Summary: During my research I found mostly positive reviews for the Infuse. The few user complaints I came across tended to be related to the large screen size (too big?), thin profile (fragile?), and light weight (toy like?). I too was concerned that it would be a little too large to be easily pocketable. After about a week with the device I can say that this device fits in pocket very well. It is so thin and light that most of the time I don't even notice that I have something in my pocket. I was considering a belt clip case for the phone, but probably won't get one for now.
There are several different facets that could be reviewed with this phone. Here are some of the most important for me.
Simple gorgeous. Makes even high end computer screens look bad. I had high expectations here, and they were exceeded handily. The screen has a resolution of a little over 200 pixels per inch - which is nearly three times as dense as most computer screens. It's incredibly crisp, bright, and vibrant. There is no color distortion at any viewing angle. The glass is well coated and although glossy, doesn't appear to suffer from excessive glare. The screen on my Android Tablet (Asus Transformer) is much more difficult to see in bright rooms.
--BUILD AND FORM FACTOR--
Dimensions: 2.7" wide, 5.1" high, 0.35" thick
I was concerned it was going to be too big, but I haven't found this to be the case. It fits into my pocket with ease and so far seems to resist scratches well. I've even dropped it already and the phone suffered no ill effects (not even a scratch). The back cover is a thin textured plastic piece that looks great and gives it a high end feel. The sides are a glossy black plastic and while it looks very nice, can sometimes make it tricky to hold onto. I don't plan on getting a case for the phone, but if I find myself dropping it often, then I'll look into it.
--RECEPTION AND CALL QUALITY--
In short, better than any other phone I've ever owned. I'm coming from a Samsung Impression (semi-smart phone), and the sound quality of the infuse is head and shoulders above it. Callers voices are clearer than I've ever heard from a cell phone before. This was an unexpected surprise. Reception also seems to be better than that of most other phones. I get abysmal phone reception in my apartment. Most people have to go outside to get a decent phone call. I can now move further away from the front of my apartment than I could before while still getting good reception. It doesn't sound like much, but for those who don't get great reception in their area, it could be very valuable.
This is a fast phone. I was concerned about "only" having a single core processor and "only" having 512MB of RAM, but again these concerns have been unfounded. Responsiveness of the phone is quite good and it almost never lags (slows down slightly when installing apps). The keyboard can actually keep up with my fast typing, and the swiping of screens and pushing of icons happens quickly. This phone installs and runs apps noticeably faster than my Asus Transformer, which is impressive given the huge size differential. I have zero remorse for passing up the faster Galaxy 2 for this phone.
--CAMERA AND SPEAKERS--
I won't mince words, the speakers are awful. Don't even attempt to listen to music with the built in speakers because it won't do it justice. A far better option for any type of multimedia is plugging the included headphones into the jack on the top of the phone. This gives vastly improved sound instantly.
The camera feature is a mixed bag. The sensor seems to be quite good for a camera phone, however it's hobbled by the interface. There is no dedicated shutter button, but there is a basic mix of camera controls in the included software. Image quality is good for a phone, but point-and-shoots are still better in every way. For most casual users, this camera phone will probably take the place of their point and shoot.
It comes with Android 2.2 installed and it's pretty fantastic. I have Android 3.1 on my tablet and while "3.1" sounds a lot better than "2.2", the 2.2 on the Infuse does everything I could want and then some. For 99% of the population, you could leave 2.2 on this phone and be happy for the life of the phone.
AT&T has installed a handful of branded apps which can't be removed without rooting the phone. Most are fairly unintrusive, so there is no great harm in leaving them. Most of these apps are geared towards getting you to spend more money on subscription services to AT&T when in reality you can probably find free apps to do the exact same thing. You can use "Superoneclick" and "Titanium Backup" (both free) to quickly and safely remove these apps if you are so inclined.
Aside from the handful of AT&T apps, the phone is set up very well with a couple dozen of basic, but very useful apps. Being Android, there is obviously a TON of customization here, but right off the bat you get the most basic apps to do what most people need to do. Emailing and texting are excellent on this phone straight out of the box.
--BATTERY LIFE AND CHARGING--
Again here, better than expected. I read horror stories about terrible battery life with this phone (granted these reviews are from mid 2011), but I just haven't experienced it. I typically get a full day (14 hours) out of the phone with moderate usage while only running the battery down to 30% or so late at night. While I definitely expect to have to charge the phone every day, as of now I never worry about making it through the day without charging. You can install various battery saver apps (I use Battery Dr Saver) which will extend life further.
Charging is done via a standard micro-USB cable and plugs up into any USB port. Charging isn't particularly quick, so you'll probably have to leave it overnight to charge it completely when it runs low.
So far I'm delighted with the phone. I've found the hardware to be exceptional and the software platform to be reliable and extremely useful and innovative. The somewhat largish screen on this phone just makes the software that much more usable. It performs basic phone functions flawlessly and handles moderately complex multimedia without a hiccup. While this phone is technically a step down from the Galaxy 2, it doesn't feel like a compromise phone at all. Given the exceptional price under contract, this phone is a no brainer for those looking for an upgrade.
My advice, before you're will buy the Infuse 4G, I suggest you have to check for best deal at: Androidlikeit.blogspot.com/p/samsung-infuse-4g.html
