What is confirmed, when you can install it, and who should wait." --- # GrapheneOS Motorola: Signature 27 Costs $1,599, No Install Date **Short answer:** Motorola opened US pre-orders for the $1,599 Signature 27 on November 5, 2026, per 9to5Google. It is the first non-Pixel phone GrapheneOS has committed to support, but it ships with Android 17 and GrapheneOS has no install date. **Takeaway:** The Signature 27 is the first non-Pixel phone headed for GrapheneOS, but buyers who want GrapheneOS should wait for an install date before paying $1,599. **Key figures (as reported by the source):** - US price (512GB / 12GB RAM): $1,599 - Promised OS and security updates: 7 years - GrapheneOS install date: Not announced GrapheneOS Motorola support is real, but it does not come in the box. As of November 6, 2026, the Motorola Signature 27 costs $1,599 in the US for its only US model (512GB of storage, 12GB of RAM), [according to 9to5Google](https://9to5google.com/2026/11/05/motorola-signature-27-specs-price-release-date/). It ships with Motorola's own Android 17, and nobody has given a firm date for when you can put GrapheneOS on it. That still makes the Motorola Signature 27 GrapheneOS story a first. Until this phone, GrapheneOS had only been available on Google's Pixel phones. Motorola is now the only other name on the list of GrapheneOS phones, and the hardware is a flagship: a Snapdragon 8 Elite Extreme Gen 6 chip, a 6.8-inch Tandem OLED screen and a 7,000 mAh battery. So the honest buyer summary is short. You can order the hardware. GrapheneOS, the software it was announced alongside, has no install date yet. If running GrapheneOS is your reason to buy, the rest of this post covers what is confirmed, what is not, and the numbers that matter. ### Does the Motorola Signature 27 come with GrapheneOS? No, the Motorola Signature 27 does not come with GrapheneOS. It ships with Motorola's operating system, Android 17, and Motorola says the phone is "compatible" with GrapheneOS, according to [9to5Google's launch report](https://9to5google.com/2026/11/05/motorola-signature-27-specs-price-release-date/). The GrapheneOS project said the same in its own comments on the [Hacker News thread](https://news.ycombinator.com/item?id=50380810) about the announcement. The phone ships with Motorola's OS. Users will be able to install GrapheneOS themselves on supported devices, and the project promised further announcements. Preinstalled GrapheneOS is a separate question. When the Signature 27 was confirmed as the GrapheneOS phone on September 24, 2026, GrapheneOS said preinstalled devices were "still planned," and it was unclear whether GrapheneOS would be available at launch, [9to5Google reported](https://9to5google.com/2026/09/24/motorola-signature-27-confirmed-to-support-grapheneos/). Nothing in the sources since then changes that. The partnership itself goes back further. GrapheneOS and Motorola first announced they were working together on March 1, 2026, without naming a device. The Signature 27 was named on September 24. Motorola's [newsroom post](https://motorolanews.com/motorola-signature-27-2/) is the primary source to check for the official wording. We did not open it directly, so the price and dates here rest on 9to5Google (single secondary report). ### How much is the Motorola Signature 27? The Motorola Signature 27 costs $1,599 in the US, according to 9to5Google. That price buys the only US configuration: 512GB of storage and 12GB of RAM. There is no cheaper storage tier to step down to. Here is what the money gets you, per the same report: - **Chip:** Snapdragon 8 Elite Extreme Gen 6 - **Screen:** 6.8-inch Tandem OLED, 2772x1272, 120Hz, 12,000 nits peak brightness - **Battery:** 7,000 mAh silicon-carbon cell, 90W wired charging - **Software:** Android 17 with 7 years of OS and security updates (Motorola has not committed to a delivery schedule for them) Pre-orders opened on November 5, 2026, through Motorola.com, Best Buy and Amazon. Motorola.com adds a free Moto Watch Ultra and one year of motocare for a limited time. The Motorola Signature 27 release date in the US is November 19, 2026, according to 9to5Google. Treat that as one outlet's date rather than a settled one: GSMArena has reported November 16, and other reports point to November 26. The pre-order page at the store you use is the place to check the shipping date you will actually get. ![Timeline of GrapheneOS Motorola dates: March 1 deal, November 19 reported release, no install date](/uploads/blog/grapheneos-motorola-signature-27-price-install-date/img1.webp) ### What is GrapheneOS? GrapheneOS is a privacy- and security-focused version of Android built by an open-source project. Until the Signature 27, it was available only on Google's Pixel phones, which is why a flagship from a second maker counts as news. ### What phones support GrapheneOS? The phones that support GrapheneOS are Google Pixel models, with the Motorola Signature 27 as the first non-Pixel device the project has committed to. Future Razr Flip and Razr Fold models are also set to support GrapheneOS, 9to5Google reported in September. Why so few? The [GrapheneOS FAQ](https://grapheneos.org/faq) sets hardware rules for any future device. Two matter most here: - **Hardware memory tagging.** This is ARM's Memory Tagging Extension (MTE) or an equivalent: a chip feature that helps the system detect certain memory-safety bugs. - **Rollback-protected verified boot.** Verified boot checks that the operating system has not been tampered with at startup. Rollback protection stops an attacker from loading an older, vulnerable version. Those rules explain why GrapheneOS supported devices are, for now, Pixels plus one Motorola flagship. On Hacker News, the GrapheneOS account said initial support is limited to flagships because Qualcomm does not offer MTE on its non-flagship chips. The project also said the Signature 27 will meet all of its requirements. Support length is the other filter. The FAQ says Pixel 8 and later get 7 years of GrapheneOS support and older Pixels get 5. GrapheneOS told Hacker News readers the Signature 27 gets 7 years from launch, the same as Pixel 8 and later. If you care about privacy because of what your phone does with your data, our explainer on [on-device AI](/radar/on-device-phone-ai-local-models-apple-android-privacy) covers the other half of that question: which AI features run locally and which send your data to a server. ### When can you install GrapheneOS on the Motorola Signature 27? As of November 6, 2026, there is no confirmed date for when you can install GrapheneOS on the Motorola Signature 27. Outlets have reported a release date for the phone, but GrapheneOS has published no date of its own. That gap is the most important fact for anyone shopping for GrapheneOS phones. What the sources do confirm: - GrapheneOS says users will be able to install it themselves on supported devices (Hacker News comments by the GrapheneOS account). - GrapheneOS says further announcements are coming, with no date attached. - In September, GrapheneOS said it was unclear whether it would be available at launch (9to5Google). So any GrapheneOS Motorola release date you see quoted as fact is a guess until the project publishes one. Watch the GrapheneOS site, since its FAQ is where the supported-device rules live. One practical warning from the [GrapheneOS FAQ](https://grapheneos.org/faq): carrier-locked phones, mainly in the US, may block GrapheneOS installation. Buying an unlocked phone avoids the problem. If you order the Signature 27 for GrapheneOS, confirm the unit is unlocked before you pay. ![Cards showing the Motorola Signature 27 price: $1,599, $3.12 per GB, $228 per year of updates](/uploads/blog/grapheneos-motorola-signature-27-price-install-date/img2.webp) ### SyntaxRadar calculation: the price and the waiting time We ran the numbers from the reported price and dates. Every input comes from 9to5Google or GrapheneOS; the results are our own arithmetic.
What we calculatedInputsResult
Price per GB of storage$1,599 / 512GBabout $3.12 per GB

The per-year figure only holds if Motorola delivers all 7 years of updates, and Motorola has not committed to a schedule. For a GrapheneOS buyer, the last row is the one that matters. The release-date rows also move if GSMArena's November 16 or the later November 26 reports prove right. ### Should you buy now or wait? It depends on why you want the phone. **Buy now if** you want a top-spec Android phone with a long update promise and would be happy running Motorola's Android 17 indefinitely. In that case GrapheneOS is a side benefit, and the Motorola.com pre-order bonus is worth comparing against Best Buy and Amazon. **Wait if** GrapheneOS is the whole point. You would be paying $1,599 for software that has no install date, on a phone whose own release date varies by outlet. Waiting costs you the limited-time watch offer, but it gets you the facts: an install date and the first real-world reports. **Look at a Pixel if** you need GrapheneOS today. Pixel phones are the GrapheneOS phones it already runs on, and Pixel 8 and later get the same 7 years of support the Signature 27 is promised.

GrapheneOS has promised further announcements; the first one that names a date or a build for the Signature 27 answers the question this phone raises. After that, three things to check: - **The real US ship date.** Whether pre-orders arrive on November 19 as 9to5Google reports, or on one of the other dates in circulation. - **Preinstalled GrapheneOS.** GrapheneOS called it "still planned" in September. Any Motorola listing that ships GrapheneOS out of the box would be another first for the project. - **The Razr models.** Future Razr Flip and Razr Fold phones are due to get GrapheneOS support, which would widen the list of GrapheneOS phones beyond Pixels and one Motorola flagship. ## Frequently asked questions ### What is GrapheneOS?
