In his tweet, he took two shots with the Pixel 4a, and two with the Redmi Note 7, to compare them. Truth be said, that's not the best comparison, but it sure does make look Pixel 4a camera samples look great.
The Google Pixel 4a camera samples look great
It's not difficult to notice that the picture Pixel 4a took of the Loudred figurine is superior. It offers much better colors, and far less noise than the one taken by the Redmi Note 7. It's also noticeably sharper.
Now, in terms of the picture that was taken outdoors, the color difference is also visible. The image taken with the Pixel 4a has much more saturated colors, the Redmi Note 7 picture looks washed out in comparison. It also offers a noticeably warmer tone, and it's sharper.
It's worth noting that the Pixel 4a will probably include a 12.2-megapixel camera on the back. The Redmi Note 7, in comparison, has a 48-megapixel sensor. The megapixel count doesn't have to mean anything, though, obviously.
It's not exactly a secret that Google's camera software is great, and does most of the heavy lifting. The Pixel 2 and 3 series cameras were excellent, and the same goes for the Pixel 4 and Pixel 4 XL cameras.
Well, the Pixel 4a will likely sport the main camera from the back of the Pixel 4. That means we're looking at a 12.2-megapixel camera with 1.4um pixel size, and an f/1.7 aperture. It will support both OIS and EIS, by the way.
The phone will be fueled by the Snapdragon 730, and include 6GB of RAM
The device will be fueled by the Snapdragon 730, if rumors are to be believed. It will include a 5.81-inch fullHD+ display, and that display will be flat, and will include a camera hole.
The phone will include a single camera on the back, and a capacitive fingerprint scanner. It will be made out of polycarbonate (plastic), most probably.
The Google Pixel 4a is expected to arrive in the near future. It was supposed to get announced during Google I/O, but the (physical) show got canceled. That probably means that the phone will be announced via a press release, or something of the sort.
The phone is rumored to ship to consumers on May 22 in Germany. That probably means that it will ship sooner in the US. That doesn't leave Google much time to announce this phone, so it will happen soon.
The Google Pixel 4a will probably arrive in 64GB and 128GB storage variants, both of which will include 6GB of RAM. The starting price point for the phone will be $399 in the US, probably.
