to get a better idea, we should run the speed test 3 times (take the average) at a few different points during the day (morning, afternoon, evening, night?) in the same place, then take the overall average... this will give you a more accurate whole picture.
might be a good idea to put where you live in there as well.
using the above method (3 simultaneous tests, 1 morning, 1 afternoon, 1 evening, 1 night), my results are as follows... both radios were tested in the same location at the approximate same times a week apart. I'm in eastside seattle:
26.02.01.15:
DOWN: ~4.8mbps
UP: ~3.5mbps
26.06.04.27 (w/ updated lib files):
DOWN: ~5.4mbps
UP: ~3.9mbps
noticeable (not just placebo effect) decrease in browser loading times and GPS is much better for me. switching from towers seems to be quicker as well - my phone used to hang for 10-15 secs going from 3G to H, now it's almost instant even in the middle of communication. have been extremely happy with 26.06.02.27 so far... I may try some other radios just for testing, but I'm scared to screw up what is already a pretty solid setup.

You should also note that just because your phone has the "H" icon in the status bar, doesn't mean that you're on the "4G" network (which technically is HSPA+). The H can refer to HSUPA (instead of HSPA+), and it will often stay on H even when you're down on UMTS (3G). I don't even have HSPA+ "4G" in my area, being told that its on the way in the coming months, and H is lit up all the time, but its just HSUPA.
Something to think about.
That being said, I generally get about 1.9mbps down, 1.9mbps up on HSUPA. Stock radio.

I average between 4.5mb up to 8mb depending on data traffic and my uploads average around 2.5mb
I think most of it just has to do w/ the coverage in your particular area.

I get the "H" icon a lot at home, but my speeds are usually < 1 mb as you can see:

The most recent amazingly fast ones are taken at my work.

I'm getting an average of 4.2 Mbps using the stock radio.
Can you change the radio when you're not rooted? Don't really know much about radios.

Network speeds are affected by much more than simply your radio version or ROM type. See my post above for explanation of the "H" icon in your taskbar for a little look into that.
You can flash your radio independent of your ROM, some people get better performance with other radios, but I've gotten consistent performance with my stock radio and a few different ROMs.

Yes, you must be rooted to flash new radios. Unless you're having network issues, and you're happy with your speeds (I hope you are at avg 4.2mbps) then there's no need to be flashing different radios.

Running virtuous v1.0.1
I only get 350kbs-1.5mbs download and 800kbs-1.5mbs up. The upload isn't the problem. The best download I have ever gotten was 2.2mbs in my area (with the H or 3G+ symbol and 3-4 bars). I did get 3.5mbs download once, but that was on the other side of town.

Just to clarify, when I said 4.2 mbs was my average, I meant my average at the moment. I did 3 tests.
Although, my average overall is usually about 2.5-3 mbs which is still good enough for me. Just hate when I randomly get Edge out of nowhere.
Best speed I ever recorded was 5.37mbs late in the afternoon a month ago or so.

Man I thought I lived in a **** town because I only saw 6.5mbps max when our phones are capable of easy double digits. Especially when I see some people having screenies showing cell speeds of like 9 or 13mbps. I guess I have nothing to ***** about.
Although I have found I can do just about anything I really need my phone to do if I have atleast 1.5.

I only get like 5mbps downloaded and 2mbps uploaded. I really dont think that the 4g network isnt completely up yet but the speeds are okay with me.

Question regarding different roms and cell reception

I have been running chingy's re-engineered and the rom rocks as well as cell reception! I went to cm7 to see what it's like and cell reception is horrible. I also tried redemption rom and noticed cell reception was horrible as well. I am back to re-engineered and 3g is consistently connected with anywhere from 3-5 5 bars, but when I was using the other roms mentioned I would see weak 3g signal and occasionaly switch to 1X. I tried searching and couldn't find anything on this issue. Anyone have any ideas?
I have also read that the issue is a cosmetic thing which I can understand. But when it switches to 1x, that in my eyes is an issue. But its strange that this only happens with incredible roms built from source and not with evo roms.

Chingy's ROM using the EVO's 6bar signal strength meter, but CM7 and most stock ROMs only use a 4bar signal meter. This is why you see a perceived difference, but honestly I've never noticed a performance increase or decrease for that matter when I switch betweens ROMs regardless of what my status bar says.

Thats what my thinking was. But, I see full strength with chingys but actually switch to 1x from time to time on cm7, which is the wierd thing.

i dont know if signal is worse, but i think they handle the lack of signal differently.
I am using myn's and when there is no signal and you try to make a call it fails immediately with no error at all whereas with the stock rom it would say call failed.

Different ROM's measure the reception differently, if you go into settings > about phone > Network -- you'll see the dBm measurement of your signal.
This jumps around a fair amount too, so take that into account. It will vary depending on where you're positioned in your building / house, the weather outside, etc.
Your signal should be exactly the same from ROM to ROM, flashing a new Radio is pretty much the only thing that will change that, and those aren't included in ROM's.

Sounds good! Currently running Miui which is great, and haven't lost 3g yet so maybe the past flashes were just flukes.

Slow 3g speeds

Lately I have been experiencing some slow 3g speeds. At first I thought that 3g reception in my area was just not very fast, however I don't think that's the case anymore. For example, I did a speedtest and got 300kbps down and 400kbps up while a friend of mine standing right beside me (also on verizon and has a Droid X) got 1000kbps down and 500kbps up.
What could be causing slower 3g speeds? Any help would be great as slow speeds are very annoying. Also now he keeps insisting that his phone is vastly superior to the Dinc...

Also, throw our massive dev community in his face if he thinks his phone is all that. Locked bootloader < Inc.

I have not tried flashing a new radio ever sense I first flashed 2.15.00.07.28. Is there another radio I should use or could reflashing that one help at all?

Noooo no no no no don't flash the radio again. That causes bricks, so I've heard. There are three newer radios than yours (9.01, 11.19, and 4.09, in that order), but there isn't any way to tell which one will work for your phone in your area except by trying them yourselves. But... Flashing radios is risky. You should always check your MD5 sum with the one provided from where you downloaded it. You can get them all from www.dougpiston.com
Sent from my Droid Incredible running CM7.0.3.

Only way to brick is to pull the battery when flashing the radio. Check md5, have a good charge and you'll be fine.

Ok if a new radio might help I guess ill try that.
The same friend mentioned that his rom included something that removed the data throttle. Obviously that could increase speeds... anything like that for the Dinc?

I don't know if it was just the natural variation in data speed but I got better speedtest results with the 4.08 radio. As far as throttling, if there is any throttling done its on Verizon's side and you can't do anything to your phone for it. If you were being throttled you would see an icon in your status bar and (should) receive notice from Verizon. The only people that would be throttled are (I think) the top 5% of data users so unless you use A LOT of data I wouldn't worry about it.

Cyanogenmod 10 Stable AT&T Galaxy S3 Connection

Hello, I I'm using the stable version that was just released and my phone keeps switching from H, H+, to 3G every 20 seconds or so?! What am I missing here? I have flashed all of the AT&T modems and the problem still exists and drains my better! I cleared everything before installing and everything else is working fine! Just not the data connection. Please help!

Sounds like a problem with AT&T. Some quick things to try when your connection is wonky like that is to toggle airplane mode on and off. I'm in Canada, so I'm not entirely familiar with AT&T, but I have read on a few other posts that they are a little sketchy right now as they roll out LTE to more areas. Also try running with just 3g for a bit, then try LTE and see if anything changes.

Tried doing that Still having issues.
I don't have LTE in my area, so that's not the issue. I do have the HSPDA+, so I get why I see the H+.
It seems to only be with the Cyanogenmod 10 Stable ROM that was just released 2 days ago. Doesn't seem very stable to me
I even just tried installing the nightly update that came out last night to see if there was a fix, and nothing.

Hmm, okay, well, then if it was me in your shoes, what I would try would be flashing back to stock with Odin and start over from scratch again. I find that's easier than messing around with radios and modems and everything. You can find a good stock image in the android development thread that already has root injected into it. Obviously make sure you grab the right image, yadda yadda, yadda.

If you're saying that its switching between 3G, H, and H+ in succession then its doing exactly what it should be doing. Think about it. If your devices data was constantly stuck on the highest speed (the most battery draining one) your phones battery life would be horrible. What aosp based ROMs do is show the true value of your data connection. What's happening is your device is switching to the lower level data (3G) when you're not using data services and then ramping up to the higher level (H+) when you're using data services. Touchwhiz based ROMs don't do this. They lie and always show the highest level data as always being used when in fact the data levels are actually switching back and forth like you're seeing right now.

Thanks, dude. I looked at it as a problem that needed fixing - but I guess if that's what it's supposed to be doing then it's not a problem at all. For some reason, I never see my data type drop from 4G.

If you're in an area with a really strong 4g signal it will stay on 4g. I've noticed that at work it stays on 4g the whole time but at home where my 4g isn't as strong it will switch back and forth.

Are you ABSOLUTELY certain about this? I will just let my phone sit there (not doing anything) and the icons go 3G, H, H+, back down to H in literally 3 seconds.
This doesn't seem right. Especially with my battery draining about 20% in a matter of 20 minutes. I figured it was because the data connection was jumping all around.
Can everyone else confirm that their phone is doing this too (jumping between all sorts of connections) that is running Cyanogenmod 10 Stable?
Oh, and I'm in a really strong "4G" area downtown Minneapolis, etc.

not sure why you would think that i would give information like this without knowing. either way. thats how its supposed to be. its flipping back and forth like that when you're not doing anything because of email syncing and things like that in the background. whether you think youre in a "strong 4g" area or not. your device knows better than you. if its switching in an area the you think its strong in, it's probably not as strong as you think if your device is saying otherwise.

Alright, thanks for the explanation. I might try it one more time tonight, but on the way to work today the data connection was flipping back and forth constantly, draining my battery as well too. I've been around the Twin Cities today (not just sitting in just 1 spot) and still happens. So I doubt the entire cities is not as strong 4G as I think :fingers-crossed:
Keep you posted.

WIFI Issues
Hi All:
I'm not sure if this the same issue as whats listed here but on CM10.0.0 Stable, wifi seems to fail to reconnect after the phone goes into sleep mode. In stock ROM, I could bring up the wifi menu by dialing *#0011# however on CM10 it doesnt work.
I know others have listed this issue on the web (not just xda) but wondering if any one has a fix? Thanks.

Okay, I'll admit when I'm wrong. Had some patience tonight and my mind wasn't playing tricks on me now that I got an explanation. Battery life is fine, and Internet connection doesn't go out when I'm on the browser ^_^
Thanks for your explanation!

hey...i know this might be a bit late but I'm on a rogers sg3 running CM10 stable as well and i mine is doing the same thing. I can understand where you are coming from because it seems that mine started doing this after i lost IMEI and restored. i think it's purely a case of me noticing things a little bit more after that whole ordeal. can't really confirm if it was doing this before but it seems to be working fine right now. recently i was in a very strong 4G(LTE) area and phone didn't switch at all...just stayed on LTE constant. At home on the other hand(rural ontario) my phone jumps around like crazy. I've even seen it go right down to E lol! So I, like yourself was a little skeptical and decided to switch back to stock and sure enought it just stayed right on H+ makiing me think that i was getting "better" service on a stock rom lol. but when i went into phone settings/about phone/status the mobile network type kept swiching even though it showed H+.
anyway...just my 2 cents. hope this puts your mind at ease

AOKP vs TW signal reporting

I have been trying to figure this one out for ages!!!
Can anyone answer why TW roms report signal strength different from AOKP. (I don't mean 4G vs LTE or faster or slower speeds) When I have a TW rom installed, I can go virtually all day and have no reported signal loss, but if I have a AOKP (all source android for that matter) installed and I use the phone in the exact same place I have as much as 50% time without signal while the whole time I actually have signal as I use the phone. On the TW rom, signal almost never goes less than one bar but yet I can have no signal at all, but if it is like that for any amount of time then it will show no signal, but the AOKP will show no bars but still have signal and yet it still reports as no signal.(maybe there is a different scale for signal strength) This doesn't just on my phone, as I have 3 that I tested on with the same result. There is no problem with signal as I have said and the phone works fine during this time unless signal is lost totally. Some say TW has faster DATA and BETTER signal, I have never experienced either, both seen just as fast, which is why I wonder if sammy does it on purpose with some code or if AOKP has a smaller scale in which to report the strenght, hench my issue.

Did you actually check the signal dbm or just compared with the signal bars?
The signal bars are just images, therefor, you could set it to show 1 bar and actually have full signal db.
Compare their dbm and you'll see if there's actually a difference.
Another thing, keep in mind that every phone is built differently and one could have 3bars of signal while the other has 4bars, both phones running the exact same thing.

I've noticed the same. On TW I show 3 bars and on AOKP I show 1 bar. I believe it's just as you said the signal image reads off the dbm and AOKP might be set to show 1 bar off -108dbm with TW is set to show 3 bars

Aosp bases roms show signal more accurate then TW based OEM roms. We even found that att had changed some images early on to show more bars then what you were really getting.

Maybe for some folks it's just showing up like that.
But in my area, TW ROM's get me faster & better signal than ANY AOSP ROM. Hands down, flat freaking true. I've tested it with speedtest and speakeasy.
TW consistently gets me a better signal and about 20% faster download speed than any AOSP ROM since the ICS to the current 4.2.2 ROM's.
And not just on one phone either. I've had three S3 warranty phones (don't ask. lol). They all behaved the same way.
I've done "scientific" (as best as I can) tests and it's been very consistent like this. TW just gets a better signal I figure, which = faster download speed. I don't know how else to explain it.
I should also state that I'm on the edge of LTE area. AOSP ROM's usually give me about 1 or 2 bars and 5-12 mbps download speeds.
When I get closer to downtown, I get 30+ mbps download easily.
TW ROM's give me 12-18 mbps where AOSP struggles to reach 12 mbps. In the same exact location on my desk.

The speed is something else completely. That has nothing to do with the amount of bars shown.

Well to be honest it has to do with 2 things. One is how the software talks with the hardware. Second as I stated above. There have been times the carrier have flat out lied about how many bars you have. We found this when ripping the apks apart and there instead of being 0, 1, 2, 3, and 4 bars they removed the 0 and 1 bars and replaced them with the pngs for 2 bars.

Ya its weird, as long as it shows 1 bar, then it will not register signal loss, but soon as that bar disappears, but still with signal, it will register as loss of signal. When there is no signal there is a diff icon, so then and only then should it report as a loss..... I would like to fix but so far I have found nothing concrete, just options.

I think CM shows the true signal bars whereas TW shows the fake one.

A lot of times if it shows no bars yet you still have signal ie. Still able to text, call, surf Web it's because you're transitioning from 4G to H+ or whatever the transition maybe.

Well I have found some info, I am going to try this and based upon the results, I will post back so that anyone that wishes to modify their rom (if it works) will be able to do so.
The problem that I am referring to has nothing to go with the transition from 3g,h,h+, or lte for that matter. connection does not change, problem happens when you are in an area that has a lower signal, thus being able to USE the phone even though there are no bars.
