PS4 disc reading issues occurring from update 2.55

There are reports of PS4 disc reading issues occurring since the release of update 2.55.
Although major PS4 updates only come every so often, Sony is known for releasing smaller updates in the interim.
The majority are touted as “stability updates” or for minor bug fixes, but the latest update 2.55 is actually causing issues for some PS4 gamers.
Software update 2.55, which Sony said made improvements to the software, is causing issues with the PS4 failing to read discs.
The problem reportedly occurs when the PS4 is in rest mode and is awakened by you opening the disc tray and inserting a new game or Blu-ray disc.
If you haven’t put a new disc in your system since July 1 you won’t have had the issue, and unless you’ve done this exact thing, you might not have had to deal with it either.

Thankfully this strange bug doesn’t break your PS4 in any way, it’s just a minor convenience.
However, it is a little irritating, so here’s a few quick fixes:
Don’t put the PS4 back into rest mode
Turn off your PS4 entirely, boot it back up and then you’ll be able to play or install the content from the disc as normal. We recommend you wait around a minute before turning it back on again.
Check the disc
Although the problems has been mostly connected to the software update, you might just want to double check the disc for any issues such as scratches or fingerprints if it happens repeatedly. After all, a marred disc can actually cause damage to your PS4.
Rebuild the PS4 database
This is very much for those who are having serious disc reading problems and have found the above two fixes insufficient. You can rebuilt the PS4 database, which is similar to defragging your PC, to try and combat the problems.
You do this by completely shutting down and unplugging the PS4 first. When you plug it all back in again, hold down the power button until the PS4 makes a second beep to indicate it is booting up in Safe Mode.
The fifth option in the Safe Mode menu lets you rebuild the PS4 database, which can take a bit of time. Make sure not to turn your PS4 off during the process either as this can cause major issues.
