The Pixel 3a briefly appeared in the Google Store yesterday. Specifically, the name "Pixel 3a" appeared in the drop-down Phone section of the Play Store, which had a new navigation design as well. The phrase "Google Pixel 3a Case" appeared as well with a URL that read "https://store.google.com/product/pixel_3a_case_fabric", giving us a hint at at least one accessory Google will have for its new phones.
Unfortunately, both links lead to dead pages, so there wasn't any new information about the Pixel 3a revealed. The Google Store has since been updated to remove the Pixel 3a references. The fact that they briefly appeared in the Google Store suggests that Google is getting close to launching the Pixel 3a and Pixel 3a XL, though, which would line up with the phones' rumored spring launch.
Also leaked by the Google Store last night is the Nest Hub Max, which we recently learned will be a smart display with a 10-inch screen, stereo speakers, and built-in Nest Cam. This unannounced device also appeared in the Google Store's drop-down navigation, along with an entry for "Google Home Hub/Google Nest Hub", which suggests that Google could rebrand its smart speaker as a Nest product.
We don't yet know when this mysterious Nest Hub Max might launch, but as with the Pixel 3a, the device's brief appearance on the Google Store could hint at a release that's close.
