A recent Android 11 update causes a weird issue on some OnePlus phone models. After the update, many OnePlus phones start showing the 24-hour time format on the lock screen, even if you disable it. The wrong time format issue affected the OnePlus 8, OnePlus Nord, and OnePlus 7T units. Here is an easy workaround to fix the problem.

If you cannot change the 24-hour clock on the lock screen of your OnePlus phone after the Android 11 update, then you are not alone. Many OnePlus 8/8 Pro/8T/7T and OnePlus Nord users report about it. It seems that the issue is due to a bug in the OnePlus OxygenOS 11 builds and easy to fix.


Here is a workaround to fix the wrong time format (24-hour clock even in 12-hour AM/PM mode) on the OnePlus phone.
