I just got myself a powerA bluetooth gamecube controller for the nintendo switch, and I wanted to use it with my new oneplus 7 pro to play dolphin.
The thing is that button mapping for switch pro controllers is now part of android 10, but I still had that horrible 1sec latency from the phone, making it unusable.
I looked for a few days online, finding solutions that required you to modify bluetooth lib files, but nothing for android 10 that was working on oneplus phones.
I finally found it on GBATemp, posted by Dracker on a post about Joycons lag.
You need your phone to be rooted, so you can access system files.
-
Get a root file manager, I personally used Root File Manager: https://play.google.com/store/apps/details?id=com.acr.rootfilemanager
-
Get a Hex editor, i used HEX Editor: https://play.google.com/store/apps/details?id=com.myprog.hexedit
-
With the file manager, navigate to /System/lib64/ and copy the file named libbluetooth_qti.so.
-
Paste it to another location on your regular storage, that will be your backup file in case you mess up. DO NOT MODIFY IT.
-
Shutdown bluetooth. Open HEX Editor, Go to settings -> Root options and activate root mode. Close the app and open it again, you will be asked for root permission. Now choose internal storage and go back to /System/lib64 and open libbluetooth_qti.so.
-
Click the magnifying glass and search for 09648052 (Be sure that you are looking for "Hex fragment".)
-
It should get highlighted. Click the 64 from 09648053 and use the pen button from the bottom to modify it with 00.
-
Check that it is correctly modified, and then close everything.
-
Turn on bluetooth and connect that laggy controller, should work fine!
That might work on other Android 10 phones, or other oneplus phones, I cannot test it, if someone gets it to work somewhere else, post it here :)
