[Q] Can changing Roms improve data speed? - Sprint HTC EVO 4G LTE

I didn't think so but I had been running Mean Rom for months (great rom) and stock before that. On both stock (pre and after rooting) and mean rom I rarely hit 1 mbps, usually was around 500-700 kbps. I switched to deck's CM build yesterday and between yesterday and today I have consistently been hitting between 1.5-2.2 mbps. I know its a small sample size, but it has been at my regular locations, and I did a few tests before switching yesterday morning. What gives? Is this just dumb luck or can different roms actually provide different data speeds?

I have noticed the same thing switching from stock to CM10. I don't have enough knowledge to be sure but I think it has to do with how the ROM uses the radio drivers. Or even how each driver is compiled for the ROM. Then again Stock sense is trash.

What's your EVDO speed?

Saw this on ppcgeeks, I was wondering what xda users' speeds were (rev a or not) on their titan...

titan, sprint leaked rom

anywhere from 200k to 1200k

but, i can't seem to run the test again through opera mini, says to fast/unstable, do i need to clear some cache from opera? so many of these tests seem so off, like running from ie vs opera..
can anyone recommend good websites for testing from the phone (non flash) for accurate results?

I am getting 900k or better on a regular basis, same test site. I cant use speedtest.net for whatever reason cause the phone wont load properly.
If anyone is using other speed test sites, let me know.
I get 200 to 900 on Alltell in Springfield Missouri on the stock ROM. My results are all over the board. It bounces up and down plus or minus 300 kbits from one second to the next in the same physical spot. I check it often since it was my reason for switching to Alltel. It seems strange that it supposedly fluctuates so greatly from one second to the next as Im standing still.

Puts a lot of stress on the CPU to have to both load and render the pages. You see the same effect on a PC if you have no video drivers installed.
There's a non-Java test at www.mobilespeedtest.com. With ROM version 2.09 and only PIE running, I got top EVDO speeds around 955kbps when testing five times in a row, with an average of about 865k when throwing out the one-time 245k result.

Data Speed vs. Captivate

Is this phone supposed to be any faster than the Captivate (Galaxy S), data wise, assuming one is in the 3G section of the AT&T site and the other in the 4G section, or is there really no jump at all? I just tried a speed test with a Captivate and my GSII, and both showed the same speed on speed test which is pretty weird in my opinion...
Really depends on your area, in socal valley I can run a captivate right next the SGS2 and get the same results with the captivate slightly slower with uploads (fixed usually with a I9000 modem)
That's what I did too, haha...Put a Captivate and GSII next to each other in SoCal, and the speed was the same, so I was like =0.
I am in a HSPA+ service area, on my captivate I almost never saw more that 2Mbps down, I see just over 3 on my i777.
Sent from my Galaxy S II (i777)
I'm getting way better speeds on my SGS2 than I was getting on my Captivate. I have my gs2 stock, but it's still faster than my Captivate stock, with stock froyo, and with numerous roms. I don't remember exactly what my speed tests were with my Cappy (around 1.5 - 3 DL and .5 to .8 Up), but I'm getting 6+ to 8 DL and 1.5 Up with my sg2
Depends on if you have a real H+ coverage?
To me it's about 3 times faster than captivate in house.
Was getting 600KB/s in a 3g area whereas the captivate only got 300 (no HSPA+ in my neighborhood)
Sent from my SAMSUNG-SGH-I727 using xda premium
when I used to use the speedtest app, I got the same data speeds on my captivate and my gs2. As soon as I used the speedtest via the browser, it showed the speed difference.
Yeah, this makes more sense, the browser application and the speed test application have varying numbers...I guess speed test application =/= reliable
yeah, its documented in a few places that the speedtest app is not reliable (maybe on some devices?)
I use the FCC speed test app, more accurate results
I know this is an old thread but I didnt want to start a new one for this. I have been running side by side speed tests with a captivate running cm7. On my gs2 I'm running unnamed 2.1.1 with the UCKK6 modem. I am consistently getting better speeds on the captivate than I am on the GS2 (sometimes over 1+mbps higher) The gs2 has never gotten higher speeds than the captivate. I've tried different modems, Ive run the FCC speed test, the normal speedtest app and the speakeasy.net website all yielding the same results. I'm in an area that is supposed to have great HSPA+ coverage. I just dont understand why my GS2 isnt getting higher speeds than the captivate since it's HSPA+ and the captivate is only 3G(if I'm not mistaken) Both phones were new orders so new sims, service etc..
My captivate RARELY got to 4mbps. My sgsII usually hovers around 6-8mbps

my Gs2 hasnt gotten over 4 yet
Just now I went outside and did a speed test. my captivate pulled a little over 4mbps and my gs2 was at 3.
Yeah i guess i have to try to different modems and settings because my captivate was pulling 5300 down and 1100 up and my GS2 is only doing a meg faster down and the same up. It kind of retarded that i had to switch my sim card to a 4g one if my speed did not really change. Does anyone know if the 3g supercharger works for 4g. I was going to ask Zep but i figured id ask here since i was making post around the subject

??? What 3G supercharger?
http://forum.xda-developers.com/showthread.php?t=991276&highlight=v6+supercharger
Zepplinrox's V6 supercharger Kick Ass Kernal (KAK) Tweaks and 3g turbocharger. You have to go to the 4th line down where it says most recent files here to get KAK and the 3g turbocharger. It worked pretty well for my captivate. I think im going to apply it to my SGSII even though its runs as smooth as can be just because i like overkill lol
/me gets popcorn while awaiting results.
I'm in Dallas, TX so AT&T coverage is not an issue here, and I get the same speed on the Captivate and the SGS2 an average of 3mbps down.

lol Zep your the man. Well i havent had time to try all settings thoughly to get a clear and concise judgement on the 3g turbocharger. I started off only getting around 6.3m down and 1.1m up. I ran tweakker and my next tests immediately after were all around 5.6 down 1.1 up. The next day, however, they jumped up to around 7.4 down 1.1 up. I applied 3g turbocharger fastest and experimental and test after that were around 8.3 afterwards. I ran the test five to six times on speedtest.net. I need to create an acct. so i can track this stuff. I was using the app but the app was showing 2m less consitantly on my down speeds. i really should have ran my phone longer after using tweakker to make sure around 7.4 was going to be my norm peak.
I applied V6 supercharger through build.prop and integrated running die-hard & 1000hp and also applied KAK tweak with I/O tweaks off as my phone locked up when i applied the I/O tweaks but thats probably because mine is set to CFQ. Dont know why and will probably set it to deadline. The one thing this fixed for me was the transition using the browser. Going in and out of the browser was never as snappy until now. I just cant slow this MFer down. I was concerned that i let my impatience get the best of me picking up this phone instead of waiting on the next gen as i only get a new phone when i can upgrade every 18 months but i have no doubt this phone will last me the next 18 month easily. Thanks to Entropy512, GTX465x, and Zeppelinrox My phone runs buttery smooth and i have not yet stumbled on a single hiccup. My hat is off to you gents. I feel like my phone is set for overkill and ICS still isnt out and i havent tried to go to 1600mhz. Mine is running @ 1400 BTW and under volted by -100mV. I have a feeling my next phone upgrade is really only going to be for a better screen and camera as speed probably wont ever be an issue.

I know everyone loves ICS but GB is faster

Truly is ICS better than Gingerbread in real life [on the EVO 3D]? I find myself flashing multiple ICS roms hoping to gain the smoothness of GB but I just can't find it.
I know the features ICS brings are great:
- Chrome support
- Better sleep management
- Better system/data management (cant confirm this)
- 32 bit color by default (cant confirm this)
** http://www.android.com/about/ice-cream-sandwich/
But one thing GB has that ICS doesn't is complete capability with our phones. We were able to make GB fly and I feel since Sprint is dragging their feet to release the update, we will have some time before ICS flies like GB. By then Jelly Bean will be running. It's a vicious cycle.
I am all for trying out new software, I love being on the bleeding edge of technology. However, for example, when playing Max Payne on ICS, the joystick would stop responding or the framerate will drop dramatically. That never happened on GB.
So my question is, whats your reason for running ICS on your EVO 3D? It is because its the latest and greatest or is there a certain feature I am missing? Because I am starting not to see a benefit.
**Disclamer: I read a couple of threads related to this but this subject was never expanded on. Mods feel free to close if you think this is redundant.**
I run it because I'm yet to have 1 problem that's not a known ics general issue.
Sent from my Evo 3D on Sprint's blazing fast 3G network with 4G coverage everywhere
For cdma phones yes, the 2.17 base was an excelent base for GB roms. Us poor GSM users had a crap base which when even overclocked was probably still slower than the current ICS.. for example low 2000 quadrants and 24fps nenamark
I just wish there was a way to use the 2.17 base roms on GSM, I would certainly use it. :good:
ICS runs fine on my phone. And I'm easily getting at least 24 hours per battery, as opposed to 12 hours with GB.
ICS definitely has better battery management. However, for me personally, I don't mind having less battery with more performance since I have multiple batteries I can just swap out. A perfect balance is what I look to achieve. ICS beats GB in terms of battery life but I have to give the best performance title to GB.
Wait until HTC release the kernel sources and we get custom overclocked kernels, will speed it up a little

There hasn't been an official ICS release? (For CDMA at least). Generally its been a 90 day or so time frame for source release. We should see GSM source in the next couple of months. While HTC isn't the fastest at releasing they haven't ever failed to release source that I'm aware of.

Disagree with this post 100%.
Even though im running a GSM version, i can tell you right now that the phone is 100% different then the GB version. Its faster, smoother, and runs far more efficient. (ive only got 200 mb used of ram, when my GB version was running around 400-450, and i still have to remove junk from my ICS version once i root it.)

Again this is for the GSM version, it may not be true for CDMA phones as i doubt you have one to compare...
I myself believe the fact that their phones run worse on ICS then ours because the same thing was happening to us on GB...
I think for me gb gave me problems with youtube....always skipping in the middle. But going to ics has fixed that. Everything is smoother. Battery life to me isn't much of a problem since I have about two extra batteries.

ICS runs way better than GB did. side by side comparisons of Eternity 1.4.2 vs inbREDed 5.2 verify that for me in an instant.
apps load faster, menus react quicker, etc. I'll never go back to GB and can't wait for an Anthrax kernel for this.
I do wish that the Sense 4 ROM's had 3D and 4G though, because those things run really, really nice.. *sigh*
Interesting feedback, thank you everyone. This is definitely "food for thought".
Whats your feedback on game performance? I usually find myself playing one of the Rockstar or Gameloft games I have purchased and I feel ICS framerates drops much more than GBs.
I feel that since GB's kernel source has been released, devs were able to tweak it for maximum performance under heavy load vs a stock kernel which would be somewhat conservative on performance.
And yes I do have a CDMA version but input from GSM users are welcomed.
Hate to be the one to say it but the second our devices are graced with JB performance and battery life will not just reach the best balance yet, but take both to new levels.
Were in developmental limbo right now, and shortly enough new JB roms will start pumping out, keeping users happy for quite a while

Not everyone will jump on JB. I know I won't. I have good 4G coverage and want to keep that, especially since my speeds have been going up. and I want to keep 3D. So if those aren't present I'm staying on ICS
I really wish we had a stable build of CM7 for CDMA to play with, htc holding the source on ICS kernels has made the ICS dev basically come to a crawl and it saddens me lol... My old Evo4G had a new ROM out everyday it seemed and IMO CM9 was more stable there than on the 3D. Nothing against the wonderful devs here as it's not their fault htc is being stingy with source.

I don't actually have an evo, but I've been using an HTC hd2 for a long time, until yesterday.
I was running the latest ics version mostly just to be on the bleeding edge of technology. Their were a few things I really liked more and reasons I wanted to run it because of, but mostly i wanted ics because it was new.
We also had gingerbread roms that were blazing fast and worked almost perfectly. In all honesty they were amazing.
Then ics came along. Many of the drivers were not there for our device and the devs start working like crazy to fix them or write them, just whatever needed to be done.
However even to this day ics does not run as well as gb did. It is very stable, not a lot of fc's but it still has some. In reality its just not yet the same quality gb was.
I think that until HTC releases the kernal source like for the evo and other phones that ics will not run as good as gb. In no way is this in offense to the devs. I just know that its hard to match a companies time and man power when your doing something for free.
In short, unless their is a lot of official support I do not think ics runs as well as gb either.

LTE speed between MIUI and custom ROM

Hello,
firstly I apologize in the advance if there is a such thread made for this issue and if I opened the thread in the wrong location.
Now, regarding the issue is with the LTE speed between original MIUI and custom ROM. I have tried all custom ROMs: Lineage OS, Havoc OS, Nitrogen OS and Pixel Experience. All are working perfectly with one big downside and that is LTE speed. With MIUI I get full LTE speed about 50-70Mbps, HOWEVER with all custom ROMs I get LTE speed strictly limited to 4-5Mbps for unknown reason. I flashed different vendor firmware version, I even tried with root and without root. Sadly I got same results.
All I know that custom ROM is based on AOSP so I assume there is something missing something. I live in Europe, in country Slovenia.
Is there anything worth trying to fix LTE speed in custom ROMs? I have the global version Pocophone F1.
Thanks in the advance for the help.
LOL!! 50-70MBPS?? Do you actually see 50mbps while downloading or uploading? If yes, I would like to see some proof like a screenshot where a big file is getting downloaded on Google Chrome and the speed is showing 50MB/S. FYI, there's a huge difference between speed on a speedtest app and in real life usage. I have never noticed any speed difference in between PE and MIUI in real world. Maybe that's because I don't believe in fake results on SpeedTest apps.

Um... I didn't write MBps.... I wrote Mbps and those two units are not same... 50-70Mbps is equivalent to approx. 6-9MBps download speed. Well, to show the proof, I need to reflash MIUI again which I don't want it for now. I tried downloading any apps, files, movies, music... etc on Opera, Chrome, Firefox in all custom ROMs. All were shown to 500-600KBps download speed. I'm currently on Havoc OS.

Can be a possibility of not getting Carrier Aggregation (4g+ or 4G LTE CA) problem on custom roms? Do you see 4g+ on custom roms? I'm on custom rom and getting 70-80Mbps (7-8MB) download speed .
@Rowdyy Ronnie not sure if you thought OP meant 50-70MBPS or 50-70mbps but I'm easily getting above 70Mbps (7MBps+ download speed) on 4G in India with JIO. Probably poco is the only phone which gives me best 4g speed as compared to other phones I use. This is why my JIO number is always in Poco phone.

No, I don't see any 4G+ or 4G LTE CA in any custom ROMs and it is same with MIUI because it also shows 4G, yet in MIUI I get far better download speed... I'm quite confused... Maybe (hopefully) will something change when we switch carrier, though I highly doubt it will change anything.

Brother, at the lineageOs is written that It enables a lot of new bands(LTE). Do you know if this is true ?
I was having this issue in mind to talk about and good to see I'm not alone. I have tried hell lot of ROM, Kernels and almost all beta vendors+firmware combinations sometimes on recommendations of others as well. For example people say all 9.4.* ven+fw are bad for LTE speed.
I would like to know if you have tried latest Stable ven+fw for your existing custom ROM, this would not always match MIUI LTE speed, but will be close enough. Try this - https://mirror.akhilnarang.me/MIUI/beryllium/beryllium-V10.3.5.0.PEJMIXM-9.0-vendor-firmware.zip - specifically and update with a test results.
Also, LTE Discovery (a root app from Play Store) helps knowing in what cell tower you are connected to and if the behavior of speed depends on that. The strength of signal and direction of cell tower are to be noted.

From the screenshot, the phone is connected to band 3/1800 Mhz frequency which offers less speeds. The values of RP/NR are also low which means you're in low coverage zone. In my country, this band max output speed is 18Mbps. I don't think you will get 50-70Mbps in this band anyway.
Here's an easier explanation of how this works:
Best coverage: Band 5 > Band 3 > Band 40.
Best speed: Band 40 > Band 3 > Band 5
Check atleast 1-2 times a day to see if it latches to B40 which would give you maximum speeds on LTE/4G. Every country has it's own bands so you have to check yourself which band your operator offers to you. The above example is from my country network operators.
In case you want to test why you get more speeds on miui, flash back miui and check which band the phone gets connected. There can be plenty of reasons for low speeds on custom roms, may be it's related to vendor, network issues, signal at that time, band connectivity etc. It's not easy to find out an answer as to why you get low speeds on custom roms but it's not like custom roms provide low speeds on lte, I'm getting same speeds on both custom and miui roms.

@vijay-in I have been using beryllium-9.6.3-9.0-vendor-firmware.zip. I also tried all different vendors, sadly no avail... I will try this vendor though I doubt it does any changes regarding LTE speed because LTE speed worked in MIUI regardless of vendor versions. Going to try that vendor you posted. And I'm using latest Havoc OS.
Edit: no changes. I'm using beryllium-V10.3.5.0.PEJMIXM-9.0-vendor-firmware.zip and nothing changed

I am using OxygenOS port from 6T beta, and the stable vendor has changed things regarding LTE certainly, I was getting maximum 10Mbit on Band40, but now it goes up to 30Mbit sometimes +.
I see you are in Band 3 (1800) coverage which has the worst bandwidth 5MHz instead of 20MHz (at some places 10MHz) of Band 40 (2300) and 10MHz of Band 5 (850). Ideally as mentioned in other comments, Band 3 should be faster than Band 5, but not in case of Jio at most places. The bandwidth is very less and Band 3 ensures you get pathetic speeds.
Try moving to the part of your house and find the spot where you get Band 40 (or Band 5) and try speedtest. I have identified some spots in my house where I get 30Mbit and when I have to download in GB, I get there and fire You can use LTE Discovery from Play Store as I mentioned in last post also.
Edit: No offence to anyone, but in my opinion locking band using Network Signal Guru may prove to be disastrous sometimes and you can be without network in some places when you need the most.

From the screenshot, the phone is connected to band 3/1800 Mhz frequency which offers less speeds. The values of RP/NR are also low which means you're in low coverage zone. In my country, this band max output speed is 18Mbps. I don't think you will get 50-70Mbps in this band anyway.
Here's an easier explanation of how this works:
Best coverage: Band 5 > Band 3 > Band 40.
Best speed: Band 40 > Band 3 > Band 5
Check atleast 1-2 times a day to see if it latches to B40 which would give you maximum speeds on LTE/4G. Every country has it's own bands so you have to check yourself which band your operator offers to you. The above example is from my country network operators.
In case you want to test why you get more speeds on miui, flash back miui and check which band the phone gets connected. There can be plenty of reasons for low speeds on custom roms, may be it's related to vendor, network issues, signal at that time, band connectivity etc. It's not easy to find out an answer as to why you get low speeds on custom roms but it's not like custom roms provide low speeds on lte, I'm getting same speeds on both custom and miui roms.

Okay, I flashed to original MIUI and sure enough, it is way weird.... http://prntscr.com/o42grn Here is the link of speed using Opera with LTE and right picture is taken from Network Guru. I don't see difference at all except LTE speed.... I'm seriously baffled... I probably can live with 600KB/s download using custom rom. Way weird bug or my phone is haunted to the hell...
Edit: I took this screenshot on same spot while testing the speed. Here where I'm sitting right now, I get full LTE speed on MIUI, on other hand with custom ROM, I get mere 600KB/s...

That's weird for sure If this is same with all custom roms, there is something wrong with either all of them or the stock MIUI
You have 20MHz bandwidth in Band 3 which is different from what we have here, so my previous answer was incorrect. So, you have a strong and fast Band 3. Probably it is the best in your country and has nothing to do with difference in results.
I am sorry that there is nothing much one can suggest, though I sincerely hope someone would help you with this. One thing you can try is, flash many popular custom roms over weekends and see if anyone can come near that speed, difference of this fold is quite unbelievable.

Do you think there is something in AOSP because all custom ROMs are based on AOSP and (just loud thinking) I assume devs didn't add any files in AOSP or something for Europe to boost LTE speed? Though I'm not really sure but I know that MIUI has something that gives a full LTE speed while custom ROMs "restricting" LTE speed because in all custom ROM, I get 500-600KB/s, no more, no less... I'm sadly not a programmer/coder so I cannot investigate it myself...
I see you have used multiple vendor+firmware beta/stable and have had same results, but I still think it is related to modem firmware, though I maybe absolutely wrong and it is not logical as well.
As you have nothing to loose, please try a really older firmware which is known for not having speed bug. Just firmware, not vendor.
Go to ip dev's GDrive https://drive.google.com/drive/folders/1zGc3v1ahsN2dpkPppNAJJMDHKl8jnQmj go to xfiles and download POCOF1Global_9.3.28-firm.zip (91MB)., this has only firmware which could be flashed in TWRP.
See if this helps. You can also try latest stock MIUI kernel from same gdrive - kernel-beryllium_global_V10.3.5.0-ak3.zip - on Custom ROM and see if that makes any changes.

I tested both and it became more weird again... xD Speed increased by mere 100KB/s but... Youtube app doesn't play at 1080p and it buffers way badly than on previous build... :/
May I ask how is the Oxygen OS? I would like to try it out as well.

Strange things happening with your LTE
Newer 7pro ports are kind of pre-alpha and have bugs. OOS 6T Beta 10 was the last in that branch of development, which I use as daily driver, it is best per my opinion after trying lots of roms, especially if you play games. You can definitely try it if it resolves your LTE issues.
The dev has taken down links, but I have it mirrored for myself http://dl.vj.lc/Poco-OOS/ Flash OOS zip only, it has vendor included. Test it that way.
Later on, update to newest vendor and flash vendor_patch.zip. Whenever you flash new vendor don't forget to flash vendor_patch. Latest is now 9.6.18.

Thanks! I will try it right now. I will inform you shortly on how it goes :good:
Edit: why did he disable links? Just asking because I peeked and I saw latest version... quite odd...
Edit1: Okay, it is literally same thing with LTE... though Oxygen OS is very smooth and I quite like it but LTE speed... is quite severly limited... Maybe something is wrong with the my phone and I need to RMA it... I really don't know... Your Poco F1 works good... so why... :crying::crying:

Besides MIUI, are there any other ROMs with good WiFi/4G speeds?

Hi there,
So I'm on crDroid, and have been for a while, it's a great ROM, does everything I need, and works great without root. I have noticed my 4g and WiFi seem a bit slow though, I can be sat right next to my router, and get less than 1mb/s, when my net is capable of 10mb/s. Now, I don't have another WiFi device to test this properly.
I have also noticed that my 4g is pretty slow too, now that's probably just down to my network, but I can only get like 5mb/s max when I'm outside with full signal.
Are there any ROM's people would suggest for the best signal quality? Both WiFi and mobile data. I'm not a fan of MIUI, as its aggressive battery management and app killing just wasn't what I was used to, used custom ROM's on my phones for the longest time!
I don't use root, so being able to pass safety net and use banking apps etc is a must.
Thanks,
donk165
Scrap that, seems my speedtest app was bugged out, the speeds seem better now, managed to get 10mb/s at work inside a building on 4g, and on the work Wifi, im getting 100mb/s up and down. crDroid is fine
How is this crdroid for gaming? Do you play any games?
