Heat issues on this chipset are rarely caused by a single "broken" driver. Instead, they usually stem from a combination of hardware bottlenecks and software load: Unisoc Tiger T117 - Helpix
The Unisoc UMS9117 driver is not a product you buy; it is a contract you trust. It is the invisible concierge that wakes up your display when you reach for your device, decodes the latest Netflix series without stuttering, connects your microphone during a crucial job interview, and goes back to sleep having consumed minimal power.

I’ve noticed that the device is exhibiting classic signs of overheating, specifically when the modem is under load (heavy data usage or weak signal areas). I ran some diagnostics, and the CPU temperature spikes rapidly, pushing the thermal zone limits. It seems the driver or firmware configuration for the power management is a bit too aggressive, or simply unoptimized, causing the "hot driver" state where the modem refuses to downclock even when idle.
