Samsung Galaxy S7 Edge stuck on logo & keeps rebooting after an update

• How to troubleshoot a #Samsung #Galaxy S7 Edge (#S7Edge) that can’t successfully boot up as it gets stuck on the logo. The problem started after a firmware update, which suggests the new system is the culprit.
• Learn how to fix an S7 Edge that randomly restarts on its own without apparent reason. The issue also started after an update but it might just be a simple switch issue.

There are two most common firmware-related issues reported by Samsung Galaxy S7 Edge owners; being stuck on the logo during boot up and random reboots regardless of what the user is doing. They often occur after a firmware update that’s why many are worried that the new firmware brings problems instead of fixes.

In this post, I addressed these issues once again as we’ve received quite a lot of complaints that are related to them. Continue reading to understand these problems and to learn how to troubleshoot them. I included troubleshooting procedures you can use to fix them, although there’s no guarantee.

An update caused Galaxy S7 Edge to get stuck while booting up

Problem: I have the Galaxy S7 Edge, which is just 5 months old and there have already been a few updates I installed since I bought it and all of them were successful. The last update, however, seems to have messed it up pretty badly because the phone just won’t boot up to the home screen. Either it gets stuck on the logo (I already tried leaving it on that screen for 2 hours) or the black screen after that. This problem started after the update was installed and the phone rebooted on its own. I am sorry to say but I really don’t know if the update was successful or not. Can you guys help me out, please? — Ray

Troubleshooting: Updates may require a reboot to be properly implemented after the installation and this problem of yours seems to have been caused by corrupt caches or data. We’ve already seen a lot of issues like this before wherein the phone cannot continue booting up and gets stuck somewhere during reboots. There is one procedure that is very effective in fixing this issue and that’s what I want you to do first.

Step 1: Wipe the cache partition of your Galaxy S7 Edge to delete all caches

System and app caches may be corrupted during an update while others may be incompatible with the new system that’s when the new firmware uses them, conflicts occur which may result in problems like this or greatly affects the overall performance of your device. I don’t know if you’ve already heard this but it’s actually a good practice to clear the caches once in a while to make sure everything is working smoothly. After all, caches can be deleted and replaced by the system without adverse effects to your phone and this is how you do it:

1. Turn off your Samsung Galaxy S7 Edge.
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.

I think wiping the cache partition can fix this issue but in case it remains after that, then you a reset might be necessary. The problem is you will lose all data and files saved in your phone’s internal storage and that’s not really practical especially if you have some important files you can’t afford to lose. In this case, I suggest you do the next step first before doing the reset.

Step 2: Try booting your Galaxy S7 Edge in safe mode

Some third-party apps may become incompatible with the new system and there are times when they cause issues like this which prevents the phone from properly booting up. So, to rule out the possibility that third-party apps have something to do with it and to see if you can still backup your data and files, boot your device in safe mode first:

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.

If your phone has successfully booted up in safe mode, there’s a big chance you can fix the problem without doing the reset provided that its performance remains the same. I also suggest that you grab this opportunity to backup your important data and files and after that, try booting your device normally without doing anything yet.

I’ve seen cases wherein the phone just needed to run in diagnostic mode wherein only pre-installed apps and services are running. Once done, it may run properly when booted up in normal mode that’s why I want you to try that as it might save you from all the hassles of backing up your data.

After you’ve backed up your files and that the problem still remains (i.e. cannot boot up successfully in normal mode) or if the phone can’t boot up in safe mode, then you have no other option but to do the next step.

Step 3: Boot your Galaxy S7 Edge in recovery mode again and perform the master reset

This procedure will bring your phone back to its factory defaults while leaving the new firmware running. It also reformats both the cache partition and the data partition, which contains all your preferences, personal information, apps, etc. It might be your last resort but there’s no guarantee the problem will be fixed especially if the update process wasn’t successful in the first place. Here’s how you do it…

1. Turn off your Samsung Galaxy S7 Edge.
2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.

NOTE: It doesn’t matter how long you press and hold the Home and Volume Up keys, it won’t affect the phone but by the time you press and hold the Power key, that’s when the phone starts to respond.

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.

NOTE: The “Installing system update” message may show on the screen for several seconds before displaying the Android system recovery menu. This is just the first phase of the entire process.

5. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
6. Once highlighted, you may press the Power key to select it.
7. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
9. The phone will now reboot longer than usual.

It is effective in dealing with problems like this but if the issue remains after the reset, then you have no options but to send it in for checkup as the firmware may need to be reinstalled.

Galaxy S7 Edge won’t boot up successfully; it turns on but restarts after a few seconds

Problem: Hey guys! Let me tell you my problem. My phone is the Galaxy S7 Edge that my wife gave me on my birthday and I’ve been using this for 3 months now. I love it because it’s fast not to mention its great design. One day, there was some kind of an update that downloaded on its own but the phone continued working a few days after that so I’m a bit hesitant to believe it was the update the ruined it but I’m also open to the idea. The this is the device powers on when the Power key is pressed but a few seconds later, it turns off. I will then press the power key again and the same thing happens. Did the update ruined my phone? Can the problem be fixed? — Dawn

Troubleshooting: There are several factors that may lead to this problem and apparently, we don’t know what happened to your phone and why it’s doing this. Therefore, we need to troubleshoot it to learn what the issue really is so that can be able to formulate a solution that may fix it. That being said, there are things you have to do and here they are…

Step 1: Verify that the Power key isn’t stuck or damaged

If the Power switch is stuck, the device will keep turning on and off until the battery is all drained up. Most of the users who encountered this problem thought it’s a hardware issue and went straight to the tech to get the thing sorted out. Opportunistic technicians, on the other hand, may say the problem is serious; open up the phone, do a little cleaning, put everything back again and turn the phone back on.

My point is you need to do some troubleshooting because you don’t know if the problem is serious or not. You may have to pay a lot for a minor problem such as stuck power switch.

If the device keeps turning off after you’ve turned it on, then try pressing the Power key multiple times. This simple procedure can easily fix stuck power switches. If you have third-party cases, remove them to rule out the possibility that the accessory is causing this issue.

If the problem persists, however, there’s a possibility the switch is damaged and the circuit is left closed that’s why the phone can’t continue being on. At this point, however, we really can’t be sure if it’s the switch that has some issues or it’s the hardware. So, continue troubleshooting to the next step.

Step 2: Boot your phone in safe mode to see if it can stay in that state

Let’s try to see if your apps have something to do with the problem. Booting it in safe mode will temporarily disable all third-party apps so if the problem is caused by one or some of them, the device may be able to boot up successfully in that state.

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: Boot your Galaxy S7 Edge in recovery mode

Assuming the phone still turns off or restarts on its own even in safe mode, then it’s time to try to boot it into the Android system recovery. You don’t have to do anything after you’ve booted up in that state except wait for the phone to reboot because if that’s the case, then it’s a hardware issue and you need to have the device checked by a technician, otherwise, a reset might be able to fix it.

1. Turn off your Samsung Galaxy S7 Edge.
2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.

NOTE: It doesn’t matter how long you press and hold the Home and Volume Up keys, it won’t affect the phone but by the time you press and hold the Power key, that’s when the phone starts to respond.

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.

NOTE: The “Installing system update” message may show on the screen for several seconds before displaying the Android system recovery menu. This is just the first phase of the entire process.

I hope this helps.
