# Why Enhanced mode is necessary?


Enhanced mode provides the following features:

  1. No longer relying on logcat to detect app process creation
    • Avoid the problem that the app will not be isolated for a short period of time due to the possible delay of the log
    • Avoid the problem that the log is disable (e.g., Huawei EMUI disable log on boot)
  2. Start on boot
    • Avoid the problem that custom systems block start on boot (including but not limited to MIUI)
  3. Block system remount
    • Avoid remount triggered by the behavior of custom systems making the isolation invalid (e.g., MIUI 11)
  4. Record file access behavior for apps
  5. Modify/fix some of the app’s behavior to ensure that the app is functioning properly

# Performance impact

"Enhanced mode" only has a performance impact that can be ignored.
