After updating my phone (S20 FE / SM-G780G) to OneUI 4 / Android 12, I couldn't use my Playstation DualSense controller properly with the phone anymore.
Some of the keybindings for it are completely wrong. For instance, when I press "triangle" I get the action mapped to "L1" in game. "X" gives me the action for "circle", etc. Worst of all, the right analog stick axis is mapped to L2 and R2 triggers, while the L2 and R2 are mapped to right analog axis.
After investigating the issue, I've found that the keylayout file for the controller is wrong. The file is located at /system/usr/keylayout/Vendor_054c_Product_0ce6.kl
To conclude that it's wrong, I've compared the keycodes the controller generates when it's plugged in to my PC to those mapped to the file. The mismatched mappings are consistent to the faults I'm experiencing.
I hope this will get fixed in future patches. As far as I have searched, this is an issue affecting many Samsung phones on Android 12.

Hello, Everyone. I definitely understand the frustration with the controller not working properly with your galaxy devices. In honesty, because the controller is a third-party device, It's hard for us to provide any troubleshooting for this particular matter.
For connectivity issues, we recommend checking out the following article: https://www.samsung.com/us/support/troubleshooting/TSG01208950/
For connection, instructions check out the following article: https://www.samsung.com/us/support/answer/ANS00087582/
In regards to the mapping not aligning properly, we can only recommend making sure that everything is up to date on the phone itself software-wise. It could be the developer of the emulator as well depending on what you're using. There are a bunch of different aspects that would have to be considered.
The only other thing We can recommend is to submit an error report to alert our engineers.
To do this, please try the following steps:
• Long press the Samsung Members icon on the Apps screen and Tap Error reports.
• Tap OK on the agreement popup for sending system log data.
• Select Symptom category.
• Describe the problem in detail and SEND.
Digging a little bit more, I've found this issue from a frustrated developer who also noticed broken behavior of the controller in his Galaxy S10 after updating. Instead of implementing the newer Android 12 DualSense drivers with support for features like Gyro and touchpad, Samsung actually broke everything related to the controller. Now we don't have the advanced features, neither the basic functionality.
As it's visible in the link, the problem is not present in AOSP Android 12.
It looks like the "incorrect DualSense mapping" aspect has moved into a different issue.
For what it's worth, I can confirm that I am also experiencing the incorrect DualSense mappings on my Samsung Galaxy S20 FE 5G (model number SM-G781W, Canadian).
Got an update to oneUI 4.1 today. Mappings are still broken, but in another way. And i've installed gamepad tester app with 2 different types of testing for dualshock/dualsense controllers. And on 2nd type it works fine! Now the problem is, how to switch device to 2nd type bindings :C
Thank you for raising awareness for the Dualsense button mapping issue. Any chance Samsung will fix this? I really want to play PS5 via remote play on my Note 20 Ultra...
