Bluetooth and wifi interference

hi,

I am facing a strange problem. I have built an android app that reads data from my arduino via Bluetooth. Everything works fine and data from arduino gets transmitted to my app. However when my wifi is turned on and whenever I receive a message on whatsapp my app freezes and my Connection to arduino gets closed… Haven’t been able to figure out why this happens… I use serial communication to talk to the Bluetooth module…

WIFI and Bluetooth use the same frequency band , and will interfere with each other if both are used at the same time.
