Finally, after a period in the testing phase, you can now update your iPhone to the latest version of iOS: 12.4. This will be the last update of iOS 12, before the arrival in September of the expected iOS 13.
The most outstanding novelty of this improvement focuses on the new mobile-to-mobile data transfer system. If you buy a new terminal, passing all the data is now much easier.
Apple has always been concerned that starting a new device is as simple as possible. We are already checking it with the Apple Watch, Apple TV, etc., where you only have to have your iPhone close by when you start one of these devices for the first time, so that your data (Apple id, passwords, wifi, etc.) are automatically transferred to your new gadget with the apple.
Until now, when you changed terminals, you made a backup in icloud or on your computer using iTunes, and you restored said copy in your new terminal. A simple and safe job, but you needed to have space available in the cloud or a computer for this transfer. With this new enhancement, all of this is no longer necessary. Simply power up your new phone with the old one nearby, and the system will detect your old iPhone wirelessly. If you want, connect the two devices using the lightning cable and said transmission will no longer be via bluetooth or direct WIFI, but via cable. Obviously, it will ask you for the password of your Apple ID in the new terminal, configure the access code, and if you want, Face ID or Touch ID depending on the model.
From here, you have the option to transfer your data from iCloud, or use the new direct transfer option. You no longer need to have a copy in the cloud, (although it is highly recommended to do one daily, automatically) or fiddle with your computer. You will have all your photos, applications, documents, passwords and settings in your new terminal exactly the same as in the old one. That simple.
It should be noted that this transfer does not include the entire volume of data that the applications occupy. Only the application header is transferred. Once the new mobile is operational, it automatically installs the applications that you had on your old iPhone from the Apple Store.
The only downside is that you need both terminals to be updated to iOS 12.4. In the old mobile there will be no problem, you will worry about having it up to date, but in the new terminal, until the end of August Apple does not assure you that the new phones already come with this update.
