This is also an annoying points. The plug moves too much, suddenly we always groping to put his camera. Where a risk of damaging the plug usb his smartphone or tablet.
But the point that was unacceptable to me is that I have to ask my Smartphone backwards! Placed on the dock, it's the shell that I have before me. So I do not know if it's my Smartphone (Baunz iota) that does not meet certain standards, or if this is a common phenomenon. but in my case it is unusable.
FYI, on the dock, it is the widest part of the micro USB plug which is at the bottom. Check your device.
If your device has the IQ technology (induction charging no connection), you should choose a suitable charger, it is more convenient.
