iPhone 4s keeps disconnecting/connecting at the slightest touch?

[KSaebin]

When I charge my phone with the USB charger (with my laptop, not a wall socket), it keeps disconnecting at the slightest touch and reconnecting again. It's so annoying but i don't know where the problem is! Is it a loose connection in the dock or something?

I got the phone maybe around a week ago, and the problem started yesterday.
What seems to be the problem?

edit: if it helps, iTunes gave me this error code when the phone many times in a row while it was trying to sync it.: 0xE8000001

Try an alternative cable first to see if a wire inside is cracked or loose.

If the issue is not present when you use a wall charger then the dock connector must be ok.

Maybe its the usb on your computer !
