About this module

HyperOS Accessibility Fix is a systemless module that effectively prevents Xiaomi's HyperOS from randomly disabling your enabled accessibility services. It achieves this effortlessly by running a minimal background script, avoiding the need for heavy frameworks like Zygisk or Xposed.

Uninterrupted Accessibility

Maintain full control over your accessibility services without random system interventions, even under extreme battery-saving profiles.

Persistent Permissions

Automatically reverts unauthorized changes made by the system, ensuring your essential apps never lose their accessibility permissions.

Script-Based Efficiency

Instead of heavy frameworks, it utilizes a highly efficient logcat monitoring shell script. It's completely independent of Zygisk or Xposed.

LMKD Protection

The background service runs safely with a highly prioritized OOM (Out of Memory) score of -800, minimizing the chance of being killed by LMKD.

Under the Hood: Logcat Monitoring

On Android, when an accessibility application is force-stopped by the ActivityManager, its accessibility permission is immediately stripped. HyperOS is heavily hardcoded to trigger force-stops on specific events, such as toggling the Ultra Battery Saver mode.

This module operates by installing a background script that actively monitors the logcat event stream for these force-stop actions with virtually no system overhead. On system boot, it logs all enabled accessibility services to an a11y_watchlist.txt file. If HyperOS forcefully halts a watched service, the script instantly notices the mismatch and reverts the change made by system_server.

# How the monitor script operates in the background
detect_event ("Force stopping.*($PKG_PATTERN)")
if (service_in_a11y_watchlist):
verify_state ("Settings.Secure.ENABLED_ACCESSIBILITY_SERVICES")
revert_changes # Restore permissions instantly
# Prioritizing service to bypass memory limits
oom_score_adj = -800

Frequently Asked Questions

The developer specifically designed this module using shell scripts because Zygisk and Xposed frameworks tend to cause a range of compatibility issues and unexpected behaviors on their device. This pure scripting method yields incredible stability.

The primary script runs at a very high OOM score of -800 to prevent the Low Memory Killer Daemon (LMKD) from terminating it. Should it still be killed under extreme memory pressure, a secondary watcher script running at -900 will automatically restart it.

Yes. By utilizing this module, your selected accessibility services will continue running uninterrupted in the background even when you activate Ultra Battery Saver mode.
