Screen after call ends

[bb0bbby]

I am wondering if this is an issue on my phone or all. If I am on a call for longer than what the settings for the screen to turn off are, I am unable to hit 'end' due to the screen not lighting up. Is this occurring on all phones or just mine ?

I also had a problem on friday with not being able to hit my password for voicemail. the numbers would show up but not to my voicemail & it just kept asking for my password.
