Keep your mobile phone still and watch the weather and date.

Please check whether the date setting on your mobile phone is correct. If the date is correct, you can refresh whether the weather is normal.

Otherwise, it should be because the weather update is not timely because GPRS or WIFI is not turned on. For example, the last time you turned on data traffic, the weather forecast was updated for 5 days. After five days, it doesn't know what the weather is like, which means the date is wrong.

I also met the landlord today. First set the date to yesterday, then turn on the GPRS switch, and then change the date back later, and the problem will be solved.
