Google Pixel 8a storage is full or the device cannot install updates

A Pixel 8a has 128 GB or 256 GB of storage and no card slot, so a full phone cannot be fixed by adding a card. Google's help page for freeing space has a plain route: open Settings, Storage, then Free up space, where the phone lists items it can remove, such as backed-up photos and videos, large files and rarely used apps. Turning on Smart Storage removes backed-up photos and videos automatically after a set time. The page also lets you choose a category and Select files, which suits downloads and screenshots. Photos and videos are usually the biggest users, so check that Google Photos has backed them up before you delete local copies.

System and cached data can also be large; clearing an app's cache frees space without deleting its data. Keep at least a gigabyte or two free so updates and the camera work. If the phone reports storage almost full though your files seem small, look at the System and Other categories, which include cached data and app data. Restarting the phone and clearing the Play Store's cache sometimes reduces these categories noticeably, and you can see each app's size in Settings, Apps, sorted by storage. Look at Files by Google or the Storage screen's Large files list, which sorts files by size and finds forgotten downloads and videos quickly.
