[Q] HSDPA:9 on ICS Versus HSDPA:8 on JB - Samsung Galaxy W I8150

Hey, Yesterday I flashed back to CM9 and saw the data connection speed on that ROM was HSDPA:9. I compared to CM10 and CM10.1, and I found that the data connection speed on this ROM was only HSDPA:8 which is lower that ICS. I Googled a little bit about them and I found this link which has an explanation about the difference. 10.1 Mbps versus 7.2 Mbps was even lower than data speed that our phone capable of doing. our phone should have like 14.4 Mbps speed, right? so? it should be getting like a HSPA+ on our phone if im not mistaken.
Questions:
1. is there any chance that this is happening because we are using Custom ROM?, or
2. Did Samsung lie to Us about the phone capability of reaching that kinda speed (14,4Mbps)?
3. did this happen because of the provider? (well, I'm not sure about this, coz I used the same provider but the data connection speed are different between ICS and JB in My phone. and one more, In My friend Tablet, He could reach HSPA+ by using the same Provider as mine, so...)
Any Thoughts would be appreciated.....

[Q] 3g Data Speed Reduces Over Time

So maybe I'm crazy but it seems like the longer the stay on one rom the slower the data speeds get. I flashed a rom this morning and my 3g data was 2,000+ Kbs and by the end of the day (when i would assume network traffic is lower) I'm down to 300 Kbs.
Anyway just curious to see if anyone else experiences this and if so someone has a fix.

How do I improve data speeds on T-mobile?

My galaxy nexus usually does 2.5 mb down and 1 up. It also usually says 3g, and when I start using the phone 4g "kicks in." I am using it on t-mobile right now. Is there anyway to get faster speeds?
I used to have a t-mobile galaxy s2 and would get anywhere from 6-10 down in the same area and 1 up.
Thanks.
Your experience with the phone switching between "3G" and "H" is normal and the way it should be working.
As far as speeds go, I'd tell you to possibly change radios and/or check your APN settings to see if you can improve the speeds. These are the usual simple "fixes" for data speeds.
With my experience with unlocked phones... I've tried flashing different radios and it generally improves speeds.
I haven't really had to mess with APN settings though.
So far I have tried: the stock radio that shipped with the device, XXKL1, and XXKK6, with about the same speeds
If anyone has t-mobile and can point me in the right direction for better speeds please let me know.
Also--how fast are the overall data speeds you guys get?
I'm on T-mobile with XXKK6 all stock 4.0.2 and my normal speeds are in the 6mbps down / 2.5mbps up range. My highest are about 9.2mbps down / 4mbps up.

Has it always been this slow? Maybe your data is being throttled.
No idea... I guess I'll check. It's not slow by any means though just my t-mobile galaxy s2 picked up the signal a lot better since it had nearly double the speeds? I'm in Phoenix so I generally have excellent coverage too...
I'm getting 3.5-4 down and 2.5 up with XXKK6 and franco kernel
The numbers you are getting are pretty normal for TMobile. The galaxy s 2 theoretically should get better speeds, just because its max theoretical speed is twice as fast as the galaxy nexus' on the same network. Your speeds will carry depending on where you are, time of day, etc.
I remember on previous phones including Nexus S there would be a build.prop hack to make your speeds faster. Not sure if it works for the Galaxy Nexus but here they are,
ro.ril.hsxpa=2
ro.ril.gprsclass=12
ro.ril.hsdpa.category=16
ro.ril.hsupa.category=8
Click to expand...
Click to collapse
Add those to build.prop in /system/ (may require additional tweaking since NS is only capable of 7.2 Mbps)
I don't know if anyone is still monitoring this thread, but I went in to a t-mobile store yesterday and watched a One S get 21 meg download speeds on 4g when I can't get better than 3.5 with my GN. I've tried different radios, nothing changes. As though I am throttled at 3.5- which I am not.
Any ideas?

[Q] SGH-T989D (Telus) Slow "4G" on T-Mobile

Hello all!
Noob here, first post, so first and foremost please pardon any ignorance. I did search here as well as google without finding any significant results. I appreciate anyone who takes time to answer.
I recently bought an unlocked Galaxy S2x (989D) for use here in the USA on T-Mobile. I went with the 989D and not the 989 because I'm using a grandfathered T-Zones plan.
I rooted/flashed Juggernaut 5.0 through cwm, and the phone is working fine EXCEPT my download/upload speeds are lousy. Consistently 1.5Mbps down / 500Kbps Up MAX with 800-1200 ms ping via speedtest app from various parts of Maryland (Baltimore/DC corridor) and using different servers. My N1 has always tested faster than that in the same area, which is why I'm particularly concerned.
I tried flashing Telus KJ3, T-Mo KID and T-Mo KL1 modems found here:
http://forum.xda-developers.com/showthread.php?t=1426001
But saw no improvement. I've also tried using the stock epc.t-mobile and the old internet2.voicestream APNs, with equally crappy results on both.
Is it just a matter of T-Mo having terrible speed over HSPA in this area, or is it possible that there's something screwy going on with the device/rom/kernel/radio? FWIW, calls and texts are fine, and wifi calling works as well. I've attached a few screenshots in case any of them might be helpful.
TIA!
hmm... you should read this http://forum.xda-developers.com/showthread.php?t=1514954
there's no spoon
highest speed i ever got was close to 10 Mbps in Canada 3G/3.5G networks
seems more like the area you live in, have poor Tmo coverage for data
That's disappointing, to say the least, especially since according to the coverage map, I'm smack in the middle of a giant blob of "4G Excellent" coverage. I'm still confused as to why my Nexus One would have better speedtest results. Perhaps HTC/Google FTW.
seriously???
Is this legit? Full 4G signal? I can't imagine how it's THIS slow. Does jugg 5.0 have any build.prop tweaks that could be farking with my data? Just threw my sim card into my N1 to compare and it's way faster.
@JoshD422, Did you ever figure this out?

I am also wondering about this same fact with a real Telus phone in Canada. I'm also wondering about the difference between the 3 radios that were provided with the Darkside.UCLE2 Beta 5 ROM. (Don't get me wrong, appreciate all the hard work from these guys, amazing where the T989 dev has come already!)
I tried all 3 radios, and get different speeds with each one. Blazes 4G radio I can't seem to tether, and then the T-mo radios I'm having issues with Bluetooth and even Data.
Could someone if you have a minute explain what the difference is between the radios and maybe suggest what radio would be best for us Telus users in Canada?
Cheers, TIA!

JoshD422,
I will be the first to tell you living in Toronto, that its completely unpredictable in Canada.
I've had areas if there is high use downtown I will get even worse results than that (seen a ping of over 1000ms ).
At the same time I can redo a speedtest about 200 metres away, and get results up in the 10 Mbps and pings of 45 ms. So I don't believe that part has to do with the radios but more the quality of service, and I'm in whats supposed to have the best service city in Canada.
Your problem definitely seems to be due to the T-Zones plan. I don't have that plan and I'm using an unlocked stock Telus T989D in Maryland and I get 2-4 Mbps down and 0.7-1.0 Mbps up

Do you get the "4G" icon?
I am on a stock unlocked T989d in the Atlanta area and get similar speed to you. However, I only see the "3G" icon in my phone.

Yes, only "3g" icon in MD/DC area. I guess maybe perhaps this is not as fast as using the T-Mobile radio software that comes stock in the T989, but it's plenty fast for me. I don't think the "4g" capability is much faster, anyway.

I think the "4g" icon is purely cosmetic. I have an unlocked Telus T989d on Tmobile and my co-worker has the Tmobile T989 on Tmobile. We both did a Speedtest side to side and we both got ~12Mbps down, ~1.3Mbps up. My phone was showing the 3g icon, while his was showing the 4g icon. Both our networks showed up as HSPA. Both of us in our respective stock, un-rooted ROMs.
While T-Mo roms do tend to be a bit over zelus with the 4G icon, it is much faster than a 3G connection. Where I live in Orlando is a 4G area and I get over 20mbs download speeds and over 2mbps upload speeds..
Side note though.. it is funny that people still use "" or call it 3.5G when the T-Mobile network has been accepted as 4G for almost a year now .. I tried to find the artical but its being illusive today..

Officially, 4G is supposed to get 1000mbs peak download. Tmobile uses HSPA+ which peaks at ~80mbs. I think that is why people call it 3.5G or use the "4G" when talking Tmobile.

How to run utms(3g) instead of hsdpa(h)

I have wind galaxy s3 and I installed cm10 for t mobile. Obviously there isn't one for wind so I had to. Well I soon noticed my data is slower. Normally on 3g I would get 6-8mps but since I installed this I'm getting 2-3mbps. And I checked its because my phone isn't using 3g its using 3.5g(hsdpa). I have been looking everywhere but haven't found an answer yet. I was wondering if anyone can extract winds modem file I can try installing that.
I have already tried a lot of tricks from service menu but nothing works. I'll still try if you anyone have a good advice. Thanks
If you flashed CM10 for the T999 on a Wind Galaxy S3, which is what I understand you to mean, then you should still have a Wind radio/modem. CM10 doesn't flash a radio unless you have customized the package for some reason. And why do you think that you would get slower speeds on HSDPA as opposed to UMTS only? The phone is going to use the best that it is capable of, unless you tell it not to do so. I do know that CM9 and probably 10 also was said to have slower data speeds in general on some devices. I don't personally know if this is true or rumor. But, that may be your problem.

Yes you got it all correct, Wind actually uses 3g mostly so it has better service on 3g(utms) vs on 3.5g(hsdpa). hsdpa works but not as good as 3g could when i had stock rom and thats the band(3g) my phone used before mostly.
phone is using what logically should be better but stupid wind likes to be on old technology.

[Q] Weird data speeds when switching from Wi-Fi to 4G

Hello everyone, I'm new to the forums and wanted to start out by asking a question about my phone's performance. A month ago or so, I've updated my T-Mobile Samsung Galaxy S II to ICS 4.0.4 (Stock Android). Before that I was running Android 2.3.6 to which I reverted from ICS 4.03. Anyway, to make a long story short, I've recently noticed a problem related to data speeds and I know for a fact that it's not a network issue, but a problem with my phone.
Basically, what happens is that when I have Wi-Fi switched on for a longer period of time and then switch to 4G, my data speeds become slower than what they should be on the 4G network. I live in a HSPA+ 42 Mbps market (NYC) and normally get about 15Mbps down on average with latency in the 80s. However when this problem happens and I run a speed test I tend to get less than 10Mbps on average. For example, today I was getting 8.38Mbps down and 1.15Mbps up with a latency of 98ms. Now I know that some of you might say, that I shouldn't be complaining, but just hear me out. When I switched my phone to Airplane mode and then back to mobile data, all of the sudden my speeds were 19.08Mbps down and 2.99Mbps up with a latency of 73ms. It was also tested on the exact same server and only one minute after the first test. I've also noticed that the exact same issue appears to happen when I'm not using mobile data for a longer period of time.
Other than rooting my phone, I haven't really done anything to it, so I'm wondering where this issue could be caused by a bad ROM flash. I'm debating whether I should reinstall the ROM and whether or not that could fix the issue. Just wondering though, whether anyone else noticed this problem with their phone running stock 4.04?
