The iPhone 6s innovated with a feature that until then had not appeared on any smartphone (except for the Huawei Mate S released shortly before), which was pressure detection on the screen. Reading pressure levels It opened the door to new interactions and shortcuts. Whether it truly represents the future of mobile devices and is genuinely useful remains to be seen, but it appears unlikely to be included in the launch of the new Android N operating system.
There are already mobiles with this technology
There are Android phones that already have pressure detection technology similar to the iPhone's 3D Touch. The Huawei Mate S It's one of those cases, for example, and it was launched even before Apple's phone. But there are more cases. Up to Meizu It has its own technology, mPress. Because of all this, we believed, and it seemed clear, that Android N, the new version of the operating system that will be released, would feature a similar pressure-sensing technology on the screen. This technology would actually be part of a Common API for manufacturers that manufacturers could use, being common to all Android phones, and with Google offering this technology to manufacturers, which would save them a lot of work, and ensure that the quality of this technology would be as expected.
However, it seems that Android N will not be included when it launches with this technology. At least, that's what the latest information tells us. It is believed that it could receive a future update which would include this technology. In other words, there would be no need to wait for a major new version; a maintenance update would be released that adds this feature. In any case, this isn't great news for Android, nor for manufacturers, who will have to decide what to do: continue working on their own technologies and later integrate Google's, or simply forgo the technology until Google integrates it natively into Android. Meanwhile, the iPhone 7 is already preparing for its launch in the second half of this year. Undoubtedly, this is a problem for both the operating system and the manufacturers.
How can pressure detection work without dedicated hardware?
Beyond the purely physical approach, Google has explored a path based on automatic learning to recognize firm heartbeats without specific sensors. touch panels they consist of rows and columns of electrodes which form small capacitors. Although these cells do not directly measure “force”, they do respond very accurately to variations in distance and contact area of the finger.
When we press harder, the finger flattens its surface more and "occupies" a larger area in the tactile matrix. From this pattern, a neural network It can classify whether a press is normal or intense. In practice, the system detects the "press" gesture (similar to flipping a switch) and processes it. real time so that there is no noticeable latency. This simulates a feeling of "pressure" through software, without the need for specialized hardware, improving the touch sensitivity in some cases.
Android Shortcuts, Deep Press, and the Role of Software
The Android N previews introduced the Launcher ShortcutsShortcuts for executing frequent actions from the desktop. Developers like Kevin Barry (Nova Launcher) attempted to implement them following the early documentation and found that, rather than individual icons, they would be more like... gestures on the iconThis fits with the idea of ​​distinguishing firm pulses for accelerate the long pulse and display context menus, even if there is no physical pressure sensor.
Google then described the gesture of Deep Press as a way to "press harder" to trigger actions that traditionally required holding down the button. This approach would allow phones without dedicated sensors to benefit from the experience. The proposal has clear advantages: Pressure sensors are expensive and complex to integrate, and the software solution unifies behavior at the system level without forcing each manufacturer to create its own path.
What are manufacturers and the community doing?
While a fully native and standardized support is still pending, the Android ecosystem has explored multiple avenues. Synaptics, a provider of touch controllers, introduced its technology. ClearForce to distinguish different pressure levels and added features such as tactile edges or touchless finger detection. Meanwhile, some OEMs registered trademarks such as “4D Touch” Exploring evolutions on the classic 3D Touch, although without definitive public details.
The development community has also contributed alternatives, with modules for Xposed It was possible to map “firm presses” to actions such as long presses or swipe combinations, and even distinguish between knuckles and fingers due to area differences. These are advanced solutions that require root access and don't work uniformly across all models, but they demonstrate that the software can replace a large part of the experience.
Advantages, limitations, and user experience
The biggest benefit of touch pressure on Android would be reducing steps: opening ShortcutsThis would allow developers to preview content or access context menus without navigating through multiple screens. Furthermore, if Android standardizes the API, developers will be able to adopt this feature. consistent in their apps.
Among the challenges, the following stand out: fragmentationDifferent manufacturers, panels, and system versions make a consistent experience difficult. There is also a learning curveGestures must be discovered and remembered by the user. That's why Google is exploring alternative approaches such as multi-finger gestures or visible shortcuts that do not depend solely on the force applied in touchscreens.
For manufacturers, the decision hinges on whether to pursue their own implementation (hardware or software) or wait for Google to consolidate the API pressure and the launcher shortcuts. For users, the goal is clear: faster interactions, without sacrificing latency nor precision.
The combination of Android shortcuts, machine learning detection, and OEMs' prior experience with pressure-sensing solutions paints a picture where the "third dimension" of touch could mature without the need for dedicated sensors. If Android N doesn't incorporate this feature, all signs point to the ecosystem continuing to evolve to offer firm pulses more useful, consistent, and widely available.
