It needs a lot more pressing strength to make it work than on my Galaxy Nexus.
I already heard this is a common problem, but:
I feel and hear a "click" from the button. With light pressure it is clicking but the button not responding - means the screen is not turning on.
When pressing harder (beyond the click) the screen goes on.
Is it possible that there is dust under the button?
Can this be repaired by disassembling the phone and cleaning a little bit?
Or do I have to change the button to get it back working properly?
