Method 1: Fix Samsung Galaxy S8 Lag through clearing cached data

This the most helpful method to fix lags and other performance related issues. Over time, the cache memory becomes so problematic that it lowers down the entire performance of the phone. Lags and sluggish behavior are very common things to observe.

Basically, the cache memory is linked to applications. Each time we open an application it accumulates some cache files. These are files generated to improve the response time of the application and sustain the user experience. However, these cache files expire after some time and remain in the cache memory. As we use our phone for a long time, it keeps on growing while it keeps impacting the performance and stability negatively.

Thus, it’s highly suggested clearing all the cached data once within two or three months. That collimates performance and stability. Social media apps create most of the cached data. Apps like Facebook, Instagram, Twitter, etc, accumulate oodles of cached files. Each of them is capable of gathering data in GBs within a few weeks. You better keep your eyes on these applications.

Therefore, you should clear the cached data on your Samsung Galaxy S8 to fix lags and freezing problems. Just follow the below instructions:

1. Open the Settings menu on your phone.
2. Tap on the ‘Device maintenance’ option.
3. Tap on ‘Storage’
4. Under this menu, tap on ‘CLEAN NOW’ button.

Within a few minutes, it will wipe all the clutter and junk files cause your phone run slow and sluggish. Most importantly, it will free a good amount of internal storage on your phone.

Remember, clearing the cache memory won’t remove any of your apps or files, instead, it removes the associated cached files. So, it might wipe the login details and app/game progress.

I’m pretty sure that clearing cache memory would fix most of the issues on your phone.

Method 2: Wipe cache partition on Samsung Galaxy S8 to improve performance

There’s one advance way to remove all the cached data. Android OS stores all the data into different partitions. So, the cache files are usually stored under the cache partition. No matter if that is, a system application/service or third-party application, the cache files are stored under this partition only.

The Android OS allows users to wipe this partition. That allows users to thoroughly wipe this partition, all cache files associated with the system and third-party apps would be removed.

So, if you found that method 1 doesn’t work then, you must try this method. To perform this action, we will get into the recovery mode and perform ‘Wipe Cache partition’.

Use the following instructions to perform this action on your phone.

1. Turn OFF your phone using the power button.
2. Now, boot into the recovery mode:

Sometimes the configuration itself stops the phone to function normally. The Android OS has plenty of customization and configurations. There are chances that recent changes you’ve applied causing the phone to lag and slow.

Since Samsung Galaxy S8 is powered by the Samsung Experience, a custom Android skin that takes customization and personalization to the next level. Unlike the stock Android OS, this skin has loads of custom apps and features. That helps to configure this phone more precisely.

We already know that Samsung loads tons of bloatware apps on their smartphone. In our recent tutorial associated with Galaxy Note 9, we figure that there were about 120+ bloatware apps (unwanted apps that remain unused whole time).

And we got 1.5 GB of free RAM after we disable these bloatware apps on Note 9. Of course, the result was impressive.

Now, it has been observed that third-party applications can affect the performance of the phone. You might have recently installed some applications (one or more could toxic) and they are causing problems. If you do suspect that issues may be linked with some applications, then probably you should try to disable or uninstall them.
