How to Change a WhatsApp Chat Background on Android Smartphones
Find the default WhatsApp chat background boring?
Want to change the wallpaper of all of your chat windows or just for one person?
Want to use one of your personal pictures as a background?
Then you are on the right page, because here...
...I will show you step by step how to do this on a Android smartphone.
Using a custom background (also called wallpaper) gives your chats a more personal look.
You can set a default background for all of your chats and also for each contact separately.
I've tested these steps on a Samsung Galaxy Grand Prime with Android version Lollipop 5.1.1, but this tutorial should work for all Android smartphones such as the Samsung Galaxy, Sony Xperia, Huawei, Lenovo, Motorola Moto, OnePlus X, Google Nexus, HTC, LG, and many other smartphones running Android 4.1 or higher (Jelly Bean (4.1 - 4.3.1), KitKat (4.4 - 4.4.4), Lollipop (5.0 - 5.1.1), Marshmallow (6.0 - 6.0.1)).
