[Q] Speaker grill hole and Sound quality problems - One (M8) Q&A, Help & Troubleshooting

Hi Everybody,
is anyone else noticing the speaker grill hole aren't completely drilled through?
Also,
much more importantly,
is anyone else hearing a metallic grating noise when sound is played through the speakers? This isn't just high volume distortion, its constantly present even at low volumes. Very shrill, ratchety, and really annoying. Hoping to return and get a new unit if I'm not the only one with these problems.

I can't speak to the noise you're talking about, but the speakers not being drilled all the way through has been discussed several times before. The speakers don't go all the way across, so there's no need for the holes to be drilled all the way through. The extra holes are just cosmetic.

[Q] Buzzing sound from ear piece on a call

Hi
I recently got a Dinc2 as a replacement for my previous, crappy phone and I love it a lot! Much better than my previous phone. However, only one thing disappoints me slightly.
I hear a sort of buzzing sound from the ear piece when someone speaks when I make a call. Is that normal or a common/known issue with the Droid Incredible 2? Also, I think (though I am not sure) that sometimes this buzzing sound is less and sometimes more. I think if I hold the phone differently or gently the issue is less pronounced.
Is there any fix for this? I dunno if I am being overly picky with the sound quality but I'd like to eliminate this buzzing sound.
Thanks for your help, in advance.

Cause of haptic feedback rattle found

In my particular case, the camera is the culprit. It seems that the black piece inside the metal square chassis rattles when you tap it. When the vibration motor is active, it rattles the camera inside. Just sharing since it seems this issue has popped up a couple times.
Only solution I can think is to take out the black camera piece from the chassis and maybe stuff it a little tighter or order a new replacement, but the camera could be made that way. I'll take it apart again later today to see if there is some space for small paper or something to keep it still.
I've been getting this rattle for awhile now and was wondering what it was. Between the touch screen and bootloop, this is the third strike.
I also have a sound from the sound vibration motor, but its not so much a rattle sound, more of a beeping/squealing sound. Is this normal? Its not very loud but it annoys me when typing in a quiet room. Remember I had the exact same sound on my last LG phone so maybe its an engineering thing or the brand of vibration motor.

I noticed this on the forums too. I listened for this but couldn't find it. If I put my ear really close to the motor I heard a small whine, but it seemed like it was something else rather than the motor because it was constant. I will say the rattle could sound higher pitched to others depending on movement. My sound is a small rattle but I could see how maybe it could vary to a squeaking or squealing noise to some.

The camera has Optical Image Stabilization. Packing the gaps will stop this working. The rattling is just the camera moving around.

Did you listen to the sound in my video? You have that to? Its mostly when using haptic feedback on home and back buttons and the third button down at the bottom

Stereo Speakers

https://photos.app.goo.gl/jM0jiUfANc4KR64k2
So from the video it's hard to hear which speaker but you can easily hear the change. Basically what's happening is when listening to music or watching a video audio comes through both speakers. However, when you get a notification all audio stops briefly while it switches to just the bottom speaker, and then stops briefly again to switch back to both speakers. Once it switches to the bottom speaker it gets quieter and audio sounds noticably worse. And if you get multiple notifications at just the right intervals it creates a very choppy listening experience. I don't know if this is intentional or not but I find it very annoying and it makes it feel like the speakers were and afterthought. Also, why do speakerphone calls still come out of the bottom speaker? Why does it not do both like music or videos?
If someone created stereo alert sounds, would it maybe be an easy fix for the contrast in volume and mono source? Basically be a less stark a contrast? Same sound through both speakers on top of the music in the background.
Totally different topic, but somewhat related - I was going through online reviews today and I think a CNET video mentioned that someone determined the top speaker is tuned to 10 db less than the bottom. They basically ran left the same sound through the "left" speaker and then right. And by using another phone and a decibel meter app showed the top is quieter. Then they said something like when the engineers were tuning the audio, when both were balanced, there was distortion from the top speaker. But when both were balanced, but low enough that there was no distortion, it was too quiet. So they chose to go lower on top and higher on the bottom to have a better overall volume, without distortion. I wasn't listening so close so didn't catch if that was speculation on why or someone divulged that.
I searched later and couldn't find the original source, so it might be something someone just noticed.
Speakerphone coming through the bottom speaker is so some dumbass hole won't have it on speaker phone and hold it to their ear and get blasted in their ear and then try to sue Google

Bwahahahahaha...Very Nice!

Bottom speaker noticably louder than top speaker

I watch a lot of videos on YouTube of people reviewing things, and I noticed that voices sound louder and clearer through the bottom speaker, is this problem specific to my pixel 2 xl or do any of you have the same issue?

It is not specific to your phone.

Also the the top speaker is off when you receive a phone call( ringtone) and you will enable the speaker during a conversation. Why??

If I'm not mistaken, that goes back to before smartphones. Way back, there was a phone model that used the ear speaker for the ring and it was really loud. Actually rings in general used to be much louder than now, though there was a separate speaker for sound on most phones. There was some issue where people were trying to talk and having it ring right in their ear. I can't recall the exact issue, other than it was in the media.
So basically, they don't use the ear speaker for the ring so that people don't get a loud ring while they have their ear up to that speaker.

With my Nexus 6 this was not the case.. and I believe that it is very easy for a smartphone to understand and shift to the bottom one when you talk one the phone.
Well it isn't a legal requirement, just a design practice. Doesn't surprise me that a Chinese company would decide to do things differently. Proximity sensors weren't on phones until fairly recently.
It's weird as the quitet speaker on my device is the one below the navigation bar.

Vibration noise (buzz/hum) when making calls

Anyone experience a noise from the display speaker like a slight buzzing or hum during calls? It only seems to affect calls (not media) and only when my ear is positioned just above the exciter. MKBHD also mentioned this noise in his review. I went back to T-Mobile to listen to the floor model and it sounded clean. I also posted on reddit with other responding that their units had no noise. Unfortunately the store won't let me return it without charging me because none of the employees could hear the sound, or they said that it's too small an issue.

I've noticed the same thing, sometimes it sounds kind of like static, but the rest sounds like a mild buzzing. I only notice it some of the time on phone calls. Do you have a case on your phone as well? Might be worth taking the case off and see if it still happens.
