So I've been having a lot of problems with the power/lock button on my driod. It happened about 2 weeks ago, when I went to go shut my screen off, id tap the button, and the shut down/airplane mode/ silent mode would come up, everytime, and it would only work once in a blue moon, and id have to wait for it to time out. but now, the button won't even work!! I'll press it down as hard as possible, and nothing. it just won't work. and I'm not sure what to do about it. Please help!!
