acer cell phone model z220

Hi,

On an incoming call:

If the screen is locked

The number will be shown on the screen. Tap and drag the phone symbol in the middle of the screen to the right (green phone symbol) to answer the call or to the left (red phone symbol) to decline the call. To decline the call with a message tap and slide your finger up and choose the message.

If the screen is not locked

The incoming call will be minimized and shown at the top. Tap Dismiss to decline the call or tap Answer to accept the call.

Here is a link to the User Guide for the phone.

Hopefully this is of some help.
