Problem #1: T-Mobile Galaxy Note 4 sends MMS right away when text or photo is attached

When using stock message app if I attach a picture or type a text it automatically sends it. I’ve factory reset, went into recovery mode and wipe data, wipe cache, even put in Odin mode and re-downloaded the software again. My phone is T-Mobile Note 4 SM-N910T3 and this is the second Marshmallow upgrade. On the first Marshmallow upgrade I could go back to Lollipop but I found out on this one I can’t downgrade. I start to use YAATA SMS for messages and have no problems I also contacted T-Mobile and did all the solutions the tech gave me. — Bobby

Solution: Hi Bobby. This issue can only be resolved by your carrier as the cause is due to their firmware. If this problem only happens when using the native messaging app, make sure to report the issue to your carrier so they can release a software fix. In the meantime, try to continue using a third party messaging app until the issue has been resolved.

Problem #2: Galaxy Note 4 won’t send text and photo together in one MMS message

Just wanted to let you know of a problem even though there’s nothing you can do but be aware. A HUGE Samsung download happened last Wed. 9/14. Since then my text messages sent with an attached photo (click on paperclip and choose take picture) transmit separately. That means the words and the photo no longer transmit as ONE seamless message — they are 2 separate messages. To make matters WORSE, the text words usually arrive FIRST WITH A 4 MINUTE LAG TIME FOR THE PHOTO. I tried this while having someone on the line and when I sent the text message the first thing they said is: “I didn’t get the photo!” F-O-U-R minutes later the photo arrived (even though it was time stamped the same as the text message.) WOW! What an awful system! We have gone BACKWARDS in ease of use. SHAME on SAMSUNG! — Joanie

Solution: Hi Joanie. As mentioned above, this is not a Samsung issue but on the coding of the firmware update that you install. We’ve observed a similar issue with AT&T and T-Mobile when they released a particular version of Lollipop before so we know that Samsung has nothing to do with it. If it’s a Samsung issue, all Note 4 users will be flooding our blog with similar reports. Just like what we tell Bobby above, try to use a third party messaging app temporarily until your carrier can release a patch.

Problem #3: Galaxy Note 4 won’t read SD card after a failed files transfer

Hi. I am using a Samsung Galaxy Note 4 mobile phone. I ordered a new 128 GB micro SD Card since I was reaching the full capacity of internal storage. When I installed that card, it was detected by the phone automatically. I formatted the card and made the setting for encryption with a password. I transferred the photos, music and some other files using “My Files” app to the SD Card which was done successfully. When I started transferring Whatsapp media, after a while I came back and noticed that the process was stopped by itself, I thought the transfer is finished. Whereas I checked and found out that it’s not detecting SD card anymore.

I removed the card and reinserted but it won’t detect the SD card. I followed some of the instructions on this site i.e. removed the card and battery and held the power button for 1min and then started the phone again but it’s not detecting the SD Card. Don’t know what went wrong but I can’t see the SD card at all and the files I already transferred to it. It has Android Version 6.0.1 Please can you help. — Umesh

Solution: Hi Umesh. It’s impossible to know for sure what went wrong with the SD card so the best thing that you can do right now is to see if another device can still read it. We know you encrypted it before so there’s very little chance that you’ll get something positive when inserting it to another device though. If another device like a computer will still be able to read the card for some reason, then make sure that you create a backup of your files right away. In the event that the second device won’t detect and read your SD card as expected, then re-insert it to your Note 4 and reformat it. Doing so will wipe the SD card clean but it’s the only thing that you can do to make it usable again.

Problem #4: Galaxy Note 4 refuses to turn on when battery level reaches 30%

Hi! I’ve been having issues with my Note 4. It turns off at 30-40 percent then when i turn it on, it’s completely zero percent. This is already after having it serviced at the Samsung service center and explained to them my battery issue AND after buying a new battery pack, thinking that maybe it was a battery issue (having had the same problem with the stock battery before having it “fixed” by Samsung service center).

Also, when i had it fixed at Samsung, they only did a factory reset since they said my phone had NO issue at all. They said my battery was working fine. But why is it doing the same thing again? I’d really appreciate any help i get. Thank you so much! 🙂 — Jasmine

Solution: Hi Jasmine. Since Samsung has already checked your phone before, you must start looking at other factors that can also alter power management behavior in a smartphone. You can begin your quest by checking if one or some of your apps is to blame. The simplest thing that you can try first is by booting your phone in safe mode. Booting Galaxy Note 4 in safe mode will temporarily disable all third-party or download apps leaving pre-installed ones and core services running. This procedure can help you determine which of your apps is causing a problem. To do that, follow these steps:

  • Turn off the phone completely.
  • Press and hold the Power key and the Volume Down key.
  • When the phone starts to boot, release the Power key but continue holding the Volume Down key until the phone finished restarting.
  • Safe mode will be display at the lower left corner; you may release the Volume Down key now.
  • Keep in mind that safe mode blocks third party apps and services. You need to observe your phone while in safe mode for at least a few days to see the difference. If the issue won’t occur, then that’s a clear sign that one of your apps is the reason.
  • You must uninstall third party apps until the issue is eliminated.

Should nothing change while the phone is in safe mode, don’t hesitate to perform a factory reset. Just like in safe mode, make sure that you observe the phone for a couple of days after a factory reset to see any difference. Also, ensure that you don’t re-install your apps or install anything new during this time. To factory reset your Note 4, follow these steps:

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

If the phone behaves exactly the same after a factory reset, find a way to have the phone replaced. There may be a hardware malfunction causing the phone to mismanage or misread battery content.

Problem #5: Galaxy Note 4 stuck in safe mode

I’m finally getting rid of my Samsung Galaxy Note 4. Today I attempted (I think I was successful) to do the soft and hard reset of the phone since I wanted to clear up a few things (like the battery dying way too fast and the Touch Wiz thing and how it freezes all the time, etc.) Plus I needed to clear all of my personal data out of there. 

Now I have a bigger problem though. My phone is stuck in safe mode PLUS it is stuck on a page titled EULA Diagnostic Tool page. It is trying to get my name etc. entered in that phone and a lot of other crap. I’ve done everything you’ve suggested. It still is stuck on that EULA page but I don’t see the safe mode on in icon. HELP!!! I need to get this phone in the mail as I sold it (for parts only…I said it couldn’t be depended on and sold it really cheap) and I have spoken with the lady who bought it and I told her the truth. I used this phone despite all of its annoying problems for over 2 years. I enjoyed the camera and the big screen and the graphics. I didn’t enjoy how people on the other end of the line never could hear me or how it dropped calls or froze. I am afraid it was in much better shape before I messed with it. HELP HELP Heeeellllllppppp! — Teri

Solution: Hi Teri. We don’t know what exactly you did on your phone so we can’t say for certain why your phone is now stuck in “safe mode.” normally, you can revert to normal mode by simply restarting the phone. If that’s not happening even after removing the battery from the unit, your only other options are to either boot the phone in Recovery mode or Download mode. Other than these, there’s no way to force the phone back to normal mode.

Boot in Recovery mode:

  • Charge the phone for at least 30 minutes.
  • Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  • When the Samsung Galaxy Note 4 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.’
  • You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  • Charge the phone for at least 30 minutes.
  • Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  • When the Samsung Galaxy Note 4  shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  • Wait until the Download screen appears.
  • 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.
  • Use Google to look for a guide on how to do it.

Problem #6: Galaxy Note 4 can’t send SMS

Hello. So I transferred my SIM card from an HTC1 MAXX to the Galaxy Note 4. Successfully connected to the T-Mobile carrier telecom in Germany and was able to receive and call out, receive texts and return texts, download and use all apps. Shortly after I received a message saying we weren’t able to sync to Verizon’s integrated messaging service. I paid it no mind because I was using a texting application. But a day or so later I attempted to text with the phones default texting apps and it failed. I can receive texts, and calls and make calls out but I just can’t text out. I changed the phone to the Samsung messaging, still fails. Cleared cache and data on both default messaging programs still can’t text out. When I attempted to sync integrated messaging it obviously didn’t work since I’m in a T-mobile/telecom carrier. So how do I make it so that I may text using the actually phone messaging systems and not a secondary downloaded app? Thank you. — Anthony

Solution: Hi Anthony. The only thing that you can check on your end is to ensure that the phone uses the correct message service center. It is the main responsibility of a carrier’s message center to send customer’s SMS to the correct recipient. Some update or app may have changed it for some reason so you have to make sure you enter it manually. You can do that by doing the following:

  • Tap Messages.
  • Tap the menu icon.
  • Tap Settings.
  • Tap Text messages.
  • Tap Message center and enter the correct information.

If you don’t know the correct message center number of your carrier, make sure to give them a call.

Now, if changing the message center number won’t change anything, you have to work with your carrier so they can check their system as well as guide you on what to check on your phone (if there’s anything else).
