-     * Set a network-independent global http proxy.  This is not normally what you want
-     * for typical HTTP proxies - they are general network dependent.  However if you're
-     * doing something unusual like general internal filtering this may be useful.  On
-     * a private network where the proxy is not accessible, you may break HTTP using this.

-     * @param p A {@link ProxyInfo} object defining the new global
-     *        HTTP proxy.  A {@code null} value will clear the global HTTP proxy.
+     * This sets an HTTP proxy that applies to all networks and overrides any network-specific
+     * proxy. If set, HTTP libraries that are proxy-aware will use this global proxy when
+     * accessing any network, regardless of what the settings for that network are.
+     *
+     * Note that HTTP proxies are by nature typically network-dependent, and setting a global
+     * proxy is likely to break networking on multiple networks. This method is only meant
+     * for device policy clients looking to do general internal filtering or similar use cases.
