Support and troubleshooting
Start with the compatibility check. A large share of mirroring problems are not problems at all - they are two devices that were never able to talk to each other, and no amount of troubleshooting will change that.
How do I cancel my subscription?
Cancel a screen mirroring app subscription through Google Play, stop a free trial before it renews, and request a refund if you were charged unexpectedly.
Why does my TV not appear in the list of devices?
Diagnose why a smart TV does not show up when you scan for screen mirroring, starting with protocol compatibility rather than network settings.
Why does screen mirroring keep dropping out?
Fix screen mirroring that connects and then drops out after a few seconds or minutes, covering Wi-Fi interference, battery optimisation and thermal throttling.
Why is there no audio when I mirror to my TV?
Fix missing audio during screen mirroring, including DRM-protected streaming apps that deliberately mute or blank the mirrored output.
Why does my phone say it does not support screen mirroring?
What to do when Android says screen mirroring is unsupported: which phones genuinely lack a Miracast sender, what they can still cast to, and why no app can add it.
Why is my TV showing a black screen when I mirror?
Why streaming apps show a black screen when you mirror to a TV, how to tell DRM apart from a genuine fault, and what to use instead.
Why is my screen mirroring so laggy?
Reduce screen mirroring lag and stutter: which delay is unavoidable, how the 2.4GHz band and thermal throttling make it worse, and when to use a cable instead.
Still stuck?
Email [email protected] with your phone model, your TV model and what happens when you try to connect. Those three things resolve most cases in one reply. More on the contact page.
Fixed it, or ruled it out?
If your two devices simply cannot mirror to each other, an adapter or a Chromecast will. The checker tells you which case you are in.
