I talked about speaker issue being faced by some A71 users in their device in below post. And Samsumg service center claims that this issue is with mother board.
Today I went to one local mobile repair shop and got speaker replaced.
Speaker is working fine since then.
Whoever is facing similar issue in their A71, needs to get the speaker replaced if want to fix the issue. Neither it is software issue nor motherboard issue.
One of the user also got his device speaker replaced. Refer below post.
