The summer Hands-on report says "persistent overheating" issues plague 5G hardware. By Ron Amadeo Thermal throttling is a fact of life for smartphones. SoCs generate a lot of heat, and when this heat can't be dissipated, processors react by slowing down and thereby generating less heat. Usually this is just an issue for heavy 3D gaming sessions or a phone directly exposed to sunlight for a long time, like when mounted on a car windshield. In the era of 5G, though, heat is also an issue for your modem. While the vast majority of people don't yet have access to a 5G phone or 5G service, PCMag's Sascha Segan has been flying around the country testing out the carriers' nascent implementation of 5G. So far, the heat generated by Qualcomm's first-generation chips is an issue. https://arstechnica.com/gadgets/2019/07/the-latest-barrier-to-5g-speeds-the-summer/ -- Bill Horne (Remove QRM from my email address to write to me directly) ------------------------------ Message-ID: <20190713021810.GA28353@telecom.csail.mit.edu> Date: Sat, 13 Jul 2019 02:18:10 +0000 From: Bill Horne <bill@horneQRM.net> Subject: Here's Why You Shouldn't Update Your Galaxy S10 Right Now By Alexander Maxham Samsung's latest update for the Galaxy S10, which includes the June 2019 security patch, has a pretty major flaw. It's locking users out of their phone. After updating their phone with the latest update from Samsung, users are reporting that they are unable to get back into their phones. The lockscreen simply won't let them in. One user said that they type in their PIN and then the screen goes black, then back to the lock screen. Which means that you really can't do anything with your phone right now. https://www.androidheadlines.com/2019/07/samsung-galaxy-s10-update-lock-out.html -- Bill Horne (Remove QRM from my email address to write to me directly) ------------------------------ Message-ID: <Pine.NEB.4.64.1907141915210.1547@panix5.panix.com> Date: 14 Jul 2019 19:17:00 -0400 From: Danny Burstein <dannyb@panix.com> Subject: EU "Galileo" GPS system remains down h/t Lauren.
