Quote from page 29 on the Nokia Lumia 820 user guide that comes in the box with the phone: "Use only compatible memory cards approved for use with this device. Incompatible cards may damage the card and the device and corrupt data stored on the card".
The guide doesn't list the "compatible" or "approved" cards for the device, or provide any insight on how to find them (well, there are a few links to www.nokia.com/support, however I haven't found a list of these cards on this site, just a bunch of people complaining about feeling ripped off for buying an incompatible MicroSD card).
Can anybody point me to this list if it exists or create it please? Preferably I would like somebody from Nokia to post an official list, however if anybody has bought a card that's working (or not working), please clearly indicate the model, brand, and perhaps model number of the card and whether it works or not with the Nokia Lumia 820 so a preliminary (and perhaps close to complete soon) list can be compiled.
I have just found out I was using a Class 10 SanDisk microsdhc card, and am concerned that I may have done damage to my phone and/or music collection (as per Nokia guidelines). Is anyone able to tell me what the chances are that this will have damaged them, and if there's anything I can do to rectify? Thanks!
