My HTC Hero has various touchscreen problems among others. The main problem is the touch sensors do not work properly. I have to reboot the phone to get it working for a small while (roughly 10 minutes) before the screen craps out and does some very weird things:
It thinks I am constantly touching the top region of the screen
The touch sense overloads, meaning it senses the presense of anything around it. It is the weirdiest thing I have ever seen. I can hover my finger over the screen and it will allow me to control the touchscreen.
None of the other areas of the screen are functional except for the top, and whenever I touch the screen the Notigcations bar would come down. Sometimes this isn't the case and the phone just doesn't do anything upon touching the screen.
The battery life is very low.
Bootinf the phone takes a lot more time than when I first bought it, this is somewhat understandable however, having gone through many operation system changes.
I've lost all hope.
Buy one of these and replace the screen...

Are you running stock HTC Sense? Before I rooted and installed CM I had a huge problem with the stock Sense ROM, similar to what you were doing. Pressing buttons on it's own, the screen was shaking and would not stop and the screen was unresponsive. Once I got rid of Sense the problem went away and I haven't had it sense I flashed CM back in October.

Have you tried to do a full, complete wipe of the phone? Sometimes just doing a factory reset isn't enough. What recovery are you using?

I don't can't be sure but I thought I remember seeing a touchscreen calibration setting in the stock rom when I first got my hero. But that was a long time ago. Something you might want to look into.
Hope this helps. Good luck.
It is mentioned here. http://m.androidcentral.com/questions-about-sprint-htc-hero
Does upgrading the HBOOT help with the wonky touchscreen heat-related miscalibration issues that every Nexus owner knows about?
I raised this question on a different thread:
http://forum.xda-developers.com/showthread.php?t=903975&page=9
but wanted to throw this question out to a larger audience.
This week I finally got tired of having intermittent but definitive touchscreen miscalibrations, usually associated with charging and/or heavy usage. HTC shipped a swap for me to use.
The new one works pretty well, except the camera takes pinkish tinged images, so it unfortunately will be going back. However, I noticed that the HBOOT is the newer 0.35.0017 (though the date displayed by the bootloader screen is Jun 14, 2010).
So I upgraded the HBOOT on my original N1, and have been trying hard to reproduce the touchscreen craziness. So far I've been unable to do it.
It's difficult for me to make it happen on demand. I "stress tested" it essentially by doing the things that normally bring it on, GPS with charger, and graphics intensive games. But I'm getting really tired of beating angry birds again and again =P
So, if you're still experiencing touchscreen wonkiness that is fixed by turning on and off the screen, which HBOOT do you have?
There are of course many other potential mitigating factors I've thought about. Custom ROMS. Kernels. Touchscreen protector. Radio version.
Just for completeness, there are different part numbers on the two:
Original N1 part # 99hke002-00 F
Replacement N1 part # 99hke002-01
Who knows what the significance of that is.
No it doesn't.
Well shucks, I'm finding it harder and harder to get my touchscreen to screw up. I guess I should be glad!
How often does yours go off?
You know, as strange as it sounds, since I upgraded to the 0.35 HBOOT about a month ago, I have had zero issue with the digitizer. Call it coincidence, but that is what's happening so far.
We will call it coincidence for now =)
A happy coincidence.

Not very often, in fact think it hadn't done it over the past week. I've been using the crap out of it customizing CM7 over this weekend and no hiccups.
our touch screen is always a hardware problem..
That's not the question. The question is if you're still having a lot of problems with your touch screen, which hboot do you have?
I was actually kinda wondering the same thing. I finally got around to putting on CM7 (build 39) on Friday (coming from CM 6.1). I right away had the impression that the screen was more responsive (the notification drop-down bar tipped me off) and I have not had a single episode of wonkiness with the screen since. CM 6.1 was a little weird for me and I had screen issues (especially the drop-down).
Oh well, even if it isn't the HBOOT, something has changed for the better for now
Another thing I learned recently is that on the native google navigation app, there seems to be a touchscreen dead zone directly vertical in the center of the screen (in landscape mode at least). It basically corresponds to the current street you're on if your navigation is active and your path is straight ahead.
So if you touch there and try to shift the screen around, you might mistakenly think the whole screen is awry. I think this is by design.
I'm not sure why it's there but it reliably is unresponsive to drags. So I'm not using that center area to gauge if my screens gone wonky.
Now if you hit the menu button, the buttons centrally do respond to taps.
Just had my first case of misregistering digitizer in a while. But instead of the whole bottom 1/3 of the screen going stupid it was just the bottom right corner, around the enter button/backspace if you have a portrait keyboard.
Oh well, it still works better than stock eclair!
So just as an update, the HBOOT definitely does not rid the digitizer issues plaguing everyone. It seems actually that my kernel had more of say in when/how often the issue surfaces.
I found that on Enom's Froyo ROM, problems arose more often with stock Enom than Pershoot or Wildmonks. However, each kernel has its own benefits.
Is there any programme to for screen calibration? So part of the screen seems not responsive.
That is a hardware issue not a Calabration issue..
does somebody know if this "hardware issue" is present at all note's?
i found that my screen is a bit unresponsive at the top right corner. i cant draw about 2mm to the border of the screen (with the pen)!

However when I flash a new rom the screen get responsive for a short while. After that I need to press the screen harder. On the bottom right hand corner has this problem.

Did you ever solve this problem? Mine started doing it after it updated KL7 OTA.
Well guys I'd like for someone to chime in on this. I thought for sure this was a hardware issue. I'm on my second note now. My first note seemed like it was having issues with the lower right corner of the touch screen. I thought maybe it was a rom issue. I flashed clean KL7 and it seemed to suddenly be better then after a little bit it got worse. I have my second note and I flashed KL7 right away on it. Now after a little bit it seems to be getting less responsive, still better than my first, but I'm beginning to think this is a software issue. Any of you having these issues what Rom are you on? Should I try changing out this note for a third and see what happens? I may flash to some other firmwares to see too.
my top right is a bit unresponsive as well. . it works but seems a bit off. .
I used swipepad , really useful taskswitcher
It does not work when phone is connected any charger.
I've definitely noticed the phone being less responsive when on the charger, but this seems to lose responsiveness over time off charger and on battery.
I've had other phones that from time to time would act a little wonky when using them while charging.
Hey,
I've had some display problems, both with regards to calibration and also when it's charging.
I have made this video to demonstrate a problem I have of calibration. Watch how the display detects a signal at a point offset from where I press with the pen.
For me the problem I saw using the *#*#2664#*#* test is that the last 10 pixels or so on the 2 end sides of the screen don't respond.
For the pen offset is cause of the left or right handed settings, I find that holding the pen and rotating it so that my thumb presses the button of the pen instead of the indicator finger gives pretty good accurate results.
I'm definitely thinking this is at least more software related than hardware. I don't remember noticing any problems when on KJ1 or KK1. So I flashed back to KK1. It started it up and then I did a quick factory reset. This is completely stock/unrooted. Anyway bottom right corner seems to be having no problems detecting my touch now. I'll leave it on this for a few days and play around and see if it seems to lose sensitivity again. If it does I'll let you guys know, but for this to be a hardware problem I can't imagine it being this intermittent. Any of you on KL7 that mentioned this issue, are you guys completely stock KL7 or using the CF-Root Kernel? I know someone mentioned losing functionality in music player and torch and it seemed to be an issue with an alternate kernel.

That´s normal - pen is calibrated to use it at a certain angle - try to change the setup from right handed to left handed and you will see a different offset if you make the same test again.
The offset should be the same on each area. Only if this is not the case i would say, there is an issue with the screen.
Hey, ok so it is a deliberate software decision. Kinda sucks- I'd think I'd sooner like to have it type directly below where I write. I'm guessing it is an attempt to account for the fact that the glass has a finite thickness. Sooooo does anybody fancy writing a kernel alteration for this...?
i also find it more annoying than useful
Couple days on KK1 and what I thought was a hardware problem still seems to be fine. It's detecting much better in the bottom right corner where I was having issues on KL7.
I am having the same issue with the reduced responsiveness of the bottom right corner. I've noticed it after updating to KL7. Maybe is the driver of the screen.
Is there any way we could report this back to Samsung?

Hello.
I have the same problem ate bottom right side of the screen. I am ate LA4.
what should I do?
Although the problem was nearly imperceptible some days ago, while the note was connected to the charger, I've noted a very small area near the bottom right side of the screen where it was difficult to write using the stylus with SMemo. On the opposite side the loudspeaker is present; and so I've thought it might be correlated with the magnetic field of the loudspeaker. Today I've performed the *#*#2664#*#* test with and withouth the charger, but the problem is not occurred. Because of these devices are always more complex I prefer snap closures for my cases.
I'm facing a very annoying problem in my k3 note, that some areas of screen randomly stop responding. In my phone its mostly limited to bottom right part of my screen where backspace on keyboard is located. Rest of phone is responsive except this region. Restarting the phone fixes it temporarily.
But strange part is it doesn't happen on all ROMs, I first noticed it in some AOSP MM ROM, then i think it was Andronium VUI ROM (based on dev 1628) and now on s433 rom which leads to believe its some software thing not hardware thing.
Are there others also which face similar issue ? Any possible solution except switching to different rom ?

Yes, I have this problem with the screen also. I've heard from others with similar issues on other forums. It seems it is a hardware fault or possibly an issue with the way software interacts with the screen controller. In my case the screen is periodically unresponsive around the letter E or R on the keyboard and I have to tap the area with greater pressure. Sometimes it gets very buggy and very frustrating.
There is another possibly related problem when scrolling a web page or dragging - larger areas of the screen become unresponsive. Turning the screen off and then back on fixes the problem for the next 2 or 3 minutes. This issue has also been fixed for me with the kernel from daniel_hk here http://forum.xda-developers.com/k3-...rnel-dc-mtk-m1-kernel-vibeuiv3-51631-t3483573 - the only proviso is you apply it to Vibeui 1631. So while the scrolling issue seems to be fixed, the unresponsive areas around letters E and R on the keyboard remain.
I've noted the problems above would temporarily go away after flashing a new ROM however they eventually return. I've considered buying a new screen but not really sure if its a hardware or software issue - possibly both!

hmmm it's interesting that different people have different areas of unresponsive screen. It seems more like software issue to me, as I started noticing this issue more on newer dev roms only. Today, I've reverted to dev ui 3.1 1622st as I remembered it didn't have it. Will report in couple of days of how it goes, so far haven't noticed it.
I have been facing touch problems for quite some time on the ROW version of the ROM s433. The touch starts acting weirdly, i.e random things start getting touched automatically and this happens mostly in the lower half of the screen. I turned on the show pointer location option from developer settings and it shows the pointer stuck at one point on the screen showing erratic behaviour. Turning the screen off and then back on solves the problem but very temporarily. Restarting solves for a longer time but the problem pops back up.
Hi mates, I need you help and suggestons,
unfortunately my phone felt down and I needed to change screen, the service which installed it asked me to choose one of the available (chinese) screens I I select the most expensive one. In the beginning all was ok, but time by time (about 1,5months) the usage gests worst, when the screen start to be a bit dirty it start recognize touches anywhere (moslty in the up side of screen), itself does commands, it's not possible to do nothing. WHen this happens I need to keep press the power button for 10 seconds tille ht ephone reboots, after reboot all become regular.
My considerations:
1) it doesn't seams a defective screen or a bad assembly, because after reboot all is good, if there were such problems a simple reboot can't fix them.
2) it looks like an incompatibility between OS and the touchscreen firmware, and probably it's something Xiaomi does with intention to create problems for cloned spare parts. Maybe the OS is "instructing" the touch screen controller how much sensibility to use, how much it can be dirty, etc.etc? the protocol of the latest OS isn't at all compatible with the cloned device and it result on crash of functioning. A reboot solves the problem.
If that is right, will a ROM update to another OS (not IMOU, as I have now) can fix the problem? Or there is any app that can perform a touch screen reset? Or any other trick to solve my problem? Than you for answers
Hi mates I need help, with cold weather coming it got crazy as soon it feels cold. WHat can I do to solve problem?
Updating ROM to a non official can solve it? The display isn't broken! A reboot fixes always the problem..
It is not original screen from xiaomi vendors, just a oem part with lower quality (chinese sell it alot on aliexpress with many type amoled, oled and LCD panel too).
Ghost touch easy happen on oem screen no matter how expensive it is.
Thank you for your kind answer, this is a really big issue.. it's very annoying using the phone like that, I've noticed it suddelny starts when the phone is exposed to cold temperature: lowering the screen temperature quite suddenly means it goes crazy, when it's crazy the only way to fix the proble is reboot the phone, with reboot it calibrates again and works ok, till next event. MY question are:
1) Can I forse myself a calibration?
2) Does other ROMs, not MUI, manage and fix this problem? (using another touch driver may solve the problem, chances are MUI introduced updates and become more selective to work with only original displays, to disancurage the OEM parts, so using another ROM wuth an older driver may solve the problem)
3) If I buy and add a protective glass on display, does it behave better?
Your experience is essential for me, thank you for posting!

imo
1. you can not
2. Roml sorfware can not
3. Protective glass make lower touch experience.
- Not all oem part come with defect, some working fine, it is just random.
- To repair you need replace new one, or buy original screen for sure.
Thanks for answer, I do believe that the problem can be managed by drivers, "resettig" the touch chip wil correct the problem. Probably the defect is on the firmware of the touch panel, it gots errors from touch.. ok, but it doesn't understand it's just revealing mre and more ghost touches. These FW have the task to filter out the ghost,, maybe they don't do it well.
A second chance is the comuinication between this chip and the MUI OS, the connection goes broken by some mistakes, "unalligned" and MUI got any touch position from nothing.
I don't believe the screen is defective, because after reboot it works perfectly, thil the next strong environment conditions change..
What is Roml software?
