Over time our controller buttons wear out even when we don't realize it.

Most common problem is the R2 trigger, it still works in most game but in certain game the spoiled R2 trigger can result in unplayable games. By R2 trigger spoiled I mean when we fully depress the R2 trigger, we don't get the full press input as in pristine new controller, in racing games this will result in you cannot fully accelerate (you may not realize this), in some games the gun doesn't fire at all with the trigger.

Here's what what I encountered so far, please share your encounter here to help others.

The Crew (racing game)
Problem: spoiled R2 caused player unable to fully accelerate, hence getting the wrong impression that the game is too tough or the AI too fast for you to catch up (can't even pass the game prologue). I see many players giving up on the game in online comment without realizing it's their controller problem.
Solution: Go to game setting and adjust the trigger sensitivity to maximum to compensate for the trigger problem.

Hell Divers (shooting game)
Problem: spoiled R2 caused player unable to fire primary weapon
Solution: Go to game setting and choose "professional" for controller method.

GTA V (action game)
Problem: spoiled R2 cause player unable to fire their weapon, also caused player unable to fully accelerate while in driving mode.
Solution: Go to PS4 setting to remap the button configurations, switch between R1 with R2.

FIFA (soccer game)
Problem: spoiled R2 cause player unable to run fast
Solution: remap the button assignment

WWE2k18 (wrestling game)
Problem: spoiled R2 can't reverse the wrestler
Solution: Try to change button mapping in PS4 setting, or repair the controller/buy new one

There are methods to repair the R2 trigger on youtube without buying a new Dual Shock controller.
Most possible solution:
1) Adjust in-game setting (check if got trigger sensitivity to adjust)
2) Adjust PS4 console accessibility setting, remap the R1 and R2
3) Open up your dual shock controller, fix the silicon button padding (refer youtube videos)
4) Or just buy a new controller as a last resort

There are youtube video to repair the R2 trigger, some just realign the silicon rubber, some use silicon gum to repair the worn out part.

R2 button to reverse the wrester? Any in game setting solution besides replacing controller? Thanks for sharing.

In PS4 setting, accessibility setting supposedly can remap controller button (affect all games).

Did you manage to solve this problem? Through in-game setting or subsequent patch from game developer perhaps?

The trigger give better control over racing game acceleration, R1 or L1 do not offer that level of control. Xbox controller trigger is the best for racing game.
