On the video side, 720p HD capture is available, but it strangely isn't selected by default, so you'll need to choose it yourself for the highest-quality clips. For smaller videos you plan to upload or share, you could also opt to drop down a few resolution notches.
Video quality itself was perfectly acceptable in 720p HD, especially for the type of phone this is.
I can't say the same for the front-facing VGA camera, which took grainy, blurry photos. While you can use it for video capture and chats, your friends on the other side are going to see a whole lot of blur and not much you.
If you plan to take a few photos and any video, then you're also planning to invest in some external storage -- up to 32GB. The Amp's 4GB limit is really more like 1GB and a little more for your own use, and installing apps and shooting film will eat through that threshold before you know it.
Call quality was impressively strong when I tested the Galaxy Amp (GSM 850/900/1800/1900) in San Francisco using Aio's wireless network.
I could hear my testing partner well on medium volume, and never needed to raise the levels or activate the extra onscreen audio boost control. The call was perfectly clear and voices sounded natural to my ears, although my partner did sound slightly muffled and tufts of distortion cropped up here and there. On his end, my testing partner called the Amp's call quality one of the best he's ever heard. It was clear and loud, and had terrific fidelity without any noise or distortion.

Speakerphone was also great overall when I held the phone at hip level. My partner's voice sounded higher, more shrill, and a little buzzy, but I still didn't have to adjust the volume and the call didn't pick up too much echo. On the other end of the line, speakerphone remained excellent, with warm, human voices and only minimal room echo.
Aio's 4G speeds were consistent when I took the Galaxy Amp around San Francisco, but not anywhere near as fast as parent AT&T's LTE network.
Speeds measured through the diagnostic Speedtest.net app consistently hovered in the 3Mbps downlink range and 1Mbps up. Consistency is key, even if these registered as 3G rather than 4G speeds. In real-world tests, mobile-optimized Web sites like CNET's still loaded swiftly enough, and apps downloaded and installed without too much trouble. If you stream video and radio you'll notice a lag compared with faster phones, but for everyday communication use, performance was far from crippling.
The same can be said for internal performance, too. You get what you pay for with the 1GHz dual-core processor, which is far from being Samsung's most high-performing. Again, if you've never used a top-of-the-line device, you won't know the snappiness you're missing. Gamers won't show the fine detail they would on a top-of-the-line device, but that's no surprise.

Battery life should last through your workday on the Amp's 1,500mAh ticker, which has a rated talk time of 7.5 hours over 3G and 16.7 days in standby mode. That's less exact when you're using 4G, but we'll fill in with results from our in-house battery drain test.
As for radiation levels, the FCC measured a digital SAR of 0.77 watt per kilogram.
It's gratifying to see more and more smartphones come in below $150 off-contract. There's always a trade-off between price and features, but I'm gratified that Samsung nailed it on call quality, and the rest of the feature set, if not supercharged, is at least complete.
If you're within Aio's extremely limited startup footprint, the Galaxy Amp is stacked with more up-to-date goodies than Android phones from MetroPCS and Boost Mobile for about the same price. However, no-contract shoppers open to Windows Phone should still check out T-Mobile's .
As for Aio itself, how well AT&T can wield Aio against T-Mobile, and Sprint's Boost Mobile and Virgin Mobile to a lesser extent, comes down to how quickly the network can expand. With the Galaxy Amp and a few other smartphones, Aio is off to a fair start.
