Bluetooth mouse left click button error

I have one OPPO phone，two OPPO pads，and two Bluetooth mouses.

all mouses left click button doesn't work in all OPPO pads.but they work well in OPPO phone.
when u click or hold left button,mouse cursor can't move,right button doesn't have same situation.Only when you click the left button continuously can the mouse react.In fact, I found that if I move the mouse cursor first, and then click the left button during the movement, the left button function can also be triggered.In fact, continuous clicking can respond because the mouse is also moving during continuous clicking, so the left button function can be triggered occasionally.Moving the cursor and clicking the left button can trigger the left button function 100%, and there is only a 50% probability of continuous clicking, so this should be just an OPPOpad problem. I don't know if you have a clue to solve it.thank you

The report names no files, tests, or entry points. First reproduce the left-click failure on the OPPO pads with Android 11, comparing stationary clicks, continuous clicks, and clicks while moving; done means left-click actions respond reliably without requiring cursor movement.
