Pokemon GO makes my cell phone overheat

Hey, guys,
for about two months (maybe a little less) every time I use Pokemon Go on my Samsung Note 9, it overheats too much. Sometimes it even burns on my hands.
I have a friend who also plays Pokemon Go and says that he also warms up his phone but not as much as mine.

Do you think it's due to the latest Pokemon Go updates? Or maybe it's a problem with my mobile?
I'm worried because I'm afraid that it's a failure of my mobile, although before it didn't happen and due to the latest updates of Pokemon Go is when my problem started.
Also, every time I close the game, my phone cools down and returns to its normal temperature.

Is anyone else the same?

Thank you.

este cel mai urat joc din lume si cel mai periculos, multi au murit din cauza acestui joc! Translate

shouldn't happen

My phone also became overheat sometimes when I play longer. I think it's normal.
