I got this iPhone 12 Pro Max from a friend and the iPhone 12 pro max was working properly for a few days and I didn't get water, drop or any other damage in the iPhone. However, it is giving me the temperature warning ever since. I have tried to restart the device, shut it off, force restart it but it usually gives the warning after 5 seconds. I do not know what to do right now.

If it stays warm and will not cool down if you have turned it off for a while then most likely there is hardware issues going on. So you’ll most likely need to
Contact - Official Apple Support
Did you buy the phone from your friend? Tell him the phone has a hardware issue, which he likely was well aware of before selling the phone to you and you want your money back.
Of course, your friend will not tell you that they knew about this before they sold the phone to you.
The phone has problems. Your best bet would be to return the phone for a refund.
Otherwise, the phone likely needs a new battery or even more service attention at the Apple Store or an authorized Apple service shop. Service will run anywhere from about $100-400 depending on what is needed.
I had this issue with my iPhone too, It was however fixed by force restarting the device. But mine never actually got hot.
