Some Android phones have the capability to connect to any Wi-Fi network automatically, regardless of connection quality or speed.

Mullvad VPN has discovered that Android leaks traffic every time the device connects to a WiFi network, even if the "Block connections without VPN," or "Always-on VPN," features is enabled.

The YouTube no network connection on Android device is usually caused by problems with the phone internet connection. It can also be caused by outdated software or corrupted app data.

When that happens, you might see the "your phone is not registered on a network" on your screen, which means your SIM card can't connect to your wireless provider's network.

Google has announced new cellular security features for its upcoming Android 14, expected later this month, that aim to protect business data and communications.
