My Galaxy S8 has a malfunctioning front camera. I have the option to get a new phone, when I send my current one back.
Before I do the exchange, I want do a backup, and what's more important for me, safely wipe the content of the current phone.
How to do this? I have no root, just the plain Vodafone rom without any modifications.
When necessary I can connect the phone to a Linux or OSX machine, I don't own any Windows devices.
