“We’ll get in touch”
If the update has been confirmed for your own model, the smartphone will offer the update by itself at some point. You can also start the search manually in the settings. Usually the item is called “software update”.
The most noticeable changes are in the notifications. Notes on new messages from various chat apps are now prominently displayed in a separate area. A small profile picture and, if applicable, the name of the chat group are also displayed directly in the notification.
