Why won't my lock button work on my iPhone 4?

It looks normal an or isn't pushed in or hard to press, but It won't let me lock my phone or turn it off.

If my memory doesn't fail me, the iPhone4 has a manufacturing defect that the lock button will eventually break. It costs about a hundred dollars to fix not counting shipping. Sadly most of them break right after the warrenty expires. My friend uses an app for his iPhone 4 to lock and unlock his phone

  • Why won't my lock button on my IPhone 4 work? So, I came home today and my lock button wasn't working. Just wasn't working! It's stiff and it doesn't do anything. I tried holding in the home button but it goes to voice control? Ughh, what can I do?
  • Lock button on my iPhone won't work? I had just sent a text to my friend and I went to lock my phone but it wouldn't lock. I clicked it again and it gave me the option of turning it off. I turned it off but when I tried to turn it back on it wouldn't so I plugged it in to the computer and it turned on. My phone locks on its own for some reason. Is my lock button stuck or is it the whole phone? Any suggestions before I have to go to my mom about this?
  • My lock button does not work and my iphone 4 won't turn on My lock button does not work. And my iPhone randomly turned off. I tried pressing the lock button as hard as I can, but it still won't turn on. Before my phone turned off it was 73% . I tried plugging it into my laptop and I had no success. Are there any ways for it to turn on? Please and thank you. I also don't have time to go to the apple store.
  • My iPhone 4S lock button won't work? I'm really really worried. I just got my iPhone 4S for Christmas, and today I noticed it would take a minute for the lock button to work. I haven't dropped it and i have an otter box that never comes off. (I've tried to click without the otter box on and nada) I don't think I have insurance of my phone. (Not sure.) is there anything I can do? It's only 8 months old!
