By default, WhatsApp has a pretty weird and childish background for your chat messages. The good news is that you can change it. Here’s how.

默认情况下，WhatsApp的聊天消息背景非常古怪而幼稚。 好消息是您可以更改它。 这是如何做。

We’re using an iPhone in our example here, but the process is pretty much identical on Android.

在这里的示例中，我们使用的是iPhone，但是在Android上，该过程几乎相同。

Open WhatsApp, and then head to Settings > Chats > Chat Wallpaper.

打开WhatsApp，然后转到“设置”>“聊天”>“聊天壁纸”。

You have three options here. Wallpaper Library is a collection of WhatsApp’s built in backgrounds. Solid Colors are the simplest, single color backgrounds. And Photos (or Gallery on Android) are all the photos you have on your phone.

您在这里有三个选择。 Wallpaper Library是WhatsApp内置背景的集合。 纯色是最简单的单色背景。 照片(或Android上的图片库)是您手机上的所有照片。

Choose the category you want, and then tap the background you’d like to use.

选择所需的类别，然后点击您要使用的背景。

You’ll see a preview of the wallpaper you chose and, if you like it, just hit the “Set” button. It then becomes the background for all your chats.

您将看到所选墙纸的预览，如果愿意，只需单击“设置”按钮。 然后，它将成为您所有聊天的背景。

Nothing to it!

没事！
