EVO Video of touch Screen Working

We have seen multiple videos of the screen grounding issue and there are many that say theirs does not have this problem. I have two evo's and they both have this issue. I would request those who are not haveing this issue to please post a video of their phone's touch screen working while not grounded. It is not that I think anyone is lying, I just wonder if maybe the issue is not being tested correctly. I just want to see someone's that does not have this issue so I can be confident that if I return mine I have a chance of receiving one with out this problem. So please anyone that does not havethis issue show video of the phone on a pillow or bed or multiple ungrounded surfaces with the phone not plugged in to anything and demonstrate the drawing app and also the pull down notification so I can see one that works. Thanks in advance!

It's not consistent, I hadn't noticed it until after I found out...I noticed a screen tap wasn't registered when I clearly pressed.
If you look at the demo images, it shows it does work, but doesn't always work...it's not consistent like it should be.

Yes I know that it is inconsistant... that is the issue. What I am asking for is to see someone's that consistently works while not grounded. I want to see if there is even one evo out there that has a touch screen that works as it should while not grounded. I believe that possibly those that say they dont have this screen issue may not understand what we are saying or are testing it differently.

mines having the issue hold it in my hand its fine lay it on the desk it messes up

I had never noticed this until I did as you suggested and use it on my pillow and sure enough I have the same issue. Not sure if it matters or not to me yet since I only notice it during this testing and not with every day use. Guess I will have to think about it!

Just tried this out on a pillow and for me it is just the top 1/3 of the screen that goes unresponsive. Tried it with the marketplace and i could scroll just fine through the list of apps at the bottom but from the Apps, Games, Downloads Tabs up, the screen is unresponsive.

I returned my first Evo because the screen in the portrait notification bar area was dead to touch.
My new unit has no issues whether lying flat on a desk or on a bed or pillow.

Mine is going back to Sprint a new one issued, just waiting for them to get the new batch in.
I called them yesterday about it and let them know it is being returned for a new one.

Do you have a video of this?
Up until just now I thought mine was perfectly fine but I just tried setting it on a pillow and doing it and lo and behold, it's a little glitchy at the top 3rd of the screen. It's perfectly fine laying flat on a disk or stack of papers though.
This doesn't seem like such an issue to me though. Not as much as the 30fps issue. When am I ever going to be lying my phone on a pillow using it? I always hold it in my hand anyway.

If the original poster wants to keep a tally: I have the problem and have the 1st hardware revision. I also confirm grounding the screen itself did no fix the issue (since I have the invisible shield). However, the problem was immediately resolved when I grounded the battery/phone negative terminal by running a wire from it to my bare finger. Touching the screen with my other hand/finger showed the issue had disappeared.
I posted a video on YouTube, but xda won't let me post links since I am unverified.

So I am coming to the conclusion that this grounding issue effects all evo's, seeing that not one person can produce a video of it working otherwise.

My evo works fine no matter what its on. I post a video later today.

Works
Mine works. I haven't seen an issue on any surface or lack of surface. The four other's I know who have the phone haven't had this issue either.

Mine works too, no grounding issues here. Why no video? Just don't feel the need to prove anything to you.

My EVO doesn't have this problem at all. I put it on a stryofoam plate and it was slightly less responsive, but still worked on all parts of the screen.

Mine doesn't have the screen grounding issues, but my colleague's does. I used the phones side by side and I see how the top 1/3 of his screen doesn't respond when laying flat. Mine works perfectly. Unfortunately I have bad light leakage above the buttons where his doesn't.

No video necessary. Just do what I outlay in my post:

Takes only a few minutes and you can see immediately and with real accuracy whether or not your phone is working properly.

I am asking for video simply to see if there are any phones out their that do not have this issue. If u don't want to help a fellow evo enthusiast out fine, but seeing how I have not seen a single video of the phone on an ungrounded surface which does not suffer from this issue j doubt you are testing yours the same way if it is not giving you the same result. That
Is why a video would be helpful. Because if yours indeed does not suffer from the problem then that means that there is chance that if I returned mine that I could get a working model. So if you want to help fellow forum members out... post a video.

Does anybody in here ever USE the kickstand?

Screen sticking

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?

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.

[Q] Screen Repair - only backlight works (can't pinpoint the problem)

Mods, sorry if I should've posted this in another sub-forum. Just getting to this quickly as I've gotta head out, but would like to know/get any advice on what to do.
My T-Mo G2 just stopped displaying data on the screen one day, but the backlight still worked. It wasn't dropped at the time it stopped working (it was dropped previously, but was inside an Otterbox Commuter case at the time... thought that may not be saying much). At the time this happened, I was working outdoors, had the phone in my pocket, and was sweating while doing somewhat heavy lifting. When I attempted to use my phone, I noticed that only the backlight would turn on when I powered it on.
I could still answer calls by using the touchscreen slide-to-answer thing (purely by memory), so I know that component works. Sliding the keyboard open did nothing.
I disassembled the phone to check for any components that could've gotten twisted, burned out etc..., but this didn't appear to be the case. Any ideas?
I've attached a video on what happens when I power on my device. Any advice would help. Replacing the LCD seems to be the cheapest fix, but I don't want to buy one and realise it could be something else. Thanks!

[Q] Upside down screen rotation problem

I'm sorry if there already is post about this problem, but i couldn't find anything useful so i decided to ask for myself.
The other day i bought a second hand i9505, the problem is that the screen rotates upside down. When i start any app and turn the phone sideways the screen rotates exactly 180 degrees from what it's supposed to be, which is very annoying when watching a youtube clip or taking a photo. The phone was on stock 4.4, at first i thought it was a callibration problem so i installed a stock 4.2.2, but no luck. Then i installed slimrom but still no go, tried different kernels (like 4 or 5) and still nothing.
So my question is is there any way to fix this without taking it to the shop? Like a patch or an app to fix it, and how can i see the values of the gyroscope to see if it is outputting what it's supposed to ?

As you have tried several different ROM's, presumably the error is hardware related. As you bought it as second hand, I'd bet that it was reason of sale (mechanically caused sensor(s) damages are not covered by warranty).
sorry that I could not provide more optimistic assessment.

I figured as much, but thanks anyway. So there is no app to flip the rotation ( invert it so that it is normal ) ?

[Q](cm11) phone app freezes, screen becomes unresponsive

Hi all,
Im at a loss here, I dont know how to move forward with this problem so im asking for help lol XD.
I just gave my nexus 4 to my gf ( just got my opo last week). The phone was running cyanogen mod 11 ( some nightly version between m6 and m7).
So when my phone came in the mail, I dropped her sim in my nexus 4 (witch was working perfectly) and after making a phone call with it, she tells me she thinks the phone app is broken or something...
So I have a look at it and this is what its doing now. When I call someone, as soon as you click call the screen goes black. To bring back the screen you need to click twice on the sleep/wake button on the side ( kinda like if you were closing the phone and re-opening it) just for the screen to show again but none of the buttons work. Well none of the phone app buttons work, I can still click back/home/previous app buttons or slide down the top menu just fine. just cant click any of the number keys, hang up, hit speaker phone or anything related to the phone app. So in order to hang up I have to click home and then use the drop down menu and click hang up under the phone notification.
Before droping her sim card in the phone I did a standard wipe/factory reset on the phone just to give her a clean platform. So since that was already done I've tried updating to a stable ( M9 in this case) release, problem is still there, so I tried to wipe dalvik, cache and done a data wipe/factory reset from the CWM recovery and flashed a fresh cm 11 M9 with gapps and I still have the problem.
Im at a loss at where to begin looking for a fix for this situation, I've looked on the xda and cm forums and ran plenty of google searches for this problem but im coming up empty ...
any help would be greatly appreciated,
regards
Chris
Edit: omg screen protector was interfering with the proximity sensor... Is this a common problem with nexus 4 or could this provblem still be related to my hardware/software ?
(I've never used a screen protector before).

If the screen protector isn't applied carefully, it might interfere easily with the sensors. If you want to check, then download a sensor tester from the play store, and use it to see if the sensor is working without any protector over it.

haha thanks for your reply, I've been trying to solve this issue for a week, been looking on the cm nightly and stable forums and here on xda trough all the posts that sounded closely related to my problem and didn't find anything... as soon as I post a questions 3 minutes later I found the problem.
To test it, I simply peeled the screen protector off and held it there while I made a call and it worked perfectly !! Then I cut out the part that goes over the prox sensor and its perfect again ( looks like crap but works ). Still gonna download that sensor tester ( curiosity XD).
P.S: totally unrelated to this post, I've been reading some of your "how to" posts here on xda, just wanted to say thanks for all the info you have put out there XD.

Hehe No problem

This happened with my co-worker's Nexus 4 (which is now my Nexus 4). She had been complaining about this for like a month, until I actually saw her screen, and that the corner of her screen protector had flapped loose and had a bunch of crud built up underneath it. It was a forehead smacker for me when I realized how obvious the cause/solution was. Not so obvious when I took possession and replaced the screen and had the same problem.
