The situation is different at the unfortunately Samsung Galaxy S2 model with a Samsung Galaxy Note, where it was also tested. Here the plug wiggle extremely back and forth. A continuous charging, eg overnight is not possible because in a slight movement of the phone or cable connector is no longer sitting and therefore the device will stop charging.
My conclusion, for Sony and tested Cubot smartphones a really good alternative to the more expensive cables, for a Samsung device I would strongly advise against it.
