Version issues and modifications[SIZE=small]
[edit][/SIZE]
Sony's earlier DualShock 4 controllers (CUH-ZCT1 controllers) had wear issues with the rubber surface on both analog sticks which exhibited excessive wear or tearing after short-term use. In January 2014, Sony issued a statement acknowledging an issue on 10% of controllers.

In early September 2016, Sony confirmed a second version of DualShock 4 controllers, known as the
DualShock Version 2 (CUH-ZCT2), which hosts slight improvements over the original DualShock 4, including USB communication, improved triggers and joysticks, a longer battery life and the ability to see the light bar from the top of the touchpad. It released on September 15, 2016.

In the first generation controller, the light bar is a permanently illuminated, bright-colored light. The needless light pollution and battery drain prompted inquiries as to whether the light bar could be switched off by users. Sony executive
Shuhei Yoshida initially responded in the negative in July 2013,
[43][44] though game developers have the option to disable the light in game.
[45] In early 2014, the company announced that a future update would allow the light bar to be dimmed,
[46] which was delivered in 1.70 in April 2014.
