Motorola has begun rolling out Android 16 to its 2025 foldables in the United States, weeks after the software first reached stable channels and days after Google released the first Android 17 beta. The update targets the Razr 2025 and Razr Ultra 2025 (marketed outside North America as the Razr 60 and Razr 60 Ultra) on major US carriers; T‑Mobile and Verizon customers should see notifications shortly if they have not already. Verizon builds are listed as W1UC36H.96-35-1 for the Razr and W1VL36H.59-55-5 for the Razr Ultra. The download is approximately 4GB and will be distributed in staged waves, so arrival timing will vary by carrier and device.
Key takeaways
- Android 16 is being deployed to Motorola Razr 2025 and Razr Ultra 2025 in the US, following Google’s Android 16 rollout in June 2025.
- Carrier targets for the initial push include T‑Mobile and Verizon; Verizon build numbers are W1UC36H.96-35-1 (Razr) and W1VL36H.59-55-5 (Razr Ultra).
- The over-the-air package is roughly 4GB, recommending a fast and stable Wi‑Fi or mobile connection before downloading.
- Rollout is staged: not all eligible devices will receive the update simultaneously, and notification timing may differ by region.
- Devices are marketed as Razr 60 and Razr 60 Ultra outside North America; the update naming aligns with the 2025 model year.
- The release follows days after Google published the first Android 17 beta, underscoring overlapping development cycles for majors and OEM updates.
Background
Motorola returned to the foldable market with the 2025 Razr series, positioning the models as premium clamshell devices with updated hardware and software features. Outside North America they carry the Razr 60 and Razr 60 Ultra names, a distinction that occasionally causes confusion in update tracking and regional support pages. Historically, Motorola has handled major Android upgrades on a carrier-by-carrier basis in the US, which leads to staggered availability and carrier-specific build identifiers for the same handset models. Google released Android 16 to devices in June 2025; OEM and carrier rollout schedules typically follow that launch by weeks or months depending on testing and certification requirements.
Carriers such as Verizon and T‑Mobile run their own validation and pre-deployment tests before authorizing OTA builds for subscribers, which can add delay compared with unbranded or international units. For Motorola’s Razr line, that process produced the specific Verizon build numbers published with this rollout. Users with unlocked devices or models sold outside the US have historically received updates on different timetables; Motorola’s global naming differences (Razr 60/60 Ultra) can make cross-region comparisons tricky. The staged approach aims to limit widespread issues by sending updates first to a subset of devices and expanding distribution if no major problems are detected.
Main event
The immediate development is an over-the-air Android 16 update being dispatched to Razr 2025 and Razr Ultra 2025 handsets on Verizon and T‑Mobile in the United States. Verizon-specific builds have been identified as W1UC36H.96-35-1 for the standard Razr and W1VL36H.59-55-5 for the Razr Ultra, and the package size is reported at about 4GB. Motorol a and carriers will push the update in phases; some subscribers will see a notification within hours while others may wait days as the campaign expands.
Users are advised to back up important data and to download the update over reliable Wi‑Fi or a strong mobile network connection to avoid interruption. As with many staged rollouts, early adopters often act as a de facto test group: fixes to any emergent issues are typically issued in follow-up incremental builds before a full roll out. The update should install through the device Settings menu under System > System update when the push reaches a handset.
This release arrives just days after Google published the first Android 17 beta, a reminder that OEM upgrade pipelines operate on overlapping timelines with platform development. While Android 17 beta availability signals future platform changes, Android 16 remains the current stable upgrade being provided to consumer devices like Motorola’s 2025 Razrs.
Analysis & implications
For Motorola, bringing Android 16 to its 2025 foldables in the US is an important step to keep the devices current and secure, but the timing highlights persistent industry dynamics: platform releases by Google do not instantly translate to OEM or carrier updates. Android 16’s June 2025 public rollout established the baseline, but certification, carrier testing and regional packaging still dictate when a given phone receives the OTA. Users judging a manufacturer solely on speed should account for carrier roles in the US update pipeline.
From a user experience perspective, the 4GB size indicates this is a full platform upgrade rather than a small security patch—expect changes to system-level features, privacy settings and performance optimizations that accompany major Android releases. That said, exact changelog details for Motorola’s build will be most reliable in the official update notes posted by Motorola or the carrier; these notes typically enumerate tweaks, bug fixes and feature availability specific to the device model and region.
Commercially, the update helps Motorola maintain the competitiveness of the Razr 2025 series against similarly priced foldables from other manufacturers. Software longevity and timely major OS upgrades factor into buyer decisions, especially for premium devices. However, the banner that some users will receive Android 16 while Android 17 is already in beta underscores how device support lifecycles and platform development are asynchronous.
Comparison & data
| Device | Carrier (initial) | Build number | Approx. size |
|---|---|---|---|
| Motorola Razr 2025 | Verizon | W1UC36H.96-35-1 | ~4GB |
| Motorola Razr Ultra 2025 | Verizon | W1VL36H.59-55-5 | ~4GB |
The table above captures the confirmed Verizon builds and approximate download size reported for the initial US deployment. Because the rollout is staged, T‑Mobile and other carriers may use different build identifiers or stagger timing; international (Razr 60 / 60 Ultra) units often follow separate schedules and package names.
Reactions & quotes
“If your Razr or Razr Ultra is from T‑Mobile or Verizon, you should be notified about the update very soon, if you haven’t been already.”

“These rollouts are going out in stages, so not everyone will receive the update at the same time.”

“A roughly 4GB download size means users should choose a fast and stable connection before installing.”

Unconfirmed
- Exact timing for when unlocked or non‑Verizon/T‑Mobile US units will receive Android 16 remains unspecified and may differ from carrier-tied schedules.
- The complete changelog for Motorola’s Android 16 builds has not been published in full; feature availability and bug fixes are therefore not fully detailed yet.
- Availability and build identifiers for international Razr 60 / 60 Ultra units have not been confirmed in this initial US-focused rollout.
Bottom line
Motorola’s delivery of Android 16 to Razr 2025 and Razr Ultra 2025 units in the US is a necessary step for keeping those models current, but it arrives on a staggered carrier timetable that means not all users will see the update immediately. The approximately 4GB package and carrier-specific build numbers indicate a substantial platform upgrade that should bring the Razr series in line with Android 16’s security and feature set.
For users: wait for the OTA notification, back up your device, and install over a reliable connection. For observers and buyers: the rollout underscores the reality that stable platform releases from Google and OEM/carrier distributions operate on different schedules—Android 17 beta activity does not prevent carriers from completing Android 16 deployments for supported devices.
