The yellow calendar does not show holidays.

My mobile phone suddenly stopped displaying legal holidays. /kloc-there were some in October, but there won't be any in the future. I suggest going to phone settings-Calendar-Show legal holidays, and click Open. If legal holidays are still not displayed after opening, you can back up the data files in your mobile phone, go to Settings-Other Settings-and click Restore your mobile phone, or you can take your mobile phone to the local official customer service center for testing and reinstall your mobile phone system.
