回答“Which adhesive to use on subwoofer rubber surround”My directions for replacement of old foam surround with butyl rubber surround. (Do not use weldwood on foam! Foam will disintegrate) I use Weldwood contact cement. (Shoegoo is too thick for this application don't do it.) Peel top ring carefully as you will reuse. Keep all solvent and glue to only contact areas, do not leave any foam bits on cone. Peel old foam with care not to damage cone or tear spider below. most time old foam will just pull or rub off easy, I brush acetone carefully to melt the rest off. Pre brush clean at glue areas only with acetone, cone edge, basket ring then dry be sure to have removed old foam or rubber. IMPORTANT: Start with basket ring, then cone edge.

回答“Fast charging not working Galaxy Note 4”Yup changed the port and have two new bats, one direct from Samsung and one from Anker. Also use the fast charger that the phone came with and an Anker IQ3 "Qualcomm cert" batpak and Samsung factory car cords and charger. It's not going to help. OK, as many of you may have learned at this point there is a USB charge chip on the board backside left 2/3rds up that manages the "quick charging feature" that has failed. There is at least one example of someone replacing that IC and showing the fast charge feature working. ports, cords, chargers, no. This is a common issue on Note 4's. I love my 4 and still struggle with this issue but my solution was ditching the case and charging a second battery I keep in my EDC. Power save mode will get you charged still in 2.5 hours but regular speed charge will at best maintain the charge if your not using it full charging in 4 plus hours.
