📌 Important Notice: ELM327 v2.1 Chinese Clones Are Not Compatible

⚠️ This application does NOT work with most Chinese-made ELM327 v2.1 clones.
Many counterfeit ELM327 adapters (especially v2.1 models from China) have firmware bugs and communication flaws that prevent reliable operation with this diagnostic software. These devices may fail to connect, misreport data, or cause unexpected behavior.

❌ Do not purchase or use these clones if you expect reliable performance.

✅ Solution:
Use only genuine ELM327-based devices or certified OBDLink interfaces.
To verify your adapter’s authenticity, use the ELMScan Adapter Validator app (available on Google Play).
