same issue here 2 controllers now. returned 1 to the store will try the youtube fix posted earlier before returning, but in all honesty this should be fixed by sony. this is alot of money spent on faulty equipment.
The L1 and R1 buttons have been sticking on both of my DS4 controllers for weeks now. It's maddening when trying to play Pinball Arcade. I tried popping off the buttons, cleaning, and reattaching but it really doesn't help. I agree, this is faulty design and should be fixed by Sony. These controllers should not have a problem like this after a dozen hours of playtime. It's absurd.
I also have the same problem on both my Dualshocks - we should not have to take apart anything - has anybody tried phoning Sony support? Negotiate sending them one unit at time (if you have both) so you can still play and ask for a replacement, not just a "cleaning".
