Samsung Galaxy A37 and Galaxy A57 Leak Reveals Specs, Price and 2026 Launch Plans

Samsung Galaxy A37 and Galaxy A57 leak hints at higher mid-range prices
Samsung Galaxy A37 and Galaxy A57 leak suggests that Samsung’s upcoming mid-range smartphones may arrive with noticeable price increases in 2026. Recent reports indicate that the company is preparing both devices with upgraded hardware, improved displays, and larger batteries. However, the leaked pricing also indicates that the cost of Samsung’s mid-range lineup could rise compared to previous generations.
Samsung’s Galaxy A series has traditionally offered a balance between performance and affordability. But if the latest leaks are accurate, the upcoming Galaxy A37 and Galaxy A57 could move closer to the premium mid-range category.

Expected specifications of Samsung Galaxy A57
The Samsung Galaxy A57 is expected to be powered by the Exynos 1680 processor, which should provide better performance and efficiency compared to previous A-series chipsets. The device may feature a 6.7-inch Full HD+ AMOLED display with a 120Hz refresh rate, offering smoother scrolling and improved viewing experience.
In the camera department, the phone is rumored to include a 50-megapixel primary camera with optical image stabilization, allowing users to capture more stable photos and videos. The smartphone may also pack a 5,000mAh battery that supports 45W fast charging, which should help users quickly recharge the device.
Samsung Galaxy A37 specifications and features
The Galaxy A37 is expected to be powered by the Exynos 1480 processor. While it may sit below the A57 in the lineup, it is still expected to feature a high refresh rate AMOLED display. The phone could also include a 5,000mAh battery, ensuring all-day usage for most users.
Although detailed camera specifications have not been fully confirmed yet, the device is likely to maintain Samsung’s focus on versatile camera systems within the A-series lineup.
Expected price and launch timeline
According to the leak, the Galaxy A37 could be priced at around $460, which roughly converts to about ₹38,000. Meanwhile, the Galaxy A57 may launch at approximately $570, translating to around ₹47,000.
Both smartphones are expected to launch globally in 2026, with availability likely expanding to major markets including Asia and India shortly after the official announcement.
If these prices turn out to be accurate, Samsung’s mid-range smartphones may soon compete directly with premium mid-range devices from other manufacturers.

Google Pixel Tablet Android Desktop Mode: A New PC-Like Experience Coming to Android
Introduction
Google Pixel Tablet Android Desktop Mode is set to bring a major productivity upgrade to Android devices. Google is reportedly working on a desktop-style interface that allows Pixel devices to function more like a traditional computer when connected to an external display. The feature aims to improve multitasking, window management, and overall productivity for users who want a PC-like experience from their Android devices.
This development signals Google’s effort to compete with existing mobile desktop platforms such as Samsung DeX and to make Android more capable for work and multitasking.
Desktop-Style Interface for Pixel Devices
The upcoming desktop mode introduces a familiar computer-style interface when a Pixel device is connected to an external monitor through USB-C. Instead of simply mirroring the phone or tablet screen, the system launches a dedicated desktop environment.
Users will see a taskbar at the bottom of the display along with resizable app windows. Applications can run simultaneously in overlapping windows, allowing users to move, resize, and manage them similar to a traditional desktop operating system.
This feature is expected to work particularly well with the Google Pixel Tablet, as the larger display and tablet-focused software make it ideal for productivity tasks.

Improved Multitasking and Productivity
Android’s desktop mode focuses heavily on multitasking improvements. Users will be able to open multiple apps at the same time and switch between them quickly using the taskbar.
The system also supports external accessories including a mouse and keyboard, enabling a full workstation-like setup. This means tasks such as document editing, browsing, and media management can be handled more efficiently.
The interface is designed to maintain Android’s flexibility while offering a more structured desktop environment when needed.
A Step Toward a More Powerful Android Ecosystem
The introduction of desktop mode highlights Google’s long-term strategy of making Android more versatile across devices. By enabling a PC-like environment on Pixel hardware, Google could expand Android’s role beyond smartphones and tablets into productivity-focused computing.
If fully implemented, the feature could transform devices like the Pixel Tablet into compact productivity machines capable of replacing a basic laptop for many everyday tasks.
