Can I change proxy settings on my stock Android browser? I have a Samsung Galaxy S3, and I'm not experienced enough in Android to want to root it yet. 

However, I need a proxy server. Is there any way to change the proxy settings (for both WiFi and network, either through the phone or over adb)?

Thanks.
With terminal on your droid or via adb

The android web browser will read the proxy settings in its settings database. 

Spawn a shell:

&gt; adb shell


Init sqlite3 database manager to edit the settings database.

# sqlite3 /data/data/com.google.android.providers.settings/databases/settings.db


Run the query bruh.

sqlite&gt; INSERT INTO system VALUES(99,’http_proxy', 'proxy:port');


Close the session.

sqlite&gt;.exit


Profit.
