Help please , is there a Bluetooth gamepad Android samsung el-gp20, and phone sony xperia c2305 . The phone detects the controller as a keyboard and mouse does not work properly . describe how I plug - in the phone include Bluetooth , include the controller , the controller sees the phone , click pair , after a few seconds the message in app settings error click OK , threw it in the settings menu (gamepad not working) , again I go to the Bluetooth menu , press the pairing , where is written the name of the device says connecting and a window POPs up with the error the application bluetooth an error has occurred. click OK , then writes that the device is connected , responsive and appear 2 notice wireless device (click to disconnect ) and the select a layout (click to select keyboard layout ) . Appeared on the screen cursor (like when you connect a mouse via otg cable ) turn the right stick to move the cursor (in any direction ) . The buttons also react button with one point opens the blind (because the cursor at the top of the screen , I think that this button is the left mouse button ) , buttons with 3 and 2 points doesn't react at all , button with 4 points makes something like a selection screen (a blue square appears almost the entire screen ) , the buttons L , R , play , start , select, and right stick with the d-pad do not respond at all . Question - is it possible to configure this controller to operate correctly with programs , or to write a driver that eliminated the need for storronden the software and how it can be done ?
