I just realized yesterday that I experienced exatly the same issue as you. I lost all my locally safed contacts. Unfortunately I did not realize it, because most of my contacts have telegram and the telegram-contacts stayed in the list (of course only with the telegram-numbers. Email-adresses etc. were lost). I can not trace back the data-loss to a specific time. But I am pretty sure, that I did not loose them too long ago (probably with the last update a week ago) because I use the normal contacts regularily.
A few things I did in the last days that could have caused the problem were:
- updating to 17.09.3
- upgrading Xpricacy to PRO
-> to be able to install the s…-f…ing-whatsapp for my work without having my contacts stolen (I only needed one work-contact in my list which worked well with Xposed)
- installed uptodown and Yalp-store for test reasons (and to download the right-ignoring, identity-stealing, privacy-killing “whats-up with this-app?”)
[Side comment: Yes, I did not like being forced to using this app. And just installing it proved to me why in more than one way. I have never installed an app before demanding that many permissions. And perfidious messages like: “We make the installation even more easy for you: Just give us access to all your SMS messages.” Ahhh, yeah, for saving ONE CLICK to copy and paste a security-code I give you access to ALL MY PRIVATE MESSAGES!!! Seriously, what is wrong with these people???]
I did realize last week also that the name connected to SMS (which remained on the phone) were lost. But I did not have time to look into this yet. It is the same fault though, lost contacts.
First I tried to fix it by restoring my contact list from Titanium Backup, but with no success! I also tried to load the contacts directly from my SIM-card with no success! I can see the contacts on the SIM (when trying to import them from the card), but importing does not work. Of course I restarted my phone after the recovery attempts.
-> So I figure that for some reason my contacts are not lost, but they are simply blocked.
The android 6 permissions are all given. Xprivacy does not have permissions for “Contacts”.
From other posts, I red that AdblockPlus can cause this problem. I have the app AdAway which is similar. So I would like to uninstall it but red that people go into some safe-mode in TWRP before. Why is that? I was not in this mode before, but I guess you get there from TWRP.
Anyone any other suggestions for the issue? I have looked through quite a few older posts, but maybe I have missed one.
