I wouldn't even try to guess until you provide a reasonable amount of information about your situation. How do you expect us to narrow anything down without any clues?

Where is a sample video clip or even a decent description of the hiss? Tell us under what conditions this occurs, e.g. only on quiet environments, randomly, always, etc. Does it change when you change video quality settings, internal, external mike? What model phone, firmware version and anything else that appears even remotely relevant.

That seems to be a musical selection.. so how to tell what is part of the unknown music track and what is hiss? Better would have been recording the quietest environment you could find. Or if the hiss only shows up when recording something, then play a recorded music track. And provide both the phone recording and the original music track so that it can be, more or less, subtracted or distinguished from the hiss.

It would help if the track didn't have interfering music or if you tried recording in quiet, moderate, loud environments, impulse sounds, etc with comments on whether the hiss varies under various conditions. At a guess it's the aggressive ALC (auto level control) when you record with the internal (?) mike. So when there is a quiet part in the music, the ALC cranks up the gain and the noise from the phone circuit becomes more apparent. On that theory it would be good to know if using an external mike alleviates the problem or not.

If it is an ALC problem.. there isn't much that you can do about it.. other than consider using an external mike.. not recording in quiet locations, which could be difficult.. or hope that someone disassembles and tames the ALC.

I have the same problem. Even returned my phone to the service and they did smth to the mic, maybe even replaced it. But my problem is still there. Search for check out 'hissing 001' video on youtube, i have uploaded a sampleml. they said they tried recording videos with two other samsung fives, and they all had hissing problems. But i just cant accept that a quality phone like thos has an amateur error like this... for others, sound recording sounds just fine. What can I do?
