Don't Install If You Hate Dealing With Problems
If you don't have it in you to deal with bugs and performance issues, you should avoid the Galaxy Note 8 Android Pie beta.
This is a beta which means it's unfinished software. It can, and probably will, cause problems on your Galaxy Note 8.
Samsung will roll out updates to address some of the issues plaguing the current version of the beta but issues will linger all the way through the testing process.
If you depend on your Galaxy Note 8 to get you through work, school or just life in general and don't have time to deal with major problems, avoid the Galaxy Note 8 Pie beta.
At the very least you might want to wait for the next bug fix update to roll out.
