Welcome...yes, this phone has some bugs.
The message light bug is the following: there is an LED indicator at the top of the phone. As with most WinMo phones, you can set it to blink when you receive an email, voicemail, text message, etc. It blinks pink, though I suppose Samsung would call it purple. At any rate, the problem with the Intrepid is typically the moment the phone goes into low power suspend mode, the light stops blinking (or anywhere from 3 to 30 seconds after suspend). So the message indicator is useless, and you have to actually turn on the phone to see if you have any notifications.
Then to top it off the new WM6.5 lock notification screen is broken on the Intrepid - it will show VM/email, etc. but that indicator will disappear within a second or so, which it is not supposed to do. On HTC lock screens you can tap the lock icon to bring up a sub-menu and slide the submenu items to go directly to that item (like call voicemail or open the SMS messaging account).
