does anyone know of a kernel that gives better LTE signal rather than the "stock" cm kernel? Kernels like ausdim, AEL,and alurcurd(spell check) kernels on the TW based roms give amazing LTE signal(AEL BEING THE BEST OF THE 3)...i was wondering if anyone knows of a kernel that has the best signal and performance.

So are you saying that these strangely named kernels that work so well and give amazing lte signal are TouchWiz specific kernels only and wouldn't work on cm based roms?

EXACTLY!!!!!!!!! even though they all say only for touchwiz...ive tried them anyways...just to see how it would respond.....but of course it results in a boot loop in which i had anticipated it would.
Maybe cm 12 isn't as great as it's made out to be.
You have to decide razzle dazzle or reliable connectivity.
AOSP or TouchWiz.

At least our AOSP keyboards work properly! :laugh: (I kid because I love!)
The kernel shouldn't be affecting your connectivity. It if does it's faulty. And AOSP connectivity shouldn't be any better or worse than Touchwiz connectivity anyway. Cell reception is more controlled by the physical antenna than anything else. No amount of software is going to make the antenna pick up the radio transmission better, though it can decode it better amid more radio noise.
Ultimately AOSP signal strength isn't bad. And it's plenty stable unless your rom is borked or still in development (which CM12 is)
You got me. :sly:

Maybe this is all in my head so I need a confirmation. Do Sense ROMs have better signal strength/data speeds? It doesn't make sense to me but I just seem to have much better reception and speeds when using a Sense based ROM, including EVO framework ones as opposed to CM and Ruby. Is there ay reason for this or am I just imagining it?
I've often wondered the same thing.
I think, however, that actual reception is tied to the PRL, the radio, the PRI, and some more uber-technical stuff - in other words, things well under the hood that aren't impacted/changed when a ROM is flashed.
That said, I suspect ROMs play differently with those things depending on how they are built, hence what appears (or may actually be) better signal.
It all comes down to the RIL and radio. A rom won't mess with those. They should be identical. Check the signal dBm's to compare roms.

I figured it would be a radio thing but it always seemed it was changing from ROM to ROM. That being said, I switched from a Sense ROM to an AOSP one and the signal has not changed at all so thanks guys for answering the question. I knew it had to be in my head hehe

One thing you DO have control over is the firmware of the radio. There are currently 3 versions of radio firmware that you can flash. This has nothing to do with the ROM. Different people have different results in terms of link stability and speed depending on them. Look for the Radio thread to find the downloads and information.
I've actually had this issue on the EVO and can confirm after testing that the signal strength is less with an AOSP ROM (every one I've tried actually). Drives me crazy because I really want to use one.

How exactly did you test this? There are many variables that could influence signal.
One reason that's kept me from flashing an AOSP rom and keeping it is the latest strength issue. I live in the middle of no where basically but some how I have lte which averages 10+mbps on two but drops to under 2mbps on every aspect romantic I've tried. I there a reason for this and any fixes available?

I'm curious to see what others say about this. Others have said that AOSP ROMs simply display your true signal strength and that's why people think they have weaker signal but you are actually experiencing much weaker signal.
Just for more clarification, if you use an AOSP rom and have weak signal, can you just flash a tw rom and instantly have normal signal?

AOSP roms display your true voice/evdo signal, that's different from LTE/data.
The reason users tend to get less mobile data performance on AOSP is because, essentially, AOSP is ported to our device and to any device that is not a Nexus. That's why we have issues, because people like CM and preludedrew (evervolv) have to work with the files provided to us by the OEM, files which are not compiled for AOSP, but for whatever proprietary UI came with the phone (Sense, Touchwiz, Motoblur, LG UI, etc etc).
However, now with the leak from the S4 Google Edition, we should see all around improvements to the US SGS3 CM10.1 and other 4 2.2 AOSP roms.

Wow you guys work hella fast I might even flash some nightlies now
Edit: If one wanted to could they simply place these files in any AOSP rom they wanted or would it be best to just wait for the dev to do so?

Having more bars on tw is apparently normal. Something about the way it displays the signal is different than the way AOSP roms do it. I don't know all the technical aspects of it. IIRC the bars aren't an indication of how strong your data is though. I've been in places where I had "full bars" but no data at all.
Have you tried liquidsmooth? It's my daily and haven't had problems with LTE. My house is out in a hilly area and don't get LTE there but I do at my friends house and the speed hasn't been any slower there as far as I can tell. 22mb down usually there.
Edit: CNex to the rescue lol

All thanks go to SamMobile for providing that leak lol.
Someone in the CM thread commented that after flashing the nightly with the S4GE blobs, their 3G went from around 500kbps to 1500kbps...but of course ymmv (your mileage may vary).
Sadly the issue still remains the same

I have my Galaxy S3 and my coworker has an HTC Evo. Both of us have Sprint and yet his phone gets 3 bars of reception whereas mine only gets 1, 2 if I'm very, very lucky.
AFAIK, he's running stock, unrooted and I'm running rooted with latest LiquidSmooth 2.9 with the MD4 modem. No idea what modem he has.
What could be the reason why he's getting better reception? Better antenna build in the Evo?

Some of it has to do with the rom. Some aosp roms show a more accurate bar reading...which is why your's is fewer. I wouldn't really get to worked up over it. They both probably get similar reception and data speeds on 3g

I'm going to agree Ivpre. I would not get worked up over it. Unless of course it is necessary for you to have more Bars showing then him :silly: . You do most likely get the same Data Speeds.

I would suggest Updating PRL / Profile. Maybe even trying a different Modem. Not everyone gets great reception on MD4. You may have to experiment to see which works better for you.
If you want to properly know if your device is getting less of a signal you need to flash a TW rom, preferably one which is close to stock update prl and profile. Then check your signal and data speeds compared to your friends. AOSP roms remember are built from leaks, and ported from other devices. There is no true aosp source for the Sprint S3. So there's lots of patches and coding which goes into getting the cdma radios working.

We've actually done a Speedtest together and his had a higher data rate than mine. I've had different modem with the earlier builds of Liquid Smooth as well, but still low reception. I've also updated my PRL/Profile in the past in hopes that it'll help but sadly no.
I'll look into having a TouchWiz ROM versus this one. I just love how LiquidSmooth is, so hoping I can find a TW ROM that's just as fun.
EDIT: I don't even know how to find a TouchWiz ROM. I figured it would say "TW" along the subject line, the same way AOSP does, but alas I cannot find that. I have heard of Goodness, is that a TW ROM?

Some devices just get better reception than others. Better internal antennae.

Most likely cause all the roms which do not say AOSP or CM or AOKP or something like that are TW roms. I would recommend MOAR or TPR The People's Rom.

OP,
Unless you're being very careful with your comparisons and using quantitative, and not qualitative, data like db, seeing more "signal bars" means nothing.
Sent from my buttered S3
You must also keep in mind, that even after you switch to a TW Rom. There is no guarantee that you will see better reception. IE more bars. There are quite a few variables involved. What you should concentrate on is making your device the best it can be for you. As CNexus stated. When comparing you have to compare Apples to Apples, and Oranges to Oranges.

Does anyone know of a custom non-TW ROM that doesn't bork the wimax speeds on this phone? Pretty much any rom I've tried means that my 4g speeds cap at about 600kbps. Then I can flash right back to a TW rom and get ~9mbps. My understanding is that there's something with the kernel that limits that, but does anyone know of a workaround or a non-TW rom that doesn't have it?
I ask because (1) I use my mobile connection as my home internet connection since I'm poor and (2) I hate, hate, hate, hate touchwiz. IMHO, it's the ugliest UI I do believe I've ever seen and I'd love to use a CM rom but haven't found anything that doesn't screw up the wimax speeds. Any ideas?
Thanks.

Here's a screen shot of my 4g in my house in aurora.As for the best speeds, you will have to try ROMs and kernels out to see what best fits you and the area you're in.This is on latest Slim ROM build with lightning kernel P_4.

Sweet, thanks! Any non-TW rom I've tried means I'm NEVER able to get above 600k, so I'll give this one a shot. Thanks again
I think it's a kernel issue rather than the ROM (although many ROMs bundle the kernel with them), source-based kernels seem to cause low 4G speeds for me (slower than 3G), while stock/repacked ones work fine. I've played with all 4 kernels on the Lightweight ROM, for example, and only stock and Agat's repacked gave me good 4G speeds.
I live in the Baltimore, MD area and I'm using Boost Mobile. I'm running JellyBAM android 4.2.2 currently, and plan to switch to CM11 if/when data is working.
Any suggestions for best modem for 3g speed/reception?

Just try different ones... make sure they are ICS modem's though or you won't have data.
Remember... just because we all have the same device... doesn't mean that they run the same. So what works best for you might not work best for another..
Good luck.

I've heard this before, and it doesn't make much sense. Yes, location matters, but two of the same phone in the same location will likely produce negligible differences in reception when using the same modem.

You sound upset... that wasn't my intention buddy. But I can tell you that I have had two epic's and my first one hated JB modem's and my current one gets great signal on JB modem's... and yes it's the same area and no new towers.
Maybe it was the difference in ICS and JB, I'm not sure.
But fl24 is the newest ICS modem and that's what I get the best signal with when I'm running any cm/aosp/aokp based roms... and I've tried quite a few different modems. That was in the Chicago area and Springfield area... both in Illinois.
Also... this current epic runs aokp roms great.. where my first one wouldn't... all chips are not created equal or maybe I just didn't now what I was doing then...
Hope somebody in youre area jumps in with some info for you. Good luck..

No, not upset. My apologies if I came off that way. I work with radios on embedded devices and my experience has been that they all perform within <1% difference of each other when running the same software. Now, it's quite possible to have bad chips, but then all sorts of things go wrong and no amount of software can adequately compensate.
My guess is that ICS vs JB did make the difference for you. And as for AOKP roms running better, maybe it was a different version of the ROM?
Thanks for the input about FL24. I'll try it out.
I have two Epic 4G Touchs in my possession
One of them I can't even get data working on Any AOSP ROMS even though I was using ICS and GB modems.
I now use it as a media device so it doesn't really matter.
My daily driver is the complete opposite.
I get the best reception using FC14 modem.
Unless someone lives in your area with the same phone, they can tell you which modem works best for said area.
