Unable to read internal storage/SD card on Samsung Grand Prime Plus so I follow a tutorial for setting my SD card as part of Internal storage with adb. Here is a photo of how it looks like:



As you can see, I have 7.88 gb used out of 37.47 gb and my device tells me I don't have enough space (the capacity of cellphone storage its 8gb), so I'm guessing there is something wrong with the configuration or something.

Can someone help me?

Cellphone: Samsung Grand Prime Plus
Model number: SM-G532M
Android version: 6.0.1

Thank you for your time.
remove the sd card 
remove apps 
reinstall the card as adopted stoRage 
then reinstall the apps while adopted storage is on
that will make the physical space of your phone stay empty and disable the notifications about low memory
