Legion Go Update 01.19.24

Hi All,

Since we had a relatively large update last week content-wise and most of those improvements are still scheduled to be rolled out over the next 1-2 weeks I'll keep this week relatively brief. If you want to read up on our short-term roadmap, priorities, actions, known issues, etc. please reference last week's post here: Legion Go Update 01.12.24 | Lenovo Gaming (UK)

For this week, couple of new things/updates: 

SD Reader Stutter/Lag

We are collectively working between Lenovo, ODM, RealTek, and the community on diagnosing the SD reader lag and stutter some of you are experiencing.

From what we've gathered so far...

  • RealTek SD reader seems to be more affected than Genesys although we're getting reports of the issue on both now.
  • Difficult to diagnose and pinpoint root cause as there are so many factors in play and everyone's situation is unique (what they're using, their settings, SD cards, quality and spec of the SD cards, etc.)
  • Some users have found relief by disabling Modern Standby
  • UHS-I cards seem more affected than UHS-II but understand the UHS-II are a bit price prohibitive and more performant.  Just providing this info as an additional data point.
  • Going to see if I can get permission from RealTek to release an updated driver I have that may help alleviate (though admittedly unlikely to completely resolve) some of the issue as well

Thanks to Lehik0, Tokoat, Martog, GhostFella, pixelcowboy for all their contributions and support on this as we work to identify the cause.  These folks are sacrificing a lot of their time to help diagnose and root cause this issue and provide data to Lenovo and RealTek and we're extremely appreciative.

Controller Calibration

Some of you mentioned controller calibration is hanging/not completing properly.  There was a new Calibration process implemented for the controllers with the FW update from last week.


  1. Press LT and LS (or RT/RS) simultaneously until the joystick light turns to a blue swirl indicating the Joystick is ready for calibration being careful not to press any other buttons.
  2. Move the joystick out to the farthest position possible and rotate in a circle 2-3 revolutions
  3. Let the joystick return to it's resting position
  4. Tap the LT (or RT) button twice to signal completion.
  5. Controller will then enter Gyro calibration mode
  6. Joystick RGB ring will flash red while the controller is moving, flash green while still
  7. Keep the controller still to end calibration (solid green light)
  8. You'll feel (if enabled in settings) two vibration pulses from the controller once complete.  If you have disabled controller vibration the light will just go back to whatever your original RGB settings were.


  • Process is the same for both controllers. Just use LT/LS and RT/RS accordingly
  • The latest firmware is required for this process to take effect and is RX:0231220A L:0231226B R:0231226B
    • Your current FW version can be found in Legion Space.  Select "controller" from the left menu and scroll all the way down and they are listed under "Current Controller Version"
    • Press the "Check for Updates" button to ensure you are on the latest version 

3D Files

We've been working on getting something to a releasable state for a while, there is admittedly still some work to be done on it but wanted to get what we have out.  What we have is a draft prototype for an adjustable controller holder as well as pogo pin covers that are 3D printable.  This should at least give you the rail designs to work with for other projects you may want to pursue.  We're not "licensing" the files in any way, they were designed with the intention to provide the community to tinker with. We will be launching an official controller connector at some point (not based on this design) as well.

You can check out the available files here: Legion Go Controller Connector 3D Files | Lenovo Gaming (US)

This may be all we get for a while, but I will continue to explore opportunities to provide more.

Upcoming Major Updates

  1. Space (tentatively
  2. V29 BIOS
  3. SW/FW/Driver Update Delivery

Details in previous post from January 5th here: Legion Go Update 01.05.2024 | Lenovo Gaming (UK)

All of these major updates mentioned in the last couple of updates (Space, Service, BIOS) are (as of today) still on track for release in the next 1-2 weeks.

Thanks as always for your continued support and interest in the product.
