4. Choose how to Save Media
WhatsApp allows you to choose what type of media will be downloaded based on network type. This is a great trick to save your bandwidth if you are using a 3G or 4G internet package. Just head over to Settings->Data usage and edit the options according to your own needs. This is a pretty efficient WhatsApp hack to reduce your data usage.
3. Starred Messages
Sometimes while chatting on WhatsApp, someone types something that you want to save for later use or posts any useful information that you want to store, you can do that by putting a star on that text message bubble. Long press the bubble that you want to save and press the star icon on top bar.
