Frequently Asked Questions (FAQs)

Q1. Why is my dual camera not working properly after update?
The dual camera system with 2x optical zoom requires specific calibration. Flash the stock ROM and recalibrate through hardware test menu (##6484## → Camera Test). This often resolves focus and portrait mode issues.

Q2. Can I upgrade to Android 9 or higher on Mi 5X?
No, Android 8.1 Oreo was the final official Android version. However, there are custom ROMs like LineageOS 16 (Android 9) available through TWRP if you want newer Android versions.

Q3. What’s the difference between Mi 5X and Mi A1?
They share identical hardware, but Mi 5X runs MIUI while Mi A1 runs Android One. You can cross-flash between them, but camera performance may vary due to different camera processing algorithms.

Q4. Why is my device lagging with 4GB RAM?
The Snapdragon 625, while efficient, may struggle with newer MIUI versions. Consider using Lite mode or flashing a lighter custom ROM for better performance.

Device-Specific Troubleshooting
