Symptoms

- Flickering worse at certain brightness levels
- Screen flickers right after a drop or bump

Likely causes
- CommonSoftware glitch in the display driverA rendering bug can cause visible flicker until a restart or update fixes it.
- PossibleLoose internal display connector after a dropPhysical impact can loosen the ribbon cable connecting the screen.
- PossibleFaulty charger causing electrical interference while chargingA cheap or damaged charger can introduce power fluctuations.
- Less commonAging or failing display panelVery old devices can develop panel issues independent of any single cause.
What to do
- Restart the watch to rule out a temporary software glitch.
- Update the watch's firmware to the latest version.
- If flickering only happens while charging, try a different charger and cable.
- Note whether flickering started right after a drop, which points to a loose internal connection.
- Lower or raise brightness to see if flicker is tied to a specific brightness level, which can indicate a display driver bug.
- Avoid continuing to use the watch heavily if flickering worsens quickly, since it can be a sign of a failing panel.
When to call a pro
If flickering persists after a restart and update, especially after a drop, the display or its connector likely needs professional repair.
