Motorola Razr Ultra (2026) Gets Android 17 in the US: Build A171WLH.38-19-5, 4.17GB
Motorola has started rolling out stable Android 17 to the Motorola Razr Ultra (2026) in the United States. The update arrives as build A171WLH.38-19-5, weighs about 4.17GB and still carries the September 2026 security patch. Owners began reporting it on Tuesday, October 6, and the rollout is staged, so not every US Razr Ultra (2026) will see it at once.
- Build: A171WLH.38-19-5
- Download size: about 4.17GB (some owners see it listed as roughly 4.1GB)
- Security patch: September 2026
- US availability: rolling out in stages since October 6; Motorola has not published a carrier-by-carrier schedule
- How to get it: Settings > System updates > Check for updates
What does Android 17 add to the Motorola Razr Ultra (2026)?
Android 17 on the Razr Ultra (2026) is a visual and notification overhaul rather than a camera or battery update. The most practical change is for the AI Key: a double press can now be remapped, with options that include the Digital Assistant and Motorola's own Qira assistant.
- Notification Summaries condense long messages and busy group chats into a short recap.
- Live Updates get a redesigned, Dynamic Island-style look at the top of the screen.
- Pause Point adds a short delay before distracting apps open, giving you a moment to back out.
- HDR display settings add an intensity slider to brighten and widen color on HDR content.
- Themed icons and a refreshed Settings app with new icons round out the redesign.
Why is the Razr Ultra (2026) still on the September patch?
The Motorola Razr Ultra (2026) Android 17 build ships with the September 2026 security patch, not October's. Google's own phones are already a month ahead: the Pixel October 2026 update carries the 2026-10-05 patch level.
How the Razr Ultra (2026) update compares with the Edge 70
The Razr Ultra (2026) is not the first Motorola phone on stable Android 17. The Motorola Edge 70 received Android 17 in mid-September, and the two builds are close in size and share several headline features, including Notification Summaries, Live Updates, themed icons and HDR controls.
| Phone | Android 17 build | Download size | First reports |
|---|---|---|---|
| Motorola Razr Ultra (2026) | A171WLH.38-19-5 | ~4.17GB | October 6, 2026 (US) |
| Motorola Edge 70 | A17WRH.35-10 | ~4.3GB | September 17, 2026 (AndroidHire report) |
Owners have also reported Android 17 arriving on the Motorola Signature, Edge 60 Fusion and Edge 60 Pro. The Razr Fold has not received it yet, and Motorola has not given a date for it or for other Razr models.
How to install Android 17 on a Razr Ultra (2026)
Motorola sends system updates over the air, but you can check manually. Motorola's US support instructions are:
- Open Settings > System updates. If that entry is missing, go to Settings > About phone > System updates.
- Tap Check for updates.
- If Android 17 is offered, follow the on-screen prompts to download and install it.
Because the file is more than 4GB, download it on Wi-Fi and make sure you have free storage before you start. If nothing appears, the staged rollout has not reached your phone yet; check again over the next few days. Owners of the previous model can compare specs on our Motorola Razr Ultra (2025) page.
