Yes—Razer’s Kishi Ultra is one of the most broadly compatible wired mobile controllers available. It officially supports USB-C iPhone 15 and 16 models, Android 12-or-later devices, selected iPad mini models, Android tablets up to 8 inches, and Windows 11 PCs. It can also work with at least some foldable phones, including a Samsung Galaxy Fold reported by Windows Central.
But “works with damn near everything” is not a universal guarantee. A device must physically fit, align with the controller’s integrated USB-C connector, expose a compatible operating-system connection, and run a game that accepts controller input. Foldable phones make every one of those conditions more complicated.

Razer’s support documentation and product page are the best places to check platform requirements. The named Android phones—including Samsung Galaxy S23 models, Google Pixel 6 through 8 families, and the Razer Edge—are examples rather than a complete list.
What the Kishi Ultra officially supports
USB-C iPhones
The Kishi Ultra is designed for USB-C iPhones, specifically the iPhone 15, 15 Plus, 15 Pro, 15 Pro Max, iPhone 16, 16 Plus, 16 Pro, and 16 Pro Max. It is not a universal iPhone controller: older Lightning models are outside this official compatibility claim.

- POWERED BY THE RAZER NEXUS APP — Launch games, customize controls, record and share gameplay, and keep the Kishi Ultra updated with the Razer Nexus App that can be brought up at the touch of a dedicated button
Android phones
Razer specifies Android 12 or later. That requirement is necessary but not sufficient. The phone also needs a suitable USB-C implementation, a correctly positioned port, and dimensions that allow the controller to close around it.
iPad mini and Android tablets
The officially supported Apple tablets are the sixth-generation iPad mini and the iPad mini with A17 Pro. Razer also lists Android tablets up to 8 inches. That does not mean every 8-inch tablet will fit: the relevant measurements are the device’s actual length, thickness, port position, and case geometry.
Windows 11 PCs
The Kishi Ultra can function as a Windows 11 controller through USB-C. Because it is wired, PC use requires a separate USB-C cable; it does not simply pair wirelessly with a computer. Razer’s launch announcement also describes PC use with haptics and 3.5mm audio.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitchesSome coverage mentions Mac compatibility, but Razer’s reviewed support material specifically documents Windows 11. Treat Mac use as a separate compatibility question rather than an official universal promise.
The physical limits matter more than the phone brand
Razer lists a maximum device length of 210mm (8.3 inches) and a maximum thickness of 13.5mm. The controller uses an integrated USB-C connector rather than a flexible cable, so port alignment matters as much as the headline dimensions.
Removable rubber cushions help the Kishi Ultra accommodate different device thicknesses, and Razer says it works with most popular phone cases. Its USB-C “island” design provides additional depth for cases, including Apple’s first-party cases on larger iPhones. However, a case that covers the port, narrows the USB-C cutout, adds too much thickness, or changes the device’s angle can prevent a connection.

For ordinary slab phones, this is usually a straightforward fit check. For foldables, it is the central buying question.

Pick the symptom - the matching free tool is one click away.
Does the Kishi Ultra work with foldable phones?
Some foldables, yes—but the category is too varied for a blanket guarantee. A Samsung Galaxy Fold has been connected and used successfully in testing reported by Windows Central. That is meaningful evidence that the controller can work with at least some book-style foldables, but it is not the same as Razer certifying every Galaxy Z Fold, Pixel Fold, or flip phone.
Foldables should be evaluated in three configurations:
- Closed: The phone is shorter and narrower, making physical attachment more likely, but the usable screen is smaller.
- Open: The larger display is better for gaming, but the device may become too wide, too thick, or unevenly supported.
- In a case: Hinge protection, thick spines, raised USB-C surrounds, and unusual port cutouts can make an otherwise compatible phone unusable.
Samsung Fold-style phones, Pixel Fold models, and flip-style phones do not present the same physical problem. Port placement, hinge design, folded thickness, open dimensions, and the way the USB-C connector sits against the phone all vary. A report on Reddit describing recognition trouble with a Pixel 9 Pro Fold alongside successful use with a Samsung Z Fold 6 is anecdotal—not definitive proof of incompatibility—but it illustrates why the exact model matters.
Foldable buying checklist
Before ordering, check the following in the configuration you intend to use:
Quick wins for a faster PC:

- Does the closed or open device stay within 210mm in length and 13.5mm in thickness?
- Does the hinge or case prevent the controller from sitting flat?
- Does the case leave enough room around the USB-C port?
- Does the phone remain stable when open, rather than placing excessive sideways force on the connector?
- Can you buy from a retailer with a practical return policy?
If the answer to any physical-fit question is uncertain, a Bluetooth controller with a phone clip is the safer design. It sacrifices the Kishi Ultra’s integrated, low-latency connection but avoids locking a foldable into one rigid position.

Wired USB-C connection: benefits and compromises
The Kishi Ultra draws power from the connected device and does not need its own battery. Direct USB-C avoids Bluetooth pairing and can reduce connection complexity and latency. Pass-through charging lets you charge the phone while playing.
The trade-offs are equally important:
- The controller is wired rather than wireless.
- The integrated connector is less forgiving than a cable.
- The controller consumes some power from the phone.
- The pass-through USB-C port does not support USB-C or Lightning headsets and accessories, according to Razer.
- PC use requires a separate USB-C cable.
There is also a 3.5mm audio jack with microphone support, which is useful when the connected device lacks a convenient headphone connection.
Will every game recognize it?
No. Hardware compatibility and game compatibility are separate questions.
Crashes, No Sound, or Screen Glitches?

Repair common Windows errors and clear accumulated junk for a smoother, more stable PC - no reinstall needed.Free scan · no reinstallA game with native controller support should recognize the Kishi Ultra as a standard gamepad. Cloud gaming and remote-play services are generally strong use cases because their games commonly accept controller input, but support still depends on the specific app and platform. Razer says PS Remote Play works through Virtual Controller on Android and natively on iOS.
For selected Android games without native gamepad support, Razer Nexus offers Virtual Controller Mode. The setup is:
- Attach the Kishi Ultra to the phone or Razer Edge.
- Install and open Razer Nexus.
- Select the game from the Nexus dashboard.
- Toggle Virtual Controller on before launching.
- Launch the game from Nexus.
If the Virtual Controller toggle is unavailable, that game does not support the feature. Touch-only games and games with unusual input systems may still ignore the controller or behave inconsistently. Razer Nexus is not required for basic connection, but it is used for firmware updates, remapping, haptic settings, Chroma configuration, recording controls, dead-zone settings, game discovery, and Virtual Controller Mode. The controller has no onboard memory, so settings are managed through the app.

What makes the Kishi Ultra a premium controller?
The Ultra is built more like a compact console controller than a minimal phone grip. Its feature set includes:
Recommended Free Tools
- Full-size controls.
- Mecha-tactile ABXY buttons and D-pad.
- Hall Effect analog triggers.
- Programmable L4 and R4 multifunction buttons.
- Razer Sensa HD Haptics.
- Chroma RGB lighting.
- 3.5mm audio with microphone support.
- Pass-through charging.
However, the premium features are not platform-neutral. Razer’s launch material says Sensa HD Haptics requires Android 12 or later or Windows 11 and was not supported on iOS or iPadOS at launch. The current product comparison describes haptics as Android-only. Do not buy the controller expecting identical haptic functionality from an iPhone, iPad mini, Android phone, and Windows PC.
Common problems and fixes
The device physically fits but does not connect
Remove the case first and confirm that the USB-C port aligns with the integrated connector. Check the device’s thickness and port position, then test the controller in another known-compatible app. If the problem occurs on a PC, Razer advises ensuring the Kishi Ultra is the only controller appearing in Device Manager.
The game ignores the buttons
- Test the controller in another supported game or app.
- Confirm that the game has native controller support.
- Open Razer Nexus and enable Virtual Controller if the option is available.
- Update the controller firmware.
- Disconnect other controllers that may be taking priority.
- On Android, check whether accessibility or automation tools are interfering.
It works closed but not open
That is physically plausible, not necessarily a software contradiction. Opening a foldable changes its width, thickness, balance, and the relationship between the USB-C port and the controller. Test each orientation separately and avoid forcing the connector.
The controller works but haptics do not
Check the platform, game support, firmware, and Nexus settings. Haptics are subject to Android, Windows, iOS, and iPadOS limitations and are not guaranteed in every title.
Is the Kishi Ultra worth the price?
Razer launched the Kishi Ultra at $149.99 in the United States and €169.99, on April 18, 2024. That is the launch MSRP, not a current guaranteed selling price. Windows Central later reported temporary prices of $69.99 at Amazon and $79.99 at Best Buy in February 2026; those are historical deal signals, not a promise of today’s price.
Best Value
- FULL SIZED CONTROLLER FORM FACTOR — Console performance meets mobile convenience for iPhone* and Android; play for extended periods in complete comfort and control with larger ergonomic handles that feel more natural to hold than standard mobile controllers (*iPhone 15 series and up)
- FULL SIZED TMR THUMBSTICKS — Perfect your aim with high-precision, anti-drift thumbsticks that are superior to Hall Effect designs

(*Razer Nexus does not require a fee/subscription, however some apps within Razer Nexus do)
At the original MSRP, the Ultra makes the strongest case for players who will use its full-size ergonomics, extra buttons, pass-through charging, software features, and broad device support regularly. It becomes substantially easier to recommend below $100, especially if the exact phone or foldable has already been confirmed to fit.
Alternatives worth considering
GameSir G8 Galileo
The GameSir G8 Galileo is the clearest value alternative. GamesRadar praised its lower price, physical fit, and back-button utility compared with the Kishi Ultra. It is a better choice for shoppers who prioritize value over Razer’s Nexus and Chroma ecosystem. Verify its current price separately.
Backbone One
The Backbone One is smaller and more portable, with a mature mobile-focused ecosystem. It is less attractive for large-handed users, larger devices, and anyone seeking full-size console ergonomics.
Razer Kishi V2 USB-C
The Kishi V2 USB-C launched at $99.99 and is the cheaper Razer route. It is more compact, but it does not occupy the same full-size, feature-heavy position as the Ultra.
Bluetooth controller and phone clip
An Xbox Wireless Controller or PlayStation DualSense paired with a separate clip is more flexible for tablets, PCs, consoles, and unusual foldable layouts. It also avoids a rigid connector. The costs are extra bulk, pairing, a separate accessory, and the possibility of more latency than a wired connection.
