Identified technical problems
Camera problems
Even before the official release of the device, reviewers reported problems with auto focus and excessive skin smoothing in photos. Samsung has taken corrective action, but on models equipped with the Exynos processor, autofocus problems persisted even after the release of a dedicated update.
Problems with GPS
Users of the version equipped with the Snapdragon processor reported difficulties in getting a stable GPS connection.
Problems with Exynos processor
Models using the Exynos processor have suffered from device overheating issues.
Problems with the display
After one software update, some users reported the appearance of a green tint to the screen.
Problems in the Indian version
A specific display issue was reported in India - after updating to One UI 4.01, a vertical line appeared on the screens of some devices. The problem affected devices whose warranty period has already ended. Samsung India has classified these cases as user-induced damage, setting the cost of replacing the screen at around 16,000 Indian rupees. The situation has caused significant dissatisfaction among users, with about a thousand people reporting the problem via social media, and some deciding to take legal action. To date, Samsung India has not officially acknowledged the existence of this problem.
Security features and special functions
The upday news aggregation app, developed in partnership with Axel Springer SE, was pre-installed on European S20+ models. This application could send notifications to users.
Special editions of the software
Samsung tailored the software to the specific requirements of different markets and partners, as exemplified by the introduction of special versions of the system for specific operators or regions. This approach demonstrates the flexibility of the manufacturer to adapt to local requirements and user needs, while maintaining consistency in the core functions of the operating system.
