Thanks both.
But still not there. I went into Settings, More, Application Manager, All, and not there. S Note, and S Planner and S Planner Widget are there.
Also Sensor Services, which appeared to be running and com.sec.android.app.shealth and com.sec.android.service.health, both appeared to be running. But no S Health or it's widget.
It has really disappeared. Is my only option a full reset?
Thanks,
