I recently had a problem with my Samsung S7 edge. It keeps on restarting and after removing cache, it still restarts after a few minutes. I found out that the most effective way to fix it is a factory reset. The problem is that, I am overseas and I could not receive any calls or text. Hence, I would not be able to verify my Whatsapp number.
Does anyone know whether Whatsapp requires verification after factory reset or does anyone know how to fix the problem?
