Most people have nearly everything they need on their smartphones. From email to games, work stuff and family stuff, it's tough to imagine being without your mobile. But if you've got tons of stuff, or if you're running less than a flagship model, then you might find that you're running out of space. That dreaded “low storage” message means that you need to go through your device and delete things that are important to you. But what if we told you that you might not need to get rid of anything or start backing up files elsewhere? Replace a few of those big storage apps with a suitable low storage alternative, and you might find that you have all the space you need.
