Does this phone have to be rooted to move apps to the SD card? I have an app called Clean Master from Cheetah Mobile. It has a feature to move apps to the SD card but it's telling me that my internal storage and SD card storage is the same. Which doesn't make sense to me because when I go to settings / device storage you can see that my phone is recognizing the SD card and even shows the remaining storage on the card. I had this app on my previous phone and this feature worked but I purchased the phone used and it was already rooted.
