Disable RAM Expansion: Navigate to Settings > About Device > RAM and turn off the RAM expansion feature, as it can sometimes increase system stress and heat.
Update Apps: Ensure all apps are updated via the Google Play Store to prevent compatibility-related overheating. 2. Updating via Official Tools
If you need to refresh the system software to fix bugs, use the official methods:
OTA Update: Go to Settings > About Device > ColorOS to check for the latest stable version.

I have interpreted "hot" to cover two main angles: 1. Solving overheating issues and 2. The "hot" (popular) firmware versions used for bypassing FRP or downgrading to remove bloatware.
Paradoxically, some users on A.15 reported worse overheating than A.13. If you are one of them, you can downgrade.
How to downgrade safely:
Firmware is the low-level software that controls the hardware—CPU governors, charging IC (integrated circuit), and battery management. When the firmware is buggy, three things happen:
OPPO has released incremental updates (A.11 → A.13 → A.15 → A.17) specifically addressing thermal throttling. If you are running firmware version A.09 or earlier, your phone will run hot by default.
If you are downloading the firmware to fix a bootloop or heating issue, follow this method using the MSM Download Tool (for Unbricking) or SP Flash Tool (if you have a Scatter file).
