Sensor Tester: Changelog

Version 2.0.0

11th of November, 2026

Six new sensor types: the uncalibrated accelerometer, magnetometer and gyroscope, each with its estimated bias and listed right below its calibrated counterpart; the game and the geomagnetic rotation vector; and the true-north heading. The uncalibrated accelerometer needs Android 8.0 and the heading Android 13.
Units on every reading (m/s², µT, rad/s and so on), also in the maximum range and resolution on the details screen.
Steadier numbers on the main screen: each value is rounded to the resolution the sensor declares, so only the digits the sensor can actually tell apart keep changing. The details screen still shows full precision.
The details screen shows the accuracy reported by the sensor. “Power used” is now “Declared sensor current”, because it is a value the sensor declares, not a measurement.
The rotation vector shows its fourth component, cos(θ/2), and the heading accuracy in radians when the sensor reports them.
Proximity is shown in centimeters with a near or far label, decided by the same rule the phone uses to turn the screen off during calls.
Battery details add the current, average current, charge counter and energy counter where the device reports them, and tell AC, USB, wireless and dock charging apart. Missing or invalid battery values are shown as “unavailable” instead of as misleading numbers.
Every sensor shows its state: waiting for the first value, activation failed, or permission needed.
Readings always resume after the screen is locked and unlocked; before, they could stay frozen. The list also keeps its scroll position when you come back from details, Preferences or About.
Better accessibility: a hint on the main screen says to touch and hold a sensor for details, TalkBack, Switch Access and Voice Access offer a “View details” action, and the checkboxes in Preferences are larger and follow the system font size.
A refreshed look that stays close to the original: a dark Material theme, side margins, subtle dividers and a new launcher icon, with themed icon support on Android 13 and later. The About screen scrolls, shows the installed version and links to this website.
A consent form where the law requires one (the European Economic Area, the United Kingdom and Switzerland), and Privacy options in the menu to change the choice later. Usage statistics start only after the consent check. The banner ad adapts to the width of the screen.
After a while of regular use the application may ask, at most twice, through Google Play’s own rating sheet, for a review.
Android 7.0 or newer is now required, and the app is ready for Android 17. Devices with Android 6.0 keep version 1.2.10.
Other apps can no longer open the app’s inner screens directly. Updated libraries, including the Google Mobile Ads SDK and Firebase, and the build toolchain; the release build is optimized, so the download is much smaller.

Version 1.2.10 and earlier

2014 to 2025

The original application: live readings of the battery and eleven sensor types on one screen, a details screen for each, Preferences to choose what is shown, and Copy to Clipboard. Its updates kept it running on new Android versions.
