Samsung Galaxy S27+ May Miss Out on UWB Connectivity, Leak Suggests

Samsung could make an unexpected change to its upcoming Galaxy S27 series by removing Ultra-Wideband connectivity from the Galaxy S27+, according to leaked Chinese certification documents. If the information is accurate, the change would break a feature tradition that Samsung has maintained across its Plus-series flagship phones for several generations.

The reported listings indicate that the Galaxy S27 Pro and Galaxy S27 Ultra include UWB support, while the documents for the standard Galaxy S27 and Galaxy S27+ do not mention the technology.

However, the information remains unconfirmed. Certification documents may not reveal every hardware feature, and Samsung has not announced the Galaxy S27 lineup or its final specifications.

Galaxy S27+ Could Lose a Long-Standing Feature

According to reports covering the Chinese Ministry of Industry and Information Technology (MIIT) certification listings, four upcoming Samsung flagship models have appeared in the database.

The reported model numbers are SM-S9580 for the Galaxy S27 Ultra, SM-S9570 for the Galaxy S27 Pro, SM-S9560 for the Galaxy S27+ and SM-S9520 for the standard Galaxy S27.

The key difference concerns Ultra-Wideband connectivity. The reported documents list UWB support for the Pro and Ultra models but omit it from the Galaxy S27+ and standard Galaxy S27.

The standard model lacking UWB would not be particularly surprising, as Samsung has generally reserved the technology for selected premium devices. The Galaxy S27+ is the more interesting case because Samsung has included UWB in its Plus-series phones since the Galaxy S21+.

If the omission reflects the final retail hardware, the Galaxy S27+ could lose a feature that some Samsung users rely on for locating accessories and interacting with compatible devices.

What Is UWB and Why Does It Matter?

Ultra-Wideband, commonly known as UWB, is a short-range wireless technology that can measure distance and direction between compatible devices with greater precision than conventional Bluetooth tracking alone.

One of its most useful applications is finding supported tracking accessories, including Samsung's Galaxy SmartTag products. With compatible hardware, a phone can provide more precise directional guidance to help users locate misplaced keys, bags and other belongings.

UWB can also support certain digital-key experiences, allowing compatible phones to interact with supported vehicles or smart locks.

Without UWB, a phone may still use Bluetooth to detect nearby accessories, but it could lose some of the precise distance and directional features available through UWB-enabled hardware.

The practical impact depends on the phone's other wireless capabilities and the accessories being used.

Galaxy S27 Pro and S27 Ultra May Retain UWB

The reported certification documents suggest that Samsung could continue offering UWB on its higher-end Galaxy S27 Pro and Galaxy S27 Ultra models.

If these details prove accurate, buyers who regularly use precise tracking features may need to pay closer attention to the differences between Samsung's flagship models.

The Galaxy S27 Pro and Ultra could retain an advantage for users who depend on UWB-compatible SmartTags, digital keys and other supported accessories.

However, the leaked listings do not establish the complete specifications of these phones. Other differences in processors, cameras, battery capacity, displays and pricing remain unconfirmed.

Consumers should wait for Samsung's official announcements before choosing a model based on leaked connectivity information.

Could Bluetooth 6.0 Offer an Alternative?

Bluetooth can already help smartphones detect nearby devices, but newer Bluetooth technology introduces additional capabilities that could improve distance measurement.

Bluetooth 6.0 includes Channel Sounding, a feature designed to enable more secure and precise distance measurement between compatible devices.

If a future Galaxy S27 model supports the required Bluetooth hardware and software, the technology could provide an alternative for certain proximity-based applications.

However, Bluetooth Channel Sounding is not automatically a complete replacement for UWB. The phone, accessory and software must all support the relevant functionality.

Samsung has not confirmed the Bluetooth capabilities of the Galaxy S27 series, so it is too early to determine whether any potential UWB omission would be offset by another technology.

Why Samsung Might Change Galaxy S27+ Connectivity

The leaked documents do not explain why UWB may be absent from the Galaxy S27+.

Possible explanations include hardware changes, differences between regional models or incomplete information in the certification paperwork. None of these possibilities has been confirmed by Samsung.

It would therefore be premature to conclude that the company has deliberately removed UWB to reduce costs or to distinguish the Plus model from the Pro and Ultra versions.

Certification listings provide useful clues about upcoming products, but they do not always reveal the complete feature set of the final devices.

Galaxy S27 Series: What We Know So Far

The reported filings point to a possible four-model Galaxy S27 lineup consisting of the Galaxy S27, Galaxy S27+, Galaxy S27 Pro and Galaxy S27 Ultra.

The documents reportedly confirm cellular connectivity, Wi-Fi and Bluetooth across the listed devices. UWB is mentioned for the Pro and Ultra models but not for the standard and Plus models.

The most notable question is whether the Galaxy S27+ will genuinely ship without UWB or whether the feature is simply missing from the available documentation.

Samsung has not officially confirmed the lineup, the model names or the final specifications. More information is expected as the launch approaches.

Final Thoughts

The possibility of Samsung removing UWB from the Galaxy S27+ could be disappointing for users who rely on precise accessory tracking and compatible digital-key features.

The reported Chinese certification documents point to UWB support on the Galaxy S27 Pro and Ultra, but not on the Galaxy S27 or S27+. Because these details remain unconfirmed, buyers should treat the information as an early leak rather than a final specification.

Samsung's official announcement will ultimately determine whether the Galaxy S27+ loses this feature and whether alternative connectivity capabilities are available.
