I have recently purchased the HTC sensation since three days ago and it is having the operating system of Android 2.3.3 Gingerbread and I am feeling so lucky to get the Smartphone. And there is the problem in the Smartphone I want the application that will turn off the notification and will turn on the ringer and Alarm but I was not able to do this I also want an application that set a "blackout block of time". And in this case it will turn off the email and the text and other notifications but the Alarm will be ON. Please help me in solving the problem. Thanking all in advanced for helping me.
