Can someone come in handy, my solution to the problem Sticky keys without the involvement of the service center.
I warn you - I am not responsible for your actions, everything that you do - on your own risk.
Background: I have at the hands of white sgs3 Frenchman, assembly china. Of stocks - Strong Sticky power button and volume rocker slightly. Once again, seeing pover menu decided that the problem needs to be solved. The phone does not PCT and pay service while I'm not sure about the advisability of this very much did not want to.
So, need small Phillips screwdriver (ideally - hour, I was just so handy), stationery knife, and 10 minutes of free time.
1) Turn off the phone, remove the back cover, remove the battery, memory card and sim card. The last 2 it is important not to forget, because they tend to cling to the inner cover, which we will withdraw further, which could result in damage to their slots.
2) Twisted 9 screws fastening of the inner lid. In the image shown in red.
10th screw in the top of the phone, next to the headphone jack, do not touch it, it does not hurt.
3) Gently picks inner cover nail pull slightly on and pulls it out of the latches.
4) Now we come to the phone's internal phone and see the following picture:
Red marked power button. Pushing it from the inside with something suitable (I used a straightened paper clip) in the direction of the arrow button of the squeezing the phone. She sits quite tight, do not be afraid to push a bit harder.
5) A careful study of the very key to the part that the phone is recessed into the case paint showed nodules, which can be seen even in the pictures from the online store of spare parts:
6) Using a stationery knife carefully clean by these nodules. I did not "cut" and "scraping", I recommend to do the same, the button is quite thin, and it can be cut in half or just scratch the visible side.
7) Put the key in place, respecting the "polarity" - its sloping side faces the back of the phone. Check the operation of a pushbutton, if little remained stuck - can be similarly clean edge "window" in which it sits.
8) Putting the phone in the reverse order, rejoice the excellent work of a button.
Volume rocker was cured similarly small nodules were at the bottom. Personally, I have for 2 days no problem with buttons is not observed, and what you want.
Conclusion: The key sticky because of their small thickening in the part which is recessed into the body of the phone. When you click on it pinches, and the power of the inner part of the reverse action (the switch) is not enough to push the button back. Make small chamfer at its edges you can get rid of an unpleasant defect.
I hope this manual will help someone to save time and money on a hike in the SC.
