Phone Scoop

Boasting speedy performance, a solid camera and of course Microsoft's Mango operating system

from Phone Scoop

The Focus S takes all the good things I saw in the Focus Flash and offers them in slightly larger and better-looking package. The Focus S performs well across the board and there's little negative I can say about it.

The worst problems the Focus S has are related to Windows Phone 7's rigid appearance and behavior. If you don't care all that much about customizing the appearance of your smartphone, however, this needn't concern you.

Bottom line? All three Windows Phone 7.5 Mango smartphones offered by AT&T are excellent devices. The HTC Titan is the enormous Father... Full review

Going for the Samsung Focus S is a choice you are unlikely to regret

from GSMArena
It seems hard to find a better player than the Samsung Focus S in the US Windows Phone game at the moment. The device’s hardware is as good as it gets for the platform, but its main selling point is certainly the Super AMOLED Plus screen – its ultra-deep blacks and Microsoft’s Metro UI are a match made in heaven.However Microsoft’s hardware limitations do not allow for better differentiation between budget and high-end Windows Phone devices and that may steer a lot of people clear from spending extra cash on the same user experience...

It’s clearly fashioning a foundational core to set it apart from other Windows Phones

from PhoneArena

Unlike its Android counterpart, the Samsung Focus S lacks the prestige and notoriety of its close sibling, but more importantly, it’s clearly fashioning a foundational core to set it apart from other Windows Phones. Impressively, it’s the best Mango filled device to own right now, edging out the HTC Titan just by a tiny bit, mostly because it snaps the better photos and videos between the two. Add in that it’s able to pique our interests thanks to its Super AMOLED Plus display, fast performance,  light weight feel, and thin profile construction, they all come... Full review

Great display, snappy performance, thin design

from MobileBurn

The Samsung Focus S is an impressive and enjoyable smartphone to use. While it is not perfect by any means, and it suffers from Windows Phone's continuing growing pains, it has some really great qualities that make it worth a look for anybody in the market for a new smartphone. The only real negative might be its price ($199 on-contract), since the Focus Flash offers a very similar user experience for significantly less money up front. However, if you are able to get over the sticker shock, you will be rewarded with a larger, nicer screen and a much better camera, not to mention a f... Full review

Mobile Tech Review

Lovely OS, excellent display, very thin and light

from Mobile Tech Review

It's hard to not like a smartphone with serious Samsung Galaxy S II DNA when married to the elegant and enjoyable Windows Phone Mango OS. The display is lovely and Samsung's Super AMOLED technology makes those colorful Live Tiles pop. The phone is fast; in fact it's extremely fast. That's a testament to Microsoft's optimization for second gen single core Qualcomm CPUs and the added benefit is better than average battery life compared to other smartphone platforms. The Focus S easily lasts through the day, even with heavy use. Call quality is top notch and reception is good. The camera takes... Full review

The Samsung Focus S packages Microsoft's attractive Windows Phone OS with a stunning screen and slim Galaxy S II style

from Laptop Magazine
The Samsung Focus S serves up a compelling Windows Phone 7.5 Mango experience in a thin and attractive package with a great display. And assuming the price stays at $99, this smartphone is a good value, putting it between the $49 Samsung Focus Flash (which has a smaller 3.7 inch-screen and a lower-res camera) and the $199 HTC Titan (a massive 4.7 inches). Still, we'd prefer a faster camera, and the data speeds aren't the best AT&T has to offer. But if you like the idea of owning a Windows Phone, the Focus S is a solid mid-range choice... Full review

Bolstered by a brilliant display and strong hardware specs, the Samsung Focus S is arguably the best Windows Phone ever released

from Cnet

Samsung has definitely led the way with Windows Phones, from the original Samsung Focus to the loosely related Focus Flash and Focus S we see now. Any way you look at it, the Focus S, with its clean, attractive, powerful minimalism, is easy to use and lets Windows Phone shine. There are few overt flaws, and the device brings Microsoft's mobile platform the closest it's ever been to being in direct competition with Android and iOS superphones. However, as much as I recommend the device for day-to-day use, the analytical part of me can't help but feel like Samsung is cheating just a little bi... Full review

A solid phone that doesn't quite feel deserving of its high-end price

from Engadget

Honestly, we don't have any major complaints about the Samsung Focus S, but there wasn't much that wowed us either. If you're a Windows Phone 7 fan you'll find plenty to like about the device. Mango hums along nicely and the Super AMOLED Plus display, despite its shortcomings in the pixel density department, perfectly highlights the stark beauty of Microsoft's mobile OS. There's also a very good camera with a dedicated dual-stage button and the battery life borders on epic. But, none of that changes the fact that we came away feeling underwhelmed. The build quality is mediocre at best and t... Full review

The excellent battery life is sure to make your Android and iPhone friends jealous

from Pocketnow
Last year's Samsung Focus was arguably the best Windows Phone available so I was certainly expecting Samsung to step it up with their second generation Windows Phones. The Focus S is actually the high-end model among two new Samsung Focus phones with the Focus Flash being a more budget-friendly device. At $199 you'd expect the Focus S to be quite good and it certainly is... Full review
