Is it normal that my A129 Pro/ A129 Pro Duo becomes very hot when it’s recording?

Yes, it’s normal. As 4K UHD would cause a high load to the dashcam.

While please don't worry about it, there is a High-temperature Protection mechanism inside the cam,

A129 Pro front camera adopts heat discharge construction and the built-in sensor to detect the temperature of the main chipset. When the temperature of the chip reaches a certain degree, the device will automatically shut down to protect the dash camera from overheating.

If you still worry about overheating problems, we suggest you turn off the Wi-Fi, set the resolution as 2K during hot weather. 

Also, we suggest you use the SD cards of Samsung, VIOFO high endurance series, which can work better with the 4K dashcam.
