simply uninstalling the diagnostic app and recreating it via dialing ##634# would revert it back to its original version.
[Focus General] ricky119:
I think there MUST have something updated and improved in the new version, so let's hope we can find it out
[Focus General] dead_on_the_floor:
only thing I noticed about the update is that the initial diagnostic screen vibrates upon keypress. Everything else looks the same. Perhaps it saves settings correctly for some of those who were reporting settings reverting after restart.

Is there anything in the Diagnosis settings that will improve my bluetooth connectivity with my car's bluetooth system? I have the same car (Acura TL) that I had with my Fuze, and the bluetooth connection worked great. With my Focus, the bluetooth connection is lousy at best, and will often drop the connection (not the call, just the phone connection to the bluetooth system). Thanks for any help.

So I've gone through and done the volume enhance trick through the diagnosis menu. I've done it for both speakerphone and inline headphones which seem to both work in boosting volume. However I'm primarily using bluetooth headphones and the volume is still lacking. Any of you more technical guys have any idea if I can boost the bluetooth volume using this method, and if so, how to go about doing that? Thanks

BT Volume WEAK

Same here - to get reasonable volume out of BlueTooth on either my Moto S305 headphones or my Kenwood Deck in the car, I have to set volume on the phone to around 25 or greater. Using speakerphone or wired headphones, 25 is EXTREMELY LOUD! Usually 15 is fine with wired h/p.

Would love to find a setting to up the BT levels....

i have sort of a noob question. i just started to explore the diagnostic app (which works ok for me now)

My question is that most of the locks in my lock status shows disabled on my focus does that mean that it's unlocked?

SIM/USIM Lock: Disabled

Network Lock: Enabled

Network Subnet Lock: Disabled

Done...

any help would be much appreciated.

I assume you would have to disable the network lock to unlock the device. It looks as though you need two codes to do so: MMC/MNC and an NCK. anyone know what these codes are???

Can someone give me a clarification on hspda/hsupa? Is it essentially hspda=3G, hsupa=4G, or is hsupa sort of in between 3G and what ATT markets as 4G?
[Focus General] amlwaycooljr:
As far as I can tell hsdpa and hsupa are generally the same thing. hspda being for downloading (where the D in the acronym stands for downloading) and hsupa is for uploading (U being of course for uplink .. or basically uploading) max download speed is 7.2 mbps or 3G+ its a little better than basic 3G but not nearly 4G speeds currently rated in the 20 - 40 mbps range.

From the root menu (*#197328640#):

1: Debug Screen

8: Phone Control

7: Network Control

2: Band Selection

Within Band Selection, you'll have 3 options:

1: Automatic (default)

2: WCDMA Band Preference

3: GSM Band Preference

I go into 2: WCDMA Band Preference, then select 6: WCDMA ALL. Then hit the End button and Home out of the diagnostic app.

However, I have found that this keeps the phone from recognizing the GSM (2G/Edge) bands entirely. If I go into an area that has no 3G coverage, I have to go back into the menu and set it back to 1: Automatic in order for it to start selecting its own bands again. There are options squirreled away in the diagnostic menu which relate to the gains involved in what I think are how the phone selects bands, but those are above my head and I haven't bothered to mess with them as of yet, as I tend to desire to always force 3G anyway.

[Focus General] boah78:
anybody know what 'dualmode improvement control' does? I was fairly disappointed with speed gains I had gotten from just changing 'RRC control' but after I changed the 'dualmode...' to 'on' my speeds improved dramatically. I didn't think it would really change anything (my hunch was the 2 modes the name implies referred to the utms/gsm setting) but after the improvement I got I started to wonder if it has to do with changing between the 850 and 1900 mHz bands (or whatever it is AT&T uses). Service here has always been fast outside with full bars, but after changing this I'm getting similar speeds indoors (and showing 4-5 bars instead of the 2 I used to get) Last night I had to do a hard reset to put in a memory card, so did 5 tests each of right after the reset, changing only the rrc control, and then changing the dualmode improvement control. From beginning to end was about 30 minutes, and it was about 4 in the morning, so network traffic was probably minimal. The fastest results were:

right after the refresh, download 976 kb/s upload 211

after changing rrc contol dl 1130 upload 562

after changing dualmode dl 3421 upload 1489

all 5 tests were fairly similar in each group (5-10% difference or so)

The only weird thing is the original setting is "not active" and you can change it to on or off... I changed it to on first, and then off and got pretty much the same results, which kind of makes me think twice about whether it did anything. I don't really want to do another hard reset to get back to "not active" so I was hoping maybe somebody already knows what this setting does, or maybe someone else wanted to try changing it and seeing if they see similar results?
[Focus General] SuperSport:
Holy Cr*p Batman! I now have a SOLID 4 bars inside where I normally have 1 and if I'm lucky 2. My speed increased ever so slightly, 10-15%, not the large gains you mentioned, but it DID speed up. Best of all is the stronger signal. My house is notorious for bad signal on ALL phones with ATT. T-Mobile and Verizon are quite strong here. Just a bad area for my tower I guess.

Now I hope it does not hit the battery too bad. I'll try to keep an eye on it.

Dual mode allows for analog and digital signals.

[Focus General] SuperSport:
Ok, been running it for a little while. Speed increase still present, but bars are now a steady 3-4. Still a whole 2 bars better than before, but a slight drop. Although, it just started snowing, so maybe that is playing into it.

For those who want to try this (at your own risk), here's the down and dirty:

Use *#197328640# to get to the Main Menu.

1. for Debug Screen

8. for Phone Control

3. for NAS Control

6. for DualMode Improvement Control

1. to turn it ON

END

Reboot

:)

Remember, it only works on the original Diagnosis App. If it's been updated, uninstall it, then on the Phone Dialer, type ##634# to reinstall it.

[Focus General] boah78:
yeah, I went ahead and did a reset cause I was bored... the speed increase between my 2nd and 3rd set of results was more in line with yours, not because it's slower now, but my 2nd set was faster, so I think the first time I just got really unlucky with my results on the second time. still noticeably faster but more in line with what I would think I'd get from just having a better signal. Again got the jump to 4-5 bars inside all the time.

Today was the first full day since I changed it and there was no noticeable negative effect on battery life. Going on 12 hours off the charger now and the battery meter is still either 1 or 2 notches off of full (still getting use to the phone and can't remember how many different "frames" there are for the battery meter) If anything, I'd say having a stronger signal may have helped battery life.

I changed the 3g symbols to see if this is correct , so when I have a 3g network , it does change from the 3g to h (i changed it to 4g for fun) , but it only does this in big cities, and it doesnt last long enough to notice an increase!

Hey man, you're right this has made a huge improvement. I never got more than 2 bars of 3G at my house with any ATT phone. I complained so long that ATT gave me a free MicroCell 3 weeks ago.

I saw you suggested this to the guy that posted about giving his phone back after two weeks. And my name to the testimonial. I'm about to go out, I'll report if I get 3G+ or H icon.

I'm not sure how to use these number commands. When I press ##634# from the phone pad, do I then press "call"? And if so, how do I enter the various function code settings? When I tried to press ##634# from the phone pad then pressed "call" the keypad came up again, but no other buttons or commands.
[Focus General] gotvet:
Updated info - I read ALL of the diagnostic app posts and realized that dialing ##634# installs the Diagnostic app on my phone. But I still haven't figured out how to use the various codes. When the app is running (the screen with the number pad and the "-" showing) I assume that I have to enter one of the diagnostic codes to tweak a setting. For example, I want to edit the HSPDA setting, so I enter *#19732860#, but nothing happens. What should happen, and what might be preventing anything from happening?

Hiyas all, I read through this thread and appreciate all you guys help people like me out. Thanks

Now to the question, I've tried everything you said in the thread about raising dl speeds but im stuck at about 900kbs which i think is pretty low since my Tilt2 got 3.5mbs with the trusty 'H' at the top rather than the 3G symbol.

I LOVE my Focus, had it since launch day. I live in Boston and never not have a 3G signal. So I'm not quite sure what I'm doing wrong.

I've never seen a 3G+ or H on this phone.....

Again, thx guys(and gals) 8)
[Focus General] munkeyphyst:
After turning on the HSUPA, I used testmy.net, my upload speed has indeed shown significant increase. Averaging 80-100 Kbps before turning it on, and ranging 200-850 Kbps after. After several rounds on turning it on and off, soft resetting, etc., those numbers continued to hold true and the increase has shown to be real. As expected, there was no perceptible increase in download speeds. HSUPA is only supposed to effect upload speeds. It clearly has. I cannot report any perceived impact on battery life.

The dual mode enhance thing hasn't shown any perceptible improvements for me, with download speeds or phone reception, but i will try to play more and test further.

This is all on my Focus, and i live in the Chicago area with generally good coverage anyway.

I may try to find a poor reception area and play with turning the dual mode off and on to check for improvements.

Edit: For the record, I am getting 2.5-3.5 Mbps download speeds.

I also just used testmy.net. ran it 5 times. Highest score 161kbs and lowest was 145kbs... download speeds.. i have to have something setup wrong. Any help would be much appreciated. Like i said. I did the diagnosis for connection and for speed with no real gains.

I could never get the root menu code (*#197328640#) to work for me. I have a theory that it's related to the newer firmware revision 2103.10.11.2 or bootloader 4.11.0.9 on my phone.

At some point Samsung changed the firmware and bootloader. See http://xdaforums.com/showthread.php?t=1008191

I have no evidence to support this theory, but I could never get the root menu code to work, nor could/did I ever get a update for the Diagnostics app. I have ver.0929.

the simpler codes like *#2# work. The volume hack *#0002*28346# does not, but the *#0002*28345# does. As I stated earlier in the thread, I was able to use *#32489# and then "back" into the root menu, and do the HSDUPA and dual mode enhanced.
