    i'm having problems with my phone when it's connected to the USB. the touchscreen response goes crazy. I can't even type an SMS message properly. I'm only getting this issue when its connected via USB. No issue if its connected with the OEM charger. USB connector is also OEM by the way and new so i gues its not defective

    Electrical interference perhaps? Try to use better/shielded USB cable or try in other PC/laptop.

    I have similar problem regardless on USB cable connection. Simptoms are that touch screen is not responsive, only midle button is working right. On screen I can see random actions like opening calculator and typing 7777777.8888 or something similar, but without touching the phone !! Then again, for couple of days whone works just fine. I don't know what to do.

    I've had a similar experience with the USB connection too. I think SashiX is right. Try a different cable, or a different port.

    Actually its normal... see in user guide book.. it say "While the device is charging, the touch screen may not function due to an unstable power supply. If
    this happens, unplug the travel adapter from the
    device." ... so if we use usb port to connect anything that can produce electricity also get same problem because of unstable power supply..
