Problem #1: Solutions to Galaxy Note 4 keeps freezing and randomly rebooting issues | Galaxy Note 4 apps keep crashing

I have a T-Mobile Note 4 that randomly freezes, doesn’t wake up, and frequently reboot itself. It would freeze and later say “so and so app isn’t responding.” I have read a lot from your website and thought I should contribute my experience. I have factory reset multiple times to no avail. However, I recently made a long business trip, and I did observe this:

  1. when the phone is in airplane mode and use the wifi on the airplane, no problem.
  2. when I was in Japan roaming on their 4G network, very bad.
  3. when I was in Taiwan roaming on their 3G network, no problem.
  4. When I was in China roaming on the 2G network, very bad.
  5. When I was in France roaming on 4G network, very bad. So it seemed to me that this problem had something to do with the mobile network radio. After I came back to the States, I went to T-Mobile and got a new SIM card. After installing the new SIM card, the problem persisted. I then proceeded to have another factory reset, now the problem appears 90% gone.

I hope this experience may render some help to others who suffers from the same problem. One easy thing to find out if you have the same problem as me is to switch to airplane mode, then turn on the wifi. If the freezing goes away, then getting a new SIM followed by a factory hard reset would probably help. Thank you, — Ching

Solution: Hi Ching. There a number of reasons why an Android device randomly reboots, freezes, and loses mobile data connectivity so we’re glad that some of the software solutions work for you. It can sometimes be hard to pinpoint where the problem lies so trial-and-error is the best way to go. Thanks for sharing experiences with us. We hope that publishing them will help more Android users.

Problem #2: Galaxy Note 4 rear camera not working | “Warning: server error occurred. Restart camera.” error when using Galaxy Note 4 main camera

Hello! I’m having some issues with my camera. I have a Galaxy Note 4. It was working fine when i got the phone but then for some reason it decided to stop. I thought it was one of those temporary things that only last a day then the next it starts working but in this case it’s not like that. The front camera works fine, but whenever i flip to the back camera, it’s a black screen then it says “Warning: server error occurred. Restart camera.”

I’ve already restarted my device and did everything I could, but nothing worked. I read online that the back camera could’ve possibly dislocated itself but I don’t know how if I hardly ever drop the phone. But if you have any thing that could help me fix this problem it would be great! Thank you! — Mary

Solution: Hi Mary. The only thing that a user can do in this case is to try software solutions. If you’ve already exhausted everything on your end, then you should submit the phone to a repair shop (Samsung or third party) so they can check if there’s a hardware malfunction that’s causing the problem. We suggest that you try the usual dose of software troubleshooting first to see if there’s something that you can do at this time.

The first solution you want to try is refresh the system cache. Sometimes, updates and installation of new app can corrupt the system cache. Making sure that you wipe the cache partition is a must in this case. Here’s how to do that:

  • Power down the phone.
  • Press and hold the following three buttons at the same time:
  • Volume Up key
  • Home key
  • Power key.
  • When the phone vibrates, release the Power and Home key but continue to press and hold the Volume Up key.
  • Continue holding the Volume Up key until the Android System Recovery menu displays and then release. This step may take several seconds.
  • Press the Volume Down key to highlight ‘wipe cache partition.’
  • Press the Power key to select.
  • Press the Volume down key to highlight ‘yes’ then press the Power key to select.
  • When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.
  • Check the rear camera.

If wiping the cache partition won’t fix the issue, the next thing that you want to try is to see if a third party app is causing the problem. This can be done by powering up the phone in safe mode. 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.

  • 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.
  • If the rear camera works fine while safe mode is enabled, that’s a confirmation that one of your third party apps is problematic. Remember, safe mode won’t pinpoint the exact app so you must identify it yourself by uninstalling apps one by one and observing how camera works after each removal.

Finally, if both procedures won’t improve the situation at all, you must do a master reset. This will bring all software settings to default. If an operating system glitch is causing the camera app to malfunction when using the rear camera, master reset should fix it. Here’s how to do it:

  • 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.

Now, if nothing still changes after a factory reset, that’s proof that the problem lies on the hardware department. The camera assembly may be damaged or some unknown hardware malfunction is preventing it from running problem. In this case, the only solution is repair or replacement.

Problem #3: Galaxy Note 4 Edge “not registered on the network” error | Galaxy Note 4 signal dropping when set to WCDMA/3G/4G or auto detect

Hi there. I own a Galaxy Note 4 Edge which i recently bought 2nd hand off eBay. It is currently on an Amaysim 4G unlimited service utilising the Optus network of towers. Amaysim is a reseller of mobile services. I have been experiencing chronic dropouts when set to “WCDMA/3G/4G auto detect” or set to “3G only” settings, getting “not registered on the network” errors when in lower coverage areas.

 It is maddening as i also lose data access and cant text or dial out. The ability to receive incoming communications are also thwarted. It is of course (Murphy’s law) when i am at home in my dead spot unit. When in high coverage areas the phone works perfectly.

I have tried EVERY fix on the internet including a hard reset. Have tried so far:

  • hard/soft reset – removal of battery, wait 30 seconds calling my provider to check settings at their end are
  • swapped out SIM card with friend. My SIM worked fine in their Apple phone. Their SIM still met with same problems I have been experiencing in my handset.
  • new SIM card
  • updating firmware
  • holding down and releasing home, on/off and volume buttons
  • turning flight mode on and off etc
  • changing network settings from WCDMA to 3G only to 2G only

The only mildly successful adjustment i have been able to make is to run it on GSM 2G setting only, which is slow and also due to close in April 2017 (Optus).

Switching to 3G only does not fix the problem either. 2G is not great and still shows errors occasionally but at least it allows me to still have faith that what i have purchased is indeed a mobile phone.

Before anyone suggests returning it for a refund, let me tell you that 1 week after buying it (2nd hand) i dropped it and cracked the screen … so returning it is not an option. It was working fine for the first couple of weeks too. I can’t seem to quite remember when the problems became evident. The dropping of it and also the Android 6.01 software updates are the two most significant events for this phone since i purchased it but i don’t recall either event immediately foreshadowing the network issues. Any advice with regards to this would be very much appreciated.

Some questions:

  • assuming it is a software problem preventing the phone’s antenna from switching between networks/towers consistently, how can i tell which brand of antenna is installed in my model phone?
  • This is the phone’s build no.: MMB29M.N915GXXS1DPH. The phone appears to have originally been branded by our largest carrier in Australia: Telstra as the logo comes up during reboot. It is not locked to Telstra though. Model number: Intel or Realtek which has been suggested to me may be the actual issue. Is it feasible to effectively replace the antenna with an intel one? I can easily manage to complete this task so as long as i can get a new or 2nd hand one cheaply and find a YouTube tutorial. i have a good degree of tech skills which will help to reduce costs.
  • if the above options are not plausible and i have to live with what i have and hope a software fix is released before 2G is turned off, would there be any benefit to purchasing any of your antennae products to improve connectivity? i am also considering buying a mobile signal booster to improve reception at home. Another less than ideal response but in the absence of a good reliable fix becoming known i don’t have any other ideas other than to replace the phone. Did i mention that I am stubborn and don’t give in easily? Thanks in advance – Craig

Solution: Hi Craig. There are three possible reasons for the troubles you’re having:

  1. phone’s radio is defective (perhaps that’s why it may had been sold by the original owner in the first place)
  2. there’s an unknown software/baseband glitch
  3. poor reception in your area

Although we think that the most likely reason for your problem is the third, as you yourself mentioned that the phone works fine when you are in an area with good reception, there’s also a possibility that it may be a combination of any of them. That the phone suffered significant damage after dropping it won’t rule out the possibility that there’s an issue on the hardware department. Like water damage, unnecessary shock to the motherboard can sometimes both lead to short-term and long-term problems.

You can scratch software or baseband issue as factory reset should have eliminated that. If the phone behaves the same after a factory reset and without apps installed, the only possible causes are the first and third.

Now, let’s answer your specific questions.

  1. If you want to know the specific brand and make of the phone’s radio (or antenna as you call it), you need to open up the phone check it on the motherboard itself. We’re pretty sure some websites out there must have a comprehensive list of parts of all Samsung devices. Our blog does not handle hardware troubleshooting and diagnostics though so we don’t normally keep a list like this.
  2. Replacing a particular component is definitely possible but, as we said above, our blog does not address hardware issues so kindly look for other sources of hardware troubleshooting steps.
  3. We don’t sell phone parts so please look for e-commerce sites that do. We will suggest though that you push through with your plans to get a signal booster to improve reception at your place.

Problem #4: Galaxy Note 4 “Phone has stopped” error

Hello! I am using a Samsung Galaxy Note 4 (my father as well) and we both have the “Phone has stopped” error. It only occurs when somebody is calling us, while one app (ex. : Phone, Whatsapp, Gallery, Contacts, Camera, Messages) is open. It does not occur (lets us answer the call) when the phone is locked or we are not using it. My mom is using Samsung Galaxy Note Edge with the exact same software specifications, but luckily she has never has problems. I tried every suggested solution you wrote in your article about this problem and the problem came back. Please help, or let me know who else could help. Thank you! — Ivett

Solution: Hi Ivett. A third party app may be to blame. Boot the phone in safe mode and replicate the issue. A service or app may be creating a conflict with the operating system so observing how calls behave while safe mode is enabled may give you an idea. Refer to the steps above on how to do this procedure.

Problem #5: Galaxy Note 4 freezing, randomly rebooting, and won’t turn on

Hi. My phone has been suddenly freezing and restarting and some times won’t even turn on. I have tried all the steps mentioned in this forum to troubleshoot it and the fix was only temporary. I brought my phone into a Samsung store and the tech helped me do a phone reset. However, it didn’t solve the lagging and restarting issue. Therefore, I purchased a new battery 2 days ago. Phone worked fine and did not reset suddenly anymore, but my phone would suddenly freeze, screen turns black and shuts off completely. Can you please help me? This phone is only 2 years old!! Thanks. — Maggie

Solution: Hi Maggie. Below are the potential solutions that you can try:

 

  1. Wipe the cache partition. This should the first thing that you want to try. Making sure that the system cache is fresh is important in any Android troubleshooting. Refer to the steps above on how to do it.
  2. Recalibrate the battery. The aim of this procedure is to train the operating system how to read battery levels properly. Follow the steps below on how to do it:
    • Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
    • Turn the phone on again and let it turn itself off.
    • Charge the phone without turning it back on.
    • Wait until the battery says it fully charged to 100%
    • Unplug the charger and turn the phone on.
    • If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.
    • Unplug the charger the turn the phone on again.
    • Use the phone until you drain the battery down to 0.
    • Repeat the cycle once.
  3. Power up the phone in safe mode. If the problem persists after calibrating the battery, the next step should be to observe how the device behaves if it’s booted to safe mode. If the problem won’t happen while in safe mode, that’s a sign that a third party app is causing it.
  4. Do another round of factory reset. This is the last step that you can do on your end. The aim of this exercise is to restore all software settings to default so you can observe how the device works when there are no third party apps installed. Let the phone run for 24 hours without installing anything so you’ll notice any difference. If the problem is still present, find a way to have it repaired or replaced as there may be an unknown hardware issue.
