Phone Scoop

Pretty good call quality and excellent battery life

from Phone Scoop

There's nothing inherently wrong with the Samsung DoubleTime. It's a fine phone in most respects. It's also completely boring. For a device that is obviously aimed at helping bridge the gap between quick messaging devices and mid-range smartphones, the DoubleTime offers few unique or interesting features.

It works well as a phone, battery life is good, apps perform well for the most part, and it can help get the old QMD user in the smartphone door.

For $50 it's hard to knock the DoubleTime for anything serious, and there's a significant lack of $50 QMDs available from AT&... Full review


Honestly, the DoubleTime is not worth your consideration

from Phonedog

I've been pleasantly surprised by a number of low-end and mid-range smartphones that offered performance that far exceeded my expectations for such a device. The DoubleTime is not one of those phones. Outside of its stellar QWERTY keyboard, there's nothing that convinces me that this is the phone you should go for, even if you are on a budget. I would recommend looking at other options from AT&T like the HTC Status, LG Phoenix, Samsung Focus Flash, or Samsung Infuse (on sale right now)- all of which can be had for the same price of the DoubleTime or cheaper and will offer a much better smar...

It looks and feels like a feature phone, but it runs Android and requires a data plan

from The Verge

AT&T wants you to believe the DoubleTime is an inexpensive smartphone — if it is, it’s as bad a smartphone as I’ve used in a long time. Requiring a data plan with this device is a huge mistake that totally dooms the DoubleTime, because at the cost of ownership I can’t possibly recommend the phone to anyone. But as a feature phone, for $49.99 with a contract, it has definite potential. It’s solid for messaging, runs basic apps well, and does all the things you’d need a basic phone to do — plus a few more. When you can buy an iPhone 4 for $99, or... Full review


You’re better off investing the money on something considerably better

from PhoneArena
Seriously, for $49.99 on-contract, you’re better off investing the money on something considerably better – especially when there are a variety of other smartphones that tastefully show off the beauty of Android. To tell you the truth, the Samsung DoubeTime is somewhat of an injustice in the Android family since it’s packing an aging Froyo build and suffers from a very sluggish overall performance. Yes, its dual-screen clamshell form factor is intriguing, but it simply isn’t accompanied with an acceptable experience... Full review

The Samsung DoubleTime has two displays and a keyboard, but that isn't reason enough to buy it

from PC Magazine
The Samsung DoubleTime has a hidden surprise inside: a full QWERTY keyboard with a secondary display, turning it into a micro-laptop. Unfortunately, it doesn't deliver the performance to go with its ambitious look. Even if you absolutely need a keyboard, you can find a better smartphone on AT&T than the DoubleTime... Full review

The lower-end specs and outdated Android OS do the phone no favors

from Cnet

Samsung and AT&T took the plunge on the DoubleTime's more singular looks, a chancier move since the bulkier, shorter, and pinker form constricts its mass appeal. If, like me, you take a shine to the handset's appearance, dual-screen design, and call-quality bonus, you might (like me) ask yourself if the second screen significantly adds to the experience. It may add little other than bulk to make the keyboard a clamshell design rather than a slider, but to me, it doesn't detract. However, the Froyo OS, duller camera, and slower processor might keep you from committing. The $50 cost is re... Full review

Android Community

It’s worth considering for family members or friends who aren’t interested in Ice Cream Sandwich or massive screens

from Android Community

As an Android fanboy, the choice to limit the DoubleTime with Froyo really, really gets on my nerves. But from the perspective of a first-time smartphone buyer, who just wants a phone with a great keyboard and decent call quality, with Android and app installation as an after thought, it’s a pretty good choice. Music fans and shutterbugs will want a bigger SD card, but excellent battery life means that this little phone is ready for lots of service in between charges. The DoubleTime probably isn’t the phone for our most dedicated readers, but it’s worth considering for fam... Full review


It holds some sway in its own lower level of internet-capable handsets

from SlashGear

While this smartphone is far and away, not even in the same ballpark, basically not even the same sport as the top tier smartphones also made by Samsung such as the Galaxy S II or even the top of middle-tier devices like the Samsung Captivate Glide, it does hold some sway in its own lower level of internet-capable handsets. This device looks rather unique with its mostly white and black chassis and pink accents, and the double touch displays are certainly a nice touch. Get this phone if you’re the type of person who only plans on using this first-timer smartphone for email and Faceboo... Full review
