Sam asked: “I use the WhatsApp app, and have problems with my contacts. It’ll take some contacts that starts with certain letters – like anything that starts with an “M” and it won’t show up on my contacts list and I’m trying to get that solved. “
Sam, as long as WhatsApp has permission to see your contacts, it’s supposed to give you access to them on its own.
Other than reinstalling your app, the only thing we can really tell you to do is make sure that your contacts are being shared with WhatsApp. Depending on whether you’re on iPhone or Android, how you do it differs, but on both you can check by going to Settings, and checking the permissions under “WhatsApp.” On iPhones it’ll just be there at the bottom of the Settings app, on Android you will have to go to “Apps” first.
If the contacts are not shared, turn on sharing.
On iPhones, you don’t see contacts until you tap the plus sign to start a new call or chat, on Android you can see a list of contacts and you can force a refresh from the menu, so if you’re on Android give that manual refresh a try.
If all else fails, you can try to reinstall the app and see if that has any effect, but all you’re normally expected to do is share your contacts with WhatsApp and let it do the rest.
