When or why to clear Cache?

Cache storage is basically there to speed up the loading time of apps and overall system. It stores all the data that a user loads again and again. Be it thumbnails, some preferences or something else. It also extends to particular apps’ data. It holds stuff that any users accesses again and again from same place. This is why, none of this data holds any importance. It can be deleted and nothing is affected.

When the Galaxy S10/S10+ starts getting slower or the apps do not work normally, it is an indication that cache is now corrupted. It may seem very trivial but this happens very often. Moreover, if you apply an update like a security patch or a major OS update, the old cache can make new update not work properly. Sometimes, the Galaxy S10 may get slow after installing new update. In order to fix this, clear the cache storage.

Similarly, when apps are updated, the old cache may not work properly with new update. This results in lot of force closed errors. In order to fix all of these issues, we have to clear the cache partition.

How is cache stored in Galaxy S10 devices

In total, there are two main cache stores in these devices. The first one is system wide cache partition. It contains everything. We usually need to wipe it when a system update is installed and phone does not work normally after it. This is accessed from the stock recovery. We are assuming that most people run with stock recovery therefore, this guide only targets that.

Secondly, each app has a cache storage. It is accessible via each app’s settings menu. Normally, you can clear both the data and cache of these apps. However, some apps may only restrict it to cache option. Since it is the safest option, there is no harm in clearing it. Use this option when app does not work properly after an app update from Play Store.

How to clear an App’s cache

Use the steps below to clear cache storage of any particular app on Galaxy S10, Galaxy S10+ or Galaxy S10E. This is particularly useful when a certain app starts misbehaving. An app like Google Play Services may start consuming too much battery, present login issues, or show the App closed errors.

Cache memory stores all the repetitive information for an app to work. If this data gets corrupted, the overall performance or app itself may be degraded. Use the following steps to clear cache of both user-installed and stock apps on Galaxy S10 series devices.

  • Scroll down this list to find the app you’re looking for.
  • Tap on its icon.
  • In next screen, tap on “Storage”.
  • Now use the “Clear cache” option here.
  • This option will clear only the cache for that particular app.
  • If you want to completely reset data for that app, then use “Clear data” option too.
