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 ?
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".
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
