Android Phone Keeps Restarting by Itself? 8 Fixes That Work

 

Introduction

Does your Android phone keep restarting by itself without warning?

This problem can be extremely frustrating, especially when your device suddenly restarts while you're using an app, making a call, or browsing the internet. In some cases, the phone may enter a random reboot loop, restarting multiple times throughout the day.

Many Android users experience this issue at some point, and it can happen on different brands such as Samsung, Xiaomi, Oppo, Vivo, or other Android devices.

The good news is that most cases are not caused by serious hardware damage. Instead, random restarts are usually triggered by software glitches, problematic apps, overheating, or system update issues.

In this guide, we’ll explain why Android phones restart randomly and show you 8 effective ways to fix the problem.

Why Your Android Phone Keeps Restarting

Before trying the solutions, it helps to understand the common causes behind this issue.

Android devices rely on many background processes to keep the system running smoothly. If one of these processes fails or conflicts with another system component, the phone may restart automatically to recover.

Some common causes include:

• Software bugs or system glitches

• Problematic or incompatible apps

• Low storage space

• Overheating issues

• Outdated Android system

• Corrupted system cache

• Battery or hardware problems

Once you identify the possible cause, fixing the problem becomes much easier.

8 Ways to Fix Android Phone Restarting by Itself

Try the following solutions to stop your Android phone from restarting randomly.

1. Restart Your Phone Manually

It may sound simple, but performing a proper restart can resolve temporary system glitches.

When the phone runs continuously for a long time, background services may become unstable. Restarting refreshes the system processes.

Steps:

1. Press and hold the Power button

2. Tap Restart

3. Wait until the phone turns back on

After the restart, observe whether the random reboot issue continues.

2. Check for Problematic Apps

Some apps may cause system instability, especially if they are outdated or incompatible with your Android version.

If the problem started after installing a new app, that app might be the cause.

What you can do:

• Uninstall recently installed apps

• Update apps through Google Play Store

• Avoid installing apps from unknown sources

Apps that crash frequently may also affect system stability.

In some cases, unstable or outdated apps can cause system problems, including random restarts. If certain apps close unexpectedly on your device, you may also want to read our guide on Android apps keep crashing and how to fix the problem.

3. Free Up Storage Space

Low storage space can cause many Android system problems, including random restarts.

When the phone does not have enough storage, it cannot properly manage system files and temporary data.

To check storage:

1. Open Settings

2. Tap Storage

3. Delete unnecessary files or unused apps

Try to keep at least 2 GB of free storage for better system performance.

4. Check for Android System Updates

Outdated system software may contain bugs that cause random restarts.

Manufacturers release updates to fix stability issues and improve device performance.

Steps:

1. Open Settings

2. Tap System

3. Select Software Update

4. Install any available updates

Restart your phone after installing the update.

5. Remove the Phone Case if the Device Is Overheating

Overheating is another common reason why Android phones restart automatically.

When the phone becomes too hot, the system may reboot to protect internal components.

Try these steps:

• Remove the phone case temporarily

• Avoid using heavy apps for long periods

• Keep the phone away from direct sunlight

Let the device cool down and check if the issue improves.

6. Clear System Cache (Recovery Mode)

Corrupted system cache files may cause unexpected system behavior, including random restarts.

Clearing the cache partition can help remove these problematic files.

Steps may vary depending on the device, but generally:

1. Turn off your phone

2. Press and hold Power + Volume Up

3. Enter Recovery Mode

4. Select Wipe Cache Partition

This process will not delete your personal data.

7. Reset Network Settings

In some cases, unstable network connections may trigger system glitches that lead to restarts.

Resetting network settings can refresh your device’s connection configuration.

Steps:

1. Open Settings

2. Tap System

3. Select Reset Options

4. Tap Reset Wi-Fi, Mobile & Bluetooth

Network-related problems can also affect internet connectivity.

8. Perform a Factory Reset (Last Resort)

If none of the previous methods work, performing a factory reset may solve deeper system issues.

This will restore your phone to its original settings.

Important:

• Backup your photos and important files first.

Steps:

1. Open Settings

2. Tap System

3. Select Reset Options

4. Tap Erase All Data (Factory Reset)

After resetting, set up your phone again and check whether the restart problem is resolved.
