Mine wriggles but its not the usb jack, that doesnt move at all. Its the actual plug that is wriggling. I would say this is normal so you can wriggle it out. If it was to tight you would pull the whole thing out anyway. Last 6, IMEI - 685482
i'm going to grind down these two spring loaded clips on usb plug from charger. usb data cable is quite easy to go in and out but charger plug is bit different and you have to pull it fair bit harder to get it out. bit frustrating to have to do modifications like this on item that i didn't get from reject shop
