With my Edge 830 on beta firmware 3.33 I spotted a different behavior than my Edge 1000 does.
Don't know how it has been on 3.20 or will be with 3.50, just to mention.
For me Edge 1000 behavior is better.

Turn on backlight AND timer overlay So I have to tap again to remove timer overlay |

| Auto lap | Beeps but backlight NOT turned on | Beeps and backlight turned on |
For sharp bend warnings backlight turns on automatically.
