Help
This page covers common questions, permissions, and troubleshooting tips for Lirum Device Info.
Table Of Contents
Getting Started
Lirum uses a tab bar:
- Home: an at-a-glance dashboard.
- Tools: live monitors, diagnostics, and reference tools.
- Info: device specifications grouped by categories.
- Settings: updates, purchases, and app preferences.
- About: documentation, review, contact, and share.
Info: Searching And Refreshing
- Pull down on the Info screen to reveal a search field.
- Use the refresh button (top-right) to request an immediate data refresh.
- Tap a category header to expand/collapse it.
- Tap an attribute row to open a detail sheet (formatted value, description, and copy/share actions).
Permissions
Some tools and Info categories require permissions. If permission is denied, Lirum may show placeholders or a prompt to open iOS Settings.
Common permissions include:
- Location: needed for GPS/location data.
- Bluetooth: needed for scanning/connecting, Metrics Server/Client, and some accessories.
- Microphone: needed for the Microphone tool.
- Camera: needed for the Camera tool.
- Motion & Fitness: may be required by some sensor features (device/OS dependent).
- NFC: needed for NFC Read/Write on supported iPhone models.
Troubleshooting
Values Show "Loading" Or Are Blank
- Some attributes are populated asynchronously. Leave the screen open for a moment.
- Some values are device dependent, OS dependent, or restricted by iOS.
A Tool Is Missing
Tool availability can vary by device and platform (iOS/iPadOS/visionOS/macOS Catalyst). For example:
- Some sensors are not available on every device.
- Some tools are excluded on visionOS.
- Some tools can be locked behind premium or beta access, depending on your build and entitlements.
Bluetooth Scanning Finds Nothing
- Confirm Bluetooth is enabled in iOS Control Center or Settings.
- Make sure Lirum has Bluetooth permission.
- Stay on the Bluetooth screen for a few seconds and try starting a scan again.
Location Is Not Updating
- Confirm Location Services are enabled.
- Confirm Lirum has Location permission (typically "While Using").
- Try the refresh button in Info, or reopen the tool.
