It's not so much a phone issue but how Android is changing along with makers.
There are tomes on the web about this change along with folk that rail against it.
I just checked my BLU HD 6.0 and the move to SD card is there on Android 4.4.2. It's going to update to Lollipop which may change this.
My old phone won't let me download apps to my sd card.I want a phone that will let me install apps on my sd card? Sick of trying to download apps and failing because the phone is full of pre installed junk i don't even use and i can't remove it.Whats the point of adding a card slot to a phone but they won't let you use it. The same goes for my tablet. Both are Samsung.
