iPhone 8+ volume problem

[smitev60]

Ok so I bought an iPhone 8+ like 2 months ago and recently it started to set the volume to the max on its own i am not sure whats going on. Any advice how to fix this? (There isnt an Apple store in my country so going to an Apple store is not an option)

Try to factory reset via iTunes by flashing it also backup pictures and everything else.
If that doesnt help i guess its hardware failure.
If its under warranty take it back where you bought and explain them.
