The Display: Like AMOLED, but Super
Did I mention Samsung also makes displays? The Epic 4G and the rest of the Galaxy S line are among the first to use a new type of active matrix OLED called Super AMOLED. The main difference appears to be that the capacitive touch layer and AMOLED are now integrated rather than laying on top of one another. This sounds a lot like the manufacturing technique used in Apple’s Retina Display. It’s supposed to reduce unwanted glare/reflections and improve the efficiency of the display.
The end result is very noticeable. The Epic 4G is much easier to read outdoors compared to the original AMOLED Android phones like the Nexus One:

The Super AMOLED display is a nice improvement over the standard AMOLED. I’d even go as far as to say that it’s comparable to most LCDs in direct sunlight, at least when you’re looking at things that aren’t white. Displaying white is a problem for AMOLED screens, it eats up a ton of power since the technology is emissive without the use of a backlight.

The biggest selling point of AMOLED is its deep blacks, which the Epic 4G’s display delivers perfectly. The display is almost too contrasty. The bright blue text on black background in the settings pages just pops.
Brightness is an issue with the display. The brightest white I measured was only 300 nits:
Samsung gets away with a relatively dim device by having perfect black levels, but the display’s weakness is visible when reading web pages with mostly white backgrounds.

In the photo above, the Nexus One looks brighter, but the Epic 4G's white levels measure higher. I suspect this may be a Super AMOLED vs. AMOLED issue with our x-rite colorimeter. In practice the Nexus One has brighter pure whites while the Epic 4G has a brighter display in any other situation (e.g. home screen).
As AdamPflug correctly pointed out, the Epic 4G's web browser has a separate brightness setting which explains the difference in brightness above in the browser. In this case the brightness was set to around 20% of maximum on the Epic 4G.
Samsung includes a dynamic display feature that reduces brightness depending on the contents of the screen (there’s also the standard auto brightness based on ambient light). It’s not that noticeable when turned on in most situations but it reduces maximum brightness by about 100 nits. Again, this is mostly an issue with web pages that have a lot of white in them.
I’d say Samsung’s Super AMOLED is in the running for best display on a smartphone up there with the iPhone 4’s Retina Display. Apple has the resolution advantage, but Samsung has a huge contrast advantage. The former is nicer for reading text, while the latter is better for just about everything else.
Even if you don’t get the Epic 4G, Super AMOLED displays are where it’s at. They’re far more usable outdoors and you still get the contrast benefits of AMOLED.

I bet it has to do with the 4G/WiFi-MAX radio. I have a Vibrant and the battery life is fineMilind - Tuesday, September 7, 2010 - link
I think that's possible since my Vibrant gives me about 6-7 hours of battery life with full brightness and the screen consumes about 70-80% of my battery as per the battery usage view. I don't care since I'm typically around a charger so I set it at max brightness. But if I were to lower the brightness, I should easily be able to go for the whole day. Even at 0 brightness, the screen is surprisingly usable.I have also noticed that the only thing that drains battery faster than the screen (in my G1 as well), is if it has to hunt for a phone signal. At one time, my G1 was draining battery in about 2-3 hours, which was awful even by the G1's sorry battery life standard. It turned out to be because I was using a SIM card of a provider that had very poor coverage at the location. As soon as I swapped the SIM with another carrier, the battery life went back up. So it's possible that Sprint's causing the phones to go back and forth between 2g, 3G and 4G signals causing the battery to drain faster. It might be worthwhile to go into the Mobile Networks settings and use only 2G network to check the battery drain. Obviously this would just be to test the hypothesis. It would be stupid to buy this phone and use it only in 2G mode.

The GPS on my Pre Plus is perfect.Voldenuit - Tuesday, September 7, 2010 - link
Thanks for reviewing the Galaxy S, Anand!Probably the most requested review here. I'm actually glad that the battery life turned out to be abysmal - it helped me make up my mind about an otherwise desirable phone.
Let me explain: My fiancée had two dead Samsung Blackjacks within one warranty period. My Samsung Spinpoint F1 is dying. My mother just junked a dead Samsung TV (5 yrs old). To be perfectly frank, I have ZERO confidence in Samsung products, and the build quality of the Galaxy gives me no reason to revise that opinion.
Fortunately, the poor battery life gives me a legitimate excuse not to buy this, and I won't feel like I am missing out on anything because of a possibly irrational aversion. Sure, it's nice to have a fast phone, but by the time apps come out that make meaningful use of this, there will be *much* faster phones on the market. Buying for future-proofing is not a smart idea in the smartphone space.

PS Still looking for that 'perfect' (Android) smartphone. Evo 4G is too big and power hungry, Droid X plans are too expensive.Something like the recently announced Droid Defy might work, if only it didn't have eFuse, Motoblur, and wasn't tied to a sucky carrier.
I'm perfectly willing to wait 1 year on a post-paid phone plan for a decent phone to come out. Even the Torch would work for me, though probably not for the missus.
First and foremost for me is that it should be a phone above all things and 'smart' second. If you're going to chew the battery life tweeting and watching youtube on it, then have no juice to call AAA when you break down on the highway, it's useless to me. Integration with social apps is also something of a nightmare for me - there are people I may enjoy hanging out with on social occasions, but that doesn't mean I wish to know what they are eating, thinking, drinking or (bodily function deleted) during office hours. Somebody, please get this. So far, only Blackberry seems to. Fortunately, most other BB users are sober/boring enough that BBM is a good way to communicate for the dour, buttoned-down crowd. :p

I think it's worth mentioning that SuperAMOLED is officially a Samsung smartphone exclusive until 2012 (IMHO mostly because of limited AMOLED manufacturing capacity until the new Samsung OLED fab is up and running in 2012) . So you won't see it anywhere else in the near future. So please people, don't bitch about missing Super AMOLEDs in every smartphone that's coming in the next 18 months...Mike1111 - Tuesday, September 7, 2010 - link
Anand, your mixing your SGX versions when mentioning the OMAP3630. One time it's SGX535, the next SGX530. I think SGX530 is correct.Milind - Tuesday, September 7, 2010 - link
>>Thankfully Samsung provides a setting to sync these two so both the screen and buttons go blank at the same time, but it’s just not enabled by default.

I have seen this posted a couple of times, but I can't find any such setting on my Vibrant. Is it on the Epic? Can someone provide a little detail on exactly where this setting is? The timeout for lighting the buttons is just too short and very annoying.
Anand Lal Shimpi - Tuesday, September 7, 2010 - link
On the Epic it's here:Settings -> Sound & Display -> Keyboard timeout (last option in the list) -> Same as screen timeout
Take care,
Anand
Milind - Tuesday, September 7, 2010 - link
Thanks Anand. That option is not present on the Vibrant. The last option on the Vibrant for Sound and Display is TV out. Hopefully, it will be part of the Froyo update.
