Hi, I'm a big fan of the HD2 but in the last two weeks, since i own this device, i'm getting confused by some screen imput behavour that i will present you.

I want to figure out if this "screenbugs" i have to fight with every day, are normal or a hardwaredefect. To make you guys an imagine of what i mean, i uploaded some youtube videos for each bug.

1. The first one i call: The painting edge

This bug is only present if i not have installed the less sensitive CAB from this forum.

Many of you have notice that the glass of the screen doesn't fit exactly in the case of the device. The right bottom of the glass protrude a very little. Then i lightly press on this position, the screen notice a press on the right you can see in notes on my youtube video:

Video 1:


Beforce you device doesn't having any of the following bugs, REMEMBER, This bugs are not present every second. Sometimes i can use the device for 30min without having some of this.


2. The Electrocardiography

This bug, i think could be the reason for the following bugs.

Explaination: Trying to draw a straight line an you think you device will get a heart attack soon.

On the half of my second try you can see how the device suddenly works normal again.


3. The shaking Screen
I have notice that some other guys have this bug too. You can see this on every scrollable screen, like opera, IE, zoomed pictures, the manila tab, startmenu...etc. etc.

Best seen on minute 0:54 in my video.


4.The non pressed key
You are cofused about keyboard reaction while writing a text message? You type an "a" and getting a "t"? Than you have "the non pressed key" bug how i call it.

you have to watch on some key input where my finger is totally out of range. I don't mean the fault input next to the key i pressed...



There is a fifth bug i didn't get on video yet because it is very rarely.
I had have this bug only 5-6 times since i own this device, but it sucks realy hard.

I call it

5. The self-typing keyboard

Then i'm typing some text sometimes the keyboard begins to typing without having the finger one the touchscreen. it can be have a duration of 5-10 seconds or 20 letters/numbers.
It can also be watched, without keyboardaction. Then the screen scrolls wild in any direction without any finger on screen.

If someone can tell me if i can embed the youtube videos in this forum...

Go get a replacement, the screen is perfect. Although I admit it does not fit correctly but it is great. I only need the earpiece fix

...You're too much electrostatically charged...
...Or something of electrostatic is in the range of your device...

But it's like your touch panel is faulty. Get a replacement (warranty rules)

tryed all your test and get no errors on screen, electro worked perfecly, keyboard keeps presing same key without leaving the range, and i cant notice any shaking effect.

So probably your screen is faulty , change your device as fast as you can matte

I have brought it already back, but it seems to be that others have all my listed bugs too. take a look at the poll results. On another forum a guy has tested the "painting edge" on 3 devices after he saw my video and all devices have this bug!!!!

Hey Guys,

I have the first 3 bugs on my HD2, too. But with BSB Tweaks 1.31 i solved the first 2 one by activating the option "Screen Sensitivity".

If you look in the sticky thread here somewhere in the LEO section about tweaks and registry changes there is a topic on reducing the sensitivity of the screen.

I think what's happening here is the electric current in your fingers is playing havoc with the screen when your fingers are either close to or on the screen.

Let us know if this helps you.

whow, that's a lot of problems for one device.

I have the "non pressed key issue" : (that's annoying as hell, typing a message is a heavy burden now) and the shakey screen. should i bring my handset back or try the tweaks... I didn't expect this from an 600€ handset

When i was made this video my finger was always with the same pressure on the touchscreen. It was not close...and not weak on screen...normal pressure. And you can see at the middle of my second try where i'm drawing lines in notes that the screen suddenly works normal.

I also wrote in my first thread, that this bug is not every second present...but then it's present its also the reason for some other input errors, like the "non pressed key" i think.
