LG Stylo 4
If you're looking for a Galaxy Note 9 but you're on a budget, consider the LG Stylo 4. Announced and released in July of 2018, this phone has a big 6.2-inch display and a stylus. It's LG's vision of a cheaper Galaxy Note.
You'll get a powerful 8-core Qualcomm Snapdragon processor with 3GB of RAM, a 6.2-inch 1080p HD display with an 18:9 aspect ratio and small bezels. Then, it takes good photos with a decent 13MP camera, 5MP on the front, Android 8.1 Oreo and a few other goodies. Yes, it'll get Android Pie in 2019, too.
Additionally, there's a fingerprint scanner, USB Type-C, a 3.5mm headphone jack, fast software, and multiple apps designed to take advantage of the Stylus. And finally, it has a 3,300 mAh battery which is about average, if not a little small considering the screen size.
