Android 8.0's 'Streaming OS Updates' Will Work Even If Your Phone Is Full (arstechnica.com) 40

Regardless of whether or not your phone is full of pictures, or videos, or apps, you will still be able to download and install an OS update with Android 8.0. According to the latest source.android.com documentation, Google has cooked up a scheme to make sure that an "insufficient space" error will never stop an update again. Ars Technica reports: Where the heck can Google store the update if your phone is full, though? If you remember in Android 7.0, Google introduced a new feature called "Seamless Updates." This setup introduced a dual system partition scheme -- a "System A" and "System B" partition. The idea is that, when it comes time to install an update, you can normally use your phone on the online "System A" partition while an update is being applied to the offline "System B" partition in the background. Rather than the many minutes of downtime that would normally occur from an update, all that was needed to apply the update was a quick reboot. At that point, the device would just switch from partition A to the newly updated partition B. When you get that "out of space" error message during an update, you're only "out of space" on the user storage partition, which is just being used as a temporary download spot before the update is applied to the system partition. Starting with Android 8.0, the A/B system partition setup is being upgraded with a "streaming updates" feature. Update data will arrive from the Internet directly to the offline system partition, written block by block, in a ready-to-boot state. Instead of needing ~1GB of free space, Google will be bypassing user storage almost entirely, needing only ~100KB worth of free space for some metadata. Ars Technica goes on to note that the feature will be backported to Google Play Services, and will be enabled on "Android 7.0 and later" devices with a dual system partition setup.

Ask Slashdot: Are My Drone Apps Phoning Home? 132

Slashdot reader bitwraith noticed something suspicious after flying "a few cheap, ready-to-fly quadcopters" with their smartphone apps, including drones from Odyssey and Eachine. I often turn off my phone's Wi-Fi support before plugging it in to charge at night, only to discover it has mysteriously turned on in the morning. After checking the Wi-Fi Control History on my S7, it appears as though the various cookie-cutter apps for these drones wake up to phone home in the night after they are opened, while the phone is charging. I tried contacting the publisher of the Odyssey VR app, with no reply.

I would uninstall the app, but then how would I fly my drone? Why did Google grant permission to control Wi-Fi state implicitly to all apps, including these abusers? Are the apps phoning home to report my flight history?

The original submission asks about similar experiences from other drone-owning Slashdot users -- so leave your best answers in the comments. What's making this phone wake up in the night?

Are the drone apps phoning home?
