Problem #1: Galaxy S6 Edge keeps showing the charging screen

I have a Samsung Galaxy S6 Edge. I bought it last year, and I haven’t had a single issue with it – until recently. I was sitting on the couch, browsing a forum I have browsed often, when suddenly my phone went completely black. I didn’t drop it. It didn’t get wet. I was literally just sitting there and it stopped working. My husband was able to restart it, but after that it was glitching so badly it was barely usable. I was constantly having to restart it and it seemed to get really hot really quickly. Finally I got fed up and did a full factory reset. At first it didn’t seem to work, but after a day or so it was noticeably much better – I may need to restart once or twice a day but better. Then today my phone died at work. It’s died since these issues started and charged just fine, but today when I plugged it in the charging icon started just flashing on and off rhythmically. I could get it to go to download mode, but when it gave me the option to continue or restart, hitting restart only brought me back to the flashing icon. I tried different chargers, even our car charger, with no success. Now it’s indicating that it’s fully charged even though it hasn’t been nearly enough time. I just tried to turn it on and got the power on screen, but then it goes back to the flashing charge icon and then the fully charged one a second later. What the hell is going on? Is there anything I can do? — Nakita

Solution: Hi Nakita. In case you don’t know, most of the solutions available for an Android user are software in nature. This means that if you’ve already tried doing all the basic software solutions (like the ones you mention above) and there’s no positive result, the problem might be caused by bad hardware. Try having the phone checked for hardware issues or simply replace it.

Problem #2: Galaxy S6 Edge keeps showing OK Google popups when headset is inserted

Hello. I used the Samsung headphones on my S6 Edge device without a problem for about a week. Once it started with a problem of the OK Google going on any time I inserted the headset, and I was simply unable to use Youtube, or answer my calls. In the meantime the volume control stopped working, the pause button is not working either. In the meantime I switched off OK Google (although it went on without me switching it on at all), and it solved one part of the problem. Volume control, pause still don’t work. I read many forums, many are facing the same problems, but no solutions offered. Kindly advise. Thank you. — Kinga

Solution: Hi Kinga. An issue like this is caused by a bad audio port. Try checking the port itself for possible visible obstruction or dirt and clean it. If that won’t change anything, do the basic software troubleshooting like booting in safe mode or factory reset. Any of these two software procedures will not fix a bad audio port but will help in isolating if the cause of the problem is software or hardware in nature.

For reference on how to do the procedures, check the details below.

Boot the S6 to safe mode. This procedure is not a solution per se as its main purpose is to check if the issue is being caused by a third party app or not. While in this mode, no third party app will be allowed to run. If one of your apps is the cause, the issue should not occur. To boot your phone in safe mode, follow these steps:

  • Press and hold the Volume Down and Power keys for 20 to 30 seconds.
  • Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
  • Your phone should continue booting up and you will be prompted to unlock your phone as usual.
  • 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.

Boot the S6 to factory reset. For serious firmware-related issues, the factory reset is often the ultimate fix. It’s because it will bring the phone back to its factory defaults deleting all files, data, settings, apps, personal information, accounts, etc. In short, if there are things you don’t want to lose during the process, you must back them up prior to performing the Factory reset.

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

If nothing will change after doing these two software procedures, you can bet a hardware malfunction is to blame. Contact Samsung so you can have the phone repaired or replaced.

Problem #3: Apps on Galaxy S6 keeps saying no connection

Over the past few months my phones connection has been acting up, when either on Wi-Fi or 4G. Internet-based apps like Youtube, Facebook, Tumblr etc lose connection regularly. For example while on YouTube after watching a video for a few minutes i go to click on another but it says “no connection” at the bottom. Facebook says the same. I go to watch a video or refresh and it says “no connection”. My Spotify will play a few songs in the queue and then will not play the next one but when i open the app back up it starts playing the song. Any help? — Sam

Solution: Hi Sam. Wiping the cache partition may fix your issue.

For minor firmware-related issues brought by apps and firmware updates, wiping the cache partition often does the trick. It’s because this procedure will literally delete all cached files in the cache partition, which will force the system to create new ones during the next boot up.

This procedure is also very helpful in fixing issues like random reboots, boot loop, stuck during boot up and random freezes after updates. Here’s how you wipe the cache partition on your S6 Edge:

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

If wiping the system cache won’t help, make sure that you delete the cache and data of each app in question. Here’s how to do it:

  • Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  • Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  • Once in there, click on an application.
  • 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.
  • You should now clearly see the Clear Data and Clear Cache buttons for the application.

Finally, don’t hesitate to factory reset the device if the issue persists.

Problem #4: Sprint Galaxy S6 bootloop issue

Hi Droid Guy! I have a Samsung Galaxy S6 (32GB on Sprint). I just upgraded to Android 6.1 and not long after the phone has started to boot loop. never have rooted the phone and it is fully stock and just getting the OTA updates. I did a lot of research and these are the options I have tried to fix it:

  1. Empty Cache
  2. Master Reboot
  3. Re-flashed manually using ODIN3

After I re-flashed it continued to boot loop. I re-did the empty cache/master reboot and was able to get it to the first screen, log in to wi-fi, then to the screen where it says “preparing phone for use” and that’s where it is rebooting at now. Any ideas on what is causing this and how to fix it? Thank You. — Casey

Solution: Hi Casey. There’s only so much that you can do about this problem. That the basic software troubleshooting (which includes manual flashing) did not help is a clear indicator that the issue can not be fixed on your end. Find a way to have the phone replaced.

Problem #5: Galaxy S6 resets all settings back to default after installing Android Marshmallow

Yes. after I did the system update on accident, to the Android 6.0 Marshmallow, my phone has been restarting by itself. It will restart the whole phone to where it takes off my camera icon for lock screen. I have military time and it takes that off to the normal time zone, it resets my notification panel, it takes off my lock screen picture and it takes off the battery percentage indicator off. It’s becoming annoying and I need it to stop. I don’t have time and patience to keep re-doing everything on my phone just because it has to restart itself for no reason. Can someone please help me? I don’t know why it keeps doing this. I uninstalled apps I don’t use, apps that just came with the phone like all the music apps I uninstalled. Does anyone know how to fix the problem and to have my phone stop restarting its self all the time? — Cagirl0104

Solution: Hi Cagirl0104. If this problem started happening ONLY after installing an Android update, then you may be able to fix the problem by wiping the cache partition and performing a factory reset. Refer to the steps above on how to do them. Also, make sure that you only install compatible apps. Remember, outdated or incompatible apps can create conflicts with the operating system, which can manifest in erratic phone behaviors.

Also, make sure that you are installing the correct firmware for your device. You should only install OTA (over-the-air) updates from your carrier. If you manually flash a non-carrier firmware, there’s a chance that you may have installed a buggy version or even an incompatible one.

Problem #6: MMS on Verizon Galaxy S6 not working when on MetroPCS network

Hi. I recently switched from Verizon to MetroPCS. I have a Samsung Galaxy S6 that I purchased from Verizon so it has all the Verizon software on it. I now use the MetroPCS SIM card they gave me. I make calls, and use data without issue. I am able to send and receive messages via the Messages app the phone came with from Samsung. However I am unable to send or receive MMS messages. I have followed your steps to resolve the problem to no avail. This is the list of steps you posted: Name: MetroPCS APN: Proxy: Not Required Port: Not Required Username: Not Required Password: Not Required Server: Not Required MMSC: https:// MMS proxy: leave it blank MMS port: leave it blank MCC: 310 MNC: 16 Authentication type: Just leave the default settings there The MNC 16 does not allow the change to be saved. It was set to MNC 260 and that is the only number that allows the save of the MMSC address. I even contacted MetroPCS and other sites that also recommended using the MMSC address of and again this also does not work. Can you help? — Tony

Solution: Hi Tony. This is the usual issue many users encounter when using Verizon phones with other networks. If you already called MetroPCS  and they’ve verified that all the APN settings are correct, then the problem might be something deeper in the operating system. That means that you won’t be able to use MMS on this phone unless it’s using Verizon network.
