I've noticed when going from TW roms to AOSP roms that the service signal is dramatically lower. I can be running a TW based rom and have 4 bars of signal but then when I switch to an AOSP rom the signal indicator is at like 1 bar.
Why is that?
Any explanations are greatly appreciated. :good:

It's not less signal per-say but it's the way it's reported. Aosp reports it correctly where as tw it's exaggerated

Oh really. So if I go into settings and check the status where it displays signal strength would it be similar there? Or does that differentiate between the two types as well versus the visual signal strength in the status bar?
I appreciate the response.

I highly disagree with you. I can't stream any videos with AOSP without videos freezing and needing extra time to buffer. Touch wiz does in fact have a better signal because I've flashed back and forth enough to make that confirmation.
And that's in the same spot. Aosp in fact does not have better signal.

Go into settings and look at the reported dBm for the signal strength and see what it is, then compare it to the reading in the same location on TouchWiz. You would need to do this as close to the same time as possible to limit as much variability in the signal as possible. You can't trust the signal bars, they could be set to show you full service when you have none if one really wanted to.

I actually disproved my initial issue with this now.
I have been running Jelly Beans BLD 12. The signal strength was -98 to -100 dbm 40 ASU LTE:14
I just flashed the new release of Liquid Smooth V2.1.. The signal strength is -99 dbm 40 ASU LTE
This is the first time i've flashed between the 2 types TW and AOSP and have had the signal strength both in the settings status and displayed on the status bar.

How can that happen when the radio's are the same? All your flashing is a rom, and a rom CAN NOT change your signal strength.

You may get a slightly different signal strength, but it wouldn't be significant, only a few dBm. The RIL related java items are different between TW and AOSP, and there may be a slightly different modem driver in AOSP based ROMs as well, both of which could slightly affect signal, but again, nothing significant. I'd guess you'd have a 5 dBm change at most, which isn't something you could really even say is ROM related, as signal could vary that much just moving your phone 5 feet.

I have the same exact issue. This is not a reporting issue. Where there is low signal on TW, there is NO signal on AOSP. In regular or great signal areas on TW, there is acceptable or great reception on AOSP.

I must agree with you, before the sbrissen started trying to fix the RIL it was better but not by much. I am missing calls and texts left and right, to the point I am going to have to go back to TW.
I can't wait until everything gets worked out with the RIL though. I would rather run AOSP with the PA mods built in instead of them being hacked into a TW rom, its just better all around and much easier to deal with. This phone doesn't look right running in phone mode, it needs to run in phablet at least to look good!

i dont understand what RIL is. But i do use my phone a lot, at home and work. I notice signal strength weakened with AOSP roms not doubt about it. I don't even need to flash back and forth to notice or check the dbm or whatever. Spots that are usually weak inside buildings i wont have any at all. It cuts out often. like no signal at all. its unfortunate because i was starting to like stock android. You'd think there be a port from the google edition S4

im losing service all the time
when my phone is sitting there it says 1 bar and 3G
but when i try to use anything that uses internet its cuts off and loses service,
then goes back and says 3bars and using 1x, which works.
So basically it wont connect to 3G and says it only has 1 bar when my sisters works n 3G and says she has 3bars. and when i tether its extra slow since its running off 1x, and it loses service randomly while surfing internet, or texting, or when making a call. but when im on the phone the service never cuts out and shows 3bars
any ideas?
ps happends with EVERY rom
update prl?
Every ROM at any location?

The radios are a bit of a finnicky thing. Some people love the newest and some love the original.
Location is the most important factor when dealing with reception. You can try all the different radios and see which works best for you. There are threads on these forums with all the different radios attached.
*FYI - Be very careful when flashing radios as you could brick your phone if done improperly.

That is the latest radio, but as I said before some people swear that the older ones work better for them. It doesn't hurt to try others and see if anything improves for you. Here is a link to the radio thread.

If you're not getting good signal reception it could be your rom like someone mentioned. Some roms have signal bugs ive heard. Do you normally get reception and good signal strength when this happens? I see you updated your prl, but one thing that worked better for me was flashing the verizon/alltel hybrid prl. Gives me a much better signal, but some people have reported opposite effects. Cant search too well with tapatalk so I cant give you the link but its on here somewhere.

I'm running Tazz Vanilla v22 right now and Toggle2G don't work with this ROM. Any suggestions? Also the signal bars seem inaccurate in 3G mode but I notice it seems like it's more accurate in 1x.

I recall investigating this inability on our phones and if I recall correctly, you can only switch to 2G mode on GSM phones, not CDMA phones like this.
Anyone correct me if I'm wrong or there's more to it than this.
I know you're often an answer man, though, so perhaps you know something about this that I don't. I know I've tried switching to 2G before and I couldn't on various ROMs.
I noticed E2 is way faster. BUT big but, E2 has way worse reception.
Am i the only one?
I was on Jersey Shore today and I couldn't get any data working.
If that is the case for you, then you could flash a different modem I suppose.

I've noticed way faster data speeds on E2. I used to see about 2 down, now I see about 6 down. And I've had no signal issues, always 4 or 5 bars. Afaik, different modems can give vastly different performance for different people. All depends on your area and what not. Just experiment with the various modems. I'm just glad Samsung finally got one right for my area, as I've only ever seen about 3 down on any phone I've owned until now.

The AT&T version of both of those modems, which is all us Canadians have access to thus far, has, for me, had much worse data speed numbers (non LTE anyway) on the Telus network than the stock GB Telus modem.
The E2 modem is, in my very non scientific testing, slightly slower for us here in Canada. (again, HSPA only, no LTE coverage here yet)
I'd really be interested in understanding what is actually different between carrier modem implementations. I noticed a similar speed differential in the stock modems.
I tried adjusting the RF preferences but that doesn't solve it. Its almost like AT&T doesn't have the same implementation of HSPA+ as the Canadian carriers.
I say all that with some degree of confidence in the numbers... having installed a variety of ROMs n modems and the results from the stock Telus modem are consistently better when I can use it.
Currently on the One Beta and associated LE2 modem, it shows very wonky "bars" by times...like none, in what should be solid five bar area.
My fourth floor office which never wavered from five bars on stock.. Consistently now shows any where from 0 to 3... But it still transmits and receives calls and data.
A buddy of mine is testing the Telus 4.0 release with Premium Suite... so in any event, it shouldn't be too much longer.

is it really that much faster? ive yet to upgrade from UCLD3 because its just running fine, wanted the next time i update my phone to be the last (offical ICS since i doubt we will get a update any time soon after that)
I noticed a big difference in speed. UCLD3 used to stutter a lot and freeze up from time to time for no apparent reason. Haven't had any of those issues with UCLE2. Also, bugs that annoyed me in UCLD3 were fixed in UCLE2. I don't see any reason not to flash UCLE2.
I've been having a bug on ucle2 where I cant keep a wifi connection for in app downloads resulting in the download stopping I've tested on multiple ucle2 roms and confirmed no issue on ucld3 not sure how I got so special because I haven't seen anyone else report this that I know of

Can someone explain to me why on TW roms you have a better signal strength than when on AOSP. I am not sure if its just my phone or what. Example on TW rom it goes between 3 bars on 3G and 1 on 4G ( not completely 4G in my area yet). But on AOSP I have no bars on either , and I end up missing calls . Is it something I can do or am I just out of luck

Samsung has the proprietary drivers for cell signal. The RIL for CM Roms cannot obtain the same level of signal. I've compared this countless times with CM vs TW, and TW will always have the better signal/data strength. This is especially pronounced in areas of weaker signal. You'll notice that you'll drop LTE, and it will take a while to get it back. It has been much improved, but if signal is a must for you, TW cannot be beaten. Sometimes you can compare the dbm side by side and it will show the same, but real world use will have AOSP roms suffering more with their signal. Sucks, but it is what it is. I used to always flash aosp for speed and then signal issues would annoy me (work in buildings with poor service to start) and would end up on TW again. Ymmv

Understandable and thanks for replying back but I am still a little bit confused. This almost means that everybody who is on CM roms have only a 3G signal at best. And from what I have been researching TW roms pretty much do not exist anymore (or at least are not updated) I am just having a difficult time finding a rom that has everything I want as well as my LTE/4G data speeds. I have tried over 10 different nightly PacRom builds and its the same thing. If I mess around with the different "preferred network types I can get it to trigger LTE but then I am unable to make or receive calls. I would post this in the PacRom thread but I do not have enough posts to do so.
Thanks again for replying back.

Do you get full 4G when you're on a TW rom? I run nephilim right now after trying all the roms and I think it works quite well. Theres no perfect rom out there, so you'll have to decide what you're willing to sacrifice
What I noticed on AOSP/CM/AOKP roms:
Battery life is dismal - even on airplane mode I drained my battery to 20 in 6 hours.
GPS performance is lowered - even though I get locked on, it doesnt seem to track me as well. (this could be coincidental or biased.. lol)
Signal - definitely lowered, but barely not very noticeable. (You might want to check on a TW rom like I mentioned earlier)
Camera - some roms are super buggy, crashing every other shot then unable to initialize my camera afterwards
Text reflow is gone
Random bugs all around, usually not bad if I'm working in the office, but for weekend excursions, I'd rather have the stability of TW overall.
Let me know what you think, and definitely try switching back to a TW rom to see if your signal woes are resolved. Could be a hardware issue as well.

I tried Trent's and nephillim ROMs and I still have only 3g on both. This has just started happening recently too but it stays on 3g no matter how many times I wipe data and factory reset. Im starting to think that I may need a new sim card. Also I didn't realize the WiFi issue with the other two 4.3 ROMs until I already flashed them and then reverted back to 4.4
Thanks again for the assistance. I'm gonna get a new late sim card and see if that helps.
