I’m a new user of Android and literally the first app I bought was DavDroid, as having sync between Fastmail and my phone is paramount. So far everything is working perfectly except for one issue. I am not sure if this is a DavDroid issue or an Android / Contacts app issue.
What is happening is that some contacts are being duplicated on the phone. The duplicate contact only ever contains a phone number, not any other information like email addresses. These contacts are not synced back to the Fastmail server. After deleting the duplicate contact, it seems to return after a few days. I cannot ascertain a pattern behind which contacts are being duplicated; it seems random. It is nothing to do with calling the contact, as many duplicates are people I haven’t actually phoned in years.
Key information to note is that I don’t use gmail or Google contacts. Whilst I am signed in to two Google accounts, I have explicitly set Android to not sync or use contacts. I doubled-checked that the duplicate contacts are not appearing on either of the Google accounts on their server; they are not.
As far as I can tell, the contacts are only saved on the phone somewhere, not on any servers. I have gone through every account in Settings > Users & Accounts and checked that only one of them is set to sync contacts, Davdroid.
I have searched the internet, stack exchange, and these forums for this problem, but I haven’t been able to find other people with the same problem.
Other relevant information:
- The phone is a Xiaomi mi A1, running AndroidOne 8.0.0
- Davdois is version 22.214.171.124-gplay
I would be really, really grateful for help here. I love having a neat and organised addressbook, and duplicates spoil the fun completely.
