Problem #1: Galaxy Note 4 instability problem after updating to Android Marshmallow

Hello! I am very thankful there is someone so nice out there. I have a Note 4. It is the most important device I have because: As a cancer survivor trying to rebuild my life and career by creating a VR Startup company dedicated to creating Technology Assisted Teaching Tools to help home and small school engage students in a truly immersive and effective manner. I call my company SchoolHomeVR.

The trouble: I got the 6.0.1 update (automatically) and it made things really bad, then I happened to fill my internal chip too much and it got REALLY bad.

Details: After the update, it would always, after every boot say: Finalizing Update then say “Update Successful.”

I have emptied the cache, I have done a Factory Reset (it stayed at 6.0.1 unfortunately).  I can barely get it to boot. I have to charge the battery to full (I have more than one battery, same thing all) then take and keep the battery out for a few minute then I can get it to boot but it reboots by itself spontaneously so soon. I can barely get the options checked.

I have read I need to DOWNGRADE to 5.1.1. using ODIN 3 , Samsung USB Driver and the md5 file that corresponds to my model (which is N910P) and downgrade from 6.0.1. When I tried it, it Connected to the phone, (as COM port thingy) but when I tried to start ODIN it said FAIL. So I did more research, A different video says, before ODIN I need to 1) Enable USB Debugging (I think I finally got that one) 2) Allow Unknown Installs, (I keep trying to do this one it always reboots right before i can click the final ok!) 3) Delete cache in setting,.. I am still trying constantly to do these things.

I am so depressed about this, this was not a toy this was my Work Tool. I just got the NEW Version of the Gear VR so I could SEE the WORLDS I CREATE (I am an Animator and CGI Artist, APP Developer). This was my way back to life, I see no way to come back now. I have never in my life thought about suicide but it is a constant thought this week. I’m obsessing on the thought that it’s all just too hard and I never catch a break. There’s nothing to look forward to, nothing good will ever happen again in my life. The other half of me is still driven and think I can ACTUALLY get Funding as a VR Startup (well I could, I was making my Investment Deck THIS WEEK to apply for Virtual Reality Startup Funding,.. and am now stopped dead in my tracks because of this killer update. Well, there it is, I’m one VERY DEPRESSED Artist and Musician. I don’t think there is anything that can be done, I’m trying what should be the thing to do, but there is never any complete info out there. Every site I go to says something the others ones seem to have forgot to mention, the end result I never GET THERE.

Well, thank you again for being out there if you still are. You will very likely save a life if you can get me back to being productive. I see no way forward right now, and I have no interest in being there for what it will be like if I can’t make this happened and pull myself back out of the post-cancer hole. (I was at hospital for nearly 3 years, in intensive scare for 7 months with a cancer so rare it didn’t even have a name. I was saved by a UCLA researcher who NAMED the disease and used an OFF Label Chemo agent at VERY HIGH DOSES (AWFUL AWFUL AWFUL but it saved me). I have probably been as sick and gone as low as anyone ever has and still come back. I think they had a chaplain come in at least 3 times over those years, to read my last rights etc,. thinking that was it. PLEASE help if you can, it would mean literally everything to me. If you have any need for VRGraphics or an animated LOGO or a custom Orchestral Musical Piece (with my tools I can sound so close to a real full orchestra you’d think it’s the Royal Philharmonic at Abbey Road! Really!! ) or any number number or small to medium project I would be more than happy to help back!

Thank you for your time. Don’t mind CC any email you send back, to [email protected] I am starting to have trouble with my other email but don’t quite trust my NEW Email to fully switch over yet 🙂 😉 — Robert

Solution: Hi Robert. First of all, we don’t think this issue, or any other problem, is worth losing your direction in life. The worst that can happen with the phone is that it will become permanently bricked. You can, of course, always replace it and move your life forward. You don’t even need to get a brand new replacement as affordable refurbished units are readily available. We hope you don’t compare the value of your life to that of a Note 4.

Secondly, we also hope that you’ll read this post in a timely manner. We don’t send our responses via email as we want other Android users to also access all our posts.

Thirdly, there are five things an Android user must do if problems occur right after installing a system update:

  1. wipe the cache partition
  2. factory reset
  3. install app updates
  4. uninstall incompatible apps
  5. revert to older Android version via flashing

We understand nothing has improved after wiping the cache partition and performing a factory reset so you must ensure that you do the items 3 and 4. Only after doing 3 and 4 are you supposed to flash older Android version. Sometimes, an outdated or incompatible app can cause instability problems after a major system update. It’s your responsibility to ensure that this does not happen. Keep in mind that not all apps are created equal. One may work properly in Android Lollipop but not in Android Marshmallow. It’s your job to ensure that you update and install only compatible apps.

To see if a third party application is causing a problem, you can try to boot the phone to safe mode. Safe mode, in itself, is not a solution. Rather, it’s a means to an end. Safe mode blocks third party apps and services so if the problem won’t occur while the phone is in safe mode, one of the third party apps in the phone must be causing the problem. To boot your Note 4 to safe mode, follow these steps:

  1. Turn off the phone completely.
  2. Press and hold the Power key and the Volume Down key.
  3. When the phone starts to boot, release the Power key but continue holding the Volume Down key until the phone finished restarting.
  4. Safe mode will be display at the lower left corner; you may release the Volume Down key now.

Remember, safe mode won’t pinpoint the problematic app. If the issue won’t happen, that’s a confirmation of our hunch that one of the apps is to blame. You must try to uninstall apps one by one and observe how the phone works after every uninstall to identify the cause.

If nothing works after uninstalling all possible problematic app/s, you can try manual flashing via Odin again. If it fails this time around, there must be something wrong in the phone that causes it to not recognize commands in Odin mode. It’s impossible for us to know what the real problem is so you should consider having the phone replaced if you can’t get it going.

Problem #2: Galaxy Note 4 keeps restarting on its own

My device has been having problem even before I updated it to Marshmallow. It turns on and off by itself and at times it shows the ODIN MODE (which I have no idea of). So I decided to update it thinking that it will solve the problem but it didn’t. So I factory reset it, the usual on and off lessened but my device still lags and turns on and off at times, the same with the ODIN mode when it lags for a long time. I troubleshooted it. Basically almost done all the solutions I can come up with. Then I thought the battery was the problem because it always starts to turn off by itself when the battery is at 20% so I always charge it before 20%; it kind of worked occasionally. I also noticed that when an app needs an update it goes to ODIN mode or simply turns on and off. The worst case is when it turns off and it won’t charge at all. There is no LED Light indicating that it’s charging. I tried the soft reset but it won’t work. Usually when this happens I just leave it alone and when I try to turn it on after a day or two, it will vibrate which means it needs to charge and the whole thing happens again. Lags, turns off, wont charge, wait, charge, turns on and then lag. I don’t know what’s the problem and its making me crazy. Please Help!!        — Flrsrthm

Solution: Hi Flrsrthm. A random reboot issue like the one you’re experiencing can be caused by a number of causes including bad battery, software glitch, incompatible/outdate apps, overheating, or other unknown motherboard malfunction.

We suggest that the first troubleshooting step you take is battery calibration. This process helps the operating system read the true battery levels. 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.

If battery calibration won’t fix the problem, the next thing that you want to do is to boot the phone to safe mode. This will help you check the possibility that a third party app may be causing the problem.

  1. Turn off the phone completely.
  2. Press and hold the Power key and the Volume Down key.
  3. When the phone starts to boot, release the Power key but continue holding the Volume Down key until the phone finished restarting.
  4. Safe mode will be displayed at the lower left corner; you may release the Volume Down key now.
  5. Observe the phone in this mode for at least 24 hours.

Should nothing change even when the phone has been booted to safe mode, other issues, most probably hardware malfunction, is to blame. Try to use another battery to see if that will fix the problem. If that won’t work either, send the phone to Samsung so it can be repaired or replaced.

Problem #3: Galaxy Note 4 won’t charge properly

Hello. I’m having a very weird problem. It started last weekend when the phone decided not to charge or turn on in an outdoor cold place. Then I charged again when I was in a warm place. Problem happened again so everytime I unplug battery then put it back and tried 3 different USB. … it would charge after few trials then this method stopped working with any USB I own (3). … battery level would be very low… so I thought it is either the charger port in the phone not working or battery dying.

I tried a new battery, asked the store to check if charging. it was at 67%, new one. They tried to charge it with their own USB. … it did not charge so they said it is a loose charger port in the phone and cannot be repaired because it is stuck to the screen which might get damaged and will cost too much so take this external battery charger and charge your battery then plug-it back. I have been doing that since yesterday. The battery does not charge fully with the external charger up to 85%… so after I put it back in the phone, I tried to charge it normally thru the phone USB and it charges! So when it drops to around 80% I plug the USB in the phone and takes like 30 min plus to charge fully! It does not drain fast back to 80% and phone seems to work normally! … weird?! Non?! If battery drops below 75… I cannot charge thru normal USB. I will have to take it out and use external charger.

So the issue is not battery because a new battery has been tested and resulted to the same behavior. I’m not sure if the phone enclosed USB port because it charges the battery with one click when it is above 80%. What could be the problem?! I tried to search online but could not find something related to my problem. Awaiting your reply. Sincerely. — Dima

Solution: Hi Dima. There may be a software-related problem causing this weird charging behavior on your phone. The first thing that you want to try is to recalibrate the battery, forcing the operating system to retrain itself on how to read actual battery levels. Refer to the steps above on how to do it.

Once the battery has been recalibrated, the next thing that you want to do is to wipe the cache partition. Doing so will cause the deletion of the old system cache and forcing the phone to create a new one. An outdated or corrupted system cache can lead to some instability issues so you must do this regularly, even if there’s no apparent issue. Here’s how it’s done:

  1. Turn off the Galaxy Note 4 completely.
  2. Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  3. When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  4. When the Android System Recovery shows on the screen, release the Volume Up key.
  5. Using the Volume Down key, highlight the option ‘wipe cache partition’ and press the Power key to select it.
  6. When the wiping of the cache partition is finished, highlight ‘Reboot system now’ and hit the power key.

Finally, don’t hesitate to do a factory reset if nothing changes. Factory reset will erase everything in your phone’s storage device so make sure that you back them up before proceeding.

  1. Turn off the Galaxy Note 4 completely.
  2. Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  3. When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  4. When the Android System Recovery shows on the screen, release the Vol Up key.
  5. Using the Volume Down key, highlight ‘wipe data / factory reset’ and press the Power key to select it.
  6. Now highlight ‘Yes — delete all user data’ using the Vol Down key and press the Power key to begin the reset.
  7. When the master reset is complete, highlight ‘Reboot system now’ and hit the Power key.
  8. The Note 4 will restart but it will be longer than usual. When it reaches the Home screen, then begin your setup

Problem #4: Galaxy Note 4 screen is damaged, cannot recover files from memory

Hi. I have a Samsung Galaxy Note 4. The screen got all weird recently. My problem is that I have pictures, videos and contacts saved to this phone. When I plug it into my Windows desktop computer via USB, it recognized the device and it “Installs Software For New Device.” However, after it installed the device, my computer doesn’t recognize the phone as a drive under “My Computer.” What is the deal with this phone? How do I get the pics, videos and contacts from my phone. Everything is saved on the phone’s hard drive. I already took the memory card out of the phone and put it in my new phone. Only a couple pictures were on the memory card. The bulk of my data was on the phone’s hard drive. What do I do??!! Please help! Thanks! — Mark

Solution: Hi Mark. Based on the link of the picture above, it looks like the phone’s screen has been damaged permanently. Try to send the phone in, preferably to Samsung, so the hardware can be checked. If Samsung will say that it’s a screen issue, they may be able to replace the damaged part without wiping the phone’s memory. Keep in mind that regular repair with Samsung involves wiping the phone’s storage device so make sure you get a confirmation from them that the storage device will not be touched. If they cannot do an exemption, you’re out of luck. Try having the screen replaced in other independent shops so you can tell them not to wipe the phone’s memory.

Problem #5: Galaxy Note 4 keeps crashing and stuck in Samsung logo screen

I have a Note 4 SM-N910F. Last week I upgraded it to 5.1.1 and everything was fine but after few days it started to crash. I rebooted it but it refuse to start and stuck on the Samsung Note 4 logo and a blue message on the top left corner on the screen “recovery booting…” and starting to reboot itself after 2 seconds. I tried to flash it with Odin with the same 5.1.1 firmware but still not working. I tried different stock firmware for sm-n901f in vain. i can’t enter the recovery mode. The only thing i can do this to enter download mode and i can see this: ODIN MODE (HIGH SPEED) PRODUCT NAME: SM-N910F CURRENT BINARY: Samsung official SYSTEM STATUS: Custom REACTIVATION LOCK (KK): ON KNOX WARRANTY VOID : 0X1 (4) QUALCOM SECUREBOOT : ENABLE (CSB) AP SWREV: S1, T1, A1, A1, P1 SECURE DOWNLOAD :ENABLE UDC START. PLEASE HELP ME. Is the phone still have a little chance to work again ? Thank you. — Rupes

Solution: Hi Rupes. There’s only so much that you  can do when it comes to electronics troubleshooting. If your phone can no longer boot normally or to recovery mode, the only available option left is to have Samsung check the motherboard. Sometimes, flashing or unofficial attempts to modify the software can lead to boot-related problems so you need to reload the bootloader (in Samsung devices, this is also called Recovery mode) and either wipe the cache partition or do a factory reset. If you can not do these two possible solutions, that means the problem is deeper that you think, usually at the bootloader level itself. Unfortunately, there’s no way to fix a bad bootloader but to replace the motherboard. An issue like yours usually results to motherboard replacement so if the warranty of the phone has already expired, you’re looking at spending between $200-300 repair job by Samsung. Motherboard replacement doesn’t work all the time though and sometimes problems can still linger long after the replacement.

Problem #6: Galaxy Note 4 screen keeps flickering due to water damage

My problem is my Samsung Note 4. My issue is that the screen and turning the phone on. A little bit of a backstory which is probably the cause of it, is that I bring my phone with me to the shower just because I feel unsafe without it. It didn’t touch any water since it was on the counter but I tend to have steamy showers which is probably the reason to what is the problem. I thought that the problem would last a day with other sources when water comes in contact with the phone and doesn’t require the rice method but the problem seemed different to the other ones. This was because my phone kept flashing on and off for the screen where it would turn on and then off so when I would type in my password for the screen lock I would have to turn it on and off to get it to stay for a bit. It can still respond while in black screen so I was able to go in.

The other problem with the screen is that there is a thick green line on the right and a thin purple line on the left ( there were lines also during the screen password part and it would even go down where the keyboard is on the phone). The lines would just stay there as well as the flashing.

And one more thing is that my phone, even during the turn on phase it starts to get darker in lighting before it goes black and I have to wait a bit. That’s all of the details I’m able to list. Please reply as soon as you can. — Flarepire

Solution: Hi Flarepire. The symptoms you mention are consistent with a bad screen issue. This means that there’s no amount software troubleshooting or hacks that can fix it. Erratic screen behavior is usually due to hardware malfunction so the only effective fix for it, aside from getting a new phone altogether, is screen replacement. If your phone is exposed to moisture (which is very likely in your case given that you bring it to a steam bath), you may be lucky to find the issue isolated to the screen assembly only. If water particles find their way to the motherboard, you run the risk of having metallic contacts corroded, or some components shorted. Have the phone’s hardware thoroughly checked by Samsung or by an independent service center.
