I have rooted my device. I have installed crDroid-7.1.2-20171202-j5nlte-v3.8.3 and android 7.1.2

I am using j5nlte model of samsung. I have accidentally uninstalled contact and contact storage applications since my device was already rooted. After the uninstall process, I have installed simple contacts application from f-Droid When I am willing to create a new contact I could not create the contact and the system says

No app from this device

As I think, the problem was "contact storage application was uninstalled". I have downloaded below application to install the contact storage application. I could not installed and the error was

The package conflicts with an existing package by the same name

I can restore the device to get my system apps but I can't restore since I have some other issues.

Is there any way to get my system apps back. Do I have any method to save contacts without contact storage apk?

Afraid you need to re-install your ROM. Until you can do that, you can e.g. use OpenContacts from F-Droid. This is an addressbook/dialer that comes with its own contacts storage no other app has access to (privacy-focused), so it should work in your current situation.

  • Open contact app was installed but could not open. It always says "keep stopping"

    Sad to read that – but I don't know why that happens. Maybe ask the dev in the app's issue tracker? Ah, here's the issue, someone else experienced this as well. Maybe join in there, as the original reporter didn't respond anymore? The app is actively maintained and the author seems very "responsive".
