Problem #1: Galaxy S7 SMS disappears right after sending it | Galaxy S7 SMS are out of order

Hi. After working normally until today, now when I try to send a text, the message immediately disappears when I press send and it doesn’t appear in my message threads. There is no sent or failed message displayed. The text just disappears. The message is actually sent to the recipient though.

If the recipient replies (or if anyone else sends me a message) then their message shows at the bottom of my messages list — as if it was my oldest message thread (rather than being at the top of the list as my most recent thread). The instant that I click on the message (to fully open it) it disappears and I can’t then find it again whatever I do.

If I use the new message function (compose) and select the same recipient of a text that has just failed in the sense described above, there is no record of the text that I sent to them. I really hope you can help. — Dave 

Solution: Hi Dave. We’ve observed this situation happen if the system date and time are incorrect. Make sure your phone’s date and time are set correctly. Doing so will force the phone to sort your messages correctly. If that won’t fix the problem, try to wipe the messages app’s cache and data. Just follow these steps:

  • 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.

Problem #2: “Unfortunately, software update has stopped” keeps popping up on Galaxy S7 Edge

I have the “Unfortunately, software update has stopped” issue and i tried all the solutions you suggested in your article but nothing worked. I bought this phone (Samsung Galaxy S7 Edge model: SM-G935FD) in Thailand on my trip and since i bought the phone, i have this issue. but in my country (Israel) they don’t support this phone so i have no idea what to do.

And also every 10 minutes this error appears on my screen. — Tal

Solution: Hi Tal. If all the steps detailed in this post, How to fix Samsung Galaxy S7 Edge “Unfortunately, Software Update has stopped” error, did not work, the only other things that you can try includes the following:

  1. Disable the OTA update notification (if available in this particular phone variant)
  2. Force Stop the Software update app.

To do the first one, simply go Settings>About Device>Software Update. This option is usually available for International version of Galaxy phones. If you can’t find an option to turn off system update notification in this phone, you’re unfortunate. You must then try the next logical solution, which is to Force Stop the Software update app. To do that, follow these steps:

  • 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.
  • Find the Force Stop button and tap it. You can do the same thing on the Disable button if it’s available.

Problem #3: Galaxy S7 won’t charge via USB cable

Several months ago the original cord broke and since about 6 months ago I’ve been using a micro-usb 3.0 3rd party cable that seemed to have no problems. My problem now is that my phone will not be charged using any combination of cable and anchor. I always get the message “charger not compatible so charging was stopped, use original charger and cord” (I’m paraphrasing there). I went to a shop and they looked in the port for damage or debris, but they didn’t find anything significant. They also checked the charge on my battery and it looked fine. I did a factory reset, and the problem persists. I called Samsung and they suggested clearing the cache, which I did, and it didn’t help. I bought a new Samsung charger and I still get the same message. Samsung said I can’t send it in because they’re overworked with the S7 warranty issues, but maybe in a few months. I really don’t know what to do next. — Laura

Solution: Hi Laura. We suggest that you try factory reset first to see if there’s an unknown software glitch causing this trouble. Here are the steps:

Create a backup of your important files and contacts.

  • Turn off your Samsung Galaxy S7.
  • Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  • When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  • Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  • Once highlighted, you may press the Power key to select it.
  • Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  • Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  • The phone will now reboot longer than usual.

If the phone continues to refuse charging via USB cable, there may be a hardware issue inside causing the problem. If you don’t want to send the phone to Samsung at this time for repair, try using a wireless charger instead. Otherwise, you have no choice but to call Samsung again and demand that they either fix the phone or replace it.

Problem #4: Galaxy S7 not detecting 2 SD cards

Hello, This is my first Android Phone. I don’t understand it’s OS fully yet, but I can usually figure these things out. I have a known good (Kingston Brand) 32 GB Micro SD Card which is “Speed 10” I’m told. The Micro SD Card does indeed have a ’10’ icon on it. It is formatted in default “FAT 32” file system. The phone completely ignores the presence of the properly inserted 32 GB Micro SD Card. Tried installing a new 8 GB Micro SD Card, still, phone doesn’t notice new 8 GB Micro SD Card either. This phone is in “used, excellent condition,” (a Kijiji purchase). Previous owner claimed no issues with phone and to have done a (factory?) reset of the phone. He seemed sincere. I have a working Telus SIM card in this phone (for texting only, no data). All features, except for accessing the Micro SD Card, seem to work flawlessly. Have I overlooked something?

If I need to perform a Factory Reset, (how) can I back-up my phone’s Contact List & certain apps first? Sincerely. —  AL

Solution: Hi AL. That the phone does not detect at least 2 SD cards is clear proof that it’s defective and no amount of “claims” from the previous owner can refute that. If you’re 100% positive that both SD cards are working (because they work on other devices as well), then you can assume that your phone’s S7 may have a defective SD card slot, or a bad motherboard. To fix the issue, you must send the phone to Samsung so they can check the hardware.

If you want to do a factory reset, you can save your contacts to a computer via Smart Switch. There are also other third party apps in Google Play Store that can do a similar job. You can start with Helium – App Sync and Backup.

Problem #5: Galaxy S7 Active screen flickering and pixelation issue after installing an update

All started on my S7 Active after last update. First sign of trouble was during texting the screen started pixelating and jumping around where typing was impossible as screen would split in half or keyboard would jump up or only show half of it. Then during a call the phone would make a noise and reboot and icons disappeared from screens. Took to AT&T store but of course they acted clueless and no help at all. Tried deleting some apps and moving some to SD card as memory was 65% used and thought that might help. Nope. Then tried clearing the cache partition per your advice. Seemed to help slightly but still reboots and screen freezes or pixelation. I then tried factory reset and phone still having issues. Started in safe mode a couple times to no avail, phone still isn’t working right and restarted itself and became warm quickly and drained battery quickly as well. So po’d at Samsung doing this to a phone that was working fine. Any ideas? Thanks for your time and any assistance. — Shawn

Solution: Hi Shawn. That the issue keeps happening even when you enabled safe mode is a sign that there’s no issue with third party apps. We don’t know the full history of your device so we’re assuming that there’s no hardware issue involved. Sometimes, screen pixelation can be a product of a damaged screen after a user dropped a phone or exposed it to liquid or extreme temperature. If your phone has never been physically damaged before, then the issue may be due to a poorly coded firmware you installed. As a workaround, you can try to manually flash the previous Android OS version but this entails that you root the device first. Rooting is relatively safe to do but there are inherent risks involved. It can also expose the phone to unnecessary security risks if you’re not careful. If you don’t want to manually install the previous OS version, you must contact Samsung so they can flash the software themselves. If you updated the device via a carrier-provided OTA update, make sure that you let your service provider know about the issue so they can also help. Better still, simply demand for a replacement phone if this option is still available.

Problem #6: S Voice keeps showing up when headset is plugged in to Galaxy S7

Hi. I have a Galaxy S7 I bought about three weeks ago, and yesterday for the first time I tried to use headphones. It turns out anytime I try to listen to anything through the headphones the phone activates the voice commands. it plays two seconds of the thing I’m trying to listen then stop and open S Voice (and even after I disable S Voice in the phone it opens Google commands/searching by voice). If I just plug the headphone nothing happens. But when I start playing something (anything, videos, games, voice messages, music) it plays for 2 sec and open voice commands. It makes impossible to use headphones, is quite annoying. — Tefitefinha

Solution: Hi Tefitefinha. The first thing that you want to do is to wipe the cache partition to force the phone to refresh the system cache. Here’s how to do that:

  • Turn off your Samsung Galaxy S7.
  • Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  • When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  • Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  • Once highlighted, you may press the Power key to select it.
  • Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  • Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  • The phone will now reboot longer than usual.

If wiping the system cache won’t help,  do a factory reset (refer to the steps above).
