Got a new 5s (space gray, 32GB, uk apple retail store) on launch day and have recently noticed the spirit level in the compass app is off by around 3 to 4 degrees on every axis. Went to apple store to ask about it and check on display units and every one of them had the same issue. Particularly evident when checking horizontally in landscape orientation. Staff acknowledged issue and suggested coming back in a month when they have more stock for a complete exchange/refund. Anyone else having the same problem?
