GPS on the Fascinate
I spent lots of time testing the Fascinate's GPS and unfortunately, performance was just as bad as I've heard it being on the other Galaxy S phones. It's really the entire line of device's achilles heel.
There are two real issues with the GPS - fix speed, and overall low SNR. I'll start with Fix speed.
I've seen the Fascinate get fast GPS fixes, and then 10 minutes later get extremely slow fixes. It's completely erratic, and there's no predictability to it. Right out of the box, I timed a whopping five minutes (even connected to WiFi) standing in my yard with a huge swath of visible sky.
Other times, the Fascinate gets GPS fixes quickly like any other modern smartphone - within seconds. At one point, I proclaimed to Anand that I was certain I had fixed the issue by disabling Verizon's location services - all my fixes that day took seconds. As we iChatted for the Apple 27" Cinema Display review, I tried to demonstrate my great success - and of course those fast fixes suddenly stopped. It seriously hasn't been fast since.
The other problem is fundamentally low SNR. Look at this shot, and guess which one the Fascinate is:
That's outside at night in a completely empty field with ideal sky visibility - no clouds, no rain, just cold air. Look at how many satellites the Fasciate has compared to an EVO 4G (right) and Nexus One (left).
Repeat the same thing in my office under a foot from a huge window:
This is the case indoors, outdoors, in the rain, daytime, nighttime, it doesn't matter - GPS is just poor on the Fascinate. The device is almost always at least 1 or more acquired satellites fewer, with slightly worse SNR being reported. It's small consolation that at least on Android we can have apps which read NMEA data so we can diagnose exactly what's going on.
Slow GPS fix times can probably be fixed with a software update. I've read differing reports that the Fascinate already has this fix applied - I can only hope the device I had didn't have it. Poor SNR and signal strength, however, is a problem no more fixable on the Fascinate and other Galaxy S phones than it is on the iPhone 4 - unless of course it's being reported incorrectly by the GPS receiver. I believe that GPS accuracy on the Fascinate isn't really as much of a concern when it takes minutes to get a GPS lock. Anything is better than nothing.
Until the GPS issues are fixed, using things like Google Navigation are downright frustrating. I've literally gone driving with the Fascinate, attempted to use Navigation, only to finally get a GPS lock after I'm 3/4ths of the way there and already looked it up on another smartphone-in-test I've got with me. It's frustrating and maddening to say the least.

Chemist1,I actually completely agree with you, 100%. When I joined on to tackle smartphones, my big objective has and still is to nail down testing for everything that's traditionally been subjective - battery life, screen quality, performance, signal strength, e.t.c, and make it just as objective as hardware reviews. Of course, audio (voice) quality is on that list as well.
I've been grappling for some time on an ideal test methodology, one that would give a much better (objective) means of testing actual call quality than - it sounded good. I honestly couldn't agree more that this level of analysis is lacking. Unfortunately, until I've got that nailed down, it's really all I can say. What shape that takes is still up in the air.
I've thought of recording the local ASOS weather station test call (which is so far what I use for measuring speakerphone volume) through both the line-out and speaker, then letting people compare those audio files directly. I've considered using some spectral analysis tools similar to determine the pass bandwidth of these phones (of course this would require some tweaking due to cellular latency and also a land line), and a few other things. If you or other commenters have suggestions, I'm more than all ears, seriously ;)
I've actually done a fair amount of playing with CDMA voice codecs in the past - a number of WinMo devices would let you change from relatively-basic EVRC to better 13k voice codecs and a number of others. That kind of discussion and reporting about what codecs each device are using is where I'd like to go, getting that from Android sometimes is very difficult unfortunately. In fact, only device I've really seen that on so far is the EVO. I'd also like to eventually be able to characterize the difference between 1x voice, GSM and UMTS.
There's a lot more we're trying to add for certain, I/we just have to figure out what the best way of testing those would be.

You may find this shocking but I highly doubt people will consider audio quality as important as you do when deciding for a smartphone.I faintly remember some study on what consumers are looking for in portable audio/MP3 players. Audio quality was NOT in people's top 5! Design, storage capacity, and three other things I cannot recall right now were more important to them. In an audio device!!
So there you go.

jasperjones: Thanks for your comment. Well, one needs to be careful of these surveys, since small differences in wording can significantly change the outcome. But your point is well-taken: audio quality is not a top priority for consumers. Nevertheless, that's not to say that audio quality is of no interest to the majority of consumers, nor that it should not therefore be of significant interest to us. [Please see paragraphs 2 and 3 of my reply to kmmanety.]MacTheSpoon - Wednesday, October 6, 2010 - link
Audio quality matters to me, too, thanks for fighting the good fight, chemist1. ;)By the way, I own the phone and I have found the audio to be pretty good for calls so far. At least, I haven't found myself wishing the phone was louder or had any problems distinguishing speech.
Listening to music with headphones...I don't have golden ears, and I don't know how it stacks up to a top mp3 player like a Cowon, but it's definitely not a low-end sound like my iPod Nano 4th Gen or my 2007 Macbook Pro, anyway.

Kinda like how in CNET reviews of point and shoot cameras image quality only accounts for something like 10% of their final score.Though a lot of consumers probably just assume audio quality is good enough. The majority are going to put compressed music on there anyway and then use cheap earbuds, so a lot of the audio quality discussion that goes on on tech sites is utterly irrelevant to the majority.

In addition to measurements of sound quality, how about a simple internal poll? Record sound samples of various phones, post them with obfuscated names for other staff members to listen to and have them judge intelligibility, clarity, harshness, etc. This should give you a decent sampling of real people's observations. Better than just your own.dagamer34 - Tuesday, October 5, 2010 - link
Brian, there are some JPEG artifacts in your gallery shots. I doubt the D80 has such visible artifacts on a downrezzed shot.Brian Klug - Tuesday, October 5, 2010 - link
Yeah unfortunately the gallery preview images are compressed even though I upload originals from all the cameras. If you click "View original size" you'll get the raw untampered JPEG though, complete with all the EXIF headers and everything you'd get from the camera. Unfortunately I can't control how the engine compresses those images for the gallery preview.-Brian

One problem is that the Audio quality changes so much with various factors (signal quality, the phone at the other end, etc..).I would disagree that that the main purpose of these phones is to actually be a "phone". No one cares that much about call quality when they are buying these phones - you just assume it will be acceptable.
softdrinkviking - Tuesday, October 5, 2010 - link
Brian, even though there are many factors, I think you can do an, "all things being equal" type of test with a couple of variations.The data will still be meaningful when you are comparing it to other specific phones.
