I had the most recent Microsoft launcher as my ui on my note 9. The past few days Google play apps would not download all the way. Sometimes they would just get stuck halfway through or at 99%. A few times it would be stuck at 100% but would not install. I tried all the Samsung fixes but it didn't help. So I finally did a clean install and used the Samsung ui and everything worked as in apps downloaded and installed. I reapplied MS launcher and it did the same thing with Google play apps. Did another clean install and now using the Samsung ui which I do not like. Anyone else had this problem and know. Fix. Thanks.
