In addition to this problem, i have one more problem about sound, which is about the speakers volume. The top speaker seems to have more bass and highs being much louder than the bottom one that seems to be much more quiet and has more lows. In short, the top speaker is louder than the bottom speaker after Nougat Update. I've read the posts about Xperia Z5 which has the same problem and i tried most of the suggestions but i think that the source of the problem is the Nougat Update.
