System

The BLU F91 5G comes with Android OS v11.0 out of the box, but it is upgradable to the next OS. Android is closely integrated with various Google services, such as Google Maps, Gmail, and Google Drive, which makes it easy for users to access and manage their data across multiple devices. The F91 5G utilizes Mediatek Dimensity 810 SoC (System on a Chip). This powerful octa-core processor is capable of handling complex tasks and running multiple applications simultaneously.

The F91 5G utilizes Mali-G57 MP4 GPU. A GPU (Graphics Processing Unit) is a specialized chip that is primarily designed to handle and accelerate the processing of graphics and visual data. It is responsible for rendering images, videos, and animations on a smartphone screen. ARM Mali GPUs are widely used in mobile devices and have a good reputation for performance and power efficiency. They offer competitive performance and power efficiency, making them suitable for a range of applications, including gaming, multimedia, and user interface rendering. We use AnTuTu app to measure general processing performance. AnTuTu Benchmark is the most popular benchmark app for Android phones.

Display

The 6.8 inch phone comes with IPS display. The IPS display provides enhanced features, such as optimal viewing angles, color accuracy, invariable color reproduction and better power consumption. The 6.8 inch display should be large enough to provide a comfortable viewing experience for your needs, whether it's reading text, browsing the web, or watching videos. The size of the screen is measured diagonally, from corner to corner. A larger screen typically requires more power to illuminate, which can impact battery life.
