Galaxy S7 loudspeaker randomly muted

Problem: I damaged my Bluetooth headset last week so I have to listen to music using the loudspeaker then I discovered that randomly the sound is muffled. I don’t see a pattern and I tried playing the tracks that were muffled on my computer but they seem fine. So, I played them again on my phone and they also played fine. Other tracks get muffled randomly so I think the problem is with my phone. Have you guys encountered this problem before? How do I fix this?

Answer: Based on your description, I think the problem is with the speaker itself. It happens when the speaker is covered or pressed the thing is we cannot open the phone to inspect it. So, all we can do is rule out the possibility that it’s caused by apps or the firmware and then have the technician take a look at it. I suggest you boot your phone in safe mode first and try to play music while in that state…

  1. Press and hold the Power key.
  2. As soon as you can see the ‘Samsung Galaxy S7’ 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 the audio is still randomly muffled and if you’re determined to get it fixed, I suggest you reset your phone before sending it in for checkup and/or repair. Of course, backup your data and files before following these steps:

  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. 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 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.

I hope this helps.

Galaxy S7 text notifications no longer play when messages come in

Problem: After an update, my Galaxy S7 doesn’t notify me of received text messages anymore; it just won’t play the usual messaging tone. I am sure that everything was working prior to the update as I was texting somebody when the update notification come in and I was receiving messages with the tone. But after the update, the sound just won’t play. How come? Can this be fixed?

Solution: There’s a setting you need to change so that the notification will again play. Follow these steps and set necessary changes:

  1. From the Home screen, tap the Apps icon.
  2. Find and tap on Settings.
  3. Touch Applications and then Application manager.
  4. Swipe to ALL tab.
  5. Find and touch Messages.

Galaxy S7 can no longer detect my old Bluetooth headphone

Problem: I have an old Bluetooth headphone that I’ve been using with my Galaxy S7 for months now. It always worked until recently when an update arrived. I really didn’t have a choice but to download the update and after that, the phone and the headphone can no longer pair. They can still detect each other but can’t pair. What should I do?

Answer: It could have been easier for us to give you an explanation if you included the brand and model of the headphone you’re trying to pair with your phone. You see, the Galaxy S7 is the latest flagship from Samsung and it comes packed with up-to-date technologies including Bluetooth. So, my point here is that your headphone may no longer compatible with the phone’s Bluetooth version. Try to pair your headphone with other phones, if they can be paired successfully and get connected, then the issue might be with your device, however, you also have to rule out such possibility.

Therefore, if possible, try to pair your phone with other Bluetooth speakers or headsets and see if it works fine. If so, then it’s a compatibility issue and there’s no much we can do about it except buy a new accessory.

Galaxy S7 won’t sound off after an update

Problem: After the recent update, my phone no longer plays a sound or there’s no audio in whatever it is I play like music or the notifications. I already tried rebooting the phone many times but the problem isn’t fixed. It’s as if the phone is muted but when I check the volume, it’s set all the way up. I want to know if there’s something I can do to fix this or if it’s caused by other factors and not just the firmware. Help me please. Thanks.

Solution: You’re not the first one to have reported this kind of problem. If you are sure it started after the update, then it’s the cache that may have gotten corrupt. Delete the system cache and everything will be back to normal. Follow these steps…

  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 wiping the cache partition. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.
