Why does the Xiaomi 17 Ultra experience a brief, localized screen flash when touched or plugged into the charger in winter?

Question

Accepted Answer

If you notice a brief and localized screen flash when touching the Xiaomi 17 Ultra or plugging in the charger during winter, please refer to the following explanation:
1. In winter, the air is usually dry, which makes it easier for your clothes or body to accumulate static electricity. When you touch the phone or connect the charger, the static charge could be instantly released through the device interface.
2. This sudden discharge can cause a very short and minor interference to the display circuitry, which can appear visually as a quick white flash on the screen.
3. The Xiaomi 17 Ultra is designed with electrostatic discharge (ESD) protection in mind. It is equipped with internal protection circuits that effectively absorb and dissipate everyday static electricity. This brief phenomenon will not affect normal functions, safety, or the lifespan of the device.
4. To reduce the likelihood of this occurrence, you can touch a wall or another grounded metal object before handling the device to release static electricity. Using a humidifier indoors to increase air humidity can also help.
5. If the screen continues to flicker, does not return to normal, or shows other abnormalities, please contact official after-sales service for professional inspection.
