The highly anticipated Samsung Galaxy S8 and S8+ have arrived here at iBeta, and have entered service in our mobile testing lab.

The Galaxy S8 offers a 5.8 inch AMOLED screen at 570 ppi, while the Galaxy S8+ has a larger 6.2 inch AMOLED screen at 529 ppi, both at an 18:9 aspect 1440×2960 pixel resolution.

Both phones run Android 7.0 Nougat on an octa-core Snapdragon 835 with 4 GB of RAM and 64 GB of storage, have 12MP rear facing and 8MP front facing cameras, a fingerprint sensor, an iris scanner, and a heart rate sensor, and features both 80.11AC (with gigabit speeds supported) and Bluetooth 5.0 with Near Field Communications (NFC).

We expect that the general need for these phones in test will be for the 18:9 aspect ratio: When displaying 16:9 content, the S8 and S8+ will display black bars to fill the unused space – and while the end-user can change this in the settings, it will effect the image quality. Given the prospective popularity of this phone we are expecting to see a lot of 18:9 content coming soon, and this will make our test phones very busy over the coming months.

The S8 and S8+ have an optional accessory called Samsung DeX, which is mobile-to-PC transition tool that can turn the Galaxy S8 into a PC. Similar to Microsoft’s Continuum feature, the Samsung DeX tool will be compatible with the Galaxy S8 and the Galaxy S8+, and will offer users an Android-based desktop-like experience. Samsung Galaxy S8 users will have to plug the handset into the DeX Station, which will connect the handset to an HDMI compatible monitor as well as connect to any Bluetooth-enabled, USB, or RF-type keyboard and mouse.

For now, DeX — in Android desktop mode — comes with its own browser, and if DeX takes off this may add another browser platform for web-app compatibility sweeps.
