After a couple phone calls I can say that this does improve call quality on both ends by a huge amount. People are saying I sound much better and they sound much better.
[EVO 4G Q&A, Help & Troubleshooting] xavier1022:
First cs reps don't know jack...ask To be transfers to evo tech support..tell them you are trying to change from evrc to evrc-b...they will then provide you with msl code which is apparently top security.. Essentially this setting change is like changing channels on the network..if this is worst for you just revert to original evrc...

Thanks for figuring this out everyone. The instructions i posted are from the incredible forum and those exact instructions did work on the incredible.

Thanks again.

[EVO 4G Q&A, Help & Troubleshooting] entropism:
##786# is RTN, not SVN. As in, it returns the phone to it's original state and wipes everything. Just so nobody accidentally does this.
[EVO 4G Q&A, Help & Troubleshooting] maedhros77:
Just FYI, you can also find this setting, and modify it, by using ##3282# > edit mode (enter MSL)> advanced. There is a setting for EVRC-B that is defaulted to disable, as well as a Home orig and roam orig, that you can change to EVRC-B.
[EVO 4G Q&A, Help & Troubleshooting] strung:
I can't tell a difference between any of the vocoders.

In theory, I believe 13k should sound better than EVRC-B (assuming you have a decent signal). EVRC-B is still an 8kbps codec, but the 13k codec has 62% more bandwidth.
[EVO 4G Q&A, Help & Troubleshooting] frifox:
128Kbps AAC is comparable to 192Kbps MP3... More bandwidth != better quality.
[EVO 4G Q&A, Help & Troubleshooting] danknee:
##786# puts you into the reverse logistics support menu with your phone's info. From within this menu, to master reset you have to push menu >> reset >> enter your MSL and click OK.

Just saying, so nobody is afraid to explore. You won't reset your phone by mistake unless you are entering your MSL at prompts you don't understand (please don't).
[EVO 4G Q&A, Help & Troubleshooting] clockcycle:
Dial ##3282# on your dialer

Choose Edit

Enter Your phone's MSL (call Sprint CS and ask for yours)

Choose the Advanced option

Did anyone edit the EVRC-B (enable / disable) option, as well?

[EVO 4G Q&A, Help & Troubleshooting] synplex:
So just to confirm does this change work with Sprint's AirRave? ANyone try it out?
[EVO 4G Q&A, Help & Troubleshooting] EtherealRemnant:
The vocoder is set by the network. Currently Sprint uses EVRC and will automatically set the phone to EVRC when you connect calls. I know for a fact that voice13k won't work but I'm not positive about EVRC-B but I'm pretty sure Sprint only uses EVRC...
[EVO 4G Q&A, Help & Troubleshooting] synplex:
Will this affect battery life for the better or worse? Will it cause my phone to search for signal more or something like that?
[EVO 4G Q&A, Help & Troubleshooting] EtherealRemnant:
No its just the voice codec that the phone uses for phone calls. It directly affects voice quality and nothing else.
[EVO 4G Q&A, Help & Troubleshooting] synplex:
Well if that's all it does why not have it set to EVRCB automatically? :confused:
[EVO 4G Q&A, Help & Troubleshooting] EtherealRemnant:
Because Sprint does not use EVRC-B on their network. For a vocoder to work, both sides (phone and network) must support it.
[EVO 4G Q&A, Help & Troubleshooting] zackdadams:
I used this method.

I called Sprint (*2). Immediately asked for Evo Tech Support. I told them I wanted to increase my sound quality, and wanted my MSL #. They promptly gave it to me. Calls are now much clearer.
[EVO 4G Q&A, Help & Troubleshooting] akarol:
You can always change it back to what it was before in case you don't notice much difference right?
[EVO 4G Q&A, Help & Troubleshooting] Geniusdog254:
Yes. Same method. Just set it back to EVRC
[EVO 4G Q&A, Help & Troubleshooting] topdnbass:
I might just try this :D.

In theory it should sound better because EVRC-B is the newer generation.
[EVO 4G Q&A, Help & Troubleshooting] EtherealRemnant:
I changed a few things... I set my SCI at 4 to increase battery life (less tower polling), turned EVRC-B on for both home and roaming, and changed my ACCOLC to 2 (higher priority on towers for phone calls).
[EVO 4G Q&A, Help & Troubleshooting] wase4711:
How did you enter those menus, if I may ask?

thank you
[EVO 4G Q&A, Help & Troubleshooting] acrh2:
SCI of 4? Isn't that like checking the tower every 20 sec?
[EVO 4G Q&A, Help & Troubleshooting] EtherealRemnant:
##DATA#, Edit, enter MSL, then choose Advanced. They are all there.

10.24 actually. And I am thinking about raising it higher. I live in an area that has exceptional Sprint coverage so I'm not terribly concerned about the tower polling time.

And Sprint definitely supports EVRC-B because there is a HUGE difference in call quality - it sounds crystal clear like a landline or HSPA phone now.
[EVO 4G Q&A, Help & Troubleshooting] acrh2:
How does the coverage affect the time delay between checking towers for new incoming calls?
[EVO 4G Q&A, Help & Troubleshooting] wase4711:
THANK YOU so much for these fixes..I can't believe how clear, and absolutely interference free this phone sounds now..I did it on both my wife's and my EVO, and calling each other it sounded like we have a direct connection between us..

We too have a very strong Sprint signal in the SW suburbs of Chicago, so hopefully this will work everywhere in Chicagoland!
[EVO 4G Q&A, Help & Troubleshooting] EtherealRemnant:
I don't care about incoming calls. I mostly use my phone for data or outbound calls. So I don't care.
[EVO 4G Q&A, Help & Troubleshooting] acrh2:
But surely you realize that your post could possibly bring a lot of headaches to people who might try your settings?
[EVO 4G Q&A, Help & Troubleshooting] EtherealRemnant:
Eh. 10 seconds isn't that bad but it saves a LOT of battery life.

###Disclaimer - setting your SCI above 2 increases the amount of time it takes your phone to ring when someone calls you because it increases the time period for the tower to be checked for phone calls.###

Better?
[EVO 4G Q&A, Help & Troubleshooting] acrh2:
It will save very little battery, if any. If you google SCI, I believe there was a post on android central or something like that, where they measured the savings from SCI > 2. These savings were negligible.

Think about it this way. Your cell standby is about 50% of total battery drain in standby (and about 50% phone idle or so). If you drop 5% battery charge every 8 hours in standby, in going from SCI 2 to 4, you just saved 1.875% of battery charge for 8 hours.

For a 24 hour cycle, you would be saving about 5.6% of battery.
[EVO 4G Q&A, Help & Troubleshooting] MadhouseMedic:
Anyone who is saying placebo, i have an easy way for you to prove that it very well isn't.

Set it to EVRC

Call (303) 499-7111 (NIST's WWV Telephone Time Line. It is a 24/7 Automated Broadcast Of WWV's Shortwave Time Tones. Listen To It For A Full Minute To Hear The Voice And All Of The Tones.)

Set it to EVRC-B

Call (303) 499-7111

I did it, it worked.
[EVO 4G Q&A, Help & Troubleshooting] EtherealRemnant:
Considering how abysmal the battery is... anything helps. Also I'd like to see this test done on the Evo or the Incredible because I can almost guarantee you the battery savings would be a lot higher than that.

[EVO 4G Q&A, Help & Troubleshooting] acrh2:
I cannot tell if there's a difference. The call quality seems to vary from call to call even with the same settings.

I did get 3-4 calls to two different numbers with crystal clear quality.

The settings were either (both worked):

1) EVRCB - off

EVRCB home - on

EVRCB roam - on

2) EVRCB - on

EVRCB home - on

EVRCB roam - on
[EVO 4G Q&A, Help & Troubleshooting] wase4711:
so, is using 13k yielding even better clarity for anyone than using EVRC-B?

Using EVRC-B in all 3 Places yields some really crystal clear voice calls for me..

and, with changing the SCI to 4, I didnt really notice ANY difference in how long it took a call to be received; maybe went from 2 seconds to 3 seconds, no big deal..
[EVO 4G Q&A, Help & Troubleshooting] topdnbass:
We need to do some tests to see how things are affected..

So far i've set EVRC-B to enable

I'm not sure if it's necessary to enable it though.. Sounds like common sense.

Home Orig+Roam Orig to EVRC-b and SCI to 3..

Wait.. Are we setting it to 13K Voice now? or EVRC-B? Which is better?

I wish we had a sprint employee chime in with some info about some of these settings..

For example why is USB charging disabled by default in ##DATA#?
[EVO 4G Q&A, Help & Troubleshooting] dwntwnall4u:
Finally! Thank you. I tried this and it actually made a difference. The quality got better and also increased the volume. This was the reasons why I was going to cancel before the 30 days. I guess I have to just keep the EVO and Sprint.:)
[EVO 4G Q&A, Help & Troubleshooting] wase4711:
Quick Question:

which is a better option for the EVO; CDMA Only or WCDMA only?

I'm in Chicago, a very strong signal area, so the phone never really roams.

I have read that WCDMA only will really help extend battery life, but some say it makes no difference..

Thanks for any input on this!
[EVO 4G Q&A, Help & Troubleshooting] akarol:
So what's the consensus?

EVRCB vs. 13K?

Change SCI to 4 vs. battery life?
[EVO 4G Q&A, Help & Troubleshooting] wase4711:

[EVO 4G Q&A, Help & Troubleshooting] seventyfive:
This worked for me. I can easily hear a difference and my friends also notice it when i call them.

From Wikipedia

EVRC-B is an enhancement to EVRC and compresses each 20 milliseconds of 8000 Hz, 16-bit sampled speech input into output frames of one of the four different sizes: Rate 1 - 171 bits, Rate 1/2 - 80 bits, Rate 1/4 - 40 bits, Rate 1/8 - 16 bits.

In addition, there are two zero bit codec frame types: null frames and erasure frames, similar to EVRC. One significant enhancement in EVRC-B is the use of 1/4 rate frames that were not used in EVRC. This provides lower average data rates (ADRs) compared to EVRC, for a given voice quality.
[EVO 4G Q&A, Help & Troubleshooting] akarol:

You people are going to start missing a lot of phone calls if you start messing around with this.

Slot index checks how many times the phone checks the tower for cell calls.

Go to the instinct forums and see how many people have screwed up their phones from doing this.

Did a factory reset too to get it going. I'm pretty sure its because of messing up with the data panel. Sprint said to warn anybody else not to mess with these unless they really know what they are doing. It is a network issue that has yet to be remedied except for a manual reset.
[EVO 4G Q&A, Help & Troubleshooting] drmacinyasha:
Ok, so I did some experimenting today, and here's my results:

It's not that changing the settings which causes the problem with streaming apps, but merely opening the settings program for ##DATA# which causes this.

So, my recommendation:

1) Nandroid backup

2) Get MSL from Sprint

3) Change settings of your choice

4) Reboot into recovery

5) Nandroid restore

6) Repeat as desired until you're comfortable with the settings

I wonder if Sprint realizes the full extent of this bug... Anyone care to verify my findings?
