Acer Sospiro A15: The Budget Phone That Finally Brings Rear Displays to the Masses

The Rear-Display Design: A 1.88-Inch TFT Screen

The Sospiro A15's headline feature is a 1.88-inch TFT secondary display embedded in the camera block on the rear panel . With a resolution of 240×284 pixels, this small screen serves three core functions:

• Displaying time, date, and notifications
• Providing music playback controls
• Acting as a viewfinder for the rear camera, enabling high-quality selfies using the 64MP main sensor

The design is widely noted as being visually similar to the Xiaomi 17 Pro's "Magic Back Screen" approach, where a rear display sits alongside the camera array . However, the Sospiro A15 uses a simpler TFT panel compared to the AMOLED displays found on Xiaomi's flagships.

Target Market & Positioning

The Sospiro A15 is a budget/entry-level device explicitly aimed at Latin American markets . Pricing has not been officially confirmed, but multiple sources describe it as "affordable" or "cheap" . The choice of a Unisoc T615 chipset—which lacks 5G support—further confirms its entry-level positioning .

How It Compares to Other Phones with Secondary Screens

Xiaomi 17 Pro / 17 Pro Max (Sept 2025)

The most direct comparison. The Xiaomi 17 Pro uses a much larger 2.6–2.8-inch AMOLED rear display (called "Dynamic Back Display" or "Magic Back Screen") with a resolution around 976×596, running on a Snapdragon 8 Elite Gen 5 chipset at flagship pricing . The Acer Sospiro A15 mimics the same rear-display concept but at a fraction of the cost, using a smaller, lower-resolution TFT panel and entry-level Unisoc silicon .

Xiaomi Mi 11 Ultra (2021)

Xiaomi's earlier attempt used a 1.1-inch AMOLED rear display next to the camera bump, which was significantly smaller and less functional than both the Sospiro A15's 1.88-inch panel and the 17 Pro's 2.6-inch panel. The Mi 11 Ultra was also a premium flagship, not a budget device.

YotaPhone (2013–2017)

The original dual-screen phone pioneer used an E Ink rear display for reading and always-on info. The Acer and Xiaomi approaches differ by using a color TFT/AMOLED rear screen focused on notifications, music, and camera viewfinder use rather than e-reading.

Meizu 20 Infinity (2023)

Meizu experimented with a small rear screen next to the camera, but it was a limited-run design concept rather than a mass-market product.

Key distinction: The Sospiro A15 is the only budget-tier phone currently offering a secondary rear display. While Xiaomi, Meizu, and YotaPhone targeted premium or niche audiences, Acer has brought the feature to the entry-level segment, albeit with a smaller, lower-resolution TFT screen, no 5G, and limited regional availability .

Bottom Line

The Acer Sospiro A15 is not trying to compete with the Xiaomi 17 Pro on specs, performance, or screen quality. Instead, it is a proof-of-concept for the budget segment: can the rear-display feature—already validated by Xiaomi's flagship—find an audience among price-sensitive buyers in Latin America? For now, it offers the same core utility (notifications, music controls, selfie viewfinder) at a fraction of the price, with the obvious trade-offs in display quality, processing power, and 5G connectivity. If Acer's bet pays off, the Sospiro A15 could open the door for more budget-friendly dual-screen phones from other manufacturers.
