Screen Magnifier

To zoom in, double-tap the screen with two fingers to change zoom levels. You can change view angles at any time while in zoom view by double tapping with two fingers and holding; then pan up or down on the screen to zoom in further up or out down.
Use WP8 Device as Hotspot
Go to Settings, System, and Internet Sharing. This full-screen interface provides a toggle for enabling and disabling the feature on the plus controls for setting up the SSDI (broadcast name) and network password. This allows you to use the phone as a mobile hotspot—one that can connect up to five devices: including PCs, tablets, iPods, or anything else that requires a Wi-Fi connection.
