Don't Wait If You Find Something You Like
Don't let the Galaxy Note 20 hold you back. If you find a phone that you like that fits into your budget, don't be afraid to commit. Most carriers allow you to upgrade after a year so you can always snag the Note 11 early next year if you wind up loving it.
Before you commit to waiting for the Note 11, make sure you go hands-on with alternatives. There are a bunch of solid options on the market right now.
Dig through all of these. You might find something you like well ahead of the Note 11's launch.
