求问伪装成“Google（或其他应用）已停止”错误的隐私防护应用

Hey Christine, this sounds exactly like the category of privacy apps that use a fake system/app crash screen as a decoy to block unauthorized access—here’s a breakdown of what you’re remembering:

• Core Functionality: These apps are designed to make protected apps look like they’ve crashed (with messages like "Google [Service] has stopped" or custom app error prompts) when anyone who doesn’t know the unlock trigger tries to open them. The crash is entirely intentional, not a real system failure.
• Unlock Triggers: The three-tap or long-press unlock method you recalled is super common for these tools. For most variants:
  • Three quick taps on any part of the fake crash screen will bypass the decoy and open the protected app.
  • Some apps let you set a long-press on a specific area (like the "OK" button on the crash prompt) as an alternative unlock method.
• Popular Examples:
  • Fake Crash App Lock: One of the most well-known options—you can customize the crash message to mimic any app failure, set three-tap or long-press unlock, and choose exactly which apps to protect.
  • Privacy Hider (Fake Crash Mode): This app also hides app icons alongside the crash decoy, with three-tap unlock being a default setting for the crash screen.

Most of these tools let you tweak the crash prompt text to make it even more convincing, so it’s easy to pass off as a real system glitch to anyone snooping around your device.
