Easy or advanced ways to check UFS version in a phone

Last updated: 2026-09-02

Welcome to Blackview (Well-known brand of military grade smartphone and tablet) blog. Hope the guide helps.

Universal Flash Storage (UFS) is one of the most important storage technologies used in modern smartphones. It affects how quickly your phone can read and write data, install applications, load games, process large files, and perform demanding background tasks. Different UFS generations, such as UFS 2.1, UFS 2.2, UFS 3.0, UFS 3.1, and UFS 4.0, can offer significantly different performance and efficiency. However, manufacturers do not always display the UFS version in the phone's normal settings, which makes identifying it less straightforward than checking RAM, processor, or display specifications.

Fortunately, there are several ways to determine which UFS version your phone uses. You can start with the manufacturer's official specifications, check a detailed hardware-information application, inspect Android system information, or use benchmark results as supporting evidence. The most reliable method depends on your phone model and how much technical information the manufacturer exposes. This guide explains each approach, how to interpret the results, and how to avoid confusing UFS storage with other specifications such as storage capacity, eMMC, or the type of RAM installed in the device.

Method 1: Check the manufacturer's official specifications

The simplest and usually most reliable approach is to look up your exact phone model on the manufacturer's official website. Some manufacturers explicitly list the storage technology and UFS generation in their technical specifications. Others only provide storage capacity and read/write performance, so the UFS version may need to be confirmed elsewhere.

Steps to find the specification

• Open the phone manufacturer's official website.
• Search for your exact phone model and regional variant.
• Open the product's detailed specifications page.
• Look under Storage, Memory, Hardware, or Specifications.
• Search for terms such as UFS 2.1, UFS 3.1, or UFS 4.0.
• Check whether the listed storage technology applies to your exact storage configuration.

This last point is important because the same phone family can sometimes have different storage configurations depending on region, capacity, or manufacturing batch. A specification for one variant should not automatically be assumed to apply to every version of the device.

Method 2: Use a hardware-information app

When the manufacturer's specification does not mention UFS, an Android hardware-information application can often reveal more details about the internal storage. These applications read information exposed by the operating system and hardware interfaces and can display storage-related parameters that are not visible in the standard Settings application.

Steps to check UFS information

• Open the Google Play Store on your Android phone.
• Search for a reputable hardware-information application.
• Install the application and open it.
• Navigate to the Storage, Memory, or Hardware section.
• Look for entries containing UFS, Universal Flash Storage, or a storage-device identifier.
• Record the reported UFS generation and compare it with the manufacturer's specifications.

Applications may identify the underlying storage device by model number rather than directly saying "UFS 3.1" or "UFS 4.0." If that happens, search the exact storage-device model number in reliable technical documentation. Do not assume that an application's generic "flash storage" label automatically identifies the UFS generation.

Method 3: Check Android system information with ADB

More technically experienced users can investigate storage information through Android Debug Bridge (ADB). This method can expose system-level information that ordinary apps may not show. However, Android versions and manufacturer software differ, so the exact output is not guaranteed to contain a clear UFS version.

Steps for an ADB-based check

• Enable Developer options on your Android phone.
• Enable USB debugging inside Developer options.
• Install ADB tools on a computer.
• Connect the phone to the computer using a USB cable.
• Accept the USB debugging authorization prompt on the phone.
• Use ADB to inspect available storage and system information.
• Look for storage-device names, paths, or hardware identifiers that can identify the underlying UFS component.

ADB is best considered an advanced diagnostic method rather than a guaranteed one-click UFS detector. Some manufacturers restrict hardware information, and newer Android security mechanisms can limit what can be read without additional privileges. You should also avoid changing system partitions or running commands you do not understand simply to obtain the storage version.

Method 4: Identify the storage chip model

If your phone does not directly report its UFS generation, identifying the physical storage component can provide another route. Smartphone storage chips have manufacturer part numbers and model identifiers. Once the exact component is identified, its technical documentation can reveal whether it belongs to a UFS 2.x, 3.x, or 4.x generation.

Steps for identifying the chip

• Use a trusted hardware-information tool to obtain the storage-device model number.
• Write down the complete model or part number.
• Search for that exact identifier in reputable semiconductor or technical databases.
• Confirm that the component is intended for UFS storage.
• Check the component's interface generation and published specifications.
• Compare the result with your phone's exact model and storage capacity.

This method can be especially useful when a phone manufacturer uses different storage components across production runs. However, hardware identification is more complicated than simply reading a label, and incomplete databases can sometimes produce misleading results.

Method 5: Use benchmark results as supporting evidence

Storage benchmarks can help determine whether a phone's storage performance is broadly consistent with a particular UFS generation. Sequential read and write speeds, random access performance, and application-loading behavior can provide useful clues. However, benchmark performance alone cannot prove the exact UFS version.

How to interpret benchmark evidence

• Run a reputable storage benchmark under normal conditions.
• Record sequential read and write results.
• Compare the results with other devices using known UFS generations.
• Run multiple tests if the results appear unusually inconsistent.
• Use benchmark data only as supporting evidence rather than definitive identification.

Actual performance depends on many factors, including storage capacity, controller design, thermal conditions, firmware, free storage space, workload, and power-management settings. Consequently, a benchmark score that resembles UFS 3.1 does not necessarily prove that the phone contains UFS 3.1 storage.

How to avoid common UFS identification mistakes

Several specifications are frequently confused with UFS. Storage capacity, for example, describes how much data the phone can hold, while UFS describes the storage technology and interface. A 256 GB phone is not automatically faster or slower simply because of its capacity. Similarly, LPDDR4X, LPDDR5, and LPDDR5X refer to RAM technology, not internal storage.

UFS version versus storage capacity

UFS 3.1 can be available in multiple capacities, and the same is true for other generations. Therefore, "256 GB" tells you how much storage is available but does not identify its UFS version.

UFS versus eMMC

UFS and eMMC are different storage standards. Older or entry-level smartphones may use eMMC, while many modern mid-range and flagship phones use UFS. If a specification says only "flash storage," additional verification is necessary before assigning a UFS generation.

Which method is the most reliable?

For most users, the best strategy is to combine two sources. First, check the manufacturer's official specifications for the exact model and storage variant. If the information is missing, use a reputable hardware-information tool to identify the storage device. If both sources agree, you can have considerably more confidence in the result.

Recommended verification order

• First: Check the official specifications for your exact phone variant.
• Second: Use a hardware-information application to inspect the storage details.
• Third: Identify the storage chip or device model if necessary.
• Fourth: Use ADB for additional system-level information.
• Finally: Treat benchmark performance as supporting evidence only.

Final four things to check after identifying your UFS version

1. Confirm the exact phone variant

Check the model number, region, RAM configuration, and storage capacity before comparing your result with online specifications. Different variants can sometimes use different components.

2. Check available free storage

Even fast UFS storage can perform poorly when the phone is heavily loaded or nearly full. Keep sufficient free space available for Android and applications to operate efficiently.

3. Compare real-world performance

UFS generation is useful for understanding hardware capability, but everyday performance also depends on the processor, RAM, software optimization, thermal management, and storage controller.

4. Use multiple sources before drawing a conclusion

No single third-party application should automatically be treated as definitive. Cross-check the reported information against official specifications and reliable technical documentation whenever possible.

Conclusion

Checking your phone's UFS storage version can require more investigation than checking ordinary specifications, because many manufacturers do not display the information directly in the Settings menu. The official product specification is the ideal starting point, while hardware-information apps, storage-device identifiers, ADB, and benchmark results can provide additional evidence when the official information is incomplete.

For the most accurate result, identify your exact phone variant first and then verify the storage technology using at least one reliable independent source. Once you know whether your phone uses UFS 2.x, UFS 3.x, UFS 4.x, or another storage standard, you can make more meaningful comparisons when evaluating performance, upgrading to a new phone, or troubleshooting storage-related issues.
