Below are specific topics we’re bringing for you today:

Problem 1: Galaxy S7 keeps making sound notifications

I have had the phone for months with no issues. The last couple weeks though, the phone has started generating random notification sounds, but no notification messages/popups. The sounds are not constant and even change tone from a chime, tweet, and messaging beeps. I have not installed any new apps when this started either. I have turned off all notifications for each app both within the apps and from the phone settings. I have disabled notification reminders. Even with the notification, media, and system sounds turned off, it still makes these noises. Only when I also turn off the ringtones and make the phone completely silent do they stop. I have run AVG scan and manually deleted suspicious items from my phone. Still with no luck. Any information you may be able to provide would be useful. I have even started my phone in safe mode and cleared the cache partition. I’m at the point of resetting my entire phone and starting over. — Joseph

Solution: Hi Joseph. It’s hard to pinpoint what exactly is causing your concern by merely giving word descriptions of these sounds. We suggest that you go ahead with factory reset so you can observe if these uncalled for sounds continue or not. Make sure to observe the phone for at least 48 hours without installing any app or update. If the sounds won’t return in this state, that’s your proof that one of the installed apps is causing it. That may not necessarily mean that a malware has infected your device. We don’t think a malware developer will be dumb enough to try to sneak in their software in Android devices only to make users suspicious by constantly bugging them with unnecessary audio notifications.

Problem 2: Galaxy S7 became unresponsive and won’t turn off

My phone is in perfect condition, in its protective case, with its protective screen. It’s never been dropped and out of the case looks as new as the day I got it. Yesterday it was working perfectly until midday. After lunch, I put the phone on my desk. I reached for it about an hour later and the touch screen will not respond. I looked at trouble shooting, did a reboot and tried without the protective screen with no result. One small side will respond on the log in screen…the back button. No other area of the screen will respond to touch. I am now locked out of my phone. Please advise. Thank you. — Jim

Solution: Hi Jim. In older Samsung flagship phones like the S5, an issue like this can easily be fixed by simply removing the battery. Since your S7 has a non-removable battery, you only need to simulate a “battery pull” by doing the following steps:

  1. Press and hold the Power (located on the right edge) and Volume down buttons (located on the left edge) for 12 seconds.
  2. Use the Volume down button to scroll to the Power Down option.
  3. Press the Home key to select and wait for the device powers down completely.

Problem 3: Galaxy S7 won’t install update, won’t turn back on

Hi. My phone came up with an update to its operating system. I work on a ship and even though we have wifi onboard, it often drops out or times out. A while later my phone was frozen. I have tried a soft reset and it came up with the blue screen saying initializing which looked like it was trying to continue the update but it wasn’t connected to the internet so just froze again. I then got to the blue warning custom install operating system screen so i pressed down to cancel. It then went back to Galaxy S7 screen and froze. After a couple of times resetting and nothing happening i clicked yes to manual OS update and then tried to reset again. No change there. Now there is nothing but a black screen and when i plug it in to charge there is no LED and whatever button i press nothing happens.

I have tried the home and up button then the power button method but no change there. I have tried the power and down and home together or just trying to hold the power button but nothing seems to want to work. Please help. Any information appreciated. — Chris

Solution: Hi Chris. First, you want to make sure that this is not charger-related by using a known, working charger. Make sure to use a different USB cable too if possible. If you have a wireless charger, you can also try that. If the phone remains unresponsive, you’re out of luck. The problem is most likely bad hardware. Some of the common hardware failure that can cause boot failure includes the following:

  • bad charging port
  • malfunctioning power IC
  • damaged motherboard

We don’t know much about your system to help you pinpoint the most likely cause of the problem but if this device has been physically impacted or damaged, exposed to water or thermal shock, stop looking for software solutions. Instead, have it checked by a professional so you’ll know if it can still be economically repaired (yes some repair can cost almost as a new phone itself).

Problem 4: Galaxy S7 messaging app keeps sending duplicate SMS

Hello. Ever since my phone did the most recent update (beginning of May 2017), my messaging app has been sending duplicate text messages. I’m using the Verizon Message+ app, and when I send messages, it stays on “sending.” meanwhile the person who I’ve sent it to, has already gotten it. When I restart my phone, and also just at random times, it resends the text. At that point it’ll then say “sent” & “delivered”. Sometimes the messages are going through more than once.

Another issue I’m having with the texting is, that I have it set up to beep up to 10 times in my notifications. Ever since the update, I only receive 1 notification (even though I have it set to notify me 10 times). Everything was working well, until I did the latest update. I am hoping you’ll be able to help me fix this issue. Any assistance would be greatly appreciated! — Donna

Solution: Hi Donna. App or system behaviors can sometimes changes after installing a system update either because that’s how developers intend to, or a bug has developed afterwards. To see if your concerns are due to a bug, you must do relevant software troubleshooting. Below are the things that you must do.

Clear the messaging app’s cache and data

This should be the first thing that you want to do in this case. This will ensure that the messaging app’s settings are set back to their defaults. Here’s how it’s done:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Data and Clear Cache buttons for the application.

Wipe the cache partition

Should clearing of messaging app’s cache and data won’t fix the issue, your next move is to refresh the system cache. This is done by wiping the cache partition. Here’s how to do it:

  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.

Perform a factory reset

If both steps above won’t solve anything, you must do a drastic step called factory reset. Here’s how it’s done:

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  2. Turn off your Samsung Galaxy S7.
  3. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  4. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  5. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  6. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  7. Once highlighted, you may press the Power key to select it.
  8. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  9. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  10. The phone will now reboot longer than usual.

Problem 5: Galaxy S7 keeps overheating and restarting when using Google Maps

Hi. I have purchased a phone via less than one year ago and the phone now is restarting itself and heating up when Google maps/Navigation is run. The phone seems to be manufactured for UAE, model is SM-G935FZDUXSG. I have run it in safe mode, cleared the cache and finally in one of the local Samsung stores the factory reset was done. All was good for a while, until I have started Google Maps. The phone then went into a loop restarting and I have to turn it off permanently, as it is not possible to have it even in safe mode now. I spoke to Samsung support here in Ireland and the UK but I was told that since the model is a non-European one, they don’t have the parts for it here and won’t take it for repair. Any help is much appreciated now. The phone is still under the one year guarantee. Thank you very much in advance. Sincerely yours. — Stefka

Solution: Hi Stefka. We want to make one thing clear here. Factory reset is supposed to eliminate bugs that may have developed overtime or out of nowhere. This is done by simply erasing everything — apps, updates, and user data such as photos, videos, music, documents, etc. — from the system and returning all software settings to their basic setup. The only thing that should remain after a factory reset should be bare operating system version and pre-installed apps. In some firmware versions, Google Maps app is part of the pre-installed apps. If your phone comes with a pre-installed Google Maps app and it’s not working properly after a factory reset, then the problem probably lies in the operating system. This means that there’s coding problem with the current operating system running on your device. Since you can’t fix a coding issue, you must report the trouble to the developer of said software. If you download system updates by air, you must contact your carrier about it. On the other hand, if you flashed a custom ROM or unofficial software from somewhere, it’s your responsibility to make the problem known to the developer.

If Google Maps was not part of your phone’s pre-installed apps, make sure to observe how it works after a factory reset when there’s no other apps installed. If it works properly, that’s proof that one of the third party apps is causing a conflict with Google Maps app.

Problem 6:  Galaxy S7 edge stuck in T-Mobile logo screen, won’t turn on

Good evening. I took my Samsung Galaxy S7 Edge to get its screens fixed because I had accidentally dropped it & both of the screens (front & back) were damaged. The whole process to get both of the screens fixed took almost a month. The store always kept giving me some type of excuse as to why the phone wasn’t ready yet.

Now that they finally returned the phone to me, there are even worse problems with it. The phone was returned to me yesterday (Monday 5/15) & it was working fine for about 30minutes. When I tried to send a text message, the message would take about 5 minutes to send or sometimes it wouldn’t even send at all. By the time I noticed the problem the store was already closed.

On my way home I tried to make a phone call & the phone turned off completely. I didn’t really think much of this because it had low battery so I thought that it was just the battery. Once I got home I decided to put my phone to charge. When I noticed that it had enough battery for me to use I tried to turn it on but the phone wouldn’t turn on.

About 10 minutes later, I saw the screen light up with the carrier logo which is T-Mobile so I thought that the phone was finally turning on, but that never happened. The screen stayed with the logo of T-Mobile the whole time, it never changed at all. I couldn’t even turn off the phone. It also got very very hot until eventually the battery ran out again.

Today Tuesday 5/16, I took the phone to the store again to explain to them what had happened & they told me that the phone needed a “software” & that it would be ready in an hour. I decided to leave the phone with them again. I went back to the store about 4 hours later & they told me everything was ready to go. I turned on the phone in front of them, I made a phone call & sent a text message just to make sure that those things were working & they were. I was really happy because I FINALLY had my phone back & everything was working perfectly. When I got home I started to charge my phone again because it had low battery. The phone worked fine for about an hour & after that it started to give problems again. It turned off & when I tried to turn it back on the screen lighted up with the T-Mobile logo. It stayed that way until the battery ran out & it completely turned off.

Do you have any idea what this might be? Do you think that the store did something to it that made the phone this way? I’m very disappointed and angry. I don’t know what to do anymore. This had never happened to my phone before.

I will take it to the store tomorrow AGAIN to see what they tell me this time. If you can help in any way by telling me what this might be or the reason why this is happening I will greatly appreciate it!! I will be waiting for your response. Thank you so much! Have a good evening. — Yoselynhuezo

Solution: Hi Yoselynhuezo. Dropping your phone however low can potentially damage the hardware permanently. That the screen was damaged by the fall is an indicator that the device was subjected to enough shock that may have loosened or some components or damaged the motherboard. Like water damage, the unnecessary shock from a drop can lead to all sorts of damage which may or may not become apparent during repair. Even if an attending technician can fix the screen damage, other components must have been left in their damaged state because you’re now experiencing problems. Sending your phone for repair does not always guarantee a full fix because not every component in the motherboard can be checked. Doing that is not only difficult but very time consuming, requires specialized tools that may only be available for Samsung technicians, and too costly in terms of time and materials. These are the reasons why Samsung would prefer phone replacement over repair in a number of cases.

As far as knowing what may be causing your phone to overheat (and not boot up normally) is concerned, there’s nothing much that we can do to help. The entire operation of the device starting from its boot up stage to the loading of the operating system is like a chain that involves both hardware and software. A break in the chain can render the entire boot up process broken. We don’t know what the store’s technician did to your phone’s software and hardware. The phone’s failure to boot may be due to a software glitch or bad hardware. If the store is not transparent enough to tell you what’s wrong with the device, you may be left in limbo. Sadly, there’s nothing much that you can do about it. At this time, the only leverage that may be able to use against them is to threaten a refund request. That won’t fix the problem on your phone though.

If possible, try a second opinion by having your phone checked by another professional.

Problem 7: S Note won’t load in Galaxy S7 after its update was interrupted

Hello. I have had my S7 for about 3 months. Yesterday I updated it to the Nougat operating system. I opened my S-Note and it asked if I wanted to update it. I started to and then canceled it because for some strange reason I thought it would use up a lot of the wifi at work. Now, it won’t run the app. It opens, but I cannot edit any of my notes or use the back button. It then closes the app automatically. I’ve tried to empty the cache both ways, by using the volume, power, & home buttons as you describe on your website and also by going into the app manager and doing it directly. Neither way has fixed the problem. Can you help? — Darren

Solution: Hi Darren. Interrupting your device while its installing an update is a sure way of corrupting an app or software. To prevent this from happening in the future, be sure to allow your device to finish updating first.

Now, if clearing S Note app’s cache didn’t fix the problem, clearing its data should. If you’ve already deleted the app’s data before contacting us, your next move depends whether or not it’s a pre-installed app or not. If S Note came with the device when you first set it up and wiping its data didn’t fix anything, you should do a factory reset. Refer to the steps above on how to do this step.

If S Note was added at a later time after you’ve set your phone up initially, you must uninstall it from the system first before attempting to re-install it. If that won’t work either, factory reset the phone.
