Always On Display is available only in Amoled display devices, and if I recall correctly, A10 does not have an Amoled display, so unfortunately no AOD.
1 . Begin with, Activating SAMSUNG Galaxy A10 and choosing Settings.
2. Following that, click on Lock Screen.
3. Thirdly, you need to select Always On Display.
4. Nextly, click on the switcher located next to Off.
5. Then, tap on Clock Style.
6. Here, you can pick Type and select one of Clock below, then Save your changes by clicking on Done.
7. Lastly, pick one of the available options to decide when you want to see the Always-on Display Option. You can also Switch On or Off Music Information! Then, go back by tapping on the Top Left Corner.
With the Android 9.0 (Pie) and Android 10 (Q) updates, Always On Display has been upgraded. It will not always display on the screen anymore; instead, it will only show when you tap your phone's screen. The "Tap to show" setting is enabled by default, but you can adjust the settings to show a continuous or timed AOD.
