Performance
Under the hood, the Ulefone S1 runs on Android 8.1 Oreo (Go edition), an optimized version of Android designed for devices with limited resources. The MediaTek MT6580 chipset, combined with a quad-core 1.3 GHz Cortex-A7 CPU and Mali-400 GPU, powers the phone’s operations. With 1GB of RAM and 8GB of internal storage—expandable via a microSD card—users will likely find the device most suitable for basic tasks, as running multiple apps or heavy applications may lead to performance bottlenecks.
