The Pro 91 does not receive Phase 2 updates
The Pro 91 reached end of support in 2022 and is no longer included in the Phase 2 update cycle. Phase 2 updates are reserved for current-generation devices that meet the manufacturer's active support requirements. If you own a Pro 91, you will continue to receive security patches through the standard maintenance window, but you will not move forward to Phase 2 features or architectural changes.
This is a common point of confusion because the Pro 91 was a capable device when it was current. The shift away from Phase 2 support is not about performance — it is about the device's age relative to the manufacturer's support timeline. Once a device exits the active support window, it stays on its current phase indefinitely unless the manufacturer reverses that decision, which is rare.
Key Takeaways
- The Pro 91 stopped receiving Phase 2 updates when it reached end of support in 2022.
- You will still get security patches on your current phase, but no new Phase 2 features or system architecture changes.
- The Pro 91 can continue to function normally for most everyday tasks, but it will fall further behind as newer phases introduce compatibility changes.
- If Phase 2 features matter to your workflow, you would need to move to a device that is currently in the active support window.
What Phase 2 actually includes
Phase 2 is not just a version number bump. It includes architectural changes to how the system handles memory, processes updates, and manages background tasks. These changes often require hardware capabilities that the Pro 91 either lacks or has in limited form. The manufacturer tests Phase 2 on devices with specific processor generations, RAM configurations, and storage types — the Pro 91 does not meet those baselines.
Phase 2 also introduces new security protocols that can be resource-intensive on older hardware. Running these protocols on a Pro 91 would create performance problems that would frustrate users more than the lack of Phase 2 itself. The manufacturer's decision to exclude the Pro 91 is partly about preventing a bad experience on hardware that cannot handle the new architecture smoothly.
When the Pro 91 stops getting security patches
Security patches are different from Phase 2 updates. Your Pro 91 will continue to receive patches for vulnerabilities discovered in its current phase, but only for a set window. That window typically extends 18 to 24 months past the end-of-support date, which means the Pro 91 should receive patches through late 2023 or early 2024, depending on when the manufacturer declared end of support.
After that window closes, no new patches will be released for the Pro 91, even if vulnerabilities are found. At that point, the device becomes a security risk for tasks that involve sensitive information — banking, email, or work accounts. You can still use it for offline tasks or low-risk activities, but connecting it to the internet for anything important becomes a real exposure.
Devices that do receive Phase 2 updates
Phase 2 support is available for devices released within the last three to four years, depending on the manufacturer's support policy. The Pro 95, Pro 97, and the newer Pro 100 series all receive Phase 2 updates. If you are considering an upgrade, check the manufacturer's support timeline for any device you are looking at — it will tell you how many years of Phase 2 updates you can expect from the purchase date.
Some manufacturers publish their support roadmap publicly, which shows which devices are in Phase 1, Phase 2, and extended support. If you cannot find that information on the manufacturer's website, contact their support line directly and ask for the support status of a specific model. They can tell you the exact end date for Phase 2 updates and when security patches will stop.
What you can do with a Pro 91 now
A Pro 91 is still usable for most everyday tasks — email, web browsing, document editing, media playback. The lack of Phase 2 updates does not mean the device stops working. It means you are not getting new features, and eventually you will not get security patches. For personal use on a home network, that may be acceptable. For work or for handling financial information, it becomes riskier over time.
If you want to keep using your Pro 91, treat it as a device for low-risk tasks only. Do not use it for banking, shopping, or work email once the security patch window closes. Keep it on your home network rather than using it on public WiFi. And do not install software from untrusted sources, since you will not be able to patch vulnerabilities that the software might introduce.
How to check your device's support status
You can find your device's support status on the manufacturer's website. Look for a page labeled "Support Status", "Device Support", or "Software Updates". Enter your device model number (for the Pro 91, that is usually printed on the back or found in Settings under Device Information). The page will show you the current phase, the end date for Phase 2 updates, and the end date for security patches.
If you cannot find that information online, you can also check within the device itself. Go to Settings, then About Device or System Information. Look for a field labeled "Support Status" or "Update Status". Some manufacturers show the support timeline right there. If it says "End of Support" or shows a date in the past, your device is no longer receiving Phase 2 updates.
Frequently Asked Questions
Can I manually install Phase 2 on my Pro 91?
No. Phase 2 is not a file you can download and install. It is a system architecture that requires specific hardware capabilities. The Pro 91 does not have the processor, memory, or storage architecture that Phase 2 requires, so even if you had the Phase 2 files, the device could not run them.
Will my Pro 91 stop working if it does not get Phase 2?
No. Your Pro 91 will continue to work on its current phase indefinitely. You will not get new features, and eventually security patches will stop, but the device itself will not become unusable just because Phase 2 is not available.
Is it safe to use a Pro 91 after security patches stop?
It depends on what you use it for. For offline tasks or low-risk activities on a home network, it is reasonably safe. For banking, email, or work, it becomes a security risk because vulnerabilities will not be patched. If you handle sensitive information, you should move to a supported device.
How much longer will the Pro 91 get security patches?
That depends on when the manufacturer declared end of support. Most manufacturers provide patches for 18 to 24 months after that date. Check the manufacturer's support page or contact their support team to find the exact end date for your Pro 91.
What should I do if I want Phase 2 features?
You would need to move to a device that is currently in the active support window. The Pro 95, Pro 97, and Pro 100 series all receive Phase 2 updates. Check the manufacturer's support timeline before you buy to see how many years of Phase 2 support you will get from the purchase date.
