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 ?
CM: The size of the LPDDR3 is 2GB and it features two DRAM die within the package in a stacked architecture. It is in a PoP orientation with the Octa processor. There is very little gap between the two packages as we had to decap both at the same time to salvage the die.
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.
That is correct. The original Google mantra of the "open" Android system has since essentially been closed by the US carriers as far as the consumer is concerned. The maintenance of the original galaxy S phones were discontinued years ago, yet I had the most recent Android jelly bean on my 3 year old phone simply because it was flashable and therefore self-serviceable. Now I've lost hot spot, flashability, and some other carrier crippled features as a consequence of "upgrading".
Comparing IOS with an Android phone with locked bootloader is like comparing Apples to Oranges. Even with a locked bootloader you have access to non-approved apps or can write your own. Try to do that with an Iphone that hasn't been jailbroken. Futher, the Android modding community is very strong. It shouldn't be long before there's an exploit to allow root and custom ROM's. My Droid Bionic also has a locked bootloader, but I was able to play arround with ICS and JB custom ROM's well before they released an official version.
"Even with a locked bootloader you have access to non-approved apps or can write your own."
can write your own app in iphone also..
"Futher, the Android modding community is very strong. It shouldn't be long before there's an exploit to allow root and custom ROM's." which is equivalent to doing jailbreak in iOS, afterwhich you can do most of the same stuff. And the iOS JBing community is pretty strong also.
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
