Android 12 introduced several innovations such as the new graphical interface based on Material You, but also a renewed notification center that also brings with it a new toggle. This is a toggle called the Internet, which groups together the settings regarding both the wi-fi and the data connection.
This change requires an extra step in managing connections, and this is not liked by many users. Apparently, Sony also thinks like them in fact, with the update to Android 12, the Japanese company has decided to keep the two toggles separate.
The toggles remain separate on Android 12, but there is a bug
As noted by a Redditor, / uChiron_89, who updated his Sony Xperia to Android 12, this still has separate toggles, unlike what Google did with its Pixels. However as the user pointed out, due to a bug, these toggles are not accessible out-of-the-box. You will then need to perform a factory reset to enable them.
If you own an Xperia 1 III or an Xperia 5 III, the only two updated devices for now, and you don’t see the separate switches, you can try resetting your phone to factory settings. If, on the other hand, you have not yet updated your device, you can do so via the item in the Device Settings.
The update, marked by build 61.1.A.1.149 brings, in addition to all the changes presented by Google such as Material You, privacy dashboard and updated widgets, the security patches of December 2021.
If, on the other hand, you own a Pixel or have installed an AOSP-based ROM, and you also want to get the old toggle back, know that it is possible to get it back again, with a simple ADB solution.
