Hi,
One of my partner is asking a way to install an apk file and use camera application without an installed SD card since there is 8G storage already. But neighter they can install their apk nor can use camera app without it. Also it's not allowed to download anyfile without an SD card
 
TC55 is not like this. My Samsung too. I can select the storage area.
There is a line on MC67 user guide that SD card would be necessary but I still wish to ask  how they can switch the storage area to internal flash.

I also can't see if their application is trying to install itself to SD card or not. I'm sharing the app if somebody can interest.

thanks in advance
