[Samsung Galaxy Note 20 Ultra Questions & Answers] rotalution:
Hi can you please try SIM 1 and micro SD card and see if you get 5g?
[Samsung Galaxy Note 20 Ultra Questions & Answers] evenshop:
Hello, yes 5G works with a SD card
[Samsung Galaxy Note 20 Ultra Questions & Answers] rotalution:
Thanks
[Samsung Galaxy Note 20 Ultra Questions & Answers] evenshop:
I flashed TGY CSC of July FW with odin (it worked), but now I only have 5G on the second slot, on condition that sim 1 is turned off.... Maybe if I we can find the winning combination (CSC + FW) we can have 5G work with 2 active sim cards (I mean one card 4G and the other 5G, I know it's not possible to have 2x 5g....)

[Xiaomi Poco X3 NFC Guides, News, & Discussion] black_dott:
I was really hoping to get at least normal headphones output from poco x3, its a poco device, no? I've used poco f1 for 2 years now, sound output from 3.5mm jack was nice and loud (at least), im using it with blon-03 and sound is, man, i cant listen to it more than a few minutes (ear fatigue is horrible). Can't believe that anyone didn't noticed this BIG issue.. cmon i havent heard such a bad sound EVER. Tried to use xiaomi's headphone presets, equalizer, sound calibration.. not even close .. after a few days (after update) tried it once more, aaand flashback, sound is simply said non usable. NO BASS, MIDS PAINFULLY SHARP, EAR PIERCING HIGHS.

im deeply disappointed, if this ENORMOUS issue is due low quality 3.5mm jack... not just software (writing this with fisical PAIN in my ears)
[Xiaomi Poco X3 NFC Guides, News, & Discussion] berni502:
Nah its not that bad need some Viper to boost it and schould be fine ofc depends on what headphones you use maybe u need some external amp and dac idk
[Xiaomi Poco X3 NFC Guides, News, & Discussion] black_dott:
as i said.. on poco f1 i didn't expected hi quality dac, and i was satisfied with sound quality and loudness, i use blon 03 earbuds (iem) and there's no bass.. and overall quality is not good... ill try some apps, maybe it will help
[Xiaomi Poco X3 NFC Guides, News, & Discussion] PsychoAssasin:
Might be a dumb suggestion, but make sure you're actually plugging in the jack all the way in. I've heard complaints before on other phones, and the reason was because the last 0.5mm was not pushed in. Often times cases can block the full engagement of the jack depending on the design.
[Xiaomi Poco X3 NFC Guides, News, & Discussion] black_dott:
tried it immediately when i heard the deference between poco f1 and this one (poco x3)..tried to install some app (beats).. nothing.Dont get me wrong, I'm not picky, just sound quality isnt there..quality is LOW, tried another pair (also iem quality) of earbuds and they sound BAD.
[Xiaomi Poco X3 NFC Guides, News, & Discussion] berni502:
try other headphones on my KZ ZS10 its not the best but decent do the sound volume setup and try mi headphones preset works for me :P plus eq on your taste

Didn't Xiaomi specify that the POCO X3 was HI-Res Audio certified?

I'm having doubts as to whether I should buy this phone. I want that sweet 24-bit/192kHz audio!
[Xiaomi Poco X3 NFC Guides, News, & Discussion] PsychoAssasin:
I'm still waiting for my phone to arrive, but this would be one of the first things I check. That said, there is a small possibility that your jack may be defective, or something else going on in the background. I've had my fair share of cheap crappy mp3 players in the past and the worst sounding DAC I've ever experienced was still passable to 99% of the general public.

This review of the Poco X3 tested the frequency response from the DAC and it looks perfectly fine.

https://www.laurentwillen.be/en/test-reviews/poco-x3-test-review-camera-photo/
[Xiaomi Poco X3 NFC Guides, News, & Discussion] black_dott:
it doesn't sound as defective, just bad.. in a comparison to poco f1's...
[Xiaomi Poco X3 NFC Guides, News, & Discussion] grd549:
Can anyone try to measure with RMAA with proper sound card?
[Xiaomi Poco X3 NFC Guides, News, & Discussion] PsychoAssasin:
I dont know what this person tested with, but these are the usual graphs/information people are looking for.

https://www.laurentwillen.be/en/test-reviews/poco-x3-test-review-camera-photo/#local-15

What you described in the opening post certainly sounds as defective. The typical deviation in phone DAC quality is usually very subtle and only noticed by a very small subset of people with high end headphones. There is definitely something wrong if you are getting "NO BASS" and ear piercing highs.

Is anyone else experiencing the same?
[Xiaomi Poco X3 NFC Guides, News, & Discussion] CaPicote:
That sounds like a defective unit, either that or you're VERY picky.
[Xiaomi Poco X3 NFC Guides, News, & Discussion] Zasnizas:
I don't know with other people but for me the sound quality is good with punchy bass, mid is quite good I can hear it clearly and high is good and details. Overall I'm really satisfied with the sound quality :good:
[Xiaomi Poco X3 NFC Guides, News, & Discussion] Rezio:
Can someone confirm the audio output quality via the jack by comparing with other devices.

Would really help me to make my buying decision ;/
[Xiaomi Poco X3 NFC Guides, News, & Discussion] black_dott:
one thing happend... i was reading your reply, and i had to try it again, blow the 3.5mm just to idk, do something... played music again, and i was like WHAT,? theres bass... i can't believe it.. sound for some reason got better.. i cant understand it. Day Before i also checked that the plug was properly inserted and it was,.. doesn't matter, its working ok now.
[Xiaomi Poco X3 NFC Guides, News, & Discussion] berni502:
The phone was straight from the production line jack as a part was bring to it form another supplier, yes there can be some **** in it sometimes ;P nobody is perfect :fingers-crossed: glad its working better

Thanks man , will definitely consider buying it now :highfive:
[Xiaomi Poco X3 NFC Guides, News, & Discussion] hachuwaka:
I haven't noticed the 3.5 mm jack being bad, tbh.
[Xiaomi Poco X3 NFC Guides, News, & Discussion] bacitoto:
Just like to add that I can't get my headphones very loud and they're only 52 ohms. edit: Ok the volume is really low which isn't a problem with my redmi note4 (LOS), I'll try editing .prop file in a few weeks and see if I can raise a lil bit.

They sound fine, the jack should be 24-bit/192kHz which is fine for almost everybody
[Xiaomi Poco X3 NFC Guides, News, & Discussion] Rezio:
I believe the output quality might be inferior than that of MI A1 ?
[Xiaomi Poco X3 NFC Guides, News, & Discussion] Spartoz:
The 3.5mm jack is trash on the X3

You can see a test here with real numbers: https://www.lesnumeriques.com/telephone-portable/poco-x3-nfc-p59695/test.html

So it's not just your unit, it's all of them :(
[Xiaomi Poco X3 NFC Guides, News, & Discussion] berni502:
nope mine is fine ;P not the best but ok ;P
[Xiaomi Poco X3 NFC Guides, News, & Discussion] PsychoAssasin:
Yeah sometimes things can get stuck in the jack. Glad its working fine now though :good:
[Xiaomi Poco X3 NFC Guides, News, & Discussion] Stewge:
Got my X3 and tested this myself. The sound by default is definitely not right but I suspect it's due to processing. From my testing, it's applying some form of Compression and treble boosting.

There's some settings in "Settings -> Sound & vibration -> Sound Effects". There doesn't seem to a way to disable the processing entirely. The default is preset is "Smart".

I've set it to "Music" which seems to have the least processing but still has some weird treble boosting. Movie has lots of compression and Voice also has some crazy mid-high boosting going on and cut low/sub-bass. I'm guessing the default "Smart" mode.

I'm testing on ATH-M50x headphones (relatively low impedance) so can't comment on high impedance headphones. Other devices are my desktop UMC204HD DAC, old LG V20 phone (very good onboard DAC).

EDIT: Just adding, using Foobar2000 + OpenSL mode (which bypasses any ROM sound processing) makes the sound VERY muddy. A lot of the high end is lost. Doing the same on my V20 does not have the same effect. I'll have to see if a USB DAC has the same issues (don't have one) as that would immediately tell me if it's the software end or hardware.
[Xiaomi Poco X3 NFC Guides, News, & Discussion] berni502:
how do you use this usb dac any custom rom or mode?couse usb auduo seems not to be supported in xiaomi with heapdhone jack and poco too.
[Xiaomi Poco X3 NFC Guides, News, & Discussion] bacitoto:
Mine is disabled (greyed out) and I can't seem to enable it. Is there any app or other setting I need to enable before?

I suspect debloating the phone removed one app that affects this, just need to find which one
[Xiaomi Poco X3 NFC Guides, News, & Discussion] Stewge:
USB audio does work so long as it's a full USB DAC. Can confirm my Steelseries Arctis 1 dongle works. Some of the cheaper dongles just re-route analog audio output which presumably doesn't exist on the Poco X3 Type-C port.

I haven't fully debloated my phone, I only removed some of the more "obvious" bloatware.

Otherwise I've got some further findings as I remembered my Steelseries Wireless headphones actually use a Type-C adapter, which allows me to test some theories. For reference I'm testing with the track "Below" by Leprous. Great prog rock/metal band if you're into that. There's lots of stereo separation, some sub-bass and the cymbals in the main chorus are very forward in the mix. The audio through the headphone jack is boosted exactly where those cymbals sit, making it sound quite bad, which led me to post here.

1) OpenSL mode is still muddy on the Type-C DAC. I suspect this issue is software then, as the DAC should bypass all audio hardware.

2) Audio in the Type-C DAC is STILL affected by the "Sound Effects" Preset. However it only seems to be a compression effect here, not EQ. The Music preset seems pretty flat and normal to my ears.

3) Type-C + "Music" preset seems to be the the best I can get it right now.

I'll be interested to see if future custom roms (particularly ones based on AOSP) fix the issue with the headphone jack. Even the cheapest of the cheap headphone amplifiers and DACs are not "that" bad these days so I'd be highly surprised if the hardware is actually at fault for the headphone jack sounding bad.

Sound out from 3.5mm very bad quality, use with my moondrop blessing2 and dunu dk3001 sound very harsh.
[Xiaomi Poco X3 NFC Guides, News, & Discussion] DP FH:
Same problem for me, very different compared to my PC and my previous Redmi 8. Sounds like you're on a phone call the whole time.
[Xiaomi Poco X3 NFC Guides, News, & Discussion] SeekerofLight.iz:
I'm not exactly an audiophile, but I haven't experienced any problems with the 3.5mm jack worth noting. Seems totally fine to me. I compared it to my old Samsung I had lying around, as well as an Alienware laptop, and it sounded about the same. Regardless, I've installed Viper4Android and it's improved my listening experience exponentially, as it does with every device I install it on lol.

Whether or not you have any complaints about the 3.5mm jack, I highly recommend installing Viper, given that you've rooted your phone (which tbf, does come with its own share of drawbacks like Google Pay / SafetyNet). Either way, I consider it to be the holy grail of audio processing for Android. I do wish there was an option to disable all MIUI audio processing in the "Sound & vibration >> Sound Effects" menu as it does seem to affect Viper's processing too, but I've decided to keep it on 'Music' as a few people here are saying that seems to be the most flat.

I have an issue when the headphone is plugged and i try to call someone there is two things posible :

The phone activate automatically the mute button !

The phone activate the stereo speakers instead of passing the sound through the headphones !

Do you guys have the same issues ?

How to install V4A? Magisk?
[Xiaomi Poco X3 NFC Guides, News, & Discussion] SeekerofLight.iz:
Yeah, Magisk has a module for it, but if I recall correctly, it actually didn't immediately work for me when I tried it. It only worked after I installed the app from here, too.

I recommend installing the Magisk module and the app from that link, as that's what ended up working for me.
[Xiaomi Poco X3 NFC Guides, News, & Discussion] berni502:
changing region for example on usa will boost volume on jack
[Xiaomi Poco X3 NFC Guides, News, & Discussion] Alvian_P:
- UBL your phone, install TWRP, then root with magisk

- from magisk module install Viper then reboot

- after reboot, open Viper then will prompt install driver for viper, usually need reboot again

I have this problem to with bad sound than my old poco f1, now waiting time for UBL new X3

3.5mm jack here is a good one, almost like my ZTE Axon 7, which tells a lot.

[Xiaomi Poco X3 NFC Guides, News, & Discussion] SkaboXD:
Notebookcheck.net says that headphone jack is good on Poco X3 and they showed it with test pictures.

I quote: "The 3.5-mm audio port of the Poco X3 leaves a very good impression. The sound output is very linear and at 91.16 dBFS"

Here's review: https://www.notebookcheck.net/Poco-...pment-champion-in-the-mid-range.498021.0.html

I can say that 3.5mm quality is good, but not better than ZTE Axon 7, which I expected. But Poco X3 drives my M50x's much louder that Axon 7 though you can notice distortion at max volume. Overall, I'm happy with audio performance of this phone, it even has better speakers with more bass which is amazing.
[Xiaomi Poco X3 NFC Guides, News, & Discussion] @Shekhar:
Well it's Hi-Res certified

Well it's official that it's both speakers are Hi-Res certified. And the signal is traveling through the DAC, so it means it has atleast 24bit/192KHz quality.

You can go and check on the official poco website.
[Xiaomi Poco X3 NFC Guides, News, & Discussion] ztemx:
I resolved this issue by using an adapter for iphones

I solved this same issue by using an adapter. Seems that this phone requires old earphones for iPhone. To use Android/Nokia earphones, it's required an adapter. There's a little difference in the order in the poles of the plug for both types of phones.

You can get the adapter in the famous chinese store. Seach for "CTIA to OMTP".

Greetings.
[Xiaomi Poco X3 NFC Guides, News, & Discussion] Gooler:
I've tested mine after seeing this thread. In my unit either the jack is damaged or there's a software problem, with my Sony STH30 the volume is very low. Even on the highest level its extremely low.

When connecting my Shennheiser HD 4.50BTNC with cable, the headphones are not even recognized.

If sound quality via wired headphones is important to you, I can't recommend you this phone. Sound quality is miles better on my old Mi A1.
[Xiaomi Poco X3 NFC Guides, News, & Discussion] PraneshSarangi:
I just bought a POCO X3. Indian version, without NFC. I was alarmed to read about the problem some people seem to be experiencing with the 3.5mm jack. So, that's one of the first things I tested with my headphones. I use the Sennheiser HD598 and Audio Technica ATH M50x. Both are working fine. I could hear the music loud and clear. When I installed the Hiby music app, it played my Hi Res DSD files, and the sound quality improved. I am a happy customer.

Has anyone tried ainur narsil.does the poco x3 have a quad dac.
[Xiaomi Poco X3 NFC Guides, News, & Discussion] humayun.bd:
From what I could gather on internet:

That hifi (24bit/192KHz) certification is only for the stereo speakers. The 3.5mm audio jack can't output hifi signals.
[Xiaomi Poco X3 NFC Guides, News, & Discussion] SkaboXD:
Not true, Poco X3 uses DAC from Snapdragon 732G which is HiFi certified. DAC name is WCD9375. Checked with HW Info app.

It can play up to 32bit 384KHz PCM.

Here is the official Qualcomm specification list: https://www.qualcomm.com/products/wcd9375

Also, I use ArrowOS with F1xy kernel and 3.5mm jack audio quality really improved compared to MIUI.

I can use Low Latency driver in Neutron Music Player without distortion while on MIUI sound is distorted and you can hear degradation in sound quality like some higher frequencies are taken out.
[Xiaomi Poco X3 NFC Guides, News, & Discussion] Berik84:
If you want a better audio quality on stock MIUI, remove the AudioFX app and the system sound enhancer app (where you can choose intelligent, music, voice etc.). It removes the awful processing even on external DACs.

EDIT: these are the packages I disabled: com.miui.audioeffect and com.miui.misound

Coming from redmi note 7, it's surprising to see audio from 3.5mm is quite good, on 12.0.8 update and using Spotify premium with my blon bl03, i am kinda liking it.

Depending on the ROM V4A can break the audio (aosp/lineage roms, not sure about miui), i recommend installing ainur narsil and audio modification library with it to solve it!
[Xiaomi Poco X3 NFC Guides, News, & Discussion] bacitoto:
This is so weird. I just bought some dt990 pro and they should be very hard to drive 250ohms.

But I can hear music just fine, and comparing to my pc+amp setup besides the volume ofc, there's only a diference in bass. But the quality is fine.

I have 12.0.8.0 QJGEUXM

Debloated a lot of apps

Have sound effects off, and sound preset set to smart

and I'm using Music by MaxFour

So not sure if this is a problem on some devices or just software/configs
[Xiaomi Poco X3 NFC Guides, News, & Discussion] SkaboXD:
Yup, quality od DAC itself is good. It's even better when you're on custom ROM without that crappy MIUI sound processing!
[Xiaomi Poco X3 NFC Guides, News, & Discussion] andrewtanch92:
Just want to say thanks to the top posts here.

I was quite appalled with the audio from them 3.5mm jack. Having a DAC setup to compare to on my pc, there seems to be some phase smearing and the spatial space was being tempered with on the Poco. Not as clean and not as wide, but it is punchier, which might be the audio profile Xiaomi was aiming for the masses

It was quite easy to uninstall the system apps were mentioned in post 53

1) Enable developer options > enable usb debugging > Download ADB Appcontrol to a pc (google it, download the zip and unzip)

2) Connect ur phone to ur pc, open the unzipped folder and open appcontrol, the phone will ask that u authorize ur pc for ADB

3) Search the apps mentioned in post 53 and disable them (I actually uninstalled them)

And wow the results for music are fantastic for me.

Appearantly the phone supports Dolby Atmos low-key, I'm not sure if doing these removes the Atmos from the dual speaker setup (can't test now as my Netflix account is having issues).

I know this from the 1st EP of Warrior Nun. A few minutes in when they are in the 'bunker' arguing or so, then some explosions and gunfire begin. The first 3 booms should sound like they are from front left > front side left > front rear left. The following gunshots too, that was amazing
[Xiaomi Poco X3 NFC Guides, News, & Discussion] yiidonger:
Not sure why the audio quality suddenly becomes so good.. no more distorted sound.. very good sound clarity like other phone.. decent soundstage.. but again, too much bass.. good for bass lover but not everyone like it..
