: After a major update, the system performs background optimizations that cause temporary heat. Recommendation
: Turn off the screen and charge the device overnight after a successful update to let these processes complete. Disable RAM Expansion
: This feature uses internal storage as virtual RAM, which can increase heat if storage is nearly full. Disable it via Settings > About device > RAM Manage Background Apps
: High processor usage from too many active apps often leads to overheating. Close unused apps and check Settings > Battery to find power-hungry processes. Avoid Usage While Charging
: Using the phone for gaming or video streaming during fast charging is a primary cause of overheating. Downgrade Firmware

Fix:
Let's address the elephant in the room. Search any forum for "Oppo A78 4G hot," and you'll find users reporting the phone warming up during 4G video calls or while playing Mobile Legends.
Here’s the firmware truth: The A78 4G runs on the Qualcomm Snapdragon 680—a chip built on a 6nm process. It’s efficient, but not flagship-cold. The phone’s firmware aggressively manages thermal throttling. When you feel heat near the camera module, the firmware is actually working overtime, doing three things:
The latest firmware updates (versions ending in A.17 and above) introduced a more aggressive "Smart Charging" algorithm. While older firmware let the phone hit 44°C before throttling, the new firmware starts pulling back at 41°C. The result? The phone feels warm, not scorching—but you lose about 8-10% of peak gaming performance.
If you’ve updated to the latest firmware (A.17) and your OPPO A78 4G is still too hot to touch, the issue might be physical:
| Symptom | Firmware Related | Hardware Related | |-------------|----------------------|----------------------| | Heat only during 33W charging | Yes (charge IC logic) | Possibly a bad battery | | Heat while idle (screen off) | Yes (wakelock bug) | No | | Heat concentrated near camera | No | Faulty mainboard | | Heat plus random reboots | Yes (kernel panic) | No |
If you suspect hardware, visit an OPPO service center. The A78 4G’s thermal paste application is known to be inconsistent in early batches.
