Help android galaxy s2 phone power problem

[stunttt]

last two days my phone has been turning off randomly if i hold it a certain way. and if i push the power button it wont do anything, but it will do it itself alot if i have just a finger sometimes on the right side of the phone where the button is, dont know if i messed up the button some how it looks , fine, its just frustrating cuz when im in the middle of something it just turns off, im getting a new one in a week but is there any apps to disable your phone from turning off even if the power button thinks its hit? or a setting some where? any advice thank you
