Need help! Sinking power button!


Is a sinking power button caused by a damaged button or the plastic bracket? I have personally tried to replace 2 sets with this problem by just changing the button itself, but i could not get the button to work like it is before (Slightly higher, but still sinking).

So i was suspecting it could be a damaged bracket that was casing this instead? Some was saying it was due the loose metal bezel from the back casing?

Any idea?

Any pros can help?

Right, try again...I'm sure it said home button but there you go, I'm an idiot!

Power button...if it feels like it is sinking, and you've replaced the physical (outer) button, check you've got the right screws in. These are quite small, small headed screws, which I've got wrong before and had that sinking feeling. Make sure the silver loop on the inside of the frame (ie the back of the power button) is sitting on the ledge in the rear case(it acts like a spring and pushes the button back out again). If you've over tightened the screws generally it puts stress on those holes and it can crack and become loose (sinking feeling) . If you have only replaced the headphone/volume/power flex and still have the sinking feeling then I'd suggest your problem is the outer power switch has a crack in it.

Having a loose bezel/outer frame on the phone can also interfere..just put a bit of plastic friendly glue in the upper right corner and press frame and case together. I've only had this with replacement cases or dropped phones not general wear and tear.

Dear pollytinto,

Appreciate your response. Never thought it could be the housing issue but I have strip my phone to have a closer inspection again.

I noticed the grooves on the inner rear casing, where the 'handle' of the button suppose to sit on is quite worn. Also the housing there are cracks near the sim card area and im not sure it may indrectly caused it.

I have ordered a housing from ebay and probably will update after the swap

Hope it will solve the problem, thanks a lot.
