HUAWEI cell phone downloads do not work on SD card?

Have a HUAWEI phone and in the settings I have already saved the standard path to SD card
But if I want to load something like whatsapp… I'm told I should put spammer free.
how can that be?

This means only downloads like photos, music, etc. You can install apps without root only on the internal memory.

Which means without root

Yes without root means without root xD If you do not know what a root Google just is. And I do not recommend you to root because in most cases there goes out the warranty and you can even destroy the phone in case of a mistake.

Oh great
I just read what is root
that means I can't install another app
and on the SD cards can only photos and so on
