Android N's preview was released by Google on March 9, Wednesday and includes various new features including split-screen multi-tasking. That includes the ability to drag and drop text between multiple apps. It involves highlighting the next, holding it for a second, and then transferring it to the other application.
It seems that the function only works for content people are typing in the text box, according to The Verge. Thus, text could be transferred from an email to an instant messaging platform, but not from a web page.
Another issue is that the drag and drop feature does not seem to work with big blocks of texts. There are some other issues such as it not working with all mobile apps, but it is likely Google is tweaking the split-screen feature.
Android N will also allow users to respond to mobile alerts from the notification instead of the application.
Android's developer website notes that Android N is an Over The Air (OTA) update that sends the newest preview updates for N to mobile devices registered in the program. It is free and open to everyone with a supported mobile device linked to their Google account.
A big issue is whether the Alphabet subsidiary will bring Android N to Nexus 5, according to Android Police. There is a tag in the Nexus 5 repository that refers to an Android N Preview 1.
However, it is not clear if the new version of Android's OS is being developed for Nexus 5 based on the tag. That is because all devices that Android currently supports receive such tags, but it is not a guarantee that it will support those devices in the future.
For example, the Nexus 4 repo had a tag for Android M Preview 2 but the smartphone was never included in the M preview, and was never upgraded to Android Marshmallow.
After the phone received a Preview 1 tag for Marshmallow it was reported on the web that Nexus 4 owners would get Android 6.0. However, it did not happen.
Google could be ascertaining whether or not it will roll out Android N for Nexus 5. However, the preview tag for the new OS version does not increase or decrease the chance that will happen.
