Middle finger to the middle button

Of all the lamest thing to happen, the middle button for pushing "Enter" actually came off from my handphone. So now I have difficulty unlocking my phone, sending messages and I actually have to use a narrow pointed object to depress the button, leading to accidental deletion of 2 messages at once. My fat chubby fingers just don't really do the trick well. Time to leave long fingernails to actually reach the button. Or maybe it's high time to change a phone that has been with me for...eh...5 years?
