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.

-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.
