Ungrounded Screen Issue - Legend General

Is anyone facing the ungrounded screen issue on their Legend? For the uninitiated, just check youtube for 'ungrounded screen' (I'm new here. Unable to post links)
Repeating the same test myself, my screen isn't as responsive as it normally is though, not as bad as that video.

I've never seen that test but I was curious so I downloaded draw and tested it.
Top to bottom works fine for me no matter if I am holding it or it is placed on a surface ungrounded like the video.
I did notice a slight difference in left to right particularly in the top 1/4 of the screen. it starts drawing about 3mm in when 'ungrounded' and immediately when holding the device.
But honestly though, its designed to sit in the palm of your hand and be used with your thumb, or be held and operated with 2 hands. Is it a real big deal?

upper part is shaky when keyboard is opened. Normal?

The part where the display is becomes shaky a bit when you slide open the keyboard
Is that something that I should be concerned about or is it normal?
I think it's normal. I've examined four X1a's and they all had a small amount of play in the top part of the slider when open.
Mine has also a slight play to it (back and forth). Noticed this on the Raphael as well.
Keep in mind though, that the slider is only supported by two metal hooks situated (when keyboard out) at one end of the screen. So guess it's normal.
The play will also increase as the phone gets older (wear and tear). As long as the screen doesn't fall off I guess it's ok.
To prolong the life though, I try to be gentle when opening and support the screen when it's open (to reduce the wear and tear).
Mine's shaky when closed. Went to the service centre thrice and everytime they said it was normal.
Mine is a bit shaky as well. even when closed, but afer giving it some thought, i guess it impossible to make it totaly solid, at least with this form. i annoyes me, though. pressing the keys and you feel how it bends a little. when opened, I am afraid to press the little x or soething else on top of the screen, at least without supporting the lower side with my other hand.

I support it when open, cause it's impossible to make it solid (@least not in this form factor). It's easy enough for me though.. cause the phone fits in my palm so easy (and way easier than other phones I've had - But I do miss the tilting screen from Kaiser though..then again, that needed major support when tilted)
I am new to this board, hello everybody!
I have my X1 for a week now. On mine the top part is shaky when closed, it moves ~1mm up/down opposite of the slider hinges. Anyone else?
It annoys me, but I hope it is okay and won't get worse.
Greets and have Fun with Your X1s!
i think it's normal. I noticed that as soon as I took it out of the box and was very worried. it's my first slider phone and i didn't know what was normal and what was not. reading threads like this was very reassuring for me. I just hope it won't get loose, if it stays like that, then i'm happy.
It seems really solid to me. No movement at all unless I push on it. I’m guessing it will loosen up over time.
same here, closed and opened. When I press gently in opposite corners when closed, it waggles slightly. I got annoyed/worried about this after purchasing the phone few months ago and went to the store to ask about it. I got to test three different X1s and they were all similar, so it's not a problem (or at least it's by the design
A bit annoying still though, especially when using touchscreen with your fingers. Mostly when pressing on the right side of the screen (down-right being the worst), it waggles slightly under your fingers.
Same here too. About 1mm up and down when closed, and when open, same.
And yes Jent, it does waggle a bit. Try using the phone when you're lying in bed, and hold the phone upside down... every press will move the screen about 1mm and it gets annoying very quickly.
i also have the problem with the upper corner^^

Weird Touchscreen behavour - Video Doku.

Hi, I'm a big fan of the HD2 but in the last two weeks, since i own this device, i'm getting confused by some screen imput behavour that i will present you.
I want to figure out if this "screenbugs" i have to fight with every day, are normal or a hardwaredefect. To make you guys an imagine of what i mean, i uploaded some youtube videos for each bug.
1. The first one i call: The painting edge
This bug is only present if i not have installed the less sensitive CAB from this forum.
Explaination:
Many of you have notice that the glass of the screen doesn't fit exactly in the case of the device. The right bottom of the glass protrude a very little. Then i lightly press on this position, the screen notice a press on the right top...as you can see in notes on my youtube video:
Video 1: http://www.youtube.com/watch?v=c49x9vB4bzQ
------------------------------------------------------------------------
Beforce you say...my device doesn't having any of the following bugs, REMEMBER, This bugs are not present every second. Sometimes i can use the device for 30min without having some of this.
------------------------------------------------------------------------
2. The Electrocardiography
This bug, i think could be the reason for the following bugs.
Explaination: Trying to draw a straight line an you think you device will get a heart attack soon.
On the half of my second try you can see how the device suddenly works normal again.
Video: http://www.youtube.com/watch?v=t54m1dSLnV8
3. The shaking Screen
Explaination:
I have notice that some other guys have this bug too. You can see this on every scrollable screen, like opera, IE, zoomed pictures, the manila tab, startmenu...etc. etc.
Best seen on minute 0:54 in my video.
Video: http://www.youtube.com/watch?v=6hIE_wV4djs
4.The non pressed key
Explaination:
You are cofused about keyboard reaction while writing a text message? You type an "a" and getting a "t"? Than you have "the non pressed key" bug how i call it.
you have to watch on some key input where my finger is totally out of range. I don't mean the fault input next to the key i pressed...
Video: http://www.youtube.com/watch?v=_B1GiyMp_O4
----------------------------------------------------------------
There is a fifth bug i didn't get on video yet because it is very rarely.
I had have this bug only 5-6 times since i own this device, but it sucks realy hard.
I call it
5. The self-typing keyboard
Explaination:
Then i'm typing some text sometimes the keyboard begins to typing without having the finger one the touchscreen. it can be have a duration of 5-10 seconds or 20 letters/numbers.
It can also be watched, without keyboardaction. Then the screen scrolls wild in any direction without any finger on screen.
Video: http://www.youtube.com/watch?v=-fdXU8SoPTg from htcracer211
----------------------------------------------------------------
If someone can tell me if i can embed the youtube videos in this forum...
Go get a replacement, the screen is perfect. Although I admit it does not fit correctly but it is great. I only need the earpiece fix
please watch the videos before you comment anything...
...You're too much electrostatically charged...
...Or something of electrostatic is in the range of your device...
But it's like your touch panel is faulty. Get a replacement (warranty rules)
Have brought it back today...but couldn't get a replacement...no devices
tryed all your test and get no errors on screen, electro worked perfecly, keyboard keeps presing same key without leaving the range, and i cant notice any shaking effect.
So probably your screen is faulty , change your device as fast as you can matte
I have brought it already back, but it seems to be that others have all my listed bugs too. take a look at the poll results. On another forum a guy has tested the "painting edge" on 3 devices after he saw my video and all devices have this bug!!!!
Hey Guys,
I have the first 3 bugs on my HD2, too. But with BSB Tweaks 1.31 i solved the first 2 one by activating the option "Screen Sensitivity".
Hi,
If you look in the sticky thread here somewhere in the LEO section about tweaks and registry changes there is a topic on reducing the sensitivity of the screen.
I think what's happening here is the electric current in your fingers is playing havoc with the screen when your fingers are either close to or on the screen.
Let us know if this helps you.
WB
whow, that's a lot of problems for one device.
I have the "non pressed key issue" : (that's annoying as hell, typing a message is a heavy burden now) and the shakey screen. should i bring my handset back or try the tweaks... I didn't expect this from an 600€ handset

When i was made this video my finger was always with the same pressure on the touchscreen. It was not close...and not weak on screen...normal pressure. And you can see at the middle of my second try where i'm drawing lines in notes that the screen suddenly works normal.
I also wrote in my first thread, that this bug is not every second present...but then it's present its also the reason for some other input errors, like the "non pressed key" i think.
Quick question: How much pressure do you apply to the display (what is "normal"?)? Scince your display is reacting weird to pressure on the bottom right corner, any pressure might be linked to erroreous behavior. Do the shaking related errors remain when you don't press at allk?
to the OP: what ROM are you on ? have you tried 1.48 ?
I can recommende you to use screenprotector film and install cab for less sensitive.
But even without this all I had not this problem Looks like your sreen very sensitive for electrocharging and not have normal ground contact. This is way to warranty service.
lmao >.< sorry mate but get a replacement NOW!! I've never got these problems, everything works smooth and properly, sorry about that...
do u have a screen protector? i am wondering if the screen protector does anything bad to it...
You have the exact same problems I had when I first got my device, the main concern was the device having its own mind and making random key presses, even without you touching it or even being near it. I got my unit replaced and the new one works like a charm.
I noticed today that MY PERFECT SCREEN starting acting weird !!!! Its jittering !!! Damnnnn !!!!
I'm totally spooked by your video's!!!
I personally never experienced these bugs so I spend the last half our replicating your bugs.
The only thing I noticed was that Electrocardiography but I think you have your finger too flat on the screen (it has a too large surface area) because when I write on the screen as if my finger where a pencil (straight up instead of flat) the screen is working as it should!
I think you must have a faulty device. Perhaps try to flash it with 1.48 if you haven't done that already.

On iPhone with exactly the same finger it draws almost a precise straight line. This problem comes directly from HD2's screen, not from fingers, weather, humidity and so on.

[Q] Touch Screen Problems

Is anyone else having problems with their touch screen?
It will occasionally become unresponsive, and other times will just start 'clicking' repeatedly in random spots.
I find myself having to turn the power off and on (via the button, not a hard power cycle) to fix the issue. Its starting to get annoying.
Anyone else?
Yes, I am getting the same thing but I've found that if I just turn the screen off and then back on it fixes the problem. I don't need to reboot.
You think this would warrant an exchange? or is it just how its going to be?
I've put several hours on mine, but haven't experienced this issue. I don't know, if this happened to me more than once, I probably would exchange it.
It was happening to me all the time. I had to get a screen protector and haven't happened since.

Very good "solution" to what should be an obvious problem. The Nook Color has a *capacitive* touch-screen. If you get "junk/gunk" on the screen, it's gonna cause you issues. I find this to be the case while holding my NC and playing Flight Director for a while. The issue: My hands become sweaty and as a result of the slight film of sweat/oil on the screen, the NC's ability to measure the capacitive changes on the screen (and react appropriately to them) is compromised.
Keep your screen clean and you won't have this issue.
Note: after you wipe the screen down (damp cloth, etc), you will need to click the power button and go the lock screen and then back into the NC before it works right directly after cleaning the screen. The dampness of the cleaning cloth throws up the calibration enough to cause very strange things. My experience with "correcting" this issue tells me that in some way, the NC is recalibrating itself when you go to the lock screen.
johnopsec, this has been my experience as well. After cleaning the screen from finger-jam i don't get the phantom clicks. I also noticed that because I live in a very humid climate (Florida panhandle) there will be a thin moisture layer buildup sometimes and it really helps to wipe this off. I also have an incredible that does not have this problem but it has a screen protector which, I am guessing (and as gigadigit expressed), fixes the problem. Just make sure the screen is clean and dry before applying!
screen response
Also,
If you are holding the side of the case by the screen this throws off the touchscreen, I was having the issue where it would be clicking and multiple letter inputs when typing.
Also when it is laying flat and you have the power cord plugged in you may get multi letter inputs.
The trick, hold it by the back not the sides.
and if you have it plugged in and need to type don't leave it laying flat.
I have experienced this problem and loosely seen it correlated with moist fingers.
no moist fingers here and on my 2nd nc. this ones starting to have the ghost touches too.
My Nook Color started acting up after paying levels 3-4 to 3-6 of Angry Birds. I'm not sure if Angry Birds caused the issue or not as I haven't gotten it to do it in another app. I'm running 1.4.2. Doing a lock and unlock fixes the problem until it returns.
I managed to get Phone Tester to run after it got into this state. I made a video of it using a crappy webcam. There's a stuck finger in the corner.

Touch Screen issues while unit is plugged in..
It seems I have read on some forums that some people have screen issues.
Personally I didn't experience this until I tried to use my NC while plugged into it's wall charger.. It seems to act as if it has a grounding issue, which is not the case when the unit is unplugged.
So when you are running your multitouch or touch tests, do it without the unit plugged in..

I have had the same problem with my touch screen. I have the nexus live wallpaper and whenever you touch the screen it sends off the animation. Well sometimes it just goes non stop and sometimes opens up the window where you can apply a widget. I guess the most practical solution would be a screen protector but if not ill restore it and send it off to B&N
There's a small little app in the market named "Nook Screen Recalibrate" this app is super simple and easy to use. I hope this helps
https://market.android.com/details?id=com.assid.android.nookrecalibrate&feature=search_result
Here is the issue I have...
Right is the N button side. Just a reference point for this.
Reboot the Nook (I use CM7).
Bring up the keyboard
Touch Q in the center - you get W.
Touch Q on the right - you get W
Touch Q on the left - might get Q but you usually get W.
Recalibrate using the Nook Screen Calibration (above).
Q now gives Q unless you press on the right side of the key. I also notice I still have to hit the back arrow more to the left or I bring up the keyboard.
I've learned to live with it, but the left side of the touchscreen is slightly off and you have to touch to the left side of any object on the last 1".

yeah, for me it's the edge of the screen along the right side. it's less sensitive then the rest of the screen. I found that calibrating 2-3 times really works best.
There's also a fix in the nookwiki, but i can't get my adb to work on my laptop, I think its the drivers.
http://nookdevs.com/Recalibrate_the_NookColor_touch_screen
What is the left and right side?
I should have said that left is the side opposite the N button.
I downloaded Multi-Touch Screen from the market and I can see part of the problem is the angle of my finger. Straight on it's better.
Nook Color Touch Screen Problem
Having similar problem as described, after two years. Extended warranty expired ... two weeks ago (of course).
Tried cleaning screen, no help. Have not tried screen saver yet, but will.
In the meantime, I notice the comments about touching the sides, and I noted that as well.
Is it possible that this could be helped by opening it up and re-seating the case? Has anybody tried this?

Part of display nonresponsive to touch

I've had my Nexus 4 for a couple years I believe now, and overall it's been a nice device. I've had occasional issues now and then with software (Camera not available message, random powerdowns) but no hardware issues. A couple weeks ago, part of my display stopped responding. The LCD itself shows everything, there's no bars, no visible cracks in the screen. but the left hand side of the screen, I'd estimate about 1/5 the screen in width, no longer responded to touch. The far far left edge, along the very edge of the display, registered, and on the other side of that 1/5 worked fine. The area that was giving me issues was right about where the 'a' key on the keyboard is in portrait mode -- the only location I could press to get an 'a' registered an 's' as well.
This is all being tested with the developers Show Screen Touches and Show Pointer Information turned on.
Then, the end of this past week, it got worse. The entire left half of the display still shows fine, but almost never responds to touches -- maybe 1 in 100 times it will. Thankfully, I was able to get in one of those times and disable my screen lock. It seems to be able to register as far left as an x value ~418. This means the back button in portrait mode, for example, no longer works. To make me even more confused, it seems to register phantom presses. The device can be lying, powered on on my desk, no touching it, and the display starts showing screen touches -- the most common one I see is right about where the word Google is in portrait on the stock main screen. These will continue indefinitely.
All this to say, I suspect my digitizer has had a mechanical failure. Does that seem a reasonable conclusion to you? I like the four inch form factor of the device, and with most new smartphones getting larger and larger, I'm shying away from changing to another device. I've looked briefly at replacing the digitizer -- it seems you can purchase either the digitizer alone or with the LCD, and that when replacing just the digitizer it's easy to accidentally create problems with the existing LCD. Is that true?
Also, the part about having to use a hair dryer to pull the components apart makes me a little nervous. Screws and cables I can handle, but a hair dryer?

I would say it's most likely a hardware problem with the digitizer. The lcd/digitizer assembly is glued together so it's very difficult to separate the two without damaging the lcd.
Unless you have the tools to separate them properly, it's alot less headache to get the entire assembly already glued together.

Defective drawing board

Hello
I have just noticed that the a little area in the upper left corner around the ESC and 1 key, has very poor sensitivity. I almost can't draw there, it's like the sensitivity drops in that small area. Has anyone else experienced this?

Hi,
I have never noticed it before; but when I specifically searched for it, it is indeed there as you described. Sensitivity drops and cursor jiggles a bit.
I don't think this is much of an issue thou. Every drawing tablet I had had some kind of issues around edges. And, honestly, when you ever need to draw around edges? You simply move the canvas
Thanks
I suspected that this was a design flaw rather than a defect
I have the same problem and also there is a complete line with some important jitter when you draw slowly on it. I reproduced it on two different Windows Yoga Book, I did not have the opportunity to test it on Android.
Just went to the store where it's bought. I tested 2 Android versions, that was on display. And they acted in exactly the same way. So I think it's the way it's designed
Here is a picture of what happened if you draw lines with a rule. We can see a lot of jitter... Like if there is a line area that completely interfere with the pen. I also tried to follow the keyboard keys frames with the pen : it is obviously problematic in the corner we talked about.
Code:
https://drive.google.com/open?id=0B1Qu-HXdIAp0U0tvVWpRT016Tm8
This is a frigging design and hardware flaw. I had this issue with my previous YB as well. What were they thinking? It kills me. I want my money back. There are other areas with iesuse. pretty much upper %15 is full of issues, your lines might get wiggly!
It sounds like noone from Wacom or Lenovo tested these devices for real.
