[huajijam]

qs tile seems broken,showing unavailable with a pinned language in some cases

maybe system overlay issues? no idea

When language tile is visible, it tries to bind service, if there is no pinned language set, or current running app is a system app or language selector, or bind fails, tile will become unavailable, needs investigation, but i think that is happening because bind service has failed, and there is no logic to rebind when that happen
