The 1080p resolution is totally expected at this ... so it shouldn't be a surprise that the Pixel 4a's screen is flat. Still, it's worth a positive mention to encourage and reinforce the fact ...
The Samsung panel runs at a resolution of 1080 x 2400 pixels, with a 120Hz refresh rate, while the Pixel 4A screen has a 1080 x 2340 resolution but just a standard refresh rate of 60Hz.
Google's most affordable Pixel phone packs an all-screen design and high-end Snapdragon 730 processor in a compact body. Other features include 6 GB of RAM, 18W fast charging, NFC, and a headset jack.
Google Pixel 4a 5G is not officially announced yet ... 2 inches OLED capacitive touchscreen and 1080 x 2340 pixels resolution. The screen is protected with Corning Gorilla Glass 3.
With only tiny differences in case size from Pixel 7 models ... wide cameras and stereo speakers. The 4a has the least battery runtime and smallest screen (see below).
