Hello readers! In the particular post, I'll discuss one of the most common issue that android users were complaining for the past several years. As a matter of fact, this problem is not exclusive in Samsung devices but to all android platforms available in the market today. So, if the issue started right after the system updated, then it's quite obvious that it might be a corrupt files and data that your phone is using is causing it.
On the other hand, if you downloaded tons of apps before the update that would be another factor to consider that might triggering the problem wherein some of it might not be compatible to the new system and preventing the firmware to function normally that resulted the device to shuts down without apparent reason. But since we are not certain what the real problem is, all you need to do is troubleshoot your phone and consider all possibilities by doing some procedures until we can come up to the conclusion and get rid the issue. That being said, here are the procedures that we want you to do:
Step 1: Check if the battery is not swollen
Before anything else, it is imperative that you should check it first if the battery is swollen or not. Because if it is, then that would be the reason that your Galaxy S4 shuts down without apparent reason due to a faulty battery. To do so, just remove the back cover and the battery and place it in a flat surface or a table and flick it with your finger. If it spin, then obviously you have a swollen battery and you need to replace because it is already defective. However, if the didn't spin and the issue still happening proceed to the next step.
Step 2: Verify if the battery is faulty or totally-empty
Assuming that the battery is not faulty the next thing that you should do is to verify if the battery has enough power stored that could power up the hardware components. In other words, you have to charge your phone to a wall outlet to see if an empty battery is causing the issue. To begin with, you can simply connect the device to its charger and plug it in a wall outlet for several hours until its full. When the time elapse use again your phone and see if the problem still persist, if so, then jump over to the next method for further troubleshooting.
Step 3: Restart your S4 in Safe Mode
Restarting your phone is safe mode will eliminate the suspicion that a third-party app might causing the device to shuts down without a reason. Through this environment all downloaded applications will be disabled temporarily and the pre-installed ones will be left running in the system. So, if your phone is functioning normally while in this mode, then there should be an you need to uninstall to resolve the issue. Here's how to boot your phone in safe mode:
- Turn off your Galaxy S4 completely.
- Press and hold the Power button.
- Once the Samsung logo appears on the screen, release the Power button.
- As soon as you release the Power button, press the Volume Down button.
- Continue holding the Volume Down button until the phone has completed the reboot process.
- If you can read 'Safe Mode' at the bottom left corner of the screen, release the Volume Down button. Otherwise, repeat the process until you can boot the phone to Safe mode.
But while in this mode and your phone still shuts down, you can proceed to the next step for their might be a corrupted files and data causing it.
Step 4: Wipe the System Cache Partition
If the caches stored in the directory had become outdated or corrupted it could also trigger different types of performance-related issues like the one you have you have now, that is why it is important to clear the cache partition from time to time to avoid such issues like this to occur on your phone. Although there is no assurance if the problem will be fixed after the method but there were reports from others saying that after performing the method their device is already functioning normally. To do so, just simply these steps:
- Turn off your device.
- Press and hold the Volume Up, Home and Power buttons simultaneously.
- Release the Power button when the phone vibrates but continue to press and hold the Volume Up and Power buttons.
- When the Android System recovery screen appears, release the Volume Up and Home buttons.
- Using the Volume Down button highlight 'wipe cache partition.'
- Press the Power button to select it.
- The phone will automatically restart once the cache data are wiped out.
After you do so, observe closely if your phone still shuts down randomly, because if so, then your phone might have a serious firmware issue and the last option that you can do is to perform a reset. Through reset you are bringing the device back to its factory default and all your files and data saved on your phone will be deleted including your contacts, photos, music, videos and etc. So, before you follow the steps and do the reset, we suggest you to transfer first all of it your computer or SD card to be more easier for you to restore it once the issue is fixed. This is how you reset your Galaxy S4:
- Turn off your device completely.
- Press and hold the Volume Up, Home and Power buttons at the same time.
- Release the Power button when the phone vibrates but continue to press and hold the Volume Up and Home buttons.
- When the Android System recovery screen appears, release the Volume Down and Home buttons.
- Using the Volume Down button highlight 'wipe data/ factory reset.'
- Press the Power button to select it.
- Using the Volume Down button again highlight 'delete all user data.'
- Press the Power button to select it.
- Once the reset is complete, choose 'Reboot System now.'
- Press the Power button to restart the phone.
I hope this post helps.
