Problem #1: Galaxy Note 4 faulty battery issue
For quite awhile now, my phone will often lose all battery power when it gets to around 30%… Sometimes it will suddenly go from ~30% to 2% in a second and then die, but often it just flat out turns off.
I reset my phone but this issue continued so I’ve taken it back to my provider, and they gave me a refurbished phone with the same battery (for warranty reasons). This new phone still dies with plenty of battery… They have told me there are no issues with the battery. — Lauren
Solution: Hi Lauren. If this has been the second phone on the same battery, the next logical step to do is try a different battery. The symptoms you described here are consistent with a malfunctioning battery. Troubleshooting your phone after getting a replacement one is pointless unless we have established the fact that there is no battery issue in the first place.
Problem #2: Galaxy Note 4 turns off by itself when trying to load Gmail or uploads pictures
Phone shuts off anytime it wants to while on Gmail or the internet uploading pictures or reading information. 41-80% battery charge and it just shuts down. Not running hot. New battery installed. Same problem.
Nothing is running in the background.
Plug in the charger and phone battery charge reads where it shut off.
Ongoing since Lollipop was installed by Metro PCS. From KitKat operating system. — Tod
Solution: Hi Tod. Not all updates work as intended given the fact that there are millions of possible points of failure in a smartphone. If you think that signs of a problem started occurring after an operating system update, these are the things that you can try:
Wipe the system cache
Also known as cache partition, the system cache is repository of temporary files used by the system to load apps faster. It is supposed to be refreshed after an update but sometimes it simply does not happen. Outdated cache can lead to problems so it is recommended to wipe it clean. Unresponsive apps, freezing, slow performance, among other problems may all be due to poorly organized system cache. Here are the steps to delete your phone’s system cache:
Turn off the Galaxy Note 4 completely.
Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
When the Android System Recovery shows on the screen, release the Volume Up key.
Using the Volume Down key, highlight the option ‘wipe cache partition’ and press the Power key to select it.
When the wiping of the cache partition is finished, highlight ‘Reboot system now’ and hit the power key.
Perform a factory reset
If nothing changes after wiping the cache, doing a factory reset may take care of the trouble. Make sure to keep a copy of personal data as this procedure will erase everything off the phone’s internal storage. If you haven’t done a factory reset before, here are the steps:
Turn off the Galaxy Note 4 completely.
Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
When the Android System Recovery shows on the screen, release the Volume Up key.
Using the Volume Down key, highlight ‘wipe data / factory reset’ and press the Power key to select it.
Now highlight ‘Yes — delete all user data’ using the Volume Down key and press the Power key to begin the reset.
When the master reset is complete, highlight ‘Reboot system now’ and hit the Power key.
The Note 4 will restart but it will be longer than usual. When it reaches the Home screen, then begin your setup.
Try observing the phone for a few hours after doing a factory reset. Do not install any apps during this observation period so you will know if the problem is caused by a malfunctioning app. Keep in mind that a third party application that may not be optimized to work with the most recent operating system on your phone. Because there is no exact way to determine if an app is causing the trouble, doing this procedure after a factory reset is recommended.
Problem #3: Galaxy Note 4 “Set Warranty Bit: kernel” error
The phone suddenly went off when I was using it. Then it kept rebooting, again and again. Always stops at the “Samsung Galaxy Note 4” page.
Rarely, it also runs the Samsung Boot animation and crashes there. Then reboots again.
Sometimes it also shows me the lock screen, I can unlock it at times if I’m quick, but even then, it gets hung within 5 seconds and the screen tears, like, pixelates. Then it reboots.
I’ve tried removing the battery several times. I’m not able to get to the bootloader menu. “Recovery Booting” shows in blue. Then the Android appears, saying “Installing Software Update”, then it freezes again and reboots.
I have no clue why this is happening and what to do next.
I’m running stock Android received over the OTA. I’ve never rooted it. Hardly ever even used it, except for drawing on Sketchbook. I hope I don’t lose my drawings.
And yes, I also tried removing the SD card and rebooting, but the problem still persisted.
Sadly, my drawings weren’t saved to the SD card.
Also, one time it rebooted, it showed the “Set Warranty Bit: kernel” error in yellow.
Please help me. — Vikram
Solution: Hi Vikram. There are only two things that you can do on your end:
try booting in another mode, or
ask for a replacement phone
For the first option, try booting in download mode. Also known as Odin mode, this special runtime environment, allows you to reflash your phone with the original or stock firmware. To boot in safe mode, simply follow these steps:
Power off the phone.
Press and hold Volume Down, Home, and Power buttons.
Wait for the device to reboot in download mode.
Once you know how to boot your Note 4 in download mode, use Google how to reflash a stock ROM or firmware. It is important that you use the correct ROM for your device.
Problem #4: LCD issue on Galaxy Note 4
My phone got wet at the back with infants milk. I was still using it not knowing its already wet at the back then it suddenly shuts down with a vibrate. I turn the power on but it did not. I open the back and wipe it. The next day my sister put it on top of the TV because the surface is hot. Then I use the hair blower at the back of the cellphone. Then I put it under the rice for 2 days. Because I saw in Facebook that rice will absorb water and moist. It turn on since I heard the notifications but there’s no display in the screen. I went to the repair center and told me it was the LCD and will charge me PHP 12,500 pesos. I don’t have that money. How can I use my phone again? It has a sentimental value for me because it was my husband’s gift after I gave birth. Please help. Thank you for your time. God bless. — Allen
Solution: Hi Allen. Water- or liquid-damage is always fatal for electronic devices because there’s a big chance that it can lead to hardware failure. As much as we would like to help you, the repair center that examined your device has more authority to diagnose and recommend a fix than us.
If their examination showed an LCD issue, there’s nothing more than you can do on your end to resolve it. Unless you are a phone technician yourself or knows how to replace phone components, your only remaining option right now is to tap professional help.
Assuming you know how to replace the bad LCD or LCD Digitizer Touch Screen, it will still costs you over half the asking price from the repair center. A brand new Note 4 LCD costs about USD 150 at this time.
Unfortunately, our blog does not provide hardware troubleshooting and diagnostics. Doing software troubleshooting won’t lead us anywhere here, especially that a repair center has already identified which component has failed. If you want to replace the LCD yourself, try using Google for instructions how to do it.
Problem #5: Galaxy Note 4 no longer power on
Hello saw your site and had a lot of great tips. I don’t think this is a common problem but is similar to the not powering up issues. My phone was working fine. I was watching a movie I downloaded from the Google Play Store and about 45 minutes into the movie, the pixels of the movie froze and the entire device was unresponsive. I tried everything and eventually held the power button down for about 30 seconds and the phone shut off. I could not get it to power back on. I tried holding power and volume down or up for over a minute and no luck. I reset the ribbon cables and no luck. The phone was at 90% power to. I tried plugging it in and nothing happened either and tried all of the button combos listed above with it plugged in and still no dice.
Any insight would be great? — Zeke
Solution: Hi Zeke. If your Note 4 does not appear to charge or boot to other modes, consider using another battery. If battery is not the issue, there may be a hardware malfunction behind the trouble.
Problem #6: Rooted Galaxy Note 4 battery issue
Got this new phone a week ago and was dissatisfied with the available memory for apps so I bought a 32GB micro card. Found out that I can’t use it due to “security issues”, so I decided to root the phone using KingoRoot.
As soon as I did, the battery began discharging at the rate of about 1% per minute with a message that said power consumption was higher than the charge rate. This continued even when the phone was plugged in to the wall charger.
I did two factory resets, but the problem continued.
After a few hours of this, it suddenly began charging again. It got up to 59% before I went to bed. When I woke up, it was still at 59%. Over the next few hours of playing games, it only lost 2%. Then, suddenly, it began discharging again, all the way down to 1%.
It has now been at 1% for four hours without being plugged in and has not yet shut off, despite several phone calls, text messages, and games.
I realize that rooting itself could not have affected the battery physically but obviously it messed something up. Do you have any advice?
Thank you for reading. — Michelle
Solution: Hi Michelle. First, you can try to reflash a stock ROM to see the difference. Keep in mind that rooting an Android device is not risk free and can result to unforeseen problems. There’s no telling what happens after a rooting procedure although majority of cases are resolved by simply reflashing a device to stock ROM.
You’re right, rooting won’t affect a battery physically but the software that manages it may be altered in some way.
Third party apps can also cause battery trouble. Try booting in safe mode and observe the phone for a couple days.
