The exception to this rule are current Google Pixel phones (including the 4, 4XL, 4a, and 5 models), which come with unlimited High Quality photo and video storage. The next Pixel phones, like all other phones, will follow the June 1 rule though.
Also starting on June 1, 2021, are storage changes that will affect users of Google Workspace for Business, Google Workspace for Education, and Google Workspace for Nonprofits. Storage changes for these services can be found here: Changes to Google Workspace Storage Policy Timelines.
If you need more than 15GB of storage for your personal Google account, you can purchase more storage here. For those who don’t want to purchase more storage, depending on your phone, you may be able to go into your Google Photos settings and reduce your image quality to Express, and those photos will not count towards your storage limit. However, if you do this, be aware that the photos and videos will be saved in a lower resolution (3mp for photos and 480p for videos) and may not look as clear as you want them to be. To change your photo quality settings and check if you can change the quality to Express, follow the steps here.
