After an accidental fall my volume down key with a little scuffing on the edge of the key feels stuck inside making it harder to click and sometimes when a click is successful it might remain pressed down until I press it back to get over the self click, I recently got this phone in the used market and don’t want to open it for this fix although I use assistive key but is there a way I could force such a key out without opening the device….pls I need your advice
