Custom ROM and kernel development just got easier for developers working on the Galaxy S4 Zoom and the Galaxy S4 LTE-A, as Samsung has released the kernel source for both devices. The Galaxy S4 Zoom already had sources available, but the new ones are for the LTE variant, while S4 LTE-A's sources have been released for the first time, for the international variant that hasn't even been launched yet.
The source code for the Zoom is 377MB in size, while the S4 LTE-A code is smaller at 362MB. Hit the links below to download the code for either device.
