Question Static noise - Samsung Galaxy A52 4G

Hi guys, I experience this small annoyance on my A52...
Everytime I unlock my phone or everytime I start typing, there comes a short static noise (hiss) from the bottom speaker as well as from the upper microphone.
Does anyone have some idea what may cause this phenomenon?
Thank you all!

microphone / noise filer

Hello guys,
I was wondering, if there is application for monitoring the microphone sensitivity. Or even better, if I could through registry check the microphone level.
I am thinking of writing a small script (mortscript), that would check the microphone sensitivity, and upon some change would make a call. To understand, I am thinking of some small script to be as the babymonitor, or some kind of noise alarm.
Any ideas?
Thank you, mt

Speakers problem

I was unable finding anything about this problem so I decided to ask you guys here. So the thing is that my top speaker is louder than my bottom one. For example when I watch movies/videos in landscape mode I can always hear the sound coming from the left (top) speaker louder than the right (bottom) one. It's as if there is a small subbuffer integrated to it or something. By the way if I watch movies or some clips on youtube and decide to turn the phone clockwise even though the top speaker is located on the right and the bottom one - on the left, the audio is always like this top=left and bottom=right, so I can't decide wether or not it's a software or a hardware issue. So is this a normal problem? Is it possible that you guys have it but dont notice it? Is it a software or a hardware malfunction? Is it fixable?

In-call noise problem

Hello, has anyone got issues with this phone when calling? Sometimes, when I am in a call, the person who I am talking to reports that he/she can barely hear me and that there are noises from my side. I tested this and it's true, even in a quiet environment there are noises from my side, and if I cover then uncover for a few times the two mics on the top and bottom the problem dissappears but reappears after some time. I think this is a problem with the noise-canceling mic so I searched in the menu but couldn't find any option to deactivate it. I already did a full wipe and this is not a solution, the problem is still there. Any help?

Voice Echo During Call (The other person experiencing)

I'm encountering an annoying issue. During call conversation, the other end will hear their voices back (echoing). There's also a problem during video call (Facebook Video call), no sound will produce. Most of the issues I browse in Google were pointing to "Noise Cancellation/Noise Reduction/Noise Suppression", but unfortunately, the Xperia Z5 Noise Cancellation is "ON" by default and can't be turned off. I'm also thinking this is the issue.
What I did so far:
1) Safe Mode = not working
2) PC Companion Repair = not working
3) Reformat = not working
it might be a hardware or the build number/firmware.
Update: I've updated to Nougat today but still the Echo during phone call is still here.
have you replaced your screen ? i have, and i had the same problem. it was not faulty microphone but it was glued on the original display and not on the second. there was a small gap in there. fixed by gluing carefully back so that the hole was not covered! did bought anoither microphone but was not needed

speaker channel imbalance

Does anyone else experience an imbalance of voices between left (earpiece) and right (bottom speaker) channel when watching videos in landscape? It's really strange because first you hear the voice from the main bottom speaker and half a second later it's hissing out of the earpiece which is really disturbing.
Is it maybe fixable in the kernel or is it possible given the crap quality of the earpiece to disable it all together as clearly 95% of the sound comes from the bottom speaker? Maybe by you? @Freak07
Kind regards
