How do I turn speaker phone


    • 1 Press the green "Phone" key on the main screen of your iPhone. This key has a silhouette of a traditional hand receiver and is located on the bottom part of the screen.
    • 2 Begin to use your speakerphone by making a call or accepting a call from other participants. You can make a call by going to your "Contacts" list or activating the keyboard and dialing a number. Incoming phone calls can be accepted by pressing the "Accept" key underneath the caller ID.
    • 3 Activate the "Speaker" function on your iPhone when you are ready to use your speakerphone. This button is located above the caller's information and allows you to switch on and off with one tap of your finger.
    • 4 Put participants on hold while you use your iPhone speakerphone. There is a "Hold" key at the bottom of the calling screen that lets you speak to people without bringing callers into the conversation.
    • 5 Access your contact information over the Internet while you use your speakerphone. You can reach the main page of your iPhone by pressing the "Home" button if you are on hold. The iPhone does not allow you to play music or use other audio options while on hold because you are still on the phone.
    • 6 Adjust the volume level before you begin a conference using your speakerphone. There are volume buttons on the side of the iPhone that provide detailed control over speaker sound levels.
    • 7 Mute the speakerphone if you must leave your office or take a break from a conversation. The "Mute" key is available on the call screen and instantly cuts off your microphone and the speaker.
    • 8 Add new contacts to your iPhone that you have called on your speakerphone. You can go back to your "Recent Calls" list or the keyboard to find numbers to add to your "Contacts" list.

I have a LG420G TracFone but the manual does not tell me how to use the speaker phone feature. Can anyone please help me?


I'm sure you've found this by now, but for the convenience of newer owners: When making a call, once you push "send" the speakerphone icon will appear at the bottom of the screen above the "OK" button. The icon also appears when you receive a call. Use the OK button to toggle the speaker on and off.

I can only hear when my speakerphone is on or my earpiece is plugged in


The speaker of your cellphone is broken.
You must visit the store you bought it from to fix it for you.
Probably it will need to be replaced by a new one.

Thank you
