Problem #1: Solutions to Galaxy S7 black screen issue

Screen started showing up colored shadows in the background. They interfered with reading the screen. Then it became blotches of black lines as though someone had taken a pencil and started scratching out the pages. They did not let one read anything on the screen. Eventually it became a totally black screen with nothing on it.  This process took about an hour from start to finish. — Margarita

Solution: Hi Margarita. If your phone’s screen remains totally black but you can hear notifications for incoming texts or feel the device vibrate when you try to restart it, that’s a sign that the issue is isolated to the screen. An issue like this cannot be resolved by turning the phone on and off, or by booting the device to any other modes like safe mode, recovery mode, or download mode. That’s because a black screen issue is usually a result of a hardware damaging event like a drop, water/liquid exposure, or, in some rare cases, screen assembly end-of-life.

Since you did not give us any background on what happened before noticing the issue, or what you think might have caused the phone to lose screen functionality, we can only speculate here. While some types of software glitch can also cause the phone to crash and temporarily show a black screen symptom, a user can normally still reboot the phone in another mode. If you haven’t tried restarting the phone in other modes, we recommend that you check if the screen turns on safe mode. We normally suggest booting to safe mode if we think that a phone has a problem with a third party application. However, you can do this in your case as well. Here’s how:

  • Press and hold the Power key.
  • As soon as you can see the ‘Samsung Galaxy S7 EDGE’ on the screen, release the Power key and immediately hold the Volume Down key.
  • Continue holding the Volume Down button until the device finishes rebooting.
  • You may release it when you can see ‘Safe mode’ in the bottom left corner of the screen.

If the screen remains black after doing the safe mode routine, try to boot to recovery mode next. In this mode, you will have the option to wipe the cache partition, do a factory reset, or simply reboot the phone. If your S7 reacts to the hardware button combination to boot in recovery mode, the cause of the problem is most likely software in nature. Otherwise, you must have a hardware malfunction. To boot in recovery mode, just follow these steps:

  • 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.
  • When the Samsung Galaxy S7 Edge 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.

If the phone won’t respond after pressing and holding the Home, Volume Up and Power keys, you can safely assume that the screen may have been damaged for some reason. If you dropped the phone prior to noticing the problem, there’s high likelihood that the screen assembly may have been dislodged or some components broken. Water damage can also damage any part of the screen. Either case, your best option is to seek professional help in figuring out where the damage lies. Only after knowing what part is affected will you know if it’s worth repairing. Screen repair or replacement can be expensive and may cost you over $200 in the least.

Problem #2:  Delays in sending SMS/text messages on the Galaxy S7

Sometimes my texts don’t go through and it’ll say “sending”. About half the time, the text eventually goes through but half of the time it doesn’t and an error message appears notifying me that it didn’t. The same happens with MMS. Lately, when this happens, I turn on airplane mode and turn it off after a few seconds. This does seem to help but not always. When it does happen, I have then it verified that I am connected to the network. When I try to make a call, however, it doesn’t go through either, even after I see I’m connected to the network from the logo on my phone’s home screen. Then I have tried calling my phone and my phone won’t receive the call. It seem like I’m not connected to the network even when my phone says I am. — RSB

Solution: Hi RSB. Text messaging issues like this can be caused by one of a number of things so let’s check them one by one. Don’t forget to send a text message to your own number after each troubleshooting step to see if you have resolved the issue.

Restart the phone

While it’s not accurate to say that a phone gets tired after being left on for a long time, refreshing the system might very well fix the issue. Letting the device do away with temporary files that may have clogged the cache by turning it off for at least a few minutes can sometimes work wonders. There’s no exact science why this works at times but doing it on your end might very well help fix the issue. If possible we suggest that you turn the phone off  for a few minutes every other day to keep the system in good working order.

Uninstall apps or update

If the issue started to appear after installing an app or update, considering checking if removal of said app or update will help. While it may just be coincidence, there are also some cases wherein an app or new update creates a conflict with other apps or operating system. If you can remember installing an app update prior to the start of the issue, try to go to app info page and uninstall the said app. Here’s how:

  • Go to phone Settings menu.
  • Navigate down to “Apps” and tap Applications or Application Manager.
  • Once in there, click on the app you previously updated.
  • 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.
  • Look for Uninstall Update button and tap it.

Use another SMS app

If you’re using stock messaging app (the one that comes with the initial phone setup), try using a third party app if only to see the difference. There are many messaging apps available in Google Play Store so just pick one. Use it for a few days so you have enough time to observe how text messaging function behaves.

Delete old messages

After some time, text messages can pile up. Make sure that you delete old conversation threads to make way for more incoming messages. We’re not talking about the inbox here but the outbox or sent messages folder as well. Be sure to keep a healthy amount of stuff in these two folders all the time.

Insert the SIM to another phone

In some rare cases, a malfunctioning SIM card can also be a cause of SMS delay issues (assuming you are in a GSM network). If you have another phone, try inserting your SIM card to it to check how texting works. If sending and receiving of SMS appears normal, you can bet the issue may have something to do with either the phone or the network.

Let your wireless carrier know

If all these stuff won’t help, that’s probably because the issue lies in the network itself. There may be outages that you’re not aware of at this time. Be sure to contact your carrier so they can offer direct assistance.

Problem #3: Galaxy S7 sends text messages but receiver does not get them

Unable to send text messages to my wife’s Android phone. So far, I’ve been able to send and receive texts from other people, and I’ve received hers. However, since yesterday she is unable to receive mine. I have not installed any new software in the last 4 to 6 months. I followed your instructions on your website for dealing with this by booting my phone in Safe Mode, but was unable to send. (My Messaging app showed that it sent by displaying the sent time, but my wife’s phone never received any of the test text messages I sent her.) As far as I know, everything else on my phone works. I am using a Samsung Galaxy S7 on Boost Mobile network. Please advise. Thanks. — Scott

Solution: Hi Scott. This issue has two sides — your phone and your wife’s phone. If your device indicates that your message was sent, and you did not receive any notifications that the sending process failed, then the problem must be on the receiving end. Make sure that you troubleshoot your wife’s phone as well. She may have set some blocking features on her device by accident, or there may be some other reasons like a network trouble or a messaging app glitch.

Problem #4: Moving files from PC to SD card

Hello. I am having issues with my new Samsung Evo 64GB SD card. I had it for a few months and it worked just fine, then one night it just quit working.  I had over 40GB of music and photos that I was able to transfer off of it onto a computer, but the card was being acknowledged by my phone and then ready to be removed. After formatting the SD card multiple times, it was able to be read again by my phone.  Now the issue is with putting the files back on the SD card. Using the adapter it came with to make it a full SD and not a micro one, I plug it into my computer to transfer the files over.  As I begin, I get the mean?  I’ve tried using the usb cord and it doesn’t even copy a single file over in 5 minutes.  Any help would be greatly appreciated as this has been more that frustrating.

Thanks. — Andrew

Solution: Hi Andrew. Please contact us again and kindly explain in detail what you’re trying to say. We can’t seem to understand your point at this time.

If you need help assistance in moving data between your S7 and PC, or vice versa, kindly use a guide we’ve written for Note 5 users before. There may be some slight differences in features but the principles in this guide should still be the same with an S7.
