About this app

A tool app that lets you change or lock your phone's screen orientation with one tap from a notification.
Useful when auto-rotate is inconvenient, such as while watching videos, reading, playing games, or lying down.

Main Features
- Switch anytime from notifications: Change screen orientation with one tap from notification buttons.
- Per-app automatic control: Link specific apps with screen orientations and switch automatically for each app.
- Many rotation settings: Use portrait/landscape locks, sensor modes, reverse locks, and lying-down modes.

Supported Rotation Settings
Choose from 14 rotation settings.

[Basic Lock Modes]
- portrait: Lock to normal portrait.
- landscape: Lock to normal landscape.
- reverse portrait: Lock to upside-down portrait.
- reverse landscape: Lock to reverse landscape.

[Sensor-based / Auto Modes]
- full sensor: Rotate in all directions based on the sensor (system control).
- sensor portrait: Stay in portrait and flip based on the sensor.
- sensor landscape: Stay in landscape and flip based on the sensor.

[Lying Down / Special Modes]
- lie left: Rotate 90 degrees left relative to the sensor.
- lie right: Rotate 90 degrees right relative to the sensor.
- headstand: Rotate 180 degrees relative to the sensor.
- full: Rotate in all four directions based on the sensor (app control).
- forward: Rotate only in forward directions.
- reverse: Rotate only in reverse directions.
- unspecified: Use the current app's original orientation.

Required Permissions
Required: "Display over other apps"
Used to show a transparent control UI that requests screen orientation changes.

Optional: "App usage data"
Used only for per-app automatic control to detect the app currently open.

Troubleshooting
If reverse orientation locks do not work, try turning on "Auto-rotate" in device settings.

How It Works & Limitations
This app uses a transparent control overlay on top of other apps to request orientation changes from Android.
It also runs as a foreground service so control can continue after the app closes.
Because of this mechanism, the following limitations apply:

1. Persistent notification
Android requires a persistent notification while the app is active in the background. It cannot be hidden.
2. Battery and power saving settings
The OS may identify this app as a source of battery use and stop it. Excluding it from battery optimization may improve stability.
3. Security warnings or restrictions
Because this app uses the "Display over other apps" permission, some devices or security apps may show warnings or restrict it.
This permission is used only for screen orientation control. It is not used to read screen contents, perform input operations, or send data.
4. Conflicts with other overlay apps
Other overlay apps, such as blue light filters or screen capture tools, may conflict with this app.
5. Android 16+ large screen devices
On some Android 16+ large screen environments, such as tablets, foldables, or desktop displays, orientation settings may not be applied due to OS behavior.

Important Notes
This app can force orientations that the running app may not support. This may cause layout issues, temporary unresponsiveness, or crashes.
If this app causes issues in another app, that app's provider or developer is not responsible. Please refrain from contacting them about such issues.

Ratings and reviews

A life saver. I got a dead spot on my screen that blocks some very important buttons on apps, but using this lets me avoid the dead spot. Being able to stay in portrait mode while lying on my side is very nice too. My one suggestion would be that once the sensor settings are stable, I'd like to see the addition of one that allows other apps to set portrait or landscape, but ensures that the sensor can be used to flip it.

This app is perfect! It allows me to click a convenient button in the notification bar without relying on Gyro Sensor to rotate, and it can override other apps' defaults, so they dont rotate unexpectedly. The design is easy to read and no intrusive ads or designs, and runs in the background, with the notification bar, and many other things, being a setting. Another way to take some control of your android that Samsung doesnt give you!

Such a great app! Allows me to play one particular game - Evony - that's a PITA unless it's rotated when you're trying to find targets & objects on the map. The game itself won't rotate automatically without this app. Occasionally, I have to 'stop' & 'start' this app to get Evony rotating again, but it only takes a few seconds. Ads are only visible on the app's own window & not intrusive. I highly recommend this to anyone who wants to play Evony.
