Become unreachable for cellular calls while mobile data keeps working.
Ghost Mode makes your phone look switched off to anyone who calls — they hear "subscriber unavailable" — while LTE / 5G data keeps working. Messengers, maps and music continue as usual; only cellular calls stop reaching you. No airplane mode, no call-blocking rules.
- Works without root through Shizuku (or Sui and compatible forks); root via KernelSU, Magisk or APatch is detected automatically.
- Exact restore. Before turning on, the app records the original network types, the values of every setting it changes and the IMS services it disables. Turning off puts back exactly that — even if you switched preset or SIM in between, or rebooted.
- Presets for Pixel / stock Android, Samsung One UI, Xiaomi HyperOS, OnePlus, vivo / iQOO and Android 9–11, plus your own command sets with JSON import and export.
- Dual SIM: make SIM 1, SIM 2 or both unreachable.
- Quick Settings tile, home screen widget, launcher shortcuts.
- Schedule (e.g. every night 23:00–07:30) and an auto turn-off timer.
- Reboot-aware: re-applies itself after a restart when root / Sui is available, otherwise shows a notification.
- Diagnostics per SIM, a full command log and statistics.
- Material You design, dark and light themes, English and Russian.
- No ads, no trackers, no analytics. No network access unless you enable the optional update check.
| Minimum | Recommended | |
|---|---|---|
| Android | 8.0 (API 26) | 12+ (API 31+) — telephony shell commands used by most presets |
| Privileges | Shizuku v11+ or root | — |
| Network | LTE coverage | VoLTE-capable carrier |

- Get access — one of:
- Shizuku: download the APK from GitHub (the Download Shizuku button in the app opens the same page), start it via Wireless debugging (Android 11+) or ADB, then tap Grant access in Ghost Mode. The actively maintained fork thedjchi/Shizuku works too and can start itself after a reboot, so Ghost Mode can re-apply the mode without root.
- Root: open Ghost Mode and allow the root request in KernelSU / Magisk / APatch.
- Pick a preset on the Presets tab. Start with Universal; switch to your vendor's preset if calls still get through.
- Tap the ghost. Check from another phone: you should hear "subscriber unavailable", while mobile data keeps working (turn Wi-Fi off to be sure).
Not working? Open Settings → Diagnostics and Command log, then open an issue with the copied log.
Presets are lists of shell commands executed through Shizuku or su. The built-in ones combine:
| Lever | Command | Effect |
|---|---|---|
| IMS off | cmd phone ims disable -s <slot> |
No VoLTE / VoWiFi registration |
| LTE only | cmd phone set-allowed-network-types-for-users -s <slot> 01000001000000000000 |
No 2G/3G fallback (CSFB) for calls |
| IMS package | pm disable-user --user 0 <ims package> |
For firmware that ignores the IMS command |
| Settings | settings put global preferred_network_mode… 11, volte_vt_enabled 0 |
Samsung, Android 9–11 |
| Preset | For | What it adds |
|---|---|---|
| Universal | Any Android 12+ (default) | Disables the IMS service the phone actually uses (detected at runtime) |
| Stock Android / Pixel | Pixel, Motorola, Nothing, near-stock | IMS off + LTE only |
| Xiaomi HyperOS / MIUI | Xiaomi, Redmi, POCO | Same as stock |
| Samsung One UI | Galaxy S / A / Z | VoLTE switches, preferred_network_mode for all subscriptions, Samsung IMS packages |
| OnePlus / OxygenOS | OnePlus 8–13 | Qualcomm / MediaTek IMS packages |
| vivo / iQOO | OriginOS, Funtouch OS | Same as OnePlus |
| Android 9–11 | Phones without the Android 12 commands | preferred_network_mode + airplane-mode toggle |
When you create your own preset, these placeholders are available:
-s 0— rewritten to the selected SIM slot; the command runs once per slot.{{SAVED_MASK}}— the network-type mask captured before the mode was turned on.{{IMS_PACKAGES}}— the IMS service packages currently used by the selected SIMs.
Original values of settings put keys and packages disabled with pm disable-user are restored automatically.
Warning
Do not rely on Ghost Mode when you must be reachable for emergencies.
- SMS may be delayed until the mode is off on carriers that deliver SMS over IMS.
- Call forwarding "when unreachable" sends callers to voicemail instead.
- Some Samsung models drop VoLTE registration only after a reboot.
- Commands differ between firmware versions. If a preset does not work, send the diagnostics and command log.
- Use the app only on your own device and in line with local regulations.
Requirements: JDK 17+, Android SDK 35.
