I got 1400kpbs down and 148kps up on I95 in south florida, 4-5 bars. bars don't seem to make that much difference. I've seen 1000kpbs down on 3 bars. but upload is always stuck.
[Epic 4G General] thephawx:
Hey guys, please call up Sprint and/or head over to a Sprint store to let them know that there is a problem with 3G upload speeds.

Or contact @samsungtweets and @sprint on twitter with the 3g upload speed problem.

The more people that see that has the problem the faster they can go to push out an update.
[Epic 4G General] k0nane:
I've seen this, not a major city. 1.1mbit/150kbit typical.
[Epic 4G General] robl45:
i emailed chris@engadget.com he did the review on the epic. I think we'd have far better results if endgadget or someone picked it up. sprint has waaaay too much incentive to let it die quietly.
[Epic 4G General] hydralisk:
Posted this on another forum... but may as well post it here as well. I actually went into a Sprint store today to have them look at it up close. I came out of that store ****ING IRATE.

Well first of all, the customer service guy was nice as always. He was actually shocked when I showed him my download speeds of 1500 Kbits, but only 150 Kbits upload max. He said that isn't normal for the Epic. He changed the server a few times on the speed test app... same result. He said the Epic should be faster and to take it to the tech guys.

So I waited in line for about 20 minutes. There were a lot of people with issues related to their blackberries (hah). Anyways, they finally got to me and I showed them my upload speeds. They said that's probably normal for the phone. When I asked him if it sounds normal that a brand new $500 phone has a slower upload speed than a 2G phone, he said "but that's a 4G phone." When I asked if it's okay that I'm paying $10 more a month for a REALLY POORLY capped upload speed, he said I'm paying $10 a month more for 4G... even though I don't even have 4G at my house.

He then plugged the phone into some diagnostic tool that also can tell what the actual download\upload speeds of the phone are. He said 150 is average 3G upload for this phone and there isn't anything they can do about it. It is what it is. Samsung HAS to fix it... or it wont get changed. He didn't seem like he cared at all though. He talked down to me as if I was a spoiled brat.

I dunno... as much as I don't care about my 3G upload.... this is ******ed. I wanted to return my phone right then and there but the idea of going back to my EVO depressed me... so I'm going to stick it out and see if this issue is brought to Samsung's attention.
[Epic 4G General] 1999TL:
This is pretty wack. I hope a solution comes out soon.
[Epic 4G General] Firon:
We should probably all complain to Sprint. The more people complain, the more likely they will actually fix it.
[Epic 4G General] ElT0R0:
Given that the Fascinate is not having the same uploading issues, would it be possible to flash the Fascinate radio onto the Epic? Would that even solve the problem? I guess I'm not too familiar with radio flashing and compatibility.
[Epic 4G General] p2flol:
Yeah.. I've already emailed them and spoke to them on the phone, not very helpful.. have to wait for samsung is what they told me :\
[Epic 4G General] 1999TL:
lol I'm getting 1500 download and 145 upload. LMAO.
[Epic 4G General] rufflez2010:
Got you beat there! I was getting almost 3 down earlier.
[Epic 4G General] 1999TL:
We both LOSE...lol

[Epic 4G General] robl45:
I got nice upload speeds last night for 2 minutes. between 400-600 and now back down to actually worse speeds than previously.
[Epic 4G General] hydralisk:
Jesus, that is pretty impressive 3G compared to what I get. My BEST has been 1.5 down. I didn't realize 3G could go that high.
[Epic 4G General] rufflez2010:
Yeah, surprisingly, that was at work. Its an older building and penetration is good. When I work at newer stores, my signal is usually pretty low and speeds are pretty bad. The lady at the Sprint store said that city I was in was supposed to get 4G "soon", but I would imagine there would be a lot more cities in Florida to get it before Melbourne. Considering how poor the coverage in Ft. Lauderdale is right now, they need to do some work down south before they should be coming up here. And the Island I live on, please, might be done with the 2 year upgrade before 4G comes... but, I do live by a 3G tower, so speeds are still good at home.
[Epic 4G General] jaygraffix:
Just to add to the list..

In Milwaukee, WI

I'm getting slow upload speeds as well, barely breaks 150 kbps. If I do the tests over and over again I seen it as high as 170 but that is very rare.
[Epic 4G General] nitroxeno:
Can everyone having this issue please try and use Dialer Code: *#4636*1111# and then Select Phone Info. This will report your current data status of 1xRTT, EVDO rev. 0, or EVDO rev. A.
[Epic 4G General] rufflez2010:
Rev.A, not that I doubted that with my download speeds.
[Epic 4G General] drjonesok:
I've never hit over 150kpb/s upload on 3G and I've even swapped a phone for this issue. I live in OKC.

The 3G upload on my HTC Hero was a lot faster. Sounds like a cap to me. How can they charge us an extra $10 a month when they capped our upload. We can't even use qik or another other video conferencing software over 3g. My Hero was able to handle video upload decent and it's not even made for that stuff. Class action lawsuit anyone?
[Epic 4G General] ElT0R0:
CDMA EVDO rev. A
[Epic 4G General] liamaa:
I have an evo and my friend just got an epic. We were doing side-by side tests in manhattan. Our downstreams were generally fairly comparable at about 800kbps-1.2mbps. But I was routinely getting 500-800kbps up on my evo while he never broke 200 on his epic.
[Epic 4G General] volcomjerk:
Everyone please call in about this issue. I called in and I was the FIRST to do so. Nothing is gonna happen whining on XDA.
[Epic 4G General] thephawx:
That's BS. I called in last week and the customer service rep was no help at all. He was saying that I was getting a higher upload than I should be getting so it's not a problem.

So I walked over to the Sprint store near my office and I also talked with the tech guy. He thought I wanted to swap out my phone, I told him ALL epics are like this and a report needs to be filed so that we can get this fixed.

I seriously doubt this is a hardware problem on the modem and it's more likely a driver issue with the modem. And it's not a system wide cap because 4G easily breaks past 1mb when I am in 4G coverage.
[Epic 4G General] nitroxeno:
I think at this point everyone needs to post on the offical sprint thread here: hxxp://community.sprint.com/baw/thread/43883?tstart=0

And then after you post call sprint and refer them to the that topic on their own site so we can get some real attention on this issue. According to one of the sprint admins he is not even showing this as an issue on their internal systems yet... lets change that!
[Epic 4G General] robl45:
i can prove its not a hardware issue, I posted the screen shot on android forums, for 2 miinutes I had great upload speeds.
[Epic 4G General] epv:
i don't think it's the radio firmware. the cap appears to depend on what type of IP traffic you're sending. mine also shows 150kbps up with the various "speedtest" apps, either local to the phone or tethered, but when running through a vpn it gets closer to 600 or 700kbps up, either local or tethered. The speedtest apps seem to use port 80 for the whole test, so possibly it's just rate limiting tcp port 80 traffic, which would make it very much a deliberate policy decision and not an accident. :)

Makes it additionally weird that they don't ratelimit 4g, and that the still charge you an extra $10/mo tax for getting lower bandwidth than you'd get with other phones they sell. Very weird.
[Epic 4G General] thephawx:
Does Qik use port 80?
[Epic 4G General] autoprime:
i have both the evo and the epic. i have both phones cloned to a htc diamond. same ip set to all 3 phones. same everything really.. and only my epic has the limited upload. i had noticed this the very first day the phone came out and assumed it to be a software issue with 3g. glad i came across this thread.. so now i know im not crazy.

i get great upload with wifi and 4g on the epic.

if traffic is limited on port 80.. its done thru the software on the epic itself.. as sprint has no idea my phone is an epic 4g.
[Epic 4G General] navoid:
1.7 down and like 70kbit/s up. Sad upload.
[Epic 4G General] nicknomo:
Its not just port 80, I ftp at 18 KB/s (140-150 kbps).
[Epic 4G General] aero1:
It is good advice but you were not the first to call in. I called in about it last week, and I was told no one had ever called in on it, and from forcing an escalation I am near dead certain they have known about this for some time and that peopel have been calling in with this issue since day one or two.

I called the device team (top support) contact I had spoken to about the GPS issue and they knew about this issue. So what you are observing with "first to call in" is simply that even second and third their support will just say this to you on anything. You could say "this Epic phone has Android" and they will say to you: "NO, I never heard of that, please reset your phone."

If you call in today and ask first or second tier support if their are any GPS issues they will say there are none. Device Team has GPS on their list along with Data speed and certainly since last week.

But I would not underestimate the possibility this throttling is intentional and that there maybe a disagreement between different departments within sprint.

I think an even bigger scandal is that the major reviewers did not find or note this. BoyGenious, Gizmodo, Engadget, TreoCentral, CNet all had gushing "in-depth" reviews and they did not run even a simple 10 second test of 3G?
[Epic 4G General] 1999TL:
I agree. One of the review sites should have noted it.
[Epic 4G General] arashed31:
I used to own a Samsung Moment which has the same modem as the Epic.

It wasn't until the Android 2.1 update that we got upload speeds higher than 150kbps. After that I could get uploads faster than my downloads ~600kbps.

I'm pretty sure Samsung doesn't know **** about the QSC6085. Someone PLEASE rewrite the drivers for this phone. It's horrifying to see other phones with the same Modem processor (Droid/X/2) that have much better performance.
[Epic 4G General] javahead76:
I've received my OTA Update. My download speeds pretty much doubled immediately. Before, I was getting 800kbs downloads. I got that speed every single time I tested. My first test out with the September 16 system update got me 1775kbps down. Still only 153 kbps up. Looks like it fixed my (what I believe to be throttled) downloads, but not my uploads. I guess they've no intention of changing that at this time (or can't depending on the hardware in this thing).
[Epic 4G General] compuw22c:
I also noticed yesterday that while listening to music, this amazing cpu was horribly bogged down and began stuttering (mp3 on sd card) when all I did was attach a 1.6mb picture to an e-mail and send it. HUGE cpu usage apparently. In phone throttling is my guess. I looked at a few of the network config files but didn't see anything that looked out of the ordinary...
[Epic 4G General] J3ff:
Whenever I upload anything it studders like crazy!!
[Epic 4G General] drizek:
Same experience here. I never thought that these two things were related, but it seems like they are.
[Epic 4G General] Muckrak3r:
In the DFW area today, in a parking lot. I tested using the speedtest.net app.

4g - 2.58 down / 741k up

3g - 1.45 down / 158k up

No matter when/where I test when on 3G, the upload is definitely capped. My buddy with the iPhone4 got 1.37mbps down and 1.22mbps up on 3G.

We pay $10/month more for "4G" and his 3G upload is more than both of my tests combined!!! hahaha
[Epic 4G General] jfenton57:
It Isn't Just an Upload Issue IMHO

Just got home to Haverhill, MA and ran tests again with 4 bars showing.

Speedest showed 260 Kbps DL and 100 Kbps UL

I then ran it with the BroadbandDSLreports browser based test and got 264 DL and 112 UL.

Just for the heck of it I then tested with my wife’s BB Tour which I gave her when I got the EPIC and got 1870 DL and 760 UL

I for a moment don’t believe that this is simply an UL issue and it’s a sin that the EPIC is way below what a BB is doing.
[Epic 4G General] greengoldmello:
Man, im getting the epic tomorrow (my 4th smartphone this year) and the comments on this forum are already letting me know i need to keep my packaging when it comes in..for when i want to send it back..from the horrid battery life when using 4g and gps to capped 3g upload speeds..sounds quite buggy and i wish sammy would give some feedback to some of the problems. I also remember noting that my vibrant stuttered a couple times while playing music, but on the slightly weaker Nexus I had before it NEVER stuttered my music while browsing the web. The only phone i can remember that I had that did that was the n900 with a freaking 600mhz processor..so it was kinda acceptable then..but now..no..wtf
[Epic 4G General] compuw22c:
More useful info that may explain our issue:

A quote from noobnl on cyanogen forums:

"i have alot of experience on samsung android devices.. don't believe me? look me up on google..

i did the first step on porting cyanogenmod to the epic :)

i did the vendor files: http://github.com/no...ce_samsung_epic

it will be hard to port the RIL because the RIL is a gsm wrapper in CDMA hardware "

http://forum.cyanogenmod.com/topic/6684-cyanogen-mod-6-port-to-the-epic-4g/

Could this explain it all? The fact that our amazingly fast, overpowered processor sucks as a PHONE because its essentially EMULATING the entire radio? It certainly would explain a lot, why the 3g takes so much power, etc. Because not only does it need to power the radio, but also run the cpu (possibly as high as 100%) to do all the legwork that SHOULD be done by the radio hardware?

Noobnl, help us!

Also, can anyone using an overclocked phone/kernel comment on the issue? If this IS in fact the issue, then overclocking SHOULD raise the upload speeds to say... 170-200kbps. Still pathetic don't get me wrong, but it would indicate where the issue lies...
[Epic 4G General] jfenton57:
Just ran this from home with several different servers...
[Epic 4G General] aero1:
Irony: Actually sprint has regularly insisted you don't pay the $10 for 4G as the charge is for all areas of the coutnry. you pay it, insists Sprint, because of you get more 3G utility. So the $30 Sero customer with say a two-year-old WM phone is the "parasite" customer, and you are the premium customer with the shiny new $500 top dog handset and a $60 a month plan, and you get 1/3 the speed. a:eek:
[Epic 4G General] usfslacker:
Wow...

I'm looking to upgrade from my HTC Hero on the 1st of October and I really want the Epic. I love the keyboard, love the media software (is there a way to get Evo to play AVI/MKV videos?), love the screen, but between this, a purported radio bug that makes it destroy the phone's battery and a defective GPS, I just don't know if I'm going to be able to sway away from the Evo. The extra $50 doesn't help either.

For reference sake, I just ran a Speedtest on my Hero (North Tampa, 2 bars of signal or 88dbm) and got 780kbps down and 680kbps up. I hope they get this stuff straightened out, as I genuinely prefer the Epic.
[Epic 4G General] rufflez2010:
mPlayer in the market will allow for both mkv and avi playback.
[Epic 4G General] crawrj:
I have had the same problem since getting the Epic. Mine would go so far as to not allow me to do anything until the transfer was complete. I tested this first thing after the update and could not get it to lock up. So it appears to have been fixed with the update.
[Epic 4G General] Xerloq:
My wife's Moment got 466 kbps up with 3 bars. My Epic got 148 kbps up with 4 bars. The phones were next to each other while testing.
[Epic 4G General] jasonsf:
Just tested my Epic next to a friend's Evo and he got 600+ kbps next to my 148 kbps up. Not to mention his dl speed was twice mine.
[Epic 4G General] NightSidew1nd3r:
I got 1500kbps up and 4950kbps down on 3g on xperia x10, on Telstra network in Australia
[Epic 4G General] Muckrak3r:
I hope everyone is reporting this issue. Speaking of, what is the best way to report it? Can we report it to Sprint and Samsung?

I will report it, and follow up, and follow up. It's straight up embarrassing seeing my friends with iPhones get literally 10 times faster UL speeds, and 5-7 times faster DL speeds. Simply not the way this should be.
[Epic 4G General] J3ff:
Anyone have a better way then just calling some random tech ?

Maybe we should mass email Dan@sprint.com

, I just emailed him, maybe if we flood his box with REAL complaints about it - someone might take a look
[Epic 4G General] mrv8killer:
I just got 75 upload and 96 download on 2 bars of 3g my g1 was faster than this. I hope it gets fixed soon.
[Epic 4G General] APOLAUF:
Sounds like you were sitting on 1xRTT. The "3G" indicator is completely misleading. Instead of showing "1x" when it should be, it doesn't. Evo had this problem. The speeds you're getting are definitely commensurate with 1xRTT, not Ev-DO (3G).
[Epic 4G General] mrv8killer:
Wtf this is a 1st time seeing this got it twice.
[Epic 4G General] bitbang3r:
Actually, the bottleneck is probably the microSD card. The interface between (micro)SD and the CPU is slow. Dog-ass slow. You can only access the data 1 or 4 bits at a time, via a protocol that has a comparatively huge amount of overhead for anything besides sequential block transfers. And in many cases, you can't use DMA to do it. In a very real sense, microSD truly is the successor to the floppy disc. Imagine trying to simultaneously stream .mp3 from a floppy disc while sending a .jpeg from the same disc (pretend it's a 2.88mb disc). The reality isn't much different.

Reading data from (micro)SD is like trying to suck a milkshake through a cocktail straw. Or 4, if you're lucky. By comparison, reading data from SRAM is like inhaling water through 32 or 64 large-diameter McDonald's straws at once. In fact, that's a great analogy, because the "how do you fit your mouth around 32 straws at once" problem kind of shows that you end up with new problems to deal with that prevent it from being 100% ideal, but still infinitely faster than the alternative.

Phones like the Vibrant and Captivate just make matters worse by using a second internal microSD card for just about everything. Go to their forums and read all about the huge performance difference between the 16gb internal card and the much, much faster ~168mb of "fast" flash.

MicroSD is a lot cheaper than alternative forms of flash for a reason... it has a simpler, slower interface. If you're using it for reading and writing sequential chunks of data by basically one task at a time, it usually works OK. The moment you try treating it like a solid-state hard drive, its performance collapses because it's just not suitable for that task. You can make matters a little bit better by using performance-optimized class 6+ microSD flash, but even the fastest class 10 microSD flash with overclocked controller is going to suck miserably compared to just about any alternative.

In fact, that's the reason why nearly every smartphone has started out with a restriction against having ringtones and apps run from (micro)SD. The programmers and engineers just took for granted that nobody would ever want to do it, because the performance sucks so badly. Then normal consumers get a hold of the device, and scream because they can't take advantage of the extra capacity.
[Epic 4G General] rockethot:
Here's mine going over 150
[Epic 4G General] hydralisk:
The cap is still present there. It's clear that the upload TRIES to get over 150 and sometimes it does just by a little bit, hence the 174... but when your download is that high, the upload speed should be close. I'd say around 600-700.
[Epic 4G General] rockethot:
Here's one of my results from last night, going well over 150
[Epic 4G General] jfenton57:
Doesn't anyone see a problem with DL speeds being lower than UL Speeds?

There is definitely something amiss and personally I think the DL speeds suck as well.
[Epic 4G General] hydralisk:
For me they don't suck. I get almost the same max DL speeds for both my Epic and EVO. The problem is.... the connection on the Epic is shoddy at beast. It's a LOT more jumpy in the speed test apps. It will go up... stutter... then drop way down and start climbing back up. This causes the speed to seem lower. The EVO is rock solid in its connection and the speed test apps runs much smoother... but the max speed is similar for both devices.

The reason the upload will sometimes seem higher than download is just timing. The DL portion of the test could have been running when the 3G connection was weaker. It is VERY jumpy.....

I hope this gets fixed before anything else because I use 3G internet more than I use GPS and 4G...
[Epic 4G General] mrv8killer:
Finally got a good speed
[Epic 4G General] Dameon87:
I get more than 150... soon as I figure out how to upload... lol.
[Epic 4G General] Dameon87:
Another ss. should Be more clear.
[Epic 4G General] APOLAUF:
Those of you able to get faster than 150kbit/s uploads, when did you get your phone, and might your serial number say anything about this? Or is it exclusively per location?
[Epic 4G General] robl45:
how many times does this need to be said, it has nothing to do with serial numbers, its not hardware related, I've done it on two different epics, randomlly I'll get normal uploads. does that sound like a hardware thing? I don't care what anyone says, i'm almost positive it has to do with the sprint network and i really think its related to the gps bug in the phone.

When I got over 150 (I'm back to the cap, not that I care much), I was in an unusual place, driving on sr528 in orlando. With no house for miles, I was getting both insane dl and ul on this phone before making it to 4g land in orlando. I also had the update pushed to my phone at that time, too.
