It isnt an error or anything man. Its how android phones are going to be from now on. The internal sd is for apps and the external (the one you add) one is for music, vids, that kinda thing.
There are root ways around it though if like youre a gamer and need a lot of app storage :thumbup:

 

if your that concerned look into link2sd app wont move the apps but symlink them for rooted devices only.

 

I wouldn't even consider putting apps on my external sd card. At least not until I went over 10 gigs of apps. This is my first phone where I don't NEED to put them on the sd card due to insufficient internal memory.

 

Yes. With 16GB of internal storage there is no benefit in moving to the external SD. You will diminish performance speed of running those apps. Moving an app to the SD card should be a last resort effort when running out of internal storage.. which should not be an issue with this phone

 

I was able to move it, I have the sh file for it but you need itid support
