When my phone rings it start low then get louder ringtone is set to single tone. I was wondering if this is normal or not. The battery sucks. I have wifi turn off bluetooth turn off and so on I don't have any thing else running in the background I make sure all apps are close the only thing I have is my anit-virus software running. thanks. oh yeah when someone calls me sometimes the phone don't ring it go right to my voice mail.
