Problem #1: How to recover possibly corrupted files from SD card in a Galaxy S7

Gallery pictures replaced with grey. I removed SD card yesterday and downloaded images. All seemed to be present. Videos not playing but that may be due to old PC (Windows Vista). I did a power/volume down button reboot. Some pictures on the phone have returned but majority remain as grey thumbnail. Incidentally my PC today will not turn on. Making intermittent fan noise no screen. Could be a coincidence. Do you have any suggestions as to how i could retrieve my images in the gallery? I do not know which Android version the phone has. Kind regards. — Carly

Solution: Hi Carly. The process of recovering files from a storage medium can sometimes be tricky and may require advanced software. If the greyed out files have been corrupted, even advanced software may not be able to recover them at all. The easiest way to see if you can recover files from a Galaxy smartphone is by connecting it to a PC. So yes, you must need to have a good working PC first in order to see if another device (computer) can read those files. If a Windows or Mac machine cannot read the files anymore, try looking for third party services online that can help you recover them. Our blog does not have offer file recovery services so use Google to search for good ones. These services are not free and there’s no guarantee if their software will work. But then again, as we’ve said, file recovery process itself is full of uncertainties. If a third party software won’t be able to read the storage device in the first place (because there’s a chance it’s been corrupted), you may have to simply accept the fact that those files are gone.

Problem #2: Pre-owned Galaxy S7 keyboard app constantly lagging | Second-hand Galaxy S7 keeps freezing

I recently bought a second hand Samsung Galaxy S7. Upon buying I noticed that the phone’s keyboard was constantly lagging, very slow and did not type the letters I touched. I tested the touch screen using the code *#7354# and found out that there wasn’t anything wrong with the touch screen of the phone so that wasn’t the issue.

The S7 also freezes up and the only thing that can unfreeze it is holding the low volume button and the power button simultaneously.

Also the phone frequently restarts itself randomly. I have tried codes, resetting, rebooting, restarting, I have cleared the cache partition and finally updated the phone to Android 6.0.1 and still nothing has changed. Please help ASAP. — Sabah

Solution: Hi Sabah. Buying a pre-owned electronics is always risky, especially if you don’t personally know the seller. Since you did accept the risks involved, you must be ready to accept the consequences of your action. There’s always a chance that you can inherit a problem that may be unfixable at your level. If you can still return the phone at this time though, we strongly suggest that you do so to avoid heartaches in the future. The combination of being a second-hand device and having multiple seemingly unrelated issues right off the bat is definitely not a good sign of a properly working phone. The issues you mention may be indicators of a hardware issue that the original owner was not able to address. The only suggestion that we have for you is factory reset. If the same issues remain even after a factory reset and without apps, there must be a problem with the hardware department.

Problem #3: SD card causing Galaxy S7 Edge to freeze

Hello. I tried to find my problem in the troubleshooting page but i was terrified when i didn’t find anyone complaining about the same issue! My problem isn’t an app or 3rd party app. It happens when i mount my SD card — it’s a 125GB original Samsung memory card that came with the S7 edge. And i only used 50 to 60GBs from it. It worked fine for 6 months but suddenly now it causes my s7 edge to freeze. When i mount the SD card, it acts normal for about 30 to 60 seconds, then it suddenly freezes. It doesn’t restart on its own and becomes totally useless and not responsive. All i can do is force restarting it by holding Power + home + volume down for 10 seconds. And then it happens again and again and again. After 30 to 60 seconds, the issue stops when i unmount the SD card!

Oh i would like to mention something that might be important too. A week ago or maybe 10 days, i had a ~35 Mb software update.

What should i do? Please help. — Riyad

Solution: Hi Riyad. If your S7 works normally when the SD card is unmounted or perhaps when physically disconnected, then that’s a clear sign that you must do something about the SD card. These are the steps that you must do:

  1. If you keep irreplaceable files in your SD card, make sure that you copy them to another device like a computer to avoid data loss.
  2. Once you’ve move important stuff to a computer or cloud, or another smartphone, the next step is to reformat the card. Here’s how:
    1. From the Home screen, tap the Apps icon.
    2. Find Settings and tap on it.
    3. Scroll to and tap Storage.
    4. Now tap on SD card.
    5. You are given two options; to ‘Unmount’ it or ‘Format’ it. Choose the latter.
    6. The phone will warn you that you will lose all files inside your SD card if you continue the process but since you still don’t have anything in it yet, it’s safe to continue. So, hit Format in the bottom-right corner.
    7. Wait until the formatting process completes.
  3. Now that the SD card has been reformatted, you also want to make sure that the phone’s system cache is refreshed. This is done by wiping the cache partition. Follow the steps below on what to do:
    1. Turn off the device.
    2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
    3. When the device logo screen displays, release only the Power key
    4. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
    5. Press the Volume down key several times key to highlight ‘wipe cache partition.’
    6. Press the Power key to select.
    7. Press the Volume down key to highlight ‘yes’ an press the Power key to select.
    8. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
    9. Press the Power key to restart the device.
  4. Observe how the phone works afterwards. Make sure that you restart your S7.

Keep in mind that even original SD cards can fail anytime. To avoid losing important files in the future, make it a habit to create a backup of important files in another device all the time.

Problem #4: Pop ups keep showing on Galaxy S7

Phone keeps getting pop-ups. Even when trying to message. I mean a TON of pop ups. Did factory reset twice. Did not help one bit. Sent it in under warranty to be looked at. They can’t replicate the issue. Returned phone unfixed. Since the return, 36 pop ups in one week. Can’t send text, takes 10 minutes to send ONE. Don’t get pictures. Just a gray square with exclamation point. Got a lemon. Don’t know where to return it to get a new one. Samsung or AT&T. HATE this phone! — Pam

Solution: Hi Pam. Pop ups that show advertisements are usually brought about by bad apps or malware. To fix the issue, you can do the following:

Scan your device with an antivirus app. This must be the first thing that you should do if you haven’t done it yet. With a lot of free antivirus apps available for download, every Android user must be doing this step all the time. Just make sure not to overdo it by installing more than one antivirus in your phone as doing so can lead to a problem than resolve one.

You must know though that some recent or advanced malware be able to get through most antivirus apps, so if no antivirus can help you stop the pop ups, proceed to the next step.

Boot the phone in safe mode. If the pop ups started showing up after you’ve installed an app, chances are that app comes from a suspicious developer. In order to check if these pop ups are caused by third part apps, try to boot the phone in safe mode. If the phone works normally and no pop ups show, that’s a confirmation of our hunch. Your next move then is to uninstall apps individually until you have eliminated the offending app. Safe mode won’t pinpoint the bad app so you must do trial-and-error to identify it. That’s done by observing the phone after every uninstallation. But first you must boot in safe mode. Here’s how to do that:

  • Turn off the phone completely.
  • Press and hold the Power key.
  • Once ‘Samsung Galaxy Note5’ shows, release the Power key and immediately press and hold the Volume Down button.
  • The phone will restart but keep the Volume Down button pressed.
  • Once the phone has finished restarting, ‘Safe mode’ will be display in the lower-left corner of the screen.
  • You may now release the Volume Down button.
  • Observe the phone for 24 hours to see the difference. Remember, if the issues you mention here won’t happen when safe mode is enabled, one of the third party apps must be to blame. In this case, you need to uninstall apps until the problems are eliminated. Safe mode won’t help you pinpoint the actual offending app so you must do trial-and-error in identifying it. The most effective way is to uninstall apps individually then observing how the phone behaves afterwards.

Factory reset your phone. Restoring all software settings to their known working state via factory reset is the most effective way to get rid of a virus or malware from an Android device. Refer to the steps above on how to do it. Make sure that you observe how the phone behaves after a factory reset. Here are the steps on how to factory reset your device:

  • 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.

Do not install app outside of Google Play Store. After a factory reset, ensure that you don’t just re-install the same set of apps. Many Android users tend to do this, rendering factory reset procedure useless. Installing the same apps after a factory reset will just re-introduce the problems. Try to install apps individually so you can observe how the phone works afterwards — install an app, observe, install and app, observe. Doing this cycle will take some time but it’s the most effective way to get rid of bad apps. Also, make sure that you check if an app has lots of positive reviews. Visit its Google Play Store page and check if there are many positive reviews about it. This will give you an idea whether or not an app can be trusted or not. If you notice that a lot of users mention getting pop ups after installing this app, you may have found the reason for your woes.

More importantly, try to avoid installing apps from sources other than Google Play Store. Only install apps from third party sources if you are 100% sure that they are harmless. Keep in mind that most of the Android malware that were recently discovered were introduced via these third party sources. If you  want to break this rule, do it at your own risk and be ready to face the consequences.

Problem #5: T-Mobile Galaxy S7 stock messaging app and Handcent not working

I have a Galaxy S7 with T-Mobile, and had used Handcent SMS with my old phone – loved it. Now on my S7 everything is screwed up. I thought it was Handcent (none of their updates helped), but am now having the same issue on the native messaging app. If I create a new message to one contact, it will send out and then appear as part of an old group message including other contacts. I go back into that specific message and there is no way to create or respond to the message and I’m not sure if my message went to all of the recipients or just the one I sent it to. This issue is driving me nuts, even deleting strings and then creating a new message to a single contact does the same thing. I’ve searched high and low on message boards and I must not be using the correct terminology because I can’t find the issue. Please help! Thanks. — Allison

Solution: Hi Allison. If the problem occurs to both pre-installed app and third party app, it’s highly possible that the issue is on the firmware level. Try doing a  factory reset then observe the phone for 24 hours (without apps) to see the difference.

Problem #6: Galaxy S7 won’t boot normally

Hello. I have an S7 running Android 6.0. I’ve been using it for 2 1/2 months and everything was smooth. However yesterday, I was on a normal cellular call with the Wi-Fi running in the background and around 20% of battery left. Phone turned off all of a sudden. It wouldn’t turn back on. When I charged it, the led indicator was not working.

I wasn’t sure if the phone was even charging at all, so I used the original charger on my sister’s phone and it was working. plus I used a power bank on my phone and the power bank’s led was blinking which means it recognized that my device was plugged to it. After charging it with my power bank for a while I pressed the volume up + volume down + power buttons all at once and kept at it. I felt a vibration but nothing else. Left the phone charging for another two hours then tried again, and this time ( and some other times afterwards ) the Samsung logo appeared on my screen as it usually does when I open my phone normally, but this time nothing happened afterwards. It just turned off after 5-10 seconds, and again no led indicator when I charged the phone and it wouldn’t power on. Battery, of course, is non-removable. Can you please help me? Thank you in advance. — Babis

Solution: Hi Babis. The very first thing that you want to try right now is to check if your phone will still boot to other modes. If it can, you may be able to bring it back to life after doing a specific procedure depending on what mode the phone decides to boot on. Here are the boot modes you can try:

Boot in Recovery mode:

  • Charge the phone for at least 30 minutes.
  • 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.’
  • You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  • Charge the phone for at least 30 minutes.
  • Press and then hold the Home and Volume DOWN 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 DOWN keys.
  • Wait until the Download screen appears.
  • If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  • Use Google to look for a guide on how to do it.

Boot in safe mode:

  • Charge the phone for at least 30 minutes.
  • Press and hold the Power button.
  • Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  • Continue holding the button until the phone finishes rebooting.
  • Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  • The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

If the phone remains totally unresponsive and won’t boot to any of these modes, find a way to have it repaired or replaced.
