I don't know what's happening to my phone. One fine day all contacts or names get deleted automatically from phone. I have ro see Whatsapp pictures to identify then. It happened 4 times in last 2 months. I have checked my ohone with avast antivirus too. What can be the problem. It's really very frustrating.
Thank you for reaching out, I can understand doing so experiencing these symptoms. When the symptom happens is there anything that is performed around that time? Do your contacts show the number but with no name or are the contacts emptying out showing no contacts? Are these contacts within the Contact app on the phone?
