Disc would eject by itself… ever when i have the ps4 off
I came across this problem. I do not have a 100% fix but this fixed mine for about two months but I repeasted this and now my PS4 is okay. First make sure the surface it is situated nothing is making contact with the eject button. Next power off the PS4 and unplug the power supply for about 30 seconds. Once plugged back in your PS4 should hopefully be fixed.
