Galaxy Note 3 Freezing Issues Solved

Problem: I use to have a HUGE problem with my Note 3 freezing, glitching up, and just doing the weirdest, most inconvenient things. I did multiple factory resets and had the Android 4.4.2 KitKat update reinstalled 3 times to try and fix my issues. Well, one day I was messing around and changed the keyboard from Swype to Samsung. A few days went by and I had no issues. So, I turned the Swype keyboard back on and my issues started up within the following days. I no longer use the Swype keyboard and ever since ALL my issues have stopped. I haven’t read all of the solutions you have done, so I apologize in advanced if this is “old news”. Thought I would share it though. 🙂

Solution: Thanks for this tip. Actually, one of the most common causes of issue faced by an Android device are third party apps. Most of the time when an app isn’t compatible with the latest operating system used by a device all sorts of issues pop up such as freezes, reboots, and others. You will notice this when you do a software update on your device. One best way to check if a third party app is causing the problem is to boot the device in safe mode and observe if the issue still persists.

To start this device in safe mode

  • Turn off the device.
  • Press and hold the Power/Lock key for one or two seconds to turn on the device.
  • When the Samsung logo displays, press and hold the Volume down key until the lock screen displays.
  • When the lock screen displays, Safe mode shows in the lower-left corner of the screen.

Galaxy Note 3 Cannot Use USB 3.0

Problem: Hallo, i am not able to use the usb 3.0 feature of my note 3. Plugging in the micro usb plug, it is recognized by the windows 7,8 computer. Kies 3 is installed and can connect. Back to the Note 3, I switch usb to usb 3.0.  Again Kies recognizes and connect to the phone. But then, the connection breaks down and reconnects to the PC. This is done in an endless loop. It is not possible to transfer any data. I tried this with windows 7, Windows 8, Windows 8.1 on different hardware. I also had to change the phone due to a hardware defect not related to the usb issue. So I have the same problem on any combination of platforms. Do you have any ideas?

Solution: Most owners of the Note 3 have also reported that they are also experiencing this issue. Most of the time the problem is with the supplied USB cable. Try replacing it with another USB 3.0 USB cable and see if that solves the problem. If you are still having issues when using the new cable try taking out the MicroSD card of your device then test again. A corrupt MicroSD card may also affect the USB 3.0 connection.

If the above solution does not work then try this.

  • Update the firmware of your device, do it on KIES 3.0 (download from official samsung website) if updating directly on phone does not work (settings > general tab > about device > software update).
  • Enable developer option and then enable USB debugging. (settings > general tab > about device > tap the greyed out “build number” 7 times > go back to general tab > developer option > enable USB debugging)

Now do a test again and see if your device can connect normally to a USB 3.0 port.

Galaxy Note 3 Samsung AllShare Cast Hub Blank Screen

Problem: Hi, Hope you can help me with a good idea or direction. I just bought a new Samsung Cast Hub. I have connected my Samsung Note 3. (The Note has the latest updates and ScreenMirror patches). The Note says it is connected and mirroring but the screen is blank. Now, I also have a Samsung MHL cable to mirror the screen and this connection is working with the my screen. Any idea or help? Thanks a lot.

Solution: Check and see if the procedure for connecting is correct

  • Connect your charger to the power socket of your AllShare Cast Wireless Hub: Wait for the status indicator to turn red. It may take up to five seconds for the indicator to turn red. If it fails to turn red, try to check the connection and see if there are issues with it.
  • Connect your TV and AllShare Cast Wireless Hub using an HDMI cable.
  • Adjust the source input of your HDTV, making sure that it matches the port that is used by the HDMI cable.
  • Wait for the status indicator to blink red: Usually this may take up to a minute, depending on your situation. If it won’t blink red, turn off your HDTV and AllShare Cast Wireless Hub and start all over again.
  • Once the status indicator of the Wireless Hub device blinks red, press the “Reset” button: You will then notice that the status indicator has now turned into blue.
  • You are done connecting your HDTV and AllShare Cast Wireless
  • Now go to your Samsung Galaxy Note 3: Press the “Home” button once to get to the home screen.
  • From your home screen, tap on the “Menu” button (lower-left soft button).
  • From the menu, tap on “Settings” (gear icon) to get to the settings menu.
  • From the settings menu, go to the “Connections” tab
  • On the Screen Mirroring page, tap on the slider on the upper right part of the screen to turn it ON
  • A list of available devices will now show: Select the AllShare Cast Wireless Hub from it. The name will also appear on your HDTV.
  • Wait for the connection to successfully link both devices: Your Note 3 screen will now be shared to your HDTV.
  • You have successfully shared your Galaxy Note 3’s screen to your HDTV.

Galaxy Note 3 Cannot Connect To Internet

Problem: Hi There, Just quick question, I have samsung galaxy note 3 which was in begining droping the wifi. Now it cannot connnect to internet even thought is says that it is connected to WIFI? Could you please let me know what could be a reson for it and how to rectify it. Thank you in advance.

Solution: There could be various factors involved as to why your device cannot connect to the Internet. It could be a problem with your ISP (Internet Service Provider), the router or the device itself. First verify that the Internet connection from your ISP is stable by connecting another device to your wireless network and see if that device can get online. If it can’t then you might want to contact your ISP.

Next, verify your router settings and see if it is correct. Most of the time a misconfigured router will allow a device to connect to it but won’t allow it to go online. See if the firewall setting on your router is blocking your device. It is also a good idea to reboot your router.

If your ISP and router settings don’t have a problem then it’s time to check your device. Try to forget your home network then scan for it again and add it. Check and see if you can get online. If not, you might want to start your device in safe mode and see if a third party app is causing this issue.

  • Turn off the device.
  • Press and hold the Power/Lock key for one or two seconds to turn on the device.
  • When the Samsung logo displays, press and hold the Volume down key until the lock screen displays.
  • When the lock screen displays, Safe mode shows in the lower-left corner of the screen.

Once in Safe Mode try to get online.

Galaxy Note 3 Display Gets Divided Into 9 Smaller Screens

Problem: Hey droid guy. Please I need some help from you. I bought my GN3 5 months ago and I didn’t have any problem with it. This month a problem occured several times , when I’m using my phone the screen is devided into 9 similar small screens. The touch still works. I pushed the sleep button then push it back the screen is back to one big screen. How can I solve this problem? I cant find this problem on the internet, I need your help. Thanks in advance.

Solution: Do these 9 smaller screen have the same content or do they have different content? Are you using the stock launcher of your device? If you are using a third party launcher then it is possible to have 9 home screens and if you pinch on the display you will see these 9 home screens. I’m thinking this might be what is happening to your device. What you need to do is start your device in Safe Mode and see if you are still seeing the problem. In Safe Mode any third party app gets disabled which includes any launcher that you have downloaded from the Google Play Store. If in Safe Mode the problem does not occur then you might want to uninstall the third party launcher.

If in Safe Mode the problem still occurs then the best option right now is to do a factory reset. Just make sure to backup all your important data first.

  • Turn off device
  • Press and hold the Home button Applications icon (located at the bottom) & Volume Up button (located on the left edge). With the Home and Volume buttons pressed, press and hold the Power button (located on the right edge) until Samsung logo appears then release all keys.
  • Select wipe data/factory reset. (Use the volume buttons to highlight and the Power button to select.)
  • Select Yes — delete all user data.
  • Note Allow several seconds for the factory data reset process to complete.
  • Select reboot system now.
  • Note Allow several minutes for the reboot process to complete.

Galaxy Note 3 Display Goes Black

Problem: Hello. I have looked through your posts and have found similar issues but no advice or solution. My whole family has the GN3 and 3 out of 4 phones have the same issue so I don’t think its hardware. Also it did not seam to appear until after the last AT&T update to KitKat. Here is what happens, the phone will just go black, I can hear that it is still working/running apps, the lights on the bottom bar still lights up, a phone call will still be connected (this mostly happens during calls but also during games/internet/music) so the device is working but display is black. Now I hit the power button, home button, volume, back, menus ext and display still remains black. After 5 minutes or so it will come back on let me put in my pass code and use the phone for maybe 45 seconds then go black again and come right back up so I can put in my pass code but then the screen will not respond to touch at all for a minute then it will go nuts catching up with everything I did while the screen was frozen (I hope that makes sense) and work for a while until the issues come back. After resetting the phone (while not working you can hold down power and reset (the menu for powering down options will come up but if you don’t make a choice and hit back it goes black again) then the phone will reset) and after reset the problem goes away for a while then starts kicking back in. So needless to say we reboot a lot. I have called AT&T and Samsung and they don’t seam to know about the issue or want to help or just tell me its hardware and to replace it. I know its not hardware because we have 4 GN3’s and this is happening to 3 of them in different degrees (mine is the worst). I have checked and there is not a common app between all 3 phones we all use different software and I have factory reset several times and left them stock and still the issue exists. Also on one of the phone they waited to update to KitKat and did not have the issue but after update it came forth. There is some setting in KitKat or some setting causing the issue because the 4th phone is fine and I can’t find the setting different. Thanks for what help you can give. Also if it helps I have little glitches like email/texts will stay in sending status and MMS will stick in receiving status until I switch WiFi off and on a few times or even airplane mode back to normal and then they will go through. Its strange and I am the only one that gets that. Besides that the phones work great. Thanks so much.

Solution: From the way you described the problem it appears to be caused by the KitKat update. Usually a factory reset will solve most of the glitches that occurs after an update but in your case this does not work. Have you tried booting your device in Safe Mode and see if the problem still occurs? Try doing this if you haven’t since I’m suspecting this might be caused by a third party app.

Galaxy Note 3 Audio Codec Issue

Problem: Hi, I own a galaxy note 3 n9005 in India. I guess the note 3 doesnt support the AC3 codec as when I play HD videos on it, the video plays fine but displays a message audio codec not supported. However it plays fine on mx player, no issues with sound or video. But I want my inbuilt video player to play such videos without any hassles. So is there any possibility to upgrade the phone to support AC3 codec files. Or rooting and installing any custom rom will help? Awaiting for your reply. Regards

Solution: Unfortunately unlike the Note 2 which supported the AC3 codec the Note 3 does not support it at all. The only workaround to this problem is through a software solution and that is by using a player, such as MX Player, to have it support AC3 codecs.

Galaxy Note 3 Getting Slower

Problem: I have a few problems in my note 3. 1. The phone got pretty slower in the last two mounth and i dont know why and i tried everything between uninstalling apps i dont use between closing app throw the task manager.. And all of This doesn’t helped the Phone to go faster. 2. Most of the times that i see videos in lanscape mode the video gets slower and the video doesnt stream well and its gets fixed Just when i restart the Phone but the problem is getting back all the time. Thank you for all Your help!!

Solution: When your Note 3 starts to slow down it’s time to do some maintenance work on the device. Try doing the following steps and see if it improves the performance of your device.

Take out SD card

  • From the home screen, tap the Menu key.
  • Tap Settings.
  • From the General tab, scroll to and tap Storage.
  • Scroll to and tap Unmount SD card.
  • Tap OK.
  • Remove the SD card.

Most of the time when the SD card becomes faulty it will take a long time for the device to access data on it. This usually causes the device to slow down.

Do a soft reset

  • Turn your phone off.
  • Remove the battery. After 30 seconds, reinsert the battery.
  • Turn your phone back on.

A soft reset clears out residual data stored in the RAM of your device which isn’t needed. This may cause your device to operate slowly.

Clear application cache

  • From the home screen, tap the Apps icon.
  • Tap Settings.
  • From the General tab, tap Application manager.
  • Swipe left to the All tab.
  • Scroll to and tap the desired application.
  • Tap Clear cache.
  • The application cache is now cleared.
  • Repeat procedure for the other apps

Apps often store data on cache but then when this accumulate it causes the device to slow down.

Close or uninstall applications

  • If you have applications that you don’t really need it would be a good idea to close then or uninstall them.

Update your device

  • Make sure that your device is running on the latest software.

Galaxy Note 3 Reboots Every 25 Minutes

Problem: Was wondering if you can help with phone, have upgraded to kit kat 4.4.2 an now every 15-20mins my phone shuts down an starts back up again, have cleared the cache like said but still keeps restarting every 15-20mins, so far that’s my only problem but phone isn’t on long enough to see what else is wrong.

Solution: Try doing a factory reset and see if this solves the issue. Make sure to backup all your data first before performing the procedure.

  • Turn off device
  • Press and hold the Home button Applications icon (located at the bottom) & Volume Up button (located on the left edge). With the Home and Volume buttons pressed, press and hold the Power button (located on the right edge) until Samsung logo appears then release all keys.
  • Select wipe data/factory reset. (Use the volume buttons to highlight and the Power button to select.)
  • Select Yes — delete all user data.
  • Note Allow several seconds for the factory data reset process to complete.
  • Select reboot system now.
  • Note Allow several minutes for the reboot process to complete.

Galaxy Note 3 “MicroSD card removed unexpectedly”

Problem: I have a Galaxy Note 3 from AT&T. I inserted a 64gb SD card for extra storage. Weird thing is that ever so often it gives me this error message. Any reason why? And possibly any permanent fix?

Solution: This could be a problem with the SD card or the SD card contacts on your device. Turn off your device and take out the battery and SD card. Using a cotton try cleaning the SD card contacts on your phone. Now place back the battery and SD card and turn on your device. If the problem still occurs then you might be using a faulty SD card. Try using another SD card.
