A “unibody (likely plastic made) rear panel” is said to be in use, with the Pixel 3a and 4a both opting for plastic rather than glass.
The camera system is a notable improvement over the Pixel 4a by jumping to a dual-lens setup, but — again — it’s said to be the “same configuration as seen on the Pixel 4a 5G and Pixel 5” (12.2MP dual-pixel and 16 MP ultrawide).Other shared specs as an a-series phone include the 3.5mm headphone jack and rear Pixel Imprint fingerprint sensor.
Today’s leak offers no specifications or insight into what processor Google will use to power the Pixel 5a, though 6GB of RAM and 128GB of storage is a safe bet.
