Determining the UFS Version on Galaxy S8/S8+ Devices

Samsung has seemingly followed Huawei’s approach with their flagship devices, P10 and P10 Plus, in creating a hardware lottery for their Galaxy S8/S8+ models.

Like Huawei’s devices, Samsung’s offerings may feature any combination of LPDDR3 or LPDDR4 for RAM and eMMC 5.1, UFS 2.0, or UFS 2.1 for storage. This variability makes it difficult for consumers to know what combination they have purchased.

In this post, we will guide you through the process of determining whether your Galaxy S8/S8+ is equipped with UFS 2.0 or UFS 2.1.

Evaluating UFS 2.0 or UFS 2.1 in Galaxy S8/S8+

Previously, Samsung had emphasized the inclusion of UFS 2.1 in the Galaxy S8/S8+ in their promotional materials.

However, some people noticed that these mentions have been discreetly removed, suggesting that the devices could feature either UFS 2.0 or UFS 2.1. This claim is supported by reports of varying sequential read speeds among Galaxy S8/S8+ devices, with UFS 2.1 models reaching speeds around 800 MBps and UFS 2.0 models achieving 500-600 MBps.

While this difference may not significantly impact daily usage, consumers deserve to know which version they have, especially since Samsung initially advertised UFS 2.1. Here are two methods to identify whether your Galaxy S8/S8+ is equipped with UFS 2.0 or UFS 2.1.

Method 1: Identifying UFS Version in samsung Galaxy – Using Terminal Emulator

1. Download and install the Terminal Emulator app on your device.
2. Launch Terminal Emulator and enter the command “cat /proc/scsi/scsi.”
3. This command will return the precise model number of your memory chip. If the model number is ‘THGAF4G9N4LBAIRB,’ your device features UFS 2.1. If the model number is ‘THGBF7G9L4LBATRC,’ your device is equipped with UFS 2.0.

Method 2: Determining UFS Version of Samsung Galaxy Through Sequential Read Speeds

1. Use the AndroBench app to measure your device’s sequential read speeds.
2. If the speeds fall within the 700-800 MBps range, your device is likely to have UFS 2.1. If the speeds are between 500-600 MBps, your device likely features UFS 2.0.

We encourage you to share your findings in the comments section. Let us know whether your Galaxy S8/S8+ has UFS 2.0 or UFS 2.1.
