Below are specific topics we’re bringing for you today:

Problem 1: Galaxy S7 can’t read encrypted SD card

The phone isn’t reading my encrypted Micro SD card. I was using it normally and then I tried to open a picture in the Gallery and the album wasn’t there. At first I thought I was in a different root but then I realized that the phone wasn’t reading and opening the information in the SD. I turned off the phone, removed the Micro SD and mounted on my laptop. I was so happy to see all my albums and files in the SD. I tried to open any file BUT surprise, my info is encrypted. I return the SD to the phone, turn it on but nothing. If I go to the security menu on my phone / Encrypt SD card, I have the 2 options: decrypt and encrypt. If I try to decrypt the card, the process start searching and then crash. So? What can I do? I can’t format the card, but I can’t format the phone either so what’s wrong? — Juan Pablo

Solution: Hi Juan Pablo. We have no way of telling what exactly is wrong why you have this situation. All we can do is speculate but unfortunately, that won’t fix your issue at all. To be honest, there’s really nothing much that you can do. Perhaps, a software glitch hit something that changed some operating system configuration. Again, we can’t be so sure about that. Doing device troubleshooting like factory reset is a big no-no so that leaves you with SD card reformat option, which obviously deletes all your data. Inserting your SD card in another phone is definitely out of the question.

We are not aware of any effective third party recovery tool out there but if you think your data is worth a few hundred dollars of investment, consider using the services of companies that specializes in data recovery. There’s no guarantee that they can successfully access your files so be ready to part ways with your money if that happens.

Try using Google to look for reputable companies that can help you. Be sure to let them know of the entire situation so they can give you advise before paying up.

Problem 2: Galaxy S7 won’t turn back on after used under water

I took underwater photos with my Galaxy S7 phone (it was under water for about 3 or 4 seconds and it was just 3cm under the water). I don’t know if that matters but it happened in Greece and the water has much salt in it. After I went out of the sea I noticed that the phone doesn’t work correctly and doesn’t accept my commands. I put it next to me in order for the sun to dry it. It didn’t work so I got home and wrapped it in a towel and waited for about an hour and it didn’t start to work. After all, I decided to leave it on the shelf with the SD card out of it because there was nothing left that I could do in that situation. We are on a vacation and I can’t take it to a technician. Can you please tell me if I can do anything else because after everything I have done the display still doesn’t work. I also restarted it from the power and the volume down buttons two times because it can’t shut down. It just doesn’t accept any of the commands I try to give it. I’ll be very thankful if you give me any advise for that problem. — Elizabeth

Solution: Hi Elizabeth. Although a Galaxy S7 is rated as water-resistant, it’s not fully water proof. Dunking it in free flowing water might still damage it and we’ve already seen a lot of such cases before. Not exactly a confidence builder for an expensive device marketed as almost water proof.

Anyway, if your phone is dead and doesn’t respond to any hardware button combination at this time, there’s nothing much that you can do. The best thing that you can do right now is to wait until you get home so you can send it to Samsung. The hardware must be checked so it can be assessed if repair can fix it.

Problem 3: How to customize notification settings in Galaxy S7

I just got the Galaxy S7. Yesterday, when my screen was locked/black, it showed the date, time and battery level as well as any notifications from messaging and emails. Today the messaging and emails don’t show up. How do I get that back?

Also, I don’t like that when a text come and I unlock the screen the text is showing up in a large box in the middle of the screen. Is there a way to change that? — Emily

Solution: Hi Emily. To fix these issues, you must customize how each app shows notifications. Below are the steps on what you need to do:

  1. Open the Settings app.
  2. Tap Notifications.
  3. Look for the app you want to turn notifications for and tap it. This will turn on notifications for this app.
  4. Tap ADVANCED at the upper right hand side.
  5. Select the app you want to set the notifications for.
  6. Select the setting you want. The explanation for each option should be easy to understand.

Problem 4: Galaxy S7 drains battery power faster when using AT&T SIM card

I’ve had my Samsung Galaxy S7 for over a year with T-Mobile as my carrier. Soon I will be moving from California to Iowa. The location in Iowa has no T-Mobile coverage, so prior to moving, I have decided to switch carriers to AT&T. Herein lies my problem. I used to get upwards of 24 hours on a full battery charge. The very moment I switched to AT&T, I noticed a serious and rapid drain on my battery and I can literally watch the % go down. I am lucky to get 3-4 hours now, and have it constantly attached to my portable charger.

I have not changed anything on my phone, no updates, no new apps, no settings adjustments. The ONLY thing I did was replace my T-Mobile SIM card with the new AT&T SIM card and that is all.

Of course, the AT&T reps deny that my battery issues are caused by their towers or switches, and instead, suggest I buy a new phone (or battery at the very least). I checked Battery Usage and I show only a couple of apps using less than 3%. Nothing out of the ordinary. Any help would be greatly appreciated. Thanks. — Ray

Solution: Hi Ray.  We can’t think of any logical explanation for the problem other than the possibility that your phone may be working harder to establish good connection to AT&T network compared to when it was still in its mother network (T-Mobile). Keep in mind that your phone is still running the T-Mobile firmware. This means that everything on it has been validated to work efficiently with T-Mobile system. Now that your still running a T-Mobile software but using the network settings of AT&T, some things must have changed, causing the device to spend more battery or processing power. We can’t be sure of this for sure but since you’re positive that the only change you’ve done is to use an AT&T SIM, this is the most likely explanation. Try to factory reset the device and see how it works. If that won’t solve your issue, you just have to accept the situation.

Below are the steps on how to factory reset your S7:

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  2. Turn off your Samsung Galaxy S7.
  3. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  4. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  5. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  6. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  7. Once highlighted, you may press the Power key to select it.
  8. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  9. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  10. The phone will now reboot longer than usual.

Problem 5: Wet Galaxy S6 won’t power back on

Hello. So, my Galaxy S6 got wet. Not submerged. Just wet. My daughter splashed water on it from her bath (it was sitting on the bathroom floor) and I didn’t notice until about 10 minutes later. I took it out of the case and wiped the water off. It appeared to be fine. Then the touch screen stopped working. The phone is still on (at least until the batter dies) and because the touch screen isn’t working, I cannot turn it off. It doesn’t have a removable back either, so I don’t know how to go about taking it apart further to let it dry out. It is sitting in a bag of rice right now (dumb, I know, but what else can I do?) and before I put it in, the power button on the right side of the phone had also stopped working. What should I do? Can I take it somewhere? It is a Straight Talk phone. — Cailtinjmichael

Solution: Hi Cailtinjmichael. Unlike the Galaxy S7 and S8, your S6 does not have water resistance protection so even a splash can hurt it bad. Putting your phone in a bag of rice won’t do much at this time. Bring the phone to Samsung or an independent service center so the hardware can be checked. A professional also needs to check the hardware so it can be assessed if a repair will likely fix it or not.

Problem 6: Galaxy S7 won’t charge, won’t turn on

I have a Galaxy S7. Yesterday it froze and it won’t reboot at all. When I plug it into the wall, it shows a battery with a lightning bolt but it doesn’t fill up green showing it’s got charge. I have tried all the possible reboot fixes by holding in the power key and volume keys ETC but none of which have fixed the phones issue. I’ve looked all over the net but nothing seems to give me the right advice. — Kailadobson58

Solution: Hi Kailadobson58. The tips and possible solutions that you’ll find online are mostly intended to fix software causes of this problem. If your phone no longer boots up right now, that means that you can’t perform any of the suggested software tricks that you’ll find. It also means that bad hardware is the mostly cause of your problem.

Try to charge the phone with a different charger and USB cable and see if that will work. If you have a wireless charger, you can also try that to see if the problem lies in your phone’s charging port.

If you can’t power the phone back on using any of these means, have it repaired or replaced.

Problem 7: Accidentally dropped Galaxy S7 has cracked screen

I dropped my phone and there is a small superficial crack on the bottom by the home button. If I hit the power button, my screen goes black; it stays on. I can hear the pages opening or the volume buttons. Everything is responsive except the screen. it will blink and if I mess with it for a couple hours I can get it to light up. But I can’t let the display go dark or time out. Cuzco I’m screwed. — Jennifer

Solution: Hi Jennifer. If you want to fix the problem, you should stop looking for any software solution. There’s no amount of software tweak that can be done to fix a damaged hardware. Contact Samsung and have the device repaired or replaced. If your phone was part of your subscription plan, contact your carrier so it can be replaced.

Problem 8: Galaxy S7 apps keep crashing after installing Android Nougat

Hi. I recently updated my phone to Android version 7.0 and it is a nightmare. The most important issue is that I can’t view my messages or text on the system’s messaging app. When I tap to open… it immediately shows this message on my screen: “ has stopped” or “ keeps stopping”. Please help me what can I do to fix this problem? Many thanks, Sabrina P.s. if possible I’d like to avoid doing a factory reset. Thanks. — Sabrina

Solution: Hi Sabrina. The first possible solution to your problem is cache partition wipe. Do that and observe how your phone works for some time.

If the problem returns, make sure that all your apps are up-to-date and compatible with the current operating system. Even if the specific app you’re having problem with is okay, it’s possible that one of your apps is affecting the working ones. Go over your list of apps under Google Play Store app and make sure to check each one if it’s compatible with Nougat (Android 7.0). You can also observe how your phone works when it’s on safe mode. This will help you tell if one of the third party apps is to blame or not.

Below are the steps on how to restart your S7 to safe mode:

  1. Turn your Galaxy S7 off.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.

If nothing changes even when your phone is safe mode, do a factory reset.

Problem 9: Galaxy S7 screen flashes green, screen won’t turn on right away after a restart

So, I have an S7. I began to notice something. Every now and then, when I turn off my screen, it would flash green, then turn off and when I try to turn it on again, it doesn’t turn on after I try for a few minutes.

Also, whenever I leave it in a cold environment, the same thing tends to happen. I tried asking somebody about it and they said it might be because I dropped it. I’m not sure if that is the case so that’s why I’m asking here before I pay for a repair. Hope you can reply, and thanks. — Cedric

Solution: Hi Cedric. Most issues about erratic or discoloration of the screen are caused by hardware malfunction. If you did dropped the phone badly before, that may have damaged something in the motherboard though it’s only now that you’re seeing the negative effect. Like water damage, the unnecessary shock from an accidental drop can lead to anything. For some, issues can begin showing right away, while in some cases, much later.

To check if hardware issue is to blame, do a factory reset first and observe the phone for a day. During this time, try to replicate the issue by doing the things that you normally do when this issue occurs. If the issue won’t occur, a software glitch may be to blame. That’s good news since you can most likely fix it by removing a problematic app, installing an update, or flashing.

If the problem continues even after a factory reset (and without apps installed), you must have a hardware issue at hand. In this case, you should consider repair or phone replacement.

Problem 10: How to change the appearance of Galaxy S7 after updating to Android Nougat

Hi guys. It’s not so much a glitch but everything seems dull and boring in the update. When I get emails, there is no colour to differentiate new emails from old ones and all the writing is the same size, nothing stands out. In the notification window the writing is like outlined as opposed to the writing being filled in like, it’s kinda ghost writing. It’s horrible. Can I change the text on everything? — Davedave1973

Solution: Hi Davedave1973. If you don’t like how the new update changed the previous look, there are a number of options that you can try.

Firstly, you can try to download a new font to replace the existing set of fonts. You can change the font, font style, and font size by going under Settings>Display>Screen zoom and font.

If changing the font won’t be enough, you can also try to change the look of some aspects of the phone by using a different theme. Just go under Settings>Wallpapers and themes.

Finally, you can also change the overall look of the phone by using third party launchers. Try to take a look at this link and visit a website that lists some of the popular Android launchers nowadays.

  1. The mic won’t stay open long enough for me to speak after last system upgrade on my Samsung Galaxy S7. As soon as I touch it, it appears to go into listening mode but immediately goes back to the app screen.
