Samsung Galaxy S6 Duos

Do you want to sell or trade your Samsung Galaxy S6 Duos?


Yes? Good, you’re at the right place.


But first, I need you to determine if you want to trade your phone for a better version, or if you want to sell it for cash?  


After you decide, we’ll walk you through the steps to cash in or trade up.

In the meantime, let’s review your phone. 


Build & Design 

After years beckering consumers, Samsung finally decided to make their flagship phones look as good as they performed. They accomplish this by simply replacing the plastic back with glass. This instantly gave the Galaxy S6 platform a huge boost in the looks department. They also polished the metal frame and flatten the sides. Not only does it provide more surface grip, but it also feels good in hand. These little changes made the S6 very comparable to the iPhone 6. In fact, they look like they could be brothers. While the phone is strikingly handsome, it didn’t come without cost. Samsung had to sacrifice a few key features to get the stunning phone you see before your eyes today.


One sacrifice is that the user can’t remove the phone’s back cover, rendering the 2550 mAh battery non-removable. But that’s the least of our concerns. Our biggest gripe is not having the option for expandable storage. That’s right … There’s no microSD card slot. But having the storage option of 32, 64, or 128GB to choose from lessened the impact quite a bit.


Taking one look at the phone, you can tell this is one high-quality device. It’s running a Super AMOLED display, which has excellent viewing angles. No matter where you are—indoors or outdoors—the 5.1-inch Quad HD has perfect visibility. The resolution is 2560 x 1440 pixels and the pixel density is 577 PPI. It’s definitely the best screen in class. And it still rivals any display you can find on the market today.


What makes the Samsung Galaxy S6 Duos stand out above other S6 models is the ability to have two SIM cards. Some major benefits of having two SIM cards is that you can have multiple coverage and two distinct phone numbers. Therefore, you can keep work and play separate with full coverage. If you travel internationally, the S6 Duos can really come in handy. You can have one domestic SIM card and another one for travel purposes.


Other external features include a micoUSB connector, 3.5 mm audio jack, and speakers on the bottom as well as an IR blaster sensor on top. On the right, there’s a power key. And on the left, there’s volume keys. The camera lens sits in the back of course. And the front has a physical home button/fingerprint scanner and two capacitive keys: recent apps and back key.



The Galaxy S6 Duos has many sensors. There’s an IR blaster sensor, a heart rate sensor, a UV sensor, and an accelerometer. There’s also a barometer, fingerprint sensor, and a proximity sensor. This all operates under Android 5.0.2 Lollipop, which now can be updated to Android 8 Oreo.


The UI is TouchWiz custom skin that’s similar to Google’s Material Design. Samsung got rid of the access bloatware in favor of a more simple clean look. Some features include Google Now on Tap, S Health, S Planner, and S Voice. There’s also Samsung’s Smart Manager, Samsung’s Galaxy App, Microsoft’s OneDrive, and OneNote apps.


Multitasking has been made easy. You can split the screen between two applications and even exchange data between them. For example, email and gallery.


The OS is powered by the Exynos 7420 processor. It’s an 8-core CPU that uses ARM’s big.LITTLE technology. That is four cores for high-intensity tasks and four cores for mild tasks. This in combination with the 14nm and 3GB of RAM makes the S6 Duos very power efficient and wickedly fast for its time.


On the Geekbench 5 test, the S6 Duos scored a 227 on the Single-Core test and an 891 on the Multi-Core test. For comparison, the Galaxy S21 Ultra scored 1123 and 3440. And the iPhone 12 Pro Max scored 1600 and 4100.


With the S6 Duos, you get one rear 16 MP camera with a wide f/1.9 aperture lens. Some notable features include Optical Image Stabilization, HDR, virtual shot, time-lapse, and slow-motion.


The quality of the photos are bright and vibrant with plenty of fine details. OIS and HDR works like a charm. In particular, the HDR balances photos without compromising or losing the integrity of the photo.


If you’re looking for a flexible, insanely fast phone that can take Facebook worthy pictures, the Samsung Galaxy S6 Duos is an excellent and affordable option.
