The problem is long-standing Otto. It has come back to my mind with darker nights when I use astronomy apps (which depend on the compass for direction).
Thanks to all who responded. I think it is this app in this phone which is faulty - here's why I think that.
I restarted the phone after reading Otto's reply, and went down my garden well away from buildings, power sources etc. On calibration, the compass immediately indicated true north (with my hobbies, you know exactly the cardinal compass points in your own garden!) When I walked around, it abruptly swung 90 degrees to indicate east as true north, and stayed there. After a while it drifted about - as I swung east-west (i.e. following the sun direction), the needle moved AHEAD of me, not back. This compass app in this device is useless.
Thanks to those who replied

This is very odd. The compass supplied with my iPhone 6 plus is wrong by exactly 180 degrees. The GPS is fine and this is not due to interference as it is the same at any site. When calibrated as usual, by rolling the little ball around, the N point immediately swings to the south. There is no obvious means of rsetiing or adjusting it
