Broken OIS, you might want to bring it back to ZTE
Few people actually reported that it fixed itself, but it is a known issue of this phone, and I think it is much more prominent on the A2017U

Micro sound when startup on LG G2 D802!

I just bought my LG G2 for two weeks. It s a really amazing android phone and I love it. But yesterday when I started it up in the early morning and noticed the micro sound from G2. This sound like the sound from a hard disk when it run, u must listen carefully to realize it. Then I pay attention at it and actually hear this sound from my G2 when run some heavy apps or games.
Is my G2 OK? Have anyone else heard this sound?
I've never heard a sound. Sounds like a short with the speaker or microphone. There are no moving parts outside of the camera. How loud is it?
I noticed my. NEXUS 7 2013 makes a sound when I mute the audio while playing a video. Its a slight frequency pitch but stops even with volume set to 1. It starts and stops at random.

Not sure what you describe is the same.
I have static noise - buzzing in the earpiece. Even when screen off....annoying in calls...
In my case it's an old known bug of LG devices(someone said all devices to have this to some extent, however LG's is the only one I can hear it from). I reported it few times... It's very well documented in the Nexus 4...
At LG G2 the users do not like to be told that their precious is bugged...
Some do not hear it or do not want to hear it.
The buzzing, static etc. You can hear it even when the screen is off...
Supposed to be shielding issue?
Maybe yours could be the same
Can you check with screen of if you can hear some buzzing?

No, not sounds are made from speaker or microphone. It seem be made from one of hardwares of G2. I don't know exactly. This sound like sound is made from hard disk of PC when it runs.
Similar here...
I have this sound on headphones in the right channel.
It's very low and as quachhanthanh says it's like a hard drive starting up but much lower with similarities how radio frequencies disturb speakers.
It increases a little when I touch the screen but is constant like a very low beat when not using the screen.
I will try this later on CM latest stable.

Background noise when recording video in silence

Hello boys,
Is all this background noise normal when recording video in complete silence???
https://youtu.be/T3qTX0aTv3o
I didn't notice until today, but I had not tried it before either. Normal recording with voice or music in the background is perfectly ok.
Thank you.

Yeah, well, maybe it fixes it, but if it is my phone that is faulty, I'd rather prefer to have that fixed.

I didn't have a nexus 4, but nexus 5 had this sort of problem too. But I can't remember it as bad as the video I posted. If it's software stuff or design flaw it can't be helped.. but I'd like to make sure that it's not just my device, otherwise I will better RMA it.

The intermittent buzzing(I think it actually sounds like a cat purring) is the auto-focus on the camera. It appears that every Nexus 6p has this issue in some capacity.
Here is a video I recorded demonstrating what I'm talking about.
When I noticed the issue an hour or so ago I started researching it myself and saw some videos others have recorded and posted of the problem and honestly it doesn't seem like it is as bad as it seems. The noise itself is very hard to hear if there is any background noise. I recorded my video in silence, so the "purring" is very audible, however in your video and others I could barely hear it, and that was while also listening for it.
In fact in my video I can't hear that clicking noise. I will try sometime doing the same test you did.
The reason of the thread was the general noise that you can hear at the background all the time. I ordered a replacement but it had the same noise, so I assume it's completely normal and I returned it since the screen of my first phone was, I think, better.

Sound quality speaker Mate 8

Hey guys, I'm new here and enjoying my silver Mate 8 to the fullest but I have a question for you all. The sound of my Mate 's speaker sounds solid when the volume is half way but when I crank it up the sound is getting distorted and not as clear as volume low or half way. Is this normal for this phone or could I have a bad unit? Also, when a sound (music, Youtube etc.) is finished playing i hear a soft static for 1 or 2 seconds followed by a click. The click is only noticable when I'm in a quiet room or if put the speaker to my ear. Is my OCD getting the better of m:silly:e or is this really an issue for a phone swap?
Thanks in advance!
I guess it is normal. Comparing to s6 edge. The speaker of mate 8 produce better sound quality In medium volume (give mean impression of wow, never hear the vocal and music instrument mix so well. Where s6 edge vocal is clear but instrument sounded too tight together.)
. But if compare both on max volume. Mate 8 indeed suffer some distortion and not clear.

Oke thanks. And the clicking sound after each sound is normal or might be a hardware/software issue (see a lot of 'complaints' about this issue on all brands)? I just played a Facebook video and noticed a much softer click than with the system sounds/music. You should expect the sound to be the same all around if it is the speaker going off. Weird.

i love my mate 8 its really a good device but i have only one issue with it, its the low speaker volume i noticed this since the first day i got it (speaking from an ex. samsung note 5 user) i can surely say that the note 5 speaker is much louder and its so strange how big the difference is so i was thinking that maybe i have a defective mate 8?

[Video] Any way to stop mic clipping in loud environments? - Such as a live band?

I play in a band....When I record us playing live, or other bands, it doesn't distort, but there is a horrible clipping noise that sounds like a "quack" or "quirk" noise when the audio threshold is breached. It was like this on MM and I was hoping Nougat would be better, but there is no change.
On my last 5 phones, this NEVER happened (Nexus 6p, Moto X Pure, Galaxy S7 Edge, S6, and HTC One M9). Actually, I haven't really had this problem since 2013. My other band members iPhones are perfectly clear as well.... But my recordings are virtually useless due to this horrible noise every few seconds. Regular, everyday stuff is fine - it's just loud band settings.
Anyone know of anything that might help? I'm on the stock ROM, but rooted if I need to change anything?
Here is an example - a 25 second clip of my band on YouTube:
It sounds like the mic is being over driven and clipping/distorting. How close is the phone to the bass?

The bass is completely on the opposite side of the stage, about 25 feet away in this video. We didn't use subs at this gig, and my phone was about 5 feet behind the main speakers sitting on a towel on a concrete floor.
To me, it doesn't appear to be the bass.. It's when the drummer is hitting the snare, which is opposite of when the bass is usually hitting. The snare is usually the loudest thing on the stage.
I've tried recording at every show since I've had my phone around August or September (23 - 25 shows)....I've had it at all different points behind the speakers, in front of the speakers, on the bass side, behind everything, in peoples hands..... ect... It just doesn't like loud music.
I was wondering if there was a way to up the sensitivity of the mic, or DB where it is rated?
I've been recording my band/s for the past 7 or 8 years (ever since the iPhone 4s days). Had some that distorted bad, but usually I could tell it was the bass. But ever since I had my first HTC M7, about 2013, I haven't had any issues until now with the A7.
Did you find any solution? I go to live shows a lot, and sometimes I like to record one or two songs, I used to have Motorola g4 plus and the audio was OK, but I just bought the g5 plus and the audio is totally garbage! :crying:

No, but I haven't tried for a few weeks - since updating to 7.1.1, but it was this way on 7.0, so I don't foresee it any better.
My friends with iPhones (6-7) and Galaxy S6/S7's all sound fine.... Mine doesn't when recording something at high volume.

I almost thought about trading for a LG v20 (I found on Craigslist) or upgrading to the S8 when it's out, but I really like this phone. I'm going to try a different camera or something?

I can say I don't have this problem, I have been into some loud environments and even recorded a Big Band and the sound was fine; probably I will go tonight to a club or something and can test as well, but as for the tests I have done before regarding this topic, I haven't found any issue. My device is A2017G.

Hmmmm, this is the 2nd Axon 7 I've had - and both had the same issue. Maybe it's just louder behind the speakers?
I may try setting it out in front, 10 or 20 feet back and see how that turns out? It still irritates me a little, because my other phones didn't do this when I'd record the same way and place. Even going back 4 or 5 years ago to my HTC M7.

Just as I promised, I recorded a video yesterday night in a loud environment; I was no more than 1-2 from one of the speakers, and I think the quality is pretty decent:
https://goo.gl/photos/XXkdG1Z1M4ja1mAd8
P.D.: The video seems a little blurry, but I didn't even focus anything, I just grabbed the phone out and start to record to test the audio and I didn't care about image quality.
I've recorded live bands and the sound has been fine, far better than on any previous phone, but I haven't tried with version 7.

Is that using the stock camera/video?
I tried a couple different cameras from the playstore, one was no different than stock, one was horribly worse.

Same
Well, I recorded more video of my band this weekend. I believe the issue comes form the side of the stage I'm on required the microphone to point "towards" the stage, instead of away.....So it's extra sensitive. I recorded half a song with it one way, flipped it over and finished out the song. The half with the mic pointed away only clipped one time. The half with it pointed towards us, clipped about ever time my drummer hit the snare.
Still not as clear as my drummers wife and her S7, but livable now.
I also read you can put scotch tape over the mic and it'll help too?
[UPDATE]
Mid- last week, I made the switch from stock, to LOs.... Just tested the recording, and the problems I was experiencing in stock, with clipping, don't exist in LOs... Not sure why, but they're all gone!
I recorded several songs tonight, at a louder volume, with no clipping at all.
Just throwing this out there.

Poor sound quality

Just got my 6gb Variant today in grey colour, the screen is a bit too warm for my taste and turning it cooler makes it look ugly, also I think brightness is not as good as note 5 pro. it has purer whites and gets way too brighter than this phone. But I guess I can live with it given stock android is way better than ****ty miui. What is bothering me is poor audio quality in headphones and over Bluetooth too. I'm coming from iPhone and redmi note 3 and comparatively, they both get very loud than this also sound quality is superior to this phone.. I can live with other shortcomings like the poor camera (hopefully gcam will fix most of the issues there) and warmer screen but the sound quality is very important. Is there a way to fix this? or I'll have to learn to live with it :\
Root and instal v4a.
PS: For me sound quality is good even though its not loud but enough for my tastes.

I was so busy unlocking bootloader and rooting I forgot to check the main function of it lol just tried calling and it works perfectly on my phone. I would not install any roms on this phone, buying a phone with stock android was to avoid flashing roms, as almost all roms have some issues. I'm just going to use stock firmware with root, adblocker and gcam and that's about it. I want stability more than the features. try going back to stock android with a locked bootloader and all. if that still doesn't fix it, get a replacement from Flipkart maybe there is a hardware issue with your device. The only sound issue I've is, it is not as loud as iPhone or my Redmi Note 3 but rest seems to be in order. Hope this helps. Cheers.

I faced the same issue, the audio volume and quality was low on bluetooth (Headset/Car Audio). Flashed Firehound and that problem is resolved, though the sound is still a bit bright for my taste.

I am using RR ROM since I got this device.
Didn't check call quality for bluetooth issue in stock ROM.
I did my research and found out that call quality may get better after 3 or 4 days in stock.
Don't know about custom ROMs though.
I am going back to stock after couple of hours.
Let me check and confirm the bug.
