Temporary Touchscreen "dead" spots - HTC Inspire 4G

I recently rooted my Inspire (2 days ago) and just today ive noticed that im getting dead spots on my touch screen. Its most noticeable when im typing something and one of the keys will hardly register. I will have to push multiple times, harder than I would normally have to for it to register. Rebooting the phone fixes the dead spot for a while, and then a new spot will have the same issue a little later. If anyone has any suggestions or and ideas on what could possibly be causing this I would really appreciate it.

What rom/kernel are you using? A lot of people were having that problem, including myself, and to my understanding it had something to do with the drivers. I believe Lee's latest kernel addresses this problem.

I've noticed this while using the CoreDroid ROM and the Gingerbread keyboard. I switched back to the HTC keyboard and deadspot is gone. So my guess is, its something with the GB keyboard.

Well I am using LeeDroid Rom. Does the regular rom itself not update the Kernel aswell?? Sorry if this is a dumb question, this was my first time rooting.

It's a well documented bug. It's hardware problems with inspires

same here, using Coredroid V7(even before v7) and Lee Kernel 3.1.7 BFS.

same here.. its always the A and the O with almost every rom..

@OP:
This is a known touch screen drivers issue. Only way out is to press power for screen off, and then press again for screen on. I don't think any of our devs here can do anything about it (atleast I assume so, with no doubts about the abilities of our devs).

I have found that doing a screen rotation works too

Great! I generally (close to 95%) have my screen rotation turned off, so didn't notice it. Thanks for the idea though.

Homescreen will change screens without touching it?

I'm curious if anyone else is experiencing this issue..
When I'm on the homescreen and not even holding the phone, it will mysteriously slide to the screen on the far left on its own?
Anyone else having similar behavior?
I'm temp rooted on visionary and running 7 homescreens..

Not sure if it's the same thing but it was reported in G2 forums many times. What happens is the light will hit trackpad at just the right angle for it to register and move. If it happens again, try moving the phone to a different spot and observe it. If you see the same behaviour - you may have a defective unit and may need to exchange it.
Good luck.
When exiting the stock Froyo Car Dock (I prefer this to the T-Mo version), my phone will almost always jump directly into the 'Expose' window mode of the five home screens, without hitting the home button or touching the trackpad. It's probably not related, but it does appear to be a strange glitch.
As for your exact problem: I haven't seen it happen with mine yet. Good luck.
It does sometimes to me. I thought im trippin.

Ah that very well could be the issue! I'll mess with it over the next few days and try to narrow it down. It never occurred to me the trackpad light sensor could be throwing it off..Thanks alot!

Odd problem

Okay for a good month and a half I have been having an odd problem. Sometimes randomly my phone will start glitching and viberating randomly like I'm pressing the soft buttons below the sreen and sometimes that menu comes up like I pressed the menu button. Not the launcher. Ans also I can be in gallery and select a photo and it will viberate like I hit the back button and it will go back and I have to select it a few times before it stops. What could it be? It even done it on froyo

That happens to me every once in a while, the whole system will just hang and the menu will come up or the recent apps thing will come up multiple times and the phone will vibrate, then it just goes back to normal.

Yea. What's causing it

Could be a bad flash, or some app has created a conflict, seems to me I read there are a couple of apps that caused this. You could just reflash a different rom, see if that fixes it.

once every few days why? I think its hardware not software. cause No matter what rom I have had even 2.2 and stock it still does it

From my experience you can get some oddities such as this as a result of a bad flash (which re flashing would correct as stated above) so I'd say your assumption is probably correct and your problem may be with the hardware.
I don't want to ask the obvious question but no one has. Have you dropped it any? Or has it been exposed to any kind of water. I had a phone freak-out on me when usb port got a little wet from some rain.
Just when you think you have it idiot proof, they come out with a better idiot.
not been wet and its not a bad flash. Right now I'm trying out froyo again and it done it again last night. I'm a uscellular agent. And I have yet to have anyone else come I. With the same problem

I believe this happens on an undervolted kernel un areas of extremely low signal. Recently, it seems to be happening on any kernel. I hope this get's addressed in our real froyo release.

It happened when I was on 2.1 as well, Usually only when I had a bunch of things running. Im an agent too! xD
OK my phone stopped for a few days I haven't had a case on it. Then today I pit my case back on it and it started doing it earlier for the first time in days. The case doesn't over the front of the phone at all
Sent from my SCH-I500 using XDA App
Yea, that sounds like it may be the case :s I've had it happen a couple times, but I thought it might just be like my fingerprint is over the button and keeps presseing it. I just wipe my finger over the bottom of the phone and it stops. Don't know if its the same thing.

I think you are right I've had the same issue and if youlook at the soft keys when it happens you'll see that one of the buttons thinks it's being pressed I think it's just a hardware issue cause like you said when you run your finger over the keys it stops.
Also, similar problem every once in a while when I'm trying to swype during a swype it acts as if my finger lost contact with the screen but I definitely didn't lift my finger abd it happens several times in a row until I lock the screen turning the touch screen off it seems to reset the touch sensors.

or it's a ghost, woooooooo!
I've experienced this issue before, although very rarely. Every time it has been the menu button and it always seemed to be in colder weather. I use a thin screen protector I picked up at a USCC store. Happens even more rare with EA11 leak however my screen brightness changes (occasionally) when I end phone calls and am in the middle of an app

My touch screen stop working when I turn the phone upside down.. Not sure if this is the same problem.
Haven't had this happen. I've only had the auto rotate stop working.

Honestly that's a really great idea if it was a feature. Think about it no more accidental answer/deny when pulling it out of your pocket if you put it in upside down. And how often if ever is the phone used upside down. I'm calling for a patent on this one!
I have this issue.
I have this issue and it goes far beyond the keyboard. I will be playing fruit ninja and half the screen will be unresponsive. Its happening quite a bit and I am thinking about exchanging my phone.
Same here
I've been having the same problems but I think it has only happened to me when I use custom ROMs such as Cyanogenmod or Coredroid. When I went back to stock I don't remember it happening.
I was running Coredroid V8.1 a few weeks ago and didn't like it because the font looked terrible but I think the keyboard didn't give that problem, it was with an older version of CD. Right now I am using Cyanogenmod 7.0 and it happens a lot and gets annoying. I now for a fact that is not hardware since the keyboard will work normally on landscape and other stuff will respond to the touchscreen.
Still trying to see if there is some sort of fix or to use a new keyboard. Installed GO keyboard and same thing happened, now using Swiftkey X and it happened also but now I took the protective case to see if that has something to do with it LOL.
edit: disregard.
ive had this problem also for awhile. i dont remember having it on the factory rom, but that was awhile back also. ive had it on every custom rom that i can think of. i used coredroid and cm7 for awhile. right now im using miui. ive tried 3-4 different keyboard at least, and had this problem with all of them. the keyboards accuracy also seems to decline. when switching to a new keyboard the problem initially goes away, but it eventually starts doing it again with the different keyboard.
I would try come non CM based roms as I have seen this come up a few times and the omr thing most have in common is that it shows up on CM based roms like MIUI. I have never had this issue on any sense based rom so that would lead me to think like wifi and Bluetooth that it is due to the non OEM drivers CM uses.
Coreddroid is a sense rom, and I had it back then. I've been using absolution, which is cm7 based, and have not since had the problem. The problem has also been reported to occur on non rooted, stock phones.

Nevermind that, I still have it.

Keyboard/screen acting funny.

I have a strange problem. Occasionally my phone will refuse to let me type a letter. It generally happens towards the bottom right of the screen. However that isn't always the case. For instance I wanted to press the letter N today but it refused to let me. It would press every key around it but it wouldn't press N unless I tried multiple times. I have a screen protector on if that makes a difference. It really is annoying. Is my screen possibly defective?

Sometimes this happens to me when gunk and dirt build up on the screen. Usually I just take my shirt and wipe it off real good and it works like it's supposed to.

Alrighty. I'll give it a shot. Thanks.

Could also be something under the screen protector messing with the capacitance. Maybe a small air bubble that gets pushed out of the way when you repeatedly try tapping there. Just a thought. If it's not a hassle, I would try using the thing for a day sans protector and see if the issue replicates. If anything. it will eliminate the screen protector as a possible source of the problem. I'd gather, if you aren't rooted and running a custom ROM and the problem still exists in the absence of a screen protector, it is a manufacturing defect.

I am having the same problem and have had little gremlins like this come up. My phone is rooted by the way so if it is a manufacturing defect then I guess I am up the creek (voided warranty). It is annoying to say the least my t, y g h and v and b keys react as if they were not on the keyboard at all. Luckily the word recognition helps out but its frustrating. I have had more problems with this android phone than I ever had with my windows HD2. I miss that phone...no worries ever.
I would really advise you to exchange your phone for a new one if you are having problems with the touch screen this early on. Manufacturing defects like that don't go away and can only get worse. You can still return/exchange your phone if you are rooted, you just have to return it to stock before you do so.
This has been happening to myself and several others, and there have been a few touchscreen problem-related threads on here and other forums. the letters I can't type are fairly random but it usually seems to be t, s, and some vowels. it's either a software or hardware issue, since it is completely random and the problem fixes itself when you begin typing another word.
you can also try pressing the letter with your whole finger instead of the tip. it seems to work more often than pressing the letter 20 times before you flip out.
Anyone with this problem, is the touchscreen ever not responsive with anything else?

I thought about exchanging it but after reading all the issues other people have with replacement phones (or their first, even), I'm not sure I want to take the chance especially if it's a software issue.
Happens to me to, I am rooted and running a custom rom. It's a problem with the HTC keyboard. If it happens just hit the back button then bring the keyboard back up. Or install a new keyboard from the market like Better Keyboard.

Not true, had this problem on my Fascinate before the Thunderbolt.
Something stupid to check, do you have wavelauncher installed? That was giving me fits for awhile before i figured it out. anything by the bottom of the screen just wouldnt work.

Dead Spot On Screen

When I try to type on landscape mode the "t" will not respond when touching. Could this be an issue with a Rom or screen?
I had mine do that with the backspace button, i flashed another rom and the problem went away, not saying that this your problem just a thought...

Thanks. I'm on coredroid 7 right now. I may try another Rom to see if it goes away.
Though I haven't experienced this personally, thankfully, this sounds like the "unresponsive keyboard" problem experienced by others across several different roms.
Most people tend to automatically assume the ROM they are running at that moment is responsible, when in actuality, it just happens to be the first time the problem surfaced for them.
It is suspected to be a bug in the touchscreen driver for the phone itself, not ROM-specific.
If we're talking about the same thing...
I believe Scott_S to be correct, LeeDroid reverted the kernel to the older FroYo touchscreen drivers on his kernel a revision or so ago and since then my screen has not had any "dead spots"
So you could possible try his kernel on your ROM of choice and see if the problem goes away

I have had this happen on random letters with completely random ROMs. A reboot usually fixes the problem for me. Sometimes just opening and closing the app I am using will correct it as well.
Whatever wad going on has stopped. My guess is the kernel too. For some reason my phone doesn't like the leedroid kernel.
