Problem #1: Galaxy S5 won’t charge

I have a Samsung Galaxy S5 and it stopped charging a couple days ago saying that i need the original charger. i had the original charger plugged into it later that night and it would only charge for like 15 minutes and then it would stop saying the same message. well now it has completely stopped charging and the screen doesn’t light up when i hold the power button, due to it being so dead. Today i tried to charge it via usb and my computer then got a notification saying that my phone is unrecognizable. And now i don’t know what it is because my computer detected it so it’s not that the USB port is dirty or damaged. i also did the spin test with my battery and it passed so i know it’s not a faulty battery. Very confused. please help. — A. Lee

Solution: Hi A. Lee. USB connectors, whether in female form (the USB port on your S5) or male form (the male form on your charger cable) have at least four contacts — one for ground, one for power, and two lines for data. The Galaxy S5 uses the USB 3.0 standard, which means that it has more than four contacts. Although we can’t really know where the problem lies in your case, we believe that it may be the power connector that transmits current to and from the device. There’s no need to actually speculate on this one since it won’t help fix the issue a bit. There’s no other trick that you can do to make the device charge again. The best thing that you can do is to recognize that the S5 does not charge anymore and that the hardware must be checked. Contact Samsung or your carrier for repair or replacement.

Problem #2: SD cards inserted in Galaxy S5 keep getting corrupted

I installed the PIXMA photo editing app on my Galaxy S5 & played with it a bit. The next morning, the phone didn’t show any micro SD card photos (as if it wasn’t even there). When I searched the phone, it told me the SD card was corrupted. I powered down & removed it, put it back in, still nothing. I tried to look at the SD card on my laptop & no-go. Took to the Verizon store — no access. Removed PIXMA from my phone. Got a new micro SD for my phone. Took many photos & videos. Periodically noticed when I opened the SD photo file, some of the pictures would be 1/2, 3/4, or entirely grey…like they were being erased. When I tried to load all photos onto my computer (via adapter in SD port on laptop), they wouldn’t load. Tried taking to a Walgreens machine, it would load about 1/2 of the photos & videos & then tell me to reinsert the SD card (as if I’d removed it). The photo tech said there must be corrupt files. I was finally able to load most photos to the laptop via Bluetooth, but certain files simply wouldn’t transfer. — Julie Ann

Solution: Hi Julie Ann. If some files can’t be transferred to your laptop, I guess you already know our answer — they must be corrupted. There’s nothing that you or we can do about that. The only thing that you can do starting now is to prevent this issue from happening again. To do that, try checking some suggestions below.

Factory reset the device. We can’t know what causes your SD card to get corrupted as there are many factors to consider so you have to make sure that it’s not the software. This can be done by wiping the phone clean first. Hopefully, factory reset will eliminate the glitch and prevent it from developing again in the future. For instructions on how to factory reset your S5, follow these steps:

  • Turn off the device.
  • Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  • When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  • When the Android System Recovery screen appears, release the Volume Up and Home keys.
  • Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  • Press Power button to select.
  • Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  • Press Power button to select and start the master reset.
  • When the master reset is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.


Reformat the SD card. Once you’ve factory reset your S5, the next best thing to do is reformat the SD card. This will ensure that both the S5 and the SD card start fresh. Make sure that you use the S5 to reformat the SD card.


Never interrupt the device when it’s reading or saving something on the SD card. One of the most common reasons why SD cards get corrupted is due to human error. Sometimes, it can take longer for a device to load something from an SD card and our impatience can make us do something stupid. Keep in mind that some apps can be stored in an SD card so loading some them or their associated files and services may take longer to load. The same is true when a device tries to write something to an SD card, like when it’s saving a video or photos, or documents. Make sure that you wait until the process is done before attempting to do anything on the phone. Doing otherwise almost always lead to SD card problems.


Avoid encryption. Although it’s good practice to secure important or critical data, doing so for almost everything may backfire for you. Encryption can significantly degrade a device’s performance because it will have to do more processes in the background. If you really want to safe guard some important files in your phone, you must contend with slow performance when your device loads or saves something. In some rare cases, encrypted SD cards also get corrupted for some reason.

Problem #3: Cannot allow permissions for apps on Galaxy S5

Hello. I can’t seem to allow permission on my applications. I had already reset my phone before due to this problem but it’s still the same. For example, I wanted to send my sister a photograph then the box appeared asking me if i want to allow my gallery to sync with messenger. When i clicked on allow it asked me to turn off the screenover which i did but it still is not working. I even went to application manager and tried to allow permission from there but the problem is still the same. Please help me. It’s kind of frustrating that any application i install and try to open the same is happening. I hope you can help me. Thanks. — Asmita

Solution: Hi Asmita. We’re not sure if we understand your situation correctly. Permissions are usually set during app installation and you’re not supposed to tinker with them afterwards to prevent apps from malfunctioning. Assuming you did not root your device or flash a custom ROM, you may be able to fix the issue by wiping the cache partition. Here’s how:

  • Turn the phone off.
  • Press and hold the following buttons together: Power, Volume Up and Home.
  • Release the buttons once the Android system recovery menu appears.
  • Use the Volume buttons to navigate to Wipe Cache Partition option.
  • Press the Power button to confirm selection.
  • Select Reboot System Now option after deleting the cache. Wait for the phone to reboot.

Should the issue remain after refreshing the system cache, make sure that you reset all software settings back to default by doing a factory reset. Refer to the steps above.

Problem #4: Galaxy S5 turns Wi-Fi on and off on its own

Samsung Galaxy S5. I just replaced with factory rebuild phone thru Verizon in June 2016 due to it freezing up during a software update. horrible experience. My new phone has started turning the wifi off on its own CONSTANTLY even though it is set to ‘keep wifi on during sleep’ in settings. The Bluetooth automatically turns on constantly. The wifi turning off is the biggest problem because I am constantly having to monitor it and turn it back on to not exceed my data plan. the Bluetooth turning itself on isn’t as big a deal except that it drains my battery faster. Any ideas on why this has happened?

I asked Verizon at our local customer service center and they are worthless…they don’t staff anyone with a tech 2 or 3 or higher on site. The rep told me she didn’t see a problem since I’m not exceeding my data plan yet!! Clueless. this is the same store that told me to go to best buy and see if the geek squad could help me with the software update freeze issue…even though I didn’t buy my phone from best buy. they weren’t pleased with that either. Ugh. — Jean

Solution: Hi Jean. In fixing Android problems, a simple guideline is followed by technicians like us — if solutions don’t work, then hardware must be to blame. With all sorts of apps readily available to be installed and the many different Android versions out there, there’s no surgical way to identify the cause of a particular problem like the one you’re having. The only thing that we can do is trial-and-error. That said, we suggest that you start with the basic wiping of the cache partition.

If that won’t help, boot the phone in safe mode for as long as you can (a few days is best) so you can observe how it goes. The main purpose of booting your phone to safe mode is to see if a third party app is the cause. While safe mode is enabled, all third party apps and services will be prevented from running. So, if the issue won’t occur during the observation period, you are right on the money. The only next thing to do is to uninstall third party apps until the cause of the issue is removed. To boot in safe mode, follow these steps:

  • Turn the device off.
  • Press and hold the Power key.
  • When ‘Samsung Galaxy S5’ appears on the screen, release the Power key.
  • Immediately after releasing the Power key, press and hold the Volume down key.
  • Continue to hold the Volume down key until the device finishes restarting.
  • Safe mode will display in the bottom left corner of the screen.
  • Release the Volume down key when you see Safe Mode.

Should nothing work, do a factory reset.

Finally, if factory reset won’t work either, you can assume that there’s a problem on the hardware department. Contact Samsung or your carrier for a unit replacement.

Problem #5: Galaxy S5 won’t connect to cellular network after charging port repair

Hi. I don’t have Data or Cell connection. I called the AT&T store and they made a connection with the phone and i saw a few bars and 4G but since then it has gone. I had my port repaired and it is charging and working right and good, but there is little or no connection to the tower. My Wifi is working very good and no problem. I have Factory resetted the phone and it is Samsung Galaxy S5 SM-G900A. It worked fine before i changed the port. What should fix this? or is it simple the SIM card not working, but then i would think that i woun’t ever get even a small connection? Thanks. I had the phone updated to the latest software. — Benjaminwurtz

Solution: Hi Benjaminwurtz. To check if it’s a SIM card issue, insert your current SIM card to another phone that supports AT&T connection. If the issue happens on the second phone, then find a way to have the SIM replaced. Otherwise, the problem must be your Galaxy S5 itself. Since it’s been repaired, there’s a chance the network chip that manages mobile data connection or an associated component that works together with the mobile data connection chip has been damaged. That factory reset did not change anything is an indicator that software is not to blame here. If you badly need mobile data connection, find a way to have the phone replaced; our blog does not provide hardware troubleshooting and solutions.

Problem #6: Galaxy S6 won’t accept PIN | Galaxy S5 “currently unable to download please try again later” error

Wondering if you could help please. My phone keeps showing me “Currently unable to download please try again later.” I was using fingerprint to lock and unlock it when I removed it and put PIN, the PIN refused to work. At the moment, it automatically started using a swipe and when I try to enter the PIN I use for the phone, it will tell me it is the wrong pin. Now I can’t use pin, I can’t use fingerprints. When I am cycling the phone unlocks itself in the pockets and sends messages and calls without my knowledge. — Obinna

Solution: Hi Obinna. The error message “Currently unable to download please try again later” is a generic one and does not really point us to a specific problem. Since you’re also having an issue with security on this device, we suggest that you restore the software settings back to default by doing a factory reset. Refer to the steps above.
