FAQ: Frequently asked questions about clearing the cache

❓ Will clearing the cache delete my photos or contacts?

No, caches are temporary application files. Your personal data (photos, videos, contacts, messages) are stored in other memory sections and are not affected when clearing the cache. However, some applications (for example, instant messengers) can delete downloaded media files from their cache.

❓ Why do applications take longer to load after clearing the cache?

This is normal: applications need to re-create temporary files (thumbnails, data for fast loading, etc.). After 1-2 starts, the speed will be restored. If the brakes remain, the problem is not in the cache, but in the application or system itself.

❓ Is it possible to clear the cache of system applications?

It is better not to do this manually. System applications (for example com.samsung.android.app.launcher) may become unstable after clearing the cache. Use only standard tools for them (Device care or Recovery Mode).

Depends on the use of the phone:

  • 📱 Average user: 500 MB - 1.5 GB
