No 3G difference here

Tried the tweak but made no difference in my 3G download speed in the Detroit area. Got 116.1kpbs before the tweak and 112.4kpbs after (average of 7 runs on speedtest.net).

Not sure if I can live with this slow of a 3G speed (no 4G available here) since I can't even reliably stream a radio station (something I was able to do on with my HTC EVO). Can anyone confirm if ALL the Epic Touch phones have such poor 3G performance or just some of them. I have 6 more days on the my 14 day period and I'm not sure if I should try to exchange for another Epic Touch, get the Photon, or hold out and hope that it's a software issue and Samsung will actually fix it in a timely manner.
[Samsung Epic 4G Touch] JohnCorleone:
Between my OG Epic and this phone I have only used 3g twice while testing Epic Miui. The 4g adjustments absolutely help me especially when I am sitting on my couch at home and used to get 1 to 2 bars of 4g...now its full bar and connects faster after being idle. I screenie,led out my Epic settings and they were identical.
[Samsung Epic 4G Touch] vdub804:
thanks op now I can do my Clear 4g hotspot hack
[Samsung Epic 4G Touch] monadzback:
The 3g tweaks did not work at all. My speeds were horrible before, averaging about 100kbs up and 250 down, after they were 30/100 with 1000+ ping.

Sprint sucks. So does this phone.
[Samsung Epic 4G Touch] vdub804:
You might need to update your profile
[Samsung Epic 4G Touch] monadzback:
Updated. 255 ping 212 down 62 up. I think sprint in my area is just worthless.
[Samsung Epic 4G Touch] JohnCorleone:
Just love this hack since my OG Epic days. Opinions please....what would best "idle sleep" time be? Been using 120 but thinking of backing it to 60 because wont 300 just use battery when no on 4G for long stretches? It will stay on when you turn off screen. Any feedback is appreciated. Ping is double normal because L.A. server for Speedtest is always saturated
[Samsung Epic 4G Touch] KCRic:
So what's the EntryDelay? It's set at 300, I dropped it to 150 then to 5 and saw no difference in anything.

I'm really wanting to know about these settings. There's a ton of them and it'd be great to figure out what they all are so we can get the most out of WiMax and 3G.
[Samsung Epic 4G Touch] Beejis:
I think (I'm not positive though) it means that it will wait 300 seconds to access the 4g network so making this number smaller will connect you to 4g faster.
[Samsung Epic 4G Touch] JohnCorleone:
I think you are right. The exit delay will be how long before it goes to sleep. That's the one I am trying to find the best balance for
[Samsung Epic 4G Touch] autoprime:
curious on this stuff as well. and what about the options in CT.apk? (##DEBUG## > MSL > WiMAX CT)

all of those text fields populate with info when its opened. some of those settings towards the bottom are interesting... the on/off stuff.
[Samsung Epic 4G Touch] andygallo:
I don't think I ever saw anyone post what all these settings mean, so I did some research over the weekend.

My main questions was what heck CINR was. Well, as far as I can tell, CINR means Carrier-to-Noise Ratio. So I would guess this means, the higher the number, the better quality of the signal.

So knowing that, this is what I think the settings mean:

ScanAttemptTimeout: How long to attempt to connect to 4G (in seconds)

ScanRetries: Number of failed connection attempts to 4G before it gives up entirely (with default settings that would mean about 10 hours).

IdleSleep: When connected, how long to wait for active sessions before putting the 4G radio to sleep (in seconds)

EntyRx: Minimum signal strength allowed for 4G connection

EntryCINR: Minimum signal quality allowed for 4G connection

EntryDelay: How long to wait between 4G reconnect attempts (in seconds).

ExitCINR: Minimum signal quality allowed before disconnecting from 4G

ExitDelay: If EntryRx or ExitCINR go below setting, time to wait before disconnecting from 4G (in seconds).

I only really focused on 3 settings on my phone. Here are the ones I'm using right now.

EntyRx: -00100

* I didn't want this too low, since obviously, if it's too low, the throughput sucks and I'd rather be on 3G

EntryCINR: 00005

* Same reasoning here as the EntryRx

ExitCINR: 00003

* Bumped this up a little. I thought it wise to have it exit sooner if the quality got bad since I reduced EntryRx

Still testing how long my battery will go with 4G on all the time with these settings. Doesn't seem too bad so far.

Please feel free to correct any of the definitions above, again, this is just what I think they mean from my research.
[Samsung Epic 4G Touch] Qortez1:
Is there a way to decrease the time that the phone tries to connect to 3G?

reboot resets wimax tweaks

I've entered these tweaks about five times and everytime i reboot the entries reset.

any suggestions?

Running calkulins rom.
[Samsung Epic 4G Touch] sandhuxda:
On my wife's phone, 4G does not automatically connect after wake-up from standby. It has to be manually reconnected.

Will these fixes apply to remedy this situation?

Thanks.
[Samsung Epic 4G Touch] JohnCorleone:
I have been using these tweaks since around April on my OG Epic. They work great for me. I settled on -100 for minimum signal strength myself. I changed 2 others and everything working great. You should have to have 4g on and reboot after you're done. I made the 4g connect quicker too. They have always stuck through ROM and kernel changes but I have never factory reset before. I always just wipe system/data, cache, and Dalvik when ROM flashing. The factory reset is new to me. If that's in Calk's wipe all zip, it may reset them
[Samsung Epic 4G Touch] bluefire808:
It is hit our miss.some people have great luck. Other don't. Its weird how it only works for some
[Samsung Epic 4G Touch] Beejis:
Not entirely sure it does survive a factory reset but I think it does, but I can confirm it does stick after multiple flashes of different roms and kernels with only wiping cache and dalvik.
[Samsung Epic 4G Touch] JohnCorleone:
Also, a little tip, dialer codes on some custom dialers will not work. It happened to me several times on Epic. So if your ROM has custom dialer and you enter ##data# and nothing happens then that will be why
[Samsung Epic 4G Touch] DataHawg:
I applied these settings shortly after I got my phone. I did a factory reset after that with everything stock and the new settings stuck. I have no reason to believe factory resetting on any ROM will change them back.
[Samsung Epic 4G Touch] Zeroinflux:
Same with me.the Wimax setting stuck even after the full reset to the EG31/EG30-REV5 update.
[Samsung Epic 4G Touch] parkslope:
If you change Swype from English to Spanish it won't change the lower case i to a capital I.
[Samsung Epic 4G Touch] 22350:

Anyone have an idea?
[Samsung Epic 4G Touch] JohnCorleone:
What is your current setup? ROM/kernel?
[Samsung Epic 4G Touch] 22350:
just went back to completely stock. 2.6.65.7-sph-d710.eg30

baseband eg31 "trapped"
[Samsung Epic 4G Touch] JohnCorleone:
Are you trying to change 3g or 4g settings? I know when I changed my WiMax settings I had to be on 4g when I entered ##data#
[Samsung Epic 4G Touch] 22350:
ok, that got it. killed the wifi radio and enabled the 4g. it then allowed me to change

thanks
[Samsung Epic 4G Touch] footfingmaster:
Am I supposed to long press the extensions to change their values? It gives me the option to write extension when i do that. When I simply click on them it doesn't do anything. Running Caulks 2.0 and EG31 modem. Just making sure I don't fubar anything. Thanks.
[Samsung Epic 4G Touch] JohnCorleone:
No problem. Glad you got it to work.
[Samsung Epic 4G Touch] expertzero1:
sweet. 3g tweaks looks like its working now. Testing it before averaging around 150-250 kbps. Now its around 300-700 kbps.

Wimax is ok. But im kinda in the middle of the wimax towers which is lame. I live in a neighborhood with a terrible 4g signal. if i move a mile or so away, my 4g is monstrous!
[Samsung Epic 4G Touch] Beejis:
Sorry I got this so late, but yes you long press the option you want to edit and click write extension. I'll add that to the OP so other folks see this as well.
[Samsung Epic 4G Touch] flexte:
3g tweak made my d\l speed a little faster on average but the upload speeds are a lot faster. will test 4g tweak works a little but doesn't solve my issue. i set the rescan for 15s but after about 10 attempts it stops scanning for 4g. I guess if i am in and out of a 4g area within a minute or so it will reconnect on its own. if not then i have to toggle the 4g switch.
[Samsung Epic 4G Touch] Magicspell:
Wow, I always suspected Sprint data was S L O W

Just got my E4GT last week. No Sprint 4G coverage in my state at all. Decided I'd try the 3G tweaks shown in OP.

Speedtest results pre-tweaks:

Ping: 132ms / 135 ms

Up: 326kbps / 272kbps

Down: 265kbps / 134kbps

Updated Profile and then got these results:

Ping: 147ms / 160ms / 153 ms

Up: 48kbps / 50kbps / 167kbps

Down: 521kbps / 500kbps / 88kbps

Entered 3G tweaks from OP and then get these results:

Ping: 160ms / 132ms

Up: 37kbps / 304kbps

Down: 25kbps / 189kbps

These are all over the place but mostly crappy. Is this just an indication of Sprints poor network around here or should I be looking somewhere else?
[Samsung Epic 4G Touch] Beejis:
The 3G tweaks are really YMMV. It won't hurt anything to try it out and see if it helps, but with Sprints screwy network right now it's really hard to tell. I stick with them personally because I've been doing this ever since this 'trick' came out.
[Samsung Epic 4G Touch] donttrollmebro:
to the OP.. i dont have the phone yet but im wondering about the wimax settings myself.

first thing to try.. ##DATA# but instead of going to edit.. go to view. see if theres a wimax setting in there. it does NOT show up when u pick "edit". if there IS a wimax option under ##DATA# > view.. then it will most likely require your MSL.

another place to try is ##DEBUG# which will require MSL as well. there might be wimax settings somewhere in there.

one last thing i'd like you to try is to install AnyCut from the android market(free). open it and choose to add shortcut or whatever(forget the exact option) and it will give you a list of all the system apks/menus on your phone.. scroll down and see if there are any wimax options. if there are.. could you please list them? could you also make shortcuts for each wimax option you do see and run them to see if you find anything interesting.

please report back with details. you're my eyes on this for now
[Samsung Epic 4G Touch] Beejis:
If you read through the thread we already went over all of this already.

[Samsung Epic 4G Touch] Apk07:
Im on Calks with overstew's ICS theme and I can't access any dialer codes... How can I get to them without flashing back to stock?
[Samsung Epic 4G Touch] autoprime:
id imagine its something with the theme that has altered the dialer causing this issue. if you can remove the theme you should be good.. as long as its completely removed.. or just wipe and reflash calk's rom. i run calks rom stock and can access dialer codes just fine.
[Samsung Epic 4G Touch] Apk07:
Hmm other people with the theme dont seem to have problems. Is there a way to execute this tweak manually? Any terminal commands?
[Samsung Epic 4G Touch] autoprime:
other ppl on the theme have confirmed that their dialer codes are working? most people never notice if they work or not because they never even use them. terminal commands will not work. replace the dialer to stock and all should be good.
[Samsung Epic 4G Touch] JohnCorleone:
Either there's an apk that's frozen or removed or its due to the dialer. Many of the custom dialers I have tryed didn't work. A themed stock dialer should be fine though
[Samsung Epic 4G Touch] autoprime:
for those that cant use the dialer for whatever reason... try out Any Cut from the market.. it will allow you to create shortcuts directly to the data and wimax menus. which ones are which exactly.. thats for you to find out. theres a ton of data options.. try each till you get where you wanna be ;)
[Samsung Epic 4G Touch] DataHawg:
I created the "Extensions" shortcut with Any Cut and that gets you to Wimax settings such as Retries, etc., but can't find the shortcut to change Sprint proxies. Does anyone know how to get to the proxy settings?
[Samsung Epic 4G Touch] chandlerw88:
Bump. Can we get this stickied mod?
[Samsung Epic 4G Touch] Beejis:
The Sprint 3g fix is in the op at the bottom. Go to your dialer, type ##3282# click edit then type your in your msl. Click others, them click multimedia. Enter the given entries from the op.

not working on my device

I've tested this tweak a couple of times but speed test shows it's getting worst.

1. First of all, I've applied the setting "full wimax settings" based on http://xdaforums.com/showthread.php?t=1447615

After applied this setting my 4g speed increased incredibly.

2. Upon my current settings, I've applied this tweak but the speed went back to my original speed before applying "full wimax settings".

The procedure I tested this tweak on my system is,

a. applied tweak for 4g and 3g

b. rebooted system

c. Tested speed using "Speed Test"

d. moved back to original configuration and rebooted system again

e.Speed test

The below snapshot is the result of my testing. This test would be applicable to my device only because mine is not the original stock rom. Mine is Calkulins.E4GT.ROM.v2.8.
[Samsung Epic 4G Touch] AndroiDemon:
Apk, this is because you're not using the stock dialer... You're likely using touchpal or similar.

Open your app drawer and locate "Phone" in the list and use that to dial these codes in. As soon as you hit the last pound sign, the utility will come up. If it doesn't, you're not using the stock dialer.

Thats not true..

You just need to back-door it by usng anycut, nova activities, or apex activities to "WiMAX Hidden Menu/Extensions" on ANY phone with WiMAX.

While youre at it, make a shortcut to "wimax mode change"...

That guy with the speed tests up there told me about them.... They are ridiculous. Dm mode and SDIO are fantastic! Thanks!
[Samsung Epic 4G Touch] Beejis:
As long as you don't mind, I'll update the OP with these suggestions so other users can try it as well if they use those roms. Not entirely sure if they do work but it doesn't hurt to try.
[Samsung Epic 4G Touch] Raistlin1:
Used these tweaks and now when I lose Wimax and then go back to a location that I know there is service Wimax won't reconnect.

The 4G icon is there an greyed out now instead of showing zzzz when I lose signal but it would always turn back on when I got into a service location.
[Samsung Epic 4G Touch] kdelinux:
does this apply if I am running FE22 modem and kernel? on 4.0.4?... it should like the hack would allow me to access the setting after a year being posted. but does the hack still work for the speed?

It will if it's a TW based rom for sure. AOSP/AOKP it will apparently too.

Does anyone happen to know why my 4G freezes sometimes? I am sitting at my desk, where I have 4G, and instead of showing zzz it greys out like I am not in a 4G location and then my 3G is on.

I have to reboot to get 4G to work again. I only noticed this happening after the did the tweaks listed in this thread. So I went back in an raised some of the values, not back to default but in between, so maybe that will help or this is a completely unrelated issue.

Thanks
[Samsung Epic 4G Touch] autoprime:
in all tests that i've done... editing wimax mode changes nothing. run a wimax test 20 times.. and 15 out of 20 times the speed will be completely different. i chalk up any "benefits" to this effect.

3G settings?

I'm currently using Usual Suspects (CM9) so the dialer codes don't work. I'm instead using AnyCut and have already modified by 4G settings. However, I've been looking for the 3G settings (the ones under Other -> Multimedia) and I haven't had any luck finding them. There's no Multimedia option or even a DATA option.

Any thoughts?
[Samsung Epic 4G Touch] Lonbobby:
I used this on stock and it worked great but I just rooted and installed CM10 and I don't understand what anycut, nova activities, or apex activities are. I know nova and apex are launchers. Is there a setting within the launcher? Any help would be appreciated.
[Samsung Epic 4G Touch] Omar04:
3G Tweaks doesn't make any difference at all. I've been doing that for a long time and never has made any difference, at contrary without any change I got more stable speeds.

[Samsung Epic 4G Touch] zedomax:
I've tried a hundred different settings, tweaking Samsung's original c1_rev05_na_spr_defconfig file.

c1_rev05_na_spr_defconfig is the .config file given by Samsung in the open source code for those of you who don't know.

When you can correctly compile the kernel with the settings in this .config file, you should be able to end up with a stock zImage that works but right now, these kernels end up in a boot-loop or boot-freeze.

I suspect it's settings in the .config file (off the c1_rev05_na_spr_defconfig) that could be at fault. I am not an expert at this (by any means) but perhaps those of you who are can recommend me any changes to the settings.

There's also an older c1_rev02_na_spr_defconfig but it doesn't compile so...
[Samsung Epic 4G Touch] shabbypenguin:
as ive stated in other threads, you wanna double check your kernels use tools to unpack the zimage.. if you dont have the initramfs in there then its not gunna boot
