Proxidize Android: Create 5G/4G Mobile Proxy Farms on Android Phones

Proxidize Android Legacy is an Android application that enables anyone to make 4G or 5G mobile proxy farms using their Android phones without the need of anything else. Just download the app, hit connect, and your mobile proxy will be automatically generated.

Proxidize created Proxidize Android as a proof of concept for Proxidize MPM (Mobile Proxy Maker). The app accomplished its purpose, but was eventually taken down from the Google Play Store for reasons mentioned below.

Proxidize Android Legacy is the predecessor of the upcoming Proxidize Portable application which will be a drastic improvement on this app.

• Super quick load balancing managed by global servers.
• Add your own custom tunneling server for higher security and speeds.
• Experimental: Change OS fingerprint for improved opsec.
• Experimental: Split connection to WIFI backend to get better speeds.

How It Works and Architecture

Proxidize Android Legacy works by establishing a connection to a tunneling server via reverse proxies and then launching a local HTTP proxy server. This makes the proxy accessible from anywhere on the web, as the tunneling server handles the port forwarding and routing.

The application will select a random port between 10000 and 60000, use it connect to the client and then create a proxy server based on the random port along with a randomly generated username and password.

Proxidize Android Legacy vs Proxidize Mobile Proxy Maker

This app is not a replacement for Proxidize Mobile Proxy Maker, but a proof of concept. You can use this app at a small scale for personal projects, but once you need a commercial-grade solution, you'll need Proxidize MPM for the following reasons:

• Such apps will always be naturally unreliable due to underlying infrastructure being designed mainly for IoT devices and not proxies.
• Low speeds. Since both incoming and outgoing connections are passing through the same network interface, the speed you get will be a fifth of the mobile speed.
• Difficult to manage at scale. It takes a 10 minutes to set up a 20-modem kit from Proxidize, but setting up 20 phones will take a full day if not more.

How to Create a 5G or 4G Mobile Proxy on Android Phones: (Turn Your Phone Into a Mobile Proxy)

• Download Proxidize Android Legacy APK File
• Install the APK on your device
• Open the app and press "Connect".
• Copy the proxy and you can use it anywhere.

And now you have created your very own 5G/4G mobile proxy!

How to Use on Windows MacOS (Create 5G or 4G Mobile Proxies on WindowsMacOS)

• Download any Android emulator such as BlueStacks
• Download Proxidize Android Legacy APK file inside the emulator (Open this page from the emulator and download the APK)
• Install the APK on your device
• Open the app and press "Connect".
• Copy the proxy and you can use it anywhere.

Using the Proxy

Format:

IP:Port:Username:Password

Example:

1.1.1.1:1565:abc:xyz

Explained:

IP or Hostanme: 1.1.1.1
Port: 1565
Userrname: abc
Password: xyz

Rotation/Changing the IP (How to Change Mobile Proxy Android IP Address Using Airplane Mode)

Proxidize Android Legacy has built-in rotation. To set it up, you need to set the app as the default assistant in your settings.

Automatically Changing the IP Address:

Proxidize Android Legacy allows you to set a rotation/IP change interval. To use it, you need to:

• Press "AUTO CHANGE IP" button on the home page.
• Select the rotation interval you wish to use.
• Select a time in minutes. Anything less than 30 minutes will harm your phone.
• Press "SET" and your settings will be applied.

Changing the IP Manually:

To change the IP address manually, you simple need to press the change IP button.

Changing the IP via URL/API:

Proxidize Android Legacy generates an IP change link/URL/API that you can use anywhere to change the IP.

To change the IP using the rotation link, you need to:

• Copy the change IP URL under "IP Change Link/API" by pressing the "COPY" button.
• Use the link anywhere or send a GET request to it.

A success response is:

{"response":"success"}

Supported Android Versions & Devices

Proxidize Android Legacy supports all armeabi-v7a running Android 6.0 to Android 12

Supported Android API from API 23 to API 31.

Tested devices:

All Android 6.0+ phones
Samsung A Series
Samsung S Series
Samsung M Series
Samsung Note Series
Google Pixel

Deploying Your Own Server

Proxidize Android Legacy allows you to deploy your own tunneling server to avoid using shared/congested servers. To do that, you need to:

• Create a new server on any host. Make sure you're on a public network with all the ports publicly accessible.
• Edit configuration file to add your server information.
• Edit CUSTOM SERVER fields to add your new server.

Example:

• Server IP = 5.5.5.5

• Make sure the server is x86-64 or AMD64 running Ubuntu 20.04

• SSH into your server

ssh username@5.5.5.5

• Clone this repo

git clone https://github.com/proxidize/proxidize-android.git

• Enter the repo directory

cd ./proxidize-android

• Edit the server.ini file to add an authentication token

vi or nano ./server/server.ini

• Add the following info, replacing PORT and TOKEN with your own values. Keep the port value as 2000 unless you have a reason to change it.

[common]
bind_port = PORT
authentication_method=token
token = TOKEN

TOKEN is used to authenticate which clients are allowed to connect to this server. It can be any random set of characters such as 12345678.

• Start the server

setsid ./server/server -c ./server/server.ini &

setsid is used to keep the process alive after you close the terminal.

• Add the new server information to your application by going to menu > Change Server > Custom.

HOST = The new server public IP address. In this example it's 5.5.5.5.

Binding Port = The port your selected.

Token = The token you selected.

• Save the details, exit the app and open it again and hit connect. You will now connect to your new tunneling server.

Using the App Without Connecting to the Tunneling Server First

In some cases, you might be able to connect directly to the phone without needing to connect to the tunneling server. The advantage of this is that you won't have to connect to the tunneling server first, which will offer 5-10% higher speeds.

• Make sure your carrier can give you a dedicated v4 IP. This is very rare and you will need to confirm with the carrier.
• Call your carrier and request they forward the ports for you.
• Get your public IP address by searching for what's my IP address.
• The app is listening on 0.0.0.0 so once you forward the proxy port, just connect to it using your public IP.
• You can also do that if you're connected to WiFi, but you'll need to forward the ports on your router.

Reporting Issues

Types of Issues That You Should Report:

• App keeps crashing on a specific device/Android version.
• Bypass battery optimization not working on a specific device/Android version.
• App stops working after a while on any
• Proxy Refusing Connection web error, even though the port and host are correct.
• If you see any of the following errors: 12020, 12033, or 12165.

How to Report the Issue:

• Full description of the issue including screenshots and any error codes
• Full device manufacturer & model name. E.g. Samsung SM-A105L
• Include a screenshot of the "Software information" page
• Full instructions to replicate the issue.

Any Issues Unrelated to the App Will Be Closed, Such As::

• I sent 1,000 threads to scrape Amazon and now the IP is banned.
• I'm using vanilla puppeteer or Chrome and I keep getting blocked or my proxy is detected.
• Any form of 407/authentication error. This means you're not using the right credentials. Refer to format section.
• 502 or 504 if you're using rotation. This happens when you're connecting in the middle of a rotation.
• Any situation where you're using your own server. (Unless you can replicate the issue when using the default servers as well.)

Updates:

This app is no longer maintained by Proxidize, but I (Abed) will be working on it in my free time.

Edit: I ended up finishing most of the planned features before schedule. So chances are I won't be making any updates to this app for a while.

Things I'll be adding:

• [x] Supporting Android 12
• [x] Add Android wake lock to keep the proxy alive.
• [x] Custom server from application.
• [x] Save ports between sessions.
• [x] In-app IP rotation button.
• [x] Automated IP rotation.
• [x] IP rotation API
• [x] Supporting more devices such as Asus, Alcatel, etc.
• [x] Auto-detect nearest tunneling server.
• [x] SOCKS proxies.
• [x] Prevent duplicate ports on server.
• [ ] Showing the public IP on the app interface.
• [ ] Change proxy format.

If you're updating to v2.0.0 from v1.0.0 make sure to delete v1.0.0 first.

FAQ:

Why is the app marked as harmful app/malware by Google?

A few months after publishing the app, Google marked it as harmful/PUP/malware app. I suspect it's because there's some Google watchdog that sniffed the traffic and found something harmful that was being transmitted by some of the users. Or it's possible that the behavior of the traffic being unencrypted and routed to a single server was similar to typical harmful app behavior that come across Google in the Play Store.

There are also a few AVs that have marked the tunneling client fast revers proxy, as a PUP, and it's possible Google Play Store did the same.

I've made some mitigations against this by changing the binaries to change the hash, but I suspect Google will still mark it as harmful by reading the strings, so you will need to disable Play Protect, otherwise, the app will likely get automatically deleted.

My proxy isn't working with Proxy Refusing Connection error?

Make sure you're using the correct port value, then exit the app and start it again. There's a very small chance you used an already used port.

My proxy stopped working after it used to work, can you help?

Exit the app and start it again. If it still doesn't work, make sure the app is still running on your device. Then please tweet @Proxidizehq and we'll take a look.

Why is my proxy slow?

The app uses reverse proxies created via websockets route to forwarding facing proxies. This technology is slow, unreliable and there's nothing I can do about it with the limited time that I have to work on this project. Apps based on this specific tunneling technology were created for simple IoT use cases, and not for pushing full bandwidth or proxies.

The Proxidize team is working on an entirely new app called Proxidize Portable, which will address all the short comings of this app using proprietary technology.

Another thing is such apps send both incoming and outgoing traffic from the same device, which means you will always get half the speed that you would normally get when testing the speed directly on your phone. If speed is important, you should use the full Proxidize MPM-OP: https://proxidize.com/

Where will this app work?

This app will work everywhere, unless:

• You are in countries that have ISP-level firewalls that block any proxied connections via DPI.
• You are behind a corporate firewall that blocks unknown ports.

I keep getting a 407 Error or the proxy keeps asking for authentication?

Make sure you're not mixing the small l with a capital I.

Proxidize Portable
