Recently I have installed lineageOS 20 on my galaxy J7 2015. Everything works properly, but I have no access to my internal storage! File manager only shows the SD cards content and I can not access the internal storage via any apps. Even when I connect my phone to my laptop, the laptop lists only SD card. Also maybe I should mention that in other hand, TWRP only has access to my internal storage and shows the volume of my SD card 0. What could be the problem?
I did clean flash and wipe all of my data, but the problem exists! I went through this guide.
wiping data and formatting storage are different things
Yes, the problem has been solved! But the phone says
Format the SD card to use it! I have much data on the SD card.
