Many users have reported Samsung phone keeps restarting issues. In some cases, it happens when they are texting, taking a call, or using an app. In other cases, it happens when the phone is on charging or after an update.
Whatever the reason, it can be a major problem… After all, sudden and frequent restarts can cause data loss, disruption to workflow, and a major inconvenience, if nothing else!
Is your Samsung phone also acting weird and restarting on its own? Then, keep on reading. In this guide, we will explore what causes the Samsung smartphone to restart again and again. Next, we will look at different ways to solve the issue of random restarts for good!
Why Does My Samsung Phone Keep Restarting Again and Again?
It is only natural to think about what’s causing the random or frequent restart issues. In most cases, a Samsung phone keeps restarting due to hardware or software glitch. But, it can also occur due to incorrect settings or a really old battery.
Let’s take a look at each cause in detail to better understand why Samsung keeps rebooting:
Auto Optimisation is On
Samsung phones feature a built-in “Auto Optimisation” option. This is a handy feature that performs various optimizations in the background. This includes cleaning up memory, cache, and closing any background apps.
The Auto Optimisation feature can also restart the phone on its own when the phone is not in use. According to Samsung, this is done to keep the phone running optimally.
The Power Button is Stuck
An average person can spend anywhere from 3-4 hours on their phone. This frequent usage can also lead to a build-up of dust/debris in the power button.
Gradual build-up of dust and debris can cause the power button to get stuck and malfunction. In such a case, the phone can start to restart randomly as the foreign particles start to interfere with the phone’s connections.
Outdated Software And Apps
Another reason why your Samsung phone keeps rebooting is outdated apps and games. When the apps are not updated for a long time, they become incompatible with the phone’s OS.
Updates usually contain optimizations and fixes to keep apps running smoothly. So, when you use an outdated app, you are actually using it with unresolved bugs and other issues.
Also, not updating the phone’s software (operating system) can also cause frequent and random restarts. Samsung OS updates contain security fixes, new features, and bug fixes. This means using a phone with an outdated OS can cause errors, leading to restart issues.
Third-party Apps
Some third-party apps contain faulty code, which can disrupt the normal operations of a Samsung phone. This can cause the OS to crash or hang, leading to frequent restarts.
Also, some 3rd party apps are malicious in nature and may contain some code to restart the phone frequently. However, this usually happens when you install apps from an untrusted source.
Your Device is Running Low on Storage
Low storage is yet another reason why your Samsung phone randomly restarts! When your phone runs low on storage, it takes a toll on the functionality and can cause many system processes to stop working.
To fix this, the OS may attempt to restart the phone as it can free up some space. This usually happens if you have installed a lot of apps or have too much data on the phone. Especially, if you are not using an SD card and the phone’s default storage is limited, you can run low on storage.
Aging Battery
Just like your phone gets old, your battery can also age and deteriorate. An old battery can not deliver consistent power to the components of the phone.
So, when the phone experiences periods of no power, it can cause the phone to shut off or restart unexpectedly. The issue of aging battery usually happens after 2-3 years of consistent use.
If you bought a used/refurbished phone, there’s a good chance that aging battery is the reason why your Samsung galaxy keeps restarting.
Software Glitch
Glitches or conflicts within the phone’s OS, firmware, or system files can also cause frequent restarts. Sometimes, the OS updates introduce a bug or cause corrupted system files.
Other times, the installed apps on your Samsung phone can conflict with each other. It consume more system resources and eventually forces the OS to restart the phone.
Certain apps also run in the background for their functionality. But, if these apps contain a glitch or start to use too much resources, it can hang the device and lead to a restart.
Defective Motherboard
Although rare, a phone can also restart again and again due to hardware issues. It usually happens due to a defective motherboard.
Damaged capacitors and other components of the motherboard can cause problems in data processing. It also disrupts the power flow, leading to repeated restarts. In addition, moisture, physical damage, or manufacturing defects can also damage the motherboard and cause restarts.

To rule out this case, just take off your phone case and see if it solves the restart issue. If the issue is gone, it means you need a new phone case that doesn’t press too hard on the power button.
