Android commonly captures traffic through VPNService or TUN capabilities, while iOS generally relies on App Store proxy tools that support subscriptions and rules. On Android, focus on background and battery policies. On iOS, verify App Store availability and subscription format. Do not run multiple VPN tools on either platform.
Verify the system, permissions, and compatibility separately
Android and iOS both display system VPN permission, but client sources, background restrictions, and subscription compatibility differ.
- Does the Android client support the current system version and background operation?(See Android downloads)
- Does the iOS tool support the subscription format, rules, and system version?(See iOS download guide)
- Did you grant system VPN permission?
- Does it conflict with another VPN or security app?
How to get started on Android and iOS
- On Android, first verify battery optimization and background-network permission
- On iOS, first verify app-store availability, payment status, and subscription format
- If a mobile connection fails, check system VPN status and app logs
- Do not enable multiple VPN tools at the same time
Mobile VPN permission is a system-level network-capture prompt
Most common tools on iOS are not official Clash clients
App-store listing status and prices can change
