Scrambled contacts

I have a Z10 since they were released but in the last month my contacts have become scrambled. When receiving a call or text, it will display an incorrect contact. When using contacts to make a call or send a text, it can't be relied on because it will call someone completely different. I have tried taking out the battery. Any other suggestions?

Re: Scrambled contacts

Hi and Welcome to the Community!

Here is a KB that discusses that error:

  • KB34577 Caller ID shows incorrect contact information for incoming calls and calls placed from the call log go to a different phone number than intended

Hopefully it contains something useful! There also are multiple existing threads on this site that discuss that exact error...your review of those might prove useful, and a search of this site, using the error message, error code, or symptom, should reveal all applicable existing threads to you.


If you remain on an older OS, you may want to try updating to the newer versions that hopefully have this issue corrected.

Good luck and let us know!

Re: Scrambled contacts

I had a similar problem with my Q10 when I first set it up. Having multiple cloud sources of contacts plus Verizon's free cloud-based backup app was causing phantom linking of contacts. Complete mess. The only solution for me was to wipe the BlackBerry clean and start again, this time with only my iCloud contacts as a database. No Facebook, no LinkedIn, etc. And definitely NO online backup by Verizon.

Re: Scrambled contacts

Backing up and then wiping the BB worked for me. The reinstall was very easy using BB Link. I was a little worried that I would spend a half day on it but it was dead easy and didn't require much attention.
