Review: Samsung Focus Flash for AT&T
Screen
I have yet to be disappointed with the display of any Windows Phone device. The Focus Flash has a 3.7-inch capacitive display with 480 x 800 pixels. Packing that many pixels into the smaller display gives the Focus Flash a nice boost in pixel density — which makes the display look razor sharp and free and clear of any visible pixels. It's also insanely bright. I was able to use it indoors and out with no problems. Bottom line: another great display on a Windows Phone.
Signal
The Focus Flash performed amazingly well in my signal tests. No matter where I took it, it always remained tightly attached to AT&T's network. Held side-by-side with other AT&T devices, the Focus Flash showed more bars consistently. Every call I made went through on the first try, and none of them were dropped — even when the Focus Flash showed only one bar of coverage. Similarly, data sessions were rock solid for the most part, with only a few speed hiccups under the worst network conditions.
Sound
Voice calls made with the Focus Flash sounded great. The earpiece generated enough volume so that I could easily hold conversations even though I was blasting Megadeth in the same room. Quality was excellent, the best I can recall from an AT&T device in recent months. Ditto for the speakerphone. Calls were crystal clear, and also loud enough to be useful over some metal music being played in the background. Ringers and other alerts can be set to volumes loud enough to be heard in most environments. If you need to be more discrete, the vibrate alert is strong enough to make sure you know there's an incoming message or call.
Battery
The Focus Flash had really good battery life. It routinely lasted about a day and a half with both the cellular and Wi-Fi radios active, with location services on, and a lot of web browsing and other usage. Heavy users will want to charge every night, but can rest easy knowing they'll make it through each day with no problems.
