CPU Info

CPU Info is an open-source device inspector. It puts processor, graphics, memory, storage, battery, sensor and Android build information in one interface, and includes a separate list of installed applications. It reads what Android, system files and hardware APIs make available; it is not a benchmark, malware scanner or guarantee that every vendor reports each field correctly.

This page covers F-Droid’s 6.7.0 build. We matched the 2.8 MB APK to F-Droid’s signed index and inspected the fixed release source. We did not compare its readings with laboratory instruments or test every manufacturer’s Android changes on a physical phone.

Hardware readings and their limits

The CPU screen lists the processor name, supported ABIs, core count and per-core current, minimum and maximum frequencies. Version 6.7.0 changed the ABI row to show every architecture the device reports rather than only the preferred one. Frequency values come from Linux cpufreq files; a kernel can hide them or return unavailable values, and a momentary clock rate is not the same as processor load.

Other screens report OpenGL renderer and extensions, RAM and storage totals, battery condition and electrical readings, display dimensions, cameras and Android sensors. Sensor availability and accuracy depend on the device. A missing temperature, frequency or camera characteristic can therefore mean that Android did not expose it, not that the hardware lacks it.

Version 6.7.0 expands the Android section with the security patch level, build number and fingerprint, base OS, build type, Treble support, seamless-update status, Google Play system update, media performance class, time zone and system uptime. It also counts user and system apps and can expand the feature flags declared by the system.

Installed apps and quick tile

CPU Info requests visibility of installed packages so its applications screen can list user and system apps, their versions and native libraries. From that list it can open an app, hand its details page to Android Settings or request its removal through Android’s normal uninstall interface. Those actions do not give CPU Info silent package-management access.

The app also includes a Quick Settings tile. While the tile is actively listening, it refreshes once per second and displays the average current frequency of the available CPU cores. Treat that number as a clock reading rather than a utilisation percentage or a thermal-throttling test.

The APK does not request INTERNET, and our static scan found no known tracker SDKs. It can display local identifiers such as Android ID or Google Services Framework ID when the operating system exposes them, but the inspected build has no permission to transmit them itself. Android backup is enabled by the manifest, so device backup behaviour remains subject to the operating system and the user’s backup settings.

About this file

• This is F-Droid’s source build of 6.7.0, signed with F-Droid’s key.
• It needs Android 7.0 or later and contains native libraries for 32- and 64-bit ARM and x86.
• It declares nine permissions, mainly for network/Wi-Fi state, installed-package visibility and opening Android’s uninstall flow; it does not declare internet access.
• Its measured SHA-256 is add5b106513c85c99689134959f1ed522bbd9ef54478d9e522b7d5658b33849d, matching F-Droid’s signed index.
• CPU Info is licensed under Apache-2.0. Our static scan found no known tracker SDKs.

CPU types in this build: arm64-v8a (64-bit ARM, almost every phone since 2017); armeabi-v7a (32-bit ARM, older and budget phones); x86 (32-bit Intel, emulators); x86_64 (64-bit Intel, emulators and Chromebooks).

Versions currently kept in the F-Droid repository. We host and check only the newest one. Full changelog.
