Problem 1: Galaxy S7 edge not turning back on

My Galaxy S7 edge started showing black & green vertical striped & shadows. Then once the battery ran out it & charged it it now only flickers a green screen when I try to switch it on. I tried pressing & holding power button but nothing else comes up. — Axelle

Solution: Hi Axelle. Does your phone still shows signs that it’s booting up? Some of the indicators of still booting Galaxy phone includes:

  • a lit or flashing LED light
  • sound notifications for incoming SMS or app alerts
  • vibration after restart

If your phone still shows any one of these items, the most likely problem is screen malfunction. Consider starting the phone to alternate boot modes and see if you can turn it on. Only then can you do follow up troubleshooting and may be fix the issue at your level. Below are the steps on what to do:

Boot in Recovery mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 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. You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to do it.

Boot in safe mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Remember, if your phone remains unresponsive or won’t restart to any boot mode at all, have it repaired or replaced.

Problem 2: Galaxy S7 stopped receiving text notifications

Recently my S7 has stopped receiving text notifications. I went through one of your steps and put it in safe mode and tried and it worked. So I know it’s an app that’s interfering. How do I found out which app it is? Do I have to delete all my apps one by one and test after each, or is there an easier way? — Samantha

Solution: Hi Samantha. If you can remember what app you installed before noticing the problem, we suggest that you start with that one. Otherwise, yes, you want  to uninstall third party apps one by one, making sure to test how SMS notifications works after each uninstall.

Problem 3: Can’t transfer files in and from Galaxy S7 to SD card

So i just bought a 64GB S7. Under storage it has internal (total space of 63.57GB), 5.49GB available, 719MB apps, 9.28 cached. Under that phone storage (41.09GB total) 34.66GB available, 1.16MB apps, 11.5MB pics/vid, 160KB audio, 32KB downloads, 2.75MB cached data, misc 5.14MB. Yet, i have insufficient space to download any apps. i can’t get anything on this phone.

All the apps i have work fine but i can’t put anything else on it.. it does not give me an option to save any of the already installed apps to all that internal storage. nor can i uninstall anything that comes on the phone.. i can barely use it. if it doesn’t say that there is insufficient space it gives me an error code, ie: -506, 963.. don’t remember the others. can’t get past the insufficient storage to find them. when i have my sd card in it, it reads it just fine, but does not give me an option to move anything to it. — Chrystal

Solution: Hi Chrystal. There may be a third party app preventing the system from moving files and apps around so the first troubleshooting step that you want to do is boot the phone to safe mode and see how it goes. Safe mode blocks third party apps and services so if file and app transfer works, you can bet an app is at fault. Here are the steps on how to boot your phone to safe mode:

  1. Press and hold the Power button.
  2. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  3. Continue holding the button until the phone finishes rebooting.
  4. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  5. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

If the same problem occurs after booting to safe mode, refresh everything by wiping the phone via factory reset and reformatting the SD card. Make sure to create backup of your files in both internal phone storage and SD card first before a factory reset. If you have a computer, you can download and install Smart Switch to it to allow you to create a backup easily.

Below are the steps on how to factory reset your S7:

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

Problem 3: Galaxy S7 apps stop working after an update

Hi guys. I have a problem with my Galaxy S7 phone. First of all, this device has been with me for more than 3 months already. The problems started last week, guess I used Bluetooth and GPS at the same time. From that time I received the first message “Music has stopped” and after some days the keyboard disappeared when I have to type something.

Then I have decided to update the system while there are some system updates and I wished it would solve that annoying bug. But after that update it became much more worster. From now on, it popped up several messages like “System process can’t processing”, Music keeps stopping, and some more. I recognised that I should not use wifi even in safe mode because then it starts a booting and crashing looping when try to use the keyboard because it doesn’t appear. In addition, it starts and crash randomly after turning the display off. Extremely annoying when you are on a long travel and you have no computer to safe your data and you are need it everyday to call, navigate etc.

Also I tried to update all apps especially the music app from Samsung but still facing this issue. Is there something I can do to fix this problem? Please help me. — Georg

Solution: Hi Georg. The only effective solutions for post-update issues are cache partition wipe and factory reset. If you haven’t tried them yet, make sure that you do. We’ve already discussed the steps on how to factory reset an S7 above, be sure to refer to the steps above.

To wipe the cache partition, do the following:

  1. Turn off your Samsung Galaxy S7.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 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 doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

Problem 4: Galaxy S7 edge keeps crashing and becoming unresponsive

Hey there. So basically I bought my S7 edge off some guy. It was in really good condition and it worked perfectly fine until it started having the “black screen of death” and constantly crashing. So I sent it in to Samsung and they replaced the battery component and the LCD screen. I got it back yesterday and fell asleep with it being fine, just to wake up to it crashed and unresponsive. Once I got it back on it was fine but my phone when connected to charger at 100% keeps connecting and disconnecting and crashing. Please help, I’ve done a hard reset and other. — Olger

Solution: Hi Olger. An issue like yours can be quite complicated because there’s a number of factors that must be considered. Random reboot issue, when paired with charging problems, can be a bad sign. They can be indicators of an on-going motherboard issue, which means that one or more components may not be working properly at this time.

In some cases, random reboot is caused by failure of the operating to read battery levels correctly. To fix that, you need to try to recalibrate the battery. Here’s how:

  1. Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
  2. Turn the phone on again and let it turn itself off.
  3. Charge the phone without turning it back on.
  4. Wait until the battery says it fully charged to 100%
  5. Unplug the charger and turn the phone on.
  6. If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.
  7. Unplug the charger the turn the phone on again.
  8. Use the phone until you drain the battery down to 0.
  9. Repeat the cycle once.

If it appears that the problem won’t go away after performing a battery recalibration, you may have to do a follow up factory reset. This will ensure that you eliminate possible software-related cause. Factory reset reverts all software settings back to defaults so everything will be back to their known, working state. If the issue continues despite having performed a factory reset, you should consider a phone replacement. We don’t usually recommend repair in this case since random reboot issue is usually caused by a complicated failure of components. Unless a technician can diagnose the issue 100% and replace malfunctioning components, there’s no guarantee that the issue will return after some time.

Problem 5: Galaxy S7 began downloading cache files by itself after an update

I have a Galaxy S7 edge and recently after an update it started downloading cache files in my Gallery of messenger stickers and emojis as well as pics from a game. In one day I literally end up with between 1,000 to 1,500 separately named folders in my phone all labeled cache. — S. Garcia

Solution: Hi S. Garcia. What happens when you delete the files? Do they become re-downloaded? Do the folders come back after deleting them? If yes, then wipe the cache partition first, and do factory reset if the issue won’t stop.

It’s possible that a poorly coded or even bad app is responsible for this as well. If you are positive that these folders should not be there in the first place (keep in mind that legit and good apps create their own cache all the time), go over your list of apps and weed out possible problematic ones. After you do a factory reset, install apps individually and check if the folders come back. This procedure will take time but will greatly help you in identifying the culprit.

Problem 6: Galaxy S7 fast charging feature won’t work

Hello team support! I am currently facing a problem with my Fast Charge option from the Samsung Galaxy S7. Before I start explaining the problem I want to mention that I am using the original charger (that means original USB cable and the one that goes in the wall).

Until yesterday, the fast charging was working perfectly fine (I bought the phone 1 year ago and never had a problem with it). Today when I tried to charge it, the notification usually says “Fast charging” changed into “Charging by cable.” Now the phone is charging very, very slow.

What I tried to do :

  • turn on/off the fast charging for the settings
  • make sure the fast charging is on
  • clear all cache data (using the menu with volume up + home + power on while the phone is turned off)
  • tried to use another original charger from another Samsung device (ex:Samsung Galaxy J3)
  • clear usb port — Leonte

Solution: Hi Leonte. Except factory reset, you’ve already done everything that any user must do to try and fix the problem. Should the issue stay after performing a factory reset, that means that the charging port may no longer be working properly. Contact Samsung or the relevant party to have the phone repaired or replaced.

Problem 7: Galaxy S7 opens random apps by itself

My Samsung S7 has had many issues lately, but the one puzzling me the most is that it will open apps while I’m using others. For example I could be on a store (Kohl’s) app and then I will hit the left “button” at the bottom of my phone next to the home button to “close all” out when I’m finished, and it will show 3 or 4 random apps are open. These 3 or 4 random apps are sometimes apps I haven’t used in days, weeks or even months so I know that I didn’t open them. They just pop up while I’m on another app and I have to close them as part of the “close all” feature. I just went through my phone and deleted A TON of 3rd party apps and only kept the ones I really wanted, and have never had issues with. I also did a while phone cache clean out Where could this be coming from? — Katie

Solution: Hi Katie. You may haven’t get rid the problematic app even after uninstalling a lot of third party ones. Try to boot your phone to safe mode and observe the phone for a few days. If the problem won’t occur during this time, you can bet an app or service is the culprit.

Problem 8: Galaxy S7 edge screen stays black and won’t turn on

I was watching a video on You Tube and suddenly the screen of my Galaxy S7 edge gone white. After that it started flickering. I tried fix it by pressing the turn off button but nothing. I saw that lots of guys have the same problem and I want to know if it’s possible that Samsung is covering this kind of problem frow the warranty. I never dropped my phone or something like that, so will be not fair if the warranty is not covering this kind of problem. — Nasko

Solution: Hi Nasko. Like you, we don’t work for Samsung and we know nothing about any Samsung cover up of some kind. If track record is to speak, Samsung appears to be very proactive in dealing with known problems like the Galaxy S5 camera issue and Galaxy Note 7 fiasco. If you think a lot of people are experiencing the same problem as yours and you have data to back them up (we don’t), please contact Samsung.
