  1. I can't find the s memo on my SM T310. There's the S planner, where I can enter a memo, and there's the T memo which is text memo, but I can't find your S Memo app.

    1. Hi Genie White,
      Thanks for coming.
      CMIIW, so is it a Samsung Galaxy Tab 3.8.0?
      If so, you can find S Memo in the application menu, it's usually named as "Memo" and the icon is displayed as the "square with the letter T inside" icon.
      Hope this helps :)

      Thanks for coming.
      Theoretically, you won't be able to open a locked S Memo file in your phone without entering PIN/Password. But, I've just found a trick to read content in a locked S Memo. Here are the steps:
      1. Connect your phone to PC.
      2. If you use Windows PC, open Windows explorer then navigate to your Phone drive.
      3. Open Phone/Application/SMemo/cache folder.
      4. Copy all files in this folder to your PC and then open these files using Windows Photo Viewer.
      5. Now, you should be able to view your S Memo contents (either it's locked or not).

    3. Hi Ruba Joo,
      Thanks for coming.
      Did you ask for the meaning of "connect your phone to PC" in my reply in the Alyssa's comment?
      If so, the meaning of "connect your phone to PC" is plugging the micro USB cable into the micro USB port at the bottom side of your phone and then plug the other end to the USB port in your PC to make them connect so that you can transfer files between your phone and PC.

      Thanks for coming.
      If you didn't put any pin/password on your S Memo file, then you don't need unlock it to open it. Simply open the S Memo app and then tap the required S Memo file to open it.

    1. Hi R.L.Sampath Kumar,
      Thanks for coming and I'm sorry for so late answer.
      Sadly to say that now S Memo no longer saves the memos as .png files. It now saves them as .sfm files. That's why I have to confirm that the steps to see a locked memo in my reply for Alyssa Fortier's comment can no longer be used.
      FYI, I've tried to open a .sfm file using some apps in my PC but to no avail. If you have or can find an app that can handle .sfm file, you can try opening a locked memo in that app.

    1. Hi Bachar,
      Thanks for coming.
      Kindly do the following steps:
      1. Open My Files app.
      2. Tap "Device storage".
      3. Tap "Application".
      4. Tap "SMemo".
      5. Tap "Cache" and then copy all files inside this folder to your PC.
      6. Once done, see the extension of the copied files on your PC. If the files are saved as .png files then you can open them using any image viewer app in your PC even when they're locked. If the files are saved as .sfm files then you may have to try finding and installing an app that can open these files on your PC.

      FYI, when my S4 was still using Android 4.3 Jelly Bean, all S Memo files were saved as .png files. But, when my phone was updated to Android 4.4.2 Kitkat, all S Memo files were saved .sfm files. I myself have tried finding an app that could open .sfm files, but I found nothing.

  7. Hi,
    My phone is S Duos 2 (Model GT-S7582). I'm confused about the S/T Memo but I think mine is T Memo. Based on that, can someone help how to recover forgotten password on my memo? Or if there's no way to recover it, I would like to remove the password if possible. Thanks

      Try the following steps to recover your locked memo:
      1. Open My Files app.
      2. Tap "Device storage".
      3. Tap "Application" folder.
      4. Tap "SMemo" folder.
      5. Tap "cache" folder. This folder contains with your memo cache. If the file extension is .png, copy the required memo cache to your PC and then open it with the Windows viewer app to view your memo without entering the password. But, if the file extension is .sfm then there's no way to open your locked memo without entering the password.

    1. Hi Shahzeb Saif,
      Thanks for coming.
      Since I don't have a Samsung Galaxy starpro, I can't help you much. But, if you don't mind, you can try performing the steps within my reply for Bernice Reyes' comment in your phone. The point is if memo caches in your phone are saved in .png files then you can retrieve its contents by viewing it in the Windows viewer in a Windows PC.

  11. For those of you wondering how to get that memo you locked, not for nefarious purposes I suppose, here are some steps for S Memo. Root the phone. Towelroot is an easy way to do that. Get Root Browser. Navigate to data/sata/com.sec.android.widgetapp.diotek.smemo/sharedprefs. It may or may not be in this location depending on your phone. Just dig around in all the data folders until you find the memo app and get lucky. Open Common_setting.xml. There I found string "PREF_APPLOCK_PIN" and the pin in cleartext next to it. This would be much easier if you were able to search for that string from the parent directory. Some browser apps or if you figure out how to browse from your computer may let you do that.
