Is your Samsung phone storage increasing automatically even when you are not downloading anything? This is a frustrating but very common Samsung phone storage issue. Many users notice that free space keeps reducing daily without adding new apps, photos, or videos.
In this complete guide, you will learn why Samsung storage keeps increasing automatically and how to stop it permanently.
Why Samsung Phone Storage Keeps Increasing Automatically
The main reasons behind this issue are:
- App cache growing continuously
- Background app data
- System cache and logs
- App updates storing temporary files
- Leftover files from deleted apps
This problem is closely linked with the Samsung cache problem and often leads to the error Samsung storage full but nothing inside.
Step 1: Check Which Apps Are Increasing Storage
First, identify the apps causing the issue.
- Steps:
- Go to Settings > Apps
- Open apps like Chrome, Facebook, Instagram, YouTube
- Tap Storage
These apps silently grow cache and cause storage to increase automatically.
Step 2: Clear Cache to Stop Automatic Storage Increase
Clearing cache is the most effective solution.
How to do it:
- Settings > Apps
- Select the app
- Storage > Clear Cache
This step helps free up Samsung storage and stops hidden data growth.
System cache grows in the background and users cannot see it.
Steps:
- Power off phone
- Press Volume Up + Power
- Select Wipe Cache Partition
- Restart phone
This fixes many cases where Samsung phone storage keeps increasing automatically.
Step 4: Check for Hidden Files and App Leftovers
Sometimes deleted apps leave residual files.
- Open My Files
- Go to Internal Storage
- Check Large files
- Delete unnecessary APKs, logs, and temp files
If you don’t do this, storage may keep increasing even after app removal.
Step 5: Use Device Care for Automatic Control
Samsung provides a built-in solution.
- Settings > Device Care
- Storage > Clean Now
- Enable automatic cleaning
This prevents recurring Samsung phone storage issues.
