Galaxy S9 started its existence not too fast. Sales were slow because most people were not upgrading their phones to it. But now, moths after it’s release, the price has dropped to around $500 around the world. And with its Snapdragon 845, it is one of the fastest phones out there. The price is much more appealing and this feature set is often not available with other brands.
If you are in the market for a new electronic companion, you should look into Galaxy S9, it has an amazing camera (probably not the best in the world, but I think that it comes down to personal preference, and in my experience this camera is near perfect).
This topic was discussed on Dave Lee’s YouTube channel, I suggest you take a look at that video as a starting point for your research towards Samsung Galaxy S9.
