Contacts disappearing and mixed up

Hello,

Today I wanted to phone my daughter and was surprised to find that her contact portrait was the portrait of one of my clients. The client himself was not to be found anymore among my contacts, and my son also disappeared from my favorites and also from my contacts list.

How to solve this problem?

Thank you very much

 

Since I posted my post, I removed the portrait of my client from my daughter's contact info. I manually added the info of my client and also of my son.

But now the portrait of my daughter, in my favorites is the portrait of my son. I removed the photo of my son from my daughter, but soon after his portrait appeared again on my daughter's contact info.

 

My phone is a Pixel 4a that I purchased a month and a half ago.

Yes, I rebooted my phone several times after this happened, but it did not solve the problem.

:I did not mention in my post that, when I clicked on my daughter's portrait in the Favorites list > Contact Info > Edit contact, I found in the list of phones that she supposedly has, her mobile phone number, landline phone number but also the phone number of my client (which portrait replaced her portrait) and also my son's phone number!

It happened all of a sudden, and not after an update. When I think of it, I should mention that it happened just after I downloaded, tried and then immediately uninstalled, one after the other, 3 different Dialers apps (Drupe, Simple Contacts and Truecaller) and also 2 different Calendars. Since all these apps have access to my contacts, maybe that's the reason?

After posting, I have manually set back all the contacts that had changed or disappeared, deleted from my daughter's info the phones that were not hers, and replaced all the portraits. Ten hours have passed, and all seems to be back to normal.

Thanks.

 

Nope, I did not. Actually, I notice now that Automatically sync app data is turned on.

Thanks

 

Yes, I restarted, but that did not solve the problem. I had to manually set back the 3 contacts that have messed up info. As I mentioned in another post, the mess happened right after I downloaded, tried and then immediately uninstalled, one after the other, 3 different Dialers apps (Drupe, Simple Contacts and Truecaller) and also 2 different Calendars. Maybe this caused the problem with my contact list.

Right now, all is back to normal, but I would like to understand why it happened.

 

Hi puppykickr,

When I tried to understand the cause of the mess in my contacts, I looked into what I have done during the last half day before, and my guess was like you say, that one or several of the apps I have installed during this half day was the culprit (and I did not install any apps for several weeks)

I just uninstalled them, I did not delete the app data first. Thank you very much for the useful info. I will proceed this way next time.
