How to Configure a Proxy Server on Android – HowToGeek
Android allows you to configure proxy settings for each Wi-Fi network. This is sometimes required to access the Internet on a business or school network, for example. Your browser traffic will be sent through the proxy you configure.
RELATED: What’s the Difference Between a VPN and a Proxy?
The proxy you configure will be used by Chrome and other web browsers, but may not be used by other apps. Each app developer can choose whether it uses Android’s proxy or not. That’s another good reason why you should use a VPN instead of a proxy. WIth a VPN, you can force all app’s network traffic through the VPN connection. It’s a better way to hide your IP address or access geoblocked websites that aren’t available in your country.
This process is the same for all modern versions of Android, from Android 4. 0 through 7. 1. Some device manufacturers change the way Android’s Settings screen looks and functions, so you may find your Wi-Fi or proxy settings in a slightly different location.
Open Android’s Settings app and tap “Wi-Fi” to view a list of Wi-Fi networks.
Long-press the name of the Wi-Fi network you want to change the proxy settings for. Tap “Modify Network” when a menu appears.
If you haven’t already connected to the Wi-Fi network, you’ll need to connect to the Wi-Fi network and enter its passphrase before you can access the “Modify Network” options.
Expand the “Advanced options” section on this screen. Tap the “Proxy” option and select either “None” for no proxy, “Manual” to manually enter proxy server settings, or “Proxy Auto-Config” to automatically detect the appropriate settings for your network.
The “Proxy Auto-Config” option may not be available on older versions of Android.
If you select “Proxy Auto-Config”, Android will prompt you to enter the address of a proxy auto-configuration script, also known as a file. If your organization or proxy service provider needs a file, your network administrator or service provider will provide you with the address of the file you need to enter here.
Unlike other operating systems—Windows, macOS, iOS, and even Google’s own Chrome OS—Android does not support the Web Proxy Auto-discovery Protocol, or WPAD. This is sometimes used on business or school networks to automatically distribute proxy settings to devices on the network. If you enable “Proxy Auto-Config”, nothing will happen unless you also provide the address of a file where Android can acquire the proxy settings.
On a network that uses WPAD, you’ll have to either point Android at the appropriate automatic proxy configuration script or manually enter proxy server settings.
If you select “Manual”, you can manually enter the proxy server’s details. Enter the address of the proxy in the “Proxy hostname” box. Despite the name of the box, you can enter both hostnames like “” and IP addresses like “192. 168. 100” here. Provide whichever type of address you have. Enter the port the proxy requires in the “Proxy port” box.
If you want to have Android bypass the proxy for any addresses, enter them in the “Bypass proxy for” box, separated by commas. For example, if you wanted Android to access and directly without using the proxy, you’d enter the following text in the box:,
Tap “Save” to save your settings when you’re done.
Each Wi-FI network has its own proxy server settings. Even after you enable a proxy server for one Wi-Fi network, other Wi-Fi networks will continue to not use a proxy server by default. Repeat this process if you need to change the proxy server settings for another Wi-Fi network.

No one would answer what pacprocessor is? No one knows?
I was wondering what was myself. It seems to be elusive as I googled it and found nothing as well?

Here’s what methinks!!
Saw the source n I think it’s for proxy server rrect me if I’m wrong.

A proxy auto-config (PAC) file defines how web browsers and other user agents can automatically choose the appropriate proxy server (access method) for fetching a given URL.
PAC (Proxy auto-config) files contain a single javascript function,
FindProxyForURL(url, host). It gets called to determine what proxy should be
used for a specific request.
If that processor will be switched off probably there will be no chance to assign to each specific app its own specific custom proxy server for its own way of webaccess. So probably only the default way with using local web proxy server will be used with no exception for every app. Something like hosts file on Windows I suppose.

I thought, I was the only one who is facing this issue after removing Try to reflash your phone and debloat without removing and your phone should run properly. I see that is a very critical apps that doesn’t needed to be removed. As I observe after removing it, my phone starts to malfunction itself until my phone doesn’t start, only the boot animation.

I’m not sure about its definition but removing it causes my tablet not to work properly.

My theory, thus far yet to be dispoven after much trial-and-error experimentational research, is this: PacProcessor (i. e. /¿AKA? Proxy Processor) is basically an add(-)on-like type of application that is installed w/ any download of an android application that requires back-and-forth communication with a proxied website that is meant to be heavily trafficked by its users. PACProcessor (or Proxy Processor) is used for the purpose of lowering the amount of data needed on both sides of the proxy and for giving a certain degree of anonymity to the user (ie masking the users’ accounts info, locations, device info, identities for the purpose of preserving the privacy of each individual user). This allows the website, host, or server to recognize the user and to process any of the users requests and commands deemed permissible by the website, host or server itself, and also allows users to interact with other users anonymously with or without offering tools for users to interact on a more personal level with one another if the users involved permit it. These things are necessary for most, if not all; multiplayer or PVP gaming apps, dating site apps, and chatroom apps. I love google and all, but it doesnt know everything (not that i do, LOL. i’m further from it than most) I just googled Proxy Processor for the first time to find info about it to compare to my hypothesis, and this page is the first and only google result i have perused thus far. I saw the first post in this thread, and after reading the comment about google not being helpful, i laughed and sort of panicked at the same time and just had to contribute what i think I might know regarding the subject. Please keep in mind that this post states my theory on the subject. Please correctt me if anyone knows for sure that some if not all of this theory is incorrect. Thank you, Hank

I always thought ‘Pac’ in ‘PacProcessor’ was short for ‘Packet’… Which would make sense, seeing as how devices can only communicate by sending and recieving packets. Isnt that the bare bones?

Proxy auto-configuration (PAC) – Forcepoint
Standard (account-wide) PAC file URL (found on the Web > General page). This URL is an account-wide PAC file URL. This fetches a policy-specific PAC file on connections from recognized IP addresses, and the standard, global PAC file from unrecognized addresses.
Policy-specific PAC file URL (found on the General tab of a policy). This URL includes a policy identifier, which ensures that the PAC file specific to the policy is always retrieved. This can be useful to ensure that remote users always get the PAC file for a particular policy.
Note
If you have already deployed a standard cloud PAC file that uses a different URL than the one displayed on the page, there is no need to change it unless you wish to. PAC file URLs provided with earlier versions of your web product will continue to work.
Here, xxxxxx is a unique identifier for your policy.
Your Policy Specific PAC File Address is shown on your policy’s General tab. To access this screen, go to the Web > Policy Management > Policies page, then click the name of the policy.
Important
There is a security implication related to the use of PAC files. If someone could guess your unique policy identifier and download it, that person would know what sites were not protected by the cloud service and could, in theory, use them as an attack vector. To prevent this, PAC file identifiers are generated as non-sequential alphanumeric strings. Users cannot assume that the number on either side of their PAC file identifier is valid.
For additional security, use the HTTPS PAC file URL. Forcepoint also recommends disabling the Automatically detect settings option in your LAN automatic configuration settings.

How do I find my PAC address on Android?
PAC file addresses can be located on the Web > General page and on the General tab of a policy. In both locations, a default and alternate address is listed. Default PAC file address: the PAC file is retrieved over port 8082 by default, or 8087 for HTTPS.
