[Q] HD Voice support?

Out of interest does anyone know if the Nexus 4 will support HD voice? Is it a feature that requires baseband support or is it implemented in the system software?

Good question. I've currently got it on my Samsung Galaxy S3.
For it to work, you need all of the following:
- A handset that supports it (hardware-wise)
- A network that supports it (such as 3 Mobile in the UK)
- Software that supports it (The official 3 Mobile Samsung ROMs for the S3 support it, and CM10 supports it for the S3, but I don't know whether this was added in or part of Android 4.1.X natively)
- The call needs to be between two devices that meet all of the above.
HD voice is very impressive, though. It's like having the person stood next to you talking in your ear (which may or may not be a good thing, depending who you're talking to!).
I hope the Nexus 4 has it, it might possibly even be a deal-breaker for me if it doesn't.

Well, the baseband is a Qualcomm MDM9615 which should definitely support AMR-WB (the codec needed for HD Voice) so that's one part of the puzzle solved. Three definitely support it on their network, so the only question now is whether the phone's software supports it.

ja i have also tried to google that info... guess we have to ask the real google ^^ or LG?
really hope tht it will support HD Voice

Looks like the Optimus G also has it..?
So hardwarewise we are safe to go? CM 10 also does support it if i am not mistaken? would be strange if Android would not?
Also tried to contact LG but that did not help much. ( They at least assured me it is voice enabled and has got google now *facepalm*)

Forgive me if I am wrong, but isn't it the DSP that needs to support it? The QDSP6 does appear to support AMR-WB anyway, I just didn't think the baseband had anything to do with it, have I misunderstood?

The DSP responsible for implementing the codec is integrated within the MDM baseband chip, and from what I've gleaned the baseband does support it.

Still nothing on that?
Neither google nor LG replied..

Well I've got my Nexus 4 now, so I rang my wife on her Samsung Galaxy S III (we're both on the 3 network in the UK) and the call was in HD.
So the Nexus 4 does support HD voice!

I just posted a reply to another thread that I'm getting HD voice on my N4 as well.

T-Mobile HD Voice
I can't wait to see if it works on the Nexus 4 over T-Mobile in the US. They recently announced support but neglected to list the Nexus 4 on their supported devices, even though they sell the device in stores.

Let's hope they have a firmware update for the upcoming LTE network too.

It sounds like you're stood next to the person rather than being on the phone.
Technically, I don't know how you'd check in-call, there's no indication or notification or anything like that.

[Q] Bluetooth 4.0 Low Energy

Other flagships have hardware that support this - does the Nexus and is Android 4.2 likely to support it? (4.1 does not).
Why is it useful? Well if you use a heart rate monitor for sports, it will last longer. It can also be used to connect devices.
It's a huge feature for me as a runner. Currently I use a Garmin 305 which is an awesome, if ugly, product. With apps like strava / endomondo and more, it would be nice to have all this, with GPS and music on one device

I believe Bluetooth 4.0 is present on this device. Check the spec sheet on Google Play, but I'm 99.99% sure.

The hardware is present for Bluetooth Low Energy (BLE) but as yet, no version of Android supports it.
There is an issue thread on google regarding this - if people star it google might treat the issue as a priority.
http://code.google.com/p/android/issues/detail?id=33371
I think google is looking to NFC for nearfield communication forgetting some of the cool uses bluetooth can be put to.

The Broadcom BCM4330 supports BTLE (http://www.broadcom.com/press/release.php?id=s549642), and according to this website: http://www.ubmtechinsights.com/repo...market-reports/Report-Profile/?ReportKey=8713
The LG Optimus G uses that Broadcom chip, so it's possible that the Nexus 4 also uses it?
According to the newly updated Android 4.2 changelog: http://developer.android.com/about/versions/jelly-bean.html
Android 4.2 introduces a new Bluetooth stack optimized for use with Android devices. The new Bluetooth stack developed in collaboration between Google and Broadcom replaces the stack based on BlueZ and provides improved compatibility and reliability.

I sure hope that we will have BTLE support with the Nexus 4. I really want to buy a Polar H7 HRM!

I'm glad someone else is concerned
It doesn't look too good. Although they have rewritten the stack, there is no mention of Bluetooth Low Energy or Bluetooth Smart.
Apart from the issue raised with google in my first post, I have no idea how to reach out to them regarding this. Does anyone know? This is Android general rather than device specific. Pretty much all the new handsets have hardware that support BLE but there is no OS support in Android

At last - some hope. Although there is no ETA, looks like we can hope for BLE support in Android 4.3
"BLE will be the next major feature we are going to add."
https://groups.google.com/forum/#!msg/android-platform/CYtxCmtZ-WI/aIzBq7KbKVUJ

Any updates on the BLE support? I am working on a BLE breakout board and would like to get it working with the Nexus 4 rather than just the computer via a dongle. From what I've found online there is a BLE stack in 4.2, yet for some reason I can't find it or get anything to work.

What exactly would this do? I understand the low energy stuff, but I don't see what else it has, and whether we have to enable it first, or something.

BLE is a wireless protocol that peripheral devices can use to interface with your phone. Somewhat similar to regular bluetooth (and other proprietary wireless links), it can allow a sensor to wirelessly stream data or allow a phone to control a robot or any other device with BLE. I'm not sure if that answers your question. The real benefit is that BLE uses significantly less power (upon other things) and thus can enable a new set of devices. For example, part of my dissertation is a cardiac monitoring system which I would like to connect to my Nexus 4.

Any news?
Hi guys,
Are there any news on Bluetooth 4.0 / smart ready on the Nexus 4 and maybe 4.2.2 yet?
Was someone already able to pair the Nexus 4 with the Polar H7?
Maybe I'll order one and try if it works by now.
Thanks for your answers anyway. :good:

I have the same question about BLE.

Would love to play with the Stick-n-Find and/or Meterplug. And upgrade my Fitbit to the Bluetooth 4.0 version so I don't have to keep plugging that stupid dongle into my laptop.

Arrrghg - your post is what I found when searching for Fitbit, which I just bought. Very frustrating our N4's can't support the BT connection yet. I also hate that stupid dongle!

The new Fitbits use BLE too? Wow, Google need to get Android caught up, really never expect them to be behind with technologies.
So, should I send my H7 back, or wait???

Google finally started looking into BLE two days ago. See the bottom of this page:

I just bought a Fitbit One which uses BLE. I'm with you guys in hoping Google gets this feature added and supported very soon. It would be really nice!

This will be addressed with K release.

I wonder which one will come out first. The Fitbit Flex or a Nexus 4 update with BLE.

I'm hoping it's coming soon, I just ordered a bunch of Motes to instrument my house...

Moto X Play and Apt-X support?

Soooo...thought I put this on here just in case anybody else is wondering.
It seems the Moto X Play supports apt-X. I thought it did not and was kind of surprised to find out (if it is indeed true).
I went to capture logcat traces when pairing the Play with my Sony MDR-1ABT Bluetooth headphones to find out if it supports apt-X. Unsurprisingly, I wasn't able to find anything apt-X related in the logs. So I figured it does not support it, in contrast to myl old LG G2, which mentions negotiating apt-X in the traces.
Wanting to know for sure, I bought an Avantree Saturn Pro Bluetooth Transceiver, because it offers a status LED that indicates which Audio mode is used.
Much to my surprise, according to that little device, the Moto X Play paired using apt-X! To do a negative confirmation, I paired the Saturn Pro with my Laptop and my Dell Venue 8 7840 Tablet, both of which do not support apt-X. The Saturn Pro correctly showed this, as well as telling me that a Samsung Galaxy S5 and Sony Xperia Z5 compact both do support apt-X (no surprise there).
I'm curious if anybody else can confirm apt-X support, preferrably through some other device/test?

That has been already answered here

I can't test it for sure, but Motorola support also claimed it supported Apt-X as one of my questions before I purchased it.

Does S8/S8+ support AptX HD audio codec.

Do we have any reliable sources if new Galaxy S smartphone support AptX HD Bluetooth codec.
Thanks.

HD, not sure. Regular apt x, yes. Samsung has been using apt x since the s3 if I remember correctly.

Hey paatha13,
I have been wondering the same thing. I e-mailed [email protected] and didn't get any response, however, I noticed today that they have updated their website to list the Galaxy S8 and S8+. Unfortunately, while they are listed under aptX devices, they are not listed under aptX-HD devices.
Source: aptx.com
Click aptX Solutions-->aptX, then scroll down and select "See all products": the Galaxy S8 and S8+ are both listed.
Click aptX Solutions-->aptX HD, then scroll down and select "See all products": no Galaxy phone is listed.
This is disappointing since the chipset used by the S8 supports aptX HD. I know Samsung uses their own high-quality proprietary codec (they call it Hi-Fi) so that may be their justification for not implementing the new codec, however, that does not help in the likely scenario where the sink device does not support Samsung's codec but does support aptX HD.
Hope that helps,
Stevie Wonder

Can you output music to one device using the APT X codec while also sending music to an older A2DP device without issues? I am worried that the higher quality APTX device will dumb down to match A2DP with dual streaming. Anyone know if that is the case or not?
My car's bluetooth does not support APT X unfortunately and the audio quality isn't very good. Was hoping to buy a standalone APT X bluetooth receiver and stick it in my car somewhere connecting to my car with the AUX cable, and still retain vehicle controls for next/previous track. Figured I would dual stream to my car (with the volume off/low) and to my APTx receiver through aux to accomplish this. Also can both devices automatically pair and go into dual audio mode?

aptx is a proprietery algorithm that the manufacturer has to pay to enable. It cant be enabled by end users. It would be illegal even if someone figured out how to do it.

No all oreo devices support ldac. Sony and Google worked together to provide ldac support. ldac, aptx dont need hardware support on the phone side because the phones processor can do the coding and decoding. All of these can be done through software and sony has enabled ldac on all phones running oreo
It is the headphones that need hardware support for aptx and ldac.
ldac is sony's proprietary algorithm and since all oreo phones support ldac now, if anyone wants to use ldac headphones, they have to buy sony headphones.
Other manufacturers dont support ldac.
Consequently none of Sony's headphones support aptx since qualcomm owns aptx.
It is important to note all these ldac and aptx are different ways of transcoding music. The actual bluetooth hardware does not change. Only a software or hardware transcoder is added.

All Oreo phones could support it if Qualcomm allowed free use of aptX just like Sony does with LDAC on any device running Oreo.
It could be enabled with a simple software update.

Ok i tested with aptx headphones and mi A1 does not support this codec, only AAC. What a pity.
In fact I found out that the Snapdragon 625 does not support it, so it's a hardware limit before the software
