Subject: The latest barrier to 5G speeds? 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.

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.

Subject: EU "Galileo" GPS system remains down
h/t Lauren. But a good catch
The time signals from US based GPS are used on
lots of telecom gear. I don't know if the Galileo
system has similar subscribers.

EU "Galileo" GPS system remains down
As I mentioned yesterday on Twitter, the EU's "Galileo" GPS system is
down. And it remains down, except for search and rescue transmissions
functionality:

aha, some more info:
"Another source close to the program told us, 'As far as I know, it is a
problem of the PTF [Precise Timing Facility] in Italy's time has an impact on
the whole constellation!"
