Q. A workaround for VPN follow these steps :

1. Go to psiphon and choose Browser-Only mode don't tunnel whole device.
2. Go to its logs tab and check the port of http proxy.
3. Now open WiFi setting and long press to your WiFi network (from which u are connected) go to modify tab and from check the advanced options.
4. Chosen manual proxy option and put host name as 127.0.0.1 and port as the no. which you noted in step 2 (eg. 8080) and click save .

Enjoy you have set up a VPN connection successfully.
You can open your browser and check your IP

Note: You have to undo this after you don't need VPN by changing manual proxy to none .

For those who want to use Orbot vpn

This is very similar to previous vpn workaround for psiphon
Just follow these step for Orbot
1. Open Orbot and long press to start orbot.
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

Now u can check https://check.torproject.org from any browser and volla Congo this browser is configured to use tor.
Sorry for long guide but it is detail enough so that anyone can easily setup tor in cm builds.

Note: You have to undo manual proxy option to none after you don't use vpn.
