Troubleshooting Your Galaxy S9 Or S9+

This type of problem is quite technical so it might be wise to seek professional assistance from smartphone repairers. You might see the fix you want here, but in case the situation gets really bad, take it to those that repair for a living.

Below are the ways to rectify the randomly shutting down problem:

Check Your Samsung Galaxy S9 Or S9+ Battery

Like I said earlier, it could be a battery malfunction. What you have to do is to confirm if the problem continues even when the Galaxy S9 or S9+ is connected directly to a power source. If the problem continued then the issue might not be your battery. If the problem stopped, then your battery is the culprit. It might be faulty or may have lost its capacity to turn on the device.

To confirm if the battery is only drained, attempt to connect the charger to a stable power source for some minutes, then restart your Galaxy device. When you charge and discover that the issue is gone, replace your battery.

Simply buy one online or do it physically. But do not forget, even when you purchase one online, opening up your Galaxy phone will still require the help of a technician.

Test 3rd Party Applications

Most times, a faulty application can be the problem. “But how exactly can I test if a 3rd party app is faulty” you might ask, the answer is simple, it is by activating the Safe Mode.

Safe Mode will allow you to remove the faulty application to know if it is behind the freezing and shutting off randomly.

How Can I Get Into Safe Mode?

To enter Safe Mode, simply press and hold the Power button for some seconds. After that, release the Power button when “Samsung Galaxy S9 and S9+” is visible on the display, and click the Volume Down button. When that is done, hold on till the device reboots before releasing the Volume Down button as soon as “Safe Mode” can be seen on the display.
