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

Problem 1: Galaxy S7 won’t charge

I’ve never had an issue with my Samsung Galaxy S7. I took the SIM card out of it as I now have a new phone and left it to the side. Once the battery died out I was unable to recharge it. I have checked the chargers and they work. When I put the phone on charge it heats up but no charging symbol appears. — Nila

Solution: Hi Nila. There’s a chance that the phone’s charging port may be malfunctioning. To check, try to wiggle the cord when charging to see if the phone will respond. Sometimes, a bad charging port is not completely disabled so wiggling the cord can elicit a response from the phone.

One good thing to try in this case is to see if wireless charging works. If it does, that eliminates the possibility that the battery or motherboard is bad. If you don’t have a wireless charger, try borrowing from a friend, or visit a shop that has one.

If the phone remains unresponsive or won’t charge at all, send it in for repair.

Problem 2: Galaxy S7 only charges until 77%, battery drains fast

Hello. My Galaxy S7 won’t hold a charge anymore. Not only that, it only charges to 77%. Once it hits 77%, it starts to go down even while on the charger. In 20 minutes my phone goes from 77 to 0. Even when I’m not using it. It started doing this 3 days ago. I tried a soft reset (I think) but that didn’t help me. I wanna try everything I can before I have to spend money to get it fixed if it’s fixable that is. — Melodyofelixirs

Solution: Hi Melodyofelixirs. Make sure that you recalibrate the battery. This will help Android detect the actual battery levels. It can be done easily. Here’s how:

  1. Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
  2. Charge the phone without turning it back on.
  3. Wait until the battery says it is fully charged to 100%.
  4. Wait for an hour before unplugging the phone from the charger.
  5. Use the phone until battery reaches 0% percent. The phone should turn off by itself.
  6. Recharge the phone to 100%, wait for an hour before unplugging it again.
  7. The battery should now be recalibrated. Observe how phone works.

Should battery recalibration won’t work, make sure that you restore all software settings to defaults. Here are the steps:

  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 3: Galaxy S7 Google Voice keeps turning itself on and off, keypad won’t work

I have a Samsung Galaxy S7 and I recently updated my phone after a long waiting of delaying. After updating, I’ve been experience some aggravating problems such as not being able to open my phone keypad, contacts, or message, as well Google voice constantly turns it self on with no initiation that I am aware of. Is there any way to fix these problems? — Melissa

Solution: Hi Melissa. If you haven’t tried a cache partition wipe, make sure to try it first. This will ensure that the phone is using a good system cache. Sometimes, updates and app installations can corrupt the system cache, resulting to issues that can range from minor bugs to major glitches. To wipe the cache partition, follow these steps:

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

Another good way to minimize problems right after an update (and one that is often overlooked by a lot of Android users) is to ensure that all apps are up-to-date. Make sure to open Google Play Store app and update everything from there, especially if you turned off the default setting enabling automatic app updates.

Also, you want to see to it that all your apps are compatible. Most of the time, it’s tricky to know for sure if an app is compatible with a new operating system or not but these are some of the helpful ways to know that:

  1. Visit the download page of each app in the Play Store and check the reviews of other users.
  2. You can also check the information provided by developers about the app. Responsible developers are likely to indicate that their product may not work with certain Android version or phone model.
  3. Do some digging if an app was created by an unknown or untrustworthy developer. Keep in mind that malware in Android are spread via apps. If you are not careful when installing apps, you may compromise your device. Some nefarious developers will initially allow you to install a legitimate app but later on, after an update, such app may switch to its malicious form.

If nothing will change after doing everything above, do a factory reset. Refer to the steps above.

Problem 4: Galaxy S7 music won’t play clearly when using headphones

Music plays but it won’t play loud enough for me to hear with headphones on. I can hear the beat but not the words. I changed the equalizer and the other one but nothing helps. I don’t know which version I have it updated so I don’t know which one it is. — Kiesha

Solution: Hi Kiesha. By the “other one” we assume that you’re referring to Adopt sound option under Settings>Sound and vibration>Sound quality and effects. If you’re absolutely sure that you set the Equalizer and Adopt sound options properly, then try to focus your troubleshooting to the headset. Try using another known working headset to see if the current one is defective.

We don’t think there’s an issue with your music app but just to be sure, try playing the songs while on speaker to know if the words are really garbled or muffled.

Finally, if the problem remains after using a second headset, wipe the phone clean with factory reset.

Problem 5: Galaxy S7 black screen issue, LED light turning on

Hello. My phone has just gone blank since yesterday evening. Doesn’t show charge sign while plugging for charge but only LED Light is on. I have tried to remove the SIM card and insert back with no success. I can not switch it on at all. It is Samsung S7 Edge with 1year and few month time. — Eddyray87

Solution: Hi Eddyray87. If the LED light is lit, that means that your phone actually turns on but the screen doesn’t. That also means that there may be a display problem. Samsung Galaxy screens are top quality products and they usually fail only if a phone is dropped, physically impacted, or exposed to elements like water or temperature extremes (hot and cold). If any of these things happened on your device, stop whatever you’re trying to find and just send the device in.

However, if your phone was never physically damaged and the problem just happened all of a sudden, this may be caused by an unknown Android glitch. Try to boot the phone to Recovery mode and see if it works. Here’s how:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. You can either wipe the cache partition or do a factory reset when in this mode.

If the screen works again after performing the hardware button combinations and when in recovery mode, that means that the problem is most probably operating system related. Recovery mode is a separate software environment independent of the operating system so it shouldn’t be affected by whatever bug coming from Android. In that case, you must perform the steps below on how to factory reset your S7:

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

Problem 6: Some Galaxy S7 photos are corrupted

Some of my pictures have disappeared (see screen shot). When I click on the “details” icon on the grey screen, I get all of the info of where the picture was taken and when etc so the picture is still there somewhere but it just won’t show. I am unable to backup. I have tried a soft reset and clearing the gallery cache but it has not helped. — Priscilla_law

Solution: Hi Priscilla_law. The photo icon with an exclamation point is an indication that your phone is unable to render or display the image properly. In other words, those files are gone or have been corrupted. Their metadata (details) may still be there but your device can no longer show the photos because the file integrity may be damaged for some reason. Try to move those files to your computer and see if a PC or Mac can still display them properly. If a computer can’t, those files are good as gone.

Problem 7: Galaxy S7 has missing portrait and landscape mode option

Hi there. I have a question about my Samsung Galaxy S7 Edge. My phone recently updated and it no longer has the screen rotate feature. Is there a way to reinstall this feature onto my phone? Thank you for your help. — Ljuba

Solution: Hi Ljuba. What exactly do you mean by screen rotate feature? Are you referring to portrait and landscape mode? If you are, that icon can easily be accessed in the status bar. When in Home screen, simply pull the status bar down and look for the icon that looks like a box with a padlock inside it. If you can see that, that means that your screen is currently locked in portrait mode. To view the screen in landscape mode, simply tap the portrait icon so it will change into a diamond with two curved arrows in the side.

Problem 8: Galaxy S7 restarts on its own

I have a Samsung Galaxy S7. From this morning my phone keeps turning on then turns off after 2 minutes and it’s been doing that for the whole day. I can’t do much within those two minutes as apps will not open. I have tried turning my phone off for a while but it made no difference. What should I do? — Priya

Solution: Hi Priya. Your situation is what we call random reboot issue. This issue can be caused by either a software glitch, an app bug, or a bad hardware. Try connecting the phone to a charger to see if that will stabilize the device. If it does, that means that you may have a problem with either the battery or the power management IC. Both require a repair so be sure to contact Samsung or an independent service center so your phone will be checked.

If your phone won’t stabilize even when plugged in to the charger, do a factory reset to see if it’s an app or operating system issue. We suggest that you first boot to Recovery Mode (steps given above) and do a factory reset from there. If the phone continues to boot on its own in Recovery mode or after a factory reset, it needs repair.

Problem 9: Default storage location of photos in Galaxy S7

I want to know “where” to find the number of photos I have taken. Under My Files, DCIM, images there are 1,000 of photos but no number of photos (I.e., 4,367). I copied photos to USB but wish to know if all we’re copied before deleting from phone. Thank you. — Mauiboy9999

Solution: Hi Mauiboy9999. The default path where photos taken is stored is this: My Files>Internal Storage>DCIM. If you want to know how many items a folder holds, simply tap and hold one item and wait until the items counter at the top left appears. Once you select All you’ll see the number of items are in that list.

Problem 10: Galaxy S7 won’t install update

Hi. I have got phone which i brought from Gumtree. im tryin to update the phone to the latest update but my phone is not updating. I have rang Samsung UK but they said they can’t help. How would i update my phone? Many thanks. — Rob        

Solution: Hi Rob. You’ll be unable to receive an update your phone over-the-air (OTA) if it was not built for the carrier you’re on right now. That’s because carriers only release an update for phones built for their system. If you badly need to update the phone, you can try to install Samsung Smart Switch to your computer, connect your phone to the computer with USB and see if there’s an available update for it.

If update via Smart Switch is not available, you can try to manually update the device via flashing. Keep in mind though that flashing is a risky procedure and may be a bit overwhelming for average Android users. If you want to flash or install the update yourself, make sure to do research about the subject. One wrong step and you can potentially brick your phone. You want to ensure that you know what you’re doing.

Problem 11: Galaxy S7 won’t recognize SIM, keeps saying battery cover is closed

My Samsung Galaxy S7 will not recognize that the SIM card is in and along with that it keeps telling me to make sure the battery cover is closed. It is also restarting on its own every few minutes and the battery is draining fast. I contacted my service provider and they are sending a new SIM card but I feel like it has more issues than that. The phone is only 4 months old and I’ve always had an otter box on it, so it has been protected. — Robyn

Solution: Hi Robyn. Your phone has an unremovable battery pack so getting a notification about battery cover not being closed is off. This can be an Android glitch so make sure that you factory reset and observe the phone when there are no apps installed. If that message continues despite the factory reset, you should demand a new phone from your service provider.
