iPhone XR earpiece speaker problem
I have purchased an iPhone XR in January and it was brand new.
Three days ago I started noticing that my top speaker's quality had decreased , and today the top earpiece speaker sounds like it's covered with a finger. It's very quiet and muffled, the bass sounds are also distorted.
I checked all the responses to this, and nothing worked, and I hadn't done any damage to it, nor water neither any dropping.
Does anyone have any idea?
iPhone XR, iOS 12
