Informr score
The Samsung Galaxy S 4G currently has an Informr score of 7.8 out of 10. This score is based on our evaluation of 12 sources including reviews from users and the web's most trusted critics.

The Samsung Galaxy S phone was released to much fanfare in March of 2010 and quickly became the most successful phone in the history of Android phones, selling 10 million units worldwide by the end of 2010. Versions of the Galaxy S included the Epic 4G, the Fascinate, the Samsung Vibrant for Bell Canada as well as a Vibrant brand for T-Mobile in the U.S. Less than a year later, in February of 2011, T-Mobile introduced an upgrade to their Vibrant, the Samsung Galaxy S 4G.

At first glance, there does not look to be much difference between the Galaxy S 4G upgrade over the Vibrant. The design of the two smartphones are nearly identical, with only cosmetic changes made to the design, but there are some improvements under the hood, as well as some added features.

The most obvious change is the addition of a 2-megapixel, front-facing camera, missing in the Vibrant, allowing for video calls. In addition, the Samsung Galaxy S 4G ships with a larger battery, offering a talk time of 6.5 hours, a significant improvement over the Vibrant.

The impressive features of the Vibrant are left intact. The Samsung Galaxy S 4G features the same AMOLED touch screen as the Vibrant, an excellent display technology that needs no backlight, featuring bright, rich colors and true blacks. A 5-megapixel camera in the back is capable of 720p HD video recording, offering sharp, clear videos even in low-light conditions.

The Samsung Galaxy S 4G's download speeds are snappy, with speeds advertised up to 21 Mbps. Mobile websites display instantaneously and even large, high-quality web videos load quickly and play well.

Accessories bundled with the Samsung Galaxy 4G include a USB cable, a 16GB microSD card, a headset as well as the 2010 Leonardo DiCaprio film, "Inception."

In addition to cellular calls, utilizing T-Mobile's towers, the Samsung Galaxy 4G is able to make calls over a Wi-Fi network for no additional charge. Samsung's Media Hub video store allows users to purchase videos on the go by charging purchases to their monthly bill.

On the downside, the camera for the Samsung Galaxy 4G does not come with a flash, unlike other Android smartphones. Curiously, the Samsung Galaxy S 4G ships with only a 16GB SD card and no internal flash storage. Although navigation is brisk, this lack of internal flash limits the number of apps that can be stored, a common user complaint.

In the end, the Samsung Galaxy S 4G is an impressive smartphone and for new T-Mobile customers, the Samsung Galaxy 4G is one of the best smartphones on the market. For existing T-Mobile customers with the previous generation Vibrant, especially those still under contract, there are probably not enough added features to upgrade.

What the Critics Are Saying...


The S 4G is essentially a mildly tweaked Samsung Vibrant with a couple of extra goodies. For those keeping score, a lot of the Vibrant’s perfectly serviceable features are back. So, what’s new? Android 2.2, for starters. Also, as the phone’s awkward moniker boasts, this handset bri...

It's an exciting time to be a T-Mobile customer. There's never been a better selection of high-end AWS-compatible Android devices before. The Galaxy S 4G, Nexus S, myTouch 4G, and G2 each bring a unique flavor of Android to the table. We think "pure" Android 2.3 trumps HSPA+, so the Nexus S is our f...

The Samsung Galaxy S 4G ranks in the 'Average' category. While the original Samsung Vibrant was a breath of fresh air to a stagnant T-Mobile line up, the Galaxy S 4G actually acts as a bit of an insult to T-Mobile customers. It hasn't even been a full year yet, meaning customers who bought the Vibra...

The Samsung Galaxy S 4G worked really well for the first week or so. I was impressed with how stable and improved it was compared to the previous Samsung Galaxy S Vibrant. Unfortunately, after I installed literally two apps (Google Maps' update and, force quit error dialogs started ap...
