The Nokia 225 4G and similar phones include a hidden app named 'NokiaBrowser' as well as the default Opera browser. This browser has less features, but is faster and doesn't insert ads between pages. You can open it as follows:
1. Open Opera via the 'Internet' icon.
2. Enter an image URL such as williamsmobile.co.uk/files/logo.jpg in the 'www.' field.
3. Click 'Open' below the image. NokiaBrowser will launch.
4. Press the left soft key to see the menu.
