For example, a phone advertised with 32 GB of storage may only offer 25-26 GB for user content like apps, games, and media. Over time, as this space fills up, you may encounter an “Insufficient storage space available” message when trying to install new apps or save files.

Once the app is installed it will take care of the rest. Using the app is also pretty easy. It has a storage analyzer that shows how your internal memory is being utilized at the moment. You can use the app to directly delete unwanted junk with just a couple of taps. A dedicated Quick Clean button allows you to clear junk files instantly. It also has a RAM booster that clears apps running in the background and frees up RAM which makes the device faster.
