[AC Question]

I am using Note 4 over 2..3 months.. since a few days I have been facing a problem with the speakers..after listening to the music for about 20-30 minutes the speakers start with a cracking sound..and screen goes off

You could try doing a factory reset to see if that fixes the problem, though it does sound as though it may be more of a hardware issue. A factory reset would help determine that too though due to the fact that if it persists after, then you know it's hard related.
