I couldn't reproduce this issue. I used three different devices: desktop PC, mobile phone and tablet, with different skins for each one of them. The result is a single cache file for each skin, so they never got mixed. Of course, these are local test, so maybe they are not 100% conclusive.
Maybe you should disable the default cache system ( http://b2evolution.net/man/collection-cache-settings ) for a while and look if the error disappear. How often do you notice it?
Do you use any other cache system besides the provided by b2evolution?
