By changing my "wifi settings from public to private in Windows" it worked for me. But i wanted to know if this is secure? Is there a more secure way of doing this, because my lan has number of devices connected.

Follow the steps.

1.) Turn on USB Tethering & USB Debugging Mode in your mobile.
2.) Connect your mobile to your laptop through USB.
3.) Now just change the ip address (run "ipconfig" in cmd) from your backend code

For my part, I went to the "firewall" section of my antivirus and selected my Wi-Fi network as a private network, and it worked.

On my linux machine, it was a firewall problem. I resolved it by telling my firewall to allow connections from my phone's IP to the ports that expo exposes its dev server on (8081 in my case)

sudo ufw allow from 192.168.97.97 to any port 8081

Your phone's IP is in your phone's settings
