[gannesh102]

Hi dear friends. I am using Samsung J7 4g DuOS. In previous days my phone whatsapp notification working properly. But Last recent days its not working properly. When I am open the app, then only show the messages. What is the solution for this problem.

I moved this from the S7 forum to the WhatsApp forum (since you don't have an S7 in the first place).
