Problem #1: Galaxy Note 5 charging battery erratically, screen turns black

Hi. This morning I used a normal charger for my Note 5 and left it about an hour but surprisingly it shows 28% charged. Then i changed it to the other fast-charging charger and the battery suddenly fully charged in a second. Then after maybe an hour when the battery shows 70% something it suddenly black out. And tried to restart my phone but the battery is 0%. And it keeps happen whole day. What is wrong with my phone? Help me.! —  Arda

Solution: Hi Arda. The system may no longer be detecting the true level of remaining battery power at this time so you want to recalibrate it first. This will retrain the operating system on how to read the battery’s power state. Here’s how it’s done:

  1. Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
  2. Turn the phone on again and let it turn itself off.
  3. Charge the phone without turning it back on.
  4. Wait until the battery says it fully charged to 100%
  5. Unplug the charger and turn the phone on.
  6. If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.
  7. Unplug the charger the turn the phone on again.
  8. Use the phone until you drain the battery down to 0.
  9. Repeat the cycle once.

It will take a few charging cycles before Android may be able to properly detect the correct battery level so try to see if the issue remains after a few days. If it does, do a master reset and observe the phone again. Master reset will restore all software settings to default so if the cause of the problem is software-related, master reset should get rid of it. Here’s how to do that:

  1. Create a backup of your important files such as photos, videos, documents, etc.
  2. Turn off your Samsung Galaxy Note 5 completely.
  3. Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  4. Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  5. Once the Android logo shows, release both the Volume Up and Home buttons.
  6. The notice ‘Installing system update’ will show on the screen for 30 to 60 seconds before the Android system recovery screen is shown with its options.
  7. Use the Volume Down key to highlight the option ‘Yes — delete all user data’ and press the Power key to select it.
  8. When the process is complete, use the Volume Down key to highlight the option ‘Reboot system now’ and hit the Power key to restart the phone.
  9. The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

If the problem remains after you’ve reset the phone, there may be a hardware issue causing it. It can be a bad battery or an unknown logic board error so you must send the phone in for repair or replacement. We suggest that you try Samsung first but if that’s not possible, try any independent service center.

Problem #2: Wet Galaxy Note 5 won’t power back on

So my mom dropped her phone into a foot bath on Saturday. I’ve tried doing all of your reset options with her dead phone and so far nothing is working. The phone will neither turn on nor give a signal that it’s charging. And with the Galaxy Note 5, it’s not like I can just pop out the freaking battery. My issue here is that she has pictures on this phone and I don’t know how to get them off. Our bs Verizon Cloud is full so nothing has been backed up there in a while. Is it beyond hope to retrieve these precious pictures? I did call and get a replacement phone sent to her, but I don’t want to transfer everything over and risk losing the pictures. Help me please! — Destiny

Solution: Hi Destiny. Unfortunately, you need a working phone in order to access contents of a Note 5’s internal storage device. The Nand chip requires power and a working operating system in order to work. If the phone no longer responds at this time when you try to turn it back on, that’s a clear sign of a hardware failure. This means that you may no longer be able recover those files unless water damage is only isolated to the battery. In that case, a simple battery replacement will easily fix the problem. Otherwise, you really have to send the phone in for repair.

Before you do that though, consider booting the phone to other alternate modes to see if you can turn it on. Here are the steps on how to do each:

Boot in Recovery mode:

  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 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. You can either wipe the cache partition or do a factory reset when in this mode.

Boot in 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.

Boot in safe mode:

  1. Charge the phone for at least 30 minutes.
  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.
  6. 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.

Problem #3: Galaxy Note 5 black screen issue

I have a gold Galaxy Note 5. I got it in December 2015 so my one year warranty just ended. I have been having problems with this phone ever since i got it from battery consumption to shocking glitches, to overheating. But the major problem now is that the phone screen is blacked out and a blue LED light at the top far left stays on.

So, last week i was on my phone and it started glitching like the screen kept flashing black and blue. Then i pressed the home button to lock it to turn the screen completely black and pressed it again to turn the screen back on. It was still doing the same thing so I then decide to turn the phone off. It powered off but when I tried to power it back on the screen stayed black and the blue LED light at the top far left corner stays on. I then proceeded to contact AT&T customer support. The first rep told me he had a similar problem when he had a Note 4 and that it was just a battery problem, that i was using the wrong charger.

I have been using the same charger that has came with the phone brand new out of the box. Keep in mind that every time i had an issue with the phone I take it to my nearest AT&T store and they always tell me that the problem is common and it will go away.

Back to the story, so the 1st rep told me he was going to order me a new charger and have it shipped to my house for free, and said if that doesn’t work than they should be able to swap the phone out for another refurbished Note 5 free of charge no problem. He said to let my phone charge on the new charger for about 2 hours.

I needed an immediate solution so when i got home i called AT&T customer service again. The second rep to me that it had nothing to do with the battery, that it’s a software issue. I didn’t know what to believe and i didn’t want to go back to the AT&T store closet to me, so i went to a different store. After I handed the phone to a salesman in that AT&T store, he dropped and cracked my phone. He really didn’t speak on that situation and instantly changed the subject back to what is the problem with my phone. So, I told him everything I told you and he gave me a card for a screen repair shop and told me to call the number on the back of the phone because he don’t know what to do, and that since i still have insurance that I could replace the phone for $125. Then I told him that the first rep told me i can get another one for free, and he pretty much said he didn’t know what he was talking about. So I call Samsung and they tell me that they will email me something for my statement and something to ship my phone off for them to look at it and i haven’t received either. I tried to tell the Samsung rep but she was very disrespectful and really wasn’t trying to hear about my problems. So really I feel like Samsung and AT&T are trying to screw me over! — Darrion

Solution:  Hi Darrion. Based on the problem description above, we think that the second AT&T representative is correct to assess that the screen is broken and you need to have it replaced. The flickering screen issue that you experienced before you went to the store is a classic symptom of a failing screen assembly. The blue LED light  is a sign that the phone is powered on but the screen has failed. This means that there’s no way you’ll be able to fix the issue by doing some software troubleshooting.  We know how difficult it can be sometimes to talk to customer service agents but your only hope here is to either send the phone to Samsung, or go with the suggestion of the first AT&T support rep to have the phone replaced for free. Whether the replacement is really free or not depends on the contact you have with AT&T. As far as manufacturer’s warranty is concerned, Samsung only provides the standard one-year warranty for their device so you’re out of luck.

Problem #4: Galaxy Note 5 can’t install Android Nougat update

I have been trying to install the Android 7 on my phone all day, and it’s taken 4 downloads and it still keep failing. The install hits 26% and it stops, telling me the install failed. I’ve already tried wiping the cache partition and still no luck. It would be ridiculous if I have to factory reset my phone just so I can update my phone. Even if I try to ignore it, it keeps downloading the file (1.4G) on my phone and wasting valuable space. Any ideas? — Ryan

Solution: Hi Ryan. That your phone is not fully downloading the installation files is certainly a sign that something’s not working properly. If you’re positive that there’s enough internal storage space available for the installation (at least 1GB) and the phone is not rooted or running unofficial firmware, factory reset may be your only remaining solution for this problem.

If the phone continues to fail to install the update, take note of the exact error message (and code if available) and contact your carrier so they can take a look at it.

Problem #5: Galaxy Note 5 battery won’t charge fully

I have a Samsung Galaxy Note 5. Earlier this week the phone started cutting off and showing 0% battery life. I would charge it and then it would show 60 to 80% battery life and then less than 10 minutes later shut itself down again showing no battery. I held the power button volume and home button all down simultaneously and clear it out the cache a as recommended by another site. At this point now I can only get the phone to charge up to a maximum of 17%. Even with the original charger it will not go higher than that. The phone is less than 1 year old. —        Josh

Solution: Hi Josh. Try to recalibrate the battery first to see if that will fix the problem.

  1. Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
  2. Turn the phone on again and let it turn itself off.
  3. Charge the phone without turning it back on.
  4. Wait until the battery says it fully charged to 100%
  5. Unplug the charger and turn the phone on.
  6. If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.
  7. Unplug the charger the turn the phone on again.
  8. Use the phone until you drain the battery down to 0.
  9. Repeat the cycle once.

If that won’t fix the problem, do a factory reset then observe it for a day.

  1. From the Home screen, tap the Apps icon.
  2. Find and tap the Settings icon.
  3. Under the ‘Personal’ section, find and tap Backup and reset.
  4. Tap Factory data reset.
  5. Touch Reset device to proceed with the reset.
  6. Depending on the security lock you used, enter the PIN or password.
  7. Tap Continue.
  8. Touch Delete all to confirm your action.

If the same issue occurs after a factory reset, you can assume that the battery may be defective or there’s an unknown hardware issue causing it. Contact Samsung for repair or replacement.

Problem #6: Galaxy Note 5 won’t turn back on

My Galaxy Note 5 continuously reboot and start. I can not get it to stop. I have  held the Power Key, Home Key Volume down key at the same time and it still will not start up…it just keep start and stop. I was on “MSN News” when it started this crazy cycle. HELP!

I took it into the store and the lady suggested a total system download but I do not want to lose my pictures, contact lists…etc. I do not know how to tell if I have the Marshmallow since the phone will never start. — Mamie

Solution: Hi Mamie. If your phone won’t boot up normally, the only available solution for you is to try to power it up by doing a number of different hardware button combinations like the ones we suggest for Destiny above. If the phone remains unresponsive or the different hardware button combinations won’t work at all, you must have the phone repaired or replaced. Unfortunately, repair may delete everything from your phone, especially if you send the device to Samsung so there’s really no positive news for you here.

Problem #7: Water damaged Galaxy Note 5 touchscreen not working properly

Hi. I have a Galaxy Note 5 with a non-removable battery. It fell into the toilet but i took it out as fast as possible and dried it and shook the phone so that the water that entered inside through charging port and speaker comes out. switched off the phone immediately and switched it on again after 5hrs to see if it’s working. it worked fine but the touch did not work properly so i switched it off and kept as is. Is there any chance of it working properly after getting it repaired, or can you tell me the amount of damage done. — Shilineme

Solution: Hi Shilineme. There’s no way to determine the extent of the water damage unless you turn the device back on and see how it works. We don’t recommended that you turn the phone back on though without doing the necessary “first aid” such as dismantling, cleaning, and drying of the parts. Turning your phone back on while there’s still water inside can further extend the damage. Also, leaving the battery inside while water is present can have similar negative impact on the hardware so you want to open the phone up, clean it, and leave it in a bag of rice for a week or longer. The longer moisture stay inside, the higher the chance of extensive damage becomes. Some components may become corroded which can result to long term, permanent damage. Some device that got wet may not show problems immediately but once corrosion develops in the logic board or in the connections, the phone may suddenly stop working, long after it got wet. Doing this first aid procedure though won’t guarantee a fix but we still recommend that you let a professional do it for you to lessen the chances of permanently damaging the hardware.

In conclusion, it’s really hard to know for sure the amount of damage on your device.
