    I have strange problem with my screen sensor: while I charge battery (but not always), sensor react to touch incorrectly... Pushes buttons that I didn't touch, or desktops change each other when I only touch screen. I don't know, return smartphone to shop, or it's program bug and can be fixed with new version of android? Current version is 2.3.3.

    I've noticed the same a couple of times - not bad enough to return phone imo though - don't know if other Droid phones have the same issue

    Just wondering, but are you using the original charger that came with your Wildfire S? If you are, do you have a friend that can lend you one to try out.

    The reason I ask is that I know that bad third party chargers can introduce electrical noise in to the system - noise that touch screens are very sensitive too and prevent them from registering touches correctly and makes them jittery. Perhaps you have a slightly dodgy charger - so would be interesting to hear if the problem still occurs when using a different one.

    Ben.

    Yes, I'm using original charger. I wrote to htc support, and they said the same: I need try another charger. In next week I will change charger to new, and will write about result.

    I am also having the exact same problem. Every time I charge my Wildfire S using the supplied charger whilst it is switched on the screen becomes jittery and does not respond correctly, making it unusable. The reason I have only just discovered this is that normally I only use the HTC charger to charge the phone when it is switched off - if I need to charge it during the day I plug it in to a spare USB port on my PC which does not cause any problems. Nor do I have any problems when charging using an in car charger - so I guess the issue lies with the HTC charger - it must be generating a lot of electrical interference. I'll drop HTC a line and see what they say.

    Ben.

    I'm already dropped a line to HTC and they say: "try to use different charger". Then I went to HTC after-sales service, where specialist try to charge my phone and... it work normally! (( And he said: you have "capacitive touch screen", so this is normal to HTC, it can work with this artefacts. At home this problem appears always... Maybe this depends from electricity voltage?

    P.S.: It seems, like touch screen work-ability also depends from hands temperature (or device temperature)... This is my first touch screen device, and I don't know, they are all work with this artifacts, or only HTC devices, or only my copy (

    Replace the charger....
    Test it on USB or any other chargers you have access to.

    I just resolved this issue with my Galaxy S2 LTE. The wall charger supplied with the phone was bunk.
    I took it to my rogers dealer and they gave me 25% off a new one after testing since they aren't covered by the manufacturer.
