translated from Spanish: Three ways to free up space on your phone

The most efficient way to make your phone faster and more efficient is to free up some memory and the easiest way to do it is to eliminate excess things that we no longer use or that we no longer want to have.
1.- Delete all those photos, because they are already in the cloud
Unless you’ve set it up differently, your smartphone stores all your photos and images in the cloud, specifically in Google Photos. To verify that they are all there, just open the app and make sure you don’t miss any. You can then delete them from your phone’s gallery. This will free up a considerable amount of memory, especially thinking that most modern smartphones take high-resolution photos, resulting in more space per photo.
2.- Deletes the cache
On most smartphones you should manually clear the cache manually. Depending on how long you do it, you can get a couple of megabytes that will serve you for something else. Just go to your phone’s settings > storage > internal storage > delete cache.
3.- Uninstall old apps
I know it’s hard to convince yourself that you’re no longer using that app you installed two months ago and haven’t reopened, but you have to go into Zen mode and let go. Think that many of those apps can also be used on your computer, and that it may not be so bad. Also remember that you can delete files from those apps from your document browser.
