1. Type 0~5 and 7~9 for Calculator, make sure whether the other numbers can be inputed. (This is to check Calculator can do wht number input well or not)

2. Try 18/3 for example with Calculator (This is to check 6 can be displayed well or not)
3. Exit Calculator, dial a telephone number which contains 6 or try other applications (for example email/text/address...) to input number 6(This is to check key "6" works well or not outside of Calculator)

To isolate this issue we first need to find out the root cause of problem. If can happen that because of pressing same button over and over again with excess energy button is damage. If this is the then its not bug.

Perform a combination of the following tests in order to isolate the problem: 

1) Enter numbers 0-5 and 7-9 in the calculator application to determine whether other numbers fail to display.
2) Enter 30 / 5 in the calculator application to determine whether the number 6 is displayed. 
3) Send a text message that includes the number 6 to determine if other applications exhibit the same problem.  The problem may be a faulty button.
4) Place the previous software load back on the Blackberry and enter the number 6 to determine whether the calculator application still exhibits the problem.
5) Place the new software load on a different Blackberry of the same model and enter the number 6 in the calculator application to determine whether the problem is global.
