Common Issues with NetMirror
App Not Launching
Sometimes, the app just refuses to open. This might be due to a recent update or OS compatibility issue.
Black Screen During Mirroring
You hear audio but see nothing? That’s usually a rendering problem with your phone or TV screen settings.
Audio Not Syncing
The video plays just fine, but the audio feels like it’s from another timeline. Syncing issues are often network-related.
Lag or Delay in Mirroring
A noticeable delay can make games or real-time presentations unbearable. This is typically caused by network congestion or outdated hardware.
Device Compatibility Problems
Unsupported Devices
Not every phone or TV model works seamlessly with NetMirror. Make sure your devices are on the compatible list on the app’s site.
Outdated Operating Systems
Using Android 7 or iOS 10? It might be time for an upgrade. NetMirror performs best with newer OS versions.
Network-Related Issues
Wi-Fi Signal Weakness
If you’re connected to weak Wi-Fi, expect pixelated screens, lag, or failed connections.
Not on the Same Network
Both your phone and the receiving device must be on the same Wi-Fi network. It won’t work otherwise.
Firewall or Router Blocks
Some advanced routers or firewalls block casting protocols. Adjust settings like UPnP or open specific ports to fix it.
App Permissions and Settings
Missing Permissions
NetMirror requires access to your screen, storage, microphone, and network. If any of these are denied, it won’t work correctly.
Battery Optimization Conflicts
On some Android devices, battery-saving modes kill background services. Disable battery optimization for NetMirror.
Recent Updates Causing Bugs
New Version Glitches
It’s not uncommon for app updates to introduce bugs. Check user forums or reviews for confirmation.
Rolling Back to Stable Releases
Try uninstalling updates or reinstalling a previous stable version (APK method for Android).

How to Clear Cache
-
Android: Settings > Apps > NetMirror > Storage > Clear Cache & Clear Data
-
iOS: Reinstall the app (no direct cache clear option)
