Problem #1: Galaxy Note 5 screen is black and won’t turn on

I have a Samsung Galaxy Note5. While in use, I was reading from my Kindle App and with no warning the screen went completely black and the the far top left corner a green light began flashing consistently. It has been a week since this first happened and this green light is still flashing. I watched the videos on YouTube and I tried all 15 different combinations to force a reboot, for instance, pressing and holding the volume down button as well as Home button. None of these worked. There’s been no sound and nothing but the black screen. I have checked the phone thoroughly, there’s no obvious damage. I have checked the SIM card slot, there’s no liquid damage. But I need my phone and it’s going on a month. I am losing it. The phone was purchased from US CELLULAR but I run the phone off wifi and/or prepaid Straight Talk.

Forgive me if there’s a info overload there. I am not tech savvy and do not know what info is relevant. There’s nothing more I can think to mention. I am desperate and really looking forward to hearing back. Thank you sincerely. — Samantha

PS: I’m not aware what Android version the phone is.

Solution: Hi Samantha. The persistent green LED light is an indication that your phone still turns back on, but not the screen. This means that the problem lies on the screen assembly only. If you dropped the phone before contacting us (we’re wondering why you did not mention that together with liquid damage), it might have damaged the screen. There’s no point asking for support from us if that’s the case because there’s nothing that we can do to help. Even if the phone was never dropped before, there’s still little to nothing that we can give you to fix this issue. We’re pretty sure that we make it a point in our posts which deals with this type of issue that if you can’t boot the device to any other modes (safe mode, download mode, recovery mode), you must have the phone repaired. Unless you have the necessary expertise and tools to remove and replace the screen, there’s virtually nothing that you can do on your level.

If the phone is still covered by a warranty, make sure that you contact the right party to have it repaired or replaced.

Problem #2: Galaxy Note 5 screen keeps turning on and off when it is locked

Hey, So this morning when I went to unlock my phone (I just have the regular swipe lock screen) my phone screen kept flashing on & off. I’d hit unlock, it would flash on but then flash off before I could unlock it. It happened over & over. I was able to unlock it by swiping really quick before it flashed off again but it still flashed off after I unlocked it. I tried holding down the button to restart it a couple times & it didn’t work right away. It took multiple attempts to restart. Even after I restarted it did the same thing. After a while it just stopped doing it but I haven’t locked my screen again to see if it’s going to do it again. Have you heard of this happening before? Help! — Liz

Solution: Hi Liz. It’s our first time to hear this issue in a Galaxy Note 5, or to any Samsung device, so it may be an isolated case. There may be an operating system glitch causing it, or something in the hardware so your best chance right now is to do basic software solutions.

Delete Note 5 system cache

You can start by wiping the cache partition. Sometimes, the system cache, which is kept in the cache partition, becomes corrupted after a system update or app installation. A corrupted system cache can lead to apps or functions in a phone to behave erratically, so it’s good if you can regularly wipe it. This will force the phone to build a new system cache. To do it, check out 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 ‘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.

Observe the phone in safe mode

Another good thing to do in this case is to observe how your phone behaves when it’s on safe mode. One of the installed third party apps is having a conflict (bug) with the operating system, resulting to abnormal behavior of the screen when it’s locked. If the issue won’t appear when the phone runs in safe mode, that’s a clear indicator that a third party app or service is to blame. These are the steps on how to restart your Note 5 in safe mode:

  • 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.
  • Try to replicate the issue by locking the screen again.

If you think that there’s a bad third party app installed, you must then invest some time to identify it. You can do this by removing third party apps one by one and making sure to replicate the issue after every uninstallation.

Install updates for Android and apps

Updates are released for a reason so see to it that you install them once they become available. Developers release patches to their products whenever they discover issues so it’s always good practice to install them everytime. This goes true for both pre-installed and third party apps.

Reset all software settings back to factory default

Now, if the issue remains after wiping the cache and booting the phone to safe mode, the glitch may be on the operating system itself or on one of the pre-installed apps. Doing a factory reset is the only step that you can do in this case. If you haven’t tried it before, make sure to follow these steps:

  • Create a back up of your important files and contacts. Files on the SD card will not be affected by a factory reset but make sure to unmount the card prior to doing the procedure.
  • 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.

Problem #3: Some portions of Galaxy Note 5 screen not responding to touch

Hi. I’m wondering if you could please advise. I have a Samsung Galaxy Note 5. I’ve only had it for 6 months and since a few weeks ago, the touch is not responding. The stylus has completely stopped responding. The weird thing is some parts of the screen seems to respond to finger touch. However not some parts of the screen.

I have done factory reset a few times and nothing seems to work. It starts to work completely fine then after a few days, only part of the screen rends to touch and maybe after a few hours the same thing happens again. but now only part of it is working. I have also held the shut down button and home screen with the volume button together where a blue screen comes up and left it over night but it just says its downloading something but nothing seems to work. — Arooj_abbas

Solution: Hi Arooj_abbas. There’s a chance that the screen digitizer, one of the major components in a screen assembly that converts analog touch signals into digital input, is damaged, or has stopped working for some reason. To check, try to access the phone’s service menu by dialing “*#0*#” (without the quotation marks) on the phone app. Once you’re in the service menu screen, tap the “Touch” option and draw a line all over. If there’s a portion in the screen that does not register your touch, that’s clear proof that the digitizer is not working properly. Because digitizer replacement is a complicated process, we recommend that you let Samsung do the job. If there’s no nearby Samsung repair center, bring it to a local service center. Better still, try to find a way to have the phone replaced instead.

Problem #4: LinkedIn app won’t load on Galaxy Note 5

Hi. I’m having problems with the Android LinkedIn App. As of 18th November, the App failed to launch. When I tap the LinkedIn icon it just goes to a white screen with no error message and then returns to the main phone menu screen. Prior to this the LinkedIn app was working fine, as were all the other installed apps.

I have uninstalled (messages confirms App is compatible with mobile) and re-installed the LinkedIn App twice and it still won’t launch. Any suggestions how to get it working?

I have again uninstalled the app and reinstalled (version 4.0.89) from Google Play but even after installation and tapping the Open button the same white screen is shown and it does not launch. On checking the Accounts and attempting to Add Account, LinkedIn is listed (with grey dot, not active) but tapping it has no effect, ie it does not make the dot turn green, or open the account setting options.

I’ve also tried clearing defaults, cache, and data for the App in Application Manager, but not change All other Apps (e.g. Facebook, Gmail, etc) are operating without problems on the phone. I’ve check, wifi connections and Security setting but can’t find any obvious issues. — Greg

Solution: Hi Greg. There are two things that you can try here. You can either do a factory reset to see if there’s an unknown operating system glitch that prevents the app from loading, and/or contacting LinkedIn app developer for support. Either way, you should be able fix the issue.

Problem #5: Galaxy Note 5 networking function acting up after installing VPN Easy app

Hi. So a few weeks ago, my phone was just fine. Then at school I downloaded the app VPN easy and my WiFi started acting up. I looked up online for ways to fix it and I’ve tried many of them. I have deleted the app, reset my phone, reset my setting and nothing seemed to work. Before I downloaded the app, I had gotten 2 or 3 bars of Internet in my room and now I get none. Rarely I get one bar, but it normally lasts not even a minute.

Now, at the moment my phone is shut off because I haven’t paid the phone bill but I know that has nothing to do with it. So my phone is basically running off wifi right now. There is nothing wrong with my wifi router. My friend that lives with me has the same exact phone and she gets 2 to 3 bars of wifi service in my room, as what I use to get. Please help me solve this. I want to try everything possible before resetting my whole phone. Please help — Allicia

Solution: Hi Allicia. VPN Easy is an app that changes some network configurations in a device to allow it to work. The modifications may resulted to a conflict or bug, resulting to the erratic behavior of the phone’s networking capabilities. Because uninstalling the app did not appear to work, we highly recommend that you reset all software settings back to their default state via factory reset. This is the only way to make sweeping changes to everything, including all networking values in your phone. Refer to the steps above on how to do this.

Problem #6: Wells Fargo app won’t load in Galaxy Note 5 | Galaxy Note 5 keyboard app not working properly | Predictive text not working on Note 5

I have 3 issues.

  1. Smartphone gone Stupid. Supposedly there were nearby tower fixes going on 1-2 weeks ago. Was having basic access issues. Those are better, but other issues remain.
  2. I use a bank app, Wells Fargo, almost every day. In this same 2-week period, I cannot access it. Upon clicking on the icon, there is a pause, & on the intro screen, at the bottom left, it shows, “Access Denied.” If I try to enter Username/Password, I get an error message saying that there is a problem with internet connectivity. There is not. I called Wells Fargo, and they think all is fine. I uninstalled & reinstalled, but no change. Any ideas?
  3. Smartphone gone Stupid. Same timeframe. The phone no longer does word-recognition. As in, you are typing in something, anything. This for example, but you no longer see the bar showing potential word choices that could be used to speed things up. Not in any function. The only thing close that does still work, that is similar, is when I type in a Google search, and it still “anticipates” my choice of search entry. This problem is making me want to throw this phone across the room. I have to go into my Boost Mobile store today to pay my bill, & I know they will have no clue. I called Tech Support & they didn’t, either. Any ideas here, also?

I do not know the correct OS Version. Thank you, Sincerely. — Karen

Solution: Hi Karen. For the first issue, there’s nothing that we can do to help you with that. You must work with your wireless carrier to iron out everything because we have no idea what they’re doing.

For the second issue, you must try to check if the issue is internet connectivity related or not. You can do that by opening the Wells Fargo app when you’re connected to a wi-fi network and not on mobile data. If the same thing happens, there may be something in your phone that prevents that app to load properly. Try doing a cache partition wipe and factory reset to resolve the problem. Refer to the steps above.

For the third issue, the problem may have something to do with the keyboard app you’re using. Try to clear the cache and data of the keyboard app to fix it. Here’s how:

  • Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  • Navigate down to “Apps.” This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  • Once in there, find the keyboard app you’re using and tap it. If you’re not sure which keyboard app you’re using, check it under Settings>Language and keyboard>Default keyboard in advance.
  • You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  • You should now clearly see the Clear Data and Clear Cache buttons for the application.

Once you’ve cleared the default keyboard’s cache and data (assuming you’re using Samsung keyboard), make sure to also turn on Predictive text under Settings>Samsung keyboard section.
