Galaxy A57 5G Features Certified Eye Care and IP68 Rating
The Samsung Galaxy A57 5G comes equipped with a 6.7-inch screen measured diagonally in the full rectangle, or 6.6 inches accounting for the rounded corners and the camera hole. Tesco Mobile notes the display has received Eye Care Certification by SGS based on its blue light reduction capabilities. The handset carries an IP68 rating, determined by lab test conditions involving submersion in up to 1.5 meters of freshwater for up to 30 minutes.
Rear Wide-Angle Camera Uses 50-Megapixel Resolution
Photography capabilities center on a 50-megapixel resolution available exclusively on the rear wide-angle camera. The software suite integrates Best Face functionality for Motion Photos and continuous captures within a 10-second window. Edit suggestions support JPG, PNG, and GIF formats, though output quality depends heavily on the original image condition. Imaging features include Gemini and Bixby integrations, the latter supporting nine languages.
Battery Capacity Reaches 4,905 mAh with 5G Connectivity
Power management relies on a typical battery capacity tested under third-party lab conditions, yielding a rated minimum capacity of 4,905 mAh. Independent assessments conducted by UX Connect Research between January 8 and January 18, 2026, in the UK using pre-release SM-A576 units under default settings evaluated performance on LTE and 5G Sub6 networks, omitting 5G mmWave testing. Connectivity relies on optimal 5G network conditions, alongside Quick Share capabilities supporting file transfers up to 10 GB per file and a maximum of 1,000 files simultaneously with devices running Android OS 10 or higher.
