IN my S6 Edge+ is old battery. I want change to other Samsung but I consider also Huawey or Oppo. Moving contacts to other Samsung ,I think, will not cause problems, but how to move all to other smartphone?

you can use things like sms backup, use google contacts to backup your contacts or you export your contacts to the sd card from with the contact's settings. and whatsapp i think is saved on the server, but i'm not sure really as i very rarely use it.

WhatsApp isn't saved on the server, but it does a nightly backup and can be set to do a scheduled backup to Drive if you want. If you copy the WhatsApp folders to your new phone you should just be able to restore them there, or there's a way of restoring from the Drive backup.

It may be that some phone transfer apps will handle this for you as well. I did all of this 3 years ago but can't remember which method I used.
