I have fairphone open 7 (sibon) without GApps
I had my contacts on my phone
When I activate an e-mail google acount in the e-mail aplication, I have lost most of my contacts !!! ( there are only the last ones that I added )
I have seen /data/data/android.providers.contacts/databases/contacts2.db but I do not understand its structure.
There are other similar closed topics but all without solution:
Is there any way to recover my contacts?
Google is the owner and master of all telephones including FP open without GApps?
