Hey everyone i have made a remote using the nrf24L01 module( arduino nano, 4 analog buttons and a joystick) and powered it using a 18650 2000mah 3c lipo cell. The remote worked fine and was transmitting the signals correctly.  
I wanted to add a display to the remote so i used a 0.96'' oled display and started facing problems. I dont know why but the transmission is having some problems it sometimes transmits and sometimes it doesnt. I thought the power supply is falling short so i added another lipo cell but its all the same. Are the libraries adafruit ssd1306 and rf libraries conflicting?  
I have attahed the code for reference.
