Samsung Galaxy S5: How to Change Font Size in Messaging App in Android 4.4.2 Kitkat

By default, the Messaging app displays all conversations and messages using the font with medium size. In case you have accidentally changed the font size or if you feel that the font size makes you hard for reading, then you can easily adjust the font size according to your need so that you'll be easier to read the messages.


How to adjust the font size in Messaging app?
There are two methods available that can be used to increase or decrease the font size in the Messaging app, either by using the Volume key or the font size option.

Method #1: Using the Volume key
This method lets you adjust the font size in Messaging app easily by using the Volume up or Volume down keys. But you have to remember that this method won't work while you're playing music with the Music player app. See the following steps to enable and use the Volume key to adjust the font size:

1. Open Messaging app.
2. Tap or long press the Recent apps key to open up the additional options and then select Settings.
3. Tap Display.
4. Check the box in the right side of the Change font size to enable this option and let you adjust the font size using the Volume key.
5. Now, while you're composing a new message or viewing conversations or opening a conversation to read/reply/forward a message, you can use the Volume up key to increase the font size or the Volume down key to decrease the font size.

Method #2: Using the font size option
This option is available when you're composing a new message, viewing conversations or opening a conversation to read/reply/forwarding a text message. As the example, we'll try to adjust the font size using the font size option while reading a text message:

1. Open Messaging app.
2. Tap a conversation.
3. Tap or long press the Recent apps key to open up the additional options, scroll down the screen and then select Font size.

5. The selected font size will be applied to all of the messages.

As a note, when you have adjusted the font size either by using the Volume key or the font size option, it won't change until you re-adjust the font size or reset the Messaging app settings or clear the data.
