Hallo Micha, hi Linuxx,
I discovered that you can easily "switch off" your camera by using some apps from the store ... like paper cam or pro hdr camera. After a reboot the normal camera app works again.
Maybe this was helpful...
it's now more than one month, that nothing has happened... the only thing I've seen so far is a new version for the MI-1
I really love that mod, maybe someone can tell "us" if you are working on a new version?
