How to reboot a frozen Galaxy device
If your screen freezes or your device becomes unresponsive during use, you can force reboot by holding both the Side key and Volume down key simultaneously. If the issue persists after restarting the device, try following the steps below.
Note: Before you try the recommendations below, be sure to check if your device's software and related apps are updated to the latest version.
Free up Memory and Storage space
Your device may freeze or become unresponsive due to insufficient Memory and Storage space. If this is the case, try the following steps.

Step 1. Go to Settings, then select Device care.

If there is insufficient space on your device, you can clear the cache by optimizing your device. Optimization closes apps running in the background, manages abnormal battery usage, and scans for crashed apps and malware. Follow the steps below to optimize your device.
Step 1. Go to Settings and select Device care.
Step 2. Tap Optimize now.
Step 3. Once optimized, tap Done to finish
Check your device in Safe mode
Third-party apps may be the cause of your device becoming unresponsive. Since all third-party apps are disabled in Safe mode, you can check if a third-party app is the reason why your device keeps freezing. First, enable Safe mode to see if your phone becomes unresponsive. If your device does not freeze in Safe mode, it means a third-party app is the cause of the issues you are experiencing.
If your device has started becoming unresponsive recently, identify apps that you have downloaded lately and remove them in Safe mode. Follow the steps below.
You can switch from Safe mode to normal mode by following the steps below :
Step 1. Press and hold the Volume down key and the Side key simultaneously.
Step 2. Select Power off.

Step 3. Select Factory data reset.
Step 4. Tap Reset.
Step 5. Tap Delete all
Step 6. Enter your password and follow the on-screen instructions.
Note: Before performing a Factory data reset, make sure you have your device's data backed up. Data deleted during a Factory data reset cannot be restored.
