I am beginning to lose my cool when it comes to reception and my Captivate.
At work I used to watch a lot of youtube on my Tilt2 and altough it some times went on a wont connect spree....most of the times youtube was a no problem.
Unfortunately the Captivate is like almost never connects or just a little bit and once again loses it.
Is this about the whole hspa thing?
Even at home when reception is better for both, South Park is a lagfest with the Captivate if I use 3G unlike the Tilt2 but then again that could also be Skyfire....in any case...is this normal?
I guess you have never used and iPhone???
I had an iPhone 3GS and it was a POS when it came to reception.
I'm sooooooo happy I'm finally able to have an android phone on AT&T.
It takes some getting use to compared to the iPhone. Just basic navigating through the phone is very different.
I don't mind dealing with some minor flaws of the Galaxy S because I know for sure this phone will be improved because it was released on all four major carriers, not to mention it was already out as the GT i9000.
anyway - just my thoughts
sorry - I know this didn't answer your questions but wanted to share
Never had an iphone and never will! lol
Its just that I love this phone so much that I just cant stand it that reception is hurting me this badly...I just need to be patient I guess.
Like on the weekend... instead of streaming a soccer game to my Android I had to ask my wife for the Tilt2 again to watch the game with some friends at the park...
No. My tilt2 got sligltly better reception too. It OK I love my captivate.

Man, you guys are killing me. I have a Tilt 2 with Energy ROM and for the most part I'm happy with it, but I'm just dying to upgrade to a Captivate, but I keep hearing about reception problems. On the other hand, if you Google any phone these days you hear about reception problems. If you guys are saying the reception is worse than my Tilt 2 I'm just not sure I can live with that though. I frequently work on drilling rigs where reception is pretty bad to non existent. I'm thinking about just swapping out my Tilt 2 for a new one since the keyboard is wearing out, but for $125 deductible, an upgrade sounds pretty good.
Reception is the same or better from my original Tilt.

I would upgrade if I were you.
As much as I liked my Tilt2 there is no way I would go back to it after being using the Captivate. The speed difference is just too much.
So much that I have gone from fancy Energy Roms on my wife's now tilt 2 to the simplest and fastest 2.1 ROMS I can get so it does not feel too slow.
Tilt2 has had numerous radio upgrades you can install since it came out
I would imagine when samsung releases some radio revisions we will have better luck with reception.
I really have not noticed the Captivate having significantly less reception than the tilt2. Now for battery low on the other hand.....
For me the difference is obvious even on stock tilt 2 radio.
For example watching you tube at work with my tilt 2 it was almost always a non issue but with my Captivate I get several disconnections and most of the times I have to go to low quality mode to get a decent experience.
Still, no way I am going back to the Tilt2 ...wish I they could finally get android running on it...that would make it a much nicer phone I think
I dunno, I've had noticeably worse reception on my captivate than my old blackberrt 8310

See, this doesnt make sense to me. After all it is a PHONE first, everything else second. So you're willing to sacrifice reception ability for speed of user interface, etc? Why? In your post you were just complaining about how poor the captivate's reception is vs. the tilt 2, yet you'd recommend the captivate because it has a faster CPU or slicker UI than the tilt2? Why not just carry two phones, one to actually use as a phone and one as a toy? That makes about as much sense to me. JMO.

Ok first I think someone forgot his pills this morning
First reception not extremely poor compared to the tilt2 just youtube freezes more often at work which is a hard place for every phone for some reason. The Tilt2 was better but I did had to switch radios from time to time like something will change then a new radio will do better for this month or so.
Second, this is only for video watching...phone calls I have zero issues in quality or connectivity so far...yes it is a phone so that IS the main reason to have it.
The main issue has been Skyfire but I got confirmation from the developer that this is indeed a matter of Skyfire on the Android not being quite up to par yet to the Windows version but they are of course working on it.
So, today for example, I have been connecting to the market and downloading stuff and even watching youtube quite smoothly.
So in my first post I gave the impression it was a huge difference it was based on SouthPark and Skyfire.
So if you are able to calm down a bit feel free to rejoin the conversation but if you are going to go off like that then by all means, there are more threads around.

Well I'm glad I found this thread. When first hearing about the Captivate I was not very interested due to concerns about the Samsung interface, reception issues and GPS issues. I was also really hoping for a 4.3" screen and possibly front facing camera and a flash.
Now after reading that the GPU is top notch, GPS issue is fixed, or will be soon, and reception is generally fine I'm very much leaning toward the Captivate. Samsung interface seems to be not as bad as I initially though, and the speed is plenty fast enough even without froyo. Also NewEgg has them for $79 with a contract renewal.
I have to say I really love the new MaxSense ROM's from Energy though. I hope I can make Android look that good once I take the plunge. I'm still worried about the lack of hardware keyboard too, mostly the fact that it covers half the screen when using it.
For what it's worth:
I've owned a Tilt2 for 3 months, tried out pretty much all the available radios, and have a pretty good judgement of it's reception. I've also owned a Tilt (Kaiser) for almost 2 years.
My Captivate gets much better reception than either phone: I get solid HSDPA reception in places where neither my Tilt/Tilt2 could. The trick is to just ignore the signal bar. I live in an area with poor reception, even after the 850 MHz upgrade, and at times my phone shows no bars, but gets good quality voice/data reception. So don't rate your impressions of signal quality based on the on-screen display, only how the device actually performs.
And as far as GPS goes, I've head-to-head compared it against my Tilt2 (which has a pretty decent GPS) and the hardware itself is more sensitive, and sees 3-4 satellites indoors in places my Tilt2 can't. There are definitely weird and inconsistent problems getting/holding a lock, but to me it feels like a kernel or other software issue. So hopefully a solution can be found (by Samsung or Devs).

Thanks for the input. That's good to hear considering I'm fairly happy with the reception on my Tilt2. I have to say the GPS is inconsistent though. Sometimes it won't even pick up outside. I'm thinking about heading to Best Buy this weekend to pick up the Captivate and give it a try. I'm really looking forward to the improved video performance, bigger screen, and a standard headphone jack.

Oh no, my impressions were not based on bars...in fact, you will see not a single comment about those I think. That is irrelevant to me.
Although as I mentioned on my previous post, without considering the differences between the Skyfire performance, the difference is not that big.
How are you getting HSDPA on that phone, I thought the hack was not working for ATT?

If reception is primary concern I hear the Jitterbug gets good reception?
Seriously there has been a slightly weaker signal for me but we are talking less than 10%.
P.S. map your coverage if AT&T gets bad enough coverage maps from real use they will have to fix their coverage.
My reception has been great with my Captivate, it drops less calls than my iPones and Nexus One did....my Blackberry Bold is still the king though (always had great reception with it, and battery life was insane). I do however have issues with AT&T's network in the DC/Baltimore area...theres just so many people using data that everything I do lags and takes twice as long, and I've almost never been able to watch Youtube videos in Hi-Def while on 3G...on ANY of my phones while in a populated area, but it works fine at my parents house and when connected to our 3G microcell at home. I think the Captivate works great as a phone and the 4" screen seems like it sits right in the middle of being too large and too small, meaning its perfect for me. I owned a Tilt2 and couldn't stand it after owning iPhones and the Sprint Hero...I loved the keyboard but signal strength and the browser killed it for me, it only lasted 2 weeks before it went back. Give me the Tilt2 form factor with the Captivates screen and guts on AT&T and it'll be my next phone lol.

As I understand, it's HSUPA (uplink) not HSDPA (downlink) that's the problem. Without HSDPA, we'd all be getting download speeds of less than 1 Mbit/s. And since the hardware supports it, it's only a matter of time before someone releases a working HSUPA radio.
It really is a great phone though. And for me, the biggest deal-breaker over the iPhone4 (and most other phones) is that I can simply drag-and-drop video files from my computer to my phone. From simple Xvid/Divx/OtherAVI files, to 720p HD MKV files. No transcoding, or other work required.
Don't buy it expecting it to be flawless though, the underlying hardware may be, but without XDA and the community to fix the software flaws, it wouldn't be nearly as appealing a phone.
Well I found a guy selling a Captivate on eBay for $400. My contract isn't due for an upgrade yet so I figured what the hell, if they come out with something amazing next year I could use my upgrade then. I'm definitely looking forward to the h264 decoding and "5.1" sound. I just hope I can find some widgets to make the interface look as awesome as my Energy MaxSense ROM on my Tilt2.
I just upgraded to the captivate about a week and a half ago so I could return it and get the Inspire when it's released if I wanted. I've been looking everywhere trying to compare the two and just can't make up my mind. So, what are some pros and cons of both?
Captivate-
Pros:
AMOLED Screen (4" screen is a pro for me)
Battery Life
Great Dev support already
Thin
Good Camera
Cons:
GPS not as accurate as I'd like
Samsung & AT&T aren't supporting it very well.
Inspire-
Pros:
HTC build quality
HTC Sense
Better Camera
4G Speeds (although my captivate has some amazing speeds with different modems)
Most likely better support
GPS
Cons-
Large non AMOLED screen
Thick
Poor battery life
Kind of a last generation phone (HTC desire HD) with added 4g speeds
I think it will come down to being able to see the two phones side by side once the Inspire 4G actually comes out next Sunday. I also am looking at it, because I've always liked HTC in terms of build quality and HTC Sense, but at the same time my Captivate is a more than capable phone. Sure HSPA+ would be nice, but it's not in my area yet, so I don't really have that to worry about at the moment. I plan on seeing how it performs against the captivate once it's actually out, and then deciding whether I want to buy it or not. I suppose I could lobby for it for a late birthday present, it is 3 days after my bday I'm not going to use an upgrade until AT&T has LTE phones available though, that would be purchased retail.
Because I don't even use data, it doesn't even matter whether it's 4G or not; I just use my Wi-fi.
I think what it's really boiling down for me is just the great quality HTC builds their phones with, plus the fact that Cyanogenmod is already being developed for it.
While my Captivate has been nice for the past month and a half, I'm going to have to ring ATT Warranty ASAP and get the Inspire from them, tell them about my shutdown issues [I had a refurb Captivate to begin with], so they'll have to exchange it for me.
I'm not even going to wait for Atrix or Infuse, not worth it.
How will you get an inspire?

I'm wondering this myself. I know that with Verizon if you have a phone replaced 3 times they will give you a different phone of equal or lesser value, but won't they just replace it for a captivate that doesnt have the shut down issues? I don't see how they would just upgrade you for free....
At&T has already stated that they will not be offering me phone models to those who have had the shutdown issue. This is not to say that some nobody will convince them othwise bit the policy of offering a new model after three replacements has already met resistence from at&T even before people have had the opportunity to try.

It's not an 'upgrade' technically... ATT warranty will make you switch out the phone twice. The third time you call in, they'll probably be reluctant to give you a different make and model, but you have to insist. If that doesn't work, have them transfer you to either a floor manager [they walk around and have administrative rights], a supervisor [not always as effective], or the Resolutions team, which is just a group of administrators that are sometimes really helpful when you're trying to do this.
Obviously you'll have to wait until they actually have refurb Inspires, you're not going to walk in there on launch day and ask them for a refurb... You have to make it as if you aren't obviously looking to get a better phone. What I usually tell them is that the phone has [insert problem here], and once they send me the second phone, I'll check the IMEI, make sure it's in the affected range of IMEIs, and then report it again. By then, you can say something like you went to an ATT RETAIL store, and they told you to call in about this phone that is very similar called the Inspire. When they ask you why you didn't just replace it there, tell them that RETAIL STORES DO NOT OFFER RECONDITIONED PHONES.
By now, they've run out of luck and will process the order for you.
Cheers!
The AMOLED screen sucks. Big time. Text is grainy. Solid colors and gradients look oily/rainbowy. Everything is oversaturated.
im thinking about switching to the Inspire or Atrix (Inspire just got more interesting as I dont like the pricing policiy on the Atrix).
I have had the Captivate for a couple of months now. Nothing wrong with it per se, it des everything its meant to, but I spend my time trying to make it have the look and feel of Sense!
Captivate has a great camera (better pictures than any HTC device I have ever used, and I have had many) and a bigger battery. Screen is very good, but I like bigger screens.
so Im going back and forth. Is there really anything that much better on the Inspire?
I sent back an aria 3 times and they sent me a captivated. So they will upgrade you

I was offered a free upgrade to a new inspire after my third captivate failed. I had to really fight for it, but after an ATT rep suggested I find a new phone on EBay, I was mad enough to ask for his supervisor. That did it. Problem solved. I really did want to stay with ATT because our whole extended family is with them, so I asked them to please help keep us from switching. I love the inspire - except for the lack of swype. I miss that feature

build quality? really have you ever looked inside one of those things? what makes you think it is built better?
The pros a cons from comparing both side by side.
Inspire :
Pros :
Big screen
Great ui
Decent GPS
Great feel
Cons :
Considerably slower than captivate
Horrid battery life(carry your charger)
Confusing settings and menus
Even with sense eventually you're going to flash another ui (on to other things)
Terrible build quality
Captivate:
Pros:
Awesome bright and clear screen(better than the atrix by far)
Good battery life(up to three days)
Thin
Swype
Great community support
Great build quality
Cons:
Terrible GPS unless the sky is clear on all roms
Can drain a battery fast(its powerful)
Kind of small
Now notice how I didn't list support as a pro for either. THE SUPPORT FOR BOTH PHONES IS THROUGH ATT AND SUCKS ASS. Contacting HTC only got me sent to att and it sucked. Just getting a battery rma was a pain.
Now if you want to go for android get the inspire. Its built for android. If you don't mind waiting for gingerbread and spruce then get the captivate. We love our terrible GPS for a reason. Its better all around.

Can I ask where you live? Ussually some places have better GPS than others(Texas and new York being the best due to building mounted GPS towers).

orange county new york. not anywhere near nyc, actually nyc can cause issues with the tall buildings but i can navigate there decently now. i have driven down to philly and dc without issues and up to buffalo. i really dont think it is a regonal thing
it wasn't always that way. jf6 and jh2-3 roms needed a clear sky.
ji6 would crash the gps if i changed settings causing it to fail to start gps untill i preformed a factory reset, simply reverting settings i changed and clearing gps data did not help. (the samsung app also corrected this situation without reverting any settings)
jj4 was the first rom i was able to use the gps without looking at the weather or being carefull about what i did with the gps settings.
with da_g's fix it did not crash like i described above on ji6 based roms.
but now after trying several modems and gps settings i find that there are several good modems. kc1 is my new favorite. kp1 seems to work good on some roms and act erratically on others. jl3 works good for gps as does jk3-4 but jl3 is better than the jk3-4 modems by a small amount. none of those modems are as good in call quality as kp1 and kc1. there may be others that are good.
also ms based modes can cause random blue circles and incoming calls cause loss of gps signal. i think it is an interference problem. but running gps in standalone mode with a kc1 modem and da_g gps fix for good measure gives me the best gps i have ever had on a phone(provided i dont get incoming calls)
The incoming call problem you describe is because the phone a GPS share a chip causing interference. Anyways thank you for the information. Always interesting to see how people fix it. And KB and kc modems have the audience chop so it sounds awesome. Buy it only works with KB and kc kernels as well otherwise you don't get that awesome chip. Anyways thread Jack over.

I had the captivate and switched to inspire and have liked the inspire so much more since day 1. Sense is a great user interface and runs smoother than touchwiz. there are ways that you can make the battery last longer as well ie juice defender and such. It has a flash for the camera which for whatever reason was lacking from the captivate. The captivate had terrible support from ATT and samsung and i broke two of them in a matter of months. First one the speaker broke second one the power button broke i am not buying a samsung phone ever again because of the captivate
Every once in a while I see people claming a certain modem works best in their area, is this an actual phenomenon or just claims? If it is something that can be agreed on, I think it would be great to have one place to see what modems seem to work best by locations.
Me personally I haven't done much modem testing. I'm using JL2 in Augusta, GA and it seems to be working well. I haven't found a modem that doesn't work here but I probably don't know the best ways to test this out.
I also like to see the location when people are talking modems. Im in the detroit area and have the best results with KP1 on my phone. My download speed is supersonic compared to stock. I have tried at least 4 others but none perform as good as this one here.

Good coverage area kicks up to 500kps.
Voice quality a tad quiet.
No worries for me, I hate the damn phone. My cappy is my tiny pc.
Booyakasha..........What did I just say?
KP1 in NE Florida. Using it gives me signal in place that I couldn't get it with the stock modem. Areas where I got signal previously are stronger than ever and data is much, much faster.
you can try jl2, jk4, kp1, that is enough ...
I have not tested modems extensively here in Houston, TX, having only used (not tested or benchmarked) KP1, JK4, JL3, whatever shipped with Cognition, and whatever was with stock 2.1.
I have had by far the most time with KP1. Incoming voice quality is good, but the main attraction is the data speed. At home I've broken 3100 kbps down and 2600 kbps up. I barely broke half that download speed previously.
I can't comment on reception, as it's been pretty consistent across all modems I've used. Houston is pretty well saturated with AT&T signal, at least the areas of town I frequent.

My SGS has Poor Signal reception in Most areas where, Other Phones have around 3-4 bars. On my SGS Calls drop, and sometimes, It says No Service as well. This happens in Areas which are far from a cellular tower.
I use 3G, and even switching to GSM only doesnt help in most cases.
Anything I should try :?
Using In Sri Lanka, Dialog GSM. Using JVR, with JVO Modem. Tried the ZSJPG Modem as well, same problem.
flash JVT baseband. It drains battery little more but has better signal. From my experience.

yeah I think I noticed a bit of a difference on onecosmic's ICS port here in aus
Thanks heaps for the replies guys,
But ICS Port is still a wip isnt it ?
I'd wait till it completes and comes out of the testing stages.
Also, I think that this might be a hardware issue as well, so thinking of
taking the phone apart, and replacing the antenna material with something more sensitive / conductive.
Lets see how it goes..
You could try the 3g tweak script from thunderbolt, worth a try!

Thanks Guys, I just sold the damned Phone. It was a headache.
What's the use of it If i cant make calls at home.
Thanks folks !
Hey guys yesterday i upgrade to 4g sim card and got 4g signal for the first time in my life lol. However after using for a few minutes using phone i start to feel nausea tired dizzy. Dont kniw why. I guess the reason is the signal from the phone is too strong. My tel service provider use 1800mhz band. Does anyone experience similar issues or is it just my imagination lol
Probably just your imagination! Lol. The SAR values of these phones are within the acceptable levels and aren't harmful in majority of cases. People who set these guidelines and standards go through a lot of research so that we end consumers don't have to. So it is safe to say that it is just your imagination that 4G is the cause. Your mind is just trying to associate two different events; getting 4G for the first time and a random episode of fatigue or a headache. Considering you also mention that 4G signal is quite strong in your area, your phone only requires very less power to lock to the network, meaning very low or negligible radiation.
But it would be best to visit a doctor who may be able to help you with the symptoms.
