How to test your camera and mic
before a video call
A job interview, a work call or an online class — it's the worst when you freeze up or nobody can hear you. DoCam checks your camera, microphone, sound and internet in about a minute and tells you in plain words what to fix, so the call goes smoothly. Free, right on your phone.
Why check ahead of time
A minute now beats “can you hear me?” later
DoCam turns on the camera and microphone, plays a sound and measures your internet — exactly what matters on a video call. And instead of just saying “works”, it tells you like a person would: whether there's enough light, whether the mic is picking up noise, whether your connection can handle HD video.
Advice, not “working / not working”
Instead of dry checkmarks, you get clear tips: “the camera needs more light”, “hold the phone a little closer”, “your connection can handle HD video”. You know exactly what to do.
What gets checked before a call
Everything a good call depends on
Here's what the express check looks at. Each one has its own status indicator, shown the same way in the app and in the tips.

Common call problems
And what DoCam tells you
Familiar situations — and how the check helps you catch them ahead of time:
- People can't hear you well — the mic is picking up echo or noise. The check shows the recording level and points to what's getting in the way.
- Video keeps freezing — your internet is too slow or unstable. You'll see whether it can handle HD video, or whether audio-only is the safer bet.
- Your face is dark or washed out — the camera needs more light, or the light is behind you. The check spots this and suggests moving.
- You can't hear the other person — it's the speaker or the volume. A quick sound check makes it clear.
Your data stays put
Nothing leaves the phone
The express check runs right on your phone: the camera, microphone and sound are handled on the spot — nothing is saved and nothing is sent anywhere. No sign-up either — just start and check.
