I’m confused about something and wanted to ask here. While looking through my contacts, I noticed my ex’s number is missing. The first time it happened, I thought maybe I accidentally deleted it, so I added it again. But now it’s happened a second time after I readded it on purpose just to see if it would disappear again and it did. The chat history is still there in whatsapp, and I know he’s been using whatsapp the whole time. He was using a modded version of it, and he’s a programmer, so he’s very tech savvy. It’s only his contact that keeps disappearing, no one else’s.
Is it actually possible for someone to somehow delete their number from your phone remotely? Or affect it through WhatsApp? Or is this definitely something on my end? I’m just trying to understand if it's even possible for that to happen.
