Problem #1: Wet Galaxy S5 screen remains black and won’t turn on

I dropped my Galaxy S5 in the toilet this morning by accident. The phone was on when it fell, the headphone jack end went in the water. It was not completely submerged; the battery port was not in the water. The phone seemed normal, as it was only in the water for MAYBE a few seconds. After about 5 minutes, phone flickered for a few seconds, and went black. I continued to get notification noises, and such, I pulled the battery, SIM and SD cards. Put phone in a bag of rice. (I did not put the battery in there as I have 3 batteries for the phone–if this battery is a loss I have 2 others). After being in the rice for several hours, the Samsung logo comes on when restarting, but then it is black again. Notifications and such also work. Since the logo was clear, that should mean that my screens are not completely ruined, correct? Is there anything else I can be doing? — Kellie

Solution: Hi Kellie. The only thing that you can do right now is submit the phone for a repair. Let a professional open the phone and clean the internal components. If you’re lucky, once the phone has been cleaned and dried up, you may be able to use it again normally. Keep in mind that water damage can lead to all sorts of issues. The main issue you’re facing now may be a bad screen assembly, but if some moisture remains inside, that could lead to corrosion of the motherboard, which can then lead to other problems. This is the main reason why a wet phone must be opened up, cleaned, and dried properly.

If you have the skill and tools to do the job, you may be able to find some websites that specializes in hardware troubleshooting and repair. Do some research using Google for guides on how to do it. Otherwise, just bring the phone to a repair shop.

Problem #2: Galaxy S5 won’t recognize SD card after rooting

My Galaxy S5 was working just fine until I rooted it. After I rooted my phone, it sometimes read my SD card. Every time it stops reading it, all I had to do was put my phone off and on. By the time it came back on, the problem was solved. Now all of a sudden my phone stop reading my SD card, so I try another SD to see if it was my SD card that was the problem. It turns out that it was my phone that was the problem because it was unable to read any memory card and all the memory card I used on it was working perfectly.

Now I unrooted my phone to see if that was the solution but to my disappointment it was not. My phone sometimes shows that the SD card is present but when I try and send something on the SD card, the SD card disappears.

Also my phone shows unsupported SD card and ask for me to format it and when I do it say SD card is ready to be removed but when I take it out and put it back in the phone does not read the memory card. Can anyone help me because I don’t want to bring my phone to the repair shop and then the same problem start happening again. — Biggbram

Solution: Hi Biggbram. We don’t know the full history of the device so we can’t say if this is an isolated issue, or whether it’s due to a bad rooting software or app. Try wiping the cache partition first to see if that will make any difference. Here’s how:

    1. Turn off the device.
    2. Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
    3. When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
    4. When the Android System Recovery screen appears, release the Volume Up and Home keys.
    5. Press the Volume Down key to highlight ‘wipe cache partition.’
    6. Press the Power key to select.
    7. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
    8. Press the Power key to restart the device.

Should nothing change after refreshing the system cache, try to observe the phone in safe mode. Safe mode blocks third party apps and services  from running so if the issue won’t occur, that’s means that one of the installed apps is probably causing a conflict with the operating system, resulting to this problem. Here are the steps on how to boot your S5 to safe mode:

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

Finally, if nothing changes after booting to safe mode, the last thing that may fix the problem is factor reset. Here’s how you do it:

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

An issue like this can also be caused by a bad SD card slot. If factory reset won’t help at all, have the phone repaired or replaced.

Problem #3: Galaxy S5 won’t charge

Hi. My Samsung S5 randomly wouldn’t charge the other day. I took out the battery and held down the power key for 1 minute then put the battery back in, and while turned off it charged very slowly (but very glitchy, sometimes it didnt work). That worked (sort of) for a few days but now it won’t even charge while turned off. If i plug it in while turned off, the battery bolt symbol will show up for about 10 seconds, then it will disappear and the caution sign (or whatever it’s called) will appear.

I tried deleting recently downloaded apps (just downloaded a lot of new ones for my travels –maps.me, spotify, etc.). I’m currently in Hanoi, Vietnam so it’s very difficult to find a legit place that will fix my phone and it is very hard to travel without a phone so I’m very desperate. so any help will be greatly appreciated. Thankyou! — Grace

Solution: Hi Grace. The first thing that you want to do is to try another original Samsung charger. The current charger may not be working properly at this time, leading to erratic charging sessions. If that’s not that, the problem can be caused by either an unknown software glitch, or a hardware malfunction such as a faulty USB charging port or battery.

If you have a spare S5 battery with you, try using it to see if it has something to do with the battery. If you don’t have a spare one, just skip directly to software troubleshooting. That said, you must try the usual dose of software troubleshooting that we suggest. For your case, you must do the basic three — wiping the cache partition, charging in safe mode, and factory reset. If you’ve done them already prior to contacting us, the most likely cause is a bad USB charging port. Try to check the USB port using a magnified to see if there are bent pins or dirt inside. Wear and tear from regular plugging and unplugging or a charging cable can damage the USB port over time. If you’re not careful when plugging or unplugging, you can almost always expect a charging issue sooner. Dirt can also cause charging problems from time to time so make sure that the USB port is cleaned. Try using compressed air to blow particles out of the port. If doing these things won’t fix the problem you must either consider repair, or getting a new smartphone.

Problem #4: Galaxy S5 makes sound notification when Do not Disturb feature ends

I just got a Galaxy S5, having previously owned a Galaxy S4, until it decided to fly out of my hand down some cement stairs, never to work again. Anyway, I use the Do not Disturb feature (or Blocking feature I think it was) on the S4 and it worked fine. Coming out of blocking mode into the sound mode, it had been before it went dark (eg if it had been on vibrate when it went into blocking then it came out of blocking on vibrate as well.) I use this feature most nights on a schedule so I am not awakened by notifications when sleeping. However, the S5 seems to come out of Do not Disturb into full sound, even if it went into do not disturb on vibrate. I am not sure if this is a bug or if I just can’t find the setting to keep it on vibrate.

I work in an open environment and we’re supposed to keep the ringtones to a minimum so I like to have it on vibrate most of the time. In the four days since I’ve had this new phone I’ve gotten a lot of glares from coworkers because I assume my phone is on vibrate all the time like the S4 was, but this S5 seems to not play by the same rules. Any help on this you can offer? Many thanks! — Paula

Solution: Hi Paula. There’s no setting under Do not disturb menu to select vibrate when it deactivates so it’s most probably a bug. Try wiping the cache partition to refresh the system cache and try again. If that won’t work, consider wiping the phone via factory reset.

Problem #5: Galaxy S5 keeps rebooting and won’t load beyond the Samsung logo screen

Hi. My Samsung Galaxy S5 was fully charged and the problem starts when I power off my phone. Later the day, when I power on my phone, the Samsung logo was lacking. Next, the phone just stuck on the T-Mobile logo when it appears. I waited a long time, nothing happen, it just got stuck.

I searched the websites, they said that I have to factory reset. So I did, now the problem continues. My phone did turn on and after the updates, the welcome screen appears, the one where you have to select languages, set up your WI-FI and stuff.

When I get to the part where I have to put the name as the owner of my phone, the screen just go black, but the bar on top the screen still shows. Then the screen appears. Before it lets me do anything, my phone automatically turned off. After a few second, it was on again. So I tried to complete the welcome process for my phone again, same thing happened. And now, my phone just keep restarting. Looks like my phone had no hope. Please help, thank you. — Cici

Solution: Hi Cici. If factory reset did not make any difference, we doubt there’s anything else that you can do on your end at this point. The cause of the reboot issue may be a hardware malfunction so you must try to have the phone checked by Samsung or a third party a shop.

Before going to the service, try to see if you can boot the phone to Odin mode. If you can and it stays stable, you may be able to fix the issue by flashing stock firmware. If you haven’t tried this before, use Google to find a guide.

Here are the steps on how to boot the phone to Odin or Download mode:

    1. Charge the phone for at least 30 minutes.
    2. Press and then hold the Home and Volume DOWN 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 DOWN keys.
    4. Wait until the Download screen appears.
    5. 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.
    6. Use Google to look for a guide on how to do it.

Problem #6: Galaxy S5 screen remains black after phone got wet

Hi. I am an owner of a Samsung Galaxy S5. So a few days ago my family and I went for a little ride to the beach. I totally forgot I had my phone on me and I dived in the water for 1- 5 seconds. I panicked for a second, dried every removable parts in my phone and left it out to dry. We didn’t go home until 6 hours later. I got home, had a little shower and I followed every instruction there was. I used a vacuum to suck out any water then I threw it in rice bubbles(rice crispeys) and the hot water cupid for 2 days. Nothing worked so I did the same process for another 2 days and still nothing worked. I found out that i could use some rice so that’s what I did. 3 days later I took my phone out and it worked! I heard my notifications and felt my phone vibrating but it was a black screen and unresponsive. So I checked out how I could fix that problem. I tried the hard reset and holding the power button for 1 minute, 2 minutes and 3 with battery out and nothing is working. I tried everything the Internet suggested and nothing worked. I thought my phone was going to vibrate again, but I turned it on and nothing happened. Now it has just completely shut down… is there anything you can suggest that could work? — Jaime

Solution: Hi Jaime. Well, since you’re saying that the phone appears to be receiving notifications fine, the problem must lie on the screen assembly. Water may have damaged some components or metallic contacts, rendering it useless at this time. To check, try to boot the phone to different modes. Here’s how:

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 screen remains black or unresponsive after trying all three alternate boot modes, you can assume that the screen is not working at this time. Send the phone to Samsung or to a good third party repair shop so it can be repaired.
