Volume key fell off on s21 ultra

[Mnich-zako]

Does any one know how to fit or replace volume key as it fell of? I've ordered new replacement one, but it won't fit. In the volume key socket there are still rubber buttons, just that silver key is missing.

@Mnich-zako: If the Volume button on the side of your Galaxy S21 Ultra has fallen off, then I strongly recommend that you reach out to our Help Desk to arrange for a Samsung engineer to inspect and repair the device for you. Attempting to re-attach an unauthorised, third party button to the phone yourself will void your warranty, and may lead to further problems down the line if not done correctly. If you're based in the UK then please follow the link below to find the relevant support channels. Otherwise, please let me know where you're based, and I will point you in the right direction.

Indeed, it won't from the outside. You need to do as Andrew said because the button is meant to be fitted inside the phone to poke through the hole. If you try jamming the one you bought into the phone you can do more damage to the circuit board
