Samsung Epic 4G (part of the Galaxy family)a long-term test by Philip Greenspun, February 2011 |
The 800x480 pixel Organic LED display on the Samsung Galaxy phones,
including the Epic 4G, is so much more attractive than the
conventional LCD displays to which we are accustomed that you'll want
to use it all the time just to admire the jewel-like beauty of a
photo, a video, or even simply the icons and interface.
Why does the display look so great, especially indoors? A big part of it is the contrast. On an LCD display, black is "however much remains after we try to block as much as possible of the backlight". On an OLED display, black is "off" and therefore is "whatever ambient light reflects off the front of the phone".
To conserve battery power, the display never actually gets as bright
as a lot of LCDs, e.g., the Droid 2 or iPhone 4. The LCDs are
therefore more readable in bright sunlight.
If you can resist draining the battery by admiring the display, the
Epic 4G's battery can just barely last through a day of checking email
and making a few phone calls if and only if you're in an area
with good coverage. In a rural or otherwise poorly covered area, the
phone exhausts its battery within just a few hours trying to boost its
radio output.
If your home or office has weak coverage and you can't live without
the Epic 4G, it will be worthwhile to invest in a Sprint nano-cell or
"range extender" such as the Sprint
Airave that will back-haul conversations via your
home or office Internet connection. A wireless repeater that would
also work.
Another great thing about the Samsung keyboard is that it has a full five rows of keys, including a dedicated row of numbers. I also like the fact that the keyboard conveniently replicates the "menu", "home", "back", and "search" buttons from the front of the phone.
It is sad that there wasn't room for a second shift key and also that the keys are so flat. When I compared myself to the guy typing on an iPhone in this speed test video, I clocked in at about 27 seconds, i.e., 4 seconds slower than the iPhone expert (the same phrase took me 7 seconds to type on Microsoft Natural (desktop) keyboard).
Privacy advocates will be heartened to learn that GPS
latitude/longitude coding of images is disabled by default. For
someone accustomed to using conventional digital cameras, such as the
Canon EOS series, the camera controls seem more logical and require
fewer clicks than on other Android phones, e.g., the Droid 2. (This
may reflect Samsung's experience as a manufacturer of a range of high
quality cameras; note that in 1995 Samsung acquired Rollei, one of the
world's oldest and most distinguished camera manufacturers.)
The 5-megapixel camera is located in the center-side of the back of the phone, much more likely to be out of the way of fingers than a camera in the corner of the case (e.g., iPhone 4, Droid 2). Remember that high resolution and a tiny sensor can work well in bright sunlight, but photos taken near dusk will be extremely noisy:

What good is 4G then? You can watch high quality streaming video from sites including YouTube.
The Epic 4G gives you a choice between Sprint Navigation (Telenav) and
the standard Android Google Maps. The Sprint Navigation system is very
similar to a portable dedicated GPS or one of the $2000 factory
navigation systems from a car manufacturer. One of my most depressing
experiences ever with a computing device occurred using Sprint
Navigation at the Orange County Airport. I typed in my cousin's
address in Los Angeles and the program calculated that it would take 57
minutes to get there. Then it said "checking traffic information" and
recalculated the time as 3 hours. It took me about 2 hours and 55
minutes. Maybe we would be happier if computers did not tell us what
our life was going to be like.
Google Maps is included and does all of the things you'd expect, including shockingly smart voice recognition of destinations.
With either program the GPS reception was rock-solid, with the phone on my lap or in between the front seats.
To use the Epic 4G as an MP3 player, plug the phone into your computer
via USB. If not already there, create a top-level folder called
"Music", then copy the albums you want into the folder. Neither
iTunes nor Windows Media Player will recognize an Android phone as a
music playing "device". If you prefer to transfer your music via a
similar interface, try doubletwist.com.
The phone has a standard 3.5mm headphone jack (same size as Walkmen,
iPods, etc.) and also can stream music via Bluetooth to a car or
headset (I've had good luck with the Sony
DRBT50).
As of March 2011, the phone is $200 with a two-year service
commitment. Sprint's published rates are competitive with other
carriers: about $70 per month for unlimited data and some voice
minutes; about $100 for unlimited everything. Sprint has an additional
$10/month "data package" charge for smartphones, so add $10 to the
prices that you see quoted. There is no extra charge for using 4G
versus 3G, however.
The Epic 4G is a great example for why smartphones, like laptop computers, should come in at least two different versions from the factory: standard (light and impressive in stores), useful (with 3X the battery life). There are third-party companies that sell bigger batteries for phones, but the mechanical integrity of the case is compromised.
If you must have the world's most advanced mobile phone, the Epic 4G should be on your short-list.
The image processing system does a remarkably good job with high-contrast scenes, retaining good detail in highlights and shadows:
You will need to manually add +1 f-stop of exposure when taking photos in the snow:
Depth of field is good, thanks to the small sensor and therefore short focal length lens:

Nicely presented information in this post, I prefer to read this kind of stuff. The quality of content is fine and the conclusion is good. Thanks for the post. <a href="http://www.clickindia.com/search.php?q=samsung+cdma+mobiles" rel="follow" rel="nofollow">samsung cdma mobile</a>

I've just retired my Epic 4g after a bit over two years of use, and can confirm your review is quite accurate and insightful. Other than one glitch with Sprint's technical support not believing me that my account needed to be re-provisioned, I really enjoyed my Epic. I am slowly warming up to it's replacement, a Galaxy S III, since I knew I would miss the great physical keyboard. As a long-time admirer, I got a tiny bit of a buzz knowing you had the same phone!
