No need for third party apps
My Android 6.0 allows me to browse the intern memory without the need for third party apps. I simply do this*:
- “Storage and USB”
- [let it load a bit…]
- [scroll all the way down]
* Words may not correspond to the standard English version ones, since I’m just freely translating them from Portuguese.
Note: At least in my phone,
/storage/emulated/0 does not correspond to SD card, but to intern memory. This method did not work for my external card, but I never tried it with another phone.
Hope this helps!
