This is most likely a basic question but I couldn't find a good answer in various threads (or bad searches) and it's driving me crazy-

My phone's dial screen will go blank when I make calls at what seems like random times unless I press a button and even then it sometimes doesn't bring it back. This is awkward when I call into places that require touch tone input like credit card companies...

I've seen this before with other ROM and guess it's inherent in the Tachi build. Is there a fix or work around?
