You will learn how the Mi A1 influenced the further strategy of Xiaomi, why it is often confused with other models of the Mi series, and where today you can find this rarity in working condition.

Official release date Xiaomi Mi A1: the chronology of events

Xiaomi Mi A1 was announced on September 5, 2017 at a special event in New Delhi, India, the first Xiaomi model to be released as part of Google’s Android One initiative to provide users with a “clean” Android without the manufacturers’ shells.

• 📅 September 5, 2017 — Official presentation in India.
• 🛒 September 12, 2017 — Launch of sales in India through the Flipkart platform and offline stores.
• 🌍 October 2017 – Entering global markets (including Russia, Europe and Asia).

Why India was the launch pad? By 2017, Xiaomi was actively building up its presence in the Indian market, competing with Samsung and local brands. Partnering with Google and releasing the Mi A1 was a strategic move: pure Android was more familiar to Indian users than MIUI, and the price of 14,999 rupees (about $230 at the time) made the smartphone available to a wide audience.

Technical characteristics of the Mi A1: why the smartphone became a hit

The Xiaomi Mi A1 wasn’t a flagship, but its hardware looked more than decent for the mid-range.

Particularly noteworthy is the dual main camera, a rare option for smartphones priced below $250 in 2017. Xiaomi used a solution with two 12-megapixel modules: one for standard shots, the other for portrait mode with the bokeh effect. The quality of photos in good lighting is still impressive, despite the lack of modern processing algorithms.

Another plus was the metal body with antenna lines stylized to the design of the iPhone 7. The smartphone looked premium, which was atypical for its price category. However, there was a drawback: the Mi A1 did not support wireless charging, and the GSM signal was sometimes lost when a bad hand grip was taken.

Mi A1 vs Mi 5X: What’s the difference and why it matters

As we mentioned earlier, the Xiaomi Mi A1 and Xiaomi Mi 5X are actually the same device with different software, but the differences between them go beyond firmware.

• 🤖 Operating system: Mi A1 ran on Android One (pure Android with guaranteed updates), and Mi 5X ran on MIUI (branded shell Xiaomi).
• 🌐 Regional availability: Mi A1 was sold globally (except in China) and Mi 5X was sold only in China.
• 🔄 Software Updates: Mi A1 got Android 9 Pie (the latest official update), while Mi 5X stopped at MIUI 10 (Android 7.1 Nougat).
• 📦 Set: The Mi A1 box had a Quick Charge 3.0 adapter, and the Mi 5X had a standard 5V/2A adapter.

Why is this important for customers today? Because in the secondary market, the Mi 5X is often referred to as the Mi A1, citing the same hardware. But the difference in firmware is critical: Android One provided more stable performance and received security updates longer. In addition, the Mi A1 supported Google Camera (GCam) out of the box, while the Mi 5X had to install it manually.

⚠️ Warning: When buying a used Xiaomi Mi A1, be sure to check the model through Settings → About Phone → Model. If you specify MI 5X, this is the Chinese version with MIUI, not Android One.

Previous articleHow Xiaomi and Google collaborated on the Mi A1

The Xiaomi Mi A1 project is the result of a unique partnership between Xiaomi and Google under the Android One program. Initially, Google’s initiative was aimed at budget smartphones for emerging markets, but by 2017 the concept has evolved: partner companies have gained more freedom in choosing hardware, and Google has the opportunity to promote “clean” Android on middle-class devices.

According to former Xiaomi vice president Hugo Barra, negotiations for the joint project began in the first quarter of 2017, with Google looking for a partner who could offer a competitive device at a price below $250, and Xiaomi needed to expand its presence outside of China, which resulted in the design and platform of the Mi 5X, but with a complete overhaul of the software part.

Interesting details of the development process:

• 🔧 The first Mi A1 prototypes were tested with Android 7.1 Nougat, but the final version came out on Android 7.1.2 with the promise of an upgrade to Oreo.
• 📸 The camera was originally developed with Google HDR+ support, but in the final firmware, this feature was disabled (it was only activated via modified versions of GCam).
• 🛠️ Xiaomi planned to release a version with 3 GB of RAM and 32 GB of memory, but the idea was abandoned due to the risk of cannibalization of sales of the Redmi Note 4.

Little-known fact: the first 500 Mi A1s were sold at auction in India for 1 rupee (about $0.015) as part of a marketing campaign, which had unique serial numbers and are now considered a rarity among collectors.

After September 2019, official support stopped, but enthusiasts continued to release custom firmware (such as LineageOS or Pixel Experience).However, due to limited specs (Snapdragon 625 and 4 GB of RAM), the smartphone did not receive stable builds of Android 10 and newer.
