On a rooted Android or Linux-based Exynos device, check:
For example, the “A2N Kernel for Galaxy S8 / S8+ (Exynos)” explicitly offers “Thermal Control” and “Charger Control” options that allow you to override the default thermal behaviour. Similarly, the Odroid XU4 board (which uses an Exynos5422 SoC) received device‑tree improvements to “enable proper USB 3.0 regulators” and to “set over‑heat and over‑voltage thresholds”.
Windows is notorious for automatically installing the wrong USB driver for Exynos devices in PID 0x4000 mode. Instead of the correct “Samsung USB Driver for Mobile Phones” or the libusb -based driver (for Zadig), Windows may assign a generic WinUSB or even a modem driver. This leads to failed control transfers and the host resetting the port—reported as “hot.” exynos usb device4000 hot

Boot into Safe Mode (Hold Power, then long-press Power off -> Safe Mode). If the heating stops, a third-party app is causing the conflict. Open Device Manager on PC. On a rooted Android or Linux-based Exynos device,
Allow your phone's battery to drain completely until it powers off. Charge it uninterrupted to 100% while keeping the device powered down. This resets the battery fuel gauge and clears temporary thermal trip-wires in the Exynos kernel. When to Seek Component-Level Repair
If the issue was a temporary controller latch-up, clearing the residual power can reset the chip status. Ensure the device is cool to the touch. Reconnect the battery (if it was disconnected). Instead of the correct “Samsung USB Driver for
Jax, a struggling VR-DJ, lived in a "micro-loft" where his only luxury was a high-fidelity haptic suit. His career was flatlining until he stumbled upon the Exynos 4000 at a black-market tech swap. Unlike standard drives, this one pulsed with a low, amber light—a sign of the proprietary 4nm architecture buried inside.
