Problem #1: Galaxy Note 5 screen suddenly keeps blinking  and turning into gray

Hi, first let me start by saying Thank You for having this site/Facebook page to go to. i was a nervous wreck until i found you. Ok I have my daughter’s Samsung Galaxy phone.

As of 5 days ago the screen started to fade in and out a bit. Now as of today, the screen runs amok! It just keeps Blinking on and off, slow at first, then real fast. the phone has not been dropped nor wet or any physical damaged done to it by us. My hubby was playing his game like he does every day, and it started blinking. i turned it off, and charged it, screen gets like a grayish fog look to it, turned back on, and continues to blink even a bit of screen shaking too.

I’m lost. It’s my daughter’s phone, and i cannot afford to buy her a new one, nor get it fixed by tech. I truly hope this is a fix it type of problem. The only thing i downloaded new was the Clean App, has a small broom icon, so it can keep it clean from junk. oh yeah and it keeps updating continuously,, which stops me from doing whatever I’m doing at the time. very slow too. it was never like that prior to this week. ok thanks again, anxiously waiting your response. Have a great day. — Cookie

Solution: Hi Cookie. It doesn’t need any more description to give us a picture of what’s happening on your device. Apparently, you have a screen malfunction at hand. Anytime a smartphone screen starts changing colors or begins blinking on its own without user input, a user should know that the screen may be damaged for some reason. The actual cause may not be entirely known but we’re most probably looking at hardware failure here.

Still it doesn’t totally eliminate the chance of software or firmware issue as well. If you’re positive that the phone was never dropped or did not see water, doing some basic software troubleshooting can be worth your while. The first thing that you want to try is to boot the phone in safe mode. Your objective is to check if enabling safe mode changes some things and importantly, to see if a third party app is to blame. While in safe mode, all the apps you installed after the initial setup will be prevented from running. This will help you identify if indeed, one of the third party applications is causing a conflict with other apps or firmware. To restart the phone in safe mode, kindly follow these steps:

  • 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.

Booting in safe mode is not a solution per se but rather a tool to check if an app is the root of the problem. If the screen works normally while in safe mode, that’s a confirmation of our hunch. The thing is, there’s no way to know for sure what app may be to blame. You have to use the process of elimination to identify the problem.

Now, if nothing changes even when on safe mode, you can also do a more drastic solution by wiping the phone clean via factory reset. This will be the last thing that you can do on your end. Again, our aim here is to check if the issue is being caused by a software glitch. To do it, just do the steps below:

  • Turn off your Samsung Galaxy Note 5 completely.
  • Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  • Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  • Once the Android logo shows, release both the Volume Up and Home buttons.
  • 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.
  • Use the Volume Down key to highlight the option ‘Yes — delete all user data’ and press the Power key to select it.
  • 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.
  • The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

If nothing changes after a factory reset, you can safely assume that you definitely have a hardware failure. Difficult it may be for you but the only resolution available is either screen repair or phone replacement.

Problem #2: Uber map not loading in Galaxy Note 5

I have the problem showed before: “Since using my Samsung [Galaxy] Note 5 I have not been able to load the map in Uber. I have restarted my phone, updated the app, uninstalled-installed it, restarted my phone, did soft reboot but still no map was loaded. It cannot be a connection problem [].” I took all steps that you provided. Nothing changed. All the third apps work well (in common mode).The phone doesn’t show any messages about errors. I was allowed to login in my Uber account, but there was no button “home” that usually lead me to the map. The next attempt to load map by clicking icon just show the regular process trying to enter Uber system (map) unsuccessfully. — Mikhail

Solution:  Hi Mikhail. If you followed all our suggestions in this post, including a master reset, then you have a confirmation that the issue has nothing to do with your device but rather app-specific. This means that there may be some coding issue that must be fixed by the developer before it works properly again. Be sure to contact Uber or the app developer for more direct assistance.

Problem #3: Galaxy Note 5 keeps freezing after latest Marshmallow update

After the recent 6.0.1 update, my Note 5 has started behaving peculiarly. It freezes when I am using Facebook or Whatsapp app. Instagram works well. I used the CPU overlay and saw that there is a sudden increase in the low priority processes and then it freezes. Once the low priority process (blue band) reduces it again starts working normally. I have done cache delete and have formatted the phone fully. Still no avail.

Today it switched off and did not turn on. I read your blog on how to troubleshoot galaxy note 5 that doesn’t turn on. I held the power button. It started again but switched off. There are continuous unwarranted and unexpected restarts, lots of freezes.

I was thinking of using Odin to downgrade to an earlier version of 6.0.1. Phone was working fine with the first update of Android 6.0.1. The later updates have made the phone buggy.

Is it a firmware problem or a hardware problem? Should I try to downgrade or take it to Samsung service center? The phone is just about a year old. — Bharath

Solution: Hi Bharath. If random restart problem was not present before the most recent Android update, you can bet that it’s a firmware issue. If you installed an OTA (over-the-air) update, make sure that you let your wireless carrier know so they can tweak some codes and release a patch. keep in mind that not all OTA updates are perfect so making sure that the developer team know of the issue is a good first step towards resolution.

Problem #4: Solution to random restart issue on Galaxy Note 5

I’m not sure which Android version I have because my phone was running out of memory so I didn’t have enough memory to update my phone to the latest version. Last time I updated my phone was probably close to a year ago.

My phone will restart itself when I am using it and It will stay on the AT&T screen (white screen with att icon in the middle) and will stay on that screen for hours lit up. I have to hold the power off button to get the phone to restart. it will restart and come to my home screen and only load a few of my icons on my main page and freeze and stay lit up. I can’t lock the screen and I can’t use the touch screen or any buttons. I will restart my phone as many times and it just does the same thing over and over. most of the time it goes to my home screen that freezes, and about every 3 times I restart my phone it will go to the ATT page that I described earlier.

I get lucky to be able to get my phone to actually turn on and work. About after 60 times of restarting my phone I can get it to work, but that’s whenever the phone feels like it wants to work.

The last time my phone was on and working was Sunday and it was on for about 1 hour before it randomly restarted out of nowhere.

I was trying to transfer my pictures to my SD card just in case my phone decided to not work again, which it did. I’m not sure if it would be an internal problem.

I went to my ATT store and they said most likely I’ll have to get it fixed, nothing they could do to it.

Even when my phone is stuck on my home screen, my phone will randomly restart and go to either the ATT page or my home screen frozen again. It has a mind of its own.

I try to let the phone charge fully before I try to turn it on because of how sensitive my phone is now.

Is there any hope for my phone?? — Missy

Solution: Hi Missy. Addressing a random restart issue on any Android device requires checking several things. We’ll give you a brief outline of things that you can do to narrow down the cause of the problem.

Calibrate the battery

For the earlier iterations of Galaxy Note devices, doing this troubleshooting is straightforward by simply removing it from the device and inserting a new one. This is clearly not the case in the new Galaxy Note 5 due to its non-removable battery pack design. This makes it doubly harder for a user to know if the battery has end its end-of-life. The best a Note 5 user can do is to calibrate it and hope for the best. To calibrate your Note 5 battery, follow the simple steps below:

  • Charge the phone until the battery level reaches 100%.
  • Drain the battery to 0% by playing some games and doing resource demanding tasks.
  • Charge the battery up to 100% again.
  • Drain the battery to 0% one more time.

Doing battery calibration ensures that it has  a stable state of charge. There’s a chance that the reason for the random reboot is the battery not really showing the true available charge for some reason. Calibrating it should easily fix this common issue on Lithium-based batteries.

Watch out for overheating

Overheating is usually a result of a problem rather that a cause. If you notice that your phone gets unusually warm before eventually dying off, you must continue isolating for the actual cause of the problem. Overheating often accompanies random reboot issue. If these two are present in your device, there’s high likelihood that you have a hardware malfunction. It still doesn’t mean though that software is not to blame. Malware, virus, or problematic app or services can also lead to overheating. Try checking the battery usage section to see if there’s any app or service that stands out in terms of power consumption. If you are not familiar with a service or app in that section, you may have a malware infection at hand. If everything looks normal under battery usage section, you most likely have a hardware malfunction. It can be a bad battery or any other component in the motherboard.

Uninstall recently installed apps or updates

If the random reboot issue appears to coincide after you installed an app or an app update (not an Android update), consider uninstalling it to see a difference. Sometimes, poorly coded apps or updates can cause conflicts resulting to all sorts of problems. Promptly uninstalling said app can save you a lot of trouble.

If you think that you may have installed something prior to noticing the problem but you can’t remember exactly what it is, you can also try to boot your phone in safe mode (steps provided above).

Wipe the system cache

While we rarely hear of corrupted system cache leading to random reboot, we still highly suggest that you wipe the cache partition. Doing so will force the phone to build another system cache. Here’s what you need to do:

  • Turn off your Samsung Galaxy Note 5 completely.
  • Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  • Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  • Once the Android logo shows, release both the Volume Up and Home buttons.
  • 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.
  • Use the Volume Down key to highlight the option ‘wipe cache partition’ and press the Power key to select it.
  • 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.
  • The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

Do a factory reset

Finally, if nothing works, don’t hesitate to do a factory reset. Your goal in doing so is two-fold. One is to make sure that you remove unwanted firmware glitch that may have developed overtime, and the other to let you observe how the phone works once a clean firmware version is re-installed. Be sure to observe the phone for at least 24 hours after a factory reset. Don’t install any app during the observation period.

Contact Samsung or any relevant party for repair request or replacement

If all the procedures above won’t work, you can safely assume that hardware malfunction is to blame. Knowing exactly where the problem lies is not easily done. The phone has to be physically checked in order to identify the cause. If the phone is covered by a warranty, make sure that you use it to get a resolution.
