Phone Mirror

Mirror your phone screen to the car display and control the phone from the big screen. Video goes peer-to-peer locally — no server, lowest latency.

1Turn on your phone hotspot and connect the car to it
2Open the "CarSpace" app on the phone and tap "Start Mirroring"
3First time: allow the VPN permission and screen capture, then enable the "Touch back" accessibility service
4Come back to this page — it enters automatically; if not, tap the button below

Detecting the phone mirror service…

Enter Mirroring Now

Cannot open? Match the browser error below

Note: this page is served from the cloud. For security, browsers block automatic probes to private addresses, so "not detected" is normal and does NOT mean the phone is not ready. Just tap "Enter Mirroring Now" — the real error is the one the browser shows after navigation.

REFUSEDConnection refused: nothing is listening on port 8443 on the phone -> the app has not started mirroring, or its service failed to start (open the app and tap Diagnostics)
TIMED_OUTTimeout: packets never reach the phone -> the car is not connected to the phone hotspot, or that address range is blocked
NAME_NOT_RESOLVEDName not resolved: DNS lookup failed -> use another network, or point cast.evplay.cn to 100.99.9.9 manually
CERT_*Certificate error: the certificate inside the APK does not cover cast.evplay.cn -> rebuild the APK with the dual-domain certificate
BLOCKEDBlocked by browser: the private address is blocked -> switch the virtual IP to 7.7.7.7 in the app and rebuild the APK

Note: this page only works while the car is connected to the phone hotspot; other networks cannot reach the phone.
