Shuffle / Random music ... is it ever going to be fixed????

I have experienced this issue as well, I have an iPhone 6 Plus and when I open the Sandisk app go to music then songs, I choose any song and click shuffle/random the same order of songs play every time. I can choose a different song later and it will work it’s way back to playing the same order of songs from before. I can even turn off the Sandisk media drive, turn in back on the next day and do the same process and it will play the same songs as the day prior in the same order. It is not an issue with iPhone, it is using the Sandisk app to play the music, I feel that something needs to be built into the software to have more shuffle options because it seems like it only has one option. This is a great device, but if the shuffle/random is fixed it would be the best.
