Answers.Text: It's certainly not an issue with storage or memory limitations. EV3s doesn't really suffer from those like the RCXs or NXTs do. Excellent workaround though!

Answers.Text: Thank you very much for finally warning me that my EV3 lacked this app for so many years! What I mean is, My EV3 NEVER had the Brick Datalog app on it. Right when I pulled it out out of its amazon box, I immediately explored the features of the brick and I recall knowing that there was no such app. Especially before I updated to the latest firmware, it still was never there.

  Interesting insight. I didn't notice that it was missing. (I wonder if there was not enough room in the flash memory for both this and the new MakeCode stuff - or maybe it was just an accident).
  
  I managed to find a hack to get the `Brick Datalog` program loaded again.
  
  1. Download [this](http://files.lechnology.com/lego/mindstorms/ev3/Brick%20Datalog.zip) zip file.
  2. Unzip the file.
  3. Open `Brick Datalog.ev3` in the EV3 programming software.
  4. Download the project to your EV3.
  5. Open the *Memory Browser*.
  
     [![Screenshot with arrow pointing to Open Memory Browser icon](https://i.sstatic.net/1NI2T.png)](https://i.sstatic.net/1NI2T.png)
  6. Browse to the `Brick Datalog` project, then click *Download*.
  
     [![Screenshot of the Memory Browser with arrows pointing to the Brick Datalog folder and the Download button](https://i.sstatic.net/Ey76Z.png)](https://i.sstatic.net/Ey76Z.png)
  7. Select the `Brick Datalog.rbf` file (from where you unziped the file in step 2) and click *Open*.
  
     [![Screenshot of the file Open dialog with Brick Datalog.rbf selected and an arrows pointing to the Brick Datalog.rbf file and the Open button](https://i.sstatic.net/7Giwp.png)](https://i.sstatic.net/7Giwp.png)
  8. Close the *Memory Browser*.
  9. On the EV3 brick, you can now browse to the `Brick Datalog` project and run the `Brick Datalog` program (it won't be with the rest of the "apps" as in previous versions of the firmware).
  
  How it works:
  
  The brick apps use the same format as user-created programs on the EV3, so I just took the `Brick Datalog` app from the [ev3dev lms2012-compat](https://github.com/ev3dev/lms2012-compat) project (which is identical to the official LEGO version, but easier to get to).
