Hi all, I have a Galaxy S6 that seems to be about 0.1db louder on the right channel than on the left. To test this, I did RMAA analysis and found that the frequency response curve on the right channel is 0.1db louder. Is this the right way to measure channel imbalance? (I tried using a multimeter but was unable to get a reading no matter what... perhaps someone can shed some light how to use a multimeter to measure?)
I know RMAA isn't that accurate without professional, calibrated equipment. But I tested numerous other phones using it and they were generally more or less balanced (0.05db at most). So I am a little shocked that the Galaxy S6 shows so much variation.
So I did a couple of tests on mono mode with several earphones and noticed many of them leaned to the right on the Galaxy S6 whereas they were more-or-less balanced with my other equipment... So my question is, is this placebo, or do I have such sensitive ears to be able to tell channel imbalance with just a 0.1db difference? Or is there some other relevant aspect in the RMAA analysis that I am neglecting?
It's a tough shot getting the phone replaced though; I doubt the service centre will care about my request. It also does seem like a common problem. One user on XDA measured his right channel louder by 0.1db as well (whereas his Note 4 measured in at around 0.05db); a Korean review put the left channel louder by about 0.1db.
Any thoughts?
