Backlight won't turn off after receiving SMS

[Guest oliie]

Hi all,

After receiving a SMS on my Touch HD the backlight turns on... then dims after a few minutes and remains this way indefinitely. This is annoying as SMSes that come in late night result in the phone being completely discharged by the tiem I get to it in the morning.

I have checked 'sounds and notification' settings and ensured that only 'vibrate' is checked for new SMSes. Every other notification is turned off.

Anyone else have this problem, or a solution? Would be greatly appreciated!!!

Cheers

Oliie
