Quiet buzzing in earphones while charging - Redmi Note 2 Q&A, Help & Troubleshooting

I noticed when I have my earphones plugged in while I'm charging my phone, I hear this quiet buzzing in earphones. Something like when you power on a speaker and then hold its jack with fingers. Haven't tested with different earphones, as I only have Piston 2, but my guess is it's a hardware problem.
Can someone else test it and report if they have the same issue?

I can't test it on the RN2 as I'm still waiting for Gearbest to send it. But your post reminded me that there was a similar issue with the phone earpiece in the Nexus 4.
There would be an almost imperceptible hissing/clicking when pressed to the ear. It does it constantly, with the screen/charger on or off . I'd forgotten all about it, as I never put it to my ear unless on a call (when it can't be heard). Just tested it a moment ago – still hissing, and has been for the last three years. I also hear some hissing with headphones, but it's much quieter.
I think the consensus was that it was due to imperfect shielding of the radio components.

[Q] Problems with audio jack

Hi all,
to my great frustration, I've discovered that my SGS2 line-out / headphones jack seems to have a slack joint, i.e. if you turn a connected plug around its long axis, a crackling sound is heared in the speakers and at some angular positions the stereo signal will be reduced to mono (i.e. one speaker gos silent). With one device (mobile outdoor speaker) I even had no sound at all at when inserting the plug with the wrong "orientation".
Did anybody experience the same problem or am I just out of luck here?
I am wondering whether sending back the device to the retailer (Amazon) or directly to Samsung (I'm situated in Germany) will yield the faster round-trip time, any experiences here?
Thanks!
PS: I know this may be a stupid question but can somebody PLEASE tell me how to search for multiple keywords with AND logic in this forum? Tried "+word +word" and "word AND word" (without the quotes) but nothing seems to work.
Are you using the headphones that came with it? My better half went through 4 sets of the stock samsung headphones with her original Galaxy S and all produced the same issue of losing one channel after a matter of days/weeks. having the jack inserted to about 2/3rds is a workaround but not ideal as you still lose some frequencies and it's insecure... They're just a bit pony.
No, I used different kind of headphones, including Sennheiser in-ear headphones and a standard male-male audio jack connected to some bigger hifi system. With some jacks I did not encounter the problem, but most of them lost some part of the signal with some orientations: I persume that the manufacturing tolerance of the jacks also plays a role...
Anyway, it's definitely not a problem of the jacks but of the device since I tried it with the SGS2 of a friend yesterday and it worked with the same jack that made problems with my device.
I will proceed sending my phone to Samsung for repair, I hope that won't take to long *sad looking*, I am so used to it now, it's card to survive to weeks without it.
I had the same problem, all I had to do was insert headphones cable "HARDER" into the audio jack until I herd a "click" sound.
I was way to over protective of this phone when i first had it, and wanted to handle too much with care, forced the dam cable in, and "click", sounded like it snapped into place, the audio worked correctly without cracking noise or without the need to wiggle to cable get clearer sound.
Perhaps your friends SGS2 is already used to headphone being inserted, but yours not. Just add a little pressure until you hear clip into place.
If this doesnt help, then repair or return.
Thanks for the hint, but unfortunately I had the jack inserted to the very end, so this was not the problem... sent in for repair now, let's see what happens.
I have a fix for you i think!!!!!!!!
ok . when i got my s2 like 4 days ago (at&t usa version) i noticed that when i plugged into my aux cable in my car that it was low sound cracking more volume on the left side , very annoying . NOW FOR A SIMPLE FIX FOR SOME TO TRY! PLUG IT IN ALL THE WAY! i noticed when plugging it in i wasnt fully plugging it in . it should go all the way down FULLY! the sound is perfect once this is done . I HOPE THIS HELPS YOU !!!!!! good luck

Ear buds

I'm having a problem hearing music using ear Buds / headphones and was wondering if anyone else was having this issue on titan. The sound goes real dull almost like non-stereo and I have to hold where the 3.5 mm jack is and wiggle the earbuds to get a clear sound. I bought new skoal candies and tried 3 other pairs so I'm guessing its my phone but was curious if anyone else was having this issue.
Thx
from Titan on XDA Windows Phone 7 App
ear buds and the like
It might just be your 3.5 mm connection...I tried mine out just now (I had not added music to my Titan previously) and plugged in and was very very pleasantly surprised at the sound quality. I had surmised for myself that my PDA was for phone and calendar etc, and the iPod or other MP3/4 player for audio - mostly for quality of sound. I won't make that mistake again. The Titan is good - very good.

DId you use IE while listening to Music? I don't have any problems with Music playback (Used it to listen to my music collection during work hours whole last week) However I noticed that when I launch IE (search, or by launching IE on its own) sound quality suddenly changes, and degrades..

Hm, I think it has something to do with bluetooth stereo vs headset profile. Weird that it happens with regular ear buds.

I think its defective, I'm going to call ATT tomorrow and have it replaced because I have to hold where the earbuds fit into the 3.5 connecter and put a little bit of pressure to get the sound to come thru. I'm glad to hear no one else is having an issue so thats good
I'm having issues too.
I had problems with my audio jack too. I was looking on here to see if anyone else had issues. At first, I thought that I had a failing headset but then I put another one in and after awhile it started doing the same thing. It's not right away but it seems to start up after a bit. It's really concerning me though. I'm considering getting a replacement and hope this is just a minor issue that affects a few units. I don't want to wait and have it develop into a bigger issue. It frustrates me though, because I had originally bought a focus s and the hands free button didn't work right. It seemed like an issue with the way it registered button presses. Now, I get this phone and the button works right but I'm having these audio issues. Argghh.
I don't have a problem with any earbuds , every one i tried works for me. It might just be your phone itself. maybe deffective? If i was you i would try regular ipod headphones or a friends to see if that really is the problem
hi all, question about the volume sensitivity on the titan. i used to have an iphone 3gs then switched to the skyrocket to try out android but i'm really unhappy with the android music players so i'm either going to trade it in for the iphone 4s or the htc titan (still within the 30 day period).
on my iphone i could set the max volume to wherever i wanted and would have plenty of intermediate volumes to get the level right where i want it.
however, with the skyrocket by the time i hit the 3rd volume level (0=mute, 1= up volume button pressed once) the volume physically hurts my ears and i like loud music.
i'm using the stock headphones that came with my iphone 3gs because i like the fit and the in-line remote. i know these have low resistance but still, only having 2 usable volume settings is ridiculously annoying because i can only listen to music really softly or a bit louder than where i want it to be.
how do you guys feel the volume sensitivity is on the titan? are there more than 2-3 acceptable volume levels for low-resistance (small earbud) headphones? thanks!
i use the included earbuds and the 30 level volume settings seem to fit most situations
Replace it since you're within the 30 days. I got a new one and the issue is cleared up, I had a defective unit. Very happy with it now

[Q] Headphone jack emitting crackling sound

The headphone jack on my Samsung Galaxy S3 I9300 (android 4.3) recently stopped playing music and playing a crackling sound instead. This crackling sound is in time with the music and if you turn it up kind of loud you can hear the music a little in the background. :crying:
When it stopped it was completely random- I was listening to music and when the next song started I couldn't hear anything, only the crackling when the volume was turned up loud enough.
It's not the headphones, because I have tried various different pairs which work perfectly fine on other devices. The speaker still works fine too.
I'm not sure of the reason... I did drop my phone into the toilet about 7 months ago and once more about 3 months ago, but this problem only appeared now. Can dropping your phone in water cause problems that long after the event?
Or it might be because I got my phone repaired yesterday? I had the microphone and the glass/touch buttons replaced, so I'm not sure if when that was replaced they knocked the headphone jack or something, but for about one day after getting that repaired the headphone jack worked fine.
Are there any things I could do to fix this problem? Or do I have to take it back to get fixed? And, if I do need it fixed at a repair shop, around how much will it cost? I've had a lot of problems with this phone and I'm just wondering if I should get a new one. My phone is out of warranty, and I'm not on a contract or plan anymore, so I can't just get a new one.
Take it back its probably hardware .
Or try factory reset.

[Q] Problem with noise cancelling headphones?

Hey there,
Today I decided to eventually officially get the xperia z2 so I opened the headphones and plugged them in. They're absolutely amazing, better than anything I've had so far in terms of in-ear headphones. However, I noticed a problem. Not sure if it's just me with faulty headphones but when they're plugged in and they're not like leaning a certain way, there's extreme noise, songs randomly change, Google Search app randomly opens etc. If I spin the headphones while they're plugged in as in just turn the 3.5mm jack around while it's in the hole, songs stop playing, there's really loud noise too. Have I got faulty headphones or a faulty headphone jack/phone?
Thanks in advance for any help! If some of you could please try reproduce this with your noise cancelling headphones and report back I'd appreciate it tremendously!
P.s it might be worth nothing I did put the phone in a bit of water for about 10 seconds just to test it is waterproof and I assume the headphone jack is too so it shouldn't be that right?
Jack might take upto few hours to dry up, says so in user manual

That's weird. I did the whole water thing yesterday afternoon so it's easily been over 24 hours and it has been heating up like crazy today because I've been using it so much so it should've dried up by now surely?
Thanks for your reply! :good:
Yeah it should be fine by now, then probably faulty jack or headphones as this is first time i hear this problem.

Just tried a standard pair of headphones they seem to work fine with no interference and no random music stoppages. If I spin the NC headphones while it is plugged in, I hear noise only in the right headphone. The noise specifically sounds like how it would if you were on the phone to someone and they were tapping their headphone mic on their end then the music stops. Hmm guess I'll be going back to get them swapped tomorrow!
Thanks again!
Edit: Just tried the headphones on my laptop and they seem to be working fine regardless of position. I think it may be the jack after all. Will be taking phone in to be swapped/repaired tomorrow.
Im no professor in these things, but i think nc headphones have more contact points compared to usual headphones, so if say 1 of those extra contacts were messed up, only z2 would react to it while laptop would ignore it and use them as conventional headphones. Just my theory, dont know how valid it is

Yeah I feel like either one of the points are messed up on the headphones or one of the contact points in the jack is messed up. I'll have to go in store tomorrow and try another pair of 5 contact point headphones as I don't have any others with me. I'll update tomorrow afternoon thanks again for trying to help! :good::highfive:
I have exactly the same problem, 10 - 15 minutes after a brief bit of radio in the bathroom, but the phone wasn't inside the actual shower, I plugged my noise cancelling headphones in and immediately heard a couple of small pops. Thought nothing of it to be honest, but as my journey to work went on the noises got louder and more distorted and seemed to be being caused by the background noise itself. Then the phone just went mental, started getting very hot and taking me to the Smart Connect App for no reason, the speakers stopped working completely, could call people, but not hear anything (dial tone or voice), even after multiple re-starts nothing. Tried calling my phone from my desk phone and the speakers were working for ringtone/notification, but not music and voice! Then after turning it off and leaving it for a while, things seemed to come back to normal, but then I tried plugging the headphones in and once again the phone went mental. Running stock ROM, unrooted on 17.1.A.2.55 (STILL!) I'm a bit miffed to say the least. The phone has in some respects exceeded my expectations, but sometimes feels like a half-baked product.
Now the phone isn't recognising the noise cancelling headphones at all and the phone has mad battery drain and random volume issues (alarms are refusing to silence and quiet, then loud speaker volume) considering I was in a steamy room and not actually immersing the device in water.. This totally sucks going to Sony store tomorrow..
OK just an update on what's been happening with my phone/headphones since my last post. Went to Sony store (and three store) and was basically told "meh, phone Sony" so I called 08705237237 and the girl on the phone told me to "repair the software" first and if this don't fix the problem then send headphones in for repair! As for the headphones, they are no longer recognised as noise cancelling ones for 99% of the time, when they are recognised, they make the phone go utterly mental and freeze up! Very annoying. Will try software repair and report back. Will this error affect the use of the stm10 mic I have on preorder, will have to see..

Hissing/ 'SSSS' sound from Redmi Note 3 Speaker and When Connected to Amplifiers

Hey Guys.
I'm creating this thread since I did not find any other old thread about this issue.
When a song or any audio output is done through the Redmi Note 3's Speaker or when it is connected to a Amplifier like a car stereo then there's an Awkward ssssss or Hissing sound.
I've used Two Different models of the Redmi Note 3 thanks to Amazon and both of them have this.
It has a very very low possibility of hardware error.
When a song is played at 1/7 of the total volume, put your ear near the device speaker and listen carefully. You might notice a weird hissing sound. It goes away when there is deep and strong bass but is there lots of times.
Using an amplifier it is most noticeable at lower volumes.
I hope you people understand.
Respond ASAP!

I too faced that situation... But in my case..
The 3.5 mm jack is broken..
I mean.. There's no problem with the phone.. But in sound system I use...
Have you checked this problem with other speakers ...??

Hey,
I actually have noticed this when I played music in my Car and also from the phone's Speaker itself!
Both when the volume is Very Low....
I know it's not a problem with my piece because I've checked with many RN3 Users and same issue is being detected there too.
My RN3 is new and in superb Condition and so are the other Appliances like the Car Stereo I used.
Even then this Hiss sound is there.
I wonder of its a problem with the Chipset altogether since there isn't a sound/music chip in it...
I hope it's a software issue and gets resolved fast...
When recording sound from the speaker output yes the sound is levied towards the high end, this is probably what causes the hissing sound in your amplifier since it can't properly amplify that freq or something along those lines, I'm not too sure since I'm no sound engineer but that's just my 50 cent.
Edit
Dumb me, your amplifier is probably a 3.5mm headphone Jack right? If so then there shouldn't be this issue and my above statement wouldn't apply ;-;
I noticed this when using Viper Audio. There was a small but noticeable hissing in the left earphone. It went away when I turned off playback gain control.
Maybe check if any equalisers or headphone effects are on and turn them off?

I had checked everything possible. I even did now.
No part of the settings, equalizer, audio effects could fix it....
And where's the option you're talking about for playback gain control? I'm still unrooted with a locked bootloader on MIUI V7.2.3.0LHOMIDA
The sound is there in both speakers in my case. I'm not using anything other than the stock music application and some great songs on an amplifier I.e. Cars stereo
Anybody has got the solution? I am also facing same issue ??

Not till now.
I've bought this Bluetooth audio adaptor that serves my purpose in the car.
Funnily nobody at Mi noticed this.
I'll do a bug report highlighting this issue.
Everyone else plase do too!

I have also dropped them a mail. Will also report bug. Thank you for your solution but I'll probably have to wait as my car system does not support Bluetooth.

Even mine didn't support Bluetooth.
If your Stereo supports USB and Aux in, you can also go for the adapter since it only needs those two.
USB for Power and Aux In for the Music.

I had a similar problem. Whenever I connected my headphones to my Redmi Note 3, there would be a weird hissing noise at low volumes especially. At higher volumes, it would reduce. I found a fix to this on Reddit, but you need to be rooted.
https://m.reddit.com/r/Xiaomi/comme..._3_pro/?utm_source=mweb_redirect&compact=true
Looks like a legacy. We are well into 2017 and the issue still exists. I bought my RN3 a couple of weeks ago and noticed the hissing on the third day of use. I just have been ignoring it. After all, it's a Chinese phone. I bought it and I have to live with it.
Good afternoon! The solution for problems with Redmi Note 3 and AUX is the following (solves the problem of correct detection and noise during playback): it is necessary to solder or otherwise connect resistors with a rating of 10 ohms between the common "0" wire and the left and right channel wires (I did 17 Ohm , did 10 ohms - both options work).
After you make this cable, the sequence of actions is as follows: the cable is first inserted into the smartphone, wait for the icon to appear with the headphones, and then insert into the AUX-input of the radio or audio system.
