Screen Calibration - Vibrant General

On my G1 there was a menu setting for re-calibrating your touch screen matrix. I have not found that settings page on my Vibrant. I think I may have a faulty phone, cause when I'm charging my phone and try using the XDA App, I scroll the screen a little, and it takes off at high speed to the end of the posts. It does this only while charging. Playing games while charging is nearly impossible, as I hit one spot on my screen, and it triggers a whole other area. Sims 3 is a really good one for it to mess with me. Is anyone else having these probs? I just want to know if it is hardware or software related.

You have to use a better charger. The cheaper chargers tend to do these with touch phones.

Coming from an iphone, there does seem to be a slight difference in terms of the area on the screen my fingers activate. On the iphone, a touch registers slightly higher up on the screen than the Vibrant. I suspect that Apple raised the area of activation on the screen in order to compensate for the fact that the pad of your finger is lower than the area just under the tip of your finger so that it would feel more as if you are pointing to the link and not have to worry about making contact with the bottom of your finger. I hope that made sense. Now, on my Vibrant, I have to focus on raising my finger ever so slightly because I am constantly selecting the link below the one intended.

Um, not my problem. When charging, my phone will sense a touch up to 1 inch away from where I actually touch it. But when not charging, it works perfectly fine. I think it is a heat or magnetic field issue messing with my touch screen only during the charge cycle.

I use the charger that was included with the phone and it works fine.

[Discussion] DHD - Crappy digitizer

First off, I'm not a hater.
I'm a previous HD2 user and in no way an apple fanboy.
However, I cannot fail to notice how increadibly bad our touch experience is with our dhd's. For instance, when you move your finger sideways, you'll notice how choppy it is.
Also, for example when playing Gun Bros, you'll notice that you won't be able to aim properly. Also there, it is choppy. Instead of giving all 360° you'll find segments where it just jumps over, if you understand what I mean.
I tried playing it on my friends iPhone 4, and it worked perfectly there. Very accurate.
I guess I just wanted to write my anger off and see if anyone agrees with me that HTC could have done a better job on the touch. I suppose samsung has a better touch with their 60 hz (or is it 69 hz) digitizer?
I have no issues at all with digitizer, what would say is that gun bros is still in beta stage.
I play plenty of games and not once come across any issues.
Yeah I've noticed that too when I was drawing stuff on it, when moving finger diagonally in a straight line it creates like a wavy line. Pretty disappointing but oh well, you can never have a perfect device...
I'm still happy I bought it though, much better then my last phone.
EDIT: Here's a pic, I tried my best to make straight lines as slowly as possible.
I find the touch screen perfect with no glitches or jumps in any game or app
Could be the game or could be an issue with your rom and the game
Do you have it overclocked and without general bugs? Those could be causing it
Or a power hungry app in the background making the game seem to jump
Another thought is a screen protector, when I put mine on it seemed to be alot less responsive

It's definately not an issue with the game, as I see this everywhere. It is a matter of the digitizer.
Also I am running it stock right now.
To those that say their screen is working perfectly, try flipping through the home screens very slowly from left to right or the other way around, with your finger on the screen all the time, and let me know if it follows the finger perfectly or if it's a bit choppy, as compared to when you go up and down in the app drawer for instance. You'll see about 9-10 "chops". This, I've reproduced on 3 different DHDs.
i'm using a -android Revolution HD and have no problems with the screen, i was trying to do dose things with finger and the window is yust there where i first put my finger on, so i don't see the problem here.

That is exactly what im talking about. Vertically it works fine but horizontally it is choppy big time! hence you cannot get a straight diagonal.

Sent from my Desire HD using XDA App
There no reason to get flamed, we're merely stating the truth.
Surely, the dhd is a great device, but we shouldn't ignore the fact that even HD2 was smoother horizontally. The fact that a high end device cannot draw diagonals across the screen is simply crazy, seeing as it was possible with previous devices, and I cannot help to feel a bit ripped off from htc.
But before concluding too much, is there anyone that actually cannot reproduce this problem? If so, please post a picture where you can draw a diagonal (of course by moving your finger in a slow enough motion)

I tried to do this with a drawing app and I can make "straight" diagonal lines when using a swipe action. I can also recreate the sample posted by drawing the line slowly.
What this means for the digitizer, I will leave for others to pursue.

Yep, when drawing diagonally in a fast sweep motion the line is drawn correctly and when drawing slowly it becomes wavy.
I'm also interested if there's anyone not having this issue.
for me, fast would be straight and slow would be wavy...
It could be bad software. I read the LauncherPro thread here on XDA, and people are experiencing this choppy behavior on their Nexus S' and so on using LP.
Bad Sense coding? Might be. Can people with custom ROMs post their results?

Id say that when moving fast you exceed the 50 hz limit and not all the "reading points" are used.
But it might be software related, could anyone with CM7 try to reproduce this?

It is all about software, the digitizer itself is great. I have a touchscreen pen, and I can draw bullet straight lines with it, no matter how fast or slow.
Then when I put my thumb on the screen and draw, the result is wavy. Our devices just need better handling for large touch areas.

Hmm! He's right you know. If I press VERY lightly (so only the very tip of my finger is on the screen) I get a pretty straight diagonal - but if I press down with the pad of my thumb, it's got the steps in it.
Seems like it's having issues determining which point is actually the centre of the capacitance.

[Q]Frozen while charging

Has anybody else noticed that the tough screen doesn't respond well when it is charging and laying down? I really notice this when I'm laying in bed with it. It works fine in my hands but if I lay it flat on my bed it won't respond. It only does it when charging.
I'm a bit nervous to handle it with how small the connection is. Perhaps its the plush of the bed forcing the plug into an awkward position?
Sent from my Honey Moto using XDA Premium App
I have this issue with my G2, and I'm sure other people have the same issue. Its more than likely due to the fact that it is a capacitive touchscreen. Because of this, the screen responds to the electrical connection between your hand and the device. When the device is sitting on a table (aka you're not holding it) and you are only contacting it with the tip of your finger, the screen can possibly not make a solid enough of "connection" with you and your taps won't register as well.
My G2 screen is much less responsive when its flat on a table not being held. There was a bit of talk of this in the G2 forums. I believe this is probably true with any capacitive touch device.
I have had this issue on my droid incredible extremely bad. I even had it replaced 2 times, but everytime it was in the carmount it wouldn't respond.
I have a Droid X currently, and the screen is very unresponsive while I'm holding it if it is plugged into my pc. If I have it plugged into the normal charger, then I don't have this issue.
I'm still waiting on my Xoom, APO mail takes a while
I don't have this issue. Mine works great
Sent from my Xoom using Tapatalk
All of these suggestions are well and good. It works beautifully when I don't have it plugged in. The instant I plug it in and lay it down the touch screen stops responding. I can lay it down unplugged, and it responds as expected. I noticed that if I make contact with the bezel with one of my fingers the touch screen responds. I am wondering if the charger is causing some kind of static charge on the device which messes with the touch screen. If I touch the bezel it grounds the device and allows the touch screen to work as expected.
Thoughts?
I bet anything it has to do with grounding issues...I hate ungrounded chargers. Have you tried this from some other power source? A coffee shop or work or even a different outlet?

I would get a cheap-o wiring problem detector from a hardware store.. you plug it it and it lights up if your house is wired wrong.
Have you tried it from a different source, like a friend's house? Or even a UPS that is unplugged from the wall.

Desire HD multitouch

Did anyone here notice problems with multi-touch when pressing with 4 fingers in a square.
It fails to recognize all fingers or misplaces them or other strange behaviour.
That means the screen is not REAL multi-touch and that's kinda disappointing in my opinion.
(4 fingers work fine in most situations, only when trying to achieve a perfectly aligned square)
Can anyone else try this? (best program to use is "Multitouch visible test" free from market.)
Works for me.

I've been testing this further today and it's slightly more complicated.
I noticed that when plugged into charger it seems to work, but as soon as I disconnect it the issue is back.
It also worked or didn't randomly through the day.
So I guess this could be a software issue, possibly to conserve battery..?

I can confirm that. Just tried it and it behaves very strange. Seems to me that it's not related to charging because both times I had my phone off the charger...
EDIT: OK I rebooted just to see if it's software related. It's not. It's purely hardware. You have to hold your phone to get proper multitouch. Simple as that.

Please remember that there are 4 different models of touch panel that HTC use in the Desire HD, 2 different screen models and 2 different camera modules. Not all DHDs are the same. If you have an ENG HBoot then you can see what hardware your DHD has by checking 'system info'.

Well I know about 2 different screens, and the Inspire 4G uses a slightly better camera, but I've never heard about 4 different touch panels being used
I also don't think it's a hardware issue, because then it wouldn't just work and then stop randomly. It really sounds like a software thing TBH

Hold the phone while testing the touchscreen. if you just leave it on the table, it behaves like you describe. If you hold it in your hand, the touches are precise.

If you get "Z-DeviceTest" app you can test almost everything... and our Display can recognize a maximum of 4 fingers, not more and not less, so its multitouch => Jazzhand XD^^
As others pointed out you need to hold the phone in your hand so your hand acts like a ground. And thats actually not really a problem since capacitive technology is supposed to be grounded if you want to make precise touch. Thats just basic electronic stuff we all should know

I have thought of that and I know how capacitive touch tech works.
That does make sense.
But then 4 touch shouldn't work at all when not plugged in or being held, instead only square position not working when not in contact, I mean 4 fingers is the same deal whatever way you position them on the screen?
Care to explain further?

Screen responding without touching it

Does anyone else have their screen respond without touching it?
I've noticed this in go sms. On the conversation list, the last one on the screen is sometimes pressed without me touching it. I will press back and it just goes back into it.
I recently noticed in web browsing too where the screen would refresh on its own. I clued in that the refresh button is on the bottom of the screen.
Seems like the bottom maybe 2 cm of the screen sometimes responds on its own.
Is there any app that I can see where the screen is being pressed?

The thing that bothered me today is that i was trying to press a button in the top left corner and the bottom link kept being pressed so I have to hit back and I was trying to beat the bottom press but I couldnt lol
I dont think there was any moisture on that part of the screen either
Yep, but not on this phone yet...
I say not yet because it's happened to me on almost every one of my touch screen phones. It seems to happen to me when the air is dry and I bet it has to do with there being more static electricity around. On those days when you're shocking everything you touch, those are the days when my phones seem to act up. It happened on my G1, my vibrant, Droid1, Droidx, and two of my bionics. All of the problems went away although on my 1st bionic it was really bad and almost completely unusable. The next day it was back to normal. Maybe it's just gremlins.
answer:
it happens if/when you use a DIFFERENT charger for the phone. you should be using the charger that comes with the phone. If you use a different charger (from a G1 or from a razr or something), then the screen tends to mess up, even when off the charger.

Is yours also happening towards the bottom of the screen?
For those of you with this problem, try pulling the battery out for a minute or two and also try touching something metal if you can. You know to discharge any static built up. (Worth a shot right) When I had this problem on my Sensation everyone was reporting that it was the charger they were using. I don't know if that was correct because the problem went away even though I was still using two different chargers. One charger was for the GNEX (same as GS3) and the other was the HTC charger. I really think it has to do with static electricity build up. If you think about the way these digitizers work it really makes sense. It seems to happen to me during spring time when it's dry and windy.

That is a good theory, but why would the static shock only be hitting the bottom part of the screen?
i don't know why. but i'm sure it's the charger. this happened back in the G1 days when android first came out. i did so many "experiments" with different chargers to figure out what was causing the screen to be all glitched like this. found out it was the charger. same thing happened with my vibrant, and same thing happened with my sisters sgs2.

Another touch issue, with reproducible steps

I know this is yet another touch issue thread, but this does not have to do with phantom touches, and differs slightly from another the touch/responsiveness thread in that I have reproducible steps. I actually posted this in the touch/responsiveness thread but I would like to get more visibility to see if this problem is universal, and maybe determine if it is a hardware issue or hopefully just a software/firmware issue. I can reproduce this without fail, as can my friend on his n7. Please try the following things and report back your results:
If I lay the tab flat on a table, unplugged, and touch it with 1 finger, touches are only registered maybe 70% (give or take 20% every 10 samples) of the time.
If I touch it with 2 or more fingers, no issues at all.
If I'm holding the tablet in one hand and touching it with 1 finger, no issues.
If I merely touch the case (not even the screen) with one finger while the tablet is flat on a table, and touch the screen with 1 finger, no issues.
If the tablet is plugged in, no issues at all in any scenario.
This sounds like a grounding issue, which I've experienced on other devices (my HTC Incredible had this I remember). It makes it difficult to use the device when you just want to check something while its lying on a desk without actually picking it up. I don't know whether firmware actually affects something like this (for example some code that controls what sort of capacitive requirements are necessary to register a touch).
I turned on
Show touches
Pointer location
in developer options
and performed your test.
I did 1 finger 15 times, 2 finger 15 times 3 finger 15 times
I tried with it flat on table and then separately holding (so basically 90 samples)
Every touch registered based on the output from "Show touches" and "Pointer location" against the backdrop of an empty home screen
I've had phones/tablets in the past where the touchscreen became a little spasdic when plugged in a charging but not when unplugged (not saying it isn't happening for you, just my experience)
this happens on a lot of devices when flat because you just dont press the screen as hard. especially when you are trying to just barely brush the screen. solution: touch a little bit harder, works 100 percent for me
Mine works great when I try this. No issues I can find.
[Update]
Meh Kinda iffy. Mostly works. Definitely missing a few touch inputs this way. Maybe 1/10 touches, but seems only in the top part of the screen close to the border. I've actually hit it 4 times in a row and got nothing.
I'm using Yet Another Multitouch Tester and using the paint portion and just tapping on the screen.
I have 100% tap rate when I hold it with one hand and tap with another. But if I lay it down on a desk and tap the top left/right corners, I'm getting misses. The rest of the edges and screen are perfect. I'm only seeing misses at the top corners really. The drop rate isn't enough to cause an issue and there may be other factors at play. I have Sidebar and Android Notification shades and CM10.2 kangs AppBar, listening for touch inputs on the edges. Something could be off with them stealing the inputs, maybe.
Or it could simply be something screwy with the screen. But oddly it works perfect with a second finger or a hand supporting it.
I think this is pretty normal, as said earlier. Capacitive touch screens work by detecting the electricity from your body, if the "circuit" isn't "good" (laying on wood) then it will have a harder time detecting touches. For me, it is well within range of acceptable. I almost NEVER use the tablet when it is laying down anyway. I can only think of a few things that would allow me to use it while laying down, handsfree, and if it misses once or twice, big deal.
I was laying in my bed last night trying to type a comment out but noticed that it kept missing letters even if i slammed my finger against the screen lol. Definitely noticeable too; not just 1/10 times. But I did put a spigen screen protector on there and if memory serves me right I didnt have any issues when a screen protecotr wasnt on it

I'm also having incredible difficulty in getting long presses to work properly (I would say on this tablet I trigger them every 2 out of 5 tries) which is a problem I've never had on another device.
I removed my screen protector and no more one finger on the table unresponsiveness..... Now the hunt to find a screen protector that doesn't block the grounding of my finger....

What brand caused the issue?
Intellishield which had never given me problems before got that brands on my s3 and had it on my hisense sero 7 tab as well.

Is that a wet or dry application?
I have the Asus official ones. I'm pretty sure all plastic ones will thwart electrical signals in some way. The only one that won't is that glass one.
Although the issue is such a rare occurrence that I can't justify spending another $20-$30 bucks to perfect. I'm pretty sure its normal.

Interesting.
I'm using the Illumishield dry apply ones. No issues here....
Screen protectors are unnecessary.... I never run screen protectors on these types of devices and never get scratches

Well the OP and you
I had the dry SP on.. so removed it.. and tried.. all fine. Tried with a New SP on. Still everything was A-OK.
My tab is a D60 batch or something.
