Negative taliwas sa mga nababasa ko na effective daw ito..
Reason is orbot, proxydroid, autoproxy acts as gateway sa mga apps na blocked ng vpn app. It works as proxy listener and configured with the global proxy 127.0.0.1:8080 to work.
Si Psiphon ay ganun narin ang function kase naka tunnel sa whole device. So not much benefits from these apps unless yung vpn ay me blocked app sa device. Then puede mag configure ng proxy using the above mentioned app to tunnel yung blocked app. No help to avoid capping either.
