Swype Keyboard

Swype Keyboard

An alternative to the Android virtual keyboard, the Swype virtual keyboard allows you to input text by swiping the finger with one continuous finger or stylus motion across the screen keyboard. Based on testing, speed and accuracy are equal to or better than the traditional keyboard-tapping method. You can activate the Swype keyboard by pressing and holding in a text field, wait for popup to appear, click Input Method, and then select Swype.

In the image to the right, the word "quick" was generated from tracing the path shown above in a fraction of a second, by roughly aiming to pass through the letters of the word. A key advantage to Swype is that there is no need to be very accurate, enabling very rapid text entry.

AT&T 4G Network

This phone runs on AT&T's dual-band 850/1900 MHz 4G network (UMTS/HSDPA/HSPA+), and with HSPA+ you'll experience mobile data speeds up to 4x faster than ordinary mobile broadband--up to approximately 6 Mbps (download). AT&T has deployed HSPA+ to virtually 100 percent of its mobile broadband network, which enables 4G speeds when combined with enhanced backhaul (via Ethernet or fiber).

Backhaul is one of the major pieces of a telecommunications network. Think of it as the limbs connecting AT&T's cell towers with AT&T's backbone network that provides access to the Internet.

Coming later in 2011, AT&T will deliver a second layer of 4G network called LTE (Long Term Evolution) that is even faster than HSPA+ speeds.

In areas where either AT&T's 3G or 4G network is not available, you'll continue to receive service on the AT&T EDGE network, which offers availability in more than 13,000 US cities and along some 40,000 miles of major highways.

Note: AT&T's 4G mobile broadband coverage is not available in all areas. 4G speeds delivered by HSPA+ with enhanced backhaul; availability increasing with ongoing backhaul deployment.

By Todd Stevens on May 19, 2011
I've never had a phone or PDA where I didn't have to sacrifice a lot to get something else. Not with this one. I am a Google addict. I use Google Docs, Tasks, Contacts, GMail, Calendar, etc. So of course this phone works perfectly with all of that and syncs well with my Galaxy Tab, Windows 7 PC and MacBook Air.

Before this I had a Captivate running Froyo and wasn't sure if switching would be worth the cost, as I mainly have just wanted a bigger screen. I don't know why iPhone does so well at only 3.5". You can't read text on something that small. I could barely stand 4" Captivate. 4.5" seems to be the sweet spot. Especially since the phone is so thin and light. Perfect width for telephone conversation and surfing, typing.

The biggest surprise though is the battery life. I have never had a smartphone last a whole day and I do not talk much on them or play media. Just surfing, texting and updating calendar, tasks, etc usually drains the battery. On my Captivate I could go about 12 hours if I used a black background, turned off 3G, turned off WiFi except when needed, etc. But with the Infuse, I took it out of the box 1/2 charged Monday evening. Charged to full charge (takes up to 4 hours from 0%) and took it off the charger at 10:40pm. Tonight is Thursday and at 9:30pm it finally died! Nearly 3 whole days!! I used a 1/3 of each day with FaceBook Go Chat open on it, full color wallpaper, never turned off WiFi in the entire 3 days. Screen brightness has been on medium or Auto. Just normal use, nothing heavy and nothing to intentionally preserve battery. That in itself justified the cost.

But other perks have been how fast menus open and apps launch compared to some lags in Captivate.

You are going to hear a lot of opinions on how this phone isn't dual core, isn't the Galaxy S II, too big, blah blah blah. Unless you simply must have the "next generation" phone this fall, if you are looking for the BEST AT&T Android phone, the Samsung Infuse is it.

On paper, I didn't upgrade by much...I already had the pretty good Samsung Captivate. But after a few minutes with the Infuse, I could already tell this was a great phone. The performance is so snappy and quick. I don't have official benchmarks but for instance, I am a heavy Google Reader user. On the Captivate, when I would choose "Mark All Previous Read", it would take, on average, 10 seconds. Now, it is about 1 second. This is on both Wi-Fi and "4G". App loading and closing is also much faster. I did have my home menu in a long "spinning symbol" after running some apps and I even rebooted but it has since not returned.

The screen is absolutely beautiful. Bight, big and sharp. The screen size was the selling point for me and it feels good in your hand. Slightly larger feeling but I expected it to feel much bigger.

Multimedia is also a joy to use on this phone. The front facing camera is a nice addition and I like having the flash on the 8MP camera on the back. We did try a Tango video call and never could get it to work right. If we weren't sideways, then it wasn't displaying correctly. Someone needs to make a definitive video chat client for Android.

To me, this phone is ready for the future. Even with dual core processors out there, this phone should do you for at least the terms of a 2 year contract, if not longer. If you simply can't wait for the fall lineup of phones, this is an excellent choice.

I used the iphone 2G, 3GS and iphone 4. Of course the last one had major issues with the dropped reception. I have been looking for an andriod phone to get me off Apple and iphone, but NO ONE could match the touch feeling of the iphone. Blackberry touch, you have to tap several times, even Motorola Atrix the response was not great and I returned it. Besides that in the Atrix email program, I could not see Html mail well. Then I heard that Samsung makes the screen that iphone uses and I had heard good feedback on the Galaxy series, that their touch was super. I decided to go with a Samsung product.

Outstanding. Impressive. Forget Iphone.
Touch: the response is super, even better than the iphone. Yes even better.
HTML Email: Excellent, reads it very well.
Speed: Excellent processes requests very fast
battery: Wow! for the smartphones these days that barely last a day, I have gone 3 days so far and not needed a charge. Although, I have GPS turned off, Wifi turned off and power management fully on. I am not a heavy user, I just want my email, little browsing and a bit of phone. yet for me, the Atrix&iphone4 would last 2 days at best.
Screen: its very big and beautiful, which I like very very much. If you are into watching videos etc with your phone you will enjoy it.

I say drop your iphone and get this.

What can I say. I really love this phone. It's quick. It's fast on the download. Typing is accurate. The camera is good. The styling is great. It's slim. Having the larger screen just makes everything so much easier - and it's exciting for multimedia.

I was disappointed that Tango wasn't working quite right, so I went to the Tango Web site to find a cure. Evidentally, there are a few different Samsung phones, including the Infuse, that are having trouble with sending a rotated and zoomed in video to the other party. The tech support said that they are aware of the problem and that the engineers are working on a fix.

One great benefit - you can use the Amazon App Store without taking extraordinary measures or rooting the phone. This is not possible on all ATT phones, so it's a welcome change. It means you can take advantage of the free app they offer every day and use your Amazon account to purchase apps.

I was worried about the phone fitting into my jeans pocket and allowing me to sit down. I found out that if I rotate it sideways, I can sit down easily. It's very slim and light, so you don't feel like you are carrying a brick. I'm so happy that I got this phone.
