is it a hardware issue? software problems?
I don't know how such a problem could persist for such a long amount of time, I really hope the Nexus S doesn't have this and I would likely shell out money for that (though the lack of HD video recording disturbs me)
I have perfect GPS. After JL1, it even locks indoors in 10 seconds or less

Ever since JI6, the GPS has been able to "lock" in, but it gives terrible accuracy. It's accuracy that's important.
JK2 had choppy accuracy, JK6 made it slightly better. JL1 has been dead on for me, it even tracked my accuracy up to big bear (snow mountains in california). I went twice, once with JK2 or JK6 the first time, which sometimes listed me as off road during the trip, but when I went back with JL1, it went without a hitch.
I'm not familiar with these terms, but my accuracy has been fine, it's the speed which bugs me (takes as little as 10 seconds to as long as a whole minute before locking)
JK6? JK2? JL1? modem firmware?
Yep, modem firmware.

Same here. running Axura 2.2 JL1, i just came home from using it. dead on.
I suggest disabling the wifi option in nav setting and the sensor thing, that did keep me from locking originally.

I agree, it is unnecessary and if this doesn't help consider an exchange.
Outstanding GPS Performance After Warranty Exchange!
I recently had to get a replacement phone from Tmobile due to a problem with the haptic feedback. I received a new (not refurbed) phone in original Samsung packaging with a mfg date of 10/20/10. The phone already had JI6 installed.
Since I've had good GPS performance on my previous Vibrant I was a little concernced about what might happen on an exchange. My concerns were definitely misplaced.
The new Vibrant's GPS locks up virtually instantly, faster than my old Vibrant ever did and with higher signal strength and more birds. I've used the navigation extensively and have yet to drop connection while navigating.
My first experience with the phone's GPS was by accident. We were shopping and I needed to get around a plugged freeway on surface streets I wasn't familiar with. I went into the Navigation app, spoke my destination and was INSTANTLY provided with my location and directions. Subsequent testing has also been 100%.
I've never seen GPS performance this fast and powerful with my previous Vibrant although it worked well enough to get me from point A to point B. The previous phone on occasion would take a minute or two to find my location.

These are typically rom build / version designators. The confusion comes from using these terms to refer to the individual components (kernel, baseband / modem, etc) that have been pulled from any given rom such as the modem. When the a proper context is present, it may not be too hard to tell how the terms are being used. That's not always the case though.
blame samsung
Used out twice today locked and put in an address at a red light, it's fast, if yours isn't working try settings recommended above because it's way faster then my garmin nuvi

I am using JK6 FROYO on my vibrant, I installed it inmediatly after I got my phone with JI6, now I regreth that I don't tested my gps with it... beacuse now with froyo JK6 it's impossible to get a lock.. and the samsung fix doesn't work either
I realize now that Project Nero has JL1 already installed, so that's not it.
also, I have yet to see an answer to my question, what is the issue that causes the GPS to fail on these samsung vibrants?
If we truly knew, we would tell you. Or you would have searched and found the theory/answer(s).

JL1 was horrible for me. Constantly running on edge, and GPS sucked. Back to JK6 and everything is running great, back with strong 3G signal and GPS is acceptable (although accuracy is still off).
Best 2.1 modem JI6
Best 2.2 modem Jk6
Just my opinion

Samsung says the hardware is fine and that it is a software issue.
A few people believe it is quality control issues with the build of the vibrant (could be a loose connection and so forth)
so no one knows for sure, although most people do see changes depending on the software used, both for better and worse.
Not everyone seems to get the same results. (for some people, newer software fixes gps completely while for others it does nothing at all or makes things worse)
and then there are people that have had no real trouble from day one (they are rare, but there are some)
that's all anyone knows.
I think this question has been asked quite a few times already (there's even a few threads on this very page), you might check some of those threads for more info.

Probably multiple issues. Agps and status reporting were clearly busted originally, but that's fixed in later firmware. The accuracy issues on the other hand persist, for me anyway. Some people claim that they have no such problems, even with the exact same software, and if that's the case I can only assume sample variation in the hardware is to blame.

is best for download/upload speeds, not too worried about battery life or any of that none sense.

Don't really think you will notice a big difference no matter what radio you choose. Try them out and see which one gives you best coverage, I always stay with the latest radio, but that's me.
The official MR2 has been working great for me in all areas. I agree with the poster above tho I doubt you will notice much of a difference speed wise. I know you said you don't care but with the MR2 official when my phone is sleeping (just sitting in my pocket etc..) it uses like NO battery.

I agree with this, the BEST battery life I got was with the official MR2, i'm using the latest right now. I'm getting about 35-37 hours with the extended batt. With MR2 I was up around 45-50.
I have gotten similar performance from all of the MR2xx radios.
Hey everyone. I'm a recent Fascinate convert coming from a Droid X and CM7.
I've got CM7 on my Fascinate and am using the Glitchv13 kernel. Absolutely love the performance and battery life, however my modem/baseband seems to be a bit sketchy at times.
I'm wondering what your opinions are on the best modem for the Fascinate at this time. I'm currently using the EH03 modem.
I need reliable phone, text and data connectivity. I don't care so much about speed so much as I just need my data connection to stay up as much as possible. I've had several data dropouts on the EH03 modem already, some fix themselves while other require the airplane mode toggle or a reboot in the extreme cases.
Thanks!
I have not had any such issues with EH03... It has been rock solid.
Each person can have different results with a different modem. But as for me, I have to say EH03 has been more stable than all the others I have tried.
ec09 is the most stable withthe least amount of 1x switching. The problem is no matter what modem you have, on mtd based roms data dropping is a known issue in low signal areas. Luckily for me it was never a issue, other than having to toggle airplane mode occasionally.
Thanks for the replies, everyone.
I ended up rolling back to EC09. It seems to be more stable for me (data being solid for almost a full day now where it was dropping every few hours before).
I'm generally not in low signal areas and just about never use Wi-Fi. We have 3G everywhere so I'm not sure why I was having such awful luck with EH03.
Hopefully it keeps running smoothly. *knock on wood*
ec09 has been the most stable for me. consistent speeds and stability.
eh03 gave me lower ping times but the speed was to slow.
ed05 seems to be all over the place.
I've never switched from EC01 since it dropped (yes, before original official Froyo).
Never got caught in the missed calls stuff or anything.
I had missed calls every day with every radio I flashed until EH03. On my phone, in my service area, EH03 has been the most reliable by far!
Yeah for me its EH03 but its also the slowest of the three, but it's easily the most reliable too so I stick with it

In my expierences, Miui does not have any data drop out issues. It only seems to happen in CM7 and VGB.
Just flashed Liquid Smooth 3.2 and love it, mostly for the simplicity and the extra battery life. The only problem I'm having is the fact that cell standby and phone idle are taking up the most of my battery instead of the display like it did when I had thunderstick bareback. The phone idle makes sense but cell standby doesn't.
I've done some searching around and get mixed experiences from people using AOSP, primarily thundershed and liquid smooth roms regarding bad cell signal. Overall, however, I'm gathering that AOSP roms have terrible signal strength, thus the cell standby taking up all the battery life.
I'm thinking that if I could find a fix to this so that the radio wasn't always at between 0 and 3 bars all the time, and searching for signal, thus draining my battery, I'd be golden with battery life for days.
I've looked somewhat extensively for a solution to this, but noone seems to really address it.
BTW, I think I have the latest baseband update:1.49.00.0406w_1, 0.01.79.0331w_1
and I have imoseyon's lean kernel 6.2.1AOSP
The problem is with the ril. It was hacked up so that data and everything will even work. With thundershed I didn't get great reception or so it showed but I didn't have issues with cell idle and standby using my battery.

ok, but i would think that with an AOSP rom, and since (I think) the ril is part of the open source, it should be able to be fixed...unless the battery use is a false reading...
I don't think htc ever released the source for us on this device.

I don't remember exactly when it started, but the last month or so my WiFi signal strength had been a lot weaker on my phone. I want to say it started when I started using ASOP roms, but even back in a sense Rom now, I can't hold a signal even one room away. It's not my router because other phones/laptops still get a good signal.
Any ideas on potential fixes to improve signal strength? I'm s-off and on Ineff Deus 1.2 at the moment. Tried different kernels with the same results.
Not much I can say, I get better wifi reception on CM9. Holds out way more than it did on senseless ROMs.
Wipe and reflash?
Already clean flashed a couple roms. Doesn't help. Now I'm just on LTE all the time, so not a huge issue, but of course battery drain is much higher.
Did you recently replace the battery cover or have it off a lot ? The contacts could be funky for the antenna..
