According to 43Rumors, there is a new firmware update for the GX7. http://www.43rumors.com/new-gx7-firmware-update-released/ 43Rumors says the update fixes WiFi connection problems with Apple iOS devices and improves startup stability when using UHS-I compliant SD memory cards. To download the update, go to http://panasonic.jp/support/global/cs/dsc/download/fts/dl/gx7.html. I haven't tried this yet. Think I'll wait a bit to make sure there aren't any unintended issues.
