Direct answer

“Problems” checking and “verification” are useful on Android when you’re diagnosing whether a VPN connection is actually established and behaving as intended (for example, traffic routing, DNS handling, and app connectivity). They’re most helpful after setup changes, network switches, or repeated failures. The limit is that even successful verification cannot guarantee anonymity, safety, or access—because outcomes depend on device, network conditions, and external services.

What it means in practice

“Problems” means symptoms you can observe: the VPN app shows disconnected, websites don’t load, streaming services fail, certain apps behave differently, or DNS-related behavior looks inconsistent. “Verification” means checking for evidence that the VPN is functioning in the way you expect, using signals available on your device or from your environment. This is different from “trusting the provider,” because verification helps you detect misconfiguration and network-specific issues early.

How it works

On Android, a VPN app typically creates a protected tunnel and routes selected device traffic through that tunnel. When it works, you should see consistent app status (connected/active), and observable changes such as the external IP address shifting and DNS behavior aligning with your expectations. When it doesn’t, you’ll often see partial connectivity: the app may appear connected while certain traffic types, DNS queries, or apps bypass the tunnel.

To diagnose, first separate two layers:

  1. Connection layer: is the tunnel established?
  2. Routing layer: is traffic (including DNS) going through the tunnel as intended?

Limitations you should treat as real

A VPN does not guarantee anonymity, safety, or access. Performance and availability can vary by network type (Wi‑Fi vs. mobile), location, device model, provider-side capacity, and time. Also, “verification” can only measure what you can observe; it can’t prove every hidden aspect of data handling end-to-end.

If you see failures, remember that some websites and apps may block VPN traffic, and some networks may interfere with tunneling or DNS. Verification is therefore best used to troubleshoot your setup and narrow down causes, not to claim certainty about privacy or unrestricted access.
