[Q] Touch screen acting weird - EVO 4G Q&A, Help & Troubleshooting

When I press on the very bottom of the screen (edge of the glass), it acts as a click to about 1/3 the way up the screen. This is annoying by its self (and doesn't seem ROM related) but also my screen sometimes locks up, with a point at about 1/3 the way up the screen, and horizontally in the middle, and I can't do anything until I lock the screen and leave it off for a second. More recently, but related to this issue, the keyboard when typing hasn't been accurate. I've tried to type 'a' but got caps or 'q' instead, and I get letters I didn't press.
This is not ROM related, as it started happening on CM6 about a week ago, and I've flashed Ava V9, Myn's 2.2, FrEaKy Evo, and CM6, and I have tried stock kernels, and Kings. It seems to lock up more when plugged in also. I've been watching the forums and I haven't seen anyone else post about this, is it just me? It seems very hardware related, but if there is a fix for it that someone knows about, please let me know.
If I get around to it I might take a video of what I'm talking about, but probably only if it's requested.
I'm currently running Myn's Two-Point-Two with King's CFS #11 and am still getting the issues. I've rebooted, and wiped cache/dalvik, flashed new roms, reflashed, nothing.

I am having the exact problem, except that the spot that keeps getting phantom clicks is at the very top of the screen, so the drop down bar starts freaking out. I downloaded the program 'dotty' and it is showing that a touch is being registered in the expect spot, so I'm pretty sure it is just an issue with the screen hardware. I want to take it to a sprint store and see if they can replace just the screen instead of getting a brand new phone because I have so much stuff downloaded on it and I don't want to lose data/settings.
It happens a lot, but then I will have days at a time that it stops happening...its just very strange.
Its good to hear that I'm not the only one with this problem. Currently running rooted stock froyo. unrevoked forever. Original June 7th release device.

same here...was happening witht he W/q as well...but when your viewing a white page you can see a light on the screen brighter than the rest...

W/q? what are you talking about there?
also the light bright spot is completely unrelated: evo developing a light spot in middle of screen
Screen burn possibly due to overclock
Bright spot in the lower right of screen

I downloaded dotty, and it's saying my spot is at:
X: 159.6
Y: 363.5
and P which I'm assuming is the size of the area being touched at .937.
I tested P and it does seem to be how big of an area you're touching but the biggest that I could get using my thumb was only .235, so it's a huge area and constantly in the same spot. Some times it gives me two points or one a bit up and to the left.

"Ghost inputing" problem.

I'm a first time poster. I have searched the Q&A section a few number of pages about my problem and I can't find anything.
My phone likes to press a certain area of the touch screen without me touching it at all. I don't really know what else to call it except "ghost inputing". Sometimes when I go to input text or when I'm at the home screen, it decides to go crazy. If I'm typing up a text message, if in portrait, my phone likes to type Q's even when I definitely don't want to. If I'm in landscape, a bunch of spaces and period is what it likes to press. If I'm at the home screen, the phone likes to pick up an app or open it.
It gets pretty annoying, especially when I'm just trying to reply to someones message. My only temporary way of fixing it was to turn on and off the screen. Sometimes it takes awhile.
I have tried flashing a stock 1.47 ota rom but it didn't really help, actually made it worse. Touch screen responsiveness dropped significantly, so i flashed back down to like 1.32 (responsiveness came back).
I got my phone the day it was released, so I don't even know if I can bring it back to Best Buy or not. Any kind of suggestion would be great... this problem can really bring my spirits down sometimes, especially when I'm showing off my phone to random people when they ask me. Kinda embarrassing to have my phone freak out when it's supposed to be a high end device....
Sounds like a warranty thing. I'd hit up htc.
Sent from my EVO from the Apple Store.
Im having the same problem making my phone useless :/
I have been trying to bring this issue to light for sometime!!
I have a topic on it already if you guys want to add to it but the end result for me right now is trying to get the phone exchanged..

I have had the same problem.
Turning the screen on and off sometimes makes it go away. It seems like it started when I rooted (simple 3 click). Not positive about that though.
I'm now running Fresh 3.1.0.1 and it is better.

Try running some of the older ROM's not based off the .47 OTA or the newer froyo and its gone completely for me..

[Q] Notifications bar not responding in portrait mode

Alright my screen itself may bed bad? I am unsure. I flashed CM7, and for a while everything appeared to be going smoothly. The real trouble began when I started playing Stupid Zombies(fun game, angry birds with guns and zombies). The game worked fine, but at one point the touch screen started acting weird. I would be holding my finger on the right side, but the cursor would be having a seizure on the left side of the screen. This random behavior didn't seem to affect the rest of the phone though, I pulled the battery and the same thing occurred. Eventually it simply stopped, but left me with a notifications bar that I cannot pull down in portrait mode. When I flip to landscape I can pull down the notifications bar, and the top part of the screen seems to respond just fine to my input. I reflashed and wiped and the same thing occurred. I flashed into a sense rom(while wiping of course) and my bar still will not respond to my touch whilst in portrait mode! I am vexed, any ideas would be swell.

If you wiped/reflashed and wiped/flashed a sense rom and still have the same problem, it might be a hardware issue! I'm not an expert on this but I had a similar issue on my HTC HD2 where part of my screen would work and the other part wouldn't, it turned out to be my digitizer that was messed up! I would take it to a cell phone shop and see if they can give you a free estimate on fixing your problem for you.
If you feel froggy like they say, try to do it yourself.....

I was afraid I would get this reply, I may indeed give it a shot myself. I'm pleasantly surprised by how cheap the replacement digitizer though. Thanks for the links.

Hi, I have a question. Did the digitizer replacement fix your problem? I am having the same exact issue with my girlfriend's EVO (rooted, with Cyanogenmod, done several wipes and flashes with no luck) Works in landscape mode, but not in portrait mode.
Get an app that highlights keypresses/gestures and test the area or test a different ROMs landscape orientation
Then you would know almost for sure if it was hardware.

[Q] Mytouch 3g Slide Screen Issues ? (WARNING : EXTREMELY LARGE PHOTOS)

So recently my mytouch has been getting worse and worse. I'm not exactly sure if it's me or if it's the stupid phone because it's been degrading over time for some strange reason. First of all, the camera is **** for some reason, this is my second replacement phone from T-Mobile and it's extremely blurry for some reason(apparently it's a common problem but not common enough apparently for the tmobile representatives I've met with have seen before). Secondly, it's been becoming unresponsive at times although i kill my apps after i'm done with them(I probably only have internet, and facebook running most of the time). Third, ever since I've factory reset it, it's become very glitchy for some reason. One of the problems is that I would close the physical keyboard but after sending a text and all of a sudden the screen goes black and the only thing to fix it is to hit the power button and press it again to get it off of sleep. Another problem is after i send a text i close the keyboard and the screen repeats but the location of buttons is still where they're suppose to be on the screen.
Pics of what I'm talking about :
First problem(Camera)

Decided to take a picture of me creating the thread if you can even see it lol
Third Problem(Glitchy screen)
http://i.cubeupload.com/ANHZ0t.jpg
As you can see the buttons are on as the phone is on but the screen is black and unresponsive, i realize i can still go to apps while like that somehow but to fix it i just hit the power button which shouldn't be happening though
Fourth(Repeat Screen)
http://i.cubeupload.com/ZLSu8o.jpg
As said before unless you didn't read this happens after i send a message and close the physical keyboard...
And thank you for any suggestions you guys have, help is appreciated, also for taking the time to read the thread
Jezussss!!!!
Dude.. you dont need pictures, and if you post them.. resize them first.
Make the thread want to be readable, like-able. Ask yourself, would you read this thread?? and with yellow highlights that no one can even see????????
You also need to post if you're phone is stock, what rom you are on, what version..

Sorry,thought they yellow would highlight it but it actually made it worse . I think the red is better with the whiteish background....
This is a stock version, I updated the phone to 2.2.2 but i factory reset it and now it says i have 2.2.1 even though i have 2.2.2 features like Wifi Hotspot,Wifi Calling, and images for contacts on messages...
im not sure, i havent had stock phone in a lonnnggg time..
Hopefully someone else can help you out

This is a hardware problem (the repeating screen) that seems to be happening to many people. (it happened to me before which is why i replaced my previous slide). After my 2yr contract is done, im gonna stop getting phones with keyboards because this also happened to my previous htc slider phones

So it's actually because of the sliding part of the phone ?
I'm not surprised, this phone was pretty cheaply made imo, literally a piece of crap :\
I guess I'm getting the new iphone once it comes out and my 2yr contract is done

Oh I see, well I tried to get it replaced but HTC was a bit suspicious when they wanted my credit card before anything ......
I have the same issue with my phone
As I was looking at your photos I realized I have the same issue going on with my phone. Does anyone have suggestions on ways to fix it? Personally, I do not believe it is a hardware issue. I do believe it is more of a software issue. That update that HTC offered is definitely screwed up! Ever sine I updated my phone, all of these problems started. This problem did not occur beforehand! My phone was working fine - before this "software update."
Same Problem
I had the same exact problem with the Repeating Screen (and completely agreed about the camera lol). Yesterday I tried demonstrating to my friend the problem, and permanently blacked out my screen. Now, the phone works in the sense that it receives calls, the home keys light up, and the camera still takes pictures. However, with no screen to select any options or perform any functions, the phone has been rendered completely useless. I, too, would like to figure out what the problem is and if there is any possible fix.
Sorry I couldn't be of much help. Just know you're not the only one lol
My girlfriend had the repeating screen issue back in May/June of this year. It was more than likely a software issue, because it became incrementally worse as the phone opened and closed until it came to a point where absolutely nothing could be done when the phone was moved horizontally.
I had T-mobile replace the phone at the time. Unfortuntely an idiot I work with who was supposed to mail it back didn't, I got stuck with an extra $360 on the bill.
Worked out paying for the phone with them yesterday morning, this morning my girlfriend messages me to let me know the screen is acting up again.
Potential Fix?

I would recommend replacing your flex ribbon. It worked for me, and from other threads I've read, I believe it's the cause of these issues. It's a pretty easy fix ( coming from me, who's far better at breaking electronics than fixing them, lol ).
Here's the flex ribbon that I bought off of Ebay ( it's the cheapest I found and it comes with the tools too ):
http://www.ebay.com/itm/170647168235?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
And here's a good video on disassembling your Espresso:
http://www.youtube.com/watch?v=-jgFHuVWlig
P.S.: I'd recommend being more delicate than he was with the volume ribbon though, as mine seemed very frail. Also, this video is for replacing the digitizer, so you only need to follow it to get to the flex ribbon.
A month ago, I had issues very similar to the ones you posted. Sliding my keyboard out ( in any way but gently ) would occasionally split the screen or freeze the phone. Even without using my keyboard, the phone would occasionally freeze while "settling" after the boot animation, and sometimes even during the boot animation. Slowly, those "occasionally"s become more and more frequent, until my screen just went black one day. The phone still seemed to work ( lit up when turned on, made sounds, etc. ), just the screen seemed dead. Figured that I was having a combination of software issues ( the random freezes ), and hardware issues ( split & black screen ), but replacing my flex ribbon suprisingly fixed everything.
This is what worked on my MyTouch 3G Slide
i just keep sliding the phone. and turn off the screen then turn it back on. but not turning off the phone.

Ghost touches in upper third of screen

Hi.
My Z1C seems to have a similar case of faulty display as described in some other threads here, but actually a bit different. The phone is stock, not rooted, running 5.1.1
Whenever I do something, there are ghost touches in the upper quarter or third of the screen. They only happen when I am not touching the screen myself. It happens no matter what I do. When I browse internet, it clicks links, when I scroll contacts, it calls people, when I am on facebook it gives likes etc... It seems like the more demanding task the phone is performing, the more ghost touches.
I turned on the developer settings and the "show pointer location" option, which leaves track of the last touch on screen, so I can research the issue.
I found out that when the phone is on home screen, it happens very rarely or not at all - the track of my last touch stays until screen turns off.
When I jump into the touchscreen service test, it does not happen at all. I can draw a line around the whole screen and it stays higlighted indefinitely.
In lock screen, it also doesn't happen.
I tried it in Sketch and it confirmed what I thought, when I was just sketching, from time to time a dot appeared in the upper part of the screen, but when the phone was downloading or installing in the background, the screen literally had seizures. I touched and released and then a storm of dots started to appear around the top part of the screen. It stopped after 5+ seconds, and after another input from me, the screen got another fit, drawing more dots.
I don't have any experience, but I think that since the problem doesn't happen constantly and it doesn't even happen at all in test mode, it could be a SW mistake.
I have found this thread https://forum.xda-developers.com/showthread.php?t=2691849 and I'm willing to try, but 1) my phone is still under warranty and 2) I have never done a root so I am not too eager. Do you think I should try that? Or has anyone found another solution for this problem?
Thanks.

As You have warranty, I would strongly suggest that You go for a repair. I had the same issue in beginning, ghost touches appearing randomly, going away only after reboot. I was rooted and xposed, so went full stock without restoring any apps or data from internal storage, yet the problem remained, thus ruling out the point that it was software problem. And then after a week or so, that much part of screen stopped responding to touch entirely. You can see details over here, Another user had same problem as Mine and had the same end result,
OK then, I'll go for a repair. Thanks for the tip.

I am having exactly the same behaviour as you described .
Ghost touches happening on the upper part, and triggered when a demanding task is running.
Actually I didn't realized completely about this, I thought it was just random, but right now after I saw your post, I tried an app similar to Sketch while upgrading apps or playing a video in the background. And dots in the upper part start appearing crazily.
Did the phone repair solve your problem ? Mine is not in warranty, so I'll have to pay for it.
But also in my case, before this thing happened, I got some water damage and that upper quarter of the screen stopped responding.
After replacing screen+digitizer I got this very specific behaviour you described.

In my case, I realized that I bought (probably) a badly re-fitted phone. Display's backlight was visible around screen panel edges, where I'd say it shouldn't be visible at all. I decided to return the phone and got a refund.

Ok. The aftermarket screen I got has that issue with the screen edges also. Very probable you are right.
In my case I water damaged myself. It seems that after 2 years of intensive use, waterproofing is gone, by accumulation of slight hits or so, never had a single crack on the screen. I read many posts reporting this happening, even with much less use time.
Too bad, I loved the phone, but I'm afraid that sending it to repair will mean to change the PCB or similar for a complete fix, which can come to a ridiculous price.
Seems it will be time to move on...
Yeah. If you want it fixed properly, you'd need to send it to Sony, and for the money it would cost you, you can probably gen a new phone. Sadly, similar phones aren't made anymore.

Small flickering line observed at left side

I'm not sure how to describe it - I may be paranoid or something but I've observed that sometimes while scrolling on the screen, i see a very thin line flickering on the touch screen for like 0.05 second then it goes away. It happened on the middle left side of the screen.
If anyone has observed this issue let me know as well. Thank you.
I've seen this as well, it didn't occurs everytime but you can see it, sometime on the left side close to the notch, sometime on the middle of the screen..
But until now, nothing to horry about, lets see in the next 3 months
Alright glad to know it's not happening to me only.
