer to type it the first time and you have already cut down the time it takes you by a lot

Get the original stylus from HTC and try again. If it happens with the stylus too the screen is fu.....

This is going to be a random suggestion
Do you have any Task Managers installed? Such as Dutty's/Touch X or Appelflap's or anyone that put an icon in the top right of your screen.
If so, try uninstalling them and see if this a has any positive affect on your typing.
We'll deal with a replacement Task Manager later

when I move quickly accross the page it is fine, when moving slowly its absolutely terrible, akin to sizeometer earthquake 9 on the ricter scale. I am using Laurentius26 GoldEdition V2.1, I will flash back to stock and see what that is like.
this is what I am getting, exactly..!

Have you tried using a different rom, if a new rom doesnt fix it there must be some hardware failure since that is not standard behaviour for the screen. I have just performed the same test on my phone and I get near perfect straight lines even while varying the pressure on the screen.

You say you have a fix installed is it this one: http://forum.xda-developers.com/showthread.php?t=604831

I had the none ghost fix installed but realised I have both problems. Just uninstalled and installed the ghost+sense fix and reset....
no change

will try a new ROM, if no change then I am going to send it back to VODA, this was a "nearly new" phone on their swap scheme, got it free on £20.month, seemed to good to be true and was.

Watch this video (http://www.youtube.com/watch?v=egVn2HvexhQ&feature=related). It may be the case that your HD2 needs to be sent for repair as it may just be defective.
Did you try running no task managers? I presume that it did not help.
Send it off and explain it's unusable in this state.

put stock new ROM on from Voda, a lot better by far. It must either be the ROM, the fix or Zoomer which is causing this. I wonder if anyone else has has this problem, i will log this on the ROM thread.

still having problems with this, not as bad as before, think i am going to send it back and cancel the contract, I think this phone although beautiful is not fit for purpose.

Multitouch problems on Note 3 (Mostly fixed fix by Samsung)

Update April 1st 2014: Many owners of a Note 3 these last few months have reported that their updated firmware does not suffer any multitouch issues (anymore). A few people have reported that newer firmware has re-introduced multitouch issues, so I'm still calling it "Mostly fixed". I will update the opening post if this status changes.
Below text is still phrased like the problem is "current" in many Note 3's. Will update that part soon.
------
Hi while checking my new model Nexus 7 for (minor) multitouch problems with the apps "MultiTouch Test" and "MultiTouch Tester" I also tried these on my Note 3. Here I discovered that fingers/touches kept disappearing even with only 3 or 4 fingers on my European Note 3. Just moving the fingers about made 1 or more touches disappear. Since then I discovered the problem is much more severe, and can happen with only 2 fingers on the screen, making it far more likely it will disrupt normal phone usage.
If you're interested if your Note 3 has this problem, for warranty sake or otherwise, you can either follow the written steps below or try to emulate the videos.
3RD UPDATE:
A procedure to check whether you have the multitouch defect: (UPDATED on October 12th)
1. Download and run a multitouch testing app of good reputation (I tried both MultiTouch Test and MultiTouch Tester).
2. Put 2 (or more) fingers on the screen of your Note 3 in a horizontal line in landscape mode. You can also use Portrait mode with 2 fingers (shown in the second video below).
3. Move the fingers slightly about, trying to have both (all) in a straight horizontal line.
4. After only a bit of trying one (or more) detected fingers should disappear (become undetected) or ghost touch detections should appear.
To make it easier to detect these 'glitches' you can either use more fingers (3 should suffice) or try to emulate the videos below. If you don't have the Multitouch problem on your Note 3 then please also fill in the Poll so we get an idea of the scope of this phenomenon. Thanks!
Video showing 3 fingers 'gltching' in landscape mode: (beside a Galaxy Note 1)
Video showing 2 fingers 'glitching' in portrait mode:
Video showing erratic Multitouch behavior with more fingers: (through an "unwilling" participant )
(moving your fingers around a bit you should have the same Multitouch issues with only 3-5 fingers on screen)
Ps: I included a "Have not tested yet" entry in the Poll, fully expecting a user to change his/her choice later on; the xda forum software doesn't allow changing either the Poll or your choice unfortunately.

Mine works ok with 4 fingers. But with 5 or more, it's where the problems start.
What exactly does this mean? Not expecting to use more then 2 fingers at once. It seems pointless to me. No?

It's hard today use 5 finger on the phone

It seems I would agree, but seeing the commotion on the Nexus 7 forum and the impact on control glitches while playing games I thought I'd raise the question. Better to know and understand then pure ignorance.

Agree, that's why I asked.
Personally I don't remember one single time that I have used 3+ fingers on the screen.

I had that problem too. I noticed that when I didn't manage to drift in Mario Kart. I had to change my controller layout so it is not symmetrical because the problem seems to appear when your third touch is at the same level as your first one (sorry if that doesn't make any sense, English is not my primary language).
(I have a N9005 btw).

Mine is a N9005 too. There must be many more people with such a defective Note 3 but not yet discovered it.

sounds like a touch screen driver problem. contact samsung about this. if they know it they will fix it at the next firmware release.

Did you use the built-in "show touches" feature in developers options to rule out any app compatibility issues?

Thanks for the suggestion! Unfortunately, with such small round indicators, that feature doesn't help much in discovering suddenly disappearing finger touches.
I have used the latest version of both apps ("MultiTouch Test" and "MultiTouch Tester") mentioned in the openingpost. Sofar it seems that some people have the issue and others haven't, which would indicate that the problem is inside the phone, not the app(s).

A procedure to check whether you have the multitouch defect:
1. Download and run a multitouch testing app of good reputation (I tried both MultiTouch Test and MultiTouch Tester).
2. Put 3 or 4 fingers on the screen of your Note 3 in a horizontal line in landscape mode.
3. Move the fingers about trying to have at least a couple in a straight horizontal line (still in landscape).
4. After a bit of trying one or several detected fingers should disappear (become undetected) or ghost touch detections should appear.
5. In my case I can have 3 fingers on the screen with only 1 or 2 detected.

Today I got assured from somebody working at a local (Dutch) Samsung service center that Samsung won't exchange or repair my phone with the knox warranty flag set. They will just send it back and void the warranty. I'm also sure that many more people have this defect but don't know it yet, so it could become wise (or crucial ) to check for this problem BEFORE rooting your Note 3.
I will make a mention of this situation in some rooting topics so people are warned beforehand and can do a quick check for this phenomena. On my phone it looked like a Nexus 7 type defect which I am sure a lot of (smart phone) gamers will find highly undesirable.

Yup, definitely have this issue myself. Very worrying.

neoKushan, thanks for your comment. Sofar you are only the third or fourth with this defect I am aware of.
I added a poll so we can collect data on this without everyone needing to reply (not that I want to discourage anyone from replying ).

Yes, my phone does have this problem, when I put more than 4 fingers on the screen horizontally or very closed to each other, it's shown only 2-3 fingers, sometime only 1. I dont use that many finger on my phone but it just bug me to know that I have a defected phone...

I can reproduce it after a lot of moving the fingers around but it's not easily reproducible. I'm not sure if I brought it back to the store they would recognize it as a problem since it mostly works normally. Is that how it is with others, or are you able to easily reproduce it time after time?

When I align three fingers one can disappear after messing with it for awhile. But if one does disappear and I put a fourth finger, ghost fingers appear and it spazzes out. (in any case, i have to mess around quite a bit before anything weird happens)
I haven't rooted yet, should I take to T-MOBILE and show them? Will they just dismiss it, like it's not an issue?
Is it REALLY an issue? I really want to root my phone, but I don't want to have issues later.

It can certainly be an issue (the 3 finger version at least) if you play games on your Note 3 using on-screen controls. Someone earlier here mentioned Mario Kart.

No problems here
I have the SM-N900W8 Canadian
All multitouch test apps work fine for me
All fingers move and detected perfect
10 fingers were detected (5 were mine, 5 were my co workers) =O

wtf?
first test, with 6 fingers looks good. I did some strange movements, everything looks ok.
but you are right, in landscape mode, with 4 fingers on a row,
very strange effects are visible.
2 from 4 focal points are temporarely lost.
tested on a german version gt 9005 stock rom without root, yet.

[Q] I've noticed a problem with palm rejection.

Hey guys, I just picked up my Tegra Note and I'm enjoying it, but in testing out the potential and limitations of the DirectStylus, I came across a problem and I want to find out if it's just my problem, or if it's reproducible with all Tegra Notes with the latest system updates.
Basically, I'm using the stylus, and stylus only mode is activated. This works pretty well and ignores most/all inputs from anything except the tip of the stylus.
However, I have noticed that if I slide my finger onto the screen from the outer edge/bevel, it will often (nearly 100% of the time) register this as a touch. For an example, if I tap the home button with my finger nothing happens, however if I drag my finger from just below the screen onto the home button, it will press. Likewise I cannot scroll through home screens by normally swiping my finger, but if I swipe from off screen on the left or right, it will register. Bringing down the notification area with a finger swipe, etc, all work as well when naturally this should only be possible with the stylus.
The main problem with this is when writing/drawing with my hand resting on the edge of the device. If my palm is entirely off the screen it is fine. If my palm is entirely on the screen then stylus only works, too. However, if in the process of writing my hand slides from the side onto the screen, suddenly the stylus looses focus and I'm drawing lines with my palm.
I hope I have explained this issue correctly, and I wondered if this was a known problem? If there are any solutions? Have I messed up and set an option somewhere I shouldn't have? Should I get it replaced? Sorry for all the questions! :laugh:
Oh and it's not rooted or anything. Just stock, updated to the latest system version through the system updates.
Thanks, hope you can help!

I get a similar issue at the bottom left of the screen sometimes. It only seems to effect the bottom left but in both orientations so that rules out a hardware issue. Doing a quick lock and unlock seems to fix it for me and it functions fine until next time I turn on stylus mode. Seems hit and miss with no real way to replicate it.
It didn't seem to do it before ota 2.3 so I predict a hotfix for the issue. Its a minor issue, the battery life on 4.4.2 isn't however, 4-5hrs with lite use is pretty rubbish. I suspect that's an issue with the power saving features (I think it's stuck on Max performance all the time).
Would be nice if they fix the SD write issue but Google dictate that I think.

Mine was certainly a lot worse than that - persistent on all four edges of the screen and there is no way to stop it. 60-80% of the time it was manageable, but consistently reproducible, other times it was far worse and could only manage dots and dashes when I tried to write anything while resting my palm on the screen. It also developed a 'blind spot' problem I've noticed reported on a couple of forums - a spot where the stlus simply refused to draw - so I grew more concerned that I had a problem with the actual hardware. So, I took it into the store I bought it from, and they're going to replace it for me.
Hopefully I won't have a problem with the replacement one, because I absolutely love the tablet!

I've had similar problems... just remember, all of the stylus functionality is governed by software; the screen on this is simply a regular capacitive screen that's also capable of detecting the size and shape of what's touching it, and the rest is calculated by software. It's a neat idea, but in practice it hasn't held up as well as Nvidia would've liked us to believe. Now that I've had a Galaxy Note 2 for a couple months, I have to say that the active stylus experience blows the TN7 away, but then again it's a much more expensive technology to implement. I almost always used a pencil with my TN7 while it was my day-to-day work buddy since I found the stylus to be too sticky and hard to write with... I also found several of the issues I was having weren't as bad while using a pencil, so maybe you could give that a try. Also, remember that if the screen is dirty that it will affect the stylus's performance as the screen is so sensitive that even a little moisture could register as a touch on the screen.

I received my replacement tablet today, and it is a lot better than the one I previously had. While the problem is still there, it is far, FAR better than before. Now it seems to be a minor nuisance, rather than a consistently reproducible problem. On top of that it has a much more vibrant screen - less yellow and washed out - and no 'dead zones' when trying to write with the stylus. So while I am certain software has an impact on performance, there must have been something weird going on inside the hardware of my previous device, too.
Considering the price, the fact that others have had similar issues, and how much I like about everything else - I'm very happy with my new TN7 now!

Have same problem .... When i swipe from left or right side of the screen it detects stylus nd do all the things.... Dont knw wat to do amazon is not replacing too the tablet..!

Same problem, I don't usually mind it other when I'm using an app like sketchbook pro, it becomes really annoying.
