For the most part, Android devices have a great deal of storage, giving users the ability to store all the pictures, music, videos and apps they need without fear of losing their data. However, especially for those who use their Android devices for business, sometimes it comes to a point where you need more storage. There’s a great way to fix this issue.
Instead of deleting the cache for each individual app, users with Jelly Bean 4.2 and up can clear all stored data at once.
Go to Settings > Cached Data. From there, you’ll see the option to Clear All. This will free up unused space and let you continue using your phone as usual.
