Electrostatic noise coming from the back - OnePlus 5 Questions & Answers

Hello guys,
Tonight I noticed something. When I am using my OP5, like while reading XDA or writing this, I can hear some kind of electrostatic noise coming from the back of OP5. I believe that is related with the CPU and that this is normal.
However I would like to know if someone else noticed this.
You have to be in a quiet room.

Nope, never heard any noise coming from my phone

I think OP has a Pixel 2 :laugh:

I can hear it at the top back of the phone when I place my ear against the flash. Though I don't believe it's the cpu you hear maybe it comes from the little mic placed between the flash and camera?

I can barely hear that noise only if I put the back side of my phone directly on my ear but is very very low, in real life use even in a really quiet environment I can't hear it at all

Volume muffled when set on a flat surface

I've noticed this issue without a case and with the Otterbox.
Ringtone volume is cut in half if it's sitting down on a flat surface. If it's propped up a bit, the volume gets twice as loud, making it easy to hear from another room.
Has anyone else noticed this and done something about it? Was thinking of trying to find something small to stick to the back of the phone that would raise it up a bit when it's set down.
It's just science. Pressing the speaker against a surface will always muffle it. But raising it slightly above a hard surface will cause the sound to reverberate off the surface and will make the volume sound louder.
I have a piece of velcro (the soft side) stuck to the back of my phone where the Google logo is that I use to mount the phone with in my car. It achieves the effect you desire perfectly.
That is because the ringtone sound comes from the speaker on the back of your phone. Cover it up and it is going to get lower. Put it on its face.

But, the OP is right that it will actually sound the loudest if you have it on it's back, slightly raised, so the sound is reverberating off the surface. And, if you are using it as a speakerphone, you will muffle the mic by laying it on it's face.
I personally wouldn't have added the velcro just for this reason, but it does come in handy when using speakerphone at my desk.
I can understand the science behind it. I didnt realize he was trying to achieve maximum sound, just that it was going quiet on him. Even with my Diamond, I used to cup my hand around the speaker to direct the sound at my face while I watched Youtube. Still use the technique with my Hero.
The flip side to this is that it seems to have much better sound quality when it's set down on a hard surface. Music sounds much better when my phone is sitting on my desk than when I pick it up or have it in my shirt pocket. Seems to have better bass when lying down, less "tinny" sounding. (Not that you're every going to get *amazing* sound out of such a tiny speaker, though.)

I thought my phone's speaker was broken!!! I wondered why after returning it 4 times, it still sounded muffled when I set it down.
Thanks for all this helpful information.

I have a little different problem. When I put my phone on silent mode, I can't hear the phone ring. Is there something wrong with my phone?
Ha ha, here is some more proverbial wood for the fire **wood**. Hopefully it is enough to keep the flame going.

I'd take it back to the Sprint store. Something's obviously messed up.
Am I high, or was there really an entire thread created to ask this question.

What I don't like about Galaxy Note

To be fair to all those considering Note, after all praising (I still do think it's best phone in the world right now), there are definitely drawbacks.
Here is one for example:
The regular phone speaker above the screen (not the loud one on the back) is not pointing sound into one direction. You can even speak on the phone with back side of Galaxy Note put to you ear, you will still be able to hear everything clearly, even on low volume.
On top volume, it is comparable to speaker phone on some other phones, so if you pick up a phone while surrounded by other people (unless you are in very loud place) they will hear the other person.
While in the office, I noticed myself turning volume down a lot when I pick up the phone.
I dont have this kind of problem , my old Nokia phone does.
Sure someone can hear some of the content near the phone you are talking in a dead silent arwa, it's inevitable.
I feel Gnote already perform quite well compare to the other phones, like HTCs in this area

to be honest id rather it was loud and have the ability to turn the volume down than it be too quiet and unable to turn the volume up
as my mum used to say,if its cold its better to have a coat and be able to take it off if you get hot than be cold and need a coat and not have one

It's not a question of whether badly working phone is better than no phone. It's a question of best phone being of high quality. In this case its potential privacy concern.
I switched from iPhones, where it was not an issue. If you put it tight to your ear in silent room, none else hears the person on the other end. Even on loud.
Like I've said above, on Note in silent room regular speaker (not the loud speaker) is comparable to loud speaker on some other phones. You can hear through the phone! Test yourself, make a call with screen side out, battery cover side to your ear, you might be surprised, that it's practically no difference what side you hold it to the ear, even on lowest in-call volume you can still comfortably speak with wrong side of the phone touching your ear.
I have not tried other Notes than mine, but I seriously doubt that it is one time occurrence, seems to me like an engineering issue, not enough sound insulation behind the speaker, just few thin layers of plastic.
If it is such a privacy concern, why not use a bluetooth headset or earbuds? Why not leave the room instead of taking the call in the room?
I mean there are more options that just sitting there letting everyone else hear your conversation if you feel that you have something to hide. But then again, your talking so they naturally are going to hear at least 1 part of the conversation no matter what. So I fail to see how you can really be concerned with privacy when they hear everything you say anyways, right?
If you were that worried about privacy you would send texts, emails or use an IM program to send messages so that no one knew what was being said or talked about. But since you are willing to sit in the room and let them listen to what at least you are saying, then you are not overly concerned with them at least hearing part of the conversation.
When I get a call that I dont want anyone else to hear I either leave the room, put on my earbuds or tell the person I will call them back when I can talk. So really it isnt about privacy concerns at all, it is just an inconvience for you to know that the speaker is loud. Louder than you are used to at least.
Fuuny that you mention this because i never thought i'll use those bt headsets until i own the Note. Each time i put it in my ear, my worry is not the volume but the number of heads turning towards me and the the sheepish grin that follows.

A damn proud Galaxy Note owner.
Maybe try turn down the volume and using a case.
I wonder how those HTC phones perform because they all have ear speakers that are wide across the width of the phone itself.

Lol..the speaker grill on HTC phone what we call it, is just a gimmick. If we see inside, the speaker none the less is only small portion on the middle side

[Q] For those with their Nexus 4, is the earpiece making a screeching noise?

If I place my Nexus 4 against my ear, I can hear high pitched screeching and some popping coming from the earpiece, even when a call is not taking place. At first I thought it was a heat issue, maybe some capacitors or something getting a bit hot and whistling, so I turned the phone off and the noises stopped instantly.
This is pretty annoying and surely shouldn't be happening
Yes, mine too

I'm glad you posted that, mine does it too - and I thought I had a faulty phone.
According to support I'm the first to report such a problem, have you called support about it? - 0800 328 6081.
The more of us that call, the better the chance it's sorted (if it's possible).
I can't live with that noise, it's too loud for me as I have sensitive hearing on interference like that.
So it looks like I'm sending mine back for a refund and go buy a S3
It does sound like poor build quality in suppressing electrical interference to the ear speaker, as you say capacitors or even a processor is leaking noise to that speaker in the same way cell/mobile radio causes to external speakers when brought close to them.
WOW so many problems already with this thing!!! I don't know about this phone right now

I returned it to the store for a refund - they refused to swap it for another as they couldn't hear it . I've ordered another which I should get tomorrow, and if that has the same issue I'm not sure what to do - it doesn't really sound like something that can be fixed through software, does it?
I asked on another forum and one person replied saying that there's was ok, but maybe they're ears just aren't as sensitive as ours.
I remember as a kid, I could hear CRT TVs from a long way off (no sound was coming through the speakers) and nobody else could.

I think you're right, I too always heard a CRT working (I still can when I see one working!)
Maybe we're hearing interference the average user is not going to hear.
If anyone else is reading this and owns a Nexus 4, try calling your voicemail (which I assume would be free for you) - during the call wait for a few seconds and listen carefully, it's more obvious when you're not talking and in a call.
The noise is almost like having a small fly trapped between the phone and your ear at times, it also reminds me of the noise a hard drive makes at times and most of us know what that sounds like.

I got it even when I wasn't on a call - a few seconds after powering up the phone and it was there
You guys are nerds
No, I can feel your pain! Hopefully you guys can sort this out and this is in general not a common problem with the N4.
i don't have this issue
It seems to be an issue with the electromagnetic shielding. I get this problem when I am next to my sound system and amplifier. Those things arent shielded. Now in school where theres basically nothing else here my earpiece is completely clean. Not even a hiss.
does it also emit a sound when it is swithced on, but the screen is off? i remember i had sth. like this (high-pitched sound) on my first google nexus s, but it was clearly coming from the screen rather than the earpiece.
Received a replacement today - it's A LOT better. There's still a very feint buzz, but it's barely noticeable.

Yes, even did it without a simcard inside. Definitely coming from the earpiece, if I moved my ear down the phone it was quieter/silent.
What about in airplane mode?

Didn't test the previous one in airplane mode, but just tried this one and it's the same.
Definitely getting the same issue with my N4; screen on or off. Can't imagine this being fixed by firmware, sounds like a bad hardware design.
I'm also once of these people who gets irritated by the sound of DVD Players/VCR/TV etc. But two other people I have shown seem to think its an issue too.
It's good to read a replacement was better, that's made my day.
The problem is certainly a electromagnetic shielding issue with the earpiece, I can stand in a middle of a field and it has that sound you often get from PC or Hi-Fi speakers when you stand close to them.
But with the earpiece you can't move it of course - so clearly a design flaw, and hopefully only on a batch?
That said, it does seem to be an intermittent fault, I've also noticed it doesn't happen within the first 10-30 seconds of a call. I wonder if the phone stops all background processes during the start of a call, but then later kicks in which causes those noises.

I can hear the high pitched noise from a CRT from, like, 100'. Can a lot of other people really not hear them? Also, deer/dog/insect deterrents that people use in their homes and yard give me an instant headache from the sound. Great. This does not bode well. Oh well, I'll cross that bridge if/when I get to it.

Exactly that, those who can't hear those audible repellents for pets, or not hear the Apps available which also emit very annoying high pitch sounds - then would not be bothered by the noise we mention here.
I'm certain if I took my N4 into a shop, the typical response from staff would be "we can't hear it"
I have this issue with my phone as well. Screen on or off. Charging or not. Noise is still present.

Loudspeaker Quality

As there is no similar topic specially for Loudspeaker I decided to create one.
I like the speakers of the phone sound good and bassy.
Although I had to replace the speakers (repair),
(cuz it got low by it self (hardware defect))
But I noticed the bottom speaker is thinner and more high frequency specialized in the other side the top speaker for low frequency (bass)
Idk if it is hardware fault or it is designed by Sony,
I want to know your thoughts abt the loudspeakers ?
I don't know about Z3, but in the Z2 the top speaker is more clear than the bottom one. I think it's probably some kind of technology. But in the other side, if you're watching a film in horizontal direction, you can hear that everything is happening on the left side and that's annoying.
if the phone gets wet especially the loudspeaker area the loudspeakers stop making sound and thd sound is emitted from some sort of loudspeakers internal to the phone which appears the be louder from the back of the phone.
i listen music in the shower, so thats how i found out. though it was interesting to share

That's kind of weird, my neighbor have the Z2 and he never had such problem, are you sure it's not hardware fault? If my neighbor find such problems he directly comes to me to ask me what's this etc, but I know he don't have this problem cuz u also use his phone to compare etc, so I guess for you its a hardware fault maybe?

Yeah I also listen to music when I shower and I can confirm that,
oh no dont get me wrong it's not a complaint, im suprised the phone knows when its wet enough to stop the loudspeaker, its a good thing =)

Hmm maybe the speakers feel pressure when it gets wet and it shows the volume down / stops the speakers ?
As an audiophile I will say that as a Mobile Loudspeaker it is quite good. Compared to anything else though it is still a low sound quality speaker.
But as a mobile speaker though, it is very good. It is loud, clear and doesn't "break up" that much. It got some bass, but not much.
I think it sounds better with the surround function on. :good:
Its pretty good, but not near the M8. Id say second best of any phone out. I don't get the left/right mismatch many of you have mentioned., I have been through 4 Z3s for cosmetic defects and all sound equal. Maybe its a quality control issue or I have bad ears.
When I go into the service menu and do a test of the speakers, I get the sound coming out of the top/left speaker on both. What's going on there? There is perhaps some sound coming out of the bottom/right but it's tiny in comparison.

Anyone else think earpiece is too quiet?

Maybe my nexus 6 was just that good but it feels like the v20's earpiece speaker isnt very clear or loud....I can live with lower quality but the sound level is kind of low (hard to hear people in noisy places)

Yeah its low (with my over the ear cans), went all in on a descent amp that can usb of my pc and/or directly off my phone. Like my cans to rattle sometimes. With my IEMs though it gets loud after 50-60. Id make sure you have enabled Hi-Fi sound on the phone first and found this app to be very useful in adding some punch and volume to my tracks. ----> Equalizer (by Smart Android Apps)

I'm experiencing the same. Extremely clear, no issues whatsoever.
Speaking of the Nexus 6. That phone was hands down the best Android phone ever made. If they re-released it with a fingerprint sensor, I would buy it again. Best speakers and sound of any phone. It could have used a better camera, but other than that, 9 out of 10.
As for the speaker sound in the V20. I think it could be a a bit louder. Clarity isn't an issue for me. But it's def not very loud.
On the T-Mobile variant this thing is loud and clear. If I turn it all the way up I can hold it away from my ear in front of me and still hear the other person clear enough to understand them. definitely no issues so far involving that

Yes loudness is the issue. Its too quiet if you are anywhere with noise like the grocery store.
Nexus 6 was a good phone but had issues (guess all phones do). The camera was pretty bad and buggy at times. Speakers were great but if you had lower battery they would automatically decrease the volume like 50% (even at max volume) that was insanely annoying. And lastly it throttled speed pretty badly when battery got low. Oh and it was pretty big, alittle smaller screen with the v20 but much smaller in the hand.

Pull up your phone app. Make sure it's on the dial menu and hit the 3 vertical dots in the upper right hand corner. Go to call settings. The last option should be one that reads "more" . Peruse that and see what may help. Good luck.

Only thing I can think of would be to try turning on hearing aid compatibility or maybe messing with the call clarity and noise suppression options and see if that affects anything for ya.
I have both voice clarity and noise suppression turned on and have no problems with low volume at all. I remember reading somewhere on a different phone e that the hearing aid option made it noticeably louder on that specific phone so you could try that and see if it works for this phone.

Am finding the same too, this time i have the voice clarity option enabled, lets see if it makes a difference. I find it soft in a quiet room, no idea how this will work out on the street. Might be forced to get a headset in that case.
Which would be a pity becaue this phone is all about audio. My speakers are perfectly fine. Why does the earpiece have to be so quiet
