Why does my Nothing Phone (3a) keep flashing “Log Tool keeps stopping” after the OS 4.0 update?
Critical Bug Report: Nothing Phone (3a) OS 4.0 Deployment
The recent deployment of Nothing OS 4.0 to the Phone (3a) has introduced a significant system instability. While users anticipated performance enhancements, many now face a disruptive functional error. A persistent system dialogue box flashes intermittently on the screen, severely hindering standard device usage. This issue compromises the user experience by interrupting active applications regardless of the task at hand.
The Symptom: Rapid System Interruptions
Affected units display a pop-up error stating “Log Tool keeps stopping.” This message appears and vanishes with extreme speed, often lasting less than a second. The duration is so brief that many users required screen recording software to capture and read the text. The error loops continuously. It creates a strobe-like interference that persists across the interface, affecting both third-party apps and system navigation.
The Diagnosis: Broken Diagnostics
The severity of this bug lies in its specific target: the error reporting tool itself. The “Log Tool” is the system component responsible for tracking faults and sending feedback to developers. Because this specific package is crashing, users cannot utilize the standard feedback mechanism to report the issue. Attempts to open the feedback tool result in immediate closure or a forced return to the previous menu. Consequently, the device cannot communicate its own failure to the manufacturer.
Scope of Impact
Primary reports stem from the Nothing OS 4.0 rollout. However, evidence suggests the instability is not exclusive to this version. User reports indicate similar behavior on Nothing OS 3.2, implying a latent issue within the logkit package rather than the core OS update alone.
Technical Workaround via ADB
For users unable to wait for an official patch, a temporary resolution exists. This method involves disabling the malfunctioning package via the Android Debug Bridge (ADB). This procedure requires a connection to a PC and familiarity with command-line interfaces.
Procedure:
- Connect the Phone (3a) to a computer with ADB installed.
- Enable USB debugging on the mobile device.
- Execute the following command in the terminal:
adb shell pm disable-user --user 0 com.nothing.logkit
Advisory Note
This command forcibly stops the process responsible for the crash. While effective, it disables the phone’s ability to generate system logs. Users should reverse this change once Nothing releases a stable hotfix to ensure future errors are properly tracked.
