I have a Galaxy S5 running KitKat 4.4.2 and the phone is rooted. I am new to the Android OS and need some help with permissions and getting my files to actually work from the SD card. I have a 128GB external SD card but once I move an app or movie from the internal storage to the SD card the phone says the file is no longer supported or the app just wont play.

On a side note, does anyone know where I can find a custom ROM to flash so that the OS underlines misspelled words w/ the red squiggly line?

Thanks in advance
(Phone is a Galaxy S5 Active on AT&T, Model: SAMSUNG-SM-G870A ver. G870AUCU1ANE4)

What MOD OS are you using? I have tried using Kies3 as well as taking the SD card out and moving them via PC. I believe I had a corrupt SD card
