Note 4 Not Turning On After Screen Sleeps
Problem: Note 4 won’t reboot after screen turned off. Works fine as long as I have the screen on, but after it’s been turned off it frequently won’t turn on again (completely unresponsive to all buttons). Pulling the battery for 30 seconds or so usually does the trick. Problem has persisted through 3 factory resets, multiple OEM and 3rd party batteries, and removal of SIM and SD cards.
Solution: If you have already performed a factory reset as well as replaced the battery of your phone which unfortunately doesn’t fix the problem. It’s very likely that could already be caused by a faulty power IC or other internal component. The best way to proceed right now is to have your phone checked at a service center that is capable of performing board level repairs.
Note 4 Shutting Off Randomly
Problem: My Note 4 started shutting off it don’t matter that I have high battery percentages. I tried many things reading here but nothing it be able to work. I did a master reset and without installing any app still doing it. I try to load safe mode but when I press the keys, a warning message show up about installing update. Meaning never get the safe mode option. I change battery still doing it. Wipe cache, still doing it. Running out options. Why I can’t get the safe mode option? What else to do?
Solution: Just like the issue which we have tackled above it looks like this is already caused by an internal component that is failing to work possibly the power IC. Since you have already performed a factory reset and even replaced the battery which doesn’t fix the problem the best thing that you can do right now is to bring the phone to a service center and have it checked.
Note 4 Will Not Power On
Problem: I have a Note 4 that will not turn on. The battery has a charge which I verified with a multimeter. The power button works as well. What other verifications can I make to ensure power is getting to all the necessary components?
Solution: Right now what you can do is to check if the phone has a charging indicator when you charge it. If there is no charging indicator then proceed with the troubleshooting steps listed below.
- Clean the charging port of the phone using a can of compressed air. Make sure that any dirt or debris stuck in this port is removed.
- Try using a different charging cord.
- Try using a different wall charger.
Should the above steps fail to charge the phone then try getting a new battery then check if the phone turns on.
If the issue persists then this could already be a hardware related problem possibly caused by a faulty internal component. If this is the case then you will need to bring the phone to a service center and have it checked.
Note 4 Not Turning On Unresponsive To Charger
Problem: Good morning, i tried to access your page to like but it said unavailable. Let me know when it’s active and i will. Last winter my screen cracked at the gym and has been on sidelines waiting to be fixed. After shopping around batteries plus bulbs had best price. I took phone to repair screen and they said the had to order a new part and solder it in. I picked up phone a couple days later and it worked well all features gps phone speaker etc. over night and the next morning. It charged and worked at full capacity. The next afternoon i placed the phone down and when i picked it up the screen was black, wouldn’t power on, unresponsive when plugged into charger. So i figured the was a short somewhere. Upon bringing it back they let me know the changed the charge port also bc it was “loose” and didn’t “want to be blamed”. They agreed to look it over after trying a new battery. Meanwhile letting me know of the phenomena of note 4 and s4 that were mysteriously dying that they had seen a lot of. They attempted and suggested sending to home office with experts. Supposedly the replaced the buttons associated with powering on and using electronic reader power is flowing but they cannot figure it out. So they are going to refund me. But my phone doesn’t work and i have priceless information which i need back ASAP. Please help, i don’t know what else i can do. What should i do.
Solution: You will not be able to retrieve the data stored in your phone unless you are able to turn it on. Since this is very likely a hardware related problem already this needs to be fixed at a service center. What I can suggest though is to have the display checked again and possibly replaced. Since the phone is getting power when checked using a meter then it’s very likely that you won’t know that the phone is already turned on because of a faulty display.
Another possible factor that can cause this problem is a faulty power IC. Have this checked as well.
Note 4 Randomly Reboots
Problem: It would randomly reboot and at times it would reboot unsuccessfully and come up with an android bot on screen saying reboot was unsuccessful, downloading do not turn off device…. it didn’t do that today but when i locked my phone, it just never turned on again and doesn’t even respond when i try connecting various of chargers
Solution: What you will want to do first in this cas is to make sure that the battery has sufficient charge to turn on the phone by following the troubleshooting steps listed below.
- Clean the charging port of your phone using a can of compressed air. Make sure that any dirt or debris stuck in this port is removed.
- Charge your phone for at least 20 minutes using a different charging cord and wall charger that’s known to work.
- If you get no charging indication from the phone then try charging it from a computer USB port.
If the above steps does not charge the phone then try getting a new battery and see if the phone turns on with this new battery. Before inserting the new battery make sure to remove the microSD card of the phone and old battery then press and hold the power button for at least a minute. This discharges the phone circuit and clears out its RAM.
Should the above steps fail to fix the problem then you will have to bring the phone to a service center and have it checked.
Note 4 Overheating Keeps On Rebooting
Problem: My Note 4 is overheating and rebooting itself over and over. The phone is warm to the touch and I have attempted to remove the battery but this didn’t fix it any. I can not get it to stay off either. When on for a minute or so, it doesn’t truly connect with any wifi. My phone does not have service. Hope you can help soon. Thanks.
Solution: What you will want to do right now is to check if a software glitch is causing the problem by following the troubleshooting steps listed below.
- Try to check if an app you downloaded is causing the problem by starting the phone in Safe Mode. If the issue does not occur in this mode then it is most likely caused by an app you downloaded. Find out what app this is and uninstall it.
- Try wiping the cache partition of your phone from the recovery mode.
- Backup your phone data then do a factory reset.
If the above steps don’t work then perform the additional troubleshooting steps listed below.
- Remove the microSD card of your phone if you have one installed.
- Try using a new battery.
Should the issue persist then I suggest that you bring your phone to a service center and have it checked.
