Google is rumoured to be launching a new Android TV dongle to be the Chromecast Ultra's successor. Codenamed Sabrina, it appeared at the FCC, which suggests the official launch could happen soon. The FCC filings show two new Google devices with model numbers GZRNL and G9N9N. The former is an "Interactive Media Streaming Device, while the latter is described as a "Wireless Device" on the FCC website. Based on the descriptions, GZRNL could be "Sabrina," while G9N9N could be its remote control. As expected, the filings don't share critical details about the device, except for Wi-Fi and Bluetooth connectivity.
The leak back in June revealed that the TV dongle will run on an Amlogic S905X2 processor, which uses four ARM Cortex-A53 cores and an ARM Mali-G31 MP2 GPU. It will supposedly support up to 4K videos, HDR10, HLG, and Dolby Vision standards. It is also expected to support Auto Low-Latency Mode and Stadia gaming. Google is set to launch the Pixel 4a 5G and Pixel 5 on September 30. So, there's a possibility we'll see Sabrina then.
