In a day some selected #contacts seem to go #missing.. it's very strange? Have checked #sync settings have #screened my phone for #virus (none) have tried different contacts apps still the details go missing
Go to contacts Click on three lines in left side Then click on top box And select all contacts If u like my comment accept it as solution by clicking three dots😊
My suggestion is always sync contacts to your Gmail account. It is the best. If anything goes wrong or even if you replace phone you can restore it from Gmail the moment you add your Gmail ID. All contacts will sync to your phone. Goodluck
