Google Pixel 3a and 3a XL Overview

Google announced the Pixel 3a and 3a XL, two new mid-range smartphones, on May 7, 2019. The product release date was May 15, 2019. These devices may have been inexpensive but offered a feature-full experience.

Pixel 3a:

The Pixel 3a’s 5.6-inch OLED screen has a pixel density of approximately 441 ppi. The screen takes up about 75% of the front, making a huge aesthetic statement. The brains of the Pixel 3a are an octa-core CPU running on a Qualcomm Snapdragon 670 (10 nm) chipset (2×2.0 GHz 360 Gold & 6×1.7 GHz Kryo 360 Silver).

With its 12.2 megapixel rear camera, OIS, and phase detection autofocus, the Pixel 3a can record 4K video at 30 FPS. The 8-megapixel front-facing camera makes taking selfies and participating in video calls easy.

The Pixel 3a’s non-removable Li-Po battery is 3000 mAh, which is a solid balance between power and battery life, and it also supports 18W wired charging via PD2.0.

Pixel 3a XL:

The Pixel 3a XL has a 6.0-inch OLED screen with a 1080 x 2160 resolution and an approximately 76.3% screen-to-body ratio, both of which enhance the viewing experience. Its Qualcomm Snapdragon 670 (10 nm) chipset and octa-core CPU (2×2.0 GHz 360 Gold & 6×1.7 GHz Kryo 360 Silver) are the same in both the Pixel 3a and the Pixel 3a XL.

The camera is excellent, packing the same wide-angle lens and 12.2 megapixels as Google’s Pixel 3a. The front-facing 8-megapixel camera takes gorgeous selfies and records video calls in superb clarity.

Faster wired 18W charging with PD2.0 and a larger 3700 mAh non-removable battery make the Pixel 3a XL ideal for extended use.

The Pixel 3a and 3a XL were attractive options for consumers who want a powerful smartphone but don’t want to break the bank to get it since they strike a solid balance between low pricing and high-end hardware.

The Pixel 3a series stood out due to its fantastic display, quick processor, significant cameras, and appropriate battery capacities, as well as its seamless hardware and software integration.

Charge Your Phone

It’s highly recommended to charge your handset before unlocking the bootloader to avoid your device from shutting down occasionally while going through the process. Keep at least 50% of the charge or higher for a smooth operation.

Download ADB and Fastboot Binaries

You can skip this adb and fastboot part if you have already installed TWRP Recovery on your Pixel 3a and 3a XL.

Using the ADB and Fastboot commands (platform-tools), you can boot your Android device into the bootloader mode (download mode), making it easy for you to proceed with further steps. ADB (Android Debug Bridge) creates a connection or bridge between the device and the computer to sideload files.

Fastboot is a more advanced command utility tool for Android devices that works with computers. You can download ADB and Fastboot Binaries (Platform-Tools).

Download Google USB Drivers

To create a strong and successful connection between a mobile device and a computer using a USB data cable, you will need a USB Driver. It is essentially a set of files that enables you to transfer files between the connected devices, flash files on the handset, and much more.

It is important to note that USB drivers can be utilized and operated by mobile devices and other external devices on a Windows computer. These include but are not limited to mice, keyboards, printers, external hard drives, speakers, and USB flash drives. If you need to download Google USB drivers, you can find them here.

Possibility of Android 14 Roll Out for the Google Pixel 3a and 3a XL?

Google will not roll out the Android 14 update to the Google Pixel 3a and 3a XL. Google’s Pixel 3a series is missing out on the Android 14 update despite being a popular device. As Google has said, the Pixel 3a series will no longer receive any updates or new features, let alone the release of Android 14.

Many major firms, including Google, follow a policy of scheduled updates. Despite Google’s reputation for speedy updates and dedication to a reliable interface, the company can’t guarantee indefinite support for its products.

Since its 2019 debut, Google’s Pixel 3a lineup has received the company’s usual steady stream of software updates. Typically, the policy will ensure that the device receives all major Android updates for up to three years after its initial release.

Released in 2019, the Pixel 3a series has already received updates up to Android 12, making it unlikely to receive the Android 14 update in accordance with this established trend. Moreover, the devices received their last and final security update back in September 2022, which means that there won’t be any more security updates for the devices too.

It is safe to assume that the Pixel 3a series will not receive the official Android 14 update due to Google’s update policy, normal update patterns, and the device’s hardware constraints.

Users interested in trying out the most recent Android release may want to look into custom ROMs, but they should be aware that doing so carries its own set of caveats and risks.


If you want to try out the latest Android OS version on your Pixel 3a and 3a XL, flashing the ported Android 14 is an option. Although it seems like the Pixel 3a and 3a XL won’t receive the official Android 14 update from the manufacturer, you can still enjoy most of the features and visual treatment with this ported version. However, if you encounter any bugs or stability issues, it’s important to report them to the respective forum.
