StatusBack

Bring back the status-bar icons that Samsung One UI 7/8 hides on the home screen — VoLTE / Wi-Fi calling, Bluetooth, alarm, Do Not Disturb, hotspot, and more — each with its own toggle in a small settings app. A libxposed module (API 102), scoped to com.android.systemui only.

Changes apply instantly: no reboot, no SystemUI restart, no re-flash
Nothing is patched on disk; disable the module and everything reverts
Your own icon_blacklist (System UI Tuner / Settings.Secure) still wins

Requirements

Rooted device with Vector 2.2+ (or another API-102 libxposed framework) — Vector needs Zygisk (e.g. NeoZygisk with KernelSU)
Samsung One UI with the …statusbar.phone.ui.StatusBarIconControllerImpl layout — developed on a Galaxy S22 Ultra (One UI 8 / Android 16); other builds may rename classes, in which case the hook logs an error and does nothing

Install

Install this APK.
In Vector Manager, enable StatusBack with scope System UI (com.android.systemui).

Grant the one-time permission (root shell or adb):

adb shell pm grant io.github.fragtion.statusback android.permission.WRITE_SECURE_SETTINGS

Reboot once so SystemUI loads the module.
Open StatusBack and flip the toggles.

How it works

One UI's StatusBarIconControllerImpl.hideBySimplification(IconManager, String slot) returns true for the home and keyguard bars unless the slot is in config_status_bar_system_icon_allowlist. StatusBack hooks it and returns false for the slots you enabled — but only when the calling IconManager reports mLocation == HOME, so the keyguard and every other call path stay untouched.

The enabled slots are stored as a comma-separated list in Settings.Secure (statusback_restore_slots). SystemUI watches that key with a ContentObserver and calls refreshIconGroups() on change, which is why toggles take effect live.

Defaults before you save anything: ims_volte, ims_volte2, bluetooth, bluetooth_connected.

Slots

Slot	Shows
`ims_volte`, `ims_volte2`	VoLTE / Wi-Fi calling badge (SIM 1 / 2)
`bluetooth`, `bluetooth_connected`	Bluetooth on / device connected
`alarm_clock`	Alarm set
`mute`, `volume`	Silent / vibrate, sound-mode indicator
`zen`	Do Not Disturb / Modes
`rotate`	Rotation lock
`hotspot`, `bt_tethering`	Hotspot, Bluetooth tethering
`data_saver`	Data Saver
`location`	Location in use
`cast`, `screen_record`, `connected_display`	Cast / Smart View, screen recording, external display / DeX
`satellite`	Satellite connectivity
`camera`, `microphone`, `sensors_off`	Privacy indicators / sensors-off

wifi, mobile and mobile2 are already allowed by One UI and are not listed.

Limitations

A toggle only un-hides a slot SystemUI actually receives. If Samsung's IMS service doesn't publish ims_volte (or there's no second SIM for ims_volte2), there is nothing to show.
Some carriers render Wi-Fi calling as a variant of the Wi-Fi signal icon (USE_WIFI_CALLING_ICON); that path isn't touched by this hook.
Slot names come from SystemUI dumps on one device; volume in particular is unconfirmed.

Troubleshooting

List the slots your SystemUI currently has and their visibility:

adb shell
su
D=com.android.systemui/.SystemUIService
dumpsys activity service $D StatusBarIconControllerImpl > /data/local/tmp/s.txt
sed -n "s/.*slot='\([^']*)'.*visibleState=\([A-Z]*\).*/\1 \2/p" /data/local/tmp/s.txt

The module logs each distinct HOME slot it sees (HOME slot: <name> -> shown|hidden) through the framework log: check Vector Manager → Logs, or adb logcat | grep StatusBack.

If SystemUI misbehaves, disable the module in Vector and reboot.
