2. When all bootstrapped done go to check browser it will ask for normal browser or install Orweb .
3. Open Orweb and volla you r connected to tor but actually its not to tunnel your traffic to vpn go to Orweb settings.
4. Now note the proxy host and proxy port generally it is localhost(same as 127.0.0.1) and 8118 respectively but it may change so better to keep updated with port numbers.
5. Now go to wifi setting and long press the wifi (from which u r connected) and check advanced options.
6. Choose manual proxy option and put the host name 127.0.0.1 and port no. (e.g. 8118 ) which u noted in step 4
