A friend of mine brought me his Wing to look at for him. If I turn on the phone on it boots up and the screen looks just fine. When I slide the screen opened to use the keyboard the screen freezes and when I close it again it gets all jumbled up. There are lines going through it and I can not make out anything. The phone isn't locking up at this point because I can press menu buttons and other hard buttons and see the screen react, I just can't tell what is happening.
I assume that this is a hardware problem. I was thinking that the cable that connects the screen may have been jarred loose or damaged in some way. If that is the case do you think that it would be as easy as opening it up and repositioning the cable? I don't have any experience with this phone specifically so I don't know if this is a common issue.
I was also wondering if it is possible that this is just a software issue. Maybe the function that rotates the screen for use with the keyboard is messing up and jumbling the horizontal and veritcal lines when going back and forth. I was thinking about doing a hard reset and seeing if this clears up anything. Any thoughts?
I appreciate any help. This forum has always been there when I needed help in the past. I'm sure somebody out there has much more experience and knowledge that I have and can lead me in the right direction.
Thanks for any and all help!!
Update...
So I went ahead and tried the hard reset first hoping that it might be a software issue. I am now at the screen that says "Tap screen to setup your Windows Mobile based device." No screen touches are being recognized. This seems to support my thoughts that there is a loose cable or bad connection. Agree?
I just slid the screen opened to see what would happen and it faded to white.
Yep, if my experience with the Wizard tells me anything, the flex cable from the main body of the phone to the screen is either loose or damaged somehow. Even a small nick or cut into the flex cable will cause it to stop working correctly. I would hunt up the Herald service manual and take your device apart and see what you can find.
Thanks ... I downloaded the service manual and plan on taking it apart. I have to make a run to the store though and buy a small enough Tork screw driver. T5 or T6 I believe.
Thanks again, I will post with my findings when I get going on it.
now what?
So ... I have the phone completely torn apart. I do not see any loose or damaged cables. It was dirty inside the phone but other than that everything looks just fine.
Does anybody have any advice as for things to look for, that might be causing this problem, while I have this thing torn apart?
Anyone else having a weird, intermittent issue with the touch screen seemingly not working right
IE: I try to scroll and instead it makes a tap where my finger lands. Unlocking the screen doesn't work 50% of the time because the lockscreen will just lag out and I have to sleep/re-wake the device
This happens on stock and after i rooted to tiamats rom

I haven't experienced or heard of this before, at least as you're explaining it.
Is this accompanied by screen dimming? Did this start after the update to HC3.2?

I use auto brightness, but I do not notice it changing during this happening
I got my XOOM with 3.2 on it
Your device may not be grounded. It's a common problem with touch screen devices. Does this happen when you're holding the device in your hands?

I really don't know, let me do some testing and see what circumstances it is replicated under.
How would grounding be determined? Its not charging...
I do have it in a silicon/rubber case. Would that be a problem?
Just for the sake of satisfying my curiosity - if you are experiencing this issue while your Xoom is docked - try placing your fingers on the back of your Xoom and typing with your thumbs.
I am trying to resolve a similar issue that I only encounter while my Xoom is docked at one place in the world - my work. Nowhere else does it do this.
I have installed a power conditioner, with no effect. It happens whenever the power is plugged into the dock. If I use an external power supply it goes away (batteries). I did switch off the florescent lighting and it is better, so it may be EM related. especially since it is a *capacitive* screen.
I have also read of people with other capacitive touch screen devices have the same issue when it is not held in their hands.
Let me know either way.
Thanks,
Frans

I have seen issue on gtab where some roms/kernel where having issue with screen calibration, there was a calibration files that could be created in the root with the name calibration.ini and upon reboot it was fixed, I do not know if this is valid for a xoom tho...
with a few rom I had NO issue whatsoever and never reused the calibration...

Well you bring an interesting point. The device was in my hands but I was not actually touching it... It had a rubber sleeve on it.
I since got the Motorola hard case which has some areas exposed and I also disabled the lock screen, and I have not been able to replicate the problem at all.
The device was docked at one point, charging, and the problem showed up aagin (recalling from memory). The fix was to power off the screen and re-wake the device. This did involve touching it, so...maybe its an electrical thing?

I had this problem with the stock 3.2 ROM. I haven't done any calibration, and don't think I need to: it works perfectly majority of the time.
I'll reenable the lockscreen and try to replicate it again.
Okay I think I'm onto the problem
I opened the case just now, still lock screen disabled, pressed just the power button and the touchscreen was acting up again.. couldn't slide to scroll, but could tap/point only
I then put my thumb on the side, as if naturally holding it without a case, and it started working normally again without any kind of power cycle.
Thoughts?
Have you dropped or jarred your Xoom a lot? Look for threads I started in this forum, I have one that explains this issue and includes a fix. My Xoom is still working flawlessly. I'd link it but pre-calculus is about to start.

I bought the XOOM second hand from someone who claimed they hardly used it. Right now sitting infront of me, the bottom right, on the back edge, there is a small pressured crease as if it was dropped (looks like the corner of my phone when i dropped it on tile).
I personally have not dropepd it, but I throw this thing onto my bed all the time, it fell out of the dock onto my hard desk once, so yeah its been knocked around.
Will doing that mod void the warranty?
I found no warranty stickers or screws when I disassembled it. The back cover is made to slide down so that Moto can do the 4G upgrade, so I doubt they want to be fooling with that type of thing anyways. I can't say for certain that sticking a piece of foam in the back of your Xoom won't void the warranty, but I can say that it fixes the issue(which also could be covered by warranty if you can get someone to believe you've got the issue, I however could not, so I had to take it upon myself).
Alright
I just ran into the problem again playing a game.. seemed like the right half of my screen just stopped working intermittently. Kept playing and it returned to normal.
I may pop it open and try the foam thing. I'm pretty good with disassembling laptops.. I can't see this being much harder.
Just wondering if anyone else is have this problem. My s pen starts writing from about half an inch from the screen which make sit hard to to write a neat note. A while back i downloaded a smemo.apk for 240 dpi and that when it seem to start doing it I have tried a full flash of stock rom but still doing it.
It happened to me too, Samsung said that it's because some S-pens have trouble on its sensor. You can ask Samsung to change S-pen for you, change until the problem is gone xD. That's what i do with mine.
Ok i thought it might be somethimg like that I ordered one from ebay the other day. thanks
try disabling auto rotation..
and choose again which dominant hand in pen setting..
if you used magnet case it would affect the s pen sensor too..
Your pen is bad, a few of these threads have poped up. With a working pen you can take your fingernail and push in the tip and it will work like yours is, from far, yours is just stuck in.
You can try and take it apart (there is a post around here with instructions) and reset the tip in the rubber grommet it sits in if returning it is a issue.
Touch Screen Tune
I use Touch Screen Tune (for Galaxy note) to fine tune the pen.
And it became much better.

The tip of your s-pen is pushed in and stuck, which makes the pen think you are pushing against the Note. Not sure how to get it unstuck, but that's definitely the issue. It's happened to a couple of people.

I also have the same problem..some guy posted a video on youtube as well..its a faulty spen...
Hi All.
Funny enough i have similar issue. My pen from time to time is oversensitive. I have been playing with it to check when and how does it happens. And i discovered that my spen has an allergy on me. I mean its me or my static charge is affecting it. Whenever i had such an issue i had to touch somethin metal or somebody to discharge myself. Or just put phone on the table. Whenever i broke circuit (i havent touch phone with both hands) or i disperse my charge spen started working again.
If you have such an issue try this out or even pass the phone to somebody else to check if the issue still stays with somebody else. I have been in touch with Samsung and they offered me a new spen so when it arrives i will check this out.
I got the same problem yesterday, i bring my note to SC and the customer service just laugh on me and told me may be my note is the new note 2 because it can hover
Anyway they replace it free of charge, thanks samsung
Oversensitive SPen means that a coil broke inside your pen, whice alterates the internal capacitance. Must be careful when carrying your pen, avoid drop it to the ground and so on...
I had an exam and removed the battery for my phone for the duration. When I put it back in, the bottom half of my screen stopped responding to touch. The screen itself is unharmed and uncracked. The S Pen still works flawlessly. However, the bottom half of the screen ("above" about 890 pixels on the Y axis) simply does not respond to normal touch. In addition, the volume buttons no longer change my notification volume. They still work for music volume, just not touch volume. When I long-press the power button, the power menu sits at the very top of the screen and has black covering the whole bottom of the screen for some reason. When I receive calls, the buttons are right at the top. Because of this, this seems to be some sort of software issue, but I have no idea what would cause it. Has anyone with more experience with Samsung devices seen this before? Multiple restarts and battery pulls have done nothing.
EDIT: In case anyone else encounters this, it had something to do with my case. I think my phone thought it was a smart cover for some reason. I enabled and disabled smart cover and then removed and replaced the case. It's working fine now.
EDIT: Never mind, that was a coincidence. The issue is DEFINITELY that the phone thinks it has a smart cover on it, but it has nothing to do with my own case.

I've had much the same problem. While the S-Pen was able to make selections that the touchscreen wouldn't, other S-Pen functions such as Air Command and being able to start an Action Memo wouldn't work. Waiting for an extended period of time (like 24 hours) and all of a sudden it started working again. However, while I was waiting, rebooting - even performing a factory reset - didn't' fix it! I just now rebooted it and it's not working again, and it's not in a case.
Where do you find the option to enable and disable Smart Cover? On the Note 2, it was (apparently) under Security / Device Administrators, but I don't find it there. The only option I could find was in Accessories / S View Cover / Automatic Unlock but changing this setting (including rebooting between settings) hasn't solved it.

Sadly, it was just coincidence that it randomly stopped happening when I enabled and disabled the auto-unlock feature with Smart Cover. My phone started doing it again and I've been unable to repair it. I went to Verizon and they wiped my phone before telling me I'll just have to get it replaced with a refurbished one. Very frustrated. Shame there aren't any AOSP based ROMs yet (like CyanogenMod)-- they'd probably fix it since the cover thing wouldn't be a feature.
Bump.
Anyone know of the APK which would handle S View Cover behavior? If we were to disable that I imagine the problem would go away. I'm still not totally sure of the origin of the issue, but it seems to come from a combination of hardware and software problems. The hardware sensor thinks I have the case on, so the software changes things around. When I call people, I get the S View Cover style call screen. If I change the toggle in accessory settings to automatically unlock the phone when opening the cover, hitting the lock button automatically unlocks the phone as though I had no lockscreen. However, when this is disabled, the lock screen is NOT in the S View Cover form-- it looks stock. This confuses me.
Any ideas from anyone else getting the issue?
Same experience
Just to add my experience as I go. This afternoon I received an error that my SMS data could not be downloaded. Upon sliding down the notifications I was unable to control much. I ripped the majority of my hair out over this.... My pen works flawlessly everywhere though. I eventually discovered it works fine on the bottom half as you described. I have to run to some appointments, but I'll touch back after I try a few things.

Maybe it was caused by the battery insertion or backplate replacement. Perhaps too much pressure or an uneven pressure damaged the circuitry, which is now loose and causing the intermittent error.
Or perhaps it was a static discharge from the battery.
Both cases seem to me to be warrenty items.

I thought the only thing necessary to unroot is to flash the stock ROM. The download is linked from the de la Vega post.

I have the same issue. I ve been trying to understand why this happened but no luck. I tried everything from updating to reseting. I first noticed it when i took the battery out as well. but the problem kinda fixed it self so i thought the phone has a spaz or something. but when i removed the battery again it happened again.
I took it to the people i bought it from and all they can say is cause there were a couple of scratches on the side of the case that it may not fall under warranty...
i was pretty angry cause its only two months old and the warranty is for a year. and the problem started happening while i was overseas so its been like that for almost a month. hopefully the sales guy is just talk cause its not up to him its just his "opinion" as he put it.
Did they explain to you why this happened? or if this is a common issue?
Hope your new phone is ok
I have this problem intermittently also. Exactly as described above.

any updates on this? im having the same problem now with my tmobile version. it fell facedown and the extended battery i had it in fell out. im going to try putting an aosp rom on it when i get home from work.
Timely post! I gave up. Verizon sending me a warranty replacement to arrive today.
Sent from my SM-N900V using Tapatalk
I have the solution!
Please. Let me know it worked for you, so people that doesn´t like to post and only read can solve this problem.
The Problem:
The half bottom screen is not working. Including the back button, the option button and the home buttom. they only work if you use the S Pen. Except for the home button. The volumes button do not work either. So the Solution is this..
take off the battery while the phone is on. YES, do not turn off the telephone and the take off the battery. Just take off the battery while the phone is on. It should work. I hope this is the solution.
One more thing. Do not allow your phone to dried up the battery completly so this wont happen again. It is better to turn it off before it dries up.!
Please let me know if it worked for you! I will let you know if this problems start again and if was only an coincidence.Hopes it not!
This tough me a good lesson! never buy a Phone from not trusted retailer, it is better to pay the full price a good store. The people that sold me the phone has a crappy warrraty like if the screen it cellphone is complete off they wont allow me to use the warranty and my phone had faulty battery conecction so it was off. then I paid 100 dollars to be repaired then this problem.
Ok, guys please let us know if it worked so people start saving their phone
Just happened to mine as well
Hard reset didn't work, on the phone with support trying to request a replacement now.
Finally Solved!
Hi
I had same problem
I did everything u said like:
mega wipe and changing rom
custom roms
taking out battery when it's on ( I Did this but I don't know It had any effects on my phone or not!)
taking out external card
But I still Had the Problem
Solution:
But I had a flip cover and I separated that from phone and thanks God,surprisingly It's Fixed and it works like a charm!!! after that I used my original cover and there is no problem till now.
Good Luck
Had the same problem of touch not working.
I tried everything as suggested by the members but my Note 3 is still not working right.Touch not responding all of a sudden in the bottom part of screen after i removed the battery for sim change. Please suggest something.

I haven't gone back to refresh my memory but it seems to me that all these occurrances were caused by removing the back cover. Try removing it and the battery and firmly press on every spot with your thumb. First place the device face down on table padded with a single layer of a blanket. Remove the SIM and SD card and firmly reinsert. Press the back cover on and try it, then return it for warranty if it is still bad.

I also was faced with this issue today at the start of my morning BUT I FOUND A SOLUTION
I have a Sprint Galaxy Note 3 N900P Stock ROM/ no root, no mods/custom kernels/boots etc...
My device side effects were
The bottom half of my screen was not responding to my fingers,
When you press the Power Button, The options appeared on the top section of the screen instead of being the center
When I press the volume up/down keys, The volume would raise and lower, But the screen that pops up and shows you the volume had increased or decreased didnt show up
Only way to use device was with S Pen
Basically all the issues everyone listed, I had them.
Now my solution; if the issue is a hardware issue.
After dissembling my phone to see what each hardware part of the phone controls, I've come to the conclusion that there was an issue with my USB Dock Connector section of the phone. I uploaded a image pointing which connector controls it. I tried to just wipe and clean it up a bit because mines had some residue on the underneath of it. Then I plugged it back in and it started back to work %100. After I tried restarting it a few times and shaking the device up, it still works; Although I am still going to order a replacement USB Charging Port with flex cable just in case.
fixed.
This is the definitely the hardware problem.
most likely happen if u ever dropped ur phone to the ground ----------- and reboot ur phone some what later time. (can be days or months).
Temp Solution to this problem is...
face down your phone to the flat floor or a table, gently hit the back, strong enough to shock the devide, but not that strong to crack your screen.
one other simple way is to drop your phone to the floor, screen is facing down, from about 30 cm high from the floor.
"simply, hit your device like you used to fix your ur old TV. "
that is just a temp. GL.
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.
