No lag for me, but I did have that issue at first. What fixed it for me is getting 2nd Gen dualshock 4. First Gen uses a different Bluetooth radio, 2nd Gen has a radio that’s faster in communicating with the phone so eliminates all lag. I recommend u google how to tell 1st Gen and 2nd Gen controllers, they usually list serial numbers and stuff to tell them apart. Buy it on Amazon, and if u still get lag just return it.
