[HOWTO] Finally! a REAL solution to disable noise reduction

[tarobun]

In some (most?) roms, you can turn on and off the noise reduction during a phone call by using the menu button - menu option is called "Noise Reduction On/Off". With the noise reduction "on" the icon is shown, when it is "off" the icon disappears.

The reason I said "some roms" is because I couldn't see that option in the CheckROM RevoHD™ V6.

You can only change the noise reduction during a phone call, not while dialling or ringing. Although you can turn it on/off during the call, it will not remember the state... it will always start "off" (the original Phone.apk will always start "on").

And no, I didn't delete anything. Just changed a 1 ("on") to a 0 ("off"). The smaller apk size is due to the compression of the classes.dex.

I used the hex editor 0xED for Mac OSX.

Thanks a lot for your help

tarobun - many thanks for your work on this. Tested and it works. My only mistake was trying to edit the hex file for the phone.apk instead of the phone.odex file. Duhhhh!

Hello tarobun,
just installed stock ICS XXLPQ , and in new Phone.odex i'm unable to find string 32 84 2F 00 12 13 .

Would it be possible to fix ICS Phone.odex?
Thanks

You can activate the noise suppression in my dialer?
Here is the link above to post, thanks in advance!

Most ROM have a slightly different version of Phone.apk so it's best to modify the one that came with your ROM.

Having said that, the fix is very simple (just changing a 1 to a 0) so you could hex-edit the apk/odex directly... how good is your hex editing skills?

To make the changes via hex editing, do the following:

For odex ROMs:

1. Download the Phone.odex file
2. Open in hex editor
3. Search for the bytes: 32 84 2F 00 12 13 (there should be only 1 match)
4. Change the last byte to 03
5. Save and upload Phone.odex to /system/app
6. Reboot

For dexodex ROMs:

1. Download the Phone.apk file
2. Extract the classes.dex file (unzip Phone.apk classes.dex)
3. Open in hex editor
4. Search for the bytes: 32 84 2F 00 12 13 (there should be only 1 match)
5. Change the last byte to 03
6. Save and add classes.dex back to apk (zip Phone.apk classes.dex)
7. Upload Phone.apk to /system/app
8. Reboot

Otherwise upload your Phone.apk and I'll make the change for u.

Hello and thank you for your edit . I would also change the file phone will ask you some info I have is phone.odex the file , the file phone.apk with the green phone icon ... which of these files should I change ? Ginger is the rom 2.3.6 . KK2 poland .

Once changed just plug it in / system / app and overwrite the original after backing up ?

for ICS 4.0.3 you will have to search for 10 01 22 00 D6 and replace 10 with 20

smali :

.method private onPhoneStateChanged(Landroid/os/AsyncResultV
...
invoke-static {v0, v1, v1}, Lcom/android/phone/PhoneUtils;->turnOnNoiseSuppression(Landroid/content/Context;ZZ)V

second parameter has to be modified to v2:

invoke-static {v0, v2, v1}, Lcom/android/phone/PhoneUtils;->turnOnNoiseSuppression(Landroid/content/Context;ZZ)V

FYI...If you want an echo-free ROM go for CM9, as it doesn't have NR implemented yet, hopefully never.

Or, you could follow these directions (http://xdaforums.com/showthread.php?t=1441510). If it works, then you can use whatever ROM you want, with or without NR.

I did this, and now with NR defaulted on and a case on the phone, no echo.

I used to have a modded phone with NR defaulted off, but I decided that one of the features of this phone that I paid for was NR, so I wanted it working.

hello tarobun
I really appreciate you if you can update your string value for ICS odex roms because after I updated to ICS again suffer from this problem and don't want to use some physical way to open my phone and the code don't exist on official ICS roms

thank you so much

The answer has already been provided by firero

smali :

.method private onPhoneStateChanged(Landroid/os/AsyncResult; )V

second parameter has to be modified to v2:

invoke-static {v0, v2, v1}, Lcom/android/phone/PhoneUtils;->turnOnNoiseSuppression(Landroid/content/Context;ZZ)V

But search for just 10 01 22 00 and change first byte from 10 to 20.

Worked finally ICS !!!

excellent work! outstanding!!

thank you so much !
according to firero post I searched 10 01 22 00 D6 before and found nothing .
but after I search only 10 01 22 00 I finally found It .and I found there is a D5 in end of string not D6.
thank you again man. you are my savior!

hello diavolo
this is the steps already mentioned in this topic to how set default noise reductions OFF in phone calls. dont need to disable it each time in each phone calls. you can use http://www.mediafire.com/?dbwgi2dded8bt7a for Hex editing and take attention to always backup your original files . read this topic from beginning and you will get it. if didn't get it then say what is your exact problem

hello again,
I used the way in post 74 for GB stock rom and post 131 for official ICS rom it worked good.
but for some reason I came back again to latest GB 2.3.6 UHLB2 but deodexed by wanam(stock rom). Again have trouble:
1. the string 32 84 2F 00 12 13 not exist in classes.dex (extracted from phone.apk)
2. I extracted classes.dex with winrar from phone.apk but dont know how to Save and add classes.dex back to phone.apk?? (I mean how to repack new phone.apk with new classes.dex with winrar??)
please guide me how could it be done
thanks in advance

Sorry to Hijack an old thread but I've been trying to solve this horrible issue since getting the phone. It's ether open it up and remove the second mic (killing the speakerphone) or just giving up and getting another phone.

Tarobun your posts have been of great help to at least TRY to fix this!

I tried hex editing the phone.apk (and following the java checksum) on my deodexed rom but it seems to have done nothing. Testing by simple means of calling another number, playing speech through the bottom mic and any sound at the top mic still affects it horribly.

Android 2.3.6, BB I9100XXKI4, Siyah 2.6.35.14-DarkKnight v2.3+

I never had the option on mine when in call to turn the noise suppression off, a friend has a stock device with carrier branded firmware and has both an in-call option and the squiggly icon present.

I have two phone.apk's that are supposed to work with this rom, neither give me the in-call option. One has "record", the other has "add call"

I did also try to copy across the Phone.apk, Phone_Util.apk, PhoneCrashNotifier.apk, PhoneErrService.apk from a RomKitchen rom that DID have the option to no avail.

What I did find curious was when I DID install the RomKitchen ROM (which drank battery) and subsequently ODIN'd the official carrier branded firmware that my device came with back on it, the noise suppression option was still present. Once I'd done a full hardware reset however, it was once again gone so there must be some other hidden setting that enables the presence of the selectable noise cancelling user interface.


I would attach the files but I can see only valid extensions but no upload button, might be because I'm "new" even though I registered when this site was dedicated to my HTC Wallaby (Qtek 1010)
