I'm having a bit of a whinge here. Not expecting a solution but feel I need to say something since I now have a very expensive wireless charger that won't hold my phone. I've had the Nokia CR-200 Wireless Car Holder for just over a year now. It is a very nicely made piece of equipment from the outside. It works pretty well most of the time though it has "let go" from the dashboard and plummeted to the floor a couple of times while the phone was in it (not a great situation).
Anyway I was driving this afternoon and my phone kept falling out. On closer inspection the grip arms weren't locking any more. A pretty critical feature some might say! I bought this thing in Australia and they aren't available to purchase in NZ and it is outside of warranty so I don't want to try for an international argument with whatever exists in Australia that might be comparable to the CGA in NZ. So I opened it up to see if it was repairable. So I find that there is a flimsy piece of plastic barely a millimetre thick that operates the "locking" mechanism and it has snapped off on one side and the remaining piece has split down the middle. Quite well broken.
I use a Lumia 920 phone (I can't live without Glance so i'm not upgrading to the 930) and I use the Nokia official silicon case that goes on it. It does make it more difficult for the holder to grip it (which surprised me from an official Nokia case) but with a firm grasp of the locking arms it did seem to hold. It turns out though that my firm grasp was probably putting the pathetic plastic lock piece under stress that seems to have eventually broken it.
Anyway up until today I raved about this wireless charging holder. It is a brilliant idea and makes charging my phone in the car such a breeze. I see after looking on Internet forums that this is a common problem with the units. Seems a bit of a shame that something that costs a premium can be let down by a tiny piece of plastic in the mechanism. If you have one of these handle it with care and hopefully it doesn't break like mine did. If you have one and it has suffered the same fate have you come up with a method to lock it?
