Galaxy J7 won’t turn on, won’t charge fully to 100%, apps won’t load, other issues

Hello #GalaxyJ7 users! Welcome to our new troubleshooting series that addresses issues regarding the Galaxy J7. We hope that the solutions in this post will help not only the users mentioned here but others that are experiencing similar issues as well. We will be posting more of the same posts in the near future so keep watching.

If you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page.

When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Below are specific topics we’re bringing for you today:

Problem 1: Galaxy J7 getting delayed SMS

My phone is delayed in receiving text messages some times. It’s never too much, at the most half an hour, but it’s still rather inconvenient. I really only text with one person, so I’m not sure if it’s an issue on my end or his. It’s his texts that delay, I don’t think mine do. Sometimes for about half an hour I won’t receive any texts from him, but he is still getting everything I send over that span of time. Then suddenly I get all the texts he’s sent that I hadn’t been getting. Or sometimes it’s just one text that will delay; we’ll be having a conversation then a text he sent 10 minutes ago will finally send. What can I do about this? I’ve restarted my phone plenty, taken the battery out, and it hasn’t helped. Device is a Galaxy J7, carrier I’m pretty sure is Straight talk. — Kaitlyn

Solution: Hi Kaitlyn. You should try to wipe the cache and data of your messaging app. This will address any possible bug that may be in your messaging app. Try to delete the cache first and observe how messaging works for 24 hours. If that won’t work, proceed with Clear Data. Here’s how:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Cache and Clear Data buttons for the application.

There’s really nothing much that you can do on your end to fix an SMS problem. Device troubleshooting is very limited and there’s nothing to change since apparently  SMS function is working. If the issue will continue after clearing the cache and data of the messaging app, contact your carrier for support.

Problem 2: Galaxy J7 uses up all remaining storage space, apps won’t load

My J7 did a software download which completed, installed and optimised all applications. Subsequent to completing all my free storage space started to disappear. As quickly as I deleted apps, images and music, it got used up until all 1.6 GB was used. I could not use any apps. Tried removing the battery and restart. Phone boots to the Samsung name and after a while reboots while chewing up power very quickly. Did a recovery start and erased cache. Did not work. Did a factory reset and that did not work. I am at a loss in terms of what to do next. tried downloading bootloader but it has been saying it is downloading for over an hour. I believe it is hung. — Jefft104

Solution: Hi Jefft104. Like you, there’s no way for us to know what’s going on with your device since there’s not much information you provided. The fact that the phone won’t even do a factory reset is a bad sign though. It can mean that the bootloader may be corrupted, or there’s a software glitch causing system to behave erratically. If your issue is similar to this one, your only option may be to flash the bootloader and firmware. Just ignore the downloading bootloader option as that won’t help. Restart the phone by pressing and holding Power and Volume Down for at least 10 seconds, then boot it back to Odin mode. Try to find a good online guide on how to flash the bootloader and firmware for this particular phone model and see how it goes.

For demonstatation purposes, here are the steps on how to flash a bootloader. Keep in mind that the exact steps may vary on your phone model.

  1. Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
  2. Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
  3. Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
  4. Proceed with the rest of the flashing procedure using the Odin program.
  5. In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
  6. Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
  7. Restart the phone once the procedure is finished.

Problem 3: Galaxy J7 won’t charge fully to 100%

Hello there. For the last few days, my Samsung Galaxy J7 won’t completely charge to 100%. It’s only new since March. I first noticed a couple of nights ago that when I plugged it in, it didn’t do the little bing alert it does to let me know it was charging. But the battery itself had the charge icon so I wasn’t worried. The following morning when I was it was only on 97%. The phone usually fully charges in around 2 hours. I figured I just hit the cable during the night or my toddler unplugged it or something. Then this morning, the same issue. It was only 97% again. I know it’s not the worst of problems but it’s just a little niggling problem that I’m thinking may get worse over time if I don’t fix it Any help would be appreciated 🙂 — Ciara

Solution: Hi Ciara. Try to recalibrate the battery and everything should be fine. Here’s how it’s done:

  1. Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
  2. Turn the phone on again and let it turn itself off.
  3. Charge the phone without turning it back on.
  4. Wait until the battery says it fully charged to 100%
  5. Unplug the charger and turn the phone on.
  6. If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.
  7. Unplug the charger the turn the phone on again.
  8. Use the phone until you drain the battery down to 0.
  9. Repeat the cycle once.

If battery recalibration won’t help, back up your important files using Smart Switch and do a factory reset.

  1. From the Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Backup and reset.
  4. If desired, tap Back up my data to move the slider to ON or OFF.
  5. If desired, tap Restore to move the slider to ON or OFF.
  6. Tap Factory data reset.
  7. Tap Reset device.
  8. If you have screen lock turned on, enter your PIN or password.
  9. Tap Continue.
  10. Tap Delete all.

Problem 4: Galaxy J7 showing green vertical line on the screen

Hey there! Thanks for taking the time to read my problem. I’ve got a Samsung J7 running LineageOS 13 (Android 6.0.1). I’ve got a green line running down my screen about 1 to 2 pixels wide. It does not affect usage of my device in any way. The line shows up even in bootloader and TWRP Recovery. However due to the design of AMOLED screens this line does not appear when black color is being displayed such as when using BlackPlayer EX. I’ve attempted to return to the stock Samsung ROM as well as factory reset and RessurectionRemix Nougat. Is it possible to get this line fixed up? Thanks! — Adarsh

Solution: Hi Adarsh. If this green vertical line appears in Recovery and normal mode, you’re dealing with a hardware issue possibly due to a physical damage. If you want to fix it, have the screen replaced. There’s no amount of software tweak that you can do to solve a bad hardware.

Problem 5: How to recover files from a corrupted SD card in a Galaxy J7

I’ve had SD card installed since purchased, no problems. Think after recent system update this has started, but most recent pics in gallery show up as grey with the exclamation point. I’ve read thru info here and done the following: soft restart, removing battery & SD at least 10 seconds, wiping cache and starting in safe mode. Nothing brings photos back and i don’t know what next step is. Recovery software? Side note, two photos in my gallery show the picture but half of it is solid gray. This is weird to me. — Ticialacollins

Solution: Hi Ticialacollins. The troubleshooting steps you mention here won’t bring your photos back. Yes, you need a recovery software for that, if there’s anything to be recovered at all. Recovery software are mostly proprietary and are only available to companies specializing in digital forensics. If you think those missing files are worth a few hundred dollars, try scouring the web for reputable companies that can help you recover your files.

While searching, make sure not to use your phone or SD card. If possible, turn the phone off and do not remove the SD card. Just leave everything in place to avoid something from overwriting sectors that may still contain relevant information.

Problem 6: Pre-owned Galaxy J7 can’t detect network signal

Respected sir. I bought a second hand Samsung J7 prime, and phone looks good and works good. but i came home and inserted a 4G SIM card and it  doesn’t work. It does not show the network. then i check network setting, but it does not have 4G LTE option in network setting. I checked online and use *#*#4636*#*# and other option too.. but it dosesn’t work. Please reply with solution as soon as possible. Thanks and regards. — Pratik

Solution: Hi Pratik. There are a number of possible reasons why the phone does not detect your network. Here are they:

  • Phone was never network unlocked. Samsung devices, except those built for the global or international market, are usually locked to a certain carrier’s network. For example, although of the same model, some phones are built for AT&T while a similar ones for T-Mobile. The network function of a phone built for AT&T network may not work when you insert a T-Mobile SIM card to it. It must be network unlocked first before you can use a different SIM card to it. You should have asked the previous owner if the phone was network unlocked in the first place.
  • There are things called CDMA and GSM. CDMA and GSM are the two most popular networking technologies being used by most telephone companies around the world. If your J7 was built for a CDMA network like Verizon or Sprint and you try to use it in a GSM network, it may not work. Aside from making sure that it’s network unlocked, you also have to ensure that it can work in a different network type like CDMA or GSM.
  • Phone’s hardware may not be compatible with your current network. Every carrier operates in a particular radio frequency. If your phone’s network chip is designed to work in a different set of radio frequency not being used by your carrier, it will not receive any signal at all.

Due to space limitation in every post, we can’t dwell on more details about these items so our advice to you is to know more about your phone so you’ll know if there’s any incompatibility issue causing the problem. Better still, try to talk to your carrier and see if their technical support team can walk you through some things, especially in checking the details of your phone.

Problem 7: Galaxy J7 won’t turn on

I have a Samsung Galaxy J7. I can’t turn it on or reboot or anything, it’s just a black screen. I’ve tried pulling out the battery, charging it, etc. and nothing has worked. I have even tried plugging it into my computer to charge and nothing comes up on the screen to say that I even plugged it in. Could it be my battery, USB cord, or charger? This happened before when I had an iPhone and they said that I had overcharged it too many times but I’m not sure it’s the same case. Thanks! — J.taylor.4004

Solution: Hi J.taylor.4004. To know what’s the reason for this problem, you need to narrow down the possible causes. Telling us that your phone won’t turn on does not really give us any idea where the issue may lie. You should have included other relevant details that may have led to the issue.

The usual causes of an issue like this includes the following:

  1. defective USB cable and/or charging port (that’s why the phone won’t charge and appears not to power on)
  2. bad battery
  3. damaged charging port
  4. malfunctioning screen assembly (for the black screen issue)
  5. other unknown hardware errors (other serious motherboard problem)

We want you to go over the list above and check each one. We know you can’t directly test the charging port, screen assembly, and the motherboard so if using a different charger/cable and battery won’t fix the problem, send your phone in for repair or replacement.

Problem 8: Galaxy J7 stuck in Samsung logo screen

After a software update was downloaded, I selected install updates. The green Android robot appeared and counted from 1 to 100. Then the Samsung logo kept on flashing with brightness changing from bright to dull for about 3 hours. I did some research then tried to reboot the phone until it eventually gave me option to go to download mode. It was on that screen for about six hours and my phone was heating up. I removed my battery and it returned to the flashing Samsung logo screen. — Wykunjwa

Solution: Hi Wykunjwa. Boot the phone to Recovery mode, then wipe the cache partition first. If nothing will change afterwards, make sure to do a factory reset.

Below are the steps on how to restart your phone to Recovery mode:

  1. Charge the phone for at least 30 minutes.
  2. Make sure the phone is turned off by removing the battery for at least 10 seconds before putting it back in.
  3. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  4. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  5. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  6. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  7. You can either wipe the cache partition or do a factory reset when in this mode.

Problem 9: Sound keeps cutting off when headset is connected to Galaxy J7

Hi. Having sound issues on my Samsung J7. Sound is fine without headphones. With headphones, it cuts out permanently. I can just hear background noise but no speech. I’ve removed the battery, done a factory reset. These haven’t worked. My headphones work fine on other devices. Please help. Thanks. — Arvindaucharaz

Solution: Hi Arvindaucharaz. In a lot of cases, an issue like this is due to a malfunctioning headset port. Try nudging or turning the headset plug to see if you can remedy the situation that way. If that won’t work, try using another headset. Sometimes, a head plug may not fit properly in the port causing poor or no contact at all. If this workaround won’t work though, we’re afraid you have to revert to more drastic solutions like opting for a wireless headset or having the phone replaced entirely.

Problem 10: Galaxy J7 System UI has stopped error

My Samsung Galaxy J7 keeps saying System UI has stopped working everytime I try to recored my phone screen or stream it. it started happening after I accidentaly deleted mobizen for Samsung. Please help me. — Donovan

Solution: The best solution for a System UI-related error is factory reset. If you haven’t tried that, make sure that you do. Here’s how:

  1. Back up data on the internal memory. If you have signed into a Google account on the device, you have activated Anti-theft and will need your Google credentials to finish the Master reset.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  4. When the device logo screen displays, release only the Power key
  5. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  6. Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  7. Press Power button to select.
  8. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  9. Press Power button to select and start the master reset.
  10. When the master reset is complete, ‘Reboot system now’ is highlighted.
  11. Press the Power key to restart the device.

Galaxy Note 4 Randomly Reboots After Lollipop Update

Problem: A week ago, my note 4 had an unfinished software update and every time the network connection drops, my note 4 reboots automatically. I already performed the master reset. Kindly enlighten me, I want my cp to be “normal” again. Thank you very much! — Tess

Follow-up Email: Hi! I have been using my unit for a couple of months now. It had an interrupted software update a week ago, then the following day it started to reboot automatically especially when the network connection is very poor. I have already tried to put it on safe mode, perform master reset, checked network connections, removed the sim card, etc. What else can I do? Help me please bring back my phone to its normal state. Thank you very much! — Tess

Troubleshooting: Hi Tess. If the update process was interrupted, there are two things that could happen; either the firmware was reverted back to previous version or it was successfully installed but with corrupt data. But as you said, you already did a few troubleshooting procedures but the problem remained. I think the new firmware was successfully installed but since the process was interrupted, some of the system data weren’t extracted properly. Inconsistency will often result to reboots, lags, freezes and shut downs.

You need help from your service provider. The firmware needs to be “re-flashed” or reinstalled but the process will be a little complicated plus if you do it yourself, you will void the warranty of your device. So, I’m sorry but there’s nothing much you can do about it but send the phone in for repair.

Galaxy Note 4 Text Messages Delayed

Problem: My text messaging is all jacked up. I send messages and the recipients may get them thirty minutes to an hour later or not at all. I think this may be being caused by the recent update. Any suggestions. — Aspen

Troubleshooting: Try sending an SMS and see if the phone can send it instantly. If it does, then the problem is with the network and not the phone. Otherwise, your suspicion that the recent update caused it may be true. However, the most common cause why a 1kb worth of text can’t be sent instantly is when the phone is getting poor signal reception. So, make sure you are in the area where the phone gets good signal. Then, if you’re using a third-party messaging app, try to uninstall it first and use the stock one. If the problem remained after that, you have no other option but to hard reset your phone:

  1. Turn off the Galaxy Note 4 completely.
  2. Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  3. When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  4. When the Android System Recovery shows on the screen, release the Vol Up key.
  5. Using the Volume Down key, highlight ‘wipe data / factory reset’ and press the Power key to select it.
  6. Now highlight ‘Yes — delete all user data’ using the Vol Down key and press the Power key to begin the reset.
  7. When the master reset is complete, highlight ‘Reboot system now’ and hit the Power key.
  8. The Note 4 will restart but it will be longer than usual. When it reaches the Home screen, then begin your setup.

Galaxy Note 4 Can’t Charge Properly

Problem: Hi. I have a Samsung Note 4 that I am experiencing charging issues with and I am hoping you can help. It all started about 2 weeks ago when the phone just shut down and refused to turn, charge, or do anything. The battery was low, but not at the 10% or less that it usually takes to shut it off. I left the phone alone and let it be for a few hours, then I tried to turn it on. It did turn back on, but wouldn’t charge, gave an error message. I turned phone back off and tried to charge it that way, and it did charge back up to 100%. From that point forward for the next few days, it did seem to loose battery life much quicker than normal, but was charging fine again, phone on or off.   Then it seemed for the next few days that it was all back to normal, had my usaul battery life back and all was good.

Well this weekend, it started acting funny again. When I would plug the phone in (wall charger, with original Samsung cord and base) to charge while it was powered on, it would beep and say Unable to Charge your device. Make sure that you are using a Samsung compatible battery and charger, and that your device is properly connected to the charger. While this error message was on the screen, the LED light would blink red, and as soon as I would click ok on the error box, the phone would begin to charge. However, if I used the side button to make the screen turn off as to save power, it would stop charging again and I would have to hit the menu button to turn the screen back on, and charging would resume again. All this mind you was with an actual Samsung cord. In my car and at work, I have generic chargers, and the charging with those cords worked just fine, with no issues, no error messages, nothing. So I was thinking, fine, I will just make sure I charge my phone at work and in car and no big deal.

Well I tried the Samsung charger at home last night, as my battery was getting low, and it would not charge at all…got the same error message as before, but instead of me being able to hit ok on error box and it begin to charge, it just constantly popped up the error. I tried powering off the phone in hopes that it would charge that way, but no luck. I just figured maybe the cord was shot, and I would just continue to use my car and work charger. Well this morning, now neither of those work either. So at this point, my phone is at 1% and I no way to charge it. I do not know if this is my battery, or if my charging port is bad. I used to have an iPhone 4 and had a similar problem, and replaced the charging port, and that was it, but that was $60. A new battery is as cheap as $10 on ebay, so just looking for some advice before I go broke trying to make my phone work again. Thanks in advance for any help/advice you can give! Thanks, Brooke.

Suggestion: Hey Brooke. I want to get straight with you; you need help from a technician. We appreciate all you effort in providing every detail about your phone and the problem but all of them point to one thing–there’s something wrong with the power or charging IC. Well, at least, that’s is based on my experience. I’ve seen a lot of problems like yours and they all boil down to one problematic chip.

The other possibility is the charging port; either it’s loose or needs re-soldering. Again, the point is you can’t fix the problem yourself especially if you care about your phone’s warranty. I’m sorry I would have to be brief on this but there’s nothing more to say. We appreciate you contacting us, though. Have a nice day, Brooke!

Disable Notifications On Home Lock Screen

Problem: Hello Droid Guy, I wonder if there’s a way to turn off the notifications on the home lock screen? I hate them.

I have a Note 4. Thank you for your response. Regards, Sophia.

Tutorial: Hi Sophia. To disable notifications on the lock screen, go to Settings > Sound & notification. Scroll down until you find “When device is locked” tab. Tap on it and there must be an option that says “Don’t show notifications at all.” That’s it!

New Galaxy Note 4 Reboots Every 2 to 3 Minutes

Problem: Hello, I bought this phone brand new and used it for couple of days, initially it was fine but now it keeps rebooting itself at about every 2 to 3mins. It will suddenly freeze and hang,then reboot itself within few seconds.

I have done the master reset I found in your website but it doesn’t solve d problem. Any way you can help please. Thanks.

Suggestion: If the phone was working fine for a couple of day, then there must have been something you’ve done that triggered the problem, unless the device is problematic out of the box. If the master reset didn’t fix the problem, have it replaced immediately while it’s still within replacement period. I’m sure you don’t want to get stuck with a phone that is defective for years, do you? Of course, you can spend several hours troubleshooting the problem but let’s just be practical here, the easiest way to get a working phone is to have your unit replaced.

Galaxy Note 4 Corrupted After Lollipop Update

Problem: I am writing to you because my new Note 4 that was only 2 weeks old and cost me out of pocket $800 was corrupted when the lollipop update happened. Initially my dial pad was missing the end and send button sporadically. Sometimes you could not end a call because there was no end button and sometimes when dialing a number there was no send button. The screen now freezes up. The Internet is so sluggish its like dial up. I also noticed that the touch sensitivity is horrible. You have to keep tapping and tapping the screen in order to get it to work. My screen is now some ugly puke green color. I called Best Buy here I purchased it and they can do nothing. I called Samsung who could care less and offered if I sent my phone in for 10 -14 days they could work on it or send me a refurbished one. I called my carrier Verizon who was willing to send me a refurbished phone but I declined since my phone was only two weeks old before it was corrupted by this update. I am now paying the remainder of the $800 on a phone that does not work properly. Everyone has let me down and no one has offered me anything to help fix my problem other than sending me a refurbished phone. I’m so disgusted with Samsung especially. Everything in my home is Samsung… tablets computers, TVs refrigerators. This will be the last product from Samsung that I will ever buy and from this point on I will only buy used phones that won’t break my heart or my wallet when these companies rip off innocent people working hard for their dollar like me. I am working with a TV station now to put my story out there so others will know what happen to me. Thanks, Robin.

Troubleshooting: Hi Robin! I am so sorry to hear you’ve been having issues with your phone and no one provided any help. If your positive that the problem started because the firmware was corrupted by the lollipop update, then the best course of action is to master reset the device.

Here’s the thing, if the phone still turns on after the update but some of its features or apps won’t run or open, then some of the data or caches may be the only ones corrupted not the firmware itself. It’s where master reset enters. Honestly, this is the only thing you can do to attempt to fix the problem. If it won’t work, then you need help from your provider or Samsung but it seems like they won’t lift a finger to fix the problem except send you a refurbished unit. Based on experience, this problem can be fixed by simply re-installing the firmware, which needs to be done manually. I’m not sure why it’s so difficult for them.

How To Convince Samsung The Phone Wasn’t Rooted?

Question: Hello, lollipop is creating major issues in our household. We own 2 Galaxy S5’s and 1 Note 4. All are experiencing issues since the update but one in particular is seriously damaged and basically nonfunctional. It started running sluggish after update and progressed over next week to turning on and off and overheating constantly. When it reboots, the first screen that shows up is a black screen that says Samsung Custom with a picture of a lock, then it goes to the red Verizon screen then home page until it shuts down again. I took to best buy, where we bought it new 5 months ago, and they said that black screen means it’s rooted and they won’t touch it! Then we took to Verizon and they said it looked like it might be rooted but can’t be sure till they send it in, if it is, the warranty is void. We did NOT root this phone! We had no knowledge this was even possible and had never heard of such a thing. Is it possible the update caused this? If so, how do we convince Samsung and Verizon it wasn’t us?

Answer: The official update cannot root the firmware, so the answer to your first question is no. Samsung has its way of knowing whether the phone is rooted or not so you better let its technicians take a look at it. That’s the only way you can convince (or not) Samsung that the phone isn’t rooted or not. Or, if it was, it doesn’t matter who did it. What matters is it was rooted.

Galaxy Note 4 Lags/Freezes When Sending SMS & MMS

Problem: Hi Droid Guy, I hope you can help me, I have had a galaxy note 4 for 2.5 months. I am finding that when sending messages (both SMS and MMS) there is a considerable lag or freeze with most. I find that it lags when I press send then if I go to write another message straight away, there is a lag/freeze while the previous message is sending then if I am receiving a message while I am writing a message, again, it freezes. The other issue I have is to back out of the message stream that I am in, it lags/freezes as well, this has become so frustrating and I am unsure how to fix it because basically it is soooo slow. I never had this sort of message issue with my old iphone so I don’t know why I have it with this phone when it is so new. Thanks in advance, Rebecca.

Troubleshooting: Hi Rebecca! Clearing the cache and data of the messaging app will fix this problem, although you may lose all your messages. Just follow these steps and you’ll be fine:

  1. From the Home screen, tap the Apps icon.
  2. Tap Settings and scroll to ‘Applications’ section.
  3. Touch Application Manager.
  4. Swipe left or right to display contents of ‘ALL’ tab.
  5. Scroll to and tap the desired app.
  6. Tap the Clear cache button.
  7. Tap the Clear data button, then OK.

Galaxy Note 4 Shows Settings Has Stopped Error

Problem: Hi,

Your Facebook and website has really great help and is organized so one can find help quickly. I really appreciate that.

Two weeks ago I upgraded to Lollipop on my Verizon Note 4 and now have a new problem that I haven’t found discussed anywhere.

When I click on “Sound and Notification” I get a message “unfortunately settings has stopped” and a revert to the home screen.

I want to remove the notifications on the primary screen. It’s annoying to see Facebook posts when I flip the cover open. However, I can change sound volumes with the hard volume button but can’t change notifications.

I have used your advice and have done battery-out soft reboots, app cache and a wipe cache partition wipe- everything short of a factory re-set. I don’t see the irritating problem seriously enough for that.

I was hoping that maybe the problem with the “sound and notification” choice was Lollipop related and not just mine, and that an update would resolve it eventually But since I don’t see other Lollipop posts about this specific issue, I wonder if it might take a factory re-set after all.

Thanks in advance for your suggestion.


Related Problem: Attaching screen shot of the error…”Unfortunately, Settings has stopped.” I get it when I go into settings and try to open sound and notifications, started happening after lollipop update, any thoughts how I can fix the issue? — Brad

Troubleshooting: Hi Dean. The error message “Unfortunately, Settings has stopped” is a sign that the current firmware your phone is running might have some caches or data that are corrupt. That is why, wiping the cache partition often fixes this issue. In your case, however, master reset is necessary not because it’s a guarantee that the problem will be fixed but because you need to know if the firmware needs to be reflashed or not.

For minor hardware or firmware issues, wiping the cache partition and doing hard reset are often very effective. However, there are just problems that neither of these procedures can resolved especially if the problem is with the firmware itself. I understand why you don’t want to go through all the hassles of resetting your phone but that might be the one thing that might save you from all the trouble.

Galaxy Note 4 Has Poor Reception After Lollipop Update

Problem: Hi my name is Chris and I have a Verizon Galaxy Note 4. After I installed the lollipop update, I don’t get near as good cell service as I did. I use to get 5 bars at my house and now after the update, I have to walk around to get even 2 bars. I’ve tried resetting my phone, cleaning the cache, and deleting multiple apps and still no help. Any suggestions on what I can do to improve my service again? Thank you.

Suggestion: Hi Chris. It sure is not a service issue. The fact is, there were a lot of users that complained about it after the update. While the firmware doesn’t have a bug that affects the capability of the device to receive signal, there could be some data that weren’t properly installed during the update because the only solution is to manually reflash the firmware. With that, you need your provider’s tech to do that for you to make sure warranty remains.

Galaxy Note 4 Can’t Get Out of Safe Mode

Problem: Hi, 2 days ago the message “Safe mode” appears on the Home screen of my Galaxy Note 4 and I don’t have an idea why I have this message appearing on my Home screen. However, yesterday morning I downloaded an application from Play Store and my device is working great. But after a few hours the message showed up on the screen again and I rebooted my phone several times but the message still on the screen. I’m not a tech savvy guy and I don’t know how to fix this annoying issue. Is there any way how can I fix this? Thanks and more power to your site! – Lea

Troubleshooting: Hi Lea. There could be some third-party app messing up with your phone. Usually, the phone would only boot in safe mode without user’s intervention if a third-party app has gone rogue and causing inconsistencies to the phone’s normal processes. The system will reboot in safe mode to temporarily disable the rogue app.

So, if you know which app is causing this problem, go to application manager and just uninstall it. That would surely fix the problem. Yes, it’s simple as that. However, if you don’t know which app is the culprit, you need to wipe the cache partition and if that won’t work, either you uninstall third-party apps one-by-one until the problem is fixed or you backup your data and perform factory reset. Your call!

Galaxy Note 4 Randomly Restarts

Problem: Hi, I have Galaxy Note 4 for almost 7 months now. I don’t have any issues about the performance of my device. However, about 2 days ago my device keeps on restarting without a reason. I removed the battery and placed it back but the issue still happening on my device. I called my provider about the issue but the rep told me to factory reset the device but I don’t to reset my device because I have lots of important files stored from it. Can fix my issue? Thanks and more power! — Emily

Troubleshooting: Hi Emily. First of all, if you have a microSD card mounted on your phone, try accessing some files just to check if the card can still be read by the phone. When the microSD card is damaged or corrupted, the phone will try harder to access it but since the system cannot hack its way into the external storage device, the device will reboot after several minutes especially if it has used a lot of RAM during the process. Removing the microSD card often fixes this problem.

However, if the microSD card is totally fine, there might be an app that’s causing the problem. To isolate the issue, try booting the phone in safe mode and observe closely if it will still restart on its own. If not, then find the app that’s causing all this and uninstall it.

In case the problem isn’t caused by a third-party app, then you really have to reset the phone to its factory settings.
