Heating Problem iPhone 12 & Check Fake or Original Phone

Hello abuhanifkj,

Thank you for reaching out to Apple Support Communities.

We were able to find this regarding your device being warm:

"Your device might get warm

You might notice that your device feels warmer when you:

• Set up your device the first time
• Restore from a backup
• Wirelessly charge your device
• Use graphics-intensive or processor-intensive apps, games, or features, including augmented-reality apps
• Stream high-quality video

These conditions are normal, and your device will return to a regular temperature when the process is complete or when you finish your activity. If your device doesn't display a temperature warning, you can keep using your device."

Additional details can be found here: If your iPhone or iPad gets too hot or too cold

To verify your device is genuine, please reach out to Appel directly. You can do so by going to Get Support

Cheers!
