📱 Non-Root Users: LSPatch Setup Guide

If your device is not rooted (or you prefer not to touch root hooks), you can use the LSPatch variant (Simple_Flag_Secure_LSPatch_v10.1.apk) to patch any restricted app directly on your phone:

Note

Using LSPosed instead? This exact same APK is a fully compliant standard Xposed module! If you have root with LSPosed, you can simply install Simple_Flag_Secure_LSPatch_v10.1.apk, enable it in the LSPosed Manager, check your target apps in its scope, and you are good to go!

Recommended Tool

• JingMatrix LSPatch (Recommended modern LSPatch fork for Android 10-15+)

Step-by-Step Instructions:

1. Download & Install:
   • Install the latest JingMatrix LSPatch release APK on your device.
   • Download Simple_Flag_Secure_LSPatch_v10.1.apk from Releases.
2. Open LSPatch:
   • Open LSPatch and grant the requested storage permissions.
   • Go to the Manage tab → Tap the + button → Select New Patch.
3. Select Target App:
   • Choose the application where screenshots are blocked (either from installed apps or by picking an APK file directly).
4. Embed Simple Flag Secure:
   • Choose Portable Mode (embeds module directly so LSPatch app isn't needed later).
   • Under Embed modules, tap + and choose the downloaded Simple_Flag_Secure_LSPatch_v10.1.apk.
5. Start Patching:
   • Tap Start Patching. LSPatch will recompile and resign the target APK.
6. Install the Patched App:
   • Uninstall the original target app from your device (backup your data first!).
   • Install the patched APK produced by LSPatch.
7. Done! Screenshots and screen recordings are now permanently unlocked inside that app without requiring root access.

⚡ Rooted Users: Zygisk Edition Setup

Recommended Zygisk Providers:

• Zygisk Next (Recommended for Magisk, KernelSU, and APatch)
• ReZygisk CLI (Pre-release) (High performance alternative)
• Built-in Zygisk in Magisk

Setup & Troubleshooting for Zygisk Edition:

• Recommended Setup: Use the latest Zygisk Next or ReZygisk CI. They hook into apps properly even when modules or Zygisk are hidden or unmounted for that app!
• If Screenshots Aren't Unlocking (Standard Magisk Zygisk):
  • Magisk's built-in Zygisk completely unloads modules for any app checked in the DenyList.
  • To allow screenshots in a target app, turn OFF DenyList (Magisk), Umount (KernelSU), or Exclude Modifications (APatch) for that app so the in-app hook can load.
• If Detected by Banking Apps:
  • Simply add those sensitive apps to DenyList (Magisk), Umount (KernelSU), or Exclude Modifications (APatch) to hide root and Zygisk traces from them completely.

🛡️ Rooted Users: Standalone Edition Setup

The Standalone Edition patches screenshot restrictions directly at boot without needing Zygisk, LSPosed, or any meta-modules (like NoMount or Hybrid Mount).

It operates completely standalone and hides itself well on most systems. However, on some stock ROMs with strict kernel protections (such as Samsung Knox / One UI), the kernel does not allow mounting from in-memory staging, forcing the module to fall back to legacy direct bind-mounting to ensure it still functions. On these devices, the fallback mount path may be detected unless:

• You have a kernel with SusFS support, or
• You use a meta-module like NoMount to hide the mount detection.

Tip

If you are on Samsung Knox or a strict ROM and do not have SusFS or NoMount, simply use the ⚡ Zygisk Edition with the latest Zygisk Next or ReZygisk, which runs 100% in RAM with zero filesystem mounts.

🎛️ Privacy Mode (Instant Toggle)

Need to temporarily block screenshots and screen recordings for extra privacy? Simple Flag Secure includes a built-in Privacy Mode that lets you toggle states on the fly without rebooting your phone:

• ✅ ALLOWED: Screenshots & recordings work everywhere.
• ❌ BLOCKED (Privacy Mode): Screenshots & recordings are blocked system-wide.

How to use:

1. Tap the Action button in your root manager (Magisk, KernelSU, or APatch).
2. Press Volume Up [Vol +] within 30 seconds to instantly switch modes.
3. (Bonus) Press Volume Down [Vol -] if you ever need to record a quick diagnostic log.

Tip

You can also toggle it from a terminal (Termux) anytime:

• Turn Privacy Mode ON (Blocked): su -c "/data/adb/modules/simple_flag_secure*/action.sh block"
• Turn Privacy Mode OFF (Allowed): su -c "/data/adb/modules/simple_flag_secure*/action.sh allow"
