I had purchased Nokia 6.1 Plus via Flipkart and have received on 15 of October 18.
While playing songs and videos via earphone the sound is not clear, even tried 2-3 different earphone but the result was same.
I had raised return request under 10 days return policy offered by flipkart, they sent their technician and he couldn't cough fault. And they cancelled my return request.
I went to Nokia service centre and ask them to resolve the issue. They noticed the problem but he said all Nokia 6.1 plus are same.
I requested him to restore the software, maybe it works...
It worked and I was satisfied but after 3 4 hours again I faced the same issue.
It's a software related problem I guess. Nokia I request you to please fix this issue with software update or replace my handset.
