To make it short, there is a shortage:
The cards are minimal thicker and harder to get something from the card reader.
In the camera (Nikon 510 and the Leica V-Lux2) there were no problems with it.
On the problem of all the SD - card.
If the backup to use lever once no longer walk many cards.
Right ... inserting and removing the card is moved each time the lever minimal, but that's enough to put the card inoperable.
The only remedy: Unlock the card and secure it with a tiny droplet of superglue the safety lever.
No use of scotch tape is stripped and then hanging in the Camera
