Just saying "heating issue", without providing any information.. ie:
Did the device shut down due to temperature?
Did you get any warning about the temperature?
Do you know what peak temperature the device got to?
It's perfectly normal to see the internal temperature get to the 40s C.
While it's normal for your phone to heat up occasionally, the optimal internal temperature for cell phones ranges from 32°F to 95°F (0°C to 35°C), and temperatures between 96.8°F to 109.4°F (36°C to 43°C) are still considered normal. Anything above this is unsafe and you should take steps to cool down your phone.
