A beta that, like the previous ones, can be downloaded without having to be a developer.However, the equivalent version of the public beta remains to be launched in the coming days.In any case, this helps us to see the new tweaks that Apple has made in the iPhone operating system.We remember that iOS 16 will not be officially available until September, but in the meantime we can see what this new version will be like thanks to the betas.In the latter we have seen some interesting changes in the interface, as well as the definitive opening to functions announced at the last WWDC 2022.The third beta of iOS 16 served at the time to improve aspects already present in previous versions or integrate privacy functions such as the well-known Lockdown.This beta follows the same line of visually improving the system and correcting errors present in previous betas (although it is still not exempt from possible bugs).Among the most relevant novelties we find changes in iMessage that not everyone will like and that is, after allowing in this version to edit and delete messages already sent, in this fourth beta an editing history is shown and the time to delete messages is reduce from 15 minutes to only 2.We also find more intuitive actions in the settings regarding configuring the home and lock screen, also adding new possibilities for background blurring or creating custom wallpapers with color gradients.This action can be carried out from the settings or from the lock screen itself when editing.Also in the settings we find a new notification configuration for the lock screen.In this beta there is already the possibility of displaying them in the form of a Count at the bottom, showing only the number of notifications, in Group format, being able to see the main grouped notifications or in List format with an aesthetic more similar to that of iOS 15 and earlier versions.Although if there is an important novelty, although it is not yet visible to the user, it is to open the door to the lock screen widgets that are updated live.These were presented at the WWDC with practical examples such as the journey of an Uber to reach the destination or the live score of a football match.It has been in this beta in which Apple already opens the tool so that developers can already test their own widgets.Regarding widgets, and no matter how small the change, the volume bar is finally integrated when using Apple Music from the lock screen.In addition, the texts are displayed larger so that they can be better visually appreciated.We also see something that will help optimize iPhone storage, since the Health app now shows how much space each of the measurements that are made takes up, including those that come from the Apple Watch.Other minor changes are found with the new Home and CarPlay wallpapers.Precisely in the Apple system for vehicles, novelties were missing, no matter how small, since Apple only advanced at WWDC that in the future there will be vehicles with CarPlay as their own navigation system.So, after all, this fourth beta serves to polish the details of an iOS 16 that is getting closer and closer.As we said at the beginning, the second public beta based on this fourth for developers will arrive in a few days, so if you are testing this version you will still have to wait to test these changes.If you are one of those who prefers to wait for the official, the countdown has already begun.Share iOS 16 continues to get ready for your iPhone: its main novelties in the fourth beta for developersMore Sites You'll LikeSee more articlesSee more videosAt Xataka Móvil we talk about...
