My volume buttons are not working

@samsunggal77268 this was left as an answer to a different Question. Let us know what exact model your phone is since the device it was previously posted to, is a A30s. For now we'll stick with that.

Anyhow, the volume buttons not working could be an issue with the mechanical button not properly engaging the switches on the flex cable. Most common is actually a faulty power button/volume switch flex cables.

Since iFixit does not yet have a guide for that, use something like this video Replacement flex cables are readily available at many online stores.

While you work on your phone, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has the same problem as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
