| The phone has good battery life and decent charging speed. The functionality is basic with limited sensors. The software is outdated and lacks updates. The design is sleek but lacks durability. The screen is average with low resolution. Performance is slow and not smooth. The camera quality is poor. The cost is low but not worth it. Overall, the phone has more cons than pros. | ||
