htc My Touch 3g touch screen issue when charging.?

I know its weird, but this is whats going on. My Mt3g has a problem when it is charging on a 110v ac power supply. When charging this way the touch screen reacts erratically at best. When it is plugged in to my car, 12v dc or my computer, usb2.0 or my new 3.0, it works perfectly. I cannot describe why or what the difference is. I am looking for two things. If anyone else has this problem, and if anyone know why it does this. I have given up on fixing it, but it would be nice to know the difference from usb/car to wall outlet. If it was just the usb that was okay I would suggest it is the debugging option, but as it is, it makes less than no sense.

Thanks in advance

    That is because the power supply that you are using has too much voltage going into the phone. Meaning it's not an HTC AC charger. If it's a Blackberry charger or a Motorola charger, you will get those type of results.

    USB will work just fine, as that voltage is pretty much set but the USB connector on the computer.

    Nope it's not the debugging option in the settings. Car chargers are also regulated to not send too much voltage to devices.

    I'm pretty sure if you are using the wall charger from an older phone of yours or a borrowed wall charger, that you will find that getting one made for the phone will work MUCH better, without the touch screen weirdness or apps going nuts on their own. Left too long and you will either kill the phone or zap the battery, because the extra voltage can (sooner or later) override the circuitry that keeps the phone from over charging the battery. And if that happens, you can pretty much kiss one or both of them goodbye.

    heavily those human beings announcing Verizon are loopy . The plans and their fees are incredibly plenty ordinary. in case you get an iPhone, the plan is a hundred for internet and all that junk. comparable with Verizon and sprint. sprint demands purely each little thing Plans with telephones that have Android, and Palm telephones or Blackberries. I easily have had sprint for 9 years and Ive under no circumstances had themes with them. I easily have a kinfolk plan--that's 4 telephones; 2000 shared minutes (we dont use the telephone plenty), limitless internet, texting, archives (purely each little thing) for 179 a month---and we get a coupon, and our bill comes out to a hundred and sixty a month.4 telephones; for a hundred and sixty a month. Thats very much. The provider works everywhere. ATT has terrible provider, as does TMobile . i can work out why youre caught between Verizon and sprint, they're the wonderful. The DROID sucks! The keyboard is ridiculous. The Hero is perfection. between the wonderful telephones Ive seen by capacity of Android. the 2d by capacity of Samsung is likewise super. MY sister has it. I easily have Palm Pre and besides the actuality that human beings *****, that's easily an excellent telephone. execs approximately sprint, provider is super, instore rapid provider, reliable costs, reliable telephones...reliable provider. ALL is super
