The original cover-screen trackpad for foldables — shipping since 2026.
Your foldable's cover screen is facing away from you while the phone is open. This turns it into a rear trackpad: slide a finger on the back, a pointer moves on the main display, tap to click.
A big inner display is awkward one-handed — the far corner is always just out of reach, and stretching for it is how phones get dropped. A pointer solves the reach problem the way it does on a laptop, and the back of the phone is where your fingers already are.
It also does things a touchscreen cannot: precise placement of a text cursor, hovering before you commit, clicking a link the size of a full stop, and a magnifier that follows the pointer.
Why Shizuku? While a foldable is open, Android switches the cover screen off completely and hides it from every app. Shizuku lets Cover Screen Trackpad ask the system to power both panels — the same mode the camera's dual preview uses. There is no way around it, and no other app can grant it. Setting it up takes a few minutes, once.
Not every foldable exposes that mode. Non-Samsung foldables are untested, and some models may not work at all — which is why the app tells you what is missing rather than failing silently.
One payment. No ads, no subscription, no accounts.
Yes, and there is no way around it. While a foldable is open, Android switches the cover screen off and hides it from every app — no permission or setting changes that. Shizuku lets the app ask the system to power both panels, which is the mode the camera's dual preview already uses. It is free, open-source, does not need root, and it is a one-time setup. The setup guide walks through it.
Moving a pointer and clicking on your behalf is only possible through that API — it is the same route any mouse-emulation tool takes. It is a powerful permission and you are right to be careful with it. This app reads window state for exactly one purpose: noticing when a keyboard is open, so edge-click scrolling can be suppressed while you type. Nothing it sees is logged, stored or sent anywhere; it holds no internet permission at all.
Barely. The trackpad surface is pure black and the cover panel is OLED, so almost nothing is lit. Measured on a Flip 6, a running session costs about 4 mA more than simply having the main screen on — below the noise floor of ordinary use. There is also an idle fade-out that ends a session when you stop touching it.
Untested, and honestly uncertain. Everything rests on the phone exposing a mode that powers both screens at once. Samsung foldables do; whether other makers do is an open question we have not been able to answer without the hardware. If you have one and are willing to try, get in touch — the app tells you plainly when the mode is missing rather than failing silently.
Yes. A session ends the moment you start folding, when the screen turns off, when you tap Stop on the notification, or when you swipe the app away — and ending a session hands fold behaviour straight back to the system.
No. The free version is genuinely usable, and PRO is a single payment. No ads, no accounts, no recurring charge.
Cover Screen Trackpad collects nothing. No analytics, no accounts, no network requests, nothing leaves your phone. It has no server to send anything to. Full details in the privacy policy.
