No. All I did was export my contacts.vcf from my old phone (3T), copied that file to the new phone (7T pro) then imported contacts.vcf to the Contacts app. Worked fine. No issues since then.
Thanks for the feedback alleykat:
It is an odd one, seems anything I install from the Aurora store is doing the same thing, F-Driod apps are fine.
On further testing:
I added a dummy contact direct on the phone (not from my .vcf) and installed another app.
The dummy contact was the only one left following an app install.
Re-created the same issue running the same tests on my second McLaren 7T Pro? covers it off from being just the device it's self.
My initial thoughts are it is something in the store app not the ROM (MSe1969), if I get the time I will dig in and see if I can initiate or find some logging of the install process and feed back.
Not a major issue for me, this is the first time I have used the Aurora store, will take this as a warning and not use it going forward either
Thought I should bring it forward in case others see something similar
