Currently having an issue with the fingerprint icon on the lock screen. Previously it always used to show every time when I woke up the phone and displayed on the lock screen.
Since the 5.1 update it doesn't always display, it's more like every 2 or 3 times waking the phone to the lock screen before it displays.
The fingerprint sensor works and I can still unlock the phone but it's just the icon that doesn't display which is annoying.
