The Redmi 4a is a budget-friendly smartphone that packs a punch. It was announced in August 2017 and is a great option for those on a tight budget.
One of the standout features of the Redmi 4a is its 5-inch HD display. This means you'll get crisp and clear visuals without breaking the bank.
The Redmi 4a is powered by a 1.4GHz Qualcomm Snapdragon 425 processor, which provides smooth performance for everyday tasks. This processor is more than capable of handling everything from social media to email and browsing the web.

Design and Build
The Redmi 4A's design is a mixed bag. It has a plastic body with a rear-facing mono speaker, which might seem old-fashioned compared to newer phones.
The plastic body has its advantages, though - it's more resistant to creaking and flexing, and it doesn't get as warm as some metal phones.
The Redmi 4A feels great in the hand, with a 5in display and reasonably slim bezels on either side. It's 70.4mm wide and 8.5mm thick, which is comfortable to hold.
The screen is a 5in HD (1280×720) panel, and at this size, it's perfectly clear.

You can store up to 128GB of storage on a microSD card if you only have one SIM card.
This is a great option if you want to expand your storage without having to use a SIM card.
Xiaomi
Xiaomi's design philosophy is centered around creating products that are both functional and visually appealing. They often partner with renowned designers to bring a touch of elegance to their devices.

Hardware and Performance
The Redmi 4A's core hardware is powered by a quad-core Snapdragon 425 processor clocked at 1.4GHz.
This processor is paired with 2GB of RAM and a generous 32GB storage, which can be expanded up to 128GB using a microSD card.
The Redmi 4A's performance is suitable for casual gaming, browsing the web, and firing off emails, but it's no speed demon.

In Geekbench 4, the Redmi 4A clocked 670 points single-core and 1775 multi-core, outperforming the Vodafone Smart N8.
The Redmi 4A's graphics performance is also decent, recording 14fps in the GFXBench T-Rex test, which is higher than the Vodafone Smart N8.
The 3120mAh battery should easily last a day, and possibly more, depending on how you use your phone.
The Redmi 4A supports dual-SIM capability, infra-red blaster, Wi-Fi, Bluetooth 4.1, and GPS, but lacks NFC and a fingerprint scanner.
Display and Camera
The Redmi 4A's display is a standard affair, with a 5-inch screen that gets the job done. It's not particularly noteworthy, but it's a decent size for a phone of this price.
The rear camera is a 13Mp lens with single-LED flash, which is okay for the price point. However, in low-light conditions, it can struggle to capture a lot of detail, and HDR mode can make things worse.
You can shoot full-HD video, which is a nice feature, and the default is HD, which is still pretty good. The 5Mp selfie camera is not the best, but it's useful for quick snaps and video chats.

12-inch 7cm 5HD Display

The Redmi 4A's display is a real treat for your eyes. It has a 12.7cm (5) fully laminated display.
This display is packed with pixels for HD resolution. The screen also has Read mode, which reduces eye fatigue by minimizing blue light rays.
You can adjust the colour temperature to your liking - warm, standard, or cool. This feature allows you to customize the display to suit your preferences.
The display has a pixel density of 296 ppi. This is a measure of how many pixels are packed into a small area of the screen, resulting in a sharp and clear image.
Cameras & Photography
The smartphone's camera is a 13 MP lens with f/2.0 aperture and autofocus, capable of recording 1080p video at 30fps. It's not the most advanced camera, but it gets the job done.
The rear camera is okay at this price, and it's surprising how well it handles low-light conditions without a flash. Lighting up the scene and clearly differentiating between blacks, it's a decent effort.
However, in normal daylight conditions, the camera loses a lot of detail, resulting in blurring. This is amplified by HDR mode, which doesn't make a huge difference. On a sunny day, though, colours are vibrant.
The camera app is pretty decent, offering various scenes and standard shooting modes. You can even use the volume buttons to trigger the shutter, which is a handy feature.
The Redmi 4A can shoot full-HD video, but the default is HD. The 5MP selfie camera is not the best, but it's useful for Snapchat selfies and video chats.
