Problem #1: Galaxy S5 sound is low when using a headset

I bought a new Galaxy S5 for Verizon a few days. When I turned it on, it connected to Google and Wifi. The updates began, and when I tried to listen using my wired headphones post the updates, the sound was low even when Media volume is highest. There is static and cracking noises (only when using the wired headphones, tried several different ones, no issue with the speaker when the headphones are out).

When I listen to a high quality mp3 using the headphones, the sound is very “thin” – i.e., no bass, the singer’s voice is barely audible, and you only hear the arrangement – as if some frequencies are absent.

Also, when I change the volume up and down a Google Voice recognition pops up expecting some action, even though I explicitly turned it off “OK Google” detection in Settings.

When I cleared the defaults, changing the volume up and down at times pops up the box below with: “Do you want to open with Google App or S Voice”? As if the microphone is reacting to the audio when the headphones are in, which is very strange. I disabled all the Motions and Gestures in Settings.

I tried the following to fix this problem without any success:

1) Cleared the cache partition

2) Removed and inserted back the SD card, battery, restarted the phone many times

3) Did a factory reset (it rolled back some updates, but not Android 6.0.1.)

4) Disabled/enabled Google app, re-installed YouTube and other key apps

5) Started in the Safe mode – same issue persists.

Perhaps something is wrong with the phone jack (I tried inserting the headphones better, cleaning it with air, etc., but I still suspect a software issue of some kind, based on how it works).

Any ideas would be greatly appreciated! — Leonard

Solution: Hi Leonard. An audio problem like this can only be fixed if proper isolation is done first. We suspect that the problem is not software-related since you’ve already tried to do a factory reset. While Android system updates can sometimes lead to problems, they don’t normally affect how a hardware works because their drivers remain unchanged. In fact, we haven’t had any case documented before demonstrating that a headphone jack stops working properly after a system update.

If the problem does not occur when inserting the same headset to another device, you can rule out a headset issue. Headphone jacks can sometimes go bad, even on other electronics so the best thing that you can do right now is ask for replacement phone from your carrier.

Problem #2: Galaxy S5 loses Wi-Fi internet connection after an update

Hi. I did the system update through the phone as it downloaded automatically through wi-fi at work. Since then I have had no internet connection at all.

I have tried a soft reboot. Did the reboot deleting the cache.

Still no network connection. Network is definitely on when I turn off wi-fi.

Also went to the SIM card provider,, who sold me sim card in January and they can’t see anything wrong and it says I have internet credit. The setup is correct and they tried a new connection. This has all happened since the update. Connects to wifi fine! just no internet whatsoever. I am going to try another SIM in the phone tonight after work but am at a loss. Last option is a full system reboot to factory settings I believe so am backing up everything today while I am on wifi at work.

I am hoping you will come up with something so I don’t have to do that. Data network is definitely active. I’ve tried taking battery out as well as turning on and off multiple times.

Thank you for any help you can give me.

Regards. — Toni

Solution: Hi Toni. There are only two things that we recommend if you encounter problems right after updating Android — wiping the cache partition and performing a factory reset. Assuming there’s no hardware problem involved, like a malfunctioning Wi-Fi radio, a factory reset should help you bring back Wi-Fi connectivity.

Problem #3: Galaxy S5 won’t connect to StraightTalk mobile data

I bought a Samsung Galaxy S5 used and bought an accompanying “bring your own phone” package. Everything set up fine and I used it for several months without issue. Recently there was a software update available which I started. There was a problem and the phone ended up getting turned off. The update was then failed and the phone would then only show me the screen saying that the update had failed and I needed to run the Verizon Software Upgrade Assistant (the repair portion) to repair the phone and finish the update.

After a few failed attempts, the repair assistant finally worked overnight while I was sleeping. The phone was usable again. It sent and received texts and calls and hooked up to wi-fi fine but will not connect to the internet via data.

When I go to look at the APN it shows VZWINTERNET and only that one. Doesn’t give me the option to add others either. (plus sign is gray and unclickable).

So I tried having StraightTalk update my APN and data settings but it shows up as an incompatible SIM, even though it is absolutely the same StraightTalk SIM I’ve had and was working.

Did the repair assistant mess up my SIM? Is there any way to fix it or do I now need a new SIM? Thank you in advance for your consideration. — Scott

Solution: Hi Scott. Verizon phones are notorious for giving problems to users if used on different networks. We can’t be sure if the Verizon update is responsible for the present issue so you have to talk to StraightTalk support for guidance.

Trying another SIM card is definitely a must in order to isolate the problem. If the second SIM fails, that’s a confirmation that some settings may have changed that prevents the phone from connecting to StraigtTalk’s services. Because we don’t know the full history of your phone, we can only speculate. You must work closely with your carrier to get this issue resolved.

Problem #4: Galaxy S5 screen keeps flickering if phone is not connected to charger

After I uninstalled those two apps (Game of War and Clash of Clans. Installed them to get free stuff and then un-installed then phone started freaking out), I was recording a video on the camera. It suddenly shut off and then started flickering to the black start up galaxy screen off and on. It shows the galaxy screen and vibrates once like its starting up and then starts over doing it over and over but never fully turns on. 

I pulled the battery twice letting it sit for about 20 seconds and when i turned it back on it starting flickering again. I plugged it in even though I knew there was about 35% battery life and it started up and was working fine but only while charging. I went to bed and let it charge. When I got up this morning, as soon as I pulled it off the charger it started doing it again. It continues to flicker back on that screen every time if I don’t keep it on the charger. I did clear the cache but that didn’t help. Please help.  — Stevie

Solution: Hi Stevie. If the only you did prior to noticing the problem was to install the said apps, the best thing that you can do right now is to do a factory reset. Doing so will erase any glitch that may have developed after the installation. Here are the steps:

  • Power down the Galaxy S5.
  • Press and hold the Volume up button, the Home button, and the Power button together until you see the Android on screen.
  • Use Volume down to highlight the wipe data/factory reset option and press the Power button to select it.
  • Use Volume down again to highlight Yes – delete all user data and press Power to select it.
  • Use the Power button to select Reboot system now.
  • When the S5 restarts it should be completely wiped and ready to set up again.

Problem #5: Calls sound muffled using a Galaxy S5

Hello. I’m desperate. Found your site on Google. Didn’t see my problem so I’m writing hoping you still are active with site.

I have a Samsung Galaxy S5. Not sure if Android version is Lollipop. It doesn’t say.

Anyway I just turned phone in, because no one can hear me and when they do they say I’m “muffled” or sound like I’m in a “washing machine.”

Most times I have “2 bars” for my phone. When I received “new” phone, I still have “2 bars” most times. Does not matter where I am. I could be in middle of town where a tower is visible.

Anyway, my girlfriend has an iPhone and she can walk through out my house with no problems, like she is on a landline. I’m ready to either try another phone brand or phone company. Do you have any suggestions?

One more thing. When I talk on the phone, the phone at time puts my volume on “vibrate,” or my “settings” menu pops up. And if I text or hang up on call most times it will call person back. I’m at my wits end with this. Thanks for any help you can offer. — Dennis

Solution: Hi Dennis. The first thing that you want to do is check if the call problem you’re having is due to a bad microphone. To do that, try to record your voice using the phone and listen to it. If the audio is bad and sounds like the line is full of static, that’s an indication that you have a  hardware problem. The only solution is to ask for a replacement device from your carrier or Samsung.

If the microphone works fine though, consider doing some basic software troubleshooting. The first one that you can try is wiping the phone’s cache partition. This troubleshooting step is usually recommended if you have updated a device to another operating system version or if the phone is having some weird glitches. Despite not having installed the full set of new operating system files, we suggest the you do the following steps to erase possibly corrupted cache on your device:

  • Turn the phone off.
  • Press and hold the following buttons together: Power, Volume Up and Home.
  • Release the buttons once the Android system recovery menu appears.
  • Use the Volume buttons to navigate to Wipe Cache Partition option.
  • Press the Power button to confirm selection.
  • Select Reboot System Now option after deleting the cache. Wait for the phone to reboot.

You can also try booting the phone in safe mode to see if a third party application is the problem. While in this mode, your phone is put in a diagnostic state, allowing only first party apps to run. This is mostly performed if a user suspects that a third party app may be messing with the operating system, or if the phone suffers from performance issues. If your calls work just fine while in safe mode, that’s a confirmation that one of the apps you installed is the root of the problem. Just follow these steps:

  • Turn the device off.
  • Press and hold the Power key.
  • When ‘Samsung Galaxy S5′ appears on the screen, release the Power key.
  • Immediately after releasing the Power key, press and hold the Volume down key.
  • Continue to hold the Volume down key until the device finishes restarting.
  • Safe mode will display in the bottom left corner of the screen.
  • Release the Volume down key when you see Safe Mode.

If nothing changes after doing these procedures, do not hesitate to do a factory reset.
