Dunked in water in pocket for a moment. Had Otter case so thought maybe ok. Initially was fine, then sputtering – (Re-setting Network would bring it back, but would kick me off shortly. Eventually nothing, now greyed-out NO WIFI always.) Decided to try Isopropyl Alocohol wipe-down of circuit board.
Also had dimmed screen issue for a while but this fixed itself. Whew.
Incidentally, coinciding with water dunk was fix update of OS. Uncertain if this was the culprit or not. Too many variables.
No luck. Still greyed-out wifi. Uncertain of how much alcohol to use: totally drench or sparingly dab?
The step-by-step guides were nice. Combined with vids and such from other sites, felt very comfortable going through the process. One wish: If the screwdriver were magnetized (which it wasn't), would have been much easier to get the little screws into the slots. Also was a product from retail hardware store (Do It Best) with a store right in town. Duh. But delivery came swiftly and conveniently. Thanks.
