Hi, I recently installed X5 Mini Kitkat 2.4.0 (on an X5 mini), followed by the Metro launcher as provided earlier in this post. All is great...except the "app killer" does not actually do anything. Is there something I can do to make this feature work correctly. I guess I could install an after market app killer, but would it be possible to link it to the app killer button on the Metro Launcher? Thanks in advance.
