There are many issues in the AOD that need to be fixed or improved, such as:
- AOD is very dim most of the time. Very annoying when a new notification is received.
- The music currently playing is not shown
- No weather info is shown
- No steps info
- As you mentioned no GIF or Emoji (a very cool feature in OnePlus phones) support
These problems are found in all ASUS devices, unfortunately. They have to invest more in the AOD.
Thanks
