my friend has an xda II & he bought a Jabra 250 BT headset, he have no idea how to use it & moreover i never had BT in any of my phones so both are ignorant regarding BT, now he asked me a question, "How can i dial a contact from my Headset without the use of the phone, is their any SW i need to use?" i tiold him, i have no idea but i will forward his question to this forum, so could someone answer this question pleaaaaaase ?
the point is the right BT profile ... the headset profile doesn't work except during a phone call ... what you need is a "hands free" profile which will deal with all types of system "sounds" ... then you can use MS voice commands s/w ... however, I didn't try this myself, but in theory it should work
I have this combination. I've not checked the groups recently but from personal experience you cannot dial from the headset with the exception of a bolt-on (name escapes me) that will allow you to use the headset button to redial the last number.
I also have Microsoft voice thingy which works well but you need to initiate the call from the pda and then switch it over to the headset once connected. This little bolt on does manage the operation of the bluetooth radio and disables it to save battery after one minute. If you want to initiate a call like this then it is best to kick the bluetooth off first otherwise there is a delay before the headset links up and the person you just called is left hanging around whilst you frantically try to transfer the call to the headset!
Having said that and with all its limitations the two do work well together. One thing I did do based on various comments on this web site was to update my firmware to latest version.
Hope this helps
I am having a strange problem with incoming calls.
The voice quality is very bad with the other persons voice being "metallic".
However, no such problems in outgoing calls, and other people can hear my voice fine.
I called up my network operator, and they tell me I need to switch off "Clear voice" setting in my phone.
However, I went through all settings, and there is actually nothing with this name.
So is there such a setting?
If not, can I try upgrading to latest firmware. Actually, I have not updated my froyo (I am still on 10b), as I do not want to loose capability of rooting.
I think latest is 2.2.2 (10e). I am not sure if its rootable.
Any ideas?
I don't think there is such option in optimus one, try to switch to 3g network if you use 2g, but compared with other phones my optimus one output sound quality is bad. I don't think that you can do anything but if you find a way to improve sound quality let me know.
do you experience background static noise? because I cand hear a background buzzing noise everytime the sound is on.

Ask to talk to someone technically savvy who knows WTH are they talking about next time. There is no such thing anywhere and frankly I do not recall any mobile phone that would have such thing like "clear voice".
2g and 3g have nothing to do with voice quality... oh, and the background static is a bug of all O1s, unfortunately.
Voice quality is dependent on the price of the device, so a budget phone generally means poorer quality... only Nokia had perfect reception on their low-end models... just my 2 cents.
Maybe that operator got his features mixed-up and he was referring to HD Voice - I know Orange launched it in a few countries, but that's a whole other thing.

Ah, speaking of HD Voice, do you think devices NOT bought from Orange could use it?
Also, have you noticed that, during calls, there seems to be some form of noise reduction going on? If the person you are talking to is in a quiet(er) environment, and they stop talking, the speaker goes completely silent, whereas when they are talking you can hear the normal (IMO) GSM background noises.

Actually, many devices support it at this time, since it's a codec-related thing and not a hardware one (and it's not proprietary to Orange, it's a standard that will be implemented in time)... It's rather tricky to make an assumption about your O1, since I really have no clue if the appropriate codecs are included on our phones, if they are activated etc.; just ask someone from Orange (although I'm sure that most will not know the answer).
Here's a very interesting article detailing HD voice tech, written by Eldar Murtazin: http://www.mobile-review.com/articles/2010/hd-voice-en.shtml.

Yeah, that's normal, I have encountered it on many phones... it's probably related to the passive noise cancellation algorithms our devices use (where they try to make out what part of the sound received in the mic is the voice and which one is the ambient background). It's a really long discussion, since when the mic receives a sound lower than X dB it cuts it out, then as soon as it detects a more powerful sound it applies a kind of gain (hence the static) and so on.
Oh, note that these are all more like educated guesses, but I think they're pretty correct.
Now, with active noise cancellation... well, that's just another world! (I had the pleasure of a few conversations with a phone that supported it)
There is no static.
Its just that, from some networks(not all) when I get incoming call, the voice is "metallic" and keeps breaking, even when signal is full.
So its impossible to have a conversation.
I guess its a problem with my network operator then.
In Hidden Menu (3845#*500#), under
DEVICE TEST->SOUND TEST-> VOCODER are the settings that affect noise reduction and bad call quality but I do not know what parameter disables sound processing on calls.
Also on page no.55 in service manual, there is this text and I hope that it can be useful to someone with greater knowledge to change parameters and turn off noise suppression, and that stupid hiiiisss sound during call.
3.13.2. Audio signal processing & interface
3.13.2.1 MSM7227 audio interface
The MSM7227A audio front end comprises the stereo wideband codec, PCM interface, and additional DSP
audio processing. The stereo wideband codec allows the MSM7227 device to support stereo music/ringer
melody applications in addition to the 8 kHz voice band applications on the forward link.
In the audio transmit path, the device operates as 13-bit linear converter with software, selectable 8 kHz and
16 kHz sampling rate. In the audio receive path, the device operates as a software-selectable 13-bit or 16-bit
linear converter with software selectable 8 kHz,16 kHz, 22.05 kHz, 24 kHz, 32 kHz, 44.1 kHz, or 48 kHz
sampling rate. Through software, the Rx path can be configured as either a mono or stereo output. New to
the MSM7227 device is a transmit (Tx) ADC path that now supports stereo wideband sampling. The
integrated codec contains all of the required conversion and amplification stages for the audio front end. Th
codec operates as a 13-bit linear codec with the transmit (Tx) and receive (Rx) filters designed to meet ITU-T
G.712 requirements.
The codec includes a programmable side tone path for summing a portion of the Tx audio into the Rx path.
An on-chip voltage/current reference is provided to generate the precise voltages and currents required by
the codec. This circuit requires a single capacitor of 0.1 μF to be connected between the CCOMP and GND
pins. The on-chip voltage reference also provides a microphone bias voltage required for electret condenser
microphones typically used in handset applications. The MICBIAS output pin is designed to provide 1.8 V DC
while delivering as much as 1 mA of current.

Hi, xda-developers!
I'm curious to whether my phone has something faulty going on, or whether it's the same for everyone. If I decide to load up a sufficiently long youtube video (anything that requires you to keep buffering with the network, really), if I decide to watch it during this time, I get a static noise in the background. The noise volume level doesn't change when you lower the media volume, until you have made it silent, and it keeps making the crackle for a few seconds, then stops.
Android 2.3, prerooted image.
Should be added that I have to use my inear headphones to make it audible, it's not that loud. Found other people having the same problem, unable to link since I'm only at 10 posts, but can quote that:
Yes I've had this issue too, it's especially noticeable when listening to music via Connected Devices (i.e. over DLNA) but not so bad in Music Player. This might suggest Wi-Fi interference possibly? I might do some tests with the phone in Airplane mode...

As well as on: http://forum.xda-developers.com/showthread.php?p=27128237#post27128237
I am developing a sound level meter app for Android. (I use standard AudioRecord and then process the buffers with JTransforms FFT to get the amplitudes and eventually calculate the dBA value)
My app is currently working very well (I have compared it to a real SLM, and I have tested various devices)
Currently I am having the following device specific issues: (Take note that I am recording with an external (AUX) microphone)
- Samsung J2 (J200H): The dB does not step correctly.. In a certain range, if I step the noise down 5dB it goes down 5dB, but in some ranges it steps 10dB when I step down 5dB. I have recorded the audio and by measuring the recording I can see it not stepping correctly, which means that the fault is happening on the device level, and not my app. I have two other J2 models (J200G & J200F), on both of these it is working perfectly. Any ideas what could be causing this? Where should I look?
- On Xiaomi devices (Redmi Note 4 & Redmi 4A) it seems like there is some kind of Automatic Gain Control enabled. (getEnabled() for AGC returns false). When presenting a tone the dB reading goes very high, and then after about a second lowers by 10-20dB. If anything in the audio changes it "jumps" again and then lowers again. Once again, I can hear the effect when recording a tone - the tone starts high and then lowers, even though there is no change in the source.
Any help would be greatly appreciated as I have no idea how to move forward...
I gave information about the subject by calling the customer service, but over a period of more than fifteen days, the return could not be provided. Topic; When a wired or wireless headset is connected, or when we are connected to the car kit via Bluetooth, the incoming notification sounds do not come from the device itself. It must be in music listening mode when connected to the headset or the vehicle. Otherwise, you do not notice the incoming notification. I'm a very busy phone user at my workplace, the headset at the end of the conversation with the headset at the end of my ear when I leave it on the table and the phone does not receive notification sounds, some mail, message or whatsapp alerts only when I look at the device. In this case, there is an application that manages where the ringing and notification sounds will come out when the headset is connected in the rival manufacturers. I would ask your software and application developers to conduct a study on the subject.
Please help him with this.
Hola
The issue you are describing happens to me as well. Not sure if this issue is recent with newer firmware updates. There is no resolution that I know of.

it's not an issue, it's just the way Huawei chose to implement it. I'm also used to get notification sounds on the phone while driving and having it connected via Bluetooth but since i got my mate 20 pro i'm always checking my idrive screen to see if i received a message ....
