How to clear the system cache for the Samsung Galaxy S4

I have tried this on my galaxy mega 6.3 but after trying to wipe partition cache it displays error!

I have tried this on my galaxy mega 6.3 but after trying to wipe partition cache it displays error!

can you post the error message ..

I am getting the same error message...after selecting wipe cache partition after a few seconds it seems like it is worrking, then the little android guy shows up, laying on his back with a caution symbol over his stomach, and Error! written above. That all it says, then it boots like normal.

I am having problems with unstable internet as well, usually after it automatically connects to my works wifi. I turn it off, then my mobile date is weak and goes in an out. I have done all the suggested tips about clearing the wifi log, taking the battery out and rebooting, putting it in safe mode and uninstalling almost all my apps, etc, etc. Still can't figure it out. I definitely want to avoid a factory reset if possible.

I would have thought that doing this by the inbuilt cache clearer would be easier: Go to Settings>More>Storage and scroll down and tap on Cached Data. Click OK on the pop-up confirming to clear ALL cached data and the all the phone's data is removed.

One caveat: the Samsung dependent cache is protected and will not allow it to be cleared, but this was only 12kb on my phone.

Clearing the cache as Scott mentioned above does not clear the same cache as performing it through Settings. For example, my S4 had about 370MB of cache as reported in Settings before and 362MB after clearing the cache as Scott mentions. It does not clear all of the cached data your apps have. Much less drastic cache clearing, it is only temporary data cached by the OS. As Scott mentioned, NO personal data is cleared.

It is probably caused by OK Google being available from all screens. Change the settings to make it available only from the Google screen.

Hey AndroidPIT readers,

If you have problems with your [Samsung Galaxy S4][1] and that the smartphone isn't working properly, a good solution to this is to wipe the system cache of the phone. You don't even need to do a hard reset. In fact, doing a system cache will NOT delete any of your personal info, but only the background and application cache. Cache is stored data on the phone which allows apps to load quicker, it's like the data is on standby until you need it again. Wiping it simply means that the app will have to reload the data.

Here's how it's done:

Turn off phone
Remove the battery and reinsert.
Hold down the Home and Volume Up keys
Press and hold the Power button while still holding the other keys.
As soon as you see the Samsung logo, release all keys/buttons.
Press on the Volume Down to scroll down to Wipe Cache Partition.
Press the Power button to select it.
Press the Volume down button to highlight "Yes" and press the Power Button to select it.
Wait for a few minutes for the phone to clear the data.
Then press the Power button to select reboot system now.
Wait for your phone to reboot.

There you go! Your system cache should be wipe and leave you with a much more fluid smartphone.

Did this work for you?

Hi Scott,
You mention the "Samsung Galaxy S4" but does
this also work for a "Samsung Galaxy S4 Mini"
Andy

Thanks it worked.

If you want to clean up the junk files , you need to completely delete them on the phone , the simple deletion can not delete data you unwanted on the phone premanently ,once you erase data on the phone no one can recovered them from phoen ,

If you really want to delete the phone data , i think you can try using android data erase tool to clean up android data thorough,you can wipe out the messages ,photos,contacts,videos,ect on the android phone ,

The effective way to clear the phone system is clean phone memory , what you need to do is delete and erase unwanted files from Samsung permanently

Worked on my HTC phone too?

I did this but when I scroll down to clear cache I get an error

As i know , more and more people like deleting Samsung data to clean the phone , but as we all know the deleted data can be restored from Samsung , this situation can not help us to clean Samsung , unless we can avoid the data be backed after deleted

It looks very simple, but can you make sure the deleted data won't be recovered on phone ?

Whether you need to clean up all junk files like system caches from Samsung devices, or you want to eraser data on Samsung permanently, you can run Samsung Eraser/Cleaner to do that, it is also support almost all Android phones and tablets.
