I discovered this issue after 3 months of owning the console. It started ejecting constantly, even though there was no disc inside the ps4 tray. This problem has also occured when the ps4 has been shut off completely, and ends up turning itself on via this method. If I unplug the cabling, try to power it on, it will turn on for a couple of seconds before turning itself off again (obviously, no power) and this method helps drain any excess power stored inside the console, which MIGHT be causing a static charge build up which in turn is triggering the touch sensative buttons spontaneously.
I emailed sony about this issue and the irish gentleman on the other end asked for my email adress and sent me the following troubleshooting guide;

Dear Rowan,(nyaww)

Thank you for contacting PlayStation Support.

We are sorry to hear about the issues you are experiencing with your PlayStation 4.

There is a few troubleshooting steps we suggest to resolve this problem:

Beneath the eject button on the PS4 is a small plastic foot that can occasionally move forward during operational use, push this foot back to make sure it is clear and not jamming the eject button.


Alternatively, Remove the power cord from the console and leave it disconnected for at least 3 minutes before reconnecting the power cord to the PS4 and power up normally.

Should these options fail to stop this from happening follow the instructions below:

There is a manual eject screw that you will need to use a screw driver to tighten to stop this from happening.

Step 1: Remove the glossy section of the cover

Turn off the PS4.
Unplug the power, HDMI, and any other cables from the back of your PS4 system.
On a clean, flat, surface place the PS4 in front of you so the front of the system is on the left. (The PS logo on the top of the PS4 should be right side up.)
Place you palms on the glossy panel and let your fingers rest on the far side of the console.
Apply moderate, even pressure near the seam with your palms, and using your fingers as leverage, slide the glossy panel away from you.
A click will be heard, and the panel will move about 1/4". Lift the panel off starting from the left side.

Step 2: Locate the manual eject screw & turn clockwise

With the glossy panel removed, you will see two sets of vents lining the outer left edge. Follow the slot from the front locate the first "single" slot (it's the slot not grouped with any other slots) in the vent.
Shine a light down through this slot to locate the manual eject screw
Slide the small screw driver into the vent slot and turn the screw clockwise. This may take 3-6 rotations of the screw. Very little effort is required to turn the screw.

Step 3: Put everything back together

Replace the glossy panel. Place it over the exposed section of the PS4, about 1/4 of inch away from the seam. Then, slide the panel towards seam until it clicks into place.
Connect the HDMI, power, and any other cables that were disconnected in Step 1.
Power on the PS4 to make sure everything is functioning properly.

There is a visual guide on where the screw is located below. Please only use this as a reference to locate the screw and follow the instructions written in this email.

Have any of you experienced this issue before? I havnt yet tried tightening the screw or removing the rubber foot, but my method seems to work consistently for about a month or two at a time without the issue, which is quite good but not really ideal since I dont like worrying about my game randomly stopping and losing all my progress.
