How to fix a Galaxy Note 4 that won’t stay on when not connected to a charger, other issues

Welcome to another #GalaxyNote4 post for the day! We hope that you’ll find this material a good source of useful tips about Note 4. We’ll be writing more of the same in the coming weeks so for those who are yet to see their issues published, 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 Note 4 won’t install updates

Hi. I have just attempted to install latest software update from Samsung but install will not complete 100%. I am getting a screen appear giving me various options Reboot system now, Reboot to bootloader, Apply update from adb, Apply update from sd card, Wipe data/factory reset, Wipe cache partition, Mount/system View recovery logs, Power off. I have already tried wipe cache partition and reboot options and reboot but nothing changes. I am anxious as I do not want to lose personal files. Any ideas Thanks p.s: The phone is a Note 4. — Martin

Solution: Hi Martin. Can you select “Power off” and restart the phone to normal mode? If you can, simply turn the phone off and ignore the update notification once you restart the device.

If you can’t select Power off for some reason, you have no other choice but to do wipe data/factory reset. An issue like this is usually fixed with a factory reset so this is the only option for you right now.

Problem 2: Galaxy Note 4 stopped charging after it was accidentally dropped

Hi. My Galaxy Note 4 phone was just charging no problem at all in the afternoon. This evening, my daughter dropped on the ground and the back battery cover fell and realize tonight the charging no longer work. I tried turning off, pull out and plug again it did not work. I also tried using a portable charger, it was charging for one split second and it’s not charging again. Please kindly assist me with this issue. Many thanks. — Chengkaryan

Solution: Hi Chengkaryan. A charging problem like this is most likely caused by bad hardware, like a possible malfunctioning charging port, so there’s no amount of software tweak that you can do on your end to fix it. Try to use another charger and USB cable to see if that will fix it. If nothing will change and if the phone can still power on, you should try to do a factory reset. This will allow you to eliminate possible software bug that may be causing the problem. Here’s how to do it:

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  2. Turn off the Galaxy Note 4 completely.
  3. Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  4. When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  5. When the Android System Recovery shows on the screen, release the Vol Up key.
  6. Using the Volume Down key, highlight ‘wipe data / factory reset’ and press the Power key to select it.
  7. Now highlight ‘Yes — delete all user data’ using the Vol Down key and press the Power key to begin the reset.
  8. When the master reset is complete, highlight ‘Reboot system now’ and hit the Power key.
  9. The Note 4 will restart but it will be longer than usual. When it reaches the Home screen, then begin your setup.

Now, as we said earlier, the main reason for this problem is bad hardware so if factory reset won’t fix your problem at all, you need to send the phone in so it can be repaired or replaced.

Problem 3: Galaxy Note 4 keeps shutting down on its own, won’t power back on

My Note 4, at first experienced random quits and shut offs. I followed some trouble shooting advice of removing the SD card to see if that would alleviate the problem but it still shut off. Usually I had to take out the battery before attempting to restart but now the phone wont power up at all. Do I need a new phone? I’m trying to hold out for the Note 8 in August. Please help. I can’t determine the OS because the phone will not power up. — Klee4.1.kl

Solution: Hi Klee4.1.kl. The first thing that you want to do right now is to check if you’ll still be able to turn the phone back on to other modes. If you can, there’s a chance that you can still fix the problem with a software solution. Below are the steps on how to turn the phone back on to other modes and the respective follow-up troubleshooting that you can do afterwards.

Boot in Recovery mode:

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

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to do it.

Boot in safe mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

If your phone remains dead or won’t boot to any of the boot modes above, the only other step that you can do is to get a new battery. One of the usual reasons for random reboot or complete failure to boot issues is bad battery. If you’re lucky and the issue lies on the battery only, getting a new one should be an easy fix.

If the problem stays even with a new battery though, send it in for repair or replacement.

Problem 4: Galaxy Note 4 can’t share via SMS

Everytime I try to share anything through a text, I get a pop up to choose existing contact or new contact. I choose existing and it freezes. I can’t choose a person or close it or anything. I have to wait for it so pop up with “Contacts isn’t responding, Do you want to close it?” If I hit wait, it stays frozen. If I choose close, it closes and goes back to home screen. So I can share anything through texts! HELP!!!! — Mlfarque

Solution: Hi Mlfarque. To fix the problem, clear the cache and data of both the Contacts app and Messaging app. 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 Data and Clear Cache buttons for the application.

Note: Hitting the Clear Data button will erase your messages and contacts so make sure to back them up using Smart Switch before proceeding.

Now, if the problem remains after wiping the cache and data of both apps, you must

contact your carrier so they can help you with it.

Problem 5: Galaxy Note 4 keeps turning off after an update

Over the past 3 weeks, possibly after an upgrade, my cell phone turns off intermittently. I have received messages

  1. “Normal Boot MMC Read Failed Error”), and
  2. the “Downloading” do not turn off target “error.

I have replaced the battery with a new original Samsung battery and have already done a hard reset. The problem comes back after a few hours and it us frustrating. Is there anything else I can do? Regards. — Mike

Solution: Hi Mike. Try observing the phone while it’s on safe mode and see what happens. It’s possible that the problem is due to an incompatible or buggy app. If it’s not an app problem, you will most likely end up with a replacement phone because there’s no other way to know what is causing the issue.

If you want to try flashing, we recommend that you do the bootloader first before the firmware. Below are the general steps on how to flash a bootloader. The exact steps may vary on your phone model so try to do some research before doing the actual procedure. The steps below are meant to give you an idea on how flashing is done:

  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 6: Galaxy Note 4 “could not do normal boot …” error

My sister’s phone has been acting up the last couple of days. Lag, turning off by itself. Then today it did up upgrade on her phone. And now there is an error message. Could not do normal boot. ddi mc_ read failed Product name current binary samsung offical system status custom recactivation lock off knox warranty void. Qualcomm secureboot enable CSB AP swev st t1 a1 a1 p1 secure download enabled udc start. And I removed the battery and it won’t do anything. The screen is frozen.         — Rose

Solution: Hi Rose. Please refer to our suggestion for Klee4.1.kl above. Remember, if the phone becomes totally dead, your only option would either be repair or replacement.

Problem 7: Galaxy Note 4 screen won’t turn on when pressing Power or Home button, screen discoloration

Samsung Galaxy Note 4. Problems started a week ago.

  1. Phone screen will not turn on when pressing home button or power button. Took out battery to restart but two full tries for screen to stay on and phone work fine for about 12 hours. This happens every day so I have to take battery out everyday. Phone screen will turn on if I receive a call which seems to wake up screen and works properly for awhile.
  2. Also, started noticing when screen is about to go black due to inactivity, it flicks green and sometimes gray.
  3. Restarted phone, and the Samsung logo was yellow instead of white then it went dead. Had to take battery again to restart.

Phone has all current updates and hasn’t been dropped recently. The unresponsive screen also happen on safe mode. Any ideas to save this phone? It has only been 18 months. Thanks. — Patricia

Solution: Hi Patricia. We witnessed this issue happening on devices with malfunctioning or old battery. At 18 months, your phone’s battery can be considered ripe so if you can, try to get a new battery so you can compare how the device works with it.

You can, of course, do the basic software troubleshooting like the cache partition wipe and factory reset to eliminate possible software causes. If nothing will change after changing the battery and factory reset, you can assume that there’s a more serious hardware problem involved. In that case, consider repair or replacement.

Problem 8: Galaxy Note 4 stuck in boot loop after an update

After an update yesterday, my Samsung Galaxy Note 4 went into a repeating boot cycle. I couldn’t even start it in safe mode. After deciding to perform a factory reset I could finally get it to turn on. But now I’m having huge issues with the internal storage where from a restart it tells me I’ve used 7GB out of 16GB, but within 5 minutes it has gone up to nearly 9GB and i wasn’t even using the phone! Within an hour or so it fills right up to the 16GB causing everything to shut down, forcing me to restart the device. When it starts back up it has gone back down to 7GB and begins building back up again. I have screenshots of this happening over a 5 minute period and also a screenshot of the device details. If any more info is needed feel free to ask and thank you so much for your time. — Ross

Solution: Hi Ross. We think we’ve heard of this issue before on a different device but we couldn’t find the right article. We thought then that it was an isolated case but since you’re now experiencing it as well, this may not be isolated but rather a firmware coding issue. Since a factory reset won’t help in this case, the best option that you can do now is to attempt a manual installation of the previous stock firmware via flashing. We know it’s not an ideal solution but it’s an effective one if you wish to continue to use your phone. If you haven’t heard about flashing, try to do some Google search about it and make sure to use a good guide if you decide to flash your phone.

Once you’ve flashed the older firmware, probably Android Marshmallow, contact your carrier and let them know about the issue. We assume that you only update via OTA (over-the-air) but if not, you should talk to the developer of the firmware you’re using or get help from other users who may also be using the same firmware.

Problem 9: How to fix a Galaxy Note 4 that won’t stay on when not connected to a charger

Hello, I had a very big problem with my device that keeps restarting whenever I won’t charge it. It shows green flickers and restarts automatically, this problem frustrates me very much. I bought this phone like 3 years ago and this problem occur one year ago. I tried all of the suggestions in the internet, I “factory reset,” I “clear caches” all of my apps and I even upgrade my phone to “Marshmallow 6.0.1.” The previous version of my phone is like 5.0 plus and once I upgrade to “Marshmallow 6.0.1,” the problem is getting worse. But one thing that prevents my phone from restarting is by charging it. Uggghh, should I charge my phone every time when I use it???

The subscriber said that the technician CHANGE THE MOTHERBOARD??? Really, this is problem of my phone that keeps restarting automatically? I don’t want to cost money!!! And my question is, IS THERE ANY SUGGESTIONS TO FIX MY PROBLEM WITHOUT COSTING MONEY? Suggestions I’ve tried: * Factory reset * Clear caches * Software update. — Nathanael

Solution: Hi Nathanael. Sometimes, random reboot issue, like the one happening on your phone, can be caused by an overheating CPU. Try to slow down the CPU of the device by setting it to Power Saving Mode. Here’s how:

  1. Touch Apps
  2. Tap Settings.
  3. Tap Power saving.
  4. Tap the Power saving mode slider to enable it.

If enabling Power saving mode won’t work, replace the battery. This should help fix the problem. If the issue remains though, it’s probably the time to consider getting a new phone.

Problem 10: Galaxy Note 4 has no signal reception after motherboard replacement

I have a Samsung Galaxy Note 4 LTE. Originally Unlocked. While my phone was under warranty (but now expired) I sent it to Samsung for repair under warranty: The phone USB port was very difficult to engage. They did not fix it stating it was ok; they returned phone without any repair. Recently, inside the USB port the metal contact became loose from its seating place (left side of usb I think it is for DATA). I could not insert USB charger anymore. I got from local phone shop a USB PORT Flexi circuit board Ref: SM 9005, REV 1.1, LTE, also it has the Antenna & Mic on it. But did not work. the phone was heating up when on charge and NO signal. I replaced my old USB port but there is NO reception. the rest of the phone functions properly. When I am outside I get very little reception on & off, but no signal indoors, states emergency calls.

Also, when outside near a transmitter I get full signal. I purchased another USB PORT Flexi circuit board Ref: SM 9005, REV 1.2, SI 1414, LTE, This still has no reception indoors when outside I get very little reception on & off. But the phone is charging properly. My phone is working 100% with my computer, kies 3 and others software, no problems. I replaced a new antenna wire but still no reception. I have tried other SIM cards still NO signal indoors. did factory reset many times. PLEASE CAN YOU ADVICE ME WHAT COULD BE THE PROBLEM. — B.miah

Solution: Hi B.miah. We can only give you an accurate answer if we can physically check the phone ourselves. We also don’t know if the circuit board you’re using is actually working properly. It’s common knowledge that there are a lot of online merchants that sell defective motherboards to unsuspecting buyers. The problem is, there’s no way to know if a purchased unit is working or not. The only time that you’ll know if it’s problematic is when there are problems that show after a repair. If the rest of your phone’s functionalities are working except the signal reception, the most likely problem must lie on the device’s modem. Sometimes, installing an update can fix network problems after repair so make sure that you do that too. If that won’t work, you should consider letting a professional check the device for you.

Galaxy S7 keeps restarting after using it under water, won’t read SD cards after an update, other issues

Hello Android community! Here’s another #GalaxyS7 post for you and we hope that you’ll find it useful. We are publishing more of the same posts in the coming days 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 S7 won’t read SD cards after an update

So around a week or so ago, I upgraded my phone via a notification that popped up in the notification area. Afterwards, I started getting this unsupported SD card message. Seems like I’ve seen this happen in the past with the last OS version and would simply reformat the card since it seemed to be the easiest way to get things back to normal. Now, however, the phone will not format it. It tries and then delivers the message “command ‘7 volume partition disk: 179,0 public’ failed with ‘400 7 Command failed.” Every time I attempt another reformat, the first and last number (7 above) increment by one. The first logical conclusion that I came to was that the SD card is corrupt or bad. So I took it out and with a reader, attempted to access it with my Windows laptop. I could browse the card with no problem so I copied the data and then reformatted the card to FAT32. After reinserting into the phone, I get the same unsupported SD card message and so I attempted to format again. I get a progress bar that’s prepopulated at 20%, then the message above pops up. I, again, thought maybe it was the SD card so I tried another. Same thing….tried another….same thing. I’ve tried multiple cards no with no difference.  The first SD card is a Transcend 32GB Class 10 card and the other cards I’ve tried are all Samsung 8GB Class 10. The phone is running Android version 7.0. I have attempted the following with no change:

  • factory reset,
  • wiped the cache,
  • booted into safe mode, and reformatting the card using both Windows DiskManagement (both quick and slow method) and GParted.

A Google search returns quite a few hits related to this type of error message but no apparent resolution or cause. Everything is pointing back to the phone as the culprit, but I’m just not sure if it’s software in nature or hardware. My gut says it’s software since it started happening after the last upgrade and the fact that it appears to be manufacturer agnostic, meaning I’ve seen Sony users, Motorola users, HTC users, etc…. having the exact same problem.

Anyway, I’m hoping it’s a software as that would lead me to believe there is a possible fix for it. Any ideas? — Billyrwise

Solution: Hi Billyrwise. There’s no way to know for certain whether this type of issue is software- or hardware-related. The most that you can do is to see what you did previously that may have led to this problem. If you are positive that the only change to the system was the installation of an Android update, then you’ve probably installed a poorly coded firmware version. Since a factory reset did not fix your issue, the only solution left for you, other than a phone replacement, is by reverting the firmware to its previous version — Android 6. Be sure to use a good guide should you wish to flash an older Android version on your phone.

Problem 2: Galaxy S7 keeps restarting after using it under water

Hello. Today I went to a water park for my sister’s birthday, so i used my Galaxy S7 in the water, also under it. It worked perfectly all day. about an hour later I left my phone on the car and when we were leaving, it worked normally but it started to get very hot so i turned it off. Now it keeps turning off and on. It only shows the Samsung Galaxy S7 logo for a few seconds then shut back off and it keep doing the same thing without stopping. I can’t get it completely off or on. It also keeps getting hot even like that. — Alex

Solution: Hi Alex. First of all, a case like this is almost always hopeless because you are basically unable to do any software troubleshooting on the device. If the only different thing you did before was to use it in water, there’s a chance that its internal components may be compromised. Remember, an S7 is water resistant only, not fully water proofed. Any unnecessary water pressure (present when moving the phone under water) can force moisture inside.

Secondly, you want to try restarting the phone to other modes to see if you can stabilize it to an alternate mode. If you can’t, we don’t think there’s any other troubleshooting that you can do on your end. You must send it in for repair or replacement.

Below are the steps on how to boot your phone to other modes:

Boot in Recovery mode:

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

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to do it.

Boot in safe mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and hold the Power button.
  3. Once the Samsung Galaxy logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Problem 3: Galaxy S7 unable to make voice calls and keeps getting error message saying SMS can’t be sent

I have a factory unlocked Samsung Galaxy S7 which I have owned for the past several months. Starting approximately two days ago, I began to be unable to make calls to certain people (the other people had both Android and Apple phones). This issue then escalated to where when I try to send a text message I get a sending symbol until eventually it says the message cannot be sent. However, my messages still appear to go through because people can reply to me and calls can be made to me. The issue is very annoying because I am constantly getting message not sent messages and it is also difficult to know when my message has genuinely not sent. I have tried a hard reset which wiped me to factory reset and I have also cleared my system cache. I have contacted my provider as well and they say everything on there end appears to be fine. Please help. — Devin

Solution: Hi Devin. Was there anything that you did differently before experiencing these problems like install an update or app? If you did, try to reverse it and see how it goes.

You can also try another factory reset and observe the phone. We know you already factory reset your device prior to contacting us but most people do it without observing their device afterwards. If you haven’t done that, here’s what you need to do exactly:

  1. Do a factory reset.
  2. Observe the phone for at least 24 hours. Test how sending text and voice calling works.
  3. Make sure not to install anything (app or update) during this time. The aim is to see if there’s any difference when the phone is running a clean software.

If SMS and voice calling works normally during observation period, that’s an indication that one of your installed apps is to blame.

On the other hand, if the problems remain during observation period, it can mean that there’s a glitch with the operating system or hardware. In either case, you want to have the phone replaced.

Problem 4: Galaxy S7 screen shows tan or sandy color

The screen has darkened. If I were to go on Google for example, the internet won’t be white and instead it is a tan or sandy color. It was working fine in the morning then I put my phone in my back and when I took it out, the screen is now a tan color. I don’t think water, dust sand, dirt ect caused this because my bag is clean and water has got on my phone before and the screen was fine but now it’s not and I don’t know what caused this or how to fix it. — Pegbuchunam15

Solution: Hi Pegbuchunam15. Pull up your phone’s service menu first by doing the following steps:

  1. Open Phone (dialer) app.
  2. Dial “*#0*#” (without quotes).
  3. Test how your device’s screen change colors by tapping Red, Green, Blue, and Black boxes.

If the screen remains the same, that is, it continues to show tan or sandy colors, you have a broken screen at hand. You should have the phone repaired or replaced.

On the other hand, if screen’s color change according to the box that you tap, that can mean that there may be an operating system problem. You should try a factory reset to fix it. Here’s how:

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  2. Turn off your Samsung Galaxy S7.
  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 data / factory reset.’
  7. Once highlighted, you may press the Power key to select it.
  8. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  9. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  10. The phone will now reboot longer than usual.

Problem 5: Galaxy S7 edge stuck in boot loop

I have a Samsung Galaxy S7 edge which hasn’t been working for a week. It’s stuck in bootloop it won’t get past the samsung galaxy s7 edge screen at the start. I’ve tried putting it into safe mode to clear cache and reset the phone which worked previously when I had a similar issue, but this time when I press the buttons to go into safe mode it just comes up with a screen saying no command with a dead android guy. I’m starting to think the only other thing I can do is root my phone but I wouldn’t even know how to go about that. I hope you can help, Thanks in advance. — Danielle

Solution: Hi Danielle. If doing a factory reset via Recovery mode (check steps above) did not help, the only other option for you at this time may be flashing the bootloader and/or firmware. Below are the sample steps on how to flash a bootloader. The exact steps for your device may be slightly different so make sure to do some research how to do this. Flashing instructions vary by phone model. The steps below are for demonstration purposes only. If you don’t think you can do it, let someone with more advanced Android knowledge do it for you.

  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.

IMPORTANT: Flashing the bootloader or firmware can potentially brick your phone for good if not done properly. Be sure that you know what you’re doing before committing to it. You don’t need to understand how the entire process works but you want to be aware of the risks you’re taking.

Remember, flashing is not a guaranteed solution and there are lot of cases that it won’t help. If the problem stays, have the phone repaired or replaced.

Problem 6: Galaxy S7 keeps rebooting on its own after an update

My Galaxy S7 on EE network in Britain recently updated by the network. It worked normally for a while. I switched it off last week in the night and when switched on in the morning it just now keeps switching off and on. It stays on for variable times between 2 to 30 seconds max. I did the delete cache but still the same. I tried safe mode reboot but still the same. I have pictures and files on the phone I want to access but smart switch does not have time to connect to my new S8 I had to buy. The EE people in the shop say they can only wipe it and repair/replace since it is within warranty. Please help with any ideas to recover? — Gerzz

Solution: Hi Gerzz. You need a stable system in order to move files back and forth so we’re afraid you don’t have much choice in this matter. If you want to fix the issue though, you can try the suggestion we have for Danielle above. Flashing will delete the operating system though so you’ll still lose your data.

Problem 7: How to recover files from corrupted SD card in Galaxy S7

Hello. I have a Samsung Galaxy S7 and I save most of my pictures to a microSD card. One day, I noticed my camera album was missing, but didn’t think much of it. A little while later, I noticed that albums from a couple of large trips I had taken were gone. There are still some albums remaining and plugging the SD card into a PC gives no files other than what shows up when I open the file manager on the phone. Turning the phone on in Safe mode shows nothing additional either. Do you have any suggestions? Any data recovery program that you recommend (or will data recovery not do anything since there is still information on the SD card)? Any help you can offer is so greatly appreciated!! Thank you! — Kassie

Solution: Hi Kassie. Data recovery is a tricky business so there’s no telling what you might be able to get. If you think those missing files are worth a few hundred dollars to recover, we suggest that you visit Google to search for third party companies that offer data recovery service. Make sure to ask the terms of their service before paying so you’ll know what to expect. Some companies won’t charge you if they can’t recover anything but others may.

Problem 8: Galaxy S7 S Beam and NFC

My Samsung Galaxy S7 had a black screen issue after 6 weeks so it was returned and replaced. I received it in the mail and did the set up and restored it. After that was completed, I checked all my pics to clear them and make room to do the update. I had about 20 videos that was from my sister’s phone. I posted them to her on FB to get more room so I could do the system update, as space was needed. Everything was fine, except for the update loop, but that’s ok. The next day I went to look at the pics, since I had lost some from old phone and they were there. There was also about 100 of my sister’s pics now. We have never used the S Beam or NFC. It is driving us crazy how I got all them. Different phones, different providers, and they have never shown up for a restore before. All the pics and videos were from 2013, that’s it, no recent ones. Do you gave and clue what is going on? — Karen

Solution: Hi Karen. We don’t think we understand your point here. Can you please get back to us with clearer questions? We’ll update this post accordingly.

Problem 9: Galaxy S7 overheating and won’t turn on after it got water damaged

So I went swimming and since my phone is the Samsung Galaxy S7 I knew it was water proof. So I tested it in the pool but only put the phone under water for about 5 seconds tops. I dried it off after that and then set it aside in the shade and when I checked on it later it was already off. So I turned it back on but when I opened it it started glitching and switching between the home screen and the multiple tab screen (where it shows all the apps that are open). it kept doing that for a while and it kept shutting down because the battery was overheating until the battery died. Now when I charge it the battery sign shows up with a yellow triangle with an exclamation point in the middle. I looked it up and I know there is water damage because it said that under the battery there is a white square and if the square has red on it there is water damage. Now I just need help on how to fix my phone so I don’t have to pay for a new one or how much it will cost to fix it. –Arielrz2015

Solution: Hi Arielrz2015. First of all, your phone is not a water proof device. It’s only covered with water resistance protection, technically an IP68 certification, which means it’s not immune to water damage at all. Giving you the difference between water resistant and water proof devices is beyond the scope of this article so hit Google and do your research.

Secondly, the only effective solution (if you can call it a solution at all in this case) for a water damaged phone is repair. We can’t even be sure if your phone can still be fixed at this time. In an ideal situation, you’re supposed to turn off the phone, remove the battery, and dry the phone thoroughly to ensure that no moisture is left inside the device. Not doing them in the first place puts your phone in a uncertain situation. Depending on the affected component, the phone may or may not have permanent damage at this time so even a good technician may not be able to fix it. Anyhow, we strongly suggest that you have the hardware checked so you’ll be advised whether it can still be saved or not.

Finally, to prevent this issue from happening in the future, never ever intentionally expose your electronics to water, even if they have water resistance protection. You already know what can happen.

Galaxy Note 5 won’t work with in-vehicle Bluetooth system, showing screen discoloration, other issues

Hello Android community! Welcome to our most recent #GalaxyNote5 post for the day. In this article, we’re bringing you 8 more Note 5 issues we’ve collected for the past few days. We hope the solutions in this material will be useful not only for guys mentioned here, but also for the rest of Android users.

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 Note 5 showing screen discoloration

Hi. So i am having issues with my Samsung Galaxy Note 5. I haven’t dropped it or anything. I don’t go to any malicious sites that could cause a virus. I have noticed a green line on the left side of my screen all day long. I was really annoyed for a little bit, tried restarting it nothing helped. I was looking at Instagram, then the right side went dark and the left side is blinking. Not a solid color, it goes from dark to light with varying colors in between. Do you have any idea as to what is going on?        — Ruthy85.aw

Solution: Hi Ruthy85.aw. Any abnormal discoloration of the screen usually signals a malfunctioning hardware. To see if that’s the case, try to boot the phone to either Recovery or Download mode to see if something will change. Any of these modes won’t run Android operating system and apps so if the problem is hardware-related, the screen should show the same annoying discoloration. If that’s the case, you should have the phone repaired or replaced.

Below are the steps on how to boot to either Recovery or Download mode.

Boot in Recovery mode:

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

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to do it.

If the problem won’t occur while the phone is in Recovery or Download mode, the issue must be caused by either Android operating system or app glitch. Do a factory reset and observe how the phone works before installing any app. Here are the steps on how to factory reset your Note 5:

  1. From the Home screen, tap the Apps icon.
  2. Find and tap the Settings icon.
  3. Under the ‘Personal’ section, find and tap Backup and reset.
  4. Tap Factory data reset.
  5. Touch Reset device to proceed with the reset.
  6. Depending on the security lock you used, enter the PIN or password.
  7. Tap Continue.
  8. Touch Delete all to confirm your action.

Problem 2: Galaxy Note 5 apps keep stopping, shutting down on its own

Good day! I do have a specific problem with my phone and i hope you can help me.

 

  • App. My apps in my Note 5 often stopped, even if i didn’t use it. For example, I’m just scrolling in my Gallery and eventually something pop up and it said “Twitter has stopped.” (This kind of context and even in my Samsung Keypad and other apps it also happens). The other apps also stopped just what i described above mention. So what i do is restart it so everything will refresh, but after few minutes it will happen again.
  • Automatically Restarting. This happen often also i just don’t know how to solve this restarting problem and when its restarted my network doesn’t work so what i do is i personally restart it so when it restart again my networks will reread and start working again. I hope you could help me. Please.. thank you so much. — Kristoffer

 

Solution: Hi Kristoffer. Try wiping the cache partition first and see what happens afterwards. This troubleshooting step is necessary to force the phone to refresh the system cache. Sometimes, the system cache gets corrupted after installing an app or update, resulting to all sorts of problems. To fix the issue, you want to clear the cache partition where the system cache is housed. Below are the steps on how to wipe the cache partition:

  1. Turn off your Samsung Galaxy Note 5 completely.
  2. Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  3. Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  4. Once the Android logo shows, release both the Volume Up and Home buttons.
  5. The notice ‘Installing system update’ will show on the screen for 30 to 60 seconds before the Android system recovery screen is shown with its options.
  6. Use the Volume Down key to highlight the option ‘wipe cache partition’ and press the Power key to select it.
  7. When the process is complete, use the Volume Down key to highlight the option ‘Reboot system now’ and hit the Power key to restart the phone.
  8. The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

If nothing will change after wiping the cache partition, you should return all software settings to their defaults. This is done by performing a master reset. Here’s how:

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  2. Turn off your Samsung Galaxy Note 5 completely.
  3. Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  4. Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  5. Once the Android logo shows, release both the Volume Up and Home buttons.
  6. The notice ‘Installing system update’ will show on the screen for 30 to 60 seconds before the Android system recovery screen is shown with its options.
  7. Use the Volume Down key to highlight the option ‘Yes — delete all user data’ and press the Power key to select it.
  8. When the process is complete, use the Volume Down key to highlight the option ‘Reboot system now’ and hit the Power key to restart the phone.
  9. The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

Problem 3: Galaxy Note 5 screen stays black

I actually have bought the too much expensive Samsung smartphone Note 5 but such kind of accident with smartphone …  its LCD display went on dimming and dimming. it colour display black slowly and slowly eventually went black after 1 week time period .. but at that time the all thing was working means its sound, touch, call, sound, led light … and also these all thing also work today when i see the smartphone note 5 … but still its showing nothing any display on it … But the issue is related to this … kindly guide me or contact mr on no. 03********4 or my Gmail account please as soon as possible. — Dilawar

Solution: Hi Dilawar. We don’t think we understand your concern correctly but if you’re having an issue with your screen not turning on, the only other option for you is to have the hardware checked by a technician. Software troubleshooting can only be done with a working screen. If your phone powers on but the screen stays black or unresponsive, you won’t be able to do perform anything. A black screen such as this is usually indicative of a damaged screen. Consider sending it in for repair or replacement.

To see if the black screen issue is caused by a software or app bug, try booting the phone to alternate modes. Here’s how:

Boot in Recovery mode:

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

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to do it.

Boot in safe mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Problem 4: Galaxy Note 5 not working with Bluetooth headset and Bluetooth speaker

Just installed the new nougat software and when I have my Plantronics Bluetooth paired with my phone and I get into my car or truck that has Bluetooth, my vehicle Bluetooth will pair while my Plantronics is already paired. So when I get a phone call I have 2 Bluetooth trying to answer the call at the same time. Sometimes my vehicle Bluetooth would answer the call, then my Plantronics Bluetooth would interfere and try to connect.

Before the update if my vehicle Bluetooth saw that my phone was paired with my Plantronics Bluetooth it would not try to pair with my phone until I unpaired manually from my Plantronics Bluetooth. I’m trying to figure out why I have this problem now and what can I do to fix this problem. I did a restart and that didn’t help and of course with the newer Samsung you can’t remove the battery for a restart. — Christian

Solution: Hi Christian. An issue like this happens often due to incompatibility. If the only different thing you did was to update your phone, that means that the two other Bluetooth devices may have become incompatible with it. If you can’t fix the problem by un-pairing all devices, deleting all Bluetooth profiles, and re-pairing them, you must try to do the following:

  1. Wipe the cache partition of your Note 5.
  2. Factory reset the Note 5.
  3. Factory reset other Bluetooth devices.
  4. Install updates for your Note 5.

If the steps above won’t work, try to update your two other Bluetooth devices as they have obviously become outdated or incompatible with the new Bluetooth system on your Note 5.

Problem 5: Galaxy Note 5 won’t work with in-vehicle Bluetooth system

Hello. So, I have a Samsung Note 5 and since this new update I installed I can’t connect to my car Bluetooth, which is a Clarion NX602 nav bluetooth system. I should say it connects like it says on my phone connect but no one can hear me. plus the big deal breaker: there’s no audio sound option so I can’t even listen to music I downloaded on my phone to the car.

I used to be fine without this new update. Everything worked but it seems this new update screwed with my Bluetooth. Any idea what I can do? i reseted the cache etc and tried on safe mode still nothing. It just shows call audio and that’s it. FYI: when I go connect it to a portable Bluetooth speaker, I have it works just fine. The audio and stuff volume is all there just not for my car. — Bruno

Solution: Hi Bruno. Your issue is similar to Christian’s above so kindly refer to our suggestion for him.

Car Bluetooth systems do not receive regular updates as often as smartphones do so older devices tend to become incompatible as time goes by. This is often the problem encountered by car owners who rely on their in-vehicle Bluetooth system for communication or entertainment. To fix your issue, contact your auto maker or the manufacturer of your car Bluetooth system to see if there’s any way to make their system compatible with the Bluetooth in your phone.

Problem 6: Galaxy Note 5 camera not working when using Instagram

I have a Galaxy Note 5 by Verizon that I just got from a friend and he reset it for me. I installed Instagram and my usual apps afterwards. I tried opening the camera on Instagram and it told me about the screen overlay. I turned that off and that went away. But then Instagram had a pop up that said “take photos and videos using the Instagram app.” So I clicked turn on: it then takes me to the app info for Instagram where my permissions are turned on for the camera and storage BUT I still can’t use my camera on Instagram. I go back to the main camera again and it takes me right back to the app info. Please help because I’ve tried everything and am at a loss. — Caitlin

Solution: Hi Caitlin. Try to delete the app’s cache and data and see what happens. This troubleshooting step is often the first thing a user must do if faced with a problem with a particular app or apps. Below are the steps on how to do it:

  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 Data and Clear Cache buttons for the application.

Should clearing Instagram’s data won’t work, do a full factory reset. Refer to the steps above.

Problem 7: Galaxy Note 5 screen stays black, not working

Good day The Droid Guy. My Samsung phone has been through contact with water (not so deep though) but i immediately brought it out on water without a second (the screen was still on). I also immediately dried it out a bit and settled it in a container with rice. After a couple of hours, i turned it back on and it was working just fine as it was before.

Now after weeks, it wasn’t charged for 2 days straight (i was having fever) I had it charged it back again and then it has been having white horizontal lines on screen but still can still be swiped. The next day when i was still using it, the display would suddenly disappear but after pushing some button it shows again.. until one time the display didn’t show once more unless if you let the phone restarts. The Samsung logo would appear and nothing shows up again and today the phone now would only vibrate if the power button is pressed. Nothing shows in the screen anymore.

I also already had personal contact with some technicians in town. They’re saying that the LCD is broken and must be replaced at a very high price. I’m humbly asking for your opinion and suggestions on what must be done. Please give and advise some alternative ways that I can do to get my phone back to life again. Other than negotiating to a risky price on replacing its LCD. Thanks and MORE POWER. — Zhenaseguido

Solution: Hi Zhenaseguido. If the hardware has already been assessed by a technician and it’s been established that the screen is damaged, we’re afraid there’s not much option left for you. There’s no software hack that you can do to fix a bad hardware. In your particular case, there’s no settings to change or code to modify in order to make the screen to work again. You must have the screen assembly repaired or replaced if you want to use your phone again.

Problem 8: Galaxy Note 5 screen turns unstable when using clock apps

I’ve read the pages about the yellow/green flashing screen. I also have this problem but it seems to be associated with the Night Clock apps that I have tried recently. These apps mean that the display is on for several hours (so I can see the time while half asleep at night). The phone is also left charging overnight. The display starts flashing unstable by about 2am so I have to close the clock app. In the morning the display is very unstable and it can take ages before I can use the phone. I sometimes re-boot the phone, but this seems to make no difference. During the course of the morning it settles down and is stable by lunch time. Does the display not like to be alive but unused for a long time (several hours)?

The same problem occurs with a number of clock Apps (e.g. My Alarm Clock, Nice Night Clock) not just one specific one. I contacted the Help Desk at My Alarm Clock, and they investigated for a while but could not help in the end. Do you know of a clock app which does not have this problem? Regards. — Bob

Solution: Hi Bob. If your phone displays the same screen behavior regardless of the app clock you’re using, the problem must lie on the device itself. There must be an unknown software or hardware glitch that causes this isolated issue. We have our own Galaxy Note 5 and we tried to install the apps you mention here. So far, we haven’t observed any screen problem, especially the one you’re experiencing.

If a factory reset won’t fix your issue, consider getting a new phone.

Galaxy S7 SD card not detected, keeps getting pop ups, other issues

Hi guys! Here’s our last #GalaxyS7 post for the week. We hope you’ll enjoy reading the issues and their respective solutions.

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 S7 purchased in the US not working in India

Hi All. I am having two problems. i hope if you guys can help me out.

1) I bought one Samsung Galaxy S7 edge phone and I have been told that this phone is factory unlocked worldwide. I bought it in the US and mailed it to India. When my brother inserted a SIM on it, no signal show up. Then I told him to reset, changes settings in Network but no luck. Then finally he reset it to factory unlock.

2) After factory reset still have same issue. No signal coming on phone but now when I restart my phone I am seeing Android logo on screen where as I should see SAMSUNG logo while starting up phone. Does this means my phone is not genuine as I am not seeing SAMSUNG logo or is there anything I have to do to change it. — Mukesh

Solution: Hi Mukesh. There are a couple of things to consider if you want to go to the bottom of the issue.

CDMA vs GSM. This is the first thing that you must consider when planning on using a phone to another network. CDMA (Code Division Multiple Access) and GSM (Global System for Mobiles) are two of the most common wireless technology that most carriers around the world are using. CDMA is not compatible with GSM and vice versa. Needless to say, the difference between them is usually the main reason why phones won’t work in another network. For example, in the US, Verizon phones usually won’t work at all, or may have some limitations when used in a GSM network like AT&T. Verizon uses CDMA while AT&T GSM. Because a CDMA phone is built differently than a GSM phone, even though they’re of the same model, you’ll still encounter incompatibility issues. The same can be true in your brother’s case. If the phone you gave him was CDMA and he’s on a GSM network, there’s no way that phone will work.

We know you were told the phone was unlocked but most of the time, it doesn’t work at all. Unlocking a phone only changes some software settings, particularly on the network function, but the hardware remains the same. A network unlocked CDMA phone may or may not work properly when used in a GSM network.

CDMA phones are more restricted than GSM phones. GSM phones store subscriber information in SIM cards so as long as it’s properly network unlocked, you can easily use another SIM card from another network and it should work. CDMA phones don’t work like that because subscriber’s information is coded deep within the software. CDMA phones may sport a SIM card slot but that doesn’t work like a GSM phone does. The SIM card is there to allow a CDMA phone to use 4G LTE, which is just a modified GSM technology. CDMA phones still need to dig deep into each software everytime a user want to make a call or send SMS. Needless to say, CDMA phones are usually locked to its original carrier.

Giving you more details about this topic is beyond the scope of this article so we recommend that you do your own research about it.

We know nothing about your brother’s phone but if you want to know if it’s a CDMA or GSM phone, simply do a quick Google search for its model number.

Different frequencies. Samsung build phones with a specific carrier in mind so it’s not uncommon to find a Galaxy phone model having many variations. For example, hardware specifications of Verizon is different from hardware specifications of AT&T phones. This means that even if both phones look the same outside, their hardware differ significantly inside. One of the significant differences can be the operating frequencies. Each carrier works in a certain radio frequency to avoid interference so each of their phones must be provided with compatible networking chip so they can operate properly. If the frequency of the phone is different from the frequency of your brother’s carrier, the phone can’t simply find the signal. Unfortunately, there’s nothing much that you can do about that since frequency capability is determined by the hardware installed. You cannot remove the networking chip from a phone and replace it with a different one. Again, we recommend that you do some research about this topic if you want to know the cause of the problem. Have your brother contact his carrier to ask for help regarding this matter.

Problem 2: Galaxy S7 not receiving SMS from iPhones and My Sprint app not working

Hi. I was recently at a Doctor’s appointment and logged onto their Wi-Fi. Since I returned home I cannot receive any texts from anyone with an iPhone. Also “My Sprint” is not working at all and my Google voice is not allowing texts to come through my normal messaging app.

All of my updates are complete and I tried to reboot my phone and also went into wifi and clicked on the Doctor’s office wifi and said to “forget” it but still nothing.

Please advise as I am literally having the day from hell between my phone an ld my druer being broken. Thank you. — Tlynalu

Solution: Hi Tlynalu. We can’t see any reason why SMS would stop working after using a different wifi network. Something must have changed in your phone’s networking settings to cause the problem. We’re not familiar with your phone, nor did you provide more information to help us identify the cause. We recommend that you contact your carrier for assistance.

Problem 3: Galaxy S7 stuck in Sprint logo screen after deleting files

I have the Samsung S7. Last night, I did a clean up of cache and old pictures. This evening i used my phone till it died. I charged it and turned it on upon 100%, however the screen locks at the Sprint flash logo screen. It stays on the screen and makes the battery hot. What is going on with my phone? Please help, i have tons of valuable pictures that i would hate to lose. — Rookie704

Solution: Hi Rookie704. We don’t think you only deleted cache and pictures. If you are 100% positive that all you did differently before noticing the issue was to delete some stuff, you must have deleted some critical files or folders that caused this problem. If your phone won’t restart normally now, you don’t have a lot of options.

Try to boot the phone to Recovery mode first and see if you can fix the problem by wiping the cache partition. If cache partition wipe won’t solve the issue, you should try a factory reset. That will delete your data of course but as we’ve said, you really have not much choice.

Here are the steps on how to start the phone to Recovery mode:

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

Problem 4: Galaxy S7 edge screen showing red and green dots after an update

On 14th June i downloaded the latest android version in my S7 edge and leave it to install over night. And when i wake up i start watching some videos, then i noticed there are some green and red dots on the screen. So i locked the device and reopened it. the dots are gone but after half a minutes the screen turns green and start flashing. At first i thought somehow i break the display or might some water in gone inside it though the mobile is water proof. i tried to restart it but i can’t because i can’t see any thing. But after some while it turn backs to normal but the dots and green screen still flashes from time to time jut for a blink. — Hamza

Solution: Hi Hamza. Try to wipe the cache partition first. If nothing changes, do a factory reset. Below are the steps on how to do each of them:

How to wipe S7 edge cache partition

Turn off your Samsung Galaxy S7.

Press and then hold the Home and Volume UP keys, then press and hold the Power key.

When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.

When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.

Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’

Once highlighted, you may press the Power key to select it.

Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.

Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.

The phone will now reboot longer than usual.

How to factory reset an S7 edge

  1. Turn off your Samsung Galaxy S7.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

Problem 5: Galaxy S7 screen is black after water damage

My S7 edge which I bought a month ago fell in water. The screen blacked out and only blue light was showing. However I can feel and hear sounds coming from the device even though it’s black. I tried to reboot through various steps. at last I went to the place where I bought the phone. They opened it and found out that water has sipped in from SIM card sections and told me I have to change the screen but they don’t guarantee it will work. I’m confused, if i buy a new LCD screen will it work? Please assist. — Shanit

Solution: Hi Shanit. When it comes to water damage, no repair is guaranteed. There’s no way to know in advance if the current issue can be fixed by replacing a single component — the screen assembly. Water can damage other components in the motherboard and screen replacement may fix the black screen issue but the phone may work erratically in the near future, especially if there’s corrosion in the motherboard. The best thing that you can do is to let the device be checked by a good technician so you can get an honest assessment. If they’ll say that repair may not guarantee that the phone will work afterwards, you are better off getting a new phone. We know that option can be difficult but again, there’s no telling what components are damaged right now.

Problem 6: Galaxy S7 messaging app issue

I am using the message app that came with my Samsung Galaxy S7. I am having an issue with the message display screen that shows different people that I have texted. One time I can turn on my phone and the last message displayed will be what I sent to someone, but I have to select the person/conversation and open it to see their response. The next time it might show their response to a message two days ago, but not the message that I sent this morning without selecting the conversation and opening it. I would like it to always show the last communication in the response – whether it is me or the person that I am talking to. Any suggestions? I have rebooted it, but I can’t take the back off of this phone. — Tonnette

Solution: Hi Tonnette. We don’t think we understand what you’re trying to accomplish here but if you’re having trouble with one app, you can always try wiping its cache first, then its data later. Keep in mind though that clearing your messaging app’s data will erase your SMS conversations. If you don’t want to lose your SMS, try backing them up first using Samsung Smart Switch app.

Below are the steps on how to clear an app’s cache and data

  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.

Problem 7: Galaxy S7 keeps saying SMS sending failed

My wife and I have S7s that just received the Android 7 update (hers a few days ago and mine a few hours ago). Since her update (and now mine) we both have the same experience with SMS/MMS messages. We get an error that the text failed, BUT it actually goes through! She did a factory reset last night and it did not correct the problem. We installed a new messaging app on her phone and it did not help. I reset the settings on my phone and no help. Any ideas? — Bigelot

Solution: Hi Bigelot. It can be an operating system-related issue. This means that the firmware update you installed (which was provided by or modified by your carrier) is poorly coded. Make sure to report the trouble to your carrier so they can look into it.

Problem 8: Galaxy S7 no notifications for MMS

My phone randomly stopped notifying me that I received group text messages. I went to investigate the problem and when I go to messaging settings>more settings>multimedia messages> turn on auto retrieve and roaming auto retrieve it then notifies me when I get a group text. BUT it notifies me as an individual message and I have to download each person’s response individually. It then adds the message to the group message. It’s extremely annoying and hope you can help me fix it. Thanks! — Courtney

Solution: Hi Courtney. Try wiping the messaging app’s cache and data first and see how it works. If nothing will change, do a factory reset. Refer to the steps above on how to do each of them.

Problem 9: Galaxy S7 SD card not detected, keeps getting pop ups

Hello. Yesterday my 32GB SD card disappeared and will not show in my file as being inserted even though it’s still in my phone. Today I took it out and put it in my Samsung tablet and it was not recognized as being inserted in there either. The only thing i have not did yet was put it in a card reader and insert it in a laptop. That’s my next move. My question is what did this? All i did was restart my phone because it said that i have not done so in a few days. I have done this a lot and I’m not 100% sure if the SD card was done before or did that but I’m pretty sure that it was. Im sick i have lost a lot of great music and no it was not backed up. At one point it was but someone stole my flash drive It was on. Is there any way to retrieve what’s on this SD card?

Also for about 2 months I keep getting a pop-up or something like that on my S7. It’s annoying. Is there a way I can get rid of it? When I went to the T-Mobile store they told me no. Hope to hear from you soon thanks. — Tamar

Solution: Hi Tamar. As we’ve always stressed in a lot of our articles, digital storage devices like SD cards are unreliable. They can die anytime without leaving a trace on what may have caused them to stop working all of a sudden. To discuss the entire gamut of possible causes on why an SD card dies is beyond the scope of this article but you can always Google it if you have the time. Knowing what caused your particular SD card to die is impossible so it’s best if you can leave it that way.

We want to give you some useful tips though on how to minimize this issue from happening again. Here are a couple of them:

  1. Avoid interrupting the system or device (by turning it off) when it’s trying to read from or save to the SD card. Some apps can be saved in an SD card and if you turn off your phone while an app is loading, it can corrupt the SD card. The same is true when the phone is trying to move files to and from the card.
  2. Unmount the SD card properly before physically removing it. You can do that by going under Settings>Device maintenance>Storage.

You can also visit our previously published post for more tips on this topic.

For the pop up issue, the answer really depends on what type of popups you’re getting. If they are ads or something that promotes a product or another app, your phone is probably infected with a virus so you would want to factory reset it first. After that, you want to make sure that you only install apps from trusted sources. Viruses in Android mostly come from bad apps so you only have yourself to blame if you don’t filter apps you install.

If you’re getting system notifications, you may be able to fix the problem by tweaking some of your settings. Next time you contact any support team, always provide as many details as possible. In this case, it would have helped us a lot if you included more details about the pop up, or provided more descriptions about it. You can’t expect us to help you if you give us anemic description of your problem.

Galaxy J7 only stays on when connected to charger, battery not working, other issues

Hello J7 users! Welcome to our latest J7 post for this week. We discuss 9 issues today and hopefully this material will be useful for you.

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 clock not working

Hi. Sometimes the clock just stops on my Samsung J710. For instance, it hits 2:30 AM and it doesn’t change even a few hours later so it affects my alarm clock too (it doesn’t go off). Sometimes the clock on the upper right side even stays wrong after the main clock display has righted itself. The upper right clock only repairs itself if I go to the setting – clock and date. Although it seems like a small problem, I can not rely on the basic phone function. When it happens that clock frozen, the alarm will not ring, but if I go to the Setting – Date and clock – there is a right time. As if the clock is not connected with the screen at some point. — Natasha

Solution: Hi Natasha. The first troubleshooting step that you want to do is to check if another app may be behind the problem. You can do that by booting to safe mode and observing it for at least 24 hours. While safe mode is enabled, all third party apps, that is, apps you install after you set the phone up the first time, will not run. If your phone’s clock will work normally while safe mode is on, that’s a confirmation of our suspicion. To restart your phone to safe mode, kindly do the following:

  1. Turn the device off.
  2. Press and hold the Power key past the screen with the device name.
  3. When ‘SAMSUNG’ appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see ‘Safe Mode’.

If the problem continues and booting to safe mode won’t change anything, wipe the phone clean via factory reset. There may be an unknown software bug causing this erratic behavior. To factory reset your J7, follow these steps:

  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.

Problem 2: Galaxy J7 mobile data keeps disconnecting when using browser

Hello. My mobile data/3G isn’t working. I have a package with my provider but everytime I turn my mobile data on, I go to browser on my J7, I try to load up or go to a website or search something I just get the message coming up saying mobile data is switched off or please connect to wifi. but I know it’s the mobile carrier’s fault as everytime I get my monthly package for internet automatically renewed I get a confirmation message sent to me. but everytime I try to use mobile data it just says mobile data is switched off on the browser screen I’m sorry but I don’t know what my Android version if you could tell me how to check it I will happily tell you. — Antonio

Solution: Hi Antonio. We don’t know what subscription scheme you have with your carrier but you really should fix this issue with them. There’s no device troubleshooting that you can do on your end if your carrier keeps disconnecting your mobile data service for some reason. If your phone can’t connect to the internet when using both the browser or other apps that need internet to work, you must ensure that your mobile data subscription is in good standing all the time. If it’s already in good standing, which means that you pay your dues on time and you’re not going over your data consumption limit when the problem occurs, work with your carrier to figure out what causes their service to disconnect. If they can’t identify the problem on their end and you need mobile data badly, we say it’s probably high time to switch to a better service.

Problem 3: Galaxy J7 “Unfortunately, contacts has stopped” error

I have done every step of suggested troubleshooting for “unfortunately, contacts has stopped”. The error message pops up when the “green phone” icon is tapped. The actual contact list is available just not the key pad. And it’s not because I hit the “hide” key pad icon. I’ve had two J7s in the last 4 days. On the first J7 after doing every troubleshooting step except for factory reset, T-Mobile replaced the phone. On the replacement phone, I installed 3rd party apps again. Within 48 hours (same time frame as first phone) same error message. Before going back to the store I uninstalled all third party apps, tried all troubleshooting steps except factory reset. I want the store to do that step. Factory reset done. Phone keypad showing. I installed third party apps again. Within 48 hours “unfortunately, contacts has stopped” error message again. As if I wasn’t frustrated already. 2 phones, same time frame, same third party apps, same error message. I really do not want to go back to the T-Mobile store. Some of the sales reps already leave when they see me enter the building. Are there any 3rd party apps that could/would be triggering the error message? Or something? Thanks. — Terri

Solution: Hi Terri. “Factory reset done. Phone keypad showing. I installed third party apps again. Within 48 hours “unfortunately, contacts has stopped” error message again.” That alone should tell you that this problem is caused by a third party app. This means that of your third party apps is buggy and creating a conflict with the Phone app, or the operating system. That’s more than a clear indication it’s not a device issue but something that you keep on re-installing for a few times now. Even if you’ll get a thousand J7s, the same problem will occur. It’s common sense; uninstall the problematic app to fix the problem!

You won’t be able to uninstall the app if you can’t identify it so your main task is to narrow down the possible culprits. Uninstall apps one by one and observe how Phone app works after each uninstall. This is the only way to pinpoint the buggy app.  Keep in mind that not all apps are built equally. Some may work flawlessly while others may result to problems. If you tend to install apps without checking the reputation of their developers, you will most likely encounter problems similar to what you’re experiencing right now. Be sure to install apps from official or good developers only.

Problem 3: Galaxy J7 dropped in toilet, now screen won’t turn on

I dropped my Galaxy J7 in the toilet. I put it in rice. It now turns on but the screen won’t do anything. All my stuff is there. But I can’t open anything up. Move my screen back and forth nothing. My volume button works, charging works. Just my screen itself won’t do anything. I do have in the right hand corner a black part on the screen, just a small area. And when my screen shuts off I have to take the battery back out to get it to come on. And then I will have a thing come up and say turn your device off and insert the service provider hiccups that came with the device…anyone know what I should do? — Bobbijojohnson69420

Solution: Hi Bobbijojohnson69420. Have the phone checked by a trained technician. This is the only way for you to know if the phone can still be saved. If you’re lucky, water damage may lie in the screen assembly only so replacing this part should bring everything back to normal. If your phone got fully submerged in water though, it’s best if you don’t bring your hopes up too much. Even if a technician can replace the screen successfully, corrosion in the motherboard can still develop after some time, resulting to multiple component failure. If that happens, it will never be practical to have the phone repaired. Sometimes, water damaged phones can work for a few days after repair, allowing users to extract important data before finally succumbing to permanent failure. If you think your data are worth a couple hundred dollars, you can have the phone repaired first to assess the damage and probably go with screen replacement so you can get to your files. After that, don’t expect much. Consider getting a new phone.

Problem 4: Galaxy J7 sends SMS very slowly

Pictures send instantly! Sometimes texts send instantly, but sometimes texts take several minutes to send UNLESS I attach a picture to the text. If I do that, the texts will go instantly with the picture. Sometimes, by itself, a text won’t send at all.

I’ve done and tried several things by turning something off to see if that helps and when it doesn’t, i turn it back on again. It acts like signal strength issues, but the phone always shows a strong signal and a strong wifi signal at home. If it is indicating the correct signal strength, then that is not the problem. The problem started shortly after i installed the Amazon music app. I have background data restricted for apps. I took that restriction off but it didn’t help. Any help you could offer would be appreciated. — Lsr1713

Solution: Hi Lsr1713. We haven’t heard of Amazon app causing a problem like this on any phones before but you want to consider all possible factors at this time. If you’re positive that the issue occurred right after installing the Amazon app, you should uninstall it and observe the phone for at least a day. This will allow you to notice any difference with and without this app installed.

If removing the Amazon app won’t help, your next move is to clear the messaging app’s data. This will force the phone to revert all settings of your messaging app to their defaults. Here’s how it’s done:

  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, look for the messaging app you’re using and tap it.
  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. Tap Clear Data option.

Tapping the Clear Data button will delete your messages so if you don’t want to lose them, make sure to create a backup before doing it. You can use Smart Switch for this task.

If the problem continues after doing the two solutions above, call your carrier to see if they can figure the cause.

Problem 5: Galaxy J7 only stays on when connected to charger, battery not working

Hi. I own a Samsung J7 which was purchased about a year ago. Yesterday the phone started switching off for no reason and would only switch on when I connected it to a charger. I was unable to use the camera function as whenever I turned the flash on and attempted to take a picture it would shut itself down. Although I discovered that I could use other applications such as Snapchat using the flash. Later on it completely shut itself down and whenever I connected it to a charger it simply showed a blinking battery. I removed the battery and tried to power it on several times but to no avail. I also switched the chargers I used on it. I hope you can help me solve this issue quickly as I will be travelling overseas in a few days! Thank you in advance! — Manek

Solution: Hi Manek. The problem is probably due to a bad battery so the only software troubleshooting that we would like you to try is battery recalibration. If that won’t work, you must get a new battery.

Here are the steps on how to recalibrate your phone’s battery:

  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.

Problem 6: Galaxy J7 keeps rebooting on its own, won’t turn back on

My issue is my phone is not turning on. I tried all easy procedures but it won’t charge battery is good (tried several batteries, new ones) and the battery is charging when i plug it in the phone. i tested that by putting a drained battery in the phone for 15-20 minutes and then touching the tip of my tongue on the edges so it charged…the screen works pretty good as well just something i can’t understand why the phone is completely dead though it shouldn’t. at first it turned off for a couple of days then turned back on on it’s own. This happened a couple of times (3-4 times) where it shuts down and then simply power back on after a couple of days or hours and works completely fine for a small period of time, maybe a day or two. but now it just won’t. i don’t think there is much more to explain. I’m a technician so anything related to dissassembling of the phone is easy for me. Just seeking your help for what might be the cause and thank you. samsung J700h prime. — Najjar.shadow_92

Solution: Hi Najjar.shadow_92. We don’t think you’ve tried using another battery so we recommend that you try that one first. If a new battery won’t help at all, consider checking the software by doing a factory reset and flashing the bootloader to stock (assuming that you’ll be able to turn the phone on somehow).

Should the phone remain unresponsive though, we say you have it replaced. In majority of cases where phones fail to boot up, the problem is caused by a bad component in the motherboard. If you’re a technician, you must try to check if the power IC is working because this is where the issue lies in a lot of boot-related problems.

Problem 7: Galaxy J7 screen cracked and won’t turn on after accidental drop

Well. I dropped my fiance’s phone and cracked the screen completely and the screen won’t turn on. We both thought the phone was done for and had already accepted that we will have to get a new one and that he has lost everything because it won’t turn on. But this morning one of his alarm that he had set started to go off. So the sound and alarm was working but nothing was on the screen. I took the battery out and put it back in and after the snooze time was up the alarm went off again. So, is there a way to get the screen to work again.. is all hope lost? I have tried all the steps I found online for trouble shooting and the screen in unresponsive to all of it. — Christy

Solution: Hi Christy. The phone is not dead at all so obviously the problem may be isolated to the screen assembly only. There’s no software solution for that so you want to have the phone repaired so the screen will be replaced. Hopefully we are right and the unnecessary shock from the drop only damaged the screen. Replacing this part should bring the phone back without further problems.

Problem 8: Galaxy J7 factory reset by itself

My device was acting fine but when I woke up this morning to check the time it said something like it needed to identify it was me. So I said okay and it started to restart. It made me go through all of these questions like what apps to save or delete and some questions you would fill out when first getting a phone. When I finished, it deleted all of my contacts, messages, app progress, photos, and more. What is going on? How can I restore what I lost? — Kylie

Solution: Hi Kylie. We can’t say for sure what prompted your phone to factory reset but we think you just factory reset your phone. Unfortunately, files (such as photos and contacts) that were saved locally, that is, data stored in the internal storage in the device and not in the cloud or some other device, are gone. There’s just no way to recover them again after a factory reset. App progress may not be gone if you have an online account for it. You simply need to log back in to your account to get them back.

Problem 9: Galaxy J7 screen has discoloration, distorted

Hi. I have a Samsung Galaxy J7 (2016). A few days ago my screen have been displaying small black horizontal lines all over my screen. The screen quality has decreased and all the words and icons looks a bit distorted. I haven’t dropped my phone since i bought it in January of this year. I don’t know if it is the new update that’s causing this or if it is hardware. The phone is working normally except for the screen issue. Please help. — Flare387

Solution: Hi Flare387. Do a factory reset and see what happens from there. If this screen problem is due to an operating system glitch or a problematic app, a factory reset should fix it. Make sure to observe how the screen works after a factory reset when there are no apps installed. If screen discoloration or quality remains problematic, you must send the phone in or have it replaced. Refer to the steps above on how to factory reset your phone.

Problem #1: Galaxy Note 5 SMS sending/receiving not working properly

Recently I have been having a few issues with my texts. Sometimes when I send texts, people aren’t receiving them at all. And there are times when I don’t receive any texts from others. In fact, I have one friend, an iPhone user, who can no longer receive any texts from me and we are forced to use Facebook Messenger. I can’t really pinpoint when this started, though I’ve noticed it more since around March or so of this year. This morning I sent a text to my roommate, and the Messages app sent half of a text from two months ago at the beginning of what I sent this morning. I have no idea why it would just pull old content and stick it right in front of a current text for no reason. I’ve read through some of your articles, but I’m not sure what really applies to my situation. and I can’t do a soft reset because you can’t remove this phone’s battery. Any questions you can provide to help me start troubleshooting would be appreciated. — Charlie

Solution: Hi Charlie. The first thing that you want to do is to ensure that this is not due to a bad app installed on your phone, or even an operating glitch that may have developed over time. To do that, do a factory reset and observe the phone for a few days. Make sure that you don’t install anything to keep your software as clean as possible.

If the same issue happens, you have to move to the next step which is to tell your carrier about it. SMS is a best effort service only, which means that your carrier (or your friend’s carrier) cannot guarantee that you will be able to send and receive SMS all the time. They can try to do that but they are not obligated to do it (we know by experience though that carriers are really good at ensuring that SMS works most of the time). That said, it’s worth letting them know that you’re having an issue and it appears that it’s not phone-related after all. The issue may be on their network or their message center not working properly. Ensure that you let them know that you’ve already tried a factory reset before calling them so they can start checking on their end right away.

For reference, these are the steps on how to factory reset your device:

  • Create a backup of your important files and contacts.
  • Turn off your Samsung Galaxy Note 5 completely.
  • Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  • Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  • Once the Android logo shows, release both the Volume Up and Home buttons.
  • The notice ‘Installing system update’ will show on the screen for 30 to 60 seconds before the Android system recovery screen is shown with its options.
  • Use the Volume Down key to highlight the option ‘Yes — delete all user data’ and press the Power key to select it.
  • When the process is complete, use the Volume Down key to highlight the option ‘Reboot system now’ and hit the Power key to restart the phone.
  • The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

Problem #2: Galaxy Note 5 screen discoloration issue

So, last night, when I tried to open my phone, I realized it stopped responding to touch, but would still work with my stylus, and that the upper left corner of the screen had purple splotches on it. They were growing in size and getting worse and worse, and I started to see a square of translucent purple that was almost as large as the screen itself. I got up this morning, and now the entire screen is black and purple. I contacted samsung and AT&T, but they were of little help. Have you heard of anyone else experiencing such catastrophic failure from a Note 5? I’ve also noticed compared to my note 3 that the battery was getting quite warm as well when charging or from heavy use. — Wesley

Solution: Hi Wesley. We’ve seen different types of screen discoloration issues due to water damage and nasty drops. If your Note 5 was exposed to water or heat, or was dropped, the purple color on the screen may only be one of the signs of a hardware malfunction. You must find a way to have the phone repaired, or better still, replaced. You may think that there’s a software solution for a screen issue you’re having but you’re mistaken. The best thing that you can do right now is to let a qualified technician check the hardware. If you’re lucky, the damage may only be isolated to the screen assembly, which is relatively easy to replace if you the right tools and know-how.

Again, there’s nothing much that we can tell on what to do as you clearly have a bad screen. Find a way to have the screen replaced and see how it works.

Problem #3: Galaxy Note 5 S-Pen not working in some portions of the screen when using OneNote

When using the S-Pen with OneNote there are areas of the screen in which the pen will not work. I am not using a case nor anything else with a magnet; magnets cause a completely different problem. The areas that don’t work are perfectly rectangular. One is in the top right area from 33mm to 43mm down and 6mm wide starting from the left edge of the screen. The second most common place is a transient area of similar dimensions in the lower right quadrant. The areas remain in the same physical location on the screen and do not scroll with the page so my guess is hardware, not software. However, I only have this issue with OneNote. If I use S Note or a drawing app the issue doesn’t happen. This is the third Note 5 I have had in the last 4 months because of this issue and the problem is the same with each phone. AT&T has been great about replacing the phones but I would really like an actual solution to the issue. — Brent

Solution: Hi Brent. If the issue only occurs when using a specific app, then your next logical step is to troubleshoot the said app itself. This is the first time we’ve heard of this issue with OneNote and we can confirm (based on our experience) that this apps works just fine in an international version of Note 5. There may be a conflict with the current firmware the phone is running and OneNote. To know for certain if this is the case is impossible since there’s no code-level test that we can do. You are left with standard troubleshooting any user can do if he/she thinks that an app is causing a problem.

Update

First, make sure that OneNote app and the operating system are running the most recent update. Updates bring about patches for known bugs so if there are more Note 5 users having the same issue out there, Microsoft should already be working on a fix for this issue. The same is true for AT&T. If this is an isolated case, we doubt you’ll get anything from updating but we still recommend it.

Delete the app’s cache and data

As far as we know, OneNote is a pretty stable application in an international version running the latest Marshmallow. We can’t say if it’s the same though when installed on a Note 5 from AT&T. Still, since we’re dealing with a single app, it won’t hurt if you clear its cache and data as a potential solution. Here’s how to do it:

  • Go to Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  • Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  • Once in there, look for OneNote app and tap it.
  • 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.
  • You should now clearly see the Clear Data and Clear Cache buttons for the application.
  • Once you’ve deleted OneNote’s cache and Data, check if the issue is still happening.

Observe the phone after a factory reset

A good way to check if this issue is due to interference from other apps is by wiping the phone clean and restoring all software settings back to default. Once you’ve done a master reset (refer to the steps above on how to do it), install the OneNote app ONLY and see how S-Pen works. If the issue won’t occur while the phone’s software is in this state, you can bet one of your apps is creating a conflict with OneNote.

Contact the developer

This option in troubleshooting is often overlooked by most users for a number of reasons, the most common being the lack of patience to wait for a reply from developers. Make sure that you contact Microsoft about this issue is you can’t isolate the cause of the problem. We strongly suggest that you visit the app’s Google Play Store page and post a review as well as send a message to the contact email provided.

Problem #4: Galaxy Note 5 won’t turn on

Hello. I have a Samsung Galaxy Note 5 on Verizon and phone never been dropped or wet or out of its Otterbox. It never got warm or anything but i was at work and i started recording some slackers at work with the phone facing out of my shirt pocket and after about 1 and a half to 2 minutes of recording i decided to stop recording and pulled the phone from my shirt pocket only to see that it is no longer powered on. Just prior to start the recording, my phone battery was 80 percent charged and will last me a little over a day on a full charge and it was at 100 percent about 2 and a half hours before i recorded that video, which was a half hour before getting to work.

I’ve tried every hard reset combination possible and also removing SD and sim card and doing it again — no sign of life when on a charger, no life when plugged to a pc. The PC don’t even know it’s been plugged in.

I have read multiple forums and tried so much but don’t know what would cause this type of error. Please help me. My phone has been babied and is flawless. Thanks. — Clayton

Solution: Hi Clayton. A smartphone not turning on is one of the most common issues we cover in this blog and we are positive that we always remind users to submit their device for repair if our suggestions don’t work. You should do the same. In some cases, a faulty power button is the only issue after a hardware check so there’s a chance that this may also be the only thing preventing your device from booting. If power button is okay, the next thing a technician checks is the battery. Since a Note 5’s battery is non-removable for an average user, the technician must remove it himself so he/she can check if it still dispenses power properly. Finally, a full motherboard check may be needed if both the battery and power button are found to be in good shape. All these things can only be done by a competent technician so we recommend that you bring the phone to Samsung or your trusted local electronics shop as soon as possible.

Problem #5: “Your connection is not private” error keeps showing when Galaxy Note 5 tries to sign in to Starbucks portal

Hello. I have a Galaxy Note 5(T-Mobile). I have been working at Starbucks for over two years now and always connected to our wi-fi just fine. Like many of our customers I never had an issue. one day, I got an error message saying “your connection is not private.” It continues to say attackers might be trying to steal your information from www.google.com (for example passwords, messages, credit card) NET::ERR_CERT_COMMON_NAME_INVAILD

I have tried to trouble shoot myself and have cleared cache, deleted browser history, checked the date and time, etc and still get the same error. This happens too at other grocery stores. I have the wifi on all the time and at home it works just fine. At my sister’s house too. I take class at a local community college and i am able to connect there too, with no issues.

I have called T-Mobile. They had me check the date and time, clear history, clear cache, etc. The last resort would be a complete restart? not sure if that is what it’s called…but they told me I would have to back everything us, which i really don’t want to do. anything else you can suggest? — Alma

Solution: Hi Alma. The error “Your connection is not private” or “NET::ERR_CERT_AUTHORITY_INVALID” or “ERR_CERT_COMMON_NAME_INVALID” is a generic error given by Google Chrome browser. This error can pop out due to several reasons that includes the following:

  1. incorrect system time, timezone, or date
  2. the website or wi-fi portal you’re trying to access via Chrome browser is detecting that connection is not private and that you may be exposing your credentials to untrusted parties.
  3. you’ve installed an antivirus app with HTTPS protection enabled, which means that any attempt of your browser to access a website with secure connection or portal is blocked.
  4. third party app that may be routing your connection to a proxy server

To resolve the issue, the first thing that you want to do is to log back in to Starbucks portal and simply ignore the error by tapping on the “proceed…” link at the bottom of the box. If that won’t fix the issue, make sure that you turn off the HTTPs protection of your antivirus app (if you have any).

You can also boot in safe mode to see if that will change anything. This is useful in preventing apps that redirects your connection to a proxy server. If you will be able to connect to a Wi-Fi portal while in safe mode, then that’s a sign that one of your apps is to blame. To fix it, uninstall app until the issue is gone. To boot in safe mode, follow these steps:

  • Turn off the phone completely.
  • Press and hold the Power key.
  • Once ‘Samsung Galaxy Note5’ shows, release the Power key and immediately press and hold the Volume Down button.
  • The phone will restart but keep the Volume Down button pressed.
  • Once the phone has finished restarting, ‘Safe mode’ will be display in the lower-left corner of the screen.
  • You may now release the Volume Down button.

Problem #6: Galaxy Note 5 audio not working

The problem has been happening for quite some time but always worked afterwards, but now it doesn’t work at all. The thing is, I can’t do anything that has to do with audio on my phone. I can’t hear audios, make videos (with my camera, on Snapchat, Instagram, nowhere). I can’t record audios, hear absolutely nothing that has audio, I can’t call (not through my phone, neither through Whatsapp, etc). I don’t know if this has to do with a message that sometimes pops up: “Google Play services ended” (or terminated, I don’t know the actual translation, it’s a German phone, so it’s all in German). Normally this message did nothing but these last months I have the feeling that everytime the message came up the audio started working. I looked up and of course the Google Play services has access to everything like camera, audio recorder etc. So I don’t know IF this is causing the actual audio problem or not. — Karin

Solution: Hi Karin. If the phone has permanently lost its ability to use its audio functionality, the first thing that you must do is factory reset. This will not only remove existing bugs but can also indirectly help you determine if a third party app is to blame. Refer to the steps above on how to do a factory reset. Once you’ve done that, observe the phone for a few hours. As usual, make sure that you don’t install anything  during this time. If audio will work, that means that one of your installed apps is the culprit. You must do a trial-and-error installation to see which of them is responsible.

However, if the phone’s audio remains problematic during the observation period, you can assume that hardware malfunction is to blame. Contact Samsung to have the phone repaired or replaced.
