Android Security
Google has released the September 2019 Android Security Bulletin, giving carriers and device makers a fresh set of patches to install. Google device firmware images have also been released to the Google Developer site. Though Google puts out the Android security patches each month, the job of actually getting the fixes to end users falls on the telcos and/or device manufacturers themselves. Those partners vary in their ability to release the patches in a timely fashion.
I'm not a huge fan of concept phones. They tend to be very futuristic and extremely unrealistic. However, Designers Anish Shakthi, Phaniram Lalpet, Kamaljeet Kaur, Raghavendra Rao & Prateyush Das have produced a BlackBerry concept "phone" (Opus) that is not only simply beautiful but it's not beyond the realms of imagination that it could be produced.
