How to merge a contact or client in your contacts list.
If you have two contacts that are actually the same person, the best practice is to merge them. Caution. Please understand what this entails
Go to the Main contact window.
In the Main contact window, either Search for a contact or scroll down. Tap the contact you want to merge (e.g., the one that is not the main one) to highlight it (the name turns orange, and the contact appears in the left window).
Tap the down dots and then tap "Merge contact".
This will open the "Merge contacts" window.
Search for and tap the person you want to be the main contact (i.e., the main contact for this person). You will see the "source person" and the "Target person". You can exit by selecting the back arrow or "exit" at the top right of the app. You can swap the source and target person by clicking the "swap arrows" to the right of the app. Tap "next". You will see a page showing what will be copied in the merge. It's important to read this carefully to make sure you are happy with the result. If you are happy with the merge, click "Finish". the two contacts have now been merged into one.
