That depends on what kind of update it is. Quick bug fixes usually roll out every two to three weeks, so if something is not working quite right, chances are it will be patched up pretty soon.
When it comes to new features and improvements, those are typically released once a month. That means fresh tools, better performance, and a smoother experience are always on the way.
You do not have to wait long. Whether it is a fix or a feature, your phone is always getting better behind the scenes.
