In my program, I have a TextField that has its constraints set to PHONENUMBER. On some (all?) Series 40 devices, this enables the search function to be able to go through the phone's contact list on the SIM card in order to select a number.
However, occasionally, both I (on my Nokia 6610) and a tester (on a 7250) have had the phone's screen go black, and then the phone resets itself and goes back to the main phone screen on some occasions when selecting an entry in the phone book.
Has anyone else seen this behaviour? Will a firmware upgrade fix the problem? I am not comfortable releasing the program, knowing i'm likely to get a flood fo support requests because the phone crashes when people try to access this feature.
