You may find that your running out of space on your phone as time goes on.
Despite the fact that you haven’t downloaded anything in ages!
The secret to this problem is your System Files.
I found my Pixel 3a had 21GB of System Files
Goto: Settings > Storage > Apps
Then proceed to sort them by size before going through the list and clicking “Clear cache” on every app.
This is a quick and easy way to clear up space on your Android phone.
