Hi guys. Thanks in advance for reading about my issue. Basically, I have a Samsung Note 4 in white. Originally it was locked to Vodafone but i had it unlocked (via an eBay unlock code)… have been using it for a couple of months after it was unlocked and it’s a brilliant phone and everything worked fine. I had the Note 3 before this.
Yesterday, whilst i was on the phone, the phone just turned off suddenly. It had some battery left so I was shocked to when it turned off.
Since then, I have tried everything… no responses at all – no vibration, no LED lights…!
Tried different chargers, connecting to my laptop, soft reset, recovery mode….. you name it!! ABSOLOTELY NOTHING HAS HELPED! 🙁
So basically the phone is dead but yesterday was working 100% fine. I don’t know what’s the issue. Someone please help me. — Riz
Solution: Hi Riz. If there’s one important troubleshooting step that you did not mention, it is battery replacement. If you’ve been using your Note 4 for over a year now, there’s a chance that the battery may have simply lost its ability to hold a charge. Lithium-based batteries like the one on your handset gradually loses capacity everytime you recharge it. After some time, the battery will just die a natural death due to regular charging cycles even if you take care of it.
A Lithium-ion battery works by moving Lithium ions between a cathode and an anode. During a charging session, the ions stick to the Carbon (graphite) anode, then they move back to the Lithium-Cobalt Oxide cathode when you discharge the battery or when you when your phone. The process of ions moving back and forth between the electrodes is called “cycling”.
The problem lies in the inefficiency of the cycling process. Every time you charge the battery, a film of Lithium atoms are collected permanently in the anode, resulting to capacity loss. The more Lithium ions bonded in the anode for good, the less the charge becomes. If the ions can’t move between the electrodes, no charge is generated leading to failure to deliver power. Do the charging cycle everyday and the battery will lose significant charge in over a year.
While the decline in capacity is gradual, it will not cause the battery to fail entirely though. This kind of situation can be caused by a different thing called electrolyte oxidation. Like the anode accumulating a film of ions during and after every cycle, the cathode can develop a similar layer due to battery overheating or higher voltage. Exposing the battery to high voltage or heat can create a layer of ions around the cathode which can lead to sudden capacity loss — one which is easily noticeable compared to the gradual decline because of regular charging cycle.
The problem is manifested in the phone being unable to boot up normally because the battery no longer deliver power. Unfortunately, electrolyte oxidation on the cathode is permanent and can cause irreversible damage. Your best bet is to have the battery replaced. Thankfully, you have a Note 4 so battery replacement can be done easily.
I can’t use my screen, but I know I have a version of Lollipop installed. The screen has the following issues:
1.) won’t respond to touch
2.) white, vertical, lines of varying width running the entire length of the screen.
3.) black, inky, splotches on screen that have continued to appear / grow since last night when this issue started.
I dropped it a few times recently, but with no immediately noticeable issues.
Was out a party last night and noticed it was getting hit in my pocket, so then I removed it and placed it somewhere safe – I checked it later, and it had these issues. — Kyle
Solution: Hi Kyle. If the phone appears to power on normally as it probably vibrates and make a sound when restarting it but the screen remains unresponsive, that’s a clear sign that you have a hardware issue. The drop may have damaged the display assembly or some of its components causing it to appear to be unresponsive and showing those lines.
If you are confident of your electronics skills, you can try the DIY (do-it-yourself) tutorials that some sites provide on how to replace the display assembly. Keep in mind though that screen replacement process is a bit tricky and can result to other hardware issues if not done correctly.
We highly recommend though that you let a professional do it for you. Better still, call Samsung so they can repair or replace the handset in a matter of days.
Hi. I have been having problems with my Samsung Galaxy Note 4. It is constantly freezing, lagging, rebooting. I had taken it over to the Samsung repair center and they said that they rebuilt my software and check out all the hardware and everything passed its tests. However right after I left there I had more problems.
I use the phone for 3 days without my micro SD card installed as requested. I also use the phone as a game without installing anything. The problems continued although they were less frequent. Now I have put back in my micro SD card and reinstalled my backup but just for data. I still have not installed any third-party applications.
The issues with the phone seem to be getting worse. I am lucky if I can use the phone sometimes for 2 minutes before it freezes and I have to pull the battery to reset it.
Also sometimes when pulling the battery for reset the phone will boot up into download mode saying that it can’t boot up or can’t find a partition. Sometimes I will put in the battery and it’ll vibrate like it’s turning on but nothing happens. Sometimes I will put in the battery and hit the power button and nothing happens at all so I have to remove the battery and keep it out for a little while before it’ll turn on again. I am not certain if this is a software issue or if this might be still a hardware issue even though Samsung stated everything was fine.
I hope that you might be able to offer some helpful information so I can continue to improve on this phone otherwise I’m afraid I may have to replace it.
Thank you very much for your help. — Ranon
Solution: Hi Ranon. If Samsung’s diagnostics were not able to identify the reason for the lag issue, then most probably we won’t be of little to no help to you. The best that we can do in this case is to tell a user to do the basic software troubleshooting like wiping system and app caches, doing a factory reset, booting in safe mode, or at most, flashing a new ROM. If nothing of these procedures won’t help, we can assume that the issue lies something deeper, which unfortunately is beyond an average user’s ability to identify and resolve.
Lag issues that can’t be fixed by simple troubleshooting can be indicative of a processor malfunction, a coding glitch deep inside the operating system, some other hardware components that no longer works normally, or a combination of these three. In order to do a task like loading a game, all the necessary hardware like the processor (CPU), Random Access Memory (RAM), Graphics Processing Unit (GPU), Signal Processor, Modem, etc., are supposed to work in harmony to create a smooth rendering on the display. Visible lag can happen if any of the hardware components fail to work as expected. In other words, you may notice lag if your device is unable to handle a task/s. Keep in mind that your device manages multiple tasks or threads at the same time.
If a CPU, for example, has been damaged for some reason, it may not be able to process multiple tasks at the same time. This situation can create a chain of problems to other components as well as they will not get the expected result from the processor, causing further lag and stutter.
The thing is, this problem is rare. As mentioned, lag issues that refuse to be fixed by software troubleshooting means that there’s probably a hardware-related cause. We suggest that you invest in phone replacement rather than attempt to have it fixed.
Hi..i have a Samsung Galaxy Note 4 N910F running on Android 5.1.1. Ever since i bought this phone, I’ve been facing this problem. I don’t know if this problem was there when the phone was running on KitKat as i updated it immediately after i bought it.
The problem is that after sending a few text messages, the phone stops sending further messages. At that point the phone doesn’t make any call or receive any call. Mobile data also cannot be switched on. In short, all network related functions stop. The signal bar shows full signals but wi-fi, applications and other functions keep on working fine. When i restart the phone, it starts sending text messages again and receives and makes calls again but again after sending a few text messages, the phone fails to send further messages.
I’ve tried doing a factory reset but of no use. If i don’t send text messages the phone, works perfectly fine for days; mobile data, calls everything works fine but the moment i send a few messages the problem starts again. Kindly guide me about it.. I am really worried about this problem. Thankyou. — Taimoor
Solution: Hi Taimoor. The problem may be caused by a third party app you installed. Doing a factory reset then re-installing the same set of apps afterwards is counterproductive. You can either try to do another round of factory reset and observe the phone for a few days without installing anything, or you can boot the phone in safe mode and observe it for a few hours. Either way should help you determine if one of your apps is to blame. Booting Galaxy Note 4 in safe mode will temporarily disable all third-party or download apps leaving pre-installed ones and core services running. This procedure can help you determine which of your apps is causing a problem. For reference, here are the steps to boot your Note 4 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 Volüme 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.
Insurance company sent me a new NOTE 4 replacement. had done a back up. I reinstalled using Kies3. Everything works fine except messaging. I read the info on here about lagging texts. My texts don’t load immediately. And to delete any messages take 1-10 minutes. It’s frustrating.
I followed instructions about application manager and clearing Cache and data HOWEVER my MESSAGING App doesn’t appear in the downloaded or SD or running but appears in the “all” column. I did the data clear and still a problem.
All the other apps show up. I did install Textra as a 3rd party app. It worked great for one day and now, when i try to send im getting numerous FAIL message and try again.. SO i switched back to the default android Messaging. Any thoughts? — Michael
Solution: Hi Michael. Texting problems like the one you are experiencing can be caused by device-specific issue or wireless carrier problem. Your first task is to identify if it’s related to your phone by doing some software troubleshooting. You can start by either wiping the cache partition or going directly to factory reset. The former ensures that the system cache is fresh to minimize app-related problems, while the latter restores all app and system settings back to default. Both of them can be done in Recovery Mode. Here’s how they’re done:
- 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’ or ‘wipe cache partition’ and press the Power key to select it.
- Now highlight ‘Yes — delete all user data’ (for factory reset) 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.
Any of these procedures should help you fix the problem. If nothing works though, make sure to contact your wireless carrier to see if the issue is from their side.
