In addition to plugging into the social scene, the FX also comes preloaded with other apps, including geolocation software like Where and Loopt, and Yellow Pages Mobile. There are also games like Diner Dash, Tetris, and Uno, and of course, there are storefronts for purchasing more games, apps, and music. Multitasking is a hot topic in the smartphone world, and an unexpected perk on the FX. Pressing and holding the center/back button will produce a list of commonly used apps so you can switch from one to another without you having to necessarily close the app and return to the home screen.
When it comes to browsing, AT&T has opted for the clunky-looking, but fairly fast att.net browser, a branded variant of Opera Mini's proxy browser (which compresses Web pages on Opera's server before sending them down to the phone--this facilitates speed) that's been tailored by AT&T to fit its requirements. Predictably, there's no pinch and zoom and no Flash support. However, you can search the Web and access shortcuts for the weather, headline news, and the like.
No midrange feature phone is complete without music, and like many of its kin, the FX's music is provided through the AT&T Music app services. This is a gateway for a number of third-party music services, many of them subscription-based. They include streaming radio, a song-identification service, and streaming video. The music store typically charges $1.99 for a song and has package deals to boot.
If you've already got your own music loaded onto an SD card, you can also play songs in MP3, AAC, eAAC+, AMR, and MIDI formats through the music player. This is the stock music player AT&T uses on many phones, including the Quickfire. In addition to creating and editing playlists, you can command songs to repeat or shuffle, and you can also tinker with equalizer settings. The lack of hardware controls for easily pausing and skipping tracks will disappoint music aficionados, but since the FX is billed as a texting phone and not a music phone, we can't really fault it. The FX has 80MB internal storage and can accommodate 32GB of expandable memory in the SD slot. You'll need to buy external memory separately.
Music and streaming videos aren't the only entertainment available on the FX. Since Mobile TV is such a big deal these days, we're pleased to see AT&T include an optional $9.99-per-month subscription to AT&T Mobile TV, the streaming-TV service that's powered behind the scenes by FloTV. We didn't seem to have access to every channel on our test device, but we did watch "Let's Make a Deal," "The Bachelorette," and "Hell's Kitchen." Video quality was decent, but a little choppy and out of focus. You can read up on more details in our side-by-side review with the LG Vu. Thankfully, pricing has since deflated to a more reasonable amount since AT&T Mobile TV debuted.
When it comes to taking your own videos and stills, you'll look to the 2-megapixel camera. It captures shots in four resolutions (1,600x1,200 pixels; 1,280x960 pixels; 640x480 pixels; and 320x240 pixels), and it has three quality settings, and five white-balance presets. There are four color effects, six fun frames, a self timer, and 4x zoom. On the video side, you're looking at two resolutions (320x240 and 176x144 pixels), and the same three quality settings and color effects as the still camera. The photo quality looked crisp for perfectly still shots, though colors were slightly muted. Videos were blurry and also muted during the recording process and on playback, but with these camera and camcorder specs, that's to be expected. Though neither is stellar, you'll be more than capable of getting your point across through pictures and movies.
It's possible to take video recording one step further with Video Share, a service for broadcasting live-streaming or prerecorded video to another AT&T user. The caveat is that Video Share will only work between phones that both have the specific app installed; sounds like another video app we know. Also, both parties must be on 3G throughout the call. Unfortunately, we weren't able to test this feature during our evaluation.
Though AT&T's user interface is stamped all over the FX, you can still add your own flavor by customizing the phone with wallpaper and alert tones. As with some other AT&T phones, you can select "Answer tones" that callers hear instead of the typical ring when they call you.
We tested the quad-band (GSM 850/900/1800/1900) Sharp FX in San Francisco using AT&T's service. Call quality varied, but was mediocre on the whole. On our end, we heard an echoed effect with some indistinct words. On calls made outside, we had to ratchet up the volume to hear anything; we even terminated one call early because the muffled voices and low volume of our caller couldn't compete with the ambient noise of a bustling downtown. Indoor calls sounded truer, but a background hiss often persisted.
Callers' impressions also varied. In some calls, they said we sounded tinny and slightly flat or distorted. Our volume was loud and clear, however, and any distortion heard on their end was fixed if we spoke louder. The speakerphone was fairly weak, as it usually is, with a noticeable drop in volume on the listener's end, a fair amount of distortion, and the return of that background hiss. Still, conversations flowed fine when the FX was 6 inches away from our mouth, with quality rapidly degrading after that mark.
Though the moments of poorest call quality did affect our calls, we were mostly able to hold conversations without deal-breaking interference. However, based on our experience, we wouldn't recommend the FX for chatterboxes who enjoy long conversations.
The Sharp FX has a rated talk time of up to 3 hours, which is on the low end, and 10 days of standby time. Our tests revealed a talk time of 4 hours and 21 minutes. According to FCC radiation tests, the FX has a digital SAR rating of 0.468 watt per kilogram.
