Proxy on mobile

How do you effectively use a proxy on your Android phone? I downloaded Collage Proxy from the Playstore, but after connecting my browser still leaks. I tried blocking webrtc on Chrome without any success. Can someone recommend an app or browser that can help mask location? Biggest issue is webrtc leak.

You need to root your phone and download proxydroid

Thank you.

Use European proxy , with last v26 api update Proxyconfig.setproxy() and any Apple products useragent. Even elon musk can't detect your location I mean Twitter.
The native webkit doesn't support webrtc use it.
What else mmm canvas is edited through runtime , if you are lazy use adb to change the format of your screen.
Don't need to root the device just install your custom app in system folder .
Anything else can be done with code it depend on what you are planning to do with your proxy.

You can try SocksDroid App, it is proxy utility client for android devices
