Note 4 Screen Is Black With Blue LED Light

Problem: I originally dropped my phone and needed the screen replaced, i got it replaced and dropped it again a week later, no cracks nothing but the screen was black, the blue light that shows at the top of the phone was blue so it was still working and i could see the screen light just if i looked at the back of the screen from the top of the phone, my phone also vibrates when turned on and off and when connected to a charger etc. But the screen is just black. What do i do? Also i don’t know my android version

Solution: It appears that the display of your phone has been damaged by the drop. To further check if this is the case you should try to start your phone in recovery mode. If the display works in this mode then there’s a possibility that the issue is caused by a software glitch. You will then need to do a factory reset in this mode. Take note that the reset will erase your phone data. If the display is black even in this mode then you will need to bring the phone to a service center and have it checked.

Note 4 Restarts With New Battery Installed

Problem: Good day the droid guy. I just bought a new battery for my note 4. I bought the extra battery kit that comes with a charging dock if that is what is called. When I used the new battery, my phones starts to restart and can’t even locate my network provider signal. But when I put my old battery then it’s seems to be fine. What do you think is the problem? Is it the phone or battery? My unit is N910C

Solution: If the phone is having issues when the new battery is installed but does not have a problem when using the old battery then it’s very likely that the new battery could be faulty. You can further check if this is the case by backing up your phone data then doing a factory reset. Once the reset is complete do not install any apps in your phone yet. Try to check if the issue still occurs with the new battery installed. If it does then you need another new battery.

Note 4 Not Connecting On Calls

Problem: I have a Samsung Note 4, unlocked AT&T phone with Straight Talk service. Extremely frequently when I make a call it just keeps saying ringing on my screen and it does not connect. When it does that, I don’t hear it ringing. Also, my phone will ring and when I answer it it’s dead sounding and the person on the other line doesn’t hear me either. I have cleared the cache and factory reset. Please help!

Solution: Since you have already performed a factory reset then we can eliminate the possibility of a software glitch causing this problem. The next step that you will want to do is to check if the SIM or network as anything to do with this problem. Try going to different location then check if the same issue occurs. This way you can verify if the problem is network or signal related. You should also try inserting a different SIM in your phone or use your SIM in a different phone to check if the problem is caused by the SIM card.

Should the above steps fail to fix the problem then this is most likely a hardware related problem already in which case you will need to bring the phone to a service center and have it checked.

Note 4 Transferring Photos Via Bluetooth To iPhone

Problem: I’m trying to Bluetooth my galaxy note 4 but it’s not on service, to my iPhone 7 that is on service so I can transfer photos from my galaxy to my iPhone it says paired but not connected.

Solution: While transferring photos via Bluetooth between two Android devices can easily be done by simply pairing both devices this is not the case for the iPhone. In fact, you can’t even send photos between two iPhone models using Bluetooth unless you use a special app. Try installing an app called SHAREit on the Android phone and the iPhone then use this app to transfer your photos between the devices.

Note 4 Turns Off When In Use

Problem: I bought my Samsung Galaxy Note 4 on a Telstra plan, when the plan  ended I had the phone unlocked by Telstra or iinet, I can’t recall, so I could go to iinet. All was  fine for 12mths, until it started to lose charge really quickly. I bought another battery for $25 AUS online, said it was a genuine Samsung. A week ago I notice the phone began to slow down and finally it started to turn off while I was using it. I tried doing a factory reset, but the phone automatically went to a screen that has a green robot icon on it and  say something like don’t turn off while getting to target. I tried to use the power, home and up volume to reset the phone, but got nothing. I took the battery out and can get it to start again, I took it to a technician and he seems to think it has corrupted firmware. He tried to do a factory reset but didn’t succeed, because the phone just shut down when he tried.  Is my phone terminal?

Solution: What you will want to do right now is to check if the problem is battery related by performing the following troubleshooting steps listed below.

  • Clean the charging port of the phone using a can of compressed air. Make sure to remove any dirt or debris stuck in this port.
  • Charge the phone for at least 20 minutes using its wall charger.
  • If there is no charging indicator try using a different charging cord and wall charger. You should also check if the phone can charge from a computer USB port.
  • With the phone still connected to the charger try turning it on.
  • Try getting a new battery.

In case the above steps don’t fix the problem then you will need to bring the phone to a service center and have it checked.

Note 4 Sound Is Muffled On Audio Port

Problem: My headphone jack was messing up the other day. So I bought a new one and installed it. And now I can hear the music parts fine but the singing voices are muffled. I’ve tried to reinstall it and multiple resets, Q tip swipe to clean out the port. I’m confused as to why or how this is happening all of a sudden. Any help is appreciated. Thanks

Solution: You should start the troubleshooting by using a different headphone on your phone as the problem could be caused by the headphone that you are using. You should also try selecting different music tracks to verify if the issue occurs on all tracks.

In case the issue persists you should backup your phone data then do a factory reset. Once the reset is complete check if the issue still occurs. If it does then this could already be a hardware related problem in which case you will need to bring the phone to a service center and have it checked.

  1. I just purchased a refurbished Galaxy Note 4 and it worked perfect for 24 hours and while using an app, my screen went black and there is a flashing blue light on top left corner. I know I have the option to reset completely and reactivating the phone, but I know this issue will happen again. This is not the first time this has happened, I purchased a refurbished galaxy note 4 a year ago and had to return for the same exact issue. I don’t have the money to buy a newer model and love the galaxy note series. Is buying a note 4 a lost cause?
