The Pixel Watch 2 might not work with older Android phones
Google recently showed off renders of its upcoming Pixel 8 smartphones. They also teased the upcoming launch of the Pixel Watch 2. If you skipped the original Pixel Watch and are holding out for the Pixel Watch 2, you might need a newer Android phone.
This is according to the landing page Google published in which at the bottom of the page, it states that users would require a phone that runs Android 9.0 or newer if they want to be able to pair the Pixel Watch 2 with their smartphone.
Prior to this, the Pixel Watch only required Android 8.0 or higher, so it looks like the Pixel Watch 2 is moving up an Android generation in terms of requirements. That being said, Android 9.0 was released in 2018, which is five years ago. There is a good chance that most users would have bought a new phone by then. Obviously there are probably still some users still holding on to their old phones, but we imagine that those are just a small set of users.
What this means is that if you bought an Android phone in the last 2-3 years, it’s pretty much guaranteed that the Pixel Watch 2 will be compatible with your device, but if you’re one of the few still using a super old Android phone, you might want to consider upgrading if you want to get the Pixel Watch 2.
