Status of AOSP?

Did the JB leaks help AOSP roms w.r.t data speeds, stability, camera etc? I don't see much going on, is everyone waiting for 4.2 to drop?

I think so.... Tomorrow is the suspected drop of the nexus 4 so yea I guess so.

The big issue is the kernel. And the source for the JB kernel isn't out publicly. So no one has it to mod or tweak like the AOSP guys need. Once the OTA drops and the kernel is released AOSP will be rolling all over again with much more steam.

There are quite a bit more data drops on AOSP as opposed to stock TW. Also AOSP doesn't pick up signal as well as the new JB TW leak in outlying areas. For instance I get 1 bar of 3g and 1 of 4g in my house on AOSP and on the JB leak I get between 3 bars to full service on 3g and between 2 and 4 bars on 4g in the same place which is a great improvement over TW ICS, I was dropping service all the damn time for no reason. On my MAXX I had full service on 3g everywhere on my house and 3 to 4 bars of 4g, and while I know Samsung radios aren't as strong I shouldn't have had that much of a problem, my SGS3 wouldn't even pick up service much better outside until the leak.

That's interesting. I've never had any data drops whatsoever. What's the differential on the actual numbers? Bars aren't a good metric.

It isn't a gargantuan difference but it is notable, I'm not home and won't be for a bit, I have a notebook I've written it down in, but later today I'll flash the new leak grab the numbers and grab the numbers off of PA and post them for comparison. The thing that killed me though was that the numbers were closer to TW ICS, there was still a difference but not as large as AOSP and TW JB, but the difference in the service quality was notable. Texts didn't fail 5 to 10 times and have to be continuously re-sent, and calls weren't breaking up any more and I wasn't dropping calls in the same place I had all of these issues before.
I'll try to post em all by 5 today, hopefully.

My experience on AOSP is that for the first few battery cycles my signal will be fine. Then as I get more situated on the rom (any AOSP one) the 3G/4G hand off gets worse and signal degrades. Touchwiz definitely gets me a better signal, one that is consistent at that. The signal difference is far from negligible in my experience

Aosp imo has lost its edge...reason being everybody is using cm's kernel base so they all have the same bugs. I dont know if its the abundance of supported devices thats taking away from the quality of the builds. However it will shine over touchwiz when the carrier quits updating the device and the only way to get new versions of android will be thru aosp.

Poor Signal Strength with Cyanogen 10 & 10.1

I live and work in an area that has poor signal for Verizon. I almost immediately flashed to CM 10 after I got the Verizon Galaxy S3 because I was running CM 10 on my previous Sprint Galaxy S3 without issue. I have been updating the radio and RPM with each leak (currently running K3) and things got a little better but I constantly dropped calls. I had to flash back to stock because I flashed to CM 10.1 and my radio got messed up. I ran the newest stock rom for the last week and noticed a huge difference. I still had low signal but my data dropped less frequently and I could actually make phone calls in areas I couldn't before.
I rooted, and flashed to CM 10.1 and noticed right away the signal is not where it should be. I can't make phone calls inside of buildings with low signal at all, where with stock I could without issue. I love CyanogenMod but I don't think I can deal with the poor signal.
Any ideas on what could be causing this problem and maybe a possible resolution?

Depends on where ya live, your mileage may vary. I get within 1-2 -dBm between the two.
Technically since we don't have the source code the reason CM10 has data is by a work around.
There really is nothing you can do. It is what it is. I've run devices with CM that have provided better signal, and usually were on sprint lol and then run them where they provide the same or slightly worse quality.
Happens.

This does not ha e anything to do with cm 10. This this to do with the the phone radio. This is the reason why I switched to the DNA now I have Full bars everywhere I go. On my s3 I used to drop calls all the time.

Ok I really hope I'm not beating the dead horse here but I have a similar problem on my verizon Galaxy s3 and I was hoping there might be a fix

My understanding is that the CM developers dont have the GS3 source for something (the RIL?) so they have to use a different RIL? I'm probably totally butchering that, because I dont understand the words I'm using, but from what I've gathered the signal is what it is on CM, and will not improve beyond where it is.
It is certainly usable for me, but there are many times my wife has 4g and I have 3g, or she has a 3g signal and I have nothing at all (she has a stock vzw gs3).

I think you're correct on the RIL part.
I had the same issue on 10.1. I switched to an older radio, and though it is not perfect, it did give me better reception and the switch from 3g to 4g is faster. My radio is VRLHE

Why not try a rom like beans. It is a touch wiz rom that looks like aosp and had a lot of aosp features. That way the radios will work fine you will still have aosp stuff and all the goodness of being rooted.
Sent from my SCH-I535 using xda premium

Let's not get confused here. Tw rom's like beans are themed to look slightly aosp, but are far from it. Aosp has so many customization options that tw cannot come close to. (I'm an aosp guy, if you can't tell). That being said, signal strength will always be an issue on aosp based roms due to the Samsung ril only being licensed to samsung, hence only working on tw rom's. The official ril code will almost never be released as its how qualcom makes its money. Currently aosp rom's use a work around home brewed ril that is very effective, but not quite what stock rom will offer. So if your signal is poor where you are, aosp may not be the best choice for you, but for most the signal is just as good as tw, and imo the only way to run android.

I'm not confused, that's why I said looks like (aka themed like). Also I said some aosp features like MMS, camera/gallery, lock screen to name a few. Its no where near the same but if they are having issues which I read a few people do have with signal and losing data its a nice alternative and has SOME similar features.

[Q] Poor wifi T959v AOKP Milestone 6, build 5

I already try to flash CM7 and CM9 mtd(KG4,KG6,KD1) modems to see if that help and nothing , always weak wifi reception.. I need help with this...What can i do to improve signal reception ?
Wifi was fine with stock rom 2.3.6
AOKP Milestone 6, build 5 is a great and fast rom but only two problems weak wifi and a little battery drain

This has been discussed a bunch.

thanks for the quick reply
Why this happens ?
its something with the kernel ? or drivers why no use original ones ?

That's a question for "Google"

Actually if you read the threads taking about this specifically the one by jeffsf he has a theory that Samsung knew many of the devices had crappy WiFi hardware and that is why the device had tons of leaked builds. They kept releasing then in hope of fixing the reception and ultimately just faked a better signal.

I saw that the big impact with wifi is make by the kernel you install, cause switching modem always the wifi signal is the same but when you change the kernel you see some diferents.

There is no super duper trick to get better wifi. What Samsung did was modify the data file to reflect a higher level. It is a visual trick and one that tricks the OS into thinking the signal is higher also so it does not disconnect as much.
What erikmm did before is change the signal bars from a actual representation to a false reading that made people think they had a better signal. Turn off the bars and use dBm readings and you will see the real signal.
This phone has a really crappy radio reception and there is not much you can do outside of what samsung did and make the signal bars read I higher rating. I think it was jeffsf that said the best solution would be to hack the wifi module and make it read all signals at a increase of 5-10 dBm so it wouldnt drop the wifi so often.

What file do i have to edit to get a fake wifi signal read and avoid disconnecting ?

I actually didn't do what eollie said to trick people I did it because of information another dev told me then I gave it a shot I saw improvements for me and thought it might improved but again if it's not you don't have to flash it or complain. Source is out do instead of complain that something isn't working or a mod isn't 100%

/sigh
Show me where I said you did it to purposely to deceive people.
Furthermore at the time you where posting those roms there was NO source code to edit.
If you are still doing that code modification then you are now purposely deceiving people.
To clarify if people think I was saying erikmm did it purposely then you are wrong. I dont know what his intentions was initially.

First off, I want to be clear, I don't know what was/is different in Erikmm/Beastmode's ROM. At the time it was released, source was not available to examine, and I haven't dug into what has since been posted. I also hypothesize that Samsung was, among other things that T-Mobile probably wanted them to change, tweaking the "calibration" of the WiFi in the various leaked releases and that the "nice" version wasn't in the final release. Considering that the "official" release modem has problems with long SMSs, it wouldn't surprise me that the low RSSI numbers reported weren't caught either. I don't work at Samsung or T-Mobile, so this is my personal speculation and opinion of a likely scenario.
I have tested WiFi pretty extensively and it is my personal belief that the RF portion of this phone just sucks; WiFi, GPS, and quite possibly Bluetooth, but nobody has complained about the last one. Unfortunately, the leaks were hosted on sites later shut down by the FBI so that getting those versions to examine as well was not possible.
If you want to "fudge" the signal levels, the details of one way to do it are in the linked thread. It will require you to create a build environment, populate it with the source of your choosing, edit WifiManager.java, and compile at least the framework. It could also be done within the kernel driver. Since I find that levels below where the current crop of ICS ROMs believe are "no bars" I don't get more than around 1 Mbps over WiFi and I do generally have decent T-Mobile signal, I just use my carrier for data when the WiFi level is low.

[Q] Signal issues with AOSP roms

i really want to stay with a AOSP rom (CM 10.2 or Illusion 4.3) but when i go to a AOSP rom i get reall bad signal (1 bar or nothing) living in chicago on verizon. When i go with a TW rom using 4.1.2 the signal is great. currently i'm using Hyperdrive RLS15 and the signal is great get 4 or 5 bars. has any one else had similar issues?

I never had that drastic of signal issues. At my house I get poor reception. (2bars max). On TW I get 2bars. On AOSP I was only getting 1. I recently flashed Latest cm10.1.3 RC2 and my signal issues have greatly increased over prior builds.
Just my 2¢
Also. I know the new AOSP ROMs require the new baseband MF1. Are you updated?

I get very bag signal at my work. I just switched to an aosp rom and I can actually send texts better than before. Instead of failing 8x, it only fails 2x. I'll take it though.
Sent from my SCH-I535 using xda app-developers app

On the 4.3 based roms there still may be some legitimate signal /data issues.
On 4.2.2 aosp ROMs the issue is mostly cosmetic, you have the same signal, but the ROM show you less bars.
Check out signal in phone status before assuming you are getting worse signal.
There are still some issues with data handoffs in aosp, but it isn't as bad as it once had been.
Sent from my SCH-I535 using xda app-developers app

Yes I'm using the latest MF1 firmware. I even reflashed the firmware and all getting bad signal with and AOSP roms. Is the something I need to do with the radio or kernel. I tried a few kernels and still same issue.
Sent from my SCH-I535 using xda app-developers app

So far every new version of AOSP has had signal problems at the very beginning. Due to that fact I usually wait until the problem fixed.

I'm on Masta's unofficial CM 10.2, and my signal is all around better than my old TW ROM (Hyperdrive RLS 14/15)
If you're responding to me, make sure to quote me so I get an immediate email.

OK so I just had access to my gf's phone. I'm running PA, she's on stock tw rooted. I had both phone side by side. Both phones read the same dmb and asu. Her phone had 3 bars mine had 1. I think its safe to say that Aosp Roms just display signal different.

status
Just an update i went to Illusion's 4.2.2 and the signal is OK, i don't get drop call like i was getting when trying a 4.3 rom. so i'm going to stay with this until they get the 4.3 bugs ironed out. It just freaks me out to see only 1 bar for signal.
do any of you guys of which rom is the closest to making the GS3 to look like a GS4?

[Q] Non-Open Source RIL/CSC for CM11?

MY QUESTIONS:
1) Is it possible to use the old Samsung RIL blob (not Replicant) with CM11? How would one go about doing that? The radios no longer include the RIL/CSC. Is there a version that does, that works with CM11?
2) Are there any ROM's that use the old/original RIL (not Replicant) while still keeping up with the latest Android versions ala CM? (Ie. KitKat)
Backstory:
Before I go barking up the wrong tree, hopefully someone with a little more knowledge can help me understand if what I would like is possible.
After upgrading to CM10.1, and ever since, I have had very poor reception (voice and data). Since moving to a new location, which should have had better reception, it has gotten bad enough that I started investigating things more deeply. The issue is that I will show 4 bars(-75-81db) then inevitably within a few minutes it would shoot down to -115, and then no service. Eventually it would come back. It was always really evident when trying to dial out too, either going into to no service from 4 bars while trying to dial, or within the first 30 seconds of a call.
It seems that with CM10.1 a new open source RIL was adopted (Replicant?). After hours of research, and trying new modems (UCMC1 & UXUMA7), old modems (and at one point thought I had lost my efs lol) that didn't work at all with 10.1+, I have found, as a few others have, that downgrading to CM10.0 dramatically improves reception (in service, instead of NO SERVICE) for those with marginal reception to begin with.
This is at home, usually with WiFi connected, so it is really about just having a working phone at home. I understand that it is possible that the WiFi might interfere with the cell service in some cases on this particular phone, but the dramatic difference (cell reception working vs not working) between CM10.0 and CM10.1+ with the same radio (UCMC1) for me leads me to believe that it CAN work with WiFi, at least.

honestly my first thought would be to ask about what carrier you have? does the issue happen on stock ROM? also I've never heard of a RIL helping aid with improving reception lol maybe you know something I don't.
The only time I've had your issue is when I'm in an LTE area with low LTE reception. My signal would jump from low LTE signal to 4 bars of H+ constantly trying to keep the weak LTE signal for some reason lol.
If that helps hit the like button!! :laugh:

Not sure what other info you would need. Currently CM10.0 works best (not perfect but usable), so I am using that. I've tried a number of different radios(UCMC1 is currently installed, but tried many others) and settings under network preferences (currently wcdma preferred is my setting). I used twrp 2.6ish up until I tried CM11, and had to revert to CWM to get that to install properly. So the latest CWM. CM kernel obviously(?).
