The analog stick on my right joy-con was mess up after about of month of usage. Even if I wasn't touching it, the camera for some games and menu selection were moving to the right, it wasn't bad at first (it fixed by itself from time to time) but after a while, games became unplayable. It wasn't desync since using the control track thingy of the system menu never stopped working even if I moved far away from the console, it was just getting stuck on the right.
Had to replace the right joy-con.
Other than that I had no issues whatsoever.
