[Q] Galaxy S-IV (S4) confirmation for AptX audio

Hello,
As the title says , is there anyone who can please guide me for the following queries :
1. Does international Samsung Galaxy S-IV supports AptX audio compression for bluetooth audio streaming. I am a bit confused, although it is listed on the AptX website as a complaint device smartphone, some other places list only Galaxy S-IV Active as the complaint device. Would be nice to know which model variants of S4 support the aptx.
2. Would be nice to know about how to confirm that it supports Bluetooth audio aptX (any terminal or ADB command ? ), will this command even output the presence of aptX , even if the mobile is not paired to an aptX complaint device and actively streaming the audio. I am asking since I dont have an AptX enables bluetooth headphone or speaker at the moment, although I am researching prior to buying one.
3. If connected to an aptX complaint device , do we have to use the stock android ROM Music or Media player to get the benefit of aptX audio streaming. Or we can use any media player of our choice (like MX Player, Wondershare or even the ported Sony Walkman App) while running the stock ROM. I am running the stock WanamLite ROM 4.2.2 and prefer the ported sony walkman app for listening to music.
Would really appreciate the feedback and opinions for the queries, which are not only for me, but would help the community at large.
Thanks for your support.
So many views and not a single guru to advise and answer....surprising at the least....
Keeping the fingers crossed....
Pending my decision to buy aptx enabled Bluetooth headphones...till the queries are answered....hope these may help a lot of others like me.

Same doubt
I hace the same doubt in my case I do hace an aptx enabled headphones but I dont know if the feature is being used
I used S4 with an car adapter from htc and if i remember well the color from the led was different for the aptx/nonaptx. From what i know/remeber S4 has aptx.

Has anyone been able to confirm aptX support on the Note 4?
Yes it has. Official confirmation here http://gavinsgadgets.wordpress.com/2014/11/15/does-the-samsung-note-4-have-apt-x-codec/
Hi,
how do you know if aptx is working? is the codec compatible with third party music players or just the Samsung one?
is there any way we can see if it's on using the secret codes menu?
I have yamaha rxv1073 amplifier with aptx bluetooth receiver but it sounds the same to. me with this phone and my wife older iphone.
Thanks

run logcat and look for "aptx"
if it does not show some output with this text then it is not using it
you will need to catch it while connecting to the bluetooth device
How do you 'catch it' when connecting?
Should the phone indicate something about AptX?

AptX implementation on ZE552KL and chip support

Hi everyone,
Android O brings bluetooth audio codec option that includes AptX. Does 625 actually support AptX? Is there a way to verify this? I have an AptX ready headset, it isn't fancy by any means, but I intend to make use of the feature. It's probably gimmicky but let's give it a shot.

This is screenshot of connected devices in action.
@sanctitude:
Which app does the notification about runnig "BT aptx codec" on your screen shot come from? How can i show that on my device?
You can find it on developer option, scroll down to bluetooth section where you can select your codec
Thanks, santitude!
I know about the "developer option" for the general setting of apt-x for BT but this is not the same thing as your screen shot.
Your screen-shot above is apparently a notification about the "running" codec, being actually used at the moment of playing music through BT.
On my device on LOS 15.1 i do not see a notification as on your screen shot, but this is exactly what i'm looking for.
I'm on stock Oreo, the notification just showed up during playback using aptX headset, it's probably OS related or behaviour. Anyone using LOS, please clarify

Bluetooth aptX not working

Hello everybody!
As I know our Nokia 5 (Android 8.1) supports Bluetooth audio codecs like AAC or aptX. So I want to use my Anker Soundbuds Sport IE20, which also supports aptX.
The problem is that I can choose aptX in the developer options and I can use it too. But I must choose it everytime if I want to hear music with my BT-headset. When I choose it, it works and I hear a difference to SBC and the same when I choose AAC.
So I want to ask you why my Nokia 5 doesn't choose aptX automatically, because it should do that (as I know)?
I hope somebody can help me with that
Edit: With my old Samsung Galaxy S5 it works perfectly without any problem.

Bluetooth codec question. DO you have LDAC on your phone?

Could anyone with the phone double-check their bluetooth codec options?
Being Android 8.1.0, it should have LDAC ... and that is extremely important to me. But it's missing from my phone. I have tried installing JamesDSP through Magisk, and it works, however I do not see how to enable its LDAC so its running everything through SBC or whatever that low-quality sounding codec is called.
Thanks.
Brian
I also wondered if such audio drivers like LDAC enabling is similar to having 4K 265H codec built in to the chipset & not a question of software updates can enable.....
