Strange Screen problem.

This happens very intermittently. I my 4 weeks of ownership, it happened like 10 times. Today was the most annoying. Any item, program, window, application, I open, it automatically gets closed/minized, meaning "OK" button pressed on the touch screen. None of my clicks on the touchscreen get recognized. Is the screen bricked?
Any help would be great. I am planning to visit Cingular store tomorrow to swap for another handset and try my luck as the last resort before the 30 day window expires.

I also have this behaviour; sometime, when I am scrolling on my screen my device a "false" click on the close button and close the application.
It happen very very rarely, but it is still noticable.
I have no really solution; i just binded the voice button to the alt-tab function, when it happen I just press that button to get my windows back

Mine sometimes does this in PIE when I'm scrolling it suddenly minimises. Of course it helps also if you have a task manager that shows running programmes in task bar. It's then just a case of tapping the icon to bring it back again.
I think it happens because the screen sensitivity area goes slightly beyond the open programme window. So if it senses a tap off the right edge of the programme window it thinks you want the desktop. Why they make a screen that is sensitive even below the bezel is beyond me and is of course for the unlucky folk - the cause of the screen alignment problem

I am visiting the store now, will see how it goes. I thought this was a problem caused due to a magnetic case I used for a week the screen got distorted.

No - pretty certain it's not the magnetic case. Of course the magnetic case does operate the magnetic switch that operates when you open the keyboard. That's why it's often in landscape mode when you take it out of the case. This is annoying but the magnets are only operating the magnetic switch not interfering with the screen.

Where can I get that alt+tab function program?

Keypad + screen issues (after reassembling)

I took apart my tytn, including the screen part.
After reassembling it, I've had random issues related to the keypad and screen.
By keypad, I mean all the keys on the screen part of the phone (D-pad, call/hangup,soft left/right, Internet Explorer & Email).
They will randomly cease working and randomly restart working (usually after turn on/off the screen with the power button)
The screen will also randomly turn white and come back on only if I turn off the screen and then back on.
Im thinking it has to do with a loose connection somewhere in the screen section of the phone, however, Ive taken it apart 2 more times to check everything out and the problem persists.
I wonder if anyone experienced the same thing and found which specific internal is the issue.

i would like to know too cause my buttons just stopped working. so the talk, end, message, Internet explorer, ect. but the left down up right and center button work.

I have the exact same issue.
All the keys (not keybord keys) randomly stops working. I am so used to it now, that I dont even try to answer the phone with the green key button.
The screen fades to white, sometimes (maybe 1-3 times a day).
The screen is white when awakening from "sleep mode", turning on and off the screen fixes that after a while (50% of the time white screen when from sleep mode).
I have found out that putting a finger nail between the keyboard and the screen, on the right hand side, when in closed position, and then putting the screen back on, gives me a 99% chance of funktional display.
The problem also accurs in the "full keyboard position", But putting the finger nail in the same spot helps.
So I think the problem of the connection is in the keyboard part of the phone, since those slide contact always are on the right hand side, and the display contact shift side.
I would lite to know if any body have a permanent solution for this.
(I have now opend my phone yet, and I have tryed the putting thin plastic between the display and the cover, with minimal success)
thanks for your time

These are the exact symptoms of the "SCREEN FADING INTO WHITE" problem. See this thread for more info: http://forum.xda-developers.com/showthread.php?t=303872
The common causes for this are a bad connection to the D-PAD controller PCB (in the technical manual they mention it should be carefully checked and the really small screews with same torque making a 90 degree with the PCB), a bad controller (that was my case, had to order a new one) or not enough pressure on the square black chip on controller (some people seem to have fixed it by putting a plastic sheet in between the chip and the case, to apply constant pressure).
I suggest you try to re-open your phone and reconnect the D-PAD PCB as carefully as you can, double checking the connection and the screws there.
I did fix my problem, by ordering a new PCB and replacing the old (probably bad) one. It started to happen after I dropped my phone and it's the only thing that worked. Now my phone is as good as new.
Hope this helps!

Similar Issues with screen
I have similar issues;
Anything thats on the foreground gets closed by the 'x' button and if I slide it open the start button gets continually pressed!
Seems to be the top right corner of my TS thats at fault
sometimes it's fine....most of the time its not!
Andy.

I have the same! I have a huge dead spot in the middle of my (Tytn) screen, and if you tap there it actually activates the "ok" in the top right corner. The rest of the screen works ok. Whilst drawing in notes any drawing near the center dead spot results in a streak to the top right hand corner...
Bad screen?
Bad rom?
Bad motherboard?

You can rule out the ROM and M/board in my view for this specific problem. Your issue is very similar (and I think has the same cause) as those who find programs close randomly when in portrait mode and when they open the keyboard the start menu often pops up untapped.
I think this is just a case of a bit of pressure being put on the screen top right corner. Some folks have tried the business card run around under the bezel fix and had some success others have had to return for replacement/repair.
Some have taken the device apart and removed the gasket around the screen under the bezel, but this is not guaranteed to work.
Others have replaced the screen and for this particular problem it is very rarely successful as the screen is not normally damaged.
If you have a warranty use it - all of the above "fixes" are warranty voiding.

Hi Mike
It's an interesting problem as when performing a click and drag in Notes (drawing mode) the center section of the screen seems to work normally - a square box can select an area right through the middle of the screen - suggesting that the screen (as you say) is OK. So what is causing the a tap in the middle of the screen to register in the top right hand corner, when we now know that the center of the screen can work and respond in the correct manner. The size of the affected area is about the size of a thumb print EXACTLY in the middle. Personally I would like to believe that performing screen alignment 4 - 5 times a day for the past year has worn out the center dot and that is affecting the surrounding area. The trouble is that this fault has been reported on this site a few times now, and everyone says it's caused by something else! What did I do immediately before this happen I hear you ask? I flashed a new radio rom and was fiddling with a piece of card I have wedged down the RHS side of the screen to try and help stabilise the screen alignment. Since this problem arouse, I have removed the gasket - but that hasn't fixed it. I'm going to try and boot up the phone out of the casing to see what "zero" pressure applied to the screen does.
I'll report back...

It will be interesting to see what results you get. You'll need the old rubber band technique to hold the battery in place while you do it!

Well it's not due to the case squishing the sides of the screen as I just dismantled my hermes, wired it all up in bits on my desk, powered it up and still the screen has a dead spot in the middle and phantom taps in the top right. Temperature is normal room temp, approx 22deg c today.
I'm not sure the exact mechanisms of how these touch screens work out where you are tapping (resistance, voltage), but it looks like there are 3 separate strips running around the screen. 1 goes straight across the bottom, two goes up the LHS and across the top and 3 goes up the RHS. Therefore there is a gap between strips 2 and 3 in the top RH corner. Coincidence? hmmm It seems to me for it to register a tap in the top RH corner, strips 2 and 3 would register low voltages (or high resistance) and bottom wouldn't register at all. Thus suggesting a fault with the PSU that powers the touchscreen. Taps near the edges work because they are near the edges and therefore the resistance is not too great and can be detected, taps in the middle and worse off because they are far from all the detecting edge strips.
Does anyone think that there might a registry tweak for boasting power to the touchscreen?

Hermes Whie Screen Problem
To fix the "white screen" problem, you have to take your unit apart, and reconnect the ribbon cable.
I have a new 8525 and it started happeneing to me, so I took it apart this week, and reseated the ribbon connector.
Fixed the problem.

Has anyone here read and understood all that is said here:
http://msdn2.microsoft.com/en-US/library/aa919680.aspx

Perhaps someone could compare the touch.dll in Black Majik to WM5 - should be the same right?
How come that HKLM/hardware/devicemap/touch doesn't show the touch.dll driver as drivername? Keyboard has it's driver...microsoft says it should say drivername = touch.dll
Do you all have that in your registry?

Constant screen alignment problem

So since replacing my touch screen, I've noticed that the touch screen is having constant alignment problems. I read on another forum about a foam border going around the screen possibly causing problems and removed it and am still having problems.
When doing a test in the Notes function, it seems the more towards the center of the screen the stylus is, the more accurate it is. But when i start getting towards the corners, it either stops or freaks out.
Any ideas? Thanks!!

Poor touch recognition on screen corners

Am I the only one that seems to be having a major issue with this? It comes up more with the added on screen keyboard in 1.5, it seems.
The corners of the G1 screen do not respond to touch at all, and I find myself always having trouble hitting the keys on the corners of the virtual keyboard. Applications that require you to touch any corner of the screen with precision (ie tic-tac-toe) are annoying as well because it's difficult to get it to work.
Is there any fix in sight or is it a hardware limitation?

definitely a hardware limitation.

hardware limitation means: normal hardware limitation or limited due failure????

I only experience this problem with the right edge of my phone. The top, left, and bottom don't have any problems.
Touch also seems to be less sensitive when the phone is rested flat.

My phone has the sensitivity problem on the edges too (mostly on the right and top sides).
For example, it's almost impossible to drag an icon to the left screen, because it doesn't seem to reach the threshold area.
The protective screen (boxwave anti-glare) made the problem even worse, but since it's much more comfortable than the glass, I won't be taking it off.
The easiest way to test all this is to use the whiteboard application.
So, I ask the developers: Please don't place the buttons on the edges of the screen!
The worst apps in this regard I've seen so far were the Video player (don't remember its exact name, its seek slider was unusable), and the sudoku with the number chooser in the bottom. OpenHome's app slider has the same problem.

Edges of screen unresponsive (Unless touching bezel!)

This is my first phone with a capacitive screen, so perhaps it is a quirk of them, but I have noticed that if I am not holding the phone in such a way that I am touching the metal bezel, the screen does not recognise touches that are close to the edges of the screen. It seems that the screen requires a circuit to be made with other metal parts on the phone before recognising the touch.
For example, if I put the phone on my desk and touch the backspace key with a single finger, nothing happens. If I keep holding my finger on it, and touch the metal bezel, hey presto, the button clicks.
This reminds me of a watch a friend of mine had a long time ago, that had a capacitive "hair trigger" button that only worked for him (because it required a circuit to be made with the back face of the watch, meaning when he pressed the button it completed a circuit through his body)
Anyone else noticed this? It is slightly annoying because I have to hold the bezel when I want to use the phone..

Confirmed.
And you might very well be correct in the assumption about the circuit not closing in every part of the screen. I think it's the nature of any capacitive surface tbh. If you press in the middle of the screen then there is enough adjecent space to actually complete the circuit while on the edges there is simply not enough space around your fingertip to not close the circuit at all. That is why touching the bezel works.
But as I have been holding my little Hero in my hand while typing anything I simply didn't know this little odd thing. I have read about it though.
Yet another reason to hold your precious little Hero in your hand...

Wierd not like that on my samsung.. its all plastic tho

Mine is the same.. especially on the right hand side of the screen. If it's in a case it makes it really bad!!

Sounds like bad shileding and grounding to me

Didn't notice this until I put a screen protector on but now it's really bugging me.

On a related note (metal bezel related), I've noticed that in dim lighting the button backlight flickers. But if i touch the screen and bezel, it stops.

Same here. Could it be that the screen protector slightly touches the aluminium casing and thus grounding the screen (or creating a wrong potential)?
I noticed that when i touch (=ground) the outer aluminum frame with just one single finger then the touch screen works flawlessly.
(I'm using the offical HTC screen protector).

Hmm definatly bad grounding issue. Its either some pretty poor design or a defect.

i confrim, using hero without touch the metal edge result in less responsivity and difficult on multitouch operation
hope new firmware can solve this, too many errors using it like a normal keyboard on a table!
