Galaxy S7 Edge stuck in Samsung logo and blurry blue screen

Problem: I was updating my system software on my Samsung S7 Edge and suddenly it is stuck.It just shows blurry blue screen with blurry android logo and saying installing system update. But there is no sign of update. The screen is not even clear it looks like the tv channel with lack of cable signal. I tried power button but nothing works. What should I do? Please respond asap.

Solution: Based it on the symptom that your phone is showing it seems like the issue is triggered due to an outdated files and data in the system. But since the problem started during the update process there is a big chance that this is just a software-related issue. One of the reasons that this is happening it is because the firmware might be crashing and that is why your phone is unable to boot up properly. However, no need to worry about this issue because it can be fixed through simple procedures without bringing your phone to the tech for repair. So, to isolate the problem we want you to follow these methods:

Step 1: Force restart your phone

This is a simulated battery-pull procedure in which, it closes all apps that is running in the background and refreshes the memory of your phone. If the issue is caused by a system glitch, then this method might fix it. To do so, just press and hold the Power and Volume Down keys together for 10 seconds and wait until it reboots. After doing it try to see if your phone screen still in blue color. If so, you can move to the next method.

Step 2: Try to boot it in Safe mode

This time, we will boot your phone in safe mode so that we can verify if one of the downloaded applications you installed is the main factor that the issue occurs. But take note, this is only an android environment wherein, all third-party apps will be disabled temporarily and the built-in apps will run in the system. So, if your phone screen function normally while in this mode, then obviously there’s a culprit that you need to find and uninstall. This is how to boot in safe mode:

  1. Press and hold the Power key.
  2. As soon as you can see the ‘Samsung Galaxy S7 Edge’ on the screen, release the Power key and immediately hold the Volume Down key.
  3. Continue holding the Volume Down button until the device finishes rebooting.
  4. You may release it when you can see ‘Safe mode’ in the bottom left corner of the screen.

Step 3: Wipe the System Cache partition

In this procedure, we have to delete all system caches so that the files your phone is using are new and could be loaded easily in the firmware. So, if corrupted caches caused the issue, then this method would surely fix it. Through this method, we are not just wiping the outdated caches in the system, but also verifying if there is no hardware components damaged that triggered the problem. If your device boots up normally it is a clear indicator that this is purely a software issue. This is how you delete the system caches:

  1. Turn off the phone.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 Edge shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished wiping the cache partition.Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

After you do so, observe closely if your phone still having a blue screen and unresponsive, because if it is, proceed to the last method.

Step 4: Master reset your phone

Remember, you can reset your phone if all procedures above is unable to resolve the issue. This will bring your device back to its default settings, meaning, all files and data stored in the internal storage of your phone will be deleted including your contacts, music, videos and apps. So, before you proceed to the steps we would like you to create first a backup so that you can restore all of it if the issue is fix. Here’s how:
