Galaxy-S4-Android-Free-Memory-Clear-RAM

One of Samsung’s additions to Android as part of TouchWiz is their own Task Manager, which features the handy option to free up RAM. RAM (Random Access Memory) is essentially how much space you have in your computer to run applications. The more RAM you have, the faster programs will run, and the more you will be able to run. Often applications can remain in the RAM even if closed – although the Galaxy S4 automatically shuts these down when RAM gets low, it can still be worth closing them yourself.

To free up RAM on your Galaxy S4:

  1. Press and hold the Home button beneath your screen.
  2. From the task manager, select the bottom left icon which opens the Task Manager.
  3. Select the RAM tab at the top.
  4. Now it will display the amount of used RAM and total RAM – the used RAM is the amount to the left of the /.
  5. To free up RAM, select Clear Memory at the bottom.
  6. Restart your phone and check if your issue is resolved.

Galaxy-S4-Android-Free-Memory-Clear-Cache-Data

As with most electronic devices, your smartphone or tablet stores temporary files to make it quicker to relaunch applications. Unfortunately these cached files do not clear themselves and build up on the phone. E.g. using Twitter several times a day on our Galaxy S4 for a month resulted in nearly 250MB worth of cached data. Cached data varies according to the app but we found the biggest culprits to be browsers, social networks and music streaming services.

Here’s how to clear cached application data on your Galaxy S4:

  1. From the homescreen, press Menu and then select Settings.
  2. Choose the More tab and then select Application Manager.
  3. Scroll to the right until you are at the ALL view.
  4. Press Menu and then select Sort by size <– this will now rearrange the list of your apps according to the amount of data they use.
  5. Select the app that uses the most data and then tap Clear Cache.
  6. Restart your phone and check if your issue is resolved.

You can also select the Clear Data button as we’ll cover below:

Galaxy-S4-Android-Free-Memory-Clear-Cache-Data

The process to clear an application’s data on your phone is similar to clearing the cache but which should you use? Whereas the cache is temporary files, the data is more permanent data such as accounts, settings, notifications, history, etc. If you choose to clear the data, you may lose your accounts etc and will need to readd them (exact loss – if any – varies according to the app).

Here’s how to clear an application’s data on your Galaxy S4:

  1. From the homescreen, press Menu and then select Settings.
  2. Choose the More tab and then select Application Manager.
  3. Scroll to the right until you are at the ALL view.
  4. Press Menu and then select Sort by size <– this will now rearrange the list of your apps according to the amount of data they use.
  5. Select the app that uses the most data and then tap Clear Data. <– do this for as many or as few apps as you wish.
  6. Restart your phone and check if your issue is resolved.

Galaxy-S4-Android-Free-Memory-Unused-Apps

A lot of people download apps and rarely use them – the freedom of Android means these apps can continue running in the background even if you haven’t used them in weeks. We would recommend uninstalling unused apps, to free up a range of resources (some unused apps use very little if any resources). To uninstall apps on your Galaxy S4 smartphone, visit our Galaxy S4 Uninstall Apps guide.

Galaxy-S4-Android-Free-Memory-Software-Update

Every so often your manufacturer or network will release a software update but many people don’t update their phone software. Updating the software is really easy and usually comes with bug fixes that may fix your problem.

To check if there are any updates for your phone, go to:

  1. Press Menu and select Settings
  2. Tap on the More tab (right on the four tabs) and scroll down to About Device.
  3. Select Software Update and then Update.
  4. If you’re connected to WiFi, it’ll check for an update. If on your mobile network, it’ll ask you whether you want to use mobile data to check for and download the update (updates can be up to 800MB so be careful if you have a data limit in your allowance.
  5. It will either say “The latest updates have been installed” or prompt you to download the update <– if you have updates available, download and install them and follow the on-screen instructions.
  6. Restart your phone and check if your issue is resolved - If your problem still isn’t fixed, you can try the last resort we have listed below.
