Cellular & WiFi Performance
The Epic 4G is the second smartphone we’ve reviewed that has a WiMAX radio for use on Sprint’s 4G network. This is actually why I’m reviewing the phone and not Brian, Raleigh, NC happens to be one of the 40 US cities with Sprint WiMAX coverage.
Those of you who read my EVO 4G review will remember that I did’t have the best experience with WiMAX in Raleigh back then. I’m sorry to say that the situation hasn’t really improved much since.
The best download speeds I’ve seen are still in the low 3Mbps range, and upload is usually stuck around 1Mbps while on 4G. On a good day, AT&T’s 3G network is anywhere from 1 - 2Mbps down and 1 - 1.5Mbps up in my area. As with the EVO 4G, Sprint charges a mandatory $10 per month Premium Data fee for 4G support regardless of whether or not you use it.
The other issue is consistency. I usually don’t get those 3/1 numbers, often times I’ll see speeds more like 1/1 or 1/0.5Mbps. I’m always seeing screenshots of users in other WiMAX areas with speeds 2 - 3x my best case in Raleigh, so this may just be a problem with coverage in Raleigh. Either way I’d suggest looking into what to expect in your area before making a decision based on 4G alone.
Speedtest Results for the Epic 4G, all results on 4G except for the topmost result
I will say that I no longer have the problem where 4G performance is worse than Sprint’s 3G in my area. I usually get around 0.5/0.5Mbps on 3G, so there’s a noticeable performance increase when WiMAX is enabled.
And just as was the case with the EVO 4G, 4G isn’t actually more of a battery drain as long as you’re stationary. If you have it enabled while you’re moving around (rather than just turning it on once you’ve gotten to a location) you’ll see a drop in battery life.
Whether or not Sprint itself is a good network for you depends entirely on coverage in your area. In my experience, AT&T is usually either great or absolutely horrible - there’s very little in between. While Sprint (and Verizon) are consistently good. Compared to areas with great AT&T coverage, Sprint can’t compete in performance - but where AT&T’s coverage is weak, Sprint’s average performance is usually better. Awesome occasionally or consistently reliable - those are the two choices it seems.
WiFi performance was better than the Motorola Droid X and the Nexus One, but behind the iPhone 4.
Like all other smartphones we’ve reviewed, the Epic 4G’s cellular signal does attenuate based on how you hold the phone. Given the sheer thickness of the device it’s harder to get the large signal drops by holding the phone that we see on thinner devices.
| Signal Attenuation Comparison in dB - Lower is Better | |||||||
| Cupping Tightly | Holding Naturally | On an Open Palm | |||||
| Samsung Epic 4G | 10.0 | 5.0 | 0.0 | ||||
| Droid X | 15.0 | 5.1 | 4.5 | ||||
| iPhone 4 | 24.6 | 19.8 | 9.2 | ||||
| iPhone 3GS | 14.3 | 1.9 | 0.2 | ||||
| HTC Nexus One | 17.7 | 10.7 | 6.7 | ||||
The biggest drop I noticed was 5 dB when I held the phone normally, and 10 dB when I held it tightly trying to cover as much of the antenna as possible with my hands. This is in line with other Android smartphones (actually a bit better), and obviously better than the iPhone 4.

Hey Dane74,Here's the deal. I've had the phone for three weeks BEFORE it was officially released (I also write for a tech blog). You can look at pictures of SOMEONE else using metric apps, and trying to tally measurements in lab-like conditions, or you can use the phone.
You know what, lets look at Anand's pic. Next to the Nexus 1, it's off by 30m, but has found one additional satellite over the N1. It's only locked to 3 satellites, but is reading better signals from the other satellites it hasn't locked. SO this is probably not a hardware issue (if we're to base EVERYTHING on one pic published by a reviewer that doesn't seem to like this phone that much).
I GeoCache A LOT. Using the GPS in the phone to geocache in really challenging environments to get good satellite line of sight (like the canyons in LA), I'm still within 5 meters. This is comparing the on screen data to map and compass.
Samsung might have issues, but it isn't "Fooling" me. They haven't written any malicious software, they aren't trying to hurt you, they aren't trying to trick you, they aren't evil-ly twiddling their fingers laughing "Muah-ha-ha" style at their customers while petting white cats. They've admitted they have some software issues, and are working on a patch.
My locks do take longer than my EVO, but are CONSIDERABLY faster than my Fascinate (Yes. I have all of these phones.) If the EVO is more accurate, I can't tell when I'm outside or doing turn by turn navigation. Truthfully, for all of the advantages that the Epic offers over any other phone, if it's only accurate to 4 meters and the iphone is accurate to 2 meters, the iphone can STILL shove it. I'm driving/walking/riding a bike NOT engaging in surgical missile strikes...
As to whether or not turning GPS on and off creates problems, I can't say. I haven't had any of these issues. My issues usually stem from not having good line of sight (like when I'm downtown).

Very helpful review... I almost bought one of these. I was hoping with the AMOLED the battery life would be better than the Evo 4G since it actually turns off black pixels from what I hear. Unfortunately that doesn't seem to help. Looks like I'll be keeping my Curve a while longer.michael.gulde - Wednesday, September 8, 2010 - link
Didn't see much about ports on this article does it have a hdmi port?MrMaestro - Wednesday, September 8, 2010 - link
The i9000 (international version), which I assume is the same as the Epic, has a micro-USB port. Samsung has developed a micro-USB to HDMI cable but apparently they took the Galaxy S off its compatibility list on their website, so, I think the answer is essentially no. Still, the cable isn't out yet so we'll see.DigitlDrug - Thursday, September 9, 2010 - link
Hi Anand,Thanks for another great review. I'm curious re. the supposed GPS software fix Samsung is cooking up.
Supposedly the Epic was supposed to ship with this "fix" or had at least been validated.
http://www.engadget.com/2010/08/18/samsung-says-gp...
If you are able to dig up any additional info (maybe prod the engadget boys to see if they're testing methods are as exacting as yours, and what soft. ver they have) can you please update the article or drop in a news blurb?
(I'll admit this is a big one for me, GPS is the one sticking point as I realy heavily on it.)
Thanks,
- J.

The 30m/98.4feet GPS accuracy is a well-known bug. It won't go larger nor smaller. But from my google maps, the accuracy is definitely much better than 30m, probably ~5m. My friends' Epic don't have GPS problem either. You can not rely on the accuracy shown on some test apps.Dane74 - Monday, October 18, 2010 - link
The Epic has such widely GPS problems it is an entire section on Epic GPS issues in the Wikipedia article on it. If you are new to smart-phones, the GPS seems ok, If you know how good GPS has been on smart-phones for the past couple of years, you realize how bad Epic's is. And the picture shows the really low signal, that is the root of the problem on all the Epics.You are new to smart-phones, that is why you think the poor GPS on Epic is ok.

I've had my Epic basically since launch day, and I've noticed (and found others at xda and androidforums) that the phone has issues with both the standard 3g data and general reception.First thing is that for some reason the phone is constantly "without a signal", meaning that for some reason it is constantly searching for a cell signal (GSM?), even in areas with great reception. This can be 'fixed' by toggling airplane mode right after initial boot, and it might even alleviate some of the battery issues since the phone is no longer searching for a signal.
Second big issue is that the 3g upload data seems to be capped at 150 kbps. I have yet to see/hear/read any Epic capable of uploading faster than that on 3g. Even with full bars in the dead of night where I've been able to hit 1700 kbps download, I still get stuck at 145 kbps upload. I know for sure that my Pre before hand could easily hit 400-500 kbps under similar conditions.
Even in the review it looks as if Anand was also hitting the 3g upload wall, but it wasn't as apparent as it appeared to just be a reception issue since the area normally only gets 500 kbps U/D and the down speed at the time of testing only hit 300 kbps.
Anand, is there any way you can test these further?

It's too bad you didn't include the DroidX in the comparison pictures. Hopefully you will when you get the Verizon version.quickbunnie - Monday, September 13, 2010 - link
"I will say that I no longer have the problem where 4G performance is worse than Sprint’s 3G in my area. I usually get around 0.5/0.5Mbps on 3G, so there’s a noticeable performance increase when WiMAX is enabled."Are you sure you are getting 0.5Mbps up on 3g?
There have been no posters with speed tests that get more than about ~150kbps up on any Epic 4G phone, even when side-by-side tests of an Evo will get 700+ kbps.
