Contacts won’t download, Note 4 shows “Updating contact list…”

Problem: I did the update on my phone and after it rebooted itself it everything else worked but my contacts wont download and i can’t send or receive picture messages, I took my phone to the T-Mobile store and they told me it wasn’t a service issue that it was possibly because of the update.

Troubleshooting: When you said that the contacts won’t download I assume you’re seeing the message “Updating contact list…” and that you left the phone for several minutes to a few hours already. Basically, it has something to do with the sync, so I want you to try this first:

  1. With two fingers, swipe from the top of the screen to the bottom.
  2. When Quick Settings screen appears, toggle the Sync button to Off.
  3. With master sync already disabled, reboot your phone and open the Contacts app.

And then this one…

  1. Open Contacts.
  2. Touch More options (3 dots).
  3. Choose Accounts.
  4. Choose the account where your contacts are saved.
  5. Touch More options.
  6. Tap Sync now.

Lastly, if the problem still remained, then do this. There’s, however, a catch–contacts that are saved in your phone’s memory will be lost:

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

If all else fails, do the master reset.

Related Problem: Yesterday I updated the software to the latest version 5.1.1 and since then when I go to contacts it only shows the message “updating contact list” and also my battery is running out very quickly ( I guess because the phone us trying to update the contact list all the time). I have tried all the recommendations from your article without success. Please help!

Related Problem: Contacts and call log keeps displaying updating contact list with  a loading circle it’s been over 3 days.  The contacts are saved but the names aren’t being displayed.  I know this because when I go to create a txt message the name appears but when I select it only displays the number.

Related Problem: Recently updated to Lollipop v5.1.1. since contacts refuse to update.  Have tried clearing the app cache couple of times to no avail.  Trying to avoid the hard reset, have backed up all date, but rather not go the hard reset yet. Any ideas?  Any workable suggestions would be greatly appreciated.

Note 4 started rebooting after Android 5.1.1 update

Problem: So I purchased a Note 4 SM-N910T about a year ago. It worked fine but last month shortly after the 5.1.1 update I did it started randomly restarting for no reason. First I thought it was Snapchat because I read somewhere that there are camera problems, so I stopped using it. But it kept restarting even after that. From then I have made a factory and a master reset, rooted the phone and even installed CM 12. No mater what I do it keeps on restarting. The only way to get it out of the boot loop is to connect it to a charger that is not a fast charger. Then it starts charging and works normally and you can do everything normally. After you remove it from the charger it works as long as you do not use it. When you start using it and want to do something with it, it starts restarting again.

Suggestion: So you ruled out the possibility that it was a firmware issue but apparently, it’s a battery problem. As you said, the phone won’t restart if connected to a stable power source. That’s the proof that the battery can no longer power the device up without the aid of its power adapter. It looks like replacing the battery is your best bet to make your device work again without being plugged.

Note 4 with new battery freezes when opening apps

Problem: I recently changed my battery (purchased from Samsung – genuine part) as the phone was dying at 40%. Began fine, however after a month or so, my phone began freezing on certain apps. Sometimes it would reset itself, and other times I would have to remove the battery to force reset.

Over the past few days, the problem with the phone freezing has gotten worse, happening almost every time I open any app. When I try to reset the phone, it goes into the android picture screen and says “downloading please do not turn off” – however it would never turn on. The only way to reset the phone and turn it on was to hold down the power, home and volume down key. This worked for a while but then the phone would not turn on at all. Eventually I managed to turn it back on using the previous method, however nothing was working so I did a factory reset (backed up all apps and settings and restored after the back up). This has not fixed the problem and it is still freezing and not responding. Could this be to do with the new battery or some other issue? Appreciate any feedback and help. — Antonio

Answer: The function of the battery in your phone is pretty straightforward–it powers the device on. So, no, it’s not a battery issue. In fact, I think it has something to do with one or some of your apps. The reset should have fixed it but when you RESTORED all your apps and settings, your phone starting freezing again. I am thinking maybe it’s the third-party apps that’s causing this issue and with that in mind, I need you to boot your phone ins safe mode:

  1. Turn off the phone completely.
  2. Press and hold the Power key and the Volume Down key.
  3. When the phone starts to boot, release the Power key but continue holding the Vol Down key until the phone finished restarting.
  4. Safe mode will be display at the lower left corner; you may release the Volume Down key now.

Now, while in this mode, try opening your apps to see if they still freeze and if so, the problem could be in the firmware itself or in the pre-installed apps and one of your options is to check if there’s an available update for it. Your second option is to do the master reset again but this time, DON’T RESTORE your apps, instead, download fresh copies from the Play Store.

However, if the problem was fixed in safe mode, then it must be your third-party apps or one of them that’s causing the problem. It might be difficult to find the culprit especially if you have a lot of apps installed. So, your best bet is still the master reset and try to be mindful of the apps when you install them to know which among them are causing the freezes. Here’s how you do the master reset:

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

Note 4 kept crashing after 5.1.1 update, random reboots

Problem: Official 5.1.1 update  broke the phone. always crashing etc.  So I installed with Odin a Stock ROM of 5.1.0 . All went well, managed to reinstall my apps etc. Phone still crash and hangs, but much less than with 5.1.1. BUT it has crashed at least 2 times while unable to reboot (and showing the Could not normal boot ddi:mmc_read failed) …and I get over it by booting in download mode, press up to restart the phone, then it starts normally. I just want to have and idea what could cause this? Thanks.

Answer: No one knows for sure what the cause of the MMC read failure is but it seems to be so common especially with Sprint variants. So, I’m thinking that it’s not the firmware that has an issue but the hardware itself. Perhaps a bad batch. I’m glad you found a way to work around the issue but sad to say that neither Samsung nor your provider can help you fix it.

Note 4 won’t boot up, shows “Downloading…Do not turn off target!”

Problem: My phone often got stuck at e boot up Samsung logo. And also occasionally, it will show the green android on screen & below it states “Downloading target. Do not switch off device”. At the same time, at the top left hand corner of the screen states a series of text with one of them saying “boot up failed”. Need help with these issues. Unable to turn on my phone more often than not.

Solution: You can actually just turn the phone off and on again and it should boot up normally provided that you’re not pressing other keys except the Power button during startup. If that won’t work then here’s one trick a lot of people think is absurd but very effective:

  1. Remove the battery.
  2. Press and hold the Power key for 30 seconds.
  3. Re-place the battery.
  4. Turn the phone back on.

Well, try it!
