Mi 9T speaker issues - Redmi K20 / Xiaomi Mi 9T Questions & Answers

Hello.
My phone fell from a short distance by about 10cm. Since then, the main speaker makes strange noises when the sound is played. I replaced the speaker with a new one, but it is still the same. What could be wrong?
Here is the video of problem:

[Q] Samsung Galaxy A5 (2017) SM-A520F/DS speaker crackling/distortion

Hi guys,
I bought this phone two days ago and i think its a very good phone. One thing though, i find the speaker low volume, and when i try changing notification sound, some music gives a bit crackling/distorting sound.
then i try changing the Alarm, the title "Morning Flower" gives a bit crackling sound too.
Note that i only set the volume to 70%, and the crackling is already there.
I try the same music title on my friend Galaxy J7 prime, and his speaker does not produce any crackling sound and its louder.
The crackling sound only happen if i play piano sound or high pitch musics, but its strange with samsung default music it gives the crackling sound. Other normal non high pitch default songs plays good without crackling/ distortion.
Is it a known issue to this model or its just a speaker defect?
Thanks

Its for sure a defect bro i recommend getting it replaced.
*****NOTE*****:google search about the pixel soind bug and it had the same crackling problem as you said with A 2017 i use a pixel xl and after a few updates the pixel sound bug was solved by google so the main thing is that the cracling can be because of hardware or software but i recommend checking and replacing since it is costly phone. Also tell me the replacement unit has the same issue.

After comparing it 1 - 1 with demo unit on the store, i can confirm its the speaker defect. Demo unit sounds perfect with no crackling sound.
I have contacted samsung, and they have arranged a replacement unit in 3 weeks, i'll report back the result. :good:

Hello. I'm Korean
I have the same problem with the same model. (Korea SK Telecom SM-A520S)
Samsung Service Center says no such problem has been reported
Was the problem resolved after repairing the speakers?
I'm really annoyed by the problem I haven't experienced before....

Hi! I just got my replacement unit yesterday, and here as promised i report back the result.
I'm not asking samsung to repair it, i demand a replacement unit because i just bought it not even a week that day.
The replacement unit does not have such issue, my speaker is now running good no crackling and no distortion. I suggest you ask the SSC guy and compare it directly with demo units.
At first the samsung center representative also said the same, no such issues, he couldnt hear the crackling. But after i asked him to compare it directly with available demo units, he then realized there's some problem with the speaker.
I suggest you ask for a replacement unit. Good luck!

Buzzing sound from earpiece speaker

Hi,
I brought mi a1 2 days ago. While in call i am getting buzzing sound from earpiece speaker. Has anyone else ever faced this problem. If yes, I want to know the fix of this problem.
Thank you.

Distortion on earpiece

Hey guys! As I've updated my phone to Oreo (Jan) as soon as I got it, I don't know if this was an issue with Nougat, too, but the thing is that I'm getting distortion during calls. I would go for a faulty speaker, but sometimes sound is perfect, sometimes distorted, receiver test gives me perfectly clear sound, and sometimes only signal that it's ringing on the "other side" is distorted, but as soon as the other person answers voice is clear. This doesn't happen on loudspeaker or 3.5mm jack, though.
Any ideas what's the issue here?

M3 lite 10.1 external speaker crackling/distorting sound

Hi to all,
I just bought a M3 lite 10.1 and in some hours discovered an annoying defect that I please ask you to confirm or not in your device.
When music (from youyube or internal mp3) is playing on the internal 4 speakers at a medium to maximum volume and one try to close partially the holes' speakers (the lower or the upper one) the sound start to crackling like a distortion. It appears as a internal membrane starts to vibrate. If the speaker holes are free the problem doesn't appear. If the speaker holes are completely close the problem doesn't appear and the sound obviously doesn't output. The problem is more audible with music without drums like this:
Xxx.youtube.xxx/watch?v=inBKFMB-yPg&feature=share
This crackling/distortion is very annoing beacuse in landscape mode the tablet is always in position in which the 2 lower speaker are with the holes partially close... so the distorsion is inevitable.
I searched on all the forum but I did not read any about this specific problem on M3.
Anyone with the same problem? Any solution?
Thanks.
Can someone help me testing in his M3 lite 10.1 device if the defect above described appears with the video provided or similar with piano or guitar solo?
This could avoid to call the assistance if the problem appears on all M3 devices.
In the title I mean "internal 4 speakers"
Thanks a lot.

Front speaker audio issues

Hi guys, I'm having a problem with the Mi 9t front audio, whenever I hear audios on WhatsApp the sound gets echoed and a hiss, as if the sound burst.
The problem decreases slightly when activating mono audio.
Another problem is that WhatsApp audio starts loud and then decreases, can anyone help me?
Sorry for english, not my language.
Test your phone - go to settings, about phone, press core version few times
I bet it's related to radio version
Any news on this?
I'm facing the same issue on my 9T Pro.
Same problem here! Thinking in take back to he store that I bought and call warranty, but the bigest problem is that this don't appear all the time... My Mi 9 Pro is White.
