Digital Camera (e.g. HappiCAMU) and related product which should be support 16GB only

Although those product claims that they support 32GB in maximum, but I made one unit broken and another one failed to power on after using two different 32GB card and after using few days…I suspect it is not support 32GB due to it already show 9999 available picture after several shots or even take a video. It is by calculation, the number should be over 9999. Beside, when I insert a 16GB card, it show 86xx available.
