I received a couple of the Qualcomm variants of this phone last week. Although I am impressed with the RFID and IR remote capabilities and other features (oh yeah, and the phone), my main issue is the locked bootloader that hinders flashing of standard Android on the device for those who don't care for the Samsung flavor. This is the main downside to me for getting a non-nexus Android phone regardless of features.
Allan : looks like you are the first with teardown of the S4. How about the size and speed of the new LPDDR 3 type of DRAM you found in it. How many dies for the DRAM ? How are they packaging all his ? PoP ? How much gap beteen the 2 packages stacked one over the other ?
