The "second" display of clock doesnt work properly

When i use the app to create custom digital clock with time, i include second too, but it sometimes doesnt run, or run slower than the actual time of my phone. The “minute” also has the same issue.

Seconds in KWGT are a bad idea. They technically work, but they will lag and freeze because Android limits how often a widget can refresh. This is why your minutes might lag too.

My advice:

Use KLWP: If you really need smooth seconds, use Live Wallpaper instead of a widget.

For KWGT: Stick to HH:mm. It’s way more stable.

Fix Lag: Disable Battery Optimization for KWGT in your phone settings so Android doesn’t put it to sleep.
