A Nintendo Switch actually helped to solve a murder investigation. On November 20, 2019, Matthew Wiser, a professor at the University of South Alabama, was shot and lost his life while his house was being burgled. One of the Items Stolen was Wiser's Switch. Authorities were able to track down the console's unique online signature when one of the perpetrators signed on to it long after the tragic theft had taken place, leading to investigators identifying Tiquez Timmons as one of the men involved in the incident. Timmons then implicated Derric Scott as the one who shot Prof. Wiser and burgled his house, while Timmons drove the getaway vehicle. This unique digital piece of evidence was actually used in court and helped to successfully convict the two young men of the crime.

The first batch of Nintendo Switch consoles suffered an issue where the left Joy-Con would frequently desync as the result of a manufacturing error. This could be remedied by placing a small square of conductive foam atop the Joy-Con's antenna traces, which would significantly reduce interference. Nintendo themselves would amend the desyncing issue in later batches of the Switch.
