My phone keeps turning off randomly at different times. I recently bought new battery because it’s been more than a year since I have not changed it. In the beginning everything was working fine but then the phone started to shut down randomly. It can shut down at full battery, at half or at any stage without any reason. Now the tricky part is it only comes back alive when you remove the battery from the slot and put it back in again. If you don’t do that, it does not react to the start up button of the phone. It is super annoying and I don’t know what to do… I have been reading about this issue on the internet for a week and nothing seems to help. Would be so glad if you can help me in any way. I’m struggling so much…– Akaki
Solution: Hi Akaki. Random reboot issue can be triggered by a hardware malfunction, poorly-coded apps, or corrupt firmware so you must identify first which of them is behind the trouble.
Calibrate the battery
The first thing that you want to do is make sure that the battery is working fine by calibrating it. Doing so is simple. Simply charge the phone until it’s at 100%. After that, use your phone until the battery reaches 0% percent. To hasten the power drain process, try to play games or watch videos. Once you’ve fully drained the battery, charge it to 100% then drain it once more. Do this charging cycle twice.
Battery calibration is a good way to prevent state-of-charge (SOC) mismatch. You’ll know if SOC is occurring if you’ll notice that your device shows that the battery has already been charged to 100% after only a few minutes of charging. Then once you use your phone, the battery level suddenly drops significantly. SOC can also manifest, in some rare cases, as random reboot issue.
Boot in safe mode
Sometimes, incompatible or problematic apps can interfere with an Android device’s power management system. If you are fond of installing apps, chances are one of them is behind the trouble. To check, simply boot your Note 4 in safe mode. While safe mode is enabled, no third party apps will be allowed to run. This means that if the issue fails to occur, that’s a confirmation that one of your apps is the culprit. Booting in safe mode won’t tell you which of the apps is the cause so you have to use elimination method. Please follow these steps to restart your phone in safe mode:
- Turn off the phone completely.
- Press and hold the Power key and the Volume Down key.
- When the phone starts to boot, release the Power key but continue holding the Volume Down key until the phone finished restarting.
- Safe mode will be display at the lower left corner; you may release the Volume Down key now.
Do a factory reset
Random reboot problem can also be caused by an operating system glitch that may have developed after an update. If nothing seems to work after battery calibration or while the phone is in safe mode, consider wiping the device clean. What you want to achieve is to see whether there’s a difference after a factory reset or not. Please refer to the steps below on how to do a factory reset.
By the way, make sure that you don’t install any apps right away after a factory reset. Allow your phone to run for at least 24 hours without any third party apps so you can check if random reboot continues to occur.
Replace the battery or have the phone checked
If the problem remains after doing the software troubleshooting above, you can safely assume that a hardware error is the cause. Try using another battery to see if that’s the problem. Otherwise, call Samsung for repair or replacement.
Hello. I am having some serious problem with my Note 4 and I’m hoping you can help. Problems:
- constant lagging, action delay after button press in 5 – 10 seconds if it even works at all.
- Screen freezing constantly followed by reboots.
- A lot of random reboots.
Once today I got some kernel error message.
I used the three button press to force phone into reboot and it started back up ok.
All of these problems seemed to start after I replaced the battery although some were there before. I don’t however think this is the reason as my wife also changed her battery and has no issues.
I’ve tried the wipe partition several times and it made little difference.
I backed up my phone with Samsung Kies and then did a factory reset. No difference.
Also on a side note, when I restored my phone with the Kies backup my private folder files are gone.
I know they are still there somewhere as I can see the private folder on laptop screen and how much data is in it. I can’t access it though . Any idea?
Look forward to your responses if any.
Thanks a lot. — Emmet
Solution: Hi Emmet. Your issues may be a bit different from Akaki above but the solutions that we can give remain that same. Keep in mind that factory reset may or may not directly resolve the issue if the reason for the problem is one of your apps. Try to do another round of factory reset and observe the phone for 24 hours without installing any app. This way you’ll know if the problem is hardware-related or not.
If your issue is due to a hardware error, you will most likely end up getting a replacement device. Diagnosing a hardware problem is tricky and can sometimes be inconclusive. This is the main reason why Samsung or carriers will right away recommend a replacement instead of spending time and effort in checking every potential failing component.
For the Kies question, the answer lies on the file format of the file or folder involved. Kies functionality is straightforward –what you see is what you get. If this program can’t view your private folder, then it’s unable to access or move it. You have to manually copy the said private folder to another device or to your laptop.
Hi there. I have bought a Note 4 Verizon SMN910V to use it on T-Mobile network. I called in advance Verizon to ask if that model would be compatible with T-Mobile and I been told the phone would work in 3g or H+ since it is original from that carrier. In the past i had many Verizon phones like iPhones and LG3-4 from Verizon working on T-Mobile without a problem.
Now i just put my SIM card on this Note 4 and i have no signal at all. The signal bar is empty and there is a message saying searching for service.
i tried changing mobile network to Global-LTE and nothing.
i called Verizon again and the phone is clean, not blacklisted, no financial payments due, nothing.
Any idea? — Donovan
Solution: Hi Donovan. There are two cellular technologies in the United States — CDMA and GSM. Verizon is using CDMA while T-Mobile is on GSM. These two technologies won’t work with each other generally so there are a few things to consider to make sure that your Note 4 will work on T-Mobile’s network.
Make sure that your phone is unlocked by Verizon
You may have done this already but we can’t see you mentioning that your Note 4 has been unlocked by Verizon. The phone may be free from any remain financial dues from Verizon but you still need to network unlock it. Verizon claims that most of its 4G LTE Verizon phones are already unlocked and can be readily used on other networks but calling them again regarding is may be necessary.
Check if your phone’s radios is compatible with T-Mobile’s frequencies
These are the frequencies that T-Mobile is using right now:
- 2G: 1900MHz frequency (Band 2)
- 3G: 1700MHz and 2100MHz frequencies (Band 4)
- 4G (LTE): 700Mhz frequency (Band 12), 1700 MHz and 2100MHz frequencies (Band 4), 1900MHz frequency (Band 2)
Verizon’s Galaxy Note 4 version (SM-N910V model) is compatible with T-Mobile’s frequencies but it won’t hurt if you double check this aspect.
Ensure that your area is covered by T-Mobile services
This may seem obvious but some users may easily overlook this fact. Try to insert your T-Mobile SIM card to another cellphone to see if you’re location is covered by T-Mobile.
If all else fails, be sure to contact T-Mobile so they can give you direct assistance.
I have a Samsung Galaxy Note 4 4G LTE. My carrier is Virgin Mobile.
I have had this phone for a long time and have only ever had minor problems with it until this point. Yesterday i noticed the battery was at about 30%, so i plugged it in and let it be for a while. When i went back later, the phone was off. When i tried to turn it on, it simply lit the screen and showed the SAMSUNG logo before turning off again. I figured that i must not have plugged it in all the way, so i re plugged it in, but it just lit up the charging screen for about a second, not even long enough to load the battery image to show how much battery is left.
I tried with four different chargers and multiple outlets and it’s just doing the same thing. I’ve discovered the screen also lights up for a moment when i put the battery into the phone. I tried to do the reset method where you hold the power and the volume down button, and the screen lit up with the message but then immediately went black again.
Could this be a battery issue or is it my phone? i have 5 years worth of memories stored on that phone and i really hope i can access them, even if the phone can no longer be the one i use. — Ariana
Solution: Hi Ariana. We highly suggest that you try another battery first before doing anything drastic. Like you, we can’t say for sure what the problem may be unless you do something. A phone that doesn’t respond to any hardware button combination (to boot in different modes) is most likely suffering from hardware failure. If a new battery won’t resolve the issue, you’re out of luck. There will be no way to recover your personal data from that phone.
And as a reminder, always create a backup of your important files in the future. Digital devices are not perfect and can run into trouble any time. File recovery does not work if a storage device like the Nand chip in your Note 4 is damaged, or becomes inaccessible because the motherboard it is attached to is no longer working.
My phone took a quick dip in the toilet last night (probably 2 seconds). I immediately shut it off, and removed battery and wiped it dry and put it in a bag of rice. (I didn’t take out the SIM card until this morning since I had issues getting it out).
Anyways, this morning, it seemed to be working fine. except the clock wasn’t accurate (which I reset on my settings and it works now). and I am able to receive but not send text messages.
I restarted, turned on and off many times but still having the same issue. It looks like my messages are going through to the other party but it’s not actually showing in my text history so I don’t actually know if my text went through or not. ( I just know that they go through if the other party notifies me that they received a text from me.) I am able to receive text messages without any problems.
Please advise. Thank you so much! — Sara
Solution: Hi Sara. We can’t see the logic of water damage causing a particular app to not work properly so the texting issue may only be a coincidence. Try to wipe the cache and data of the messaging app you’re using to see if that will make any difference.
- Go to Settings.
- Proceed to Applications.
- Select Manage Applications.
- Tap the All tab.
- Choose the name of the app.
- From there, you will see the Clear Cache and Clear Data buttons.
Keep in mind that tapping on the Clear Data button will erase your SMS and MMS. Try to create a copy of important files before you proceed.
If the issue remains afterwards, make sure that you check that your phone has the correct Message Center number.
You can also try inserting your SIM card to another device (if you have a GSM-based phone) to see if there’s an account problem preventing you from sending text.
If the issue continues, we don’t think doing a factory reset will be an issue. For reference, please follow these steps on how to do that:
- 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.
Doing a factory reset is the last resort and it’s aimed at checking whether there’s a firmware glitch behind the trouble (though we highly doubt it). Don’t forget to backup your files before you proceed with this procedure.
Now, if nothing seem to work at all, don’t hesitate to ask your service provider for answers.
