Weird clicking noise from speaker.

Does anyone notice a very light clicking noise from back speaker when on speaker phone right after hanging up on a call?
Just the NSA, disregard.
Lol,thought it might have something to do with radio/network stuff or like u said nsa..smh
I notice it makes the clicking noise anytime the back speaker gets used at all,there's a light hiss then click,guess kinda like an amp would sound when being turned off.
No one else here it?

Yes, I hear it. This has been audible on every phone i've had in recent memory, you probably just never listened for it before. Anytime sound is routed through the speaker you get the hissing, followed by the click as the amp shuts off 2 or 3 seconds later. Sometimes it's audible through headphones also, depending on the headphones.
Lol yeah only noticed, because when on call using speakerphone it clicks 2 or 3 times and it's just a tad louder then when turning off any other time,other wise probably would never heard it.
I have a N910F and noticed it this morning. I here it, it's like a frying noise, and if you get close enough you here it every time a sound is routed throughout the speaker on or off.
I'm on Lollipop 5.0.1 Baseband version N910FXXU1BOC3.
I don't think it's normal, Samsung is playing around with the audio system, you couldn't turn off sound completely until this ver of lollipop and still even when audio is completely off you can here the speaker fry when something is routed to it.

Speaker crackle - defect, normal, common?

I've had my phone replaced 4 times now, each had a problem. I'm on my 5th Nexus 6 and this one has speaker crackle in the top speaker. I noticed it when I had a Facebook notification, but I haven't heard it since, so obviously. I can only hear it when I play some sort of sound, and afterwards, once the particular sound has finished playing, I hold it right against my ear, and it's sort of like white noise with like crackles and pops in. I can't hear it when it's away from my ear and it doesn't seem to affect call quality.
I've noticed the bottom speaker outputs normal white noise once audio has finished playing, but again, only when holding it up to my ear.
I've read a lot of people have had this, but their replacements seem to do the same thing. Is this worth a replacement (in my case a refund, I don't want a sixth phone) or is it just one of those things that won't really affect the phone?
Move doesn't appear to get any worse when the battery is lower either. It's constant when Google Music is open, when a song is on pause, but I only know this because I held it right against my ear.
Surely, if it was a defective speaker, the speaker wouldn't sound as good as it does playing audio?
Anybody else's so this?

Hello,
I have the same problem. It's a low frequency noise... after each sound, but only if you hold it to your ear.
Let me tell you that, that does not affects the overall product. I have deal with lots of FACTORY BUGS (like Sensation 4G BT antenna) and so on, but this 1 sec low frequency does not affect as much.
For me is only more noticeable when on low battery.
Hope this helps!:good:
I think it's more of a software issue, are you completely stock? I flash a lot of Roms. There are some I get the crackle noise some that I don't. I also use lean kernel which has updated audio and display drivers... No crackle or pops for me in quite a long time
Is it definitely a software problem? I read online about people saying its hardware, but if it is software I'll keep it. If not I'll have to send it back Monday... would a factory reset do anything?
And yes, completely stock.
And same, mine is worse when on low battery. If I play a game with sound off, there's this constant buzz coming from the top speaker.

Bottom Speaker Louder then Top?

As the subject states.
I'm noticing my bottom speaker is massively louder then the top speaker when playing music and when in call on loudspeaker.
I test by simply covering one of the speakers. The effext is very evident.
The top speaker is very low compared to bottom.
Is anyone else noticing this or has my top speaker failed on me?

I'm noticing the same thing. Balance seems to be off.
If you have had it like that since the beginning you are most likely experiencing the same problem i had.
When the phone was built in the factory, a small plastic piece above the speaker wasn't removed correctly so it muffled the speaker. It went under the warranty cause it's a a problem from the factory

Starting to think this is normal?!
Which is weird.
I say normal. Because I just ran the rest on my girlfriends z3c and she notices the same low sound from top speaker.
Lame.
Gonna go test this is store on the demo models see if this is indeed normal...
Tried the demo model in store today I can confirm that both top and bottom speakers provided an EQUAL level of sound (when playing music at least.)
Unlike my phone which has clearly suffered over time through no direct fault of my own.
Sending it back tomorrow

External Speaker Distortion?

Is anyone else experiencing distortion with their external speaker? My ringtones begin to distort around 1/4 volume and very noticeable 1/2 and up. Does the same for notifications. Not as noticeable during videos and music but still present.
Just trying to figure out if mine is partying for the course or a dud. Thanks in advance for any input.

If you hold your finger or hand very close to speaker, mine has distortion too.
Hand placement doesn't really seem to affect it...
no distortion at all on mine.
I noticed when playing louder videos or when im on speakerphone and the person is talking there is a bit distortion in the sound sort of a tiny bit of fuzz and i noticed this also on my egde plus and a bunch of store models as well can anybody confirm? I mean its not bad but still my phones are $700-$800.
Im Tmobile
My speakers sounds (imo) awful, it's distorted and warbly (sp?). For a phone with such good headphone audio I don't understand why the speaker (or in the surround sound mod) both speakers sound so bad. They both have that issue for external audio, haven't tested call audio yet because I never really take calls and the one I did I forgot to notice.
No issues here. Probably dirt getting in with the speaker, the grill holes are pretty sizable.

Not minutes after I opened the box. I THINK I may have a lead as to why it's bad. If you listen closely and FEEL the phone. It appears to me that the low notes are resonating with the glass back panel (or something/everything else, whatever it is) and causing vibrations that both warble and distort the sound and speaker(s). I could certainly be wrong, but that's what I'm hearing. As for a fix, I haven't a clue, if I'm wrong and it's software, I haven't a clue. I don't have near enough time to do non-guided digging into this. Only what little listening I do with speakers. (Considering I'd rather use what comes out of my CXN).
Distortion
I too have distortion on my external speakers. Exactly the same symptoms..
I will be very interested in hearing about a fix.
Cheers

Low microphone volume
