So I didn’t bother transferring my old text messages to my new phone. I will eventually do that but I haven’t so far because Android doesn’t have an easy to way to do that currently. It’s really curious actually. There are many third-party apps that can do it for you but as part of the native migration process, texts are included oddly.
I have to download and install such an app on my old phone, back up the texts to an archive, and then save the archive to my computer or the cloud. Then on my new phone, download the same app, then get access to the archive and then extract the old messages to the right place. It’s tedious but I kinda want my old messages.
