Transfer data from Huawei Smartphone to Samsung Smartphone?

I would like to transfer all data (apps, contacts, whatsapp messages, login data etc.) from my Huawei mobile phone to my Samsung mobile phone.

The apps should be installed and not just copied.

With which free software is this possible?

PhoneClone from Huawei

First of all, the settings have to be like this in the Huawai smartphone:

Then sign in to the Samsung smartphone using the Google Account. The Google Account stores all the data. After logging in, all the data and apps are set up on the Samsung. You do not need any software for that.

Where do I find these settings and do I have to do a recovery afterwards?

But all data should be transferred, not just the contacts.
