I bought my GS7 10 days ago, and all sailed perfectly for eight days.

Since yesterday, I've been noticing that contacts are randomly erased from my phone. It has happened to three or four contacts at a time, on three separate occasions.

I use Outlook as the source, and sync contacts and calendar via Companion Link. I have never had this issue before. Not even on another small Android KitKat tablet that I have.

Twice I resolved the issue syncing via Companion Link, and the contacts showed up again. But on two occasions I've had to delete them from Outlook, re-enter, sync again.

Any suggestions?

My advice would be to use GMAIL to store your contacts. I don't see this being the phone I see it being your syncing method with 3rd party

I disagree.
Had all my contacts sync to google and yesterday they disappeared all of them .removed account and re synced google. still nothing
Even tmobile staff was baffled. in the end they swooped out the phone

See: Does google have a sync issue with contacts?

What I noticed is, if I add a contact from the call log or if someone messaged me in whatsapp and I add the contact from whatsapp, give it a few seconds and the contact disappears. What I am having to do to not have them disappear is to manually add them from the contacts app but this is very inconvenient

Still sounds like no definitive answer. Hmmm. I'll get back in a few days.

Sounds like user error. I've never had contacts disappear when using Gmail. If a major bug like that existed, it would be all over the Internet.

Make sure your contacts app is displaying the correct account(s). In all my years of experience with Android, every time I thought contacts were mysteriously disappearing or reappearing after deleted, it had to do with which accounts were being displayed. Go to Settings in your Contacts app and poke around and you'll probably find the problem. Also look to see if any of the contacts are linked.

I fixed my issue on my s3 simply by setting my hangouts app back to the factory program. Because my contacts didn't start dissappearing until my hangouts app was updated the last time

The source of the problem for me was saving as an outlook contact rather than a Gmail contact. I solved that by going to outlook app>settings>click email address>turn off sync contacts

This is a big problem, continuing to this day (late Aug. 2017), with the latest phones S8 plus.
Tech teams are baffled. It is enough to force me to give up oon the phone.

Sorry, but this is an android problem with new devices. I never had this with my iPhone, iPad, or other non android nor old android devices.

Something is wrong with the OS and device specific software. It is random contacts that disappear. a few at a time.

Please have an android expert look at this issue. I have it with my S7, S8, and now S8+. But never before.
