Here’s how;

From the Main Menu of your Vivo Y78+, head to Settings > Bluetooth > Connected Devices.

The further away the Vivo Y78+ devices are from each other, the less likely the connection will remain secure. As a rule of thumb, Bluetooth can work up to 100 meters, but to play it safe, always try and keep your devices under 50m apart.

2.9 Avoid interference of other Bluetooth sources

The final consideration you’ll want to think about is that Bluetooth radio waves, or wireless waves, can interfere with each other. This means they can bounce off each other or get muddled up and make things confusing from your devices.

With this in mind, you’ll want to make sure you’re limiting the amount of Bluetooth activity in the area where you’re trying to use a device. While uncommon, this could be the problem.

To fix this issue, turn off all the Bluetooth connections in the area. This includes computers, laptops, mobile phones, tablets, and any other Bluetooth devices you may have. Then, try connecting your Vivo Y78+ to the Vivo Y78+ device you were trying to use. If it works, you know you were experiencing Bluetooth interference.
