Problem 1: Galaxy S6 won’t install Android Nougat update

Hello. So glad I found this site. My phone prompts me to update, I believe, to Nougat, and it runs the whole thing, and restarts and all that. But after a few minutes it asks again. It doesn’t seem to actually, successfully be installing the update. I’m doing it for the fifth time now, just in case the update comes in several parts, but this is weird, and I don’t want to constantly have to be doing/delaying updates. — Aidan R MacGregor

Solution: Hi Aidan. There can be a number of reasons why this is happening in your device. These reasons can vary from a simple storage space issue, app problem, to a software bug.

Since we don’t know anything about your device’s history, we suggest that you do the three basic things common to all possible approaches in fixing this problem.

Create a backup

First, you want to ensure that you back your files up. This is an important step especially if you have lots of unsaved photos and videos. We suggest that you create a backup using Samsung Smart Switch app. If you don’t have much stuff to back up, you can also use Samsung Cloud which you can access under your phone’s Settings menu.

Wipe the cache partition

Once you’ve backed your files up, you can then try to wipe the cache partition of the phone to see if it will help in fixing the problem. All downloaded APKs or sets of installer files are saved in the cache partition. Sometimes, this cache can get corrupted and can lead to problems like failure to install app and/or system updates. To fix the problem, you want to refresh the cache partition by doing the following steps:

  1. Turn off the device.
  2. Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  3. When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  4. When the Android System Recovery screen appears, release the Volume Up and Home keys.
  5. Press the Volume Down key to highlight wipe cache partition.
  6. Press the Power key to select.
  7. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  8. Press the Power key to restart the device.

Factory reset the device

Factory reset should be your last resort if wiping the cache partition won’t work. This will allow you to:

  1. empty the phone’s internal storage device to ensure ample space for the new update and,
  2. return all software settings back to their defaults.

The steps below MAY also unroot the device if you have it rooted before. Keep in mind though that some root software may be able to stay after a factory reset.

  1. Turn off your Samsung Galaxy S6 Edge.
  2. Press and hold the Volume Up, Home and Power keys together.
  3. When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  4. Wait until the Android Recovery Screen appears after about 30 seconds.
  5. Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  6. Press the Vol Down button again until the option Yes — delete all user data is highlighted and then press the Power key to select it.
  7. After the reset is complete, highlight Reboot system now and hit the Power key to restart the phone.

Contact your carrier

We expect that wiping the cache partition or factory reset will fix the problem. However, if the issue remains, you should talk to your carrier and report the issue. They may be aware of it and can provide a workaround. Assuming you’re having a problem installing a carrier firmware, they should either advise you on what to do or simply replace the phone.

Problem 2: Galaxy S6 edge keeps freezing, slow performance issue

After updating to the latest system software on my Samsung Galaxy S6 edge +, it keeps freezing and hanging up especially when I play a video or use video related apps such as Facebook and WhatsApp. It takes a while for me to have control over the phone which was not the case earlier when I updated to the Nougat 7.0, about two months ago. The problem started after the recent update I made some two weeks ago. Its getting worse day after day even though I have done a factory reset thinking it might solve the problem. I have also wiped the cache partition you suggested in your tutorial but still the problem exists. Please help me out. — Tony Baffoe Bonnie

Solution: Hi Tony. Freezing or slow performance issues can sometimes be caused by poorly-coded or incompatible apps  so the first thing that we want you to do, since you’ve already tried wiping the cache and factory reset, is to observe the phone in safe mode. This will let you know if the problem is being caused by a third party app or not. While in safe mode, all third party apps will be blocked so if the phone works normally, you can bet one of your apps is to blame.

To boot your S6 to safe mode, follow these steps:

  1. Press and hold the Volume Down and Power keys for 20 to 30 seconds.
  2. Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
  3. Your phone should continue booting up and you will be prompted to unlock your phone as usual.
  4. You will know if the phone successfully booted in safe mode if the text “Safe mode” is displayed at the lower-left corner of the screen.
  5. Use the phone for 24 hours while it’s in this mode.

Remember, if your phone works normally, that’s a confirmation that there’s a bad third party app in the system. To fix the problem, you must identify the culprit. Unfortunately, identifying a problematic app can be a tedious process, especially if you have hundreds installed. You should uninstall apps one by one and observe the phone in between uninstall. Once you noticed that the phone works normally after you’ve removed an app, then you must have probably removed the cause.

Problem 3: Galaxy S6 creating a backup when power button is broken

Enough force on my Galaxy S6 inside its OtterBox bent it and it was still fully functional for 15 minutes after the incident that bent it. It did not crack the screen. I did not realize that there was damage to the frame and the phone did run all the way out of power and when I did charge it fully I realized that the power button will no longer work and the forced restart does not work. I have already checked my Google photos and some very important things are not backed up and I am trying anything to keep from having to file an insurance claim and give up on the data I don’t want to lose. If the volume and power buttons both do not work and you can tell that the frame is bent away so they are probably disconnected from where they should be but your home button still works, is there anything that can be done? Also when prompted by your question what Android version was I operating on, I have no idea and guessed lollipop. — Justacy

Solution: Hi Justacy. The only way to initialize a powered off Galaxy S6 is by pressing the physical power button. If it’s broken, then you must have it fixed first. The good thing is, if the phone was working normally before it ran out of battery power, there’s high chance that it would continue to work fine after the power key can be replaced. If that’s the case, you’ll most likely be able to create a backup of your files after repair.

Problem 4: Galaxy S6 water damage issue, wet S6 won’t charge or turn on

I dropped my phone in the toilet while I was at school. For the first hour everything was working except for the power button. When I got home I immediately put my phone in rice. A couple of hours later, I put the charger on for 5 seconds to see if it worked but it just glitched so I took the charger out. Then I left it in the rice for about a day and a half when all the moisture was gone and stuck the charger back in, it showed the charging sign but it never charged. I want to know if there is anything I can do to fix or do I have to buy a complete new one. I hope not because I never got the chance back up everything. — Amber

Solution: Hi Amber. Unlike the Galaxy S7 and S8, your S6 does not enjoy water resistance protection so even if you submerge it in water for just a second, there’s a risk that your phone can get damaged. Ideally, you are supposed to immediately turn the phone off, take the phone apart, remove the battery, and dry the device. We understand that you can do these things in an S6 unless you open it yourself. The main reason why you want to remove the battery from a wet phone is to prevent shorting other components. That this was not done may be one of the reasons why your phone no longer turns on right now.

Just like what we tell other users above, you can only create a backup if your phone turns back on. In its current state, accessing the internal storage device is plain impossible so creating a backup is out of the question as well.

The best thing that you can do right now is to see if the device can still be fixed without the need for parts or motherboard replacement. Be sure to bring it to Samsung or to an independent service center that can fix wet devices. Once they’ve dried the phone properly, they should be able to tell if it can work properly or if it’s better to just have it replaced.
