There are a couple of WhatsApp hacks you probably haven't tried since you started using the messaging app. However, these hacks will take just simple tricks or steps before you can unravel them. A lot of people don't know they can figure out the number one person they have interacted with the most on this messaging app.
Just like I said, you will need to follow a few steps before you can find this out. First, go to the WhatsApp settings, click on data usage, and then click on storage usage. After this, you will be able to see the ranking of your chats with other people and groups, plus the time and the total number of messages you have sent to such an individual or group.
Another thing you don't know is that you can create an event on your phone's calendar via WhatsApp. Most messages we send in the form of links, dates, and times are clickable. By clicking on the date, you will be able to add an event to your phone's calendar. Also, some don't know they can reply to a message by simply swiping a message to the right.
