are you running android ics? In ics they changed the input slightly i heard, and maby its not ported correctly...

When using another music app or switching to generally other apps while music plays everything is okay?

I dont think its a virus or something, most of them want to spy or change userdata and not annoy you

I thought I had found the cause of my problem, but I can't confirm it, as this problem hasn't appeared since the middle of May, when I followed dertester12's advice to massage the screen on the corners!
But I noticed a spot in the middle of my touch screen where the "glass" seems to "touch" or to be glued to something underneath it. This spot is till here today, but despite of that, the problem is not occuring now. I'll try to attach photos of that.
So to sum it up, I'm still not sure about what caused the problem...

Did you disassemble your screen before?

Nope. You think something got under the touch screen?

I'll dig out the topic.

Hangsheng I have the same problem as described at the beginning, but mine handset had replaced touchscreen with lcd panel.
What it could be the cause of this behaviour?

Well the touchscreen must be isolated from the display. Therefore they put some blue glue at the area over the buttons where the HTC logo is. For me I used alcohol to clean the touchscreen as I replaced it and had the problem that when pressure was added the layer of glue was to thin to isolate and gave me fake inputs.

You can test by massaging this area.

Also the contacts on the backside of the screen must be isolated to the housing and the screen. I could think that when you soldered the stock isolation thinned out too..

Last but not least touchscreen, display and housing must be grounded correctly. Therefore all parts are wrapped in metallic foil at the edges... To connect them..

As the touch screen is very sensitive to even little currents its often hard to find the problem as it could also be a totally different cause.

All the above mentioned points should be checked and are relatively easy to fix. But it needs total disassembly what - especially to old devices- has a risk.

Risks are:
That damn flex cables are old and tend to break. The buttons have small tapes on top that come off easily and never go back again... And many more things that break when dis- and reassembled to often.


Sometimes it's cheaper to sell defect HD2 and buy new/used one..
On eBay you often get very good prices for defective HD2..

Default Odp: [Q] My HTC HD2 is going berserk

The thing is every issue dissappear when it's on WinMob. I cannot pass this behaviour so decided to switch handsets. HD2 was very good phone.
