   [11:14:27-settings] Android launch!
   [11:14:27-settings] ADB is running normally.
   [11:14:27-settings] Ming com. Android. settings. settings activity launch

   That is to say, the settings signature you write is inconsistent with the settings signature that comes with the system. You must first uninstall the original settings

2. Uninstall seetings

• If Adb uninstall com. Android. settings is uninstalled normally, failure is reported.

  The online search method is ADB shell "CD/system/APP; RM settings.apk ;"

  However, RM failed for settings.apk, read-only File System

• You must first execute this statement (in ADB mode, this is the root permission) ADB remount

  Prompt remount succeeded (remount is probably used to improve the read/write permission so that it can operate read-only files)

• Then you can run ADB shell "CD/system/APP; RM settings.apk ;"
• After the deletion is successful, run
  ADB uninstall com. Android. Settings
• Uninstalled successfully! Install your settings
