Have any of you guys temp rooted? I have. I don't know if that is the issue since temp root attacks the graphics driver to get root.
[HTC EVO 3D] dcfella:
Bone stock here. The problem comes and goes randomly. Had the problem half hour ago, just left it alone for awhile, and now it seems to be normal again.
[HTC EVO 3D] Irishman42:
I've never thought I had very good luck, but when I come to these forums and read the problems so many of you guys have with your phones, I think I do. I've never had an issue with any of my Android phones. I wonder if its because I hardly download any apps. I mainly use it for browsing the net, text and phone calls. Just weird.
[HTC EVO 3D] dcfella:
Any of you guys with this problem notice that it happens more when attached to USB? I just realized that the past 2 or 3 times I have the touchscreen issue that I also had the 3D charging on via USB on my computer.
[HTC EVO 3D] -viperboy-:
Yeah, seems like most phones act weird when plugged in. Still having lockscreen issues, really REALLY annoying!
[HTC EVO 3D] rmonty:
Mine has been having a ton of issues starting this last weekend. Sometimes it seems to have a mind of it's own and keys just start getting pressed. Other times it won't process touches. Most of the time the App drawer and personalization launchers at the bottom of the sense skin won't work. Thought I had it fixed last night by clearing a bunch of program data, but came back today. Seems to be a hardware issue. Probably take it back in. Really upset as this is my third one so far. Have done multiple hard resets to try to clear it.
[HTC EVO 3D] maejrep:
I was able to catch this happening in the "MultiTouch Visualizer" app, and took some screenshots of it. These screenshots show what appears to be 2 separate issues, but they seem to be closely related.

In this one, I'm actually touching in the center of the two touch points (i.e., where the blue circle appears), but there it seems to have some kind of "gap" in the sensor, where it thinks that my one touch is actually two. It always occurs at that horizontal location -- basically along the blue horizontal line.

If I move my finger up, it goes back to one pointer:

and likewise if I drag down, below that problem region:

But when crossing that region of the touchscreen, it gets interrupted and thinks there are 2 touch events. That's what makes it difficult or impossible to unlock when the problem is occurring.

The 2nd issue is that after a while of testing, it actually ended up "sticking" where it was registering two touch events at the bottom center, even though I am not touching the screen:

and this is what happened when I did touch the screen (pointer "1" is where I was actually touching, but pointers 2 and 3 were still registering, so it thought I was touching the screen in 3 places):

The problems seem to come up about 2 or 3 times a day. Usually at the worst possible moment -- there was one time I was trying to snooze the alarm, and somehow it ended up tapping that center location on its own several times... First tap opened the Phone app (the center button on the Sense home screen) to the call log. Second tap registered on the green "Call" button, so it ended up redialing the last number I called. I panicked and tried to end the call by tapping several times on the End Call button, but it wouldn't register at all... I tried home, back, opening the notification bar, etc, and nothing was responding. Eventually the call ended after going to their voicemail, but then it tapped the green "Call" button again, and called them again!

I'm probably going to have the same issue trying to replace it, because it doesn't happen all the time. :(
[HTC EVO 3D] phatmanxxl:
I've had this issue I can recreate it, I returned my first 3d and noticed the second one did the same thing. I think its a kernel issue because the cooked kernels don't have this problem. And this seems to happen after rooting the phone using the temp root method.

It has something to do with the multi touch.

Ill take the draw app, draw a line and at the same time touch a different part of the screen, the line im drawing will now look like this __ __ __ __ all broken like that. This has happened on two 3d's now. So when your keyboard is suddenly becomes non responsive, this is probably what's going on. The problem will fix itself in about five seconds or so and operate normally again. I thought about making a video of it.
[HTC EVO 3D] phatmanxxl:
I made a cool YouTube video of the problem:

http://www.youtube.com/watch?v=8rz3uWFuDkI
[HTC EVO 3D] el_chamuco:
i was watching that video and i was gonna paste the link lol
[HTC EVO 3D] ogrillion:
I had this exact thing happen to me yesterday. It called someone I really didn't want to talk to, and I kept trying to hang the freakin phone up. It went to their voice mail and I am yelling at the phone to shut off at this point, and I finally just ripped the battery out... Probably was a funny voicemail for the person.. ugh..

I get touchscreen issues but it only seems to be when I just washed my hands and they are still ever so slightly wet. Thats when the screen gets super stuck and I have all sorts of issues. And I would never use my phone with "wet" hands, this is like after I used a paper towel and I didn't even think they were wet, wet lol..

It happens often enough to be annoying, but not so often that each time it does it I am still confused as to wtf is going on.
[HTC EVO 3D] atistang:
Mine has had random times where most of the touch screen wont work since day one, happens every couple of days, usually have to reboot for it to work again
[HTC EVO 3D] seraph863:
This started happening to me, too on the very first day I got the Evo (Release day). It usually started right after watching a video from YouTube.

Now running Synergy Nightly 240 and getting screen problems, too. I'm not sure if it's an isolated case, but I can move the homescreen and open Messages, but I can't open any messages or create a new one. I had to shut the phone off and back on before it would work again.
[HTC EVO 3D] mikeyxda:
I repeated this using draw, sometimes tapping the upper left corner while moving my right finger around. Smooth as butter. No skipping. I use multi-touch paint too: no problem with that either: can draw simultaneously with two fingers.

I'm rooted, but on the stock ROM.

Edit: I notice you have a finger on/near the headset port. Wonder if it could somehow be getting headset (control signal) "noise". Does it still do this if you don't hold the phone with your left hand?

Mike
[HTC EVO 3D] phatmanxxl:
It does it anywhere when I lift my finger while touching the screen in another spot. It only does this with the stock HTC kernel. The phone was replaced and the replacement did the same thing. I doubt two new phones in a row are faulty like this. Im convinced its a kernel issue having to do with root.

I should have added to the video showing the kernel versions doing the same motions to prove my point.
[HTC EVO 3D] Visionikz03:
I posted about this the other day! I requested a replacement. Well see how the new one goes. Very annoying when u cant hang up a call or hit a button on the keypad during a call!
[HTC EVO 3D] mikeyxda:
Doesn't fly with what I'm seeing though. I have the stock HTC kernel (and stock HTC ROM) with s-off/root. No problems at all and I can't repeat the problem outlined in the YouTube video. Tried many times: mine never skips. Maybe it's some combo of installed/running software? I do have a lot of bloat frozen. Lemme check my wife's non-rooted 3vo... Nope. Tried hers using Draw and hers is fine too. Tried drawing and tapping all over the screen with another finger at the same time. No issues. And hers is completely stock: never even seen root.

Mike
[HTC EVO 3D] rmonty:
Thanks for the multitouch visualizer app. Now I can demo it pretty easily. It shows multitouches even though I only have one finger touching. All I have to do is drag my finger up to where the clock is. Then at times it will show the one large touch right where the phone launcher and call button is, thus causing the annoying self calling "feature".

I did notice it seems to happen regularly right after I do a sync all under the Accounts & sync. I have exchange, Facebook, Google, HTC Sense, Skype, Twitter, and Weather syncing.

Not sure if it was just a coincidence though.

I'm going to record it when I get home tonight to prove to Sprint/HTC I am not crazy.

Edit: BTW, I am running stock, no root.
[HTC EVO 3D] saltorio:
Does it tend to happen after the sync is complete, or while it's happening?

I ask because I found on my old X10 when the phone was syncing the system would intermittently be unresponsive for short moments, but would remember all touches, and then apply them all at once when the system caught up.

With the EVO 3D being dual-core, this should be less of an issue (if at all), but it may be a factor.
[HTC EVO 3D] dteze88:
Hi everyone,

Are any of you using Widget Locker? For some reason that app gives me multi touch problems installed. When I uninstall it it comes back to being perfect. I narrowed it down after installing each app at a time. Just a thought, good luck. :)
[HTC EVO 3D] rmonty:
It happens after sync is complete.

Widget Locker is not installed.

Edit: Another interesting find is now I know why the touchscreen seems like it has locked up. It actually is processing a phantom touch, so another touch doesn't register correctly.

Edit2: Did a reboot with sync disabled and it still has the issue. Probably not a sync issue and just a coincidence.
[HTC EVO 3D] antiphon:
This seems to have fixed it for me:

Edit: Sorry, wrong thread linked. I can't seem to find the original post, but there is an app called Touchscreen Booster in the Market. It's designed for the SGS, but works for other devices too. Set it to Super Optimized and Sensitivity to 0.
[HTC EVO 3D] demo27vol1:
Can anybody confirm this? A simple battery pull gets rid of the issues for me..at least for a while. I would like to use this if the issues come back.
[HTC EVO 3D] antiphon:

This seems to have fixed it for me also. Will keep testing. Thanks!

Edit: Nevermind, started doing it again. Arrrrrgh!
[HTC EVO 3D] phatmanxxl:
I think it helps.
[HTC EVO 3D] maejrep:
Possibly a separate issue, but this is not related to where I'm touching/holding the phone when it happens to me -- when I was taking those screenshots in DDMS, the phone was sitting on my desk, I wasn't holding it.

I've also thought about possibly something to do with moisture, because at first I was noticing it happen a lot when it was very hot and humid out. But I've seen it happen even inside in A/C. I tried wiping the screen on my shirt or something, to see if it was some kind of residue on the screen causing it, and usually that doesn't change anything... I just put it back in my pocket for a few minutes and it's usually resolved by the time I go back to it.

Right, from my post on page 2, mine seems to be two separate, but possibly related issues: one where it has some horizontal line (see the blue line from Multitouch Visualizer in my screenshots), where it won't register a smooth motion across that blue line. Almost like it's a dead strip in the touchscreen sensor, so when I'm actually *on* the line, it thinks I'm pressing twice (just above and just below the line) -- that makes it impossible to unlock because I can't drag the ring up across that line.

The other issue is where it registers two "phantom" touch events at the bottom center, so anywhere else I try to touch actually registers as a 3rd pointer. In some cases, this causes it to, e.g., assume I'm trying to pinch/zoom when I really only have one finger on the screen.

Hard to say if it's a kernel issue though, I haven't started trying a custom kernel yet to add some debug data to the driver. Since it's intermittent, I'm leaning more towards a hardware issue (like a loose connection somewhere). But a loose connection like that would be far less likely to be this widespread, I would think... And seeing all the responses in this thread, I'm thinking it's fairly widespread. Dunno, maybe this weekend I'll get around to building a kernel and see what happens.
[HTC EVO 3D] xHausx:
The past couple of days I've started noticing this a lot as well, the bottom of the screen is responsive but about half way up it stops responding to taps. If you drag your finger up from the bottom it follows you though so that makes me think it's something with the software.

I remember seeing many people with Sensations complaining about the exact same thing so it's not just us.
[HTC EVO 3D] z50king:
I bought a few 99 cent usb cables from China and one of them made the screen act weird when plugged in with it. Only the one cable though.

Seller gave me refund for it
[HTC EVO 3D] rmonty:
Finally decided to go back to Sprint store and they are getting me a replacement. Mine has started becoming unusable where I have a hard time even answering the phone due to it registering a touch when there really isn't one. Hopefully the new one won't give me problems. Keeping my fingers crossed.
[HTC EVO 3D] SpyFi:
Hmm

May be a bad digitizer or... If you are plugging your phone into a non-standard charger like a car charger or other phone charger with same plug it may cause this issue. Finally I would go to settings and Calibrate your touch screen. Calibration will help tell the device how you use it and where everything should be . Good luck!
[HTC EVO 3D] uofajac:
I am also having touchscreen issues. I temp rooted, then went s-off just last week. I started experiencing after a couple temp roots.

I have returned to s-on andd rerooted twice already. The problem seems to go away for a couple of days and then it comes back suddenly without warning. I went to Sprint on Friday and of course it was running silky smooth when I took it in. They looked at me like I was a retard. The stupid sprint rep decided to give me a tutorial on how to use the phone. I felt like kicking him in the nuts.

I'm going to return my phone back to stock s-on and wait for the problem to come back. Then hopefully I can get to the store in time to show them. It sounds like this is a widespread issue. This sucks. I'm gonna be pissed if I have to switch to the SGII or the Photon.
[HTC EVO 3D] uofajac:
Just did a complete factory reset from the bootloader and returned to s-on running the stock RUU. 3VO is purring like a kitten for now. We'll see how long this lasts. I'm hoping to reproduce the problem soon. I don't want to be stuck with a non-rooted phone for long.
[HTC EVO 3D] apols:
I have this exact same problem but outside of the return period. I'm getting absolutely sick of the bugs with this phone. I'm still stock (waiting on cyanogen), but if this is a hardware issue, I'm going to try and force sprint to replace the phone. Any idea if software changes can fix this?
[HTC EVO 3D] rmonty:
Lucky for me, the phone started doing it's thing right when the Sprint rep picked up the phone. They stated "that's annoying" and proceeded with the replacement. New one is working great <crossing fingers>. Mine seemed very much like a hardware issue as I could squeeze the phone in a certain area and it would start acting up.

Ryan
[HTC EVO 3D] maejrep:
Ryan, what area of the screen were you having problems with, and where did you squeeze to get it to act up?

Wondering if everyone having the issue is seeing exactly the same symptoms and characteristics, or if it's slightly random. If everyone sees exactly the same thing as the screenshots I posted in page 2, then that would suggest it's software related (some bug in the kernel touchscreen driver). But if it's only similar symptoms, with different characteristics (ie, mine won't let me drag past about a half-inch from the bottom of the screen, and the 2 phantom touches appear at the same area in the bottom-center ... but someone else mentioned it stops tracking about halfway up the screen, so a different section of the screen), then that seems very much like a bad batch of screens, making it a hardware issue.

Has anyone else having this problem tried the touschscreen teardown mentioned in another thread in this forum? Wondering if just a teardown and checking connections might fix the issue.

I really hate living with a broken phone, it's just such a pain in the ass to take it in, since it might not be showing the problem at the time I take it in, and then I have to prove my case to an idiot. Would much rather just have Sprint send me a new one and let me send the old one back... or fix it myself.

fwiw, I tried the Touchscreen Booster app also, and it seemed like it might have helped a little bit, but it certainly didn't make it go away completely.

I've seen other people mention calibration as well... But what kind of calibration are you talking about? I saw no place in settings that would allow calibrating the touchscreen. In fact, I get the feeling that the people who are suggesting calibration are just pulling out buzzwords? Cause if memory serves me correctly, capacitive touchscreens do not require calibration, and therefore they do not provide a way to perform calibration. Calibration is a requirement of resistive touchscreens. I'd love to be proved wrong though, just give everyone clear instructions for how to get to this touchscreen calibration that you're talking about.
[HTC EVO 3D] phatmanxxl:
The calibration is somewhere in the keyboard settings, I can't confirm cause I deleted them all since I use smart keyboard.
[HTC EVO 3D] maejrep:
Yeah, I thought someone might mention that... That is not a touchscreen calibration. That's to calibrate the HTC "Touch Input" keyboard only. It does not affect the rest of the touchscreen, and if you're currently experiencing the problem (like I just was when I went through it), this "calibration" is worthless, because the bottom row of keys is untouchable... Each letter that's on the bottom row required 2 or more attempts to touch, and more than likely, it registered my touch in the wrong place, thereby calibrating the keyboard to work around the problem area, but not fixing the touchscreen at all.

This is not a calibration area, it's the touchscreen failing to register touches in a certain area, or incorrectly detecting a phantom touch in that same area. It's like scar tissue with dead nerve endings ... it just doesn't know that you're touching it there :) And the dead strip is wide enough that the kernel touchscreen driver cannot report the touch as continuous when a swipe "jumps" across the dead area -- so the only way it knows to report that kind of jump is by reporting two touches (one below and one above). It might be possible to work around it with a custom kernel driver, to be more tolerant of that "jump", so that the swipe can be continuous, or so that two touches that close together can instead be reported as a single touch in the center. That would fix (workaround) the dead area, but still wouldn't fix the phantom touch events I've seen.
[HTC EVO 3D] DJ1994:
I had this happen. Just get a new one. It's the only fix.

Edit: the way mine happened was the spot where the e button is went dead. Really the only way to fix it is to replace it. I've had my current 3vo for a month and a half with no problems.

boom!! from my shooter
[HTC EVO 3D] charnsingh_online:
Same Here Annoying, Stickin n randomly not able to draw pattern
[HTC EVO 3D] rmonty:
It was up around the power button and the battery indicator. If I put a little pressure on the screen in that area, it would normally cause the phantom touches at the bottom. Every once in a while the bottom of the screen would not register touches either, didn't know how to recreate that problem.

The new one is working fine so far and have not had any issues. This is my 4th one, and I loathe having to take them back.

First one had dead pixels after about 4 days, 2nd one did the continous rebooting you have probably read about, 3rd one had touch screen issues. I really hope I got lucky on this 4th one.
[HTC EVO 3D] apols:
Mine happens almost exactly in the middle of the screen, which is unfortunate because many important menu buttons pop up there. If I go to click them, it registers a press with either the one above or below. I went to sprint, who offered me a replacement for 35. I told them I didn't feel as though I should have to pay for defective hardware, considering there was no damage.

Any idea if the replacement hardware is actually a brand new, in the box? they said it would have to be shipped from a warehouse and would take a few days.. I would guess that if it were a new, retail box, they would have them in the store already..

Coming from a nexus.. this has been a very disappointing experience.
[HTC EVO 3D] maejrep:
Yeah, usually replacement devices are refurbs. That's been my experience with most companies. To them it's more justifiable to repurpose a refurbished device to replace a defective one, since it's basically like them doing a full repair of your defective device.

Also, if this is just a bad batch of digitizers, a refurb is probably less likely to have random problems like these, since someone has to actually take time working on the device to repair/refurbish it, so would be more likely to catch something like that. In a box, it's basically coming off an assembly line.

I'll probably just take it in this weekend, and hope that it's acting up when I show it to them. Does anyone know if they'll try to repair it right there, or if they'll just replace the device? Would it be replaced/repaired same day, or more likely to have to keep the phone for a couple days, or have to order a replacement and wait for it to be shipped? I've been paying for TEP for several years, and there's no physical damage, so it shouldn't be an issue.
[HTC EVO 3D] calchung:
I seem to know the problem. This happens when the touchscreen is wet, and it thinks that it is being multi touched (as shown in Phone Tester) if there is water or sweat on the screen. I have done a little experiment and that is exactly the problem.

I am try to make a youtube video.....please try if your evo has this issue.

[HTC EVO 3D] chefdave12118:
My phone has been going wild for a while now.... Phantom touches when I'm playing music and not near the phone, phantom touches when I'm using it, pull down menu has major lag, etc. I just assumed it was a kernel or ROM issue. I haven't flashed a new ROM or kernel since the beginning if August so i assume its bugs with the new ROM that hadn't been ironed out. Maybe it is the hardware.
[HTC EVO 3D] who's high pitch:
Newbie here, I would first like to thank you all for trying to find an answer to this annoying problem. I can second the wetness/moisture/sweat reason that calchung cited. (Thanks for the vid!!)

When the touchscreen issues happen to you all, feel your hands and check if they are sweaty even in the least. I have found that just a little bit of sweat on my fingers will render the screen useless for at least a minute. I can't even see the sweat on the screen and even wiping it down with a microfiber cloth will not make the "ghost-touches" go away. The only solution that I have found is letting the phone sit for about a minute. After the minute, I'll activate the screen and I'll know that the ghost-touches are gone because the unlock ring (I'm still all stock) will no longer be bouncing around.

Point being, I doubt a new 3D will resolve anyone's issue. I could be wrong, but every time this happens to me, my hands are somewhat sweaty. I'll bet that is the case for some of you as well. And it may just be something that we all will have to live with if we want to keep this very good (in almost every other aspect) and powerful phone.

Full disclosure: I am using a cheap screen protector, which may be exacerbating/minimizing the issue.
