PilferShush Jammer vs Privacy Flip
Side-by-side comparison of two open source alternatives
PilferShush Jammer
Features a passive jammer technique that engages the microphone thereby blocking other apps from using it. But does NOT listen to or record any of the audio from the microphone. It uses 0% CPU and no noticeable battery use. However is not intended to be left on permanently due to the variety of triggers that can cause audio_focus_state changes (VOIP etc). Also features an active jammer that emits tones constrained to the NUHF range of 18 kHz to 24 kHz range. User determined carrier frequency and drift limits with rate for random tone emissions depending on the device capabilities. For instance 20000 Hz carrier, drift limit 1000 Hz and rate slow - will output random frequency between 19 kHz and 21 kHz approximately every second. Audible artifacts are present during the NUHF tones but this may be changed in a future release. Experimental white noise output may not be very effective at blocking and is a somewhat annoying sound. The device speaker output may not have enough amplitude to block unwanted NUHF signals - testing will determine. * Manual start * Notification post when running * Auto stop and restart when telephony interrupts * Currently relies on audio_focus_state changes for auto-switching * Active jammer
Privacy Flip
Privacy Flip automatically manages your device's privacy features based on screen lock/unlock state. When you lock your device, it can disable Wi-Fi, Bluetooth, mobile data, location services, NFC, and even camera/microphone sensors. When you unlock, it intelligently restores the features you want back on. Works with Root OR Shizuku - Choose your preferred privilege method! Features: • Manage your device privacy based on lock/unlock state • Dual privilege support: Root OR Shizuku (no root required!) • Automatic privilege detection (Sui > Root > Shizuku) • Configurable feature control (Wi-Fi, Bluetooth, Mobile Data, Location, NFC, Camera, Microphone, Airplane Mode, Battery Saver) • Customizable timing delays (0-60 seconds granular, 2 minutes, or 5 minutes) • Smart "only if unused/not connected" modes for WiFi, Bluetooth, Location • App exemption system (skip privacy for specific foreground apps) • Samsung NFC payment override detection with opt-in auto-retry • Optional Accessibility Service for side button instant-lock support • Advanced multi-tier Bluetooth connection detection • Background service for persistent monitoring • Quick Settings tile integration Privacy Features Controlled: • Wi-Fi - Disable/enable wireless connectivity • Bluetooth - Control Bluetooth radio • Mobile data - Manage cellular data connection • Location services - Control GPS and location tracking • NFC - Control NFC sensor • Camera - Disable/enable camera sensor privacy (Android 12+) • Microphone - Disable/enable microphone sensor privacy (Android 12+) • Airplane Mode - Enable on lock (opt-in, disables all radios at once) • Battery Saver - Enable on lock (opt-in, reduces background activity) Note: Camera and microphone ignore custom delays and trigger immediately (if not in use to avoid interrupting calls), due to Android limitations Requirements: • Android 7.0+ (API level 24) • Android 12+ (API level 31) for camera/microphone features Choose your privilege method: Option 1: Shizuku (No root required!) • Shizuku app installed and running • ADB privileges via USB or wireless debugging • Perfect for non-rooted devices Option 2: Root Access (Recommended for rooted devices) • Root access via Magisk, SuperSU, or similar • Best performance with UID 0 privileges Option 3: Dhizuku (Device Owner method) • Device set as Device Owner or Profile Owner • No root required, no ADB after setup • Persistent privileges across reboots • Perfect for enterprise/privacy-focused setups Option 4: Sui (Best of both worlds) • Rooted device with Magisk • Sui Magisk module installed • Best user experience - automatic startup, no prompts Privacy & Security: • Zero telemetry - No data sent to external servers • Local storage only - All settings stored on device • No network permissions - App cannot access internet • Open source - https://github.com/dorumrr/privacyFlip
