I just found out at work while on a Samsung technician training the galaxy as 4's are possibly going to be recalled. The frame of the phone is to weak and flex's easy resulting in the screen cracking down the middle. Samsung is determining how many they've sold and what the cost would be. Depending on the cost they'd either issue a recall or replace the phone when it breaks for that reason.
Just letting the community know.
