I've been having issues with the sound quality on my galaxy A54. Tried to fix it through Samsung online customer service but it didn't get better so they told me to go to Samsung service center. Went in, they said the speaker needs to be replaced and they have to order the part. So I went back once the part came in, the problem didn't resolve and now they're saying it's the motherboard issue. Of course, they don't have the part so it's going to take weeks again and I'll have to back-up all my data. Tried to get a replacement instead and Samsung customer service says I have to mail my phone for them to see if they can give me a replacement. And no loaner phones. Very disappointed, no wonder people don't buy galaxy.
