Even when typing at normal medium speed I find the keyboard will completely ignore/miss a letter or two at fairly regular intervals. I've tried editing the registry to lower the initial delay value down all the way to 1ms, but the issue still occurs. Is there a known cause/fix for this? Thanks...
try either of the last two cabs found here

Thanks.. I took a look and the issue I'm having seems to be a bit different from what those cabs address. Rather than oversensitivity or extra unintended keypresses, my screen/keyboard will semi-frequently (every 20th word or so) just momentarily become unresponsive and completely miss about two letters of keyboard input.
It's like the keyboard just locks up for about half a second and doesn't even display the little popup letters over the keys at all, and when it un-freezes it doesn't "catch up" or realize that two more letters were typed in the meantime. so if you were trying to type the word "keyboard" you would very likely end up with something like "keoard" as the two missing letters are just skipped completely.
Normally the sensitivity of keyboard and touchscreen in general is very very good and I only have to touch very lightly to get a response. 19 times out of 20 this is the case with typing on the keyboard no problem. Just every here and there semi-regularly a couple of letters will invariably get skipped, again without even displaying the popup boxes over the keys, and I'm not even typing particularly quickly either.
Are there any cabs for this issue..?
Just following up to my thread here from almost a year ago. I've tried multiple roms from XDA, as well as registry tweaks and fixes, and still cannot solve the problem. Does anyone NOT experience this problem, ever..? If you don't, could you please tell which ROM you're using, and what (if any) registry edits you've used?
It is completely impossible for me to type any medium-length sentence on my HD2 without at least a couple of letters/keystrokes being missed and ignored entirely. Every time. I'm willing to try anything but I desperatelty need help, as this one glitch renders an amazing high-end smartphone totally unusable for me...
What ROM are you using now? I am running the T-Mobile 3.14 ROM and I have similar priblem with my keyboard but not near as bad as you say you do. I have not tried tbe reviztry tweek hou mentioned previously in this thread.

Currently I have Dutty's ROM installed but I've tried multiple other ones including Energy, Elegancia, Laurentius etc, and the problem is always there, so I don't think it's the fault of any of the ROMs. Either I just have a bad unit, or all HD2's do this to some extent and the vast majority of owners just consider it an acceptable quirk and don't bother complaining about it.
The touchscreen on my HD2 is extremely responsive and fast in all other scenarios, and even when typing most of the time, so I dont think it's defective per se. It just seems that with a good degree of regularity the phone/OS decides to completely "pause/freeze" for a half second or so before resuming normal operation. So brief an instant that it isn't noticeable under any other cirumstances except typing on the keyboard, where it's long enough to eat up anywhere between 1-3 keystrokes depending on entry speed.
It's really a shame, because the Leo is in many ways the most powerful, super awesome smartphone I've ever used, but because of this one utterly intolerable bug it sits on my shelf totally unused, currently in favour of my Sony Ericsson Aspen which is far less powerful, but at least reliably useable for typing.
I'd be willing to buy another HD2 if I really thought it was my specific unit that was responsibe, but right now I have no dependable way of knowing that.
Have you tried other keyboard applications?
I found this cab in my sd card.
I remember it worked in my Topaz.
Give it a try.
I will give the cab a shot tonight when I am back at home, thanks. I have indeed tried alternate keyboards such as Resco and a few others, with no change or improvement, so I don't think it's the HTC IME keyboard specifically at fault either. My guess is that the whole screen is becoming unresponsive for that half second or so, not only the keyboard. It's just that it's only noticeable/irritating enough to be an issue when typing, because I have to constantly stop and go back to re-enter letters that were ignored along the way. It's a real dealbreaker for me on an otherwise outstanding device.
Do I take it correctly that you yourself never, ever encounter this issue when typing on your own HD2? Again for the record, it's not a matter of my typing too lightning fast for the Leo to keep up with. Even typing at moderate/regular speed (2-3 letters per second) the missed key issue occurs regularly.
I tried the cab but no luck unfortunately... I really wish I knew whether it was a problem with my specific unit or a model-wide issue that just doesn't get mentioned that often.
Is there anyone reading this, who has an HD2, and does NOT ever encounter this issue of typed letters/keystrokes being missed? Is there anyone out there who can say that their HD2 catches every keypress, every time without fail?
If this is true and applies to you, please respond and let me know! If there are units out there that are totally free of this problem, then I will not give up hope, and will try to replace mine. But I need at least a confirmation or two that some human on the planet somewhere has an HD2 that does not experience this problem...!
I Think I May have found the cause of the otherwise apparently 'random' freezes/hangs and total lack of touch sensitivity.
Basically, In my case at least, It Is the G-sensor/accelerometer.
I have been noticing increasing numbers of these freezes on Mattc 1.5 Froyo, Mainly in Landscape, Mainly in games.
TEST:
I installed 'Iron Sight' Game. (If theory is right then you should be able to use any landscape game, but please try Iron sight if possible.)
I Ran the game and it switched to landscape,
SO I PHYSICALLY TURNED MY HD2 TO LANDSCAPE.
THIS IS WHERE THE FREEZING AND LAGGING BEGAN!
On the Main menu found it difficult to press any options.
When I did manage to start a Game The control buttons were hard to press and the game was unplayable because screen sensitivity was just not there most of the game.
I Then Physically turned the HD2 around and Back to Portrait orientation, AND ALTHOUGH THE SCREEN ORIENTATION STAYED IN LANDSCAPE I DID NOT EXPERIENCE ONE SINGLE LAG OR FREEZE.
BUTTON PRESSES WERE RESPONSIVE TO TOUCH AT ALL TIMES FOR AT LEAST 15 MINUTES!
HERES WHERE IT GETS MORE INTERESTING....
I Then Turned the HD2 back around to landscape again and the Problems IMMEDIATELY RETURNED.
I THEN HELD THE PHONE VERY STILL IN LANDSCAPE AND AFTER A FEW SECONDS THE PROBLEMS/LAG/FREEZES DISSAPEARED AGAIN!!!
TESTED REPEATEDLY!
IN LANDSCAPE AS SOON AS THERE IS ANY PHYSICAL MOVEMENT, THE GAME FREEZES, BUT IF I KEEP IT STILL THE GAME RESPONDS PERFECTLY WITHOUT HESITATION.
Can some of you please test this theory?
A cradle/Dock would be handy for testing but it is possible to keep the phone still enough in-hand in my tests.
Use the game "Iron Sight" where possible, but use other games/apps too if you have time or inclination
Post the results below ( with logs where possible ?) Please.
Note:
After discovering the above, I did a search on XDA and found that a member called 'Hinky' and touched on this but I think I have narrowed it down.... I think
Please test and confirm (or debunk lol).
Thanks.

Yes this is something that the devs have been discussing. It does seem that the freeze issue is in fact related to the g sensor. I don't know if anyone is working on it at this time but I believe Cotulla will try to sort it out for his September release

Lol keep with the testing though I didn't figure that much out
Hmmm this is def the prob for my touch screen issues. I tested a bit using the latest mattc Leo + Froyo w/Sense 1.5 version, with latest FULLRAM. I found that while on the sense home screen if I hold the phone out in front of me either landscape and portrait it's ok, and I can do whatever I want at full speed no lag at all. THEN if I lay the phone flat, It freezes. I did this like 20+ times and every time It would freeze whether I was playing a game or reading an email.
This also happen to me. Using Mattc 1.5 Froyo, it happens when using internet browser. The screen will freeze or not response right after i turn from Portrait to Landscape or sometimes have to wait for few seconds. I have to turn my device from Landscape to Portrait, and back to Landscape again, then the screen responses back to normal. This also happens in Copilot app when using in Landscape mode.
I turned off the screen rotation
What I did since i installed my ROM with 380mb ram is to turn off all screen rotation settings, so far so good, I haven't notice any freeze or lag so far in any application or while waking the device up, I used to have it and I hate it, I almost went back to Winmo!!.

Did you fresh install 1.5 or upgrade 1.4>1.5?
I had quite a few freezes on 1.4.
Then I upgraded to 1.5 and kept my apps etc from 1.4.
I HARDLY HAD ANY FREEZES AT ALL
Then I did a fresh install of 1.5 and started getting LOTS of freezes.
i did a fresh install.
i deleted all android files on my sd card and extracted the new build to a new made "Android" folder...
i use xanny roms, and i still have the robovoice problem, so i can´t use android daily...
i noticed on all android builds ive tried sofar, that the polling interval of the gsensor is very bad/small. U can see it when u go to calibrate the gsensor, the bubbles move very slowly...
this is not a big thing when u only use the gsenor to turn screen to LS, but it is essential to play games using the sensor...

Lol, no worries I'm glad that you pointed it out. This was actually one of those really useful threads and the kind of thing that the developers are looking for. I am not a dev but I speak with them pretty regularly when the same issue are pointed out time and time again by those who do not read the threads. This was something that has not been talk about here so I appreciate your well thought post and the information that you provided
I was just a step before creating a new thread about it when I saw this one.
This is definitely one of the things that are really pissing me off using Android.
Furthermore, I did tests on this issue for quite long to doubt that it's an autorotation related issue. Maybe it has something to do with the g-sensor, but it still would happen randomly even trying not to move the phone at all. I noticed that the problem wouldnt appear that often when decreasing the polling interval of set cpu and same time increasing the min. freq. to 380, but still, it DOES happen.
I'd really appreciate any statement on this, developer side of course.
I have the occasional screen freeze on landscape, but not very often using froyostone.

Cheers for that ^
+1 for the Gsensor polling intervals seeming very slow.
THIS CAN BE SEEN VERY CLEARLY USING THE 'VR TUNNEL' LIVE WALLPAPER.
Here the cubes move smoothly at a good fps while the tunnel moves around at what appears to be 4/5 fps.

Possibly not related to autorotation per-se, but...
With Autorotation disabled... If I turn my phone on its side (with volume buttons pointing towards floor) I still experience freezes on my home screen or anywhere else for that matter.
Plus I have found that holding the phone VERY still in any position seems to eliminate 'ALL' freezing and lagging problems.
Do the G-sensor and the Dgital compass 'interlink' or communicate in any way? Is it possible that the screwed up compass output is screwing with the g-sensor output?
I ask this because the game 'hungry shark' thought that my phone was flat whent the usb port was pointed down towards the floor.
Dont know if that makes sense but for me it seems like the g-sensor is fubar as well as the digital compass.

Well ofc, it wouldn't freeze when it's COMPLETELY hold still, but I guess that shouldn't be the point of daily usage.
Now when it comes to spontaneous outside actions, you are trying to pick up a call using touchscreen cuz ur used to it or trying to shoot out a text in hurry, and your device will just go sleep for some time. I mean, how'd you hold still if you're moving (fast)?
If you ask me thats pretty much a major bug, not to forget the 3g data thing. I'm not moaning around, just want to attain more focus on this. I notice people losing themselves in some benchmark trolling - just time waste.
There is already a thread for that (walking dead)
Just found a possible solution, please repport if it is better for you too :
- boot windows mobile, calibrate the g-sensor in settings (i did it 2 or 3 times, but i don't think its important)
- do a proper shutdown of wm
- restart wm + android

After disabling "Auto-rotate screen" I haven't had a freeze yet, so good so far.
I've got an HTC Hero, it's GSM, ever since new I've found the keyboard to be incredibly frustrating. There's quite serve lag in many apps, typing in forms in some webpages is nearly impossible. Even the built in apps like SMS have lag. It's worse in landscape mode too. Sometimes it'll even pause for half a second mid key press and register that as a long press on that key (although this might be scanning for wifi, because bluetooth audio seems to hitch at similar intervals unless I turn it off)
I've tried countless different 1.5, 2.1 and 2.2 ROMs, with and without Sense, some are slightly better but they all suffer from it.
I've Googled it and surprised to find I don't see any other complaints in the internet about it, finally I've decided to post a question here. I would be guessing hardware limitations, either digitiser or the processor is just too slow.
Would be keen to here other people's thoughts on this though, has anyone managed to fix it?
Edit: I should add that I have the vibration on key press off already.

No lags here. Have you tried using lower overclock if you tried Froyd, since it doesn't need overclock to get higher speeds. I run on stock speeds, and have no lag issues using any keyboard in particular.
How bad a lag are you talking about? The hardware should be more than capable.
EDIT: hold on, are you meaning the keyboard is laggy. I think this is just the keyboard itself. Try something like ultra keyboard or swiftkey?
Yeah, the keyboard is laggy, I can almost type twice as fast as it comes up on the screen when it's at it's worst (usually in a webpage typing in a form). I haven't tried either of those keyboards, but I've tried other keyboards including the standard 1.5, 2.1 and 2.2 ones with the same problem.
This is a Hero issue, Froyd is a good rom works to reduce the lag for me
With the new cronos 1.3.0 all lags are gone. I had this issue with all roms before too.

Firstly hello to all my fellow Vega UK users!
For the price I think this device is great, but it does have it's issues.
Do any of you have the problem where the touch screen just seems to stop working? It'll kick in again soon enough, but it's frustrating as hell.
Also sometimes the task manager seems to appear by itself, but I can;t get it to appear when I need it?
I'm using Pauls Add-on ROM. (thanks Paul )
Logicalstep
I havn't had any major lag at all.
What do you mean by task manager? do you mean the one when you hold "home"?
I have found after a lot of use, with a lot of apps open that the system can lag. I guess this is due to system resources. Recommend installing ES Task Manager from the market to manage running tasks.
You mentioned the task manager appears by its self, do you mean the home screen selector? I found hitting the home button to many times makes this display.
Some users have reported issues with the touch system when the tablet is charging. Do these issues only appear when plugged in?

Yes believe so. due to non regulated power supply causes the screen to become over sensitive.
I get this issue too occasionally, vastly increased when plugged in, now and then when not.
I dont use the machine when its charging.
No real rhyme or reason to it occouring in my experience, id love to know of a cause, other than dirty screen.

Yeah It's a bit of a strange one tbh.
Can;t say I have noticed the lag more when plugged in. I though the PSU was regulated, isn't it just a standard Switch mode PSU?
On the task manager, well obviously there is a task manager with Foryo and oon my Galaxy s I hold the hold button down and it appears, however there doesn;t appear to be a reliable way to do this on the Vega....or am I wrong?
Logicalstep
I never get any touch lag, but I'm not convinced "lag" is the word you want.
"lag" would indicate that the response is somewhat behind the touch action. Android versions below Gingerbread do suffer from that when the CPU is loaded but the Vega is better then most in that regard.
What it does suffer from a _lot_ it erroneous and missing touch events (especially when using a poorly smoothed PSU like the one provided) symptoms include:
1. Swipe gestures being terminated before you lift your finger.
2. Long press actions acting like multiple-presses.
3. (The most common for me) Finger up events failing to register (resulting is erroneous long-presses)
But none of these are "lag". I believe there are grounding problems in the Vega and thus how you hold the tablet and the humidity and static of the environment can change the reliability of the touch screen. It's been reported that having the Vega plugged into a desktop via USB increases the reliability of the display (at least when also charging) which lends credence to the idea that it's grounding related.
What I have noticed ín particular is that holding the tablet in landscape mode makes the keyboard ultra inaccurate. You must press much below the level you want. E.g., if you want to write a Q you hit the A key. It's a bit bothersome while writing...
I haven't experienced any lag, just a slight deadzone at the bottom of the screen and inaccurate keyboard typing. Nothing major. I also haven't really noticed the messed up screen sensitivity when charging that people have been going on about.

Well for me the keyboard is still a major issue. Not lag really, but it appears to register my touches multiple times. Right now Im typing this reply on my tablet and I have to go back so many times to correct multiple characters, spaces etc. Its just taking so long and requires so much effort to write a simple message.. for browsing and apps I love it but for email its horrible..

OK just to be sure...
Is the power supply plugged in? (Screws up the calibration in my experience)
Are you touching the screen while it calibrates?
OK, so here's my problem. I recently returned my nexus 7 for a newer production date build because I had a horrible touch screen. I updated the new one and had missed touches/sticky keys but when I unlocked it to apply sfhub's fix it wiped everything and the problem is gone (maybe a bad upgrade install?) Every once in awhile it feels like it's still missing a touch. Like once every couple hours. I've noticed that the touch screen is very sensitive and if I move my finger a little bit while touching it registers as a swipe I guess. Is there a way to see if it's really not seeing the touch or registering as something different? There are no sticky keys whatsoever and multi-touch seems to work fine in a case or out. Does anyone else see this with theirs?

Enable developer options and see the touches
You can test/verify the touches by enabling the developer options on the Nexus.
To do this, go to settings, go down to "About tablet", and then down again to the build number. Tap the build number information ca. 5 times (5 to 10? after a few taps you will see an info sign about how many times you still have to tap), this enables the developer mode.
In the settings menu there should be now a new item, Developer options (just before the About tablet). In the developer options check the box named "Pointer location".
Now when you touch the screen, with one or more fingers, you can see a screen overlay with coordinates and axles showing where the device sees your touches.
I have the touchscreen problem with missing and sticky touches and pinch and twist problems, the whole menu. For example, using google maps or writing emails is a pain in the ass because of these touchscreen issues.
On my device once I enable the "show the pointer location" -feature, I can clearly see that the device registers the touches right, but it behaves differently from the touches.
According to this I see, at least on my device, this more as a software than a hardware problem, and it looks that the problem is maybe even on a higher API level, which is IMO a good thing, because it _might_ be fixed with a firmware update. The question is, why Google hasn't done this yet, as the issue has been there around the world for a while, and there have already been a couple of updates (Q & R, or even more?) which haven't fixed the problems.
It would be interesting to hear reports of other devices. Test and report!

You can test/verify the touches by enabling the developer options on the Nexus.
To do this, go to settings, go down to "About tablet", and then down again to the build number. Tap the build number information ca. 5 times (5 to 10? after a few taps you will see an info sign about how many times you still have to tap), this enables the developer mode.
In the settings menu there should be now a new item, Developer options (just before the About tablet). In the developer options check the box named "Pointer location".
Now when you touch the screen, with one or more fingers, you can see a screen overlay with coordinates and axles showing where the device sees your touches.
I have the touchscreen problem with missing and sticky touches and pinch and twist problems, the whole menu. For example, using google maps or writing emails is a pain in the ass because of these touchscreen issues.
On my device once I enable the "show the pointer location" -feature, I can clearly see that the device registers the touches right, but it behaves differently from the touches.
According to this I see, at least on my device, this more as a software than a hardware problem, and it looks that the problem is maybe even on a higher API level, which is IMO a good thing, because it _might_ be fixed with a firmware update. The question is, why Google hasn't done this yet, as the issue has been there around the world for a while, and there have already been a couple of updates (Q & R, or even more?) which haven't fixed the problems.
It would be interesting to hear reports of other devices. Test and report!

Yeah i feel the same too. I think the problem is software/drivers related than hardware and i dunno if there is a "perfect" device out there at all. I feel many casual users are simply not experiencing it. What i find odd is that, it always feels better after a reboot and things start to deteriorate from there. Almost like memory is not being released properly and there's some stucked process being stacked etc etc. Personally i find that eliminating the use of Chrome entirely has worked better for me. Am using only Dolphin now and it's been going very well so far.
The latest touchmark results shows there is a high latency in the Nexus 7 2013 model. It also indicates that it could be due to frequency of CPU polling for touches with a combination of other things in GPU too. IMO i think the high DPI on the screen and the handling of the quadcore processor might require some tweaking to get it perfect. There seems to be too much latencies and perhaps the missed touches / stuck touches are due to a combination of problems in the code with regards to touch events handling. Oh well, regardless i think they need a taskforce behind it to resolve it.

Thanks lomonic, an interesting link.
I had the former/original Nexus 7 (until my oldest daughter accidentally dropped it in May), and it had no touchscreen issues, at least nothing as bad compared to my new Nexus 7 (2013 model). Yes, it lagged sometimes, as does also my Nexus 4 (mostly noticeable when you slide down the notification menu or open the open applications list), but it had no similar problems with the precision of the touchscreen of the new Nexus 7.
I just tried to reboot the device and also noticed the touchscreen performing a bit better. Though, the problem came back in no time, and after a couple of minutes using Google Maps was the same mess as before. Twisting/rotating the map with two fingers results to pinching/zooming and the map centers somewhere else you want it to. Also in Chrome zooming and scrolling doesn't work as expected, and selecting text is also problematic. Using the keyboard might get you a sticky backspace, which is somewhat annoying. I can only imagine how it would be to try to play touchscreen intensive games, which demand fast and precise touches.
On my Nexus 4 I've also noticed that Chrome seems to slow the whole device, and for this reason I've also been using Dolphin for a while now (but I've yet not deleted Chrome, I just don't use it). Maybe I should dump the whole app from my phone. Also using Clean Master to clean up the memory from apps/processes helps for a while, but only for a while.
Google (or Asus) could verify if there's a sw patch on the way. I'm not a gamer, I mostly use the tablet for surfing and reading, but also these task are not a pleasure with the touchscreen issue. If this problem still persist after a month or so, I really think about returning the device (I bought it just a week ago).
Chrome is super slow.
I don't know why but the stock Android Browser is super fast and awesome. I've been using Next Browser since it is based on Stock Android Browser but the past 2 recent updates have really screwed it up where it is beyond usable. Once it gets resolved, Next is really awesome. It is like Stock on Steroids.
However, regarding touchscreen issues, DON'T GO LOOKING FOR PROBLEMS. If you aren't having issues, then just relax and enjoy your tablet. If your tablet was plagued with a quirky touchscreen driver, then you would notice it. If you can't notice any issues, then you don't have any issues.
Sure there are tests you can run but why bother? It is a software problem and will be fixed eventually. This is not the first Nexus with quirky touchscreen drivers. In fact almost all of my Nexus devices had quirky touchscreen issues out of the box. All were corrected within a few updates. Even the Nexus One had a physical hardware problem with crossing axis that was alleviated using some Google Magic.
May,
I have the exact same issue--but my missed touches are once every 5 minutes--quite annoying when typing an email or typing a password. I haven't unlocked the tablet yet to apply sfhub's fixes--will let you know how it goes.

Stock android is fast but how do you get it with stock rom? chrome replaces it in 4.3 isnt it? OR are you on a custom?
I think the reality is that many are having problems but do not know about it. They may just dismiss it as not being accurate with their own touches. Also for some users, it could likely be their first touch devices and have no prior experiences to compare with. When i've gotten this device, it was working well and all, but it just feels like typing aint that smooth and slowly over time, the problems starts to be more frequent.
There was an incident i had when after a few days of usage, i tried using it with it lying on the bed and it was going crazy - which never happened before. I picked it up (attempt to earth it) and lay it back down again but the results are the same. So i did a reboot with the system on the bed, and all the problems went away. So i'm not sure it has to do with the earthing factor which many are citing.
I think it is a combination of GPU/CPU/memory and touch related event handling factors that causes the problems to occur more frequently after extensive usage. There should be no reason for hardware to perform perfectly after a reboot only to fail over time.
Oh well, only time will tell when these problems would eventually be addressed.

I guess you mean the stock android browser. It may not be available as an app but it's still there as a WebView component available to developers. I guess Dolphin and many other 3rd party browsers are based on the WebView component or on the source code of it.
The problem with the so called stock browser and WebView is that is uses some legacy HTML and JS engine that has not been updated since 2010 or so. That is another crappy developer "feature" from Google that for 3rd party developers there's no "web browser" component that is based on some up to date rendering engine like Chrome's.
In the Themes and Apps thread, there is a method to allow you to install the stock Browser on a stock rom without being rooted.
Also using Sfhub ts10 gave me a 90% fix but it would still spaz out occasionally and would miss touches or click weird stuff. ts20 really fixed me up right. I can play games now and type with no errors.
ts10 is a really good fix, but ts20 really hit it home.
