Samsung's New Display Senses Fingerprints and More Across Whole Surface

-
Samsung has revealed "Sensor OLED", a new display panel technology that has many tiny light sensors embedded directly into the whole OLED panel surface. This allows the panel to read fingerprints anywhere on the display, as well as check cardiovascular health. Current in-display fingerprint readers utilize a seperate sensor module under a small part of the display; this new technology is embedded directly in the display itself and covers the whole display area. When placing two fingers on the display, (one from each hand,) the display "can measure the user's heart rate, blood pressure and stress level". Samsung also showed off several new foldable phone concepts using its flexible display technology. One is called Rollable Flex, a display that unrolls like a scroll to become five times larger, essentially transforming from a slim phone to a large tablet.

Apple Delays CSAM Photo-Scanning Feature

-

Apple will "take additional time to make improvements" before launching its technology to detect and report known child sexual abuse material (CSAM) in users's iCloud photos. The tools, first revealed a month ago, are designed to preserve user privacy by using sophisticated hashing algorithms that run on the user's device. Only once a threshold of at least 30 CSAM images is detected can photos be decrypted by Apple for manual inspection and potential reporting to authorities. Privacy experts have expressed concern over the feature, as some governments may be tempted to force Apple to search for other types of imagery. Privacy advocates also expressed concern that the system could be abused by third parties to implicate innocent people. Apple has responded to these concerns, stating that its database of known CSAM will never include images reported from just one country, and researchers will be able to verify that all Apple devices are using the same database of known ...

Google Optimizes Android so Apps Take Up Less Space

Google has released a new version of the Android Runtime (ART), a core component that turns app code into lower-level code that can run directly on that specific device. The update contains new optimizations that reduce the resulting code size by about 9.3%. This means most apps now take up less space in both storage and RAM. On the average Android phone, this means a savings of about 50–100 MB in storage. Thanks to Google's modular design of the Android architecture, the ART update does not require a full OS update. http://dlvr.it/Sz0yKl

AT&T Suffers Large Cellular Outage

AT&T suffered a large outage of its mobile network this morning. AT&T acknowledged the issue and said it is working "urgently" to restore service. The service DownDetector shows the outage starting around 4am this morning. DownDetector also shows corresponding outage reports for other national wireless carriers, but an order of magnitude smaller. Verizon and T-Mobile told the New York Times that their networks are operating normally, so the reports for other carriers are likely people trying to communicate with AT&T customers. http://dlvr.it/T36R5b
