Can any S3 owners please confirm for me if all buttons on the outside of the phone, including the home and power buttons have a noticeable clicking sensation when they are pressed? There is even a very slight audible clicking noise when you hold the phone right beside your ear and press the button. Have purchased a S3 off of eBay and the home button acts more like a soft key/touch screen button, it has no tactile feedback whatsoever and no clicking sensation. My research and contact with samsung all points to this being a fault due to overuse, excessive pressure or water damage. The seller claims the phone is an as new warranty replacement (contrary to the scratches on the back).
S3 owner checking in - all my hardware buttons audibly click as they are pushed, along with tactile feedback as they go down.
Having purchased 11 Galaxy S3 mobile phones (not all for myself), I can confirm they all have the same style buttons which have a decent tactile feedback when pressed and have a audible click. The volume of the click is fairly faint, but if listening for it, you can hear it even if the phone isn't directly next to your ear. Edit: Worth adding that one of my phones is also a refurbished model and still has the buttons having the same tactile & audible feedback as the newer models.
Cheers guys. Thanks for the further confirmation. Seller has accepted a return and refund on the condition of a 'Samsung Approved Repairer' verifying the fault on his end. I give a 9/10 chance of them being muppets and saying this is how it is supposed to operate.
