Hi all,
I've tried to find a solution, but none of the web-searches could "deliver" me a post, that scratched my problem.
That is:
If I open contacts and go to "Show all" (in german: "Alle anzeigen") I get an endless list of "WhatsApp-Call +49...." if the contact is a WhatsApp-Contact too.
The "bigger" problem comes, if I try to change some details of such a contact. At the moment I try to save it: it doesn't save, doesn't do anything until I stop the app.
I don't know if this is a "bug" in the sony-contact - app or in WhatsApp. Maybe someone knows the problem, maybe even a solution and would be so kind to post it here.
Just for the sake of completeness:
Model-No.: C6503
Android-Version: 5.0.2
Build-No.: 10.6.A.0.454
Thanks a lot in advance & kind regards,
Normand

Thanks a lot for all the helping replies 
I uninstalled WhatsApp, installed it again and: fixed...
99% of us are in the EU and have children to take to school or go out to work so an hour ago it was 8:15am - It was for me so we can't exactly stop doing what we need to do
it was not thought to be angry. Sorry therefor...
I was just wondering...
At least it was just to post the "solution" also...
For future reference boot on safe mode

if you don't experience the same issue while on safe mode then it's a third party app acting up.
