Say i plan to get a new phone somewhat soon, and i want to transfer all the saved progress i have on my current phone to the next one, are they any ways of doing that? With cloud storage servies like MEGA perhaps?

That is because you are on KitKat or above, when they completely screwed up external SD card permissions.
It's fixable, but it would require a lot of back and forth between Java and C, since you can't create or touch folders in C, and to touch files in C you have to open them in Java.
Yeah i have ...

I really want my files saved on the external SD card, but whenever i select any folder to be a user directory it displays the following: "Could not create directory". what can i do to fix this?
