Android 15 introduces true variable refresh rate support, but there are limitations
Android 15 Brings True Variable Refresh Rate (VRR) Support
Most modern Android smartphones, including mid-range and flagship devices, come equipped with high-refresh-rate displays. These screens often operate at fixed rates like 60Hz, 90Hz, or 120Hz. Even some budget phones now feature refresh rates above the standard 60Hz. However, while many phones boast this feature, they lack true variable refresh rate (VRR) technology. Despite manufacturers marketing VRR support through LTPO (Low-Temperature Polycrystalline Oxide) displays, Android itself didn’t fully support VRR until the release of Android 15.
What Is Adaptive Refresh Rate in Android 15?
With Android 15, Google has introduced Adaptive Refresh Rate (ARR), a form of VRR, directly into the operating system. Previously, Android could switch between different fixed refresh rates like 60Hz and 90Hz based on the display mode. However, this was not a true adaptive system. The operating system would switch modes based on content but couldn’t seamlessly adjust refresh rates within a single mode.
In Android 15, ARR dynamically adjusts the refresh rate according to the content’s frame rate without needing to change display modes. This ensures a smoother user experience by adapting the screen refresh rate on the fly, whether you’re watching a video or playing a game.
Benefits of True Variable Refresh Rate in Android 15
Google highlights two main benefits of the ARR feature in Android 15:
- Power Efficiency: By allowing the display to operate at lower refresh rates when high refresh rates aren’t necessary, the device consumes less power. It ramps up the refresh rate only when the content requires it, reducing unnecessary battery drain.
- Improved Performance: Since ARR eliminates the need to switch between different display modes, it reduces potential “jank” or stuttering issues that occur during mode transitions, offering a smoother visual experience.
Why Wasn’t True VRR Supported Before?
Although smartphone manufacturers have promoted variable refresh rate features with LTPO displays, these implementations were limited. LTPO displays allowed for a broader range of refresh rates, from as low as 1Hz or 10Hz up to 120Hz. However, this was achieved by toggling between fixed display modes rather than dynamically adjusting within a single mode.
For example, on many Android devices with LTPO OLED panels, the refresh rate could drop to 10Hz during static content like reading, then jump to 120Hz during gaming. However, these changes were still tied to pre-defined modes and didn’t dynamically adapt based on real-time content needs, unlike true VRR seen in PC gaming monitors.
Technical Advancements in Android 15
In previous Android versions, some OEMs tried to implement VRR-like features at the kernel level. However, this approach required custom logic for each device, making it difficult to standardize due to Android’s Generic Kernel Image (GKI) requirements. The kernel, responsible for managing hardware, lacked deep insights into the content being displayed, limiting its ability to adjust the refresh rate effectively.
Android 15 addresses this by implementing VRR at the Hardware Composer (HWC) HAL (Hardware Abstraction Layer) level, specifically with the introduction of version 3 of HWC HAL APIs. This allows the operating system to make more informed decisions about when to adjust the refresh rate based on the content displayed. It offers a unified method for OEMs to implement adaptive refresh rates without needing complex customizations at the kernel level.
Device Compatibility and Challenges
While Android 15 introduces true VRR support, not all devices will be able to use it right away. For a phone to take advantage of this feature, it must have support for the updated HWC HAL version 3. Currently, devices like the Google Pixel 7 and newer models, as well as those powered by the Qualcomm Snapdragon 8 Elite chip, have this version. However, older devices, including the Google Pixel 6 series and phones using the Qualcomm Snapdragon 8 Gen 3, do not support the necessary HAL version.
Additionally, even if a device receives an update to Android 15, it may not support ARR due to hardware limitations or the effects of Google’s Requirements Freeze (GRF) program. This program prevents mandatory hardware changes in updated devices, so phones designed before the release of HWC HAL version 3 may not fully support Android 15’s adaptive refresh rate features.
Future Impact and Expectations
If Android 15’s adaptive refresh rate feature is widely adopted, it could lead to better performance and battery efficiency in everyday use. For instance, it may help devices reduce the refresh rate to 30Hz or 24Hz when playing films, rather than defaulting to 60Hz, which could conserve battery life.
However, it’s important to note that Android 15’s implementation is not the same as the true VRR seen in gaming PCs, where the refresh rate matches the frame rate of the game. Instead, Google’s documentation indicates that the adaptive refresh rate in Android 15 only supports rates that are divisors of the display’s native refresh rate to prevent tearing effects.
This means that while Android 15’s ARR feature offers significant improvements, it may not provide full synchronization between game frame rates and display refresh rates, as seen in PC monitors with NVIDIA G-Sync or AMD FreeSync.
Looking Forward
As more details emerge and updates roll out, it will be interesting to see which existing devices fully adopt Android 15’s adaptive refresh rate capabilities. Google’s future Pixel devices are likely candidates for early adoption, but broader support will depend on how quickly OEMs implement the necessary hardware and software changes.
In conclusion, Android 15 marks a significant step forward in providing true VRR support at the operating system level. While the feature is promising, its real-world impact will depend on device compatibility and OEM adoption. Users can look forward to a smoother experience and potentially better battery life, making it a long-overdue but welcome addition to the Android ecosystem.

New Android Gesture: Addressing the Loss of Home Button Shortcut
With recent updates, Google introduced Circle to Search, a feature that allows users to quickly search content by long-pressing a gesture button or the home button. However, this change removed a widely used method to invoke the default assistant by long-pressing the home button.
To resolve this, Google is developing a new gesture specifically designed for devices using the traditional three-button navigation system.
- Gesture Invocation Options:
- Android provides several ways to access the default assistant, such as using voice commands like “Hey Google” or “Hi Bixby,” pressing the power button, or swiping up from the bottom corner on gesture navigation devices.
- Issue with Circle to Search:
- When Circle to Search was introduced, it took over the long-press action of the home button. Disabling Circle to Search does not restore this function, making it impossible to use the home button for assistant access in the three-button navigation mode.
- New Gesture in Development:
- In the Android 15 QPR1 Beta 3, Google is testing a new corner swipe gesture for three-button navigation. This gesture allows users to swipe diagonally from the left or right bottom corner to invoke the assistant, similar to the existing gesture navigation system.
- Although this feature is not yet available in the public beta, it has been tested internally and is expected to roll out soon.
- Possible Rollout and Adoption:
- This new gesture might be included in the second quarterly platform release of Android 15, with a potential toggle option similar to other navigation gestures.
- Some manufacturers like OnePlus are already ahead, implementing their own version of this corner swipe gesture in OxygenOS 15, indicating a trend towards faster adoption across Android devices.
Conclusion
With the wider rollout of Google Home Gemini Extension and the development of a new gesture to simplify assistant access, Google is actively enhancing user experience. The extension offers improved smart home control, making interactions with devices more intuitive and conversational. At the same time, the new Android gesture aims to resolve user frustration caused by the removal of the home button shortcut, providing a seamless experience across different navigation modes.
Overall, these updates showcase Google’s commitment to refining its ecosystem, making it more user-friendly and integrated with modern smart home setups. Keep an eye out for these features as they continue to expand and roll out across Android devices.
