edit: Never mind. Backed up a little and realized that though Microsoft Launcher had taken over my phone, it also had a sales pitchy kind of invitation to make it the default "and experience even better" whatever. So went into apps to make sure original launcher was still there (updated just a few days ago, too). Did a little basic research to make sure- yep. All I needed to do was uninstall Microsoft Launcher and the phone would default to my carefully curated Android. I went to the Play Store and looked up Microsoft Launcher, using the uninstall function there. Nice and clean, and now my phone is back the way I like it.
Only the mystery of how it got installed in the first place remains. Interestingly, MS website says that support for it ends Dec 2019. Hundreds of people begging to know how to get rid of it.
original query: I got up this morning and found Microsoft Launcher on my Samsung 7. No notice. I hate it. The Android system worked fine for me, and I had it set up the way I wanted. I have been trying to figure out how to get rid of the damn thing ever since and am baffled. I think I got the process figured out, but am not sure what to look for. First need to reset to previous launcher. I am assuming that in my app list that Google is the previous launcher. Can anyone confirm?
