My phone is Lenovo A820T, and the lock date is different from the phone desktop? Why is this? The mobile phone desktop is Wednesday, but the lock screen is Thursday.

Dear Lenovo users, hello! Too much cache in mobile phone may cause the system to run slowly. The time given by the system is correct, but the time displayed on the desktop is not refreshed in time. You can clear the cache to see if the problem still exists, or you can back up the data and restore the factory settings! At the same time, it is not recommended that you install or run too much software on your mobile phone at the same time. Thank you for your support of Lenovo products and wish you a happy life!
