Hi dears,
Until today, by defining a Socks Proxy equal to “127.0.0.1:9150” in Telegram, I was easily able to use Telegram under Tor servers.
Today, after upgrading to Android version 13.5, the Telegram connection is no longer established!
What is the problem? Is this a bug in the new version?
best Regards
As far as I can see the 13.5 on Android uses a Unix domain socket (UDS) or IPC socket (inter-process communication) instead of a classic SOCKS proxy.
Using the “Orbot” app in “Power User Mode” should let you use a SOCKS proxy on port 9050.
Thanks for answering dear. But where is “Power User Mode” setting? I cannot found any options for it in my Tor Browser setting. I Should install Orbit separately? In previous versions, there was no need to install any separate apps.
You are welcome. Due to various reasons i do not use Tor on Android devices so i do not know how it was before 13.5.
To find out what is your problem here, i installed both apps and checked the configuration options & default settings. I do not find any options in 13.5 to set it to a classic SOCKS proxy, so i checked Orbot, which does have the “Power User Mode”. So yes, in my opinion you need to install Orbot to achieve your required configuration. Both apps are nowadays published by the same developer (at least in Google Play store): “The Tor Project”
But it seems Orbot is still mainly developed by the Guardian Project.
Maybe someone else has more experience on Android and has a different solution.
Do I need both Tor Browser for Android and Orbot, or only one?
While both Tor Browser for Android and Orbot are great, they serve different purposes. Tor Browser for Android is like the desktop Tor Browser, but on your mobile device. It is a one stop browser that uses the Tor network and tries to be as anonymous as possible. Orbot on the other hand is a proxy that will enable you to send the data from your other applications (E-Mail clients, instant messaging apps, etc.) through the Tor network; a version of Orbot is also inside of Tor Browser for Android, and is what enables it to connect to the Tor network. That version, however, does not enable you to send other apps outside of Tor Browser for Android through it. Depending on how you want to use the Tor network, either one or both of these could be a great option.

Thank you so much for your kindness and your really useful answer.
For your information, in the previous version, whenever I ran the Tor Browser, the Onion icon was appeared in the notification bar and then, all of the apps that had a proxy settings (such as Firefox browser, Telegram, etc) were worked well.
But in the new version, the Onion icon no longer appears! According to your advice, I installed the Orbot Apps separately, but unfortunately it does not work! Every time I run it, it gives an error message and closes immediately. 
May you specify the error message?
Just this simple message: “Unfortunately, Orbot has stopped”. This message appears three times and then, Orbot is closed.
