How To Change The Lock Screen Clock on Samsung Galaxy S8

If the Galaxy S8 or the Galaxy S8+ is your first Android smartphone, it is likely that you will be overwhelmed with the sheer number of features that the handset comes with. A frequent question that I have seen many new Galaxy S8 owners ask is how to change the lock screen clock.

Now, unlike other Android devices, there are two different lock screen clocks that one can be talking about here. First, there is the Always On Display, which is enabled by default on the Galaxy S8 and S8+. Taking advantage of the OLED display, Samsung offers an Always On Display mode on the Galaxy S8 in which the display will show the time and an unread notification icon from a few selected apps.

Now, if you want to customise this lock screen clock, that can be done from the Settings menu. However, if you want to customise the clock on the ‘actual’ lock screen i.e. on the screen that shows up when you wake up the device and you are yet to unlock the device, well that’s not possible sadly. While previous versions of Android featured lock screen widgets, it is not possible to add additional widgets on the S8’s lock screen. One has to make do with the four widgets that Samsung has placed on the lock screen by default: clock, music, calendar, and alarm. By default, the lock screen will automatically switch to the clock widget and one has to swipe to the left to access the other widgets.

If you want, you can disable the additional ‘FaceWidgets’ or re-order them as well. For this, head over to Settings -> Lock screen and Security -> FaceWidgets.

Nonetheless, if all you want to do is change the clock style on the Always On Display of your Galaxy S8 or Galaxy S8+, here’s how to do so.

Step 1: Head over to Settings -> Lock screen and Security -> Always On Display. 

Step 2: You can now customise Always On Display according to your liking. This includes being able to change the lock screen clock style to world clock or an analogue one or even switch to Edge clock. Additionally, you can also set the Always On Display to show a custom image or the calendar.

Remember that using the Always On Display will have a negative impact on the battery life of your Galaxy S8 or S8+. So, it is recommended that you turn the feature off if you want to prolong the battery of your handset. You can also automatically turn on Always On Display when the phone is charging via an app.


If you are not really fond of the stock lock screen on the Galaxy S8, you can try a third-party replacement app from the Play Store. But remember that they won’t play well with the iris scanner and will also act finicky at times.

    New S8 owner. Surprised there’s no way to change the crappy 2 digits on top of 2 digits clock (on the real lock screen; not talking about always on display). I just don’t like the appearance so changed immediately on AOD. Oh well 🙁

    • Spark

      Actually there is. Settings App->Lock Screen & Security->Always on display->Digital Clock->Clock Style->Pick the one you like.

      • Ceitinn

        He clearly said not talking about always on display! You can’t change that setting unless you activate AOD and if you deactivate it the clock reverts to the 2 up, 2 down setting.

      • Angela Waldo

        That only changes it on the AOD. I’m with maclifter, I very much dislike the way the default clock looks.

      How do I change the clock themes on the lock screen:

      1. Go to samsung themes and find the themes you like to use for the clock shape/font/colors on lock screen, download and apply it, this will be the clock you use (for me i use the rainbow colors clock). But the clock will be back to the default samsung clock when you check it, maybe a bug at the phone software.

      2. Go back to samsung themes and this time find a themes that you must buy to apply it, but we never actually paid it, just press the free trial button, when it finish download and apply the themes, go back to the samsung themes and press the stop trial button.

      3. Somehow it will fix the bug at step no. 1 and the clock will be change to themes that you apply at the first time. I warn you if you change the wallpaper at the lockscreen, it will change back to the default samsung clock, so pick a wallpaper before you do the step no. 2.

      I find this method by accident at my S8+, i hope samsung fix this bug eventually, btw this is a great phone and i love to use it as my daily main phone. Sorry for my english and i hope this is the answer that you asking for.

    I really hate this weird 2 digits top 2 digits bottom design. Why can’t we have the simple HH:MM clock? (and I’m talking about the lock screen, not the AOD screen)

  • John Doe

    First of all, not all Samsung phones that are running Nougat have the AOD feature. My J7 2016 certainly does not support it and the option isn’t available in my settings.

    Second of all, the Lock Screen Clock can not be changed. Period. That’s the stock clock Android 7.0 has. The only option is use a lock screen app, or change your theme which sometimes (not all of them do this) change the clock style.

    This is the absolutely the most retarded design choice I have ever seen for something so simple. A friggin clock that isn’t presented correctly. It’s like Google is trolling us.
