Problem 1: Galaxy J3 events in S Planner app disappear

Hi. Had this J3 for several months. When I enter upcoming events in my S Planner calendar, it shows all programmed future events and most last 50 to 60 day events. However, earlier events keep dropping off my calendar. I need to track all of my past events going back 18 months. I tried entering an event, then saving, then editing the event and REPEAT – YEARLY – etc. but that just schedules the same event every year, when that specific event may or may not take place every year. I need a fix to save the events I enter from my phone or sync from my laptop for more than 18 months. Thank you. — Lloyd

Solution: Hi Lloyd. Samsung S Planner app only works forward (as it’s name implies) and does not readily allows you to check on past events. The current S Planner version also only shows events you’ve created for the current year. If you want to check on past events, like those  you’ve created for the past year, try changing your phone’s date and time first. Here’s how:

  1. Open Settings app.
  2. Tap Date and time.
  3. Turn off Automatic date and time (if you’re using it).
  4. Tap Set date.
  5. Change the year to the one you want.

Once you’ve changed the year in your phone, relaunch the S Planner app (be sure to close it if it’s running, then open it again to allow the new date to reflect in the app). After opening the S Planner, tap the Month-Year option at the top left side. Then, tap Year to so you can pick the months you want to check.

If the workaround above won’t show you the events you’re missing, you’re out of luck. It means that the current S Planner app did not keep the data for some reason.

If you want to keep your events and view past ones in the future, we recommend that you use either Google’s Calendar, or Samsung’s own Calendar app. Both of them support cloud upload feature so you can keep your events and other data in the cloud for future reference.

Problem 2: Galaxy J3 stuck in Samsung logo screen, won’t boot normally

Hello. I appreciate your help. I have a Samsung Galaxy J3. I know this because what I turn on my phone it will boot up to the screen that says this and then if freezes. The rest of the boot up fails and the phone is stuck.  I have looked at your site and tried the battery pull and then restart procedure and that did not work. I tried booting up in safe mode and that did not work. I tried booting up in recovery mode and that did not work either. With the recovery mode attempt, what happened is that it will vibrate then it will go to the same screen as above but there will be blue text that says Recovery booting… in blue color and very small. If I continue to hold the volume up and the home buttons it will cycle between this and then turning off and trying to reboot again. Each time it gets to the Recovery booting… part it then shuts off and the cycle repeats. If I let go of all the buttons it just goes back to the same screen and freezes. Is there anything else I can try? — Ernie Severn

Solution: Hi Ernie. The only remaining option for you right now is to try to restart the phone to Odin or Download mode and see if you can restart the phone normally afterwards. If the restart attempt via Download mode still fails, you can then try to reflash the bootloader and/or firmware. This is the last step that you can do at your level. If reflashing the bootloader won’t work at all, you can assume that bad hardware is to blame. Keep in mind that an issue like this can not be caused by a software glitch alone. At times, a malfunctioning power management IC or a corrupted memory can lead to boot problems as well. What you did differently before this problem started to occur should be the key to understanding the root of the problem but since you did not provide any history, there’s nothing much that we can say. Unfortunately, if you think it’s a bad hardware issue, you’ll most likely end up with a motherboard replacement, which, given the price of this device, can be a bit too much. It’s still up to you if you’ll eventually go ahead with a board replacement but a much better option is to simply get a new unit.

For reference, below are the steps on how to flash a bootloader of a Samsung device. The exact steps may vary a little so you should consult other guides. Remember, flashing is a risky procedure and can cause serious software problems if not done correctly. Be sure to do more research about flashing before doing it. Also, our brief guide assumes a few things such as user mastery of a computer, knowledge on what software to use, among other things.

The steps below are merely to show you how it’s done. Do it at your own risk.

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

Problem 3: Galaxy J3 email subfolders are missing in email app

Hello, Thank goodness I have found you! I have just bought a new Samsung Galaxy J3 to replace my somewhat knackered S4 mini.

I have managed to set up my email account and can see all of the emails in my inbox (albeit only sent items I have sent from the new device appear – but this doesn’t matter). What is bothering me is that I can’t see emails I had previously stored in my custom folders (sub-folders in my inbox). The message I get is: “You may have emails that have not yet been downloaded from the server.”Can you help me to get them from the server please? My incoming server settings are currently IMAP server:, security type: none, port: 143 and outgoing settings are: AM TO server:, security type: TKS, port 587.

I have tried a few different settings based on what I have found on the net but they don’t seem to work at all. I wondered if I should delete the account and try to set it up again, or do you have any better ideas please? Many thanks. — Claire.moy

Solution: Hi Claire. If the organization of your folders does not show in the current email app, that means that such format is not supported by said app. In today’s digital world, not everything is compatible so an arrangement you’ve set for your email folders may not be carried over to another device or application, like the email app you’re using. Try using another email app like Gmail app or similar and see if your subfolders will be shown as you want.
