The button on top stopped functioning and lost its "click".
I ordered a replacement and took the phone apart following the instructions. I found that the button itself wasn't the problem. I need the button cable with the replacement flex. That's the actual button that provides the click sensation. I reassembled the phone until the new part arrives and other than the button, it still works fine. More to come.
Take your time and label each screw with the step number. It'll make putting it back together much less frustrating with the screws of different lengths and sizes. Also, as I reassembled the phone, I cleaned with isopropyl alchohol to clean my finger's oil residue off connectors, cables and components.
