FAQs
Q1. What’s the difference between regional versions?
Regional versions have important differences:
- China version: No Google services, different app store
- Global version: International software with Google services
- European version: GDPR compliance, EU-specific features
- Asian version: Regional network optimizations
Using the wrong regional version may cause connectivity or functionality issues.
Q2. Can I install European firmware on a Chinese device?
While technically possible, it’s not recommended because:
- Different network band support
- Potential baseband compatibility issues
- Lack of Google services on Chinese hardware
- Possible warranty implications
Always use firmware matching your device’s original region.
Q3. Why is the 165Hz refresh rate not always active?
The 165Hz refresh rate adapts based on:
- Content being displayed (static vs dynamic)
- Battery level and power saving settings
- Thermal conditions and device temperature
- Individual app compatibility and optimization
This adaptive approach balances smoothness with battery life.
Q4. How does the cooling system work during gaming?
The active cooling system includes:
- 20,000 RPM centrifugal fan for airflow
- Aerospace-grade cooling materials
- Multi-layer graphene and vapor chamber
- Smart temperature control algorithms
The system automatically adjusts based on gaming intensity and device temperature.
Troubleshooting (RedMagic 7 Specific)
- OTA installation fails: Ensure you’re installing the correct version sequentially. You cannot skip versions – install updates in order from your current version.
- Insufficient storage error: OTA updates require significant free space. Clear at least 5GB of storage and try again.
- Cooling fan not working: Check Game Space settings to ensure fan control is enabled. Clean vents from dust blockage and check for physical obstructions.
- Shoulder triggers unresponsive: Update to latest firmware and calibrate triggers in settings. Test in different game modes and applications.
- 165Hz refresh rate not available: Some applications and content don’t support ultra-high refresh rates. Check compatibility and ensure the feature is enabled in display settings.
- Battery draining quickly during gaming: This is normal during intensive gaming sessions. Use the included 65W charger for quick top-ups between sessions and enable battery optimization features.
