A non-responsive touch panel on your Redmi Watch 4 is often caused by software glitches, low battery, or physical damage. Temporary system freezes, water exposure, or an unresponsive display driver also will lead to this issue.
To resolve the unresponsive touch panel issue on your watch, please refer to the following steps:
1. Press and hold the side button for about 15 seconds until the watch reboots. This can fix minor software freezes and restore touch functionality;
2. Ensure the battery isn’t critically low. Connect the watch to its charger and wait a few minutes before trying the touchscreen again;
3. Dirt, moisture, or sweat can interfere with touch sensitivity. Gently wipe the screen with a microfiber cloth and ensure it’s dry;
4. Open the Mi Fitness APP, check for software updates, and install them if available. Bugs causing touch issues are often fixed in updates;
5. If the problem persists, reset the watch via the Mi Fitness APP. Note that this erases all data;
6. If none of these steps work, contact Xiaomi Support for further assistance, as the issue requires hardware repair.
