Google today expanded its Pixel lineup with two mid-range models: the Pixel 3a and Pixel 3a XL. The new models look much like the higher-end Pixel 3 models and have many of the same features, but use software to bring enhanced quality to more affordable hardware components such as the camera module. Cost savings also come from dropping water resistance, wireless charging, and the wide-angle selfie camera. The processor is Snapdragon 670 instead of 845, and the rear is made of plastic instead of glass. The Pixel 3a has a 5.6-inch display and sells for $399. The larger Pixel 3a XL has a 6-inch display and sells for $479. The phones are on sale starting today from Google. Tomorrow, Google is expanding distribution of its whole Pixel 3/3a lineup to T-Mobile, Sprint, and US Cellular, in addition to Verizon. The Pixel 3a phones include a 3.5mm audio jack, full-HD OLED displays, Night Sight and Portrait modes in the camera app, call screening, a squeeze shortcut for Google Assistant, USB-C, stereo speakers, Google's Titan M security chip, and a promise of OS updates for three years. The phones support fast charging and come with an 18-watt charger. The Pixel 3a is available in three colors: Just Black, Clearly White, and Purple-ish.
