We all know how frustrating can it be to experience software related issues on a high end smartphone such as the new Samsung Galaxy S9+. When so much power is provided is really hard to imagine how problems can occur in the first place. But, since we are discussing about an open source OS and about various third-party apps, updates and tweaks, dealing with malfunctions isn’t a strange thing after all. However, the most important thing is to know how to act quickly in order to address these problems manually, without having to take your handset back to service.

That’s why, during the guidelines from below we will try to describe and detail the most common troubleshooting solutions that can be applied on the Samsung Galaxy S9 Plus. These troubleshooting methods are the easiest that can be performed on the Android system and through which you can easily address general software related problems. So, we won’t be talking about hardware issues (such as faulty hardware components) or about complex procedures which are implying special skills. This tutorial is addressed to newbies and regular users who are trying to resolve problems on their own.

So, right from the start you need to know that the steps from this tutorial can help you solve issues such as boot loops, lags, hangs, screen freeze, battery drain, heating problems, signal strength issues, total blackouts and so on. Usually, these malfunctions are caused by buggy updates, by inappropriate tools, by malicious apps and even by malware. An unresponsive process can also be the reason why you cannot properly use your Galaxy S9+ and the same thing can happen if you apply tweaks without using dedicated tutorials – when we say tweaks we refer about gaining root access, flashing custom recovery images, removing bloatware, adding custom ROMs, MODs and kernels or overclocking / undervolting CPU frequencies.

Now, all the steps explained below are describing official procedures, supported by Samsung. Thus, the KNOX flag won’t get tripped and you won’t have to use any risky or complex tools. So, the warranty of your Galaxy S9+ won’t get void and you won’t lose access to built-in apps.

But, since some of the troubleshooting solutions mentioned here will imply in restoring your smartphone back to its factory state, it is important to backup your smartphone before starting the steps from this guide. Only in this way you can save what’s important for you: EFS folder, texts, images, videos, audio files, market apps, internet settings, IMEI / NVRAM data and basically everything that wasn’t there from day one. Don’t worry, the backup can be easily applied even when your device isn’t running as it used to – you can use built-in cloud storage apps, you can download backup and restore apps from Google Play or you can sync certain files with your Google account.

The last method that’s explained in this tutorial will fully restore your Galaxy S9 Plus back to its default state. In that case, even the tweaks that were recently applied will be revoked. In that respect, that particular troubleshooting process can be used if you want to unroot your Galaxy S9 Plus, if you want to reinstall the stock recovery, relock the bootloader and re-apply built-in apps and restrictions.

One last thing before starting the actual fixing steps: check (if possible) the power that’s left on your device. It’s important to charge your handset before resuming anything else – if the power is low your phone might get turned off right while you try to fix its Android system and in that case further issues can be experienced. So, as a general idea, plug in the charger if the power left is lower than 50%.

Of course, follow this step by step guide only if you own the Samsung Galaxy S9 Plus and try not to mess things up – stick to the explanations from below all the time.

How to Unbrick Samsung Galaxy S9 Plus

Access Safe Mode

Using safe mode is the first thing that should be done. In safe mode all third party apps and processes will be disabled by default. Thus, if the problems were caused by such apps, in safe mode everything will run smoothly – in that case you will know that you need to remove the recently installed apps. Shortly, in safe mode you can identify the problem, you can isolate it and you can even remove the malfunction. Therefore, before trying anything else, you need to learn how to enter and use Safe Mode on your Samsung Galaxy S9+.

Make a Hard Reset

If the issues cannot be fixed by using safe mode you need to make a hard reset for erasing everything that wasn’t there from day one. In that way, along with your personal data, info, accounts and files you will also manage to remove malware, inappropriate apps, malicious software and similar other packages that can cause different problems. Since the hard reset will delete everything it’s important to keep in mind that a backup shouldn’t be optional. Good; now, on the Galaxy S9 Plus you can easily complete the hard reset operation by using this dedicated step by step guide.

Clear app data cache

If after performing the hard reset you are still experiencing minor issues (such as a boot loop) you need to clear app data cache – in that way you will manage to remove even the hidden processes that weren’t cleared during the factory reset process. So, follow:

  1. On your Samsung Galaxy S9+ access the recovery mode menu.
  2. In recovery use Volume Rocker keys to scroll up and down and the Power key to select.
  3. After making the hard reset, choose ‘wipe cache partition’.
  4. Also, pick ‘advanced’ and select ‘wipe dalvik cache’.
  5. When done return to main menu of recovery and pick ‘reboot system now’.

Reinstall the stock Android firmware

If everything else fails, you must reinstall the stock Android firmware on your Samsung Galaxy S9 Plus. As already outlined above, this troubleshooting method will restore your device back to its factory state. So, now all the tweaks will be revoked and the factory restrictions reloaded.

Anyhow, this is also the best way in which you can address almost all the Android soft-related issues. And for doing so you will need access to a computer, where Odin will have to be installed (on that computer your phone’s drivers must be already flashed).

In a few words, you will have to run Odin on your PC, put your smartphone into download mode, connect your devices and initiate the flashing process from Odin – by clicking on the AP option you can load the firmware package and by pressing the Start button you can resume the actual installation process. In the end, your device should be running without any bugs or malfunctions – you can access the detailed update operation by using this tutorial.
