The screen on this multimedia cell phone is large and gorgeous

from Top Ten Reviews

As its name suggests, this multimedia cell phone runs on the 4G network. However, AT&T's 4G network has been slow for a 4G network. The Infuse 4G has a 1.2 GHz processor and runs on Android 2.2. We've reviewed other multimedia phones that have had dual-core processors and run on Android 2.3, so this phone isn't as fast and efficient; however, it isn't slow either. You may notice a little lag but not much. The Samsung Infuse 4G has a longer battery life than many of the multimedia cell phones we reviewed. It supplies you with just less than nine hours of talk time. It also comes with a large... Full review


The Infuse 4G looks by all means like a true flagship but fails to deliver in the performance section

from GSMArena
As it seems the Samsung I997 Infuse 4G has pretty good chance of completing its mission. It will ensure that those who want a new smartphone right now get plenty of bragging rights for a while and will still leave them with the largest Super AMOLED Plus display in the world when it imminently gets outdone by the AT&T version of the Galaxy S II and perhaps even the iPhone 5 or 4s in a few months...

It's an all-around solid device that rarely disappoints

from Phone Scoop

The Samsung Infuse's stand-out feature is its gigantic, 4.5-inch Super AMOLED Plus display. Almost every other feature can be found on other Android devices. The Infuse's display is certainly impressive, but it makes for a larger-than-life device that may literally be too big for some users.

I was a little disappointed by the Infuse's performance in some key essentials, such as voice quality and battery life. Network performance was acceptable, however, as was the overall user experience and performance of this 1.2GHz-powered powerhouse.

The music and video experienc... Full review


A great phone for the media-hungry consumer, but a few issues keep it from being great

from PCWorld
The Samsung Infuse is a great device for media consumption, provided you can get over the text- and image-rendering issues. Reading pixilated text on that otherwise gorgeous 4.5-inch display is just a tad heartbreaking, to say the least. But if you are someone who is likes to watch movies on the go, then this is the phone for you... Full review

The Infuse 4G disappoints in some areas, but is still a very good Android smartphone as long as you're OK with the larger design

from Cnet

AT&T has slowly but surely been beefing up its selection of Android phones, and the Samsung Infuse 4G is another good addition to its lineup. There are certainly some aspects of the phone that were disappointing, including the unimpressive 4G data speeds and the lack of some of the latest features (such as Gingerbread and a dual-core processor), but in the end, the Infuse 4G is very much a solid Android smartphone. Obviously, its large size will mean it won't appeal to everybody, but if you're OK with that, you'll get a beautiful screen for browsing the Web and watching video, good perf... Full review

The Infuse 4G's mammoth 4.5-inch display has some benefits, but it's held back by AT&T's slow network

from Laptop Magazine

The Samsung Infuse 4G has plenty to offer--a sleek design, a good camera, and a big and vibrant screen. However, even though this device is thin and light for a 4.5-inch smartphone, using it one-handed can feel awkward because of the large footprint. What's more, having extra real estate makes waiting for content to load over AT&T's network all the more agonizing. For Android fans, we prefer the Motorola Atrix 4G on AT&T, which sports a more powerful Tegra 2 processor and a smaller but higher-resolution display. And if you're not wedded to Ma Bell, consider the T-Mobile G2x, which o... Full review


A quality device that deserves a chance as much as any of the better Android phones out there

from InfoSync

Our InfoSync Diagnosis with the Samsung Infuse 4G is a good one. The phone managed to hit several core requirements that solidified it as a worthy device in our book. First off, the phone's massive 4.5-inch Super AMOLED Plus display not only gave us the graphics goods, but it managed to aid in the conservation of battery life. Speaking of battery life, the Infuse 4G performed exceedingly well, proving itself as one of the best devices when it came to stamina. The phone was also faster than most of its peers, courtesy of the 1.2GHz processor, and it was about as thin as an iPhone 4. The Infu... Full review

If you like big screens, look no further

from PC Magazine
Don't believe the hype: the Samsung Infuse 4G may be AT&T's first true 4G cell phone, but AT&T doesn't appear to have the network to back up the Infuse's HSPA+ 21 speeds. The Infuse is the first phone we've tested that packs an extra-large, 4.5-inch touch screen. It's also amazingly thin—thinner even than the on T-Mobile. Still, a few quibbles here and there add up to a phone that's very good, but not great... Full review

A stunning screen that's big and the kind of battery life that could finally put your charge anxiety to rest

from Engadget
The Infuse 4G is another solid offering from Samsung that we think those of you with wide pockets and big hands are going to fall in love with. It doesn't quite reach the blistering processor speeds of the Atrix, doesn't have a fancy composite back, and is completely bereft of laptop pretenses. It does, however, have a stunning screen that's big and the kind of battery life that could finally put your charge anxiety to rest. Maybe, just maybe, you could leave that second battery at home...

It may not be the 4G phone you’ve been waiting for, but it’s still worthy of your attention

from BGR

No, it’s not the 4G phone you’ve been waiting for, but it’s still a solid device. I’m shocked that AT&T can get away with calling this a 4G phone, however, because I have yet to see data speeds that push the boundaries of its network. But if AT&T making good on its “4G” claims and delivering solid data speeds isn’t a necessity for you, the Infuse 4G is worthy of your attention. The screen is incredible, I like the thin form factor, and the solid battery life was definitely appreciated. Samsung’s TouchWiz user interface isn’t for... Full review
